The Core i7-6900K is one of four new Broadwell-E prosumer CPUs. This model has eight cores with base and turbo frequencies of 3.2 and 4.0 GHz respectively. The 6900K is based on a 14 nm architecture, it has a TDP of 140 watts, 40 PCIe 3.0 lanes and no integrated graphics. Because of its MSRP of $1,100, the 6900K only makes sense for very niche use cases which include top end graphics design and video production. Comparing the 6900K and 6700K shows that for typical desktop use the 6900K only offers a gain of around 12% for a whopping three fold price increase. This is because desktop computing largely depends on single core performance and the Skylake i7-6700K is both clocked higher and has higher IPC due to its one generation lead over the 6900K. That said, as a workstation CPU the 6900K is bested only by the $2,000 flagship ten core 6950X. (6900K vs 6950X[Jun '16 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
