The unlocked hex-core i5-8600K from Intel’s latest Coffee Lake generation of processors is the new flagship of the i5 series, succeeding the Kaby Lake quad-core i5-7600K. The 8th generation of processors brings the largest performance uplift since Sandy Bridge by adding more cores at each of the i3, i5 and i7 product lines. Like the other Coffee Lake processors, the i5-8600K is built upon optimized 14nm architecture, marginally improved upon from Kaby Lake and Skylake. The 8600K has a 95W TDP and a nominal stock clock of 3.6 GHz, which boosts to 4.1 GHz for all six cores, 4.2 GHz for dual/quad and 4.3 GHz for single core. Early benchmarks put the i5-8600K’s effective speed 15% ahead of the i5-7600K. A 50% increase in multi-core speed is explained by two additional cores and thanks to the quad-core clock bump from 4 GHz on the 7600K to 4.2 GHz on the 8600K there is also an additional 5% performance boost across all workloads. All Coffee Lake processors require a 300-series chipset, making a straight CPU upgrade unfeasible despite sharing the same socket as their Z270 predecessors. Even though most games still use less than 4 cores simultaneously, the i5-8600K is a great choice for gamers but for $80 less, the 8350K which is faster than last years 7600K and only marginally weaker for gaming than the 8600K is certainly well worth considering as well. [Oct '17 CPUPro]

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.
