The Ryzen 9 5900X is second in AMD’s line-up of new Zen 3 CPUs. The 12-core hyper-threaded processor has base/boost clock speeds of 3.7/4.8 GHz, a 70 MB cache and a TDP of 105W. The 5900X took center stage in the 5000 series launch presentation where AMD gunned for Intel’s “best gaming CPU” crown. They showed the 5900X as being 26% better for gaming than the previous generation’s Ryzen 9 3900XT, attributing this to the new architecture’s faster single core speeds and lower latency. AMD also stated that the 5900X achieves, on average, 6.8% faster gaming performance than Intel’s 10-core i9-10900K. The details around AMD’s testing were not disclosed but it is safe to assume that 6.8% is the highest average lead that AMD are willing to stand by. Our benchmarks show that the 5900X’s slightly faster cores and the 10900K’s slightly lower memory latency balance out to yield similar performance. Whilst presenting their figures, AMD admitted that their 3000 series CPUs were far from “best for gaming” and conceded that the 10900K is approximately 19% faster than the 3900XT (our effective speed marks the gap at just 14%). Despite this clear performance deficiency, AMD supported 3000 series sales with an aggressive and successful marketing campaign to easily outsell Intel over the last 12 months. Given the real performance uplift observed in the 5000 series, and the absence of any meaningful marketing from Intel, we expect CPU sales to shift even further in AMD’s favour. Gamers that do not wish to pay “marketing fees” should investigate Intel’s $175 USD 11400F, the $660 USD savings would be far better spent on a higher tier GPU. [Nov '20 CPUPro]

The i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date. The many users that had the good sense to purchase this processor should feel in no hurry to upgrade as it's still no slouch, even by today's standards. The benchmark figures indicate that, even at stock clock rates, in terms of real-world performance this processor is approximately 20% slower than the best currently available, not bad considering its age. Given that the 2500K has an unlocked multiplier upping its performance by 10% with stock cooling should not pose much of a problem for the majority of owners. Here is a detailed performance comparison of the 2500K vs 4670K.  [Jul '13 CPUPro]

 Frequently Asked Questions

 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
