The Core i7-6700K is Intel's latest "Skylake" flagship processor. It replaces the hugely successful i7-4790K and takes the crown as the fastest mainstream consumer CPU available. Comparing performance and specs between the 4790K and 6700K shows that the configuration is largely unchanged (same base clocks, cores, threads) but the improved manufacturing process (14nm) brings a small reduction in TDP and a performance improvement of 8%; almost exactly the same jump as between the Ivy Bridge 3770K and Haswell 4770K. Owners of any unlocked-K Intel CPU from Sandy Bridge or onwards still have no real reason to upgrade as the performance improvements are largely academic but the i7-6700K will be the CPU of choice for the vast majority of top end PC builds in 2015. [Aug '15 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
