Pros: Brilliant value for money. Cons: It's not the 2400k which can be had for just a tiny bit more and offers a lot more flexibility in terms of overclocking. [Apr '12 CPUPro]

MORE DETAILS

The AMD Phenom II X4 955 is a quad-core processor based on the K10 micro-architecture. When it launched in Q2 of 2009, it was AMD’s fastest CPU. Given its base clock of 3.2 GHz, with appropriate cooling, this unlocked Black Edition chip can be overclocked to speeds in excess of 4 GHz. The 955’s effective speed of 63 isn’t impressive by today’s standards, but when coupled with a decent graphics card, it won't cause major bottlenecks for most games. The 955 was pitched against the high-end of Intel’s Core 2 quads, and now costs a fraction of its original list price as one would expect, however there are better alternatives on the market now. [Dec '14 CPUPro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
