Intel Core i9-7900X
The problem is, it’s a different world now. At $1,000 for a 10-core chip, you’re paying about 100 percent over an 8-core Ryzen 7 chip for about 30 percent more performance. Even worse, we still don't know what price AMD set for its 12-core and 16-core Threadripper chips. If AMD introduces a 12-core CPU at $850, as some think, a 10-core Core i9 for $1,000 loses its appeal. For now, the Core i9-7900X reigns as the fastest consumer CPU on the planet. But it should be looking over its shoulder, as will we, for Threadripper.

Reviewers Liked

  • Workstation and productivity applications
  • Feature-packed X299 platform
  • Strong performance
  • Far easier overclocking than Haswell and Broadwell
  • 10 cores and 20 processing threads, for $700 less than last year's comparable chip

Reviewers Didn't Like

  • Performance regression in some games
  • Pricing may change when ThreadRipper arrives
  • Hot thermals
  • Software optimisations needed
  • Pricey

We walked away impressed by the speed of Intel's new Skylake-X chips when we reviewed them last week, however thermals were a severe letdown with the Core i9-7900X being too hot to handle even when paired with a premium all-in-one liquid cooler. Given...

I think we can all agree that Skylake-X offers mighty impressive performance. The Core i9-7900X blows everything else out of the water and the 7820X does a good job of making Intel's previous-generation 8-core CPU look a little sluggish.

If you're looking for a new processor and require AVX-512 vectorisation support, do a lot of video/photo editing, content creating, streaming or you have £900/$1000 to blow on a 10-core processor you probably won't get a better overall CPU than the Core...

Intel's new Core i9-7900X replaces last year's flagship, but is only the entry-level model in its category this year. Pricing is a lot better too - you can get better performance for half as much money now. If that makes this CPU seem tempting, there...

The i9-7900X is the most powerful CPU we've ever tested, and the fastest out-of-the-box consumer processor you can buy today. It also has loads of PCIe lanes which, when paired with an appropriate X299 motherboard, allows you to build a seriously...

The Core i9 7900X isn’t revolutionary. With Its multi-threading prowess would make easy prey of lessor processors and is currently the fastest desktop processor available, at least until 12 core and 14 core variants arrive.

We knew the Intel Core i9 7900X was going to be good, new Intel launches always are, but we didn't expect the gap between this processor and the previous ten core offering to be quite so wide. If you must have the absolute best then the i7-7900X is the processor for you, and so it wins our OC3D Enthusiast Award.
