The Core i7-6800K is the weakest of four new 14 nm Broadwell-E prosumer CPUs. This model has six cores with base and turbo frequencies of 3.4 and 3.8 GHz, a TDP of 140 watts and 28 PCIe 3.0 lanes. The 6800K closely matches, and supersedes, the very popular Haswell-E 5820K. Because of its MSRP of around $500, this CPU only makes sense for niche use cases which include graphics design, video production or multi GPU gaming. Comparing the 6800K and 6700K shows that for typical desktop use, at stock clocks, the 6800K actually lags the 6700K by around 10%. This is because desktop computing largely depends on single core performance and the Skylake i7-6700K is both clocked higher (Base clock 4.0 GHz vs 3.4 GHz) and has higher IPC due to its one generation lead over the 6800K. If the 6800K proves to be a capable overclocker then it may challenge the 6700K on a range of core-heavy use cases, time will tell. [Jun '16 CPUPro]

Early Q3 of 2019 sees the release of the new Ryzen 5 3600X: a hex-core, 12-thread processor. AMD are releasing five new CPUs based on their latest Zen 2 microarchitecture which delivers approximately 13% better IPC than the previous 12nm Zen+. For workstation builds the 3600X is viable, however, the $200 USD Ryzen 5 3600 represents a far better value proposition. The additional $40 USD for the 3600X basically buys a better cooler (Spire vs Stealth). This allows for an extra 200 MHz of extra base and boost clock: 3.8 / 4.4 GHz on the 3600X vs 3.6 / 4.2 GHz on the 3600, this translates to approximately 2% higher overclocked performance for 20% more money. Neither of the stock coolers on the 3600 or 3600X are as effective as a $20 USD aftermarket cooler such as the Gammaxx 400. The 3600 with a Gammaxx 400 outperforms the 3600X with a Spire cooler and when both use a Gammaxx 400 they are more or less identical. The 3600X SKU is basically a marketing gimmick designed to milk unsuspecting consumers. Comparing the 3600X to Intel’s overclocked flagship i5-9600K shows that although the 3600X has 29% faster 64-core speed, it is around 11% worse for gaming (sub eight core performance). Additionally, the 3600X's memory controller, although significantly improved over previous Ryzen iterations, still has limited bandwidth and high latency which can also impact gaming. The arrival of Zen 2 marks the end of the "Sandy Bridge (i5-2500K)" era, Intel can no longer rely exclusively on their single-core advantage to dominate the market, they must also compete on price. [Jul '19 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.
