Intel’s core i9-7900X, from the Skylake-X series, is Intel’s latest 10-core, 20-thread flagship processor. It's the first to bear the i9 moniker and utilize the new X299 (Basin Falls) chipset/motherboard. The 7900X is the fastest CPU on the market today, however, imminent competition from AMD’s 16-core, 32-thread Ryzen Threadripper CPUs and the forthcoming release of more Intel Core X series mean that its reign will be a short one. The i9-7900X supersedes the 10-core Broadwell-E core i7-6950X that held the crown for little over a year. Both are extremely powerful and pricey high end desktop processors (HEDTs) which excel in multi-threaded tasks such as media encoding. However, despite the same power draw (TDP 140W), the newer i9-7900X betters the i7-6950X in terms of peak overclocked performance by 10% mostly thanks to increased clock speeds from 3.0GHz/4.0GHz to 3.3GHz/4.3GHz for base/turbo. It also betters the i7-6950X on price by around 28%. This all translates to the i9-7900X offering around 20% more value for money, even despite its eye-watering $999 price tag. The more accessible pricing (albeit not accessible for the majority) and hurried release of the i9-7900k to market is widely perceived as a reaction to AMD’s Ryzen Threadripper CPUs, rumoured for release towards the end of July 2017. So if you want to own the fastest consumer CPU in the world, it would be wise to wait for the dust to settle. [Jul '17 CPUPro]

AMD’s 16 core, 32 thread Ryzen Threadripper 1950X is finally here to seize the throne for high end desktop processors. The 1950X is the flagship of the Zen based Threadripper series which also includes the 12 core 1920X and the 8 core 1900X. The 1950X has a stock clock of 3.4 GHz increasing to a maximum single core boost of 4.0 GHz and features quad channel DDR4 and 64 PCI Express lanes. This processor is effectively two Ryzen 7 1800Xs glued together with Infinity Fabric (AMD’s scalable interconnecting technology), making the 1950X one of the physically largest CPUs on the consumer market. If you are considering this CPU, you will need a new X399 motherboard with a TR4 socket. Early benchmarks show the 1950X competing with Intel’s similarly priced i9-7900X. Whilst the 7900X has slightly higher single and quad core scores (10%-15%), the 1950X is around 35% faster for multi-core workloads. Content creators, and other core intensive task masters will not be disappointed. [Aug '17 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.
