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]

The Ryzen 9000 CPUs have the same integrated graphics, PCIe lanes, USB support and DRAM controller as the Ryzen 7000 series. The only difference is improved cores which have moved from TSMC's 5 nm process to 4 nm. The new cores offer 15% more performance under cherry-picked conditions but for latency-sensitive workloads, like gaming, they are just few percent faster. The 9600X, 9700X, 9900X, and 9950X are priced at $280, $360, $500, and $650, respectively, making them $80-$200 USD more expensive than the 7000 series. Since the 7000 series flopped (7800X3D somewhat excluded) due to unrealistic pricing, slow boot times, high platform costs and windows gamebar requirements etc., the 9000 series is more or less DOA. When the 9000X3D variants launch (expected in early 2025) gamers who play cache sensitive games such as SoTTR or Factorio with a 4090 and don’t mind frame drops, may find value in the 9800X3D. Meanwhile, Intel’s 12th and 13th gen CPUs continue to offer the best value for money in today’s market. Furthermore, Intel is scheduled to launch Arrow-Lake (est. +10% performance vs 14th gen) and Lunar-Lake (snapdragon competitive x86 battery life) this year, but they face serious challenges due to reliance on marketers who are mostly funded by AMD. Even if Arrow and Lunar Lake deliver stellar performance, without significant improvements in social media marketing: forums, reddit, youtube etc., Intel now face the very real risk of bankruptcy (third worst-performing S&P500 stock from Jan to Aug 2024). [Aug '24 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
