The Intel Core i5-6600K is based on the new "Skylake" 14nm manufacturing process. Sporting 4 physical cores with base/turbo clocks of 3.5/3.9 GHz the 6600K and its predecessor, the 4690K share the same basic configuration and disappointingly, offer similar performance. Comparing the 6600K and 6700K shows that the 6700K has faster multi and single core performance. The improved multi core performance is due to Hyperthreading which is the key differentiator for the i7-6700K. The gap in single core performance can largely be eliminated by overclocking the i5-6600K so although the stock effective speed is significantly higher on the 6700K, this gap diminishes significantly when both processors are overclocked. At a 30% discount, the 6600K is the better value gaming CPU. [Aug '15 CPUPro]

MORE DETAILS

Intel’s 13th gen. Raptor Lake CPUs offer around 10% faster gaming and 45% faster multi-core performance than their predecessors. The new CPUs are compatible with DDR4 memory and Z690/B660 ($150) motherboards. New high-end gaming builders need look no further than the 13600K. The 13600K beats AMD’s flagship 7950X in gaming and almost matches the 7900X in multi-core performance. Extreme workstation users may find value in the 13700K or 13900K. Gamers on a tight budget can save $40 USD with a 13600KF which is a 13600K without integrated graphics. Although Ryzen 7000 has weaker multi-core, weaker single-core, higher platform costs and higher unit prices AMD have a 3D joker up their sleeve (7800X3D est. 2023). Via “Advanced Marketing” on youtube, forums, reddit, and twitter AMD will demonstrate that their upcoming CPU is the “best in the world” and offer “proof” by way of a small handful of obscure workloads. Games that few people play e.g. (Factorio, SotTR) will be cherry picked, video footage of the gameplay/settings won’t be provided and frame drops will be conveniently ignored. This playbook has easily outsold Intel in recent years but with every overhyped release, consumers lose trust in AMD. Based on social media/press coverage, you would never guess that the combined market share for all of AMD’s Radeon 5000 and 6000 GPUs amongst PC gamers is just 2.12% (Steam stats). Meanwhile Nvidia’s RTX 2060 alone accounts for a whopping 5.03%. Largely thanks to marketing incompetence, Intel is existentially motivated to deliver material annual performance improvements. Consumers can look forward to Meteor Lake (14th gen) in less than a years time. [Oct '22 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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
