Four Powerful Processing Cores

With the Phenom II X4 series, AMD engineers have combined four cores into a single processor, giving you enough processing muscle for even the most highly threaded applications. Each core is equipped with 512K L2 cache, and all four cores share 6MB L3 smart cache between them. AMD has also included an ultra-wide, 4000MT/s bandwidth--enough to support all four cores effectively.

For users, this means that you'll be able to run all the latest software without the slowdown you'd experience with an inferior processor. Your computer will be able to handle multiple programs at once, and high-definition media players and video editors will run smoothly and efficiently. You'll also be able to enjoy next-gen games without any frame-rate hiccups.

Unlocked Multiplier for Powerful Overclocking

If you're an enthusiast looking to push the limits of PC performance, the Phenom II X4 965 makes it easier than ever to overclock your system. The unlocked multiplier allows you to manually increase the chip's frequency far beyond its stock values. You can achieve the best results by combining your processor with a reliable motherboard, high-performance SDRAM, and an effective cooling system. With the right combination, you'll be able to overclock your chip to unprecedented speeds.

Cutting-Edge Technologies for Faster Processing

The Phenom II X4 also makes use of several other performance-boosting technologies, including:

  • HyperTransport Bandwidth: Speeds up communication between the processor and memory, improving overall system performance.
  • Integrated Memory Controller: Actively scales bandwidth uses to match your computing needs, dramatically reducing slowdown.
  • 128-bit Floating-Point Unit (FPU): Allows processor to execute floating-point calculations with extreme speed.
Gaming without Slowdown

PC gaming continues to improve at a breakneck rate, with graphics, physics, and AI growing more realistic each year. But you'll need more than just a good graphics card to keep up with the latest games. For certain games that are heavily threaded, a slow CPU can quickly become a bottleneck for performance and can ruin your gaming experience.

Fortunately, the Phenom II X4 series has been specifically designed to handle CPU-intensive games. With its multiple cores, the processor can manage thousands of high-speed gaming calculations at once. The result is a smooth, immersive gaming experience, free of any stuttering or latency.

The Ultimate in Energy Efficiency and Cooling

AMD products are known for their stellar energy efficiency and the Phenom II X4 965 is no exception. The processor features AMD's proprietary PowerNow and CoolCare technology, which allow the processor to smartly regulate its own energy consumption. Having an energy-efficient computer doesn't just help keep costs down; it also generates less heat and helps your computer to run more quietly. It will even prolong your processor's life cycle, so you can enjoy it for years without having to worry about degradation.

The AMD Phenom II X4 965 Quad-Core Processor is backed by a three-year warranty.

I decided to take my grad money to the local computer store! After getting suggestions from my fellow computer nerd friends I decided to, among other things, pick up this CPU(AMD Phenom II x4 965 Black Edition AM3 125w) NOT the 145w version.

Just Cause 2 was stable in high resolution settings when outputting to my 40" LCD HDTV in 1360x768. Crysis Warhead runs great on enthusiast(max details) with Anti-Aliasing turned OFF. I'm running the CPU overclocked at 3.85Ghz. Ran Prime95 for 4 hours and it never restarted or hiccuped. When I had it at 3.96 it was not happy and restarted a minute into the stress test. At [...] they got it stable at 3.86. You can go higher but you are taking risks even with a better cooler. I have a Cooler Master hyper 212 Plus.

It runs about 53 degrees at stress. My motherboard (Asus M4A79xtd EVO unlocked all 4 cores)

The CPU seems to handle everything I can throw at it. Video Encoding speeds are decent. A two hour DVD movie ripping to h.264 in 720p will take about 25 to 30 minutes. Sherlock Holmes is a 25gb Blu-Ray disc and it ripped that in roughly 4 hours Full HD movie files are hot. And the file was only 4gb.

My friend has an i7 and I am sure he can encode Blu-Ray faster but at what cost? His i7 core still runs for around $600 and I got this CPU for less than $200!!!

This baby is so fast that Crysis is begging for Mercy in term of frame rate on 60 FPS on 720p and fast PC Performance and Power Saving , and Silent Fan Sound i give it more than 5 if i can.

I got this recently a special deal for it where it was 119.98 . I bought it cause my first time building a computer originally had a Athlon II x 4 640 however I screwed the first one up cause being a noob mistakes can happen. However I did have some pretty good upgrading hardware skills so I decided to give it another try and if that time It didn't work I'd scrap my self made pc project. I decided If i was gonna give it a last try I'd pick up the best cpu i could afford being this one and it was on sale. I popped it in everything came on no issues beenup and running for some time now. I noticed a great improvement performance wise over my other pc which is a Dell Optiplex 280gx . I decided to custom build cause I want a descent gaming pc for my sims Stuff I am into as well as First person shooter type games. Easier to self build rather then find upgrades for the optiplex. Everything went well minus the mishap and this cpu here made it a great computer so far I can't review much Windows 7 wise as I am using Ubuntu til i can afford to get Windows 7 I buy piece by piece due to my limited income I set aside each month for spending 135 for gaming and other electronics being thats my hobby . I am glad I got this cpu here it's good. and from other reviews I have read and vids on youtube The phenom's are better for gaming so far noticed improvement load wise even on farmville and other facebook games. The rendering of videos and such on youtube is much smoother. then the other pc. Everything runs faster and more high performance wise.Read more ›

We build computers so we are constantly looking at the best value of hardware for our builds. This AMD Phenom II QUAD 965 is really sweet. We were not sure about this choice. We had a previous phenom ii, the 940 that was underwhelming. But after looking at the various dual core options in AMD we gave it a go. This was a good decision. We like the Xigmatek S-1283 cooler. It is tall, but very quiet and at around $30 it is a super cooler. The cpu has moderate power requirements for reasonable operating temperatures. It is rated 125 watts. You have to make sure your motherboard takes those 125 and 140 watt cpu's. AMD finally solved the Phenom ii speed problem, and this cpu at 3.4ghz ROCKS. We use ASUS whenever we can for mainboards. So we married this cpu to a ASUS AM3 socket M4A88T-M motherboard that has great features and easy setup. We think the architecture of the cache on this processor makes it a better gaming choice over the competition. You can pay a little less for a 955 AMD quad, but stretch to the 965. You'll be glad you did! Our latest build with that Phenom II 965 and Asus M488t-M was completed with a Radeon 5770 video card and Kingson Blue DDR3 memory. We like the XM-5U front mount card readers and all SATA Western Digital and Liteon DVD-R for storage. It is plenty fast for the latest high graphic intense games. Very Nice and we did it ourselves saving a bunch,
