Fantastic chip, outperforms the $489 i9 9900k in productivity.

Reviewed in the United States on July 15, 2019

Style: ProcessorVerified Purchase

This chip is a beast! Was able to snag mine from 'AMD authorized reseller'. Came in 1 day when it was estimated to take 3. This thing blows everything out of the water at this price point. On par with the intel 9700k in gaming for $70 less, and better than the $489 i9 9900k in productivity and multitasking. First time buying an AMD chip but with their recent innovations its hard to justify buying Intel.

No point in buying a 3800x

Reviewed in the United States on July 20, 2019

Style: ProcessorVerified Purchase

TL;DR: Really good and stable processor for all around workloads and gaming. Still has a good stock stable boost clock of about 4.2GHz with a good cooler about the same as the 3800x without the extra $$$. Be care full of the Motherboard you buy as it may be troublesome updating the bios on x470 and lower boards to support the 3rd generation of AMD Processors.

Full Read:
For gaming I see this baby stay stable clocks at 4291-4316MHz and sporadic single core turbos up to 4392MHz. The 4.2 ghz all core stable boost clock is about the same as a 3800x (according to other reviewers) but the 3800x has a bit more of a higher single core sporadic burst, but probably not worth the additional $70 for the tiny performance difference. I have a Phanteks PH-TC14PE (nh-d15 comparable) and during a 30 minute Aida 64 stress test (picture) the 3700x stays at 85c and 4070MHz average.

This processor is paired with a 570x Aorus elite so I wouldn't have the trouble of doing tons of CPU swapping on a b450 or an x470 board to update the bios (plus I saved $70 over the 3800x). Some of those boards have quick flash capabilities, but if they don't then it is just time consuming and a bit painful to install an old 2nd or 1st gen cpu, update, then reinstall the new processor and make sure it actually works. Also as of 5/20/19 a bunch of Ryzen 3xxx out of the box compatible B450 boards are announced, but nobody knows when.

I did a motherboard & CPU Swap in my system and had a lag filled windows experience, so a windows reinstall was necessary to get it to run smoothly (your actual experience may vary). After the reinstall it's been nothing but buttery smooth.

It needs some tweaking

Reviewed in the United States on July 20, 2019

Style: ProcessorVerified Purchase

I'm happy to see that it's finally in stock at MSRP. I got the 3700x to replace a 6700k system which broke. The ASUS GENE VIII motherboard failed. So it was time for an upgrade and go back to AMD. Last AMD part I had was the AMD FX-8350 back in 2012. The 3700x seems to work just fine, cinebench 15 score when from 850 to 2145, so that's a thing.

Edit: 7/30/2019
I'm docking 2 stars. The chip is great and all, but it runs too hot at idle, 40+ C on an aio, 24 C ambient.
I'm comfortable having my pc run hot during games, etc.., but not at idle.
At idle the system keeps boosting to 4.2+ Ghz all the time.
It's like it doesn't know how to clock itself down (even on AMD balanced profile, latest Win 10 1903).
Disabling boost solves the temp issue, but that's not an option.
This is probably the early adopter tax and I hope they fix it in the bios.
It could also be the ASUS board which is too aggressive with voltages.

Edit: 7/31/2019
+1 star, Windows power saver power plan is what I wanted.
Idles at 32 C at 25 C ambient, core voltage a 0.944 V instead of that crazy 1.45+ V
I does sacrifice some standby performance, but that's ok.

Edit: 9/16/2019
+1 star, the ABBA bios update fixed my idle power problem.
It just needed some tweaking.

Amazing CPU!

Reviewed in the United States on July 21, 2019

Style: ProcessorVerified Purchase

This CPU made a huge difference in gaming coming from a R5 1600 OC 3.8ghz. There is absolutely no reason to overclock as it boosts itself as much as it can. Hit 4250mhz all core on BF V on a Gigabyte AX-370 Gaming K5 with BIOS update (while the new board is in shipping). With a Corsair H100i v2 max temp under full load was 80c, normally around 65c in demanding games. FPS in games went up by roughly 30 letting my 2070 hit 144 consistently with 0 dips.

Affordable Intel-Killer!

Reviewed in the United States on July 22, 2019

Style: ProcessorVerified Purchase

Not only does this CPU absolutely blow Intel's current line-up out of the water, it also has the product quality to show for it. I never thought I'd hear myself say it but I'm a firm believer in AMD and what the Zen chips are accomplishing here after seeing it for myself. This CPU is currently tackling Star Citizen on one front and streaming on the other end, all while unzipping some files and keeping up with everything else that demands it. Not only is it running fairly well it's also keeping stable temperature wise. Under full load the temps average at around 65c-70c and that's just running the stock Wraith Prism cooler.

Definitely eager to test out this chip with a water cooler slapped onto it and a slight OC to kick it into high-gear. All in all I really can't complain for what I've received. It's an affordable processor that'll do just about anything for you without much trouble and still have room for more. Don't worry about paying "premium" pricing for "top of the line" and "state of the art" CPUs when you can get all of that here for less, with more!

Disappointing Update.

Reviewed in the United Kingdom on July 24, 2019

Style: ProcessorVerified Purchase

*UPDATE*
I have found overclocking to 4250 with 1.3v being optimum on both temps and performance. Obviously it'll depend on motherboard and memory, but it's only 5-10oc hotter than the 2700X now. I do however get the odd crash in WOW but it's OCCT stable after an hour /shrug

Also note: the boost clock frequency AMD state is sadly for ONE CORE ONLY, you might get 2 or even 3,but not all - which is why PBO gives better results, basically though some cores can be 100mhz+ less than advertised boost and thus trying to manually clock to those is impossible... We're buying binned 3800Xs here.

There's quite the riot at the moment as intel claims it's boost speeds are all cores and so we're AMDs on the 1000 and 2000 series, so not sure why they've gone down this route now, but it leaves a sour taste in your mouth regardless!

*ORIGINAL REVIEW*
Everyone was expecting 4.5ghz and intel beating performance after the success of the 2700X, dropping down to 7nm was going to be a game changer, and it has, it's pushed people towards Intel again. Let me explain.

My 2700X @4.2ghz has been rock solid till recently, anyway, 30-40oc desktop, 50-55 gaming.

The new CPU comes and I plop it in after nicely cleaning the hell out the water block with Tim cleaner - a proper job, with some kryonaut bobbed on, 55oc bios temps, odd, hit windows - see 60s get confused.

Shuts down, rips off the cooler, cleans and reapplies expensive kryonaut on. Boots, 55oc..poggers.

Long story short, cpu runs hot, so hot there's no argument for intel vs amd for temps now.

Performance wise, still slower than a 9700k, but it's closed the gap.

A pain to cool, be lucky if you hit 4.3 all cores.. Bearing in mind my 2700X was stable at that but the temps were too high.

So I leave PBO on and have it at stock.. Run a ICCT Bench and my cpu hits the low 80s, suddenly drops to 75oc,and then goes back up to 80s and then boom black screen.

Reboot and bios reports overheating cpu.. Pogchamp.

So TLDR, Its quicker than last gen but 10-20oc hotter, it uses more volts, PBO overclocking better. Runs higher vcore on idle than load.

Would i recommend this? Not unless you wanted PCIE4 for drive speed, or unless the 9700k is out of stock.

I have a h110i GT at the front of a phanteks enthoo luxe (stripped) with 4x fans push pull on the rad (3x akasa sp fans), photos above, it's cool in there good airflow so it's not a potato cooler at fault here.

There's rage rant all over reddit and amd forums, feels like we're still beta testers!

Great CPU.

Reviewed in the United Kingdom on July 20, 2019

Style: ProcessorVerified Purchase

Bought 3700x as a replacement for my Ryzen 5 1600 and put it in my ASUS Prime B350-Plus running the latest BIOS (Version 5007). Out of the box the 3700x hits the max boost of 4.4GHz when not all cores are needed and when all cores are under load mine settles at 4.1GHz. Idle temps do seem to bounce around somewhat with it constantly settling between 36c and 43c and under load running Prime 95 the processor settles around 62c. Of course it is hard to show any sort of performance increase over the R5 1600 without many benchmarks etc but take my word for it the Ryzen 7 3700x is worth the investment.

Excelente procesador tanto para juegos como para edicion.

Reviewed in Spain on July 29, 2019

Style: ProcessorVerified Purchase

Ryzen 3700x

Montado en ASUS Crosshair VII y con 16gb de gskill 3600, voy a valorar lo que me ha parecido este procesador.
En si ha dado un buen paso en comparación al 2700x que es el que tenía anteriormente, de media sobre 10/20 fps a los juegos que normalmente juego, no entrare a valorar con otros juegos que nunca he usado, en multitarea la verdad que también he notado algo de mejoría respecto al 2700x.

En cuanto a compatibilidad con la memoria, de momento no he tenido ningún problema en ponerlas a 3600, también decir que justo me ha llegado cuando han sacado el micro código AGESA 1.0.0.3AB para Asus, pero también me he encontrado con algún, pero, que ahora los comentare.

Hacer OC ahora mismo con las bios que hay es bastante absurdo, saca bastante mas rendimiento en modo auto y con el PBO, pero también tiene algunas cosas que no me han gustado, por ejemplo el Voltaje se dispara, AMD ya ha salido diciendo que es normal, pero para mi gusto demasiado alto, tiene picos que casi llegan a 1.5v, luego las temperaturas dentro de Windows si no se activa el modo Balanceo de RYZEN son bastante altas, estamos hablando de una media de 50º y eso que voy con liquida custom, con la actualización del chipset y el modo balanceo la cosa ya cambia, esta en idle sobre 38º, en full carga alcanza sobre los 70º también por el alto voltaje que hay, espero que en poco tiempo mejoren este aspecto como en las anteriores generaciones.

En cuanto si vale la pena coger la plataforma X570, en mi opinión por el precio que tiene si no es que necesitas el PCIE 4.0 mas vale coger una B450 o X470 y el dinero que sobra invertirlo en otro apartado.

El apartado que menos me ha gustado, también hay que decir que depende del fabricante ahora mismo, es en el apartado de BIOS, apenas puedes tocar muchas cosas, dado que a la mínima ya no arranca, lo mejor a día de hoy estando como están la BIOS que se tienen que pulir es dejarlo en modo AUTO el apartado del procesado.

Resumiendo, me parece una gran procesador y AMD ha vuelto hacer un producto muy competitivo, pero con precios ajustados, aun no hace ni un mes que han salido y bueno creo que las bios las tienen que pulir aun bastante, espero que para setiembre ya estén bien pulidas y poder aun exprimir mas el potencial de este procesador, a medida que vayan mejorando iré subiendo que tal va la mejora.

EDITO:
Justo ayer sacaron nueva BIOS y nuevo código de chipset, ahora ya he podido tocar parte del overclock, decir que en el tema voltajes aun me hace extraños o no mide muy bien la temperatura pero con el tema de OC en BIOS ahora va perfecto, he conseguido poner en nada las rams a 3600 con cl 16-16-15-15-32-42 y uns subtimings bastante bajos, el procesador lo he subido hasta 4.3Mhz con un voltaje de 1.280v no obstante las temperaturas me siguen exactamente igual, solo bajan las temperaturas a rangos normales cuando el procesador lo dejo en stock y si PBO ni nada, el stock del mismo son 3600Mhz todo lo que pase de allí las temperaturas se disparan, supongo que tienen que pulir aun mas los microcódigos y las bios, pero de momento van bien encaminados, cuando pongan otro cambio volveré a editar.

定格クロックとブーストクロックでは消費電力の特性が変わる。

Reviewed in Japan on August 31, 2019

Style: ProcessorVerified Purchase

RYZEN 2700Xから乗り換え(CPUだけ交換)。
構成：RYZEN 3700X、X470 AORUS Gaming 5 Wifi、RADEON RX570
個人的には定格で使用中。
2700Xの定格以上ブースト最大未満の性能を、同じCPUクーラーで2700Xの定格時の温度より10度以上低い状態で発揮している。

良い点
ピークパフォーマンス、ワットパフォーマンス、コストパフォーマンスの高さは今更言うまでもなく良い。
IPCの向上により強化の目玉のAVX2以外でも十分2700Xより(クロックが0.1GHz下がっているのに)高速。
BIOSアップデートさえしてあれば2700Xなどからポン付けで移行出来る。

重要な点
・定格(CPB(コアパフォーマンスブースト) OFF)では省電力だが、ブーストクロック(CPB ON)では消費電力が跳ね上がる。
自動OCであるCPBをONにすると、規定の消費電力、電圧、温度、最大クロックのいずれかの天井になるまで全力でOCされる。
この時の消費電力枠が既定(PBOで弄らない状態)で88Wの設定で、TDP65Wと謳われている仕様から大きく上昇する。
これによって消費電力やリテールクーラーや小型クーラーでの冷える冷えないの評価がブーストするしないでは大きく変わってくる。
(同じ3700Xでも、ある人はCPB ONでアツアツと言い、別の人はCPB OFFでヒエヒエと言う。そして大抵CPBのON,OFFは明言されない。)

・特定のクロックを閾値として消費電力特性が大きく変わる。
ブーストクロックにするとワットパフォーマンスが急速に悪化する。消費電力制限に対してクロックの伸びがよいのは1.1GHz～3.45GHzぐらいらしく、勾配の緩い直線状のグラフに、3.45～上限が勾配の急な直線状のグラフになる。
(3700X PPT curve Cinebench R20 等で検索)
この為、自力で電圧等を相当詰めない限りはワットパフォーマンスが最も高いのは3.45GHz付近、ちょうど定格の3.6GHzぐらいと言える。
この特性を利用して、3800XではTDPを105Wに引き上げることによって定格クロックを上げ、
また、3900Xは3800Xより0.1GHz下げ、3950Xでは3700Xより0.1GHz下げることによってTDP105Wに入るようにしている。

というわけで、
定格で使うかブーストクロックで使うかによって消費電力(=必要なCPUクーラーの性能)が変わってくるので、
どちらを目指すのかを良く考えて一式をそろえたほうが良い。
個人的には十分な性能を持ちつつ最もワットパフォーマンスが良く手軽に設定出来る定格(CPB OFF)がオススメ。

Style: ProcessorVerified Purchase

se acquistate questa sì più credendo che non scaldi perché a 7 nanometri di sbagliate. perché con il suo kit di ventilazione è un piccolo forno. le temperature sono alte perché funziona 1,4 volt per avere il boost e arrivare a 4,4ghz.
tiene senza problemi i 4,3ghz con tutti i core a 1,4 volt usando il software ryzen master. sul bios ho lasciato tutti i parametri in automatico. consiglio vivamente di prendere un kit a liquido Io ho preso il corsaro h100i RGB Platinum. e si abbassano di 10 ° le temperature medie e di 20 ° quelli di picco.
assipiu ma non ha dato nessun problema in Windows e con tutti i giochi funzionano alla grande. anche quelli di 10 anni fa.
AMD è riuscita ad eguagliare se non superare Intel in tutti i test. rimane solo il problema delle applicazioni che sono fortemente single core penso ad AutoCAD
perché Intel ha frequenze nettamente superiori le nuove CPU arrivano a 5ghz. questa si ferma 4, 3 e 4,4. ma le prestazioni per singolo ciclo di clock sono nettamente superiori a vantaggio di amd.
non c'è più nessun motivo per rimanere legati ad Intel. passando da 4790k 4,2ghz ryzen 3700x a 4,3 gigahertz aumentato le prestazioni nei test di 2,6 volte. per far funzionare ottimamente queste CPU sono necessari e RAM ddr4 3600 mhz. così il bus di sistema infinity fabric rimane a 1800mhz con rapporto 1 a 1. non ha nessun senso prendere RAM più veloci non c'è un aumento di prestazioni. meglio ridurre i timings.

In questo caso la situazione è un po’ strana, la temperatura in idle oscilla tra i 45 e i 65 (non scherzo monitorando la temperatura ho questi sbalzi). A carico massimo invece no supera i 73 gradi. Aspetto un eventuale aggiornamento del bios.

Programmer/Heavy Load Tasks... Not for gaming.

Reviewed in India on November 22, 2019

Style: ProcessorVerified Purchase

Cons:
Never touches 4.4
Needs good ventilation, dont put this in a crammed case, it will get hot (I had to buy extra fan to keep it below 90 under load)

Pros:
8 core, if you are a heavy user(gaming doesnt count) its for you. (For just gaming go for 3600 or Intel with higher clocks)
Programming and Rendering tasks take less time.

Ryzen 7 3700x, nervoso e reattivo come un'auto sportiva.

Reviewed in Italy on February 10, 2020

Style: ProcessorVerified Purchase

Ryzen 7 3700x
Non starò a scrivere di prestazioni o benchmark, di queste cose se ne trovano a valanga in rete.
Voglio invece scrivere di ciò che mi ha inizialmente confuso e rassicurare coloro che ne acquisteranno uno, o che confusi quanto lo ero io, cercano eventuali risposte anche nelle recensioni.

Già dal primo avvio da bios, la prima cosa che salta agli occhi è il suo Vcore da 1,44V apparentemente spropositato, tanto da sembrare sbagliato. Una volta caricato il sistema operativo, utilizzando qualsiasi programma di monitoraggio, noterete dei picchi assurdi da 1,5V anche in idle.
Ho letto una marea di forum e discussioni a riguardo, e quasi tutti, arrivano infine alla stessa conclusione. Il vostro 3700x non ha nessun problema, come dice la stessa AMD (ho letto ciò nei forum ma non ho mai letto il comunicato ufficiale), questi Ryzen sono programmati per comportarsi così.
A quanto pare, per dirla molto in breve, se lasciato tutto in automatico da bios, il Vcore è relativamente ad alto voltaggio ma basso amperaggio, con l'aumentare del carico di lavoro del processore, aumenta l'amperaggio e di conseguenza si riduce il voltaggio, mantenendo un rapporto corrente tensione, atto a garantire le massime prestazioni, ma sempre entro i limiti di sicurezza del processore. Ho letto di molti che preoccupati castrano il processore, dandogli -0,15V di offset, cosa che inizialmente avevo fatto pure io.

Le frequenze appaiono altrettanto anomale, in idle, non le vedrete scendere sotto i 3,5GHz, e basta muovere il mouse, per svegliare il boost, e farle salire a 4,4Ghz.

Un informatico su un forum, descriveva i comportamenti del Vcore e delle frequenze in idle, con un'analogia molto semplice e chiara. “Questi Ryzen, si comportano come un pilota su un auto sportiva al semaforo del via. Continua a dare colpi sul gas per tenere i giri del motore alti, mantenendolo pronto e reattivo al momento del verde”.

Il problema per molti, è che questo comportamento può diventare alla lunga fastidioso, sopratutto perchè si ripercuote sulle temperature e sulle ventole.
Anche in idle, la temperatura può oscillare di 15 C° in 2 secondi, e vista su un grafico, appare come un dente di sega, con bruschi aumenti, e più lente discese nel tempo. Con il mio dissipatore Noctua NH-D14, la temperatura, oscilla tra i 30C° e i 40°con picchi fino a 60C°, ma leggevo di persone che avevano più o meno lo stesso andamento anche con raffreddamento a liquido.
Il Noctua per fortuna è silenziosissimo e non percepisco le variazioni di velocità delle ventole, mentre le ventole del case, le ho tutte pilotate da un fan controller esterno, quindi non reagiscono in automatico alle temperature.

Ovviare a questo problema è comunque molto semplice. Basta aprire le “opzioni risparmio energia (di Windows)/AMD Ryzen Balanced/risparmio energia del processore” e ridurre del 1% il “valore massimo prestazioni del processore”, portandole al 99%. Io ho ridotto anche il valore minimo al 98%, essendo come valore predefinito il 99%.
Questo elimina l'effetto dei “colpi sul gas”, bloccando il boost e stabilizzando Vcore, frequenze, temperature e di conseguenza anche le ventole. Personalmente non l'ho provato su programmi o lavori gravosi per la cpu, ma sebbene questo espediente blocchi il boost in idle, o su programmi banali come firefox e vlc, nei giochi si attiva comunque e senza aver riscontrato cali di fps.

Nella prima parte della foto (a sinistra), è possibile vedere “i colpi di gas” sulle frequenze e l'andamento a dente di sega delle temperature, anche se le uniche applicazioni aperte sono quelle per il monitoraggio. Da metà foto verso destra, tutto stabilizzato riducendo il processore dell'1% come sopra descritto. La temperatura della stanza era tra i 18C° e 19C°.

Una volta capito, mi ci sto trovando a meraviglia e lo consiglio senza indugio.
Non dò 5 stelle perchè potevano inserire un altro profilo meno reattivo oltre al “Balanced”, evitando così, di far passare le giornate sui forum a molte persone come me. Chi sà, forse lo inseriranno in futuro.

だいぶ好印象

Reviewed in Japan on July 27, 2019

Style: ProcessorVerified Purchase

もう5年以上前のi7-3770kからの買い替えです。
日常におけるPCの使用率はかなり高いものの、エンコードや最新の重いゲームはほとんどしなかったためGPUさえ買い替えていれば3770kでもあまり不満はありませんでしたが、そろそろマザーなども含めた老朽化による突然の故障への備えと、周辺機器の新しい接続規格が使用したかったのでビデオカードは据え置きでPCを一新しました。

結果Adobeのソフトや業務用ソフトは全面的に早くなりyoutubeを3窓くらいをしていてもCPU使用率は30%くらい使っていたものが10%前後におち、cities:skylineは処理落ちやCPU全力になることもほぼなくなり、minecraftは更になめらかに。Dxtoryでキャプチャしながらのプレイも前と同じくHDDへの書き込みをしていても軽くなりました。
ブラウジングやテキストエディタなどは3770kの時点でもう表示速度に問題がなかったのでそのへんはあまり変わりません。
クーラーは付属のものを使用せずサイズの超天と組み合わせて温度は大体50度以下安定。エンコードさせてみたときの温度は70度前後という感じでした。もっと能力の高いクーラーを組み合わせると更に10度くらい下がるかもしれません。
まだ一週間程度の使用ですが現時点ではとても満足です。

Alter Sack

Ein Hammerteil

Reviewed in Germany on August 24, 2019

Style: ProcessorVerified Purchase

Mehr aus Interesse als aus Notwendigkeit habe ich diesen Prozessor gekauft.
Das alte System bestand aus einem 1700x auf einem Gigabyte Gaming 5 (X370) mit 2*16GB DD4 3000 und einer NVMe mit 240GB (Samsung Evo).
Das Board blieb (aktuelles BIOS), der Speicher wurde durch DDR4 3333 und die NVMe durch eine 2TB MP510 von Corsair ersetzt. Und die CPU natürlich durch den 3700x.
Der Speicher wollte mit maximal 3266 stabil laufen - ist ok, alles > 2400 ist laut Spezifikation des Mainboardes ohnehin Overclocked - speziell designed wurde es vor 2 Jahren für solche Geschwindigkeiten sicher nicht.
Der beim Ryzen mitgelieferte Boxed-Kühler ist ok, bei 28 Grad Raumtemperatur habe ich damit die CPU im Stresstest aber auf 92°C gebracht. Nicht schön, aber wer längere Maximalperformance möchte kauft ohnehin etwas besseres für die Kühlung.
Die Performance selbst ist Wahnsinn - 20-50% Mehrleisung je nach Szenario gegenüber dem 1700x bei maximal 85 Watt laut hwmonitor - der 1700x hat sich hier glatt 120 Watt gegönnt.
Windows wurde in der aktuellen Version natürlich auch neu installiert. Das aktuelle Gefühl ist so als hätte man bei 130 auf der Autobahn gemerkt dass man die ganze Zeit mit angezogener Handbremse unterwegs ist.
Fazit: Top CPU, selbst ein Aufrüsten vom 1700x lohnt sich wenn man nicht zu sehr auf das Geld schauen muss. Beim Board war ich dann trotzdem geizig, die x570 sind einfach unverschämt teuer im Moment und bieten zu wenig Mehrleistung. Der x1700 kommt jetzt mit den "alten" Komponenten auf ein B450 Board als Zweitrechner.

Sfortuna ha voluto che la CPU difettosa capitasse a me. Per fortuna, d'altro canto, sono smanettone e smonto il PC spesso e durante uno di questi smontaggi ho notato una crepa sul corpo del processore che prima non c'era. Chiedo la sostituzione e solo dopo farò una recensione completa.

Ich kann nur sagen, dass ich die Cpu auf das Gigabyte Auros Ultra gepackt habe und mit Hilfe des Alphacool XPX kühle. Bei mir läuft die Cpu ohne dass ich etwas machen muss vom Start an mit
4,4 GHz auf allen Kernen. Von mir daher eine klare Kaufempfehlung.

amd exaggerated clock speeds and AMD Rewards scam

Reviewed in the United Kingdom on August 21, 2019

Style: ProcessorVerified Purchase

This CPU barely if at all hits speeds on box, worst of all AMD rewards process, after providing proof of purchase still cannot redeem rewards offered with this product. Amazon should be ashamed advertising this with the AMD rewards as it is a borderline fake offer in my experience.
