Ars Technica article — Intel unveils X-series platform: Up to 18 cores and 36 threads, from $242 to $2,000

The Intel platform, consisting of the new X299 chipset and new X-series processors, will go all the way up to 18 cores and 36 threads. The HEDT segment is aimed at gamers, video streamers, and content creators with deep pockets or an insatiable desire for more concurrent threads than the mainstream processor segment has to offer. The value proposition for this segment is always a little skewed, with the chips being as much prestige parts as anything else. Straightforward gaming workloads may struggled to make full use of the chips’ resources, but serious Twitch streamers, for example, can make good use of the extra cores. Software developers are another group that can make good use of all those cores.

The new platform has wider range and greater complexity than the X99 platform it replaces. At the low end are “Kaby Lake-X” processors: the i5-7640X and the i7-7740X. These chips are very similar to the existing mainstream Kaby Lake processors that came to market earlier this year; four cores with either four (for the i5) or eight (for the i7) threads, two memory channels, and 16 PCIe 3 lanes from the CPU itself. The chips have a higher power envelope—up to 112W, instead of the 91W of non-X parts—and use X299’s new Socket 2066. Their clock speeds are a little higher, too; the $339 i7-7740X has a base clock of 4.3GHz and a turbo of 4.5GHz, compared to the 4.2/4.5GHz of the $339 i7-7700K.

The Skylake-X chips will also expand Intel’s numbering system: Intel is adding a new i9 branding that slots in above the i7 branding for the high-end processors.  As is Intel’s wont, the Skylake X range will suffer certain kinds of segmentation. The cheapest Skylake X part, the $389 six core, 12 thread i7-7800X, won’t include Turbo Boost Max 3 and will only officially support 2400MHz memory. Both that processor and the next highest, the $599 eight-core, 16-thread i7-7820X, will have only 28 PCIe 3 lanes, though this part will support memory speeds up to 2666MHz. It’s not until the $999 10-core, 20-thread i9-7900X that the full range of features is lit up: 44 PCIe lanes, Turbo Boost Max 3, and 2666MHz memory. These three parts will all have a 140W power envelope.
