The i9-11900K is the fastest CPU in Intel’s 11th Gen Rocket Lake-S lineup which brings higher IPC (early samples indicate +19%) and 50% stronger integrated graphics. There are also 500 series chipset improvements including: 20 PCIe4 CPU lanes (up from 16) and USB 3.2 Gen 2x2 (20 Gbps up from 10 Gbps). Rocket Lake’s IPC uplift translates to around a 10% faster Effective Speed than both Intel's 10th Gen and AMD’s 5000 series. Despite Intel’s performance lead, AMD continues to outsell Intel. Given the scale of Intel's operation, it’s inexplicable that their marketing remains so neglected. Little effort is made to counter widespread disinformation such as: “it uses too much electricity” or the classic: “it needs more cores”. Intel’s marketing samples are routinely distributed to reviewers that appear better incentivized to bury Intel's products rather than review them. Not enabling XMP or only testing with BIOS power limits enabled is akin to leaving the handbrake on during a race. Mind-numbing “scientific” and rendering benchmarks are presented as gospel. Different games, mostly unplayed by real users, are cherry picked for each “review”. When it's convenient, canned game benchmarks are chosen such as Ulletical’s CSGO which runs at nearly double the in-game fps. Credible benchmark data, which necessarily includes replicable video footage from popular games, is the exception rather than the rule. At every release, AMD’s marketers coordinate narratives to ensure another feast of blue blubber. Nonetheless, towards the end of 2021, Intel’s Golden Cove is due to offer an additional 20-30% performance increase. At that time, with a net 30-40% performance lead, Intel will probably regain significant market share despite AMD's class-leading marketing. In the meantime, most PC gamers need look no further than the 11400F. [Mar '21 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i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date.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]

 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.
