First of all, the FX 4100 is a really "open" CPU, it lets you toy around with a lot of its features and options thanks to the fact that it's unlocked. People who are a little more than just computer literate will love this, cause it enables you to tune your processor the way you want it and explore its limits. AMD has done a very good job on this side and provides the tools to do just about anything you want. If you own a good motherboard (and you should with such a processor) as I do (Gigabyte 970A-UD3), you can really unleash some of the hidden potential of the FX.
The other interesting thing about the FX is that it's a semi-intelligent CPU if you will. It adjusts itself to use more or less power to execute certain tasks. Or so it should. The problem is, it doesn't seem that the software really understands that. Sometimes, you will get very good results performance-wise and then another task will just behave so poorly that it'll make you regret your old Athlon or Phenom. Another issue is that certain games for example, do not want to run at all with an FX installed. Red Faction: Armageddon is one such game. This is quite sad and honestly, it feels like the FX was just released a bit too soon, with lots of promises to wipe out the bugs at a later point in time.Read more ›
You can't really beat $110 (plus currently 10$ off if you pair it with a Gigabyte Am3+ motherboard). The other new AMD processors may have more cores, but the truth is, most applications currently used at home don't take advantage of the full potential of Quad core processors, let alone the 6 and 8 core processors. To me, the added cost of buying those processors (or even any of the Intel processors) just isn't worth it right now. This processor is by far the best bang for your money (for now at least) and if you are building a new computer or replacing an older one, then I would recommend this processor.
This processor doesn't really perform all that much better that any of the Phenom II processors. If you currently have one of those processors, I would not recommend upgrading to this (or any of the other new Bulldozer processors). What little difference there is, would not be worth the cost. I would wait for the next processors to come out (I think I am hearing April for those, but I'm not sure).
I am giving this one a 5 star rating because it delivers exactly what it advertises, a solid quad core processor at an exceptional price. There are better processors available, but you will also have to pay a lot more for them.
I bought this as well as numerous other parts during the black friday/cyber monday sales to put together a very adequate computer. Note that this is a AM3+ socket!! At its release, a lot of motherboards didn't have the socket support for AM3+ yet, but they are definitely out now. As a suggestion, check out ASRock's extreme boards, and always do research before you buy. Furthermore, try not to take Benchmarks as the end-all to buying a processor. A CPU for this price and speed will do everything you want it to, unless you're rendering large 3D models or video editing professionally (but you shouldn't be looking in this price range, anyway). Potentially, you can get the support for this AM3+ socket now (as it will be the new AMD socket type for a few generations), and upgrade later when "Piledriver" releases or you have some extra cash for an upgrade. This is a "Bulldozer" AMD product, and has a 7.2 on the WEI (Windows Experience Index).
To note, this processor supports up to 1866mhz memory speeds without toying with OC'ing, but making it easier to OC the CPU compared to Phenoms (nothing against Phenoms, just relaying information). Albeit, I read that it will only do this with 2 sticks, but trying to fill all 4 busses puts strain on the memory controller anyway... so try to get maybe 8gb in 2 slots (2x4gb). This processor compares to Intel's i5-760, which is about $215 (1/16/2012).
Also, Windows was still behind on supporting FX processors when they were released for multi-threading.Read more ›
Cons: Low max tmp, some motherboards (AM3) don't support it out of the box, even though they're supposed to - they won't until you update their BIOS, requiring another AM3 slot CPU to do so.
Outperforms my old i7 940 - substansially in some games and applications. The price is so low while on a budget build I was able to get a rather snazzy motherboard (Asus Sabertooth 990FX). 4.6ghz on air cooling (212 Hyper Plus) with 30c idle temps.
Due to lazy software developers very few applications are properly multithreaded, so the benefits of having a extra four cores (that which are idle 90% of the time, for example on the FX 8150) is rather minimal.
Are expensive 420 core procressors the future? Absolutely - but not until software catches up, until then, save yourself some cash, get this processor instead.
