Intel Skylake architecture server CPU exposure does not rise in this configuration

Intel, which has dominated the PC market for many years, is actually more powerful in the server market where the average consumer rarely pays attention. Previously, they had publicly stated that the company currently has a market share of 99% of the server. Whether it is the AMD or ARM camps, it will not be possible to shake Intel's dominance in a short period of time. Behind Intelâ€™s backing is the companyâ€™s proud Xeon series of server CPUs. Now, a new server CPU product based on Intel's most advanced Skylake architecture has been officially exposed by the media.

The Skylake architecture was officially launched in August 2015 and is considered to be the successor to Intel's Haswell architecture and Broadwell architecture. At the same time, there were two desktop-class processors, the Intel Core i7-6700K and i5-6600K based on the Skylake architecture. Recently, according to the exposure of India's import and export website, this architecture will soon be logged into Intel's server-class products.

The Skylake architecture server CPU exposed, the high-profile version has 28 cores and 56 threads. The single-core frequency is 1.8GHz. The interface uses Socket P in the LGA3647 package. It supports six channels of DDR4 memory, three QPI buses, and 48 PCI-E 3.0 channels. Thermal design power consumption is 165W.

In addition to the above-mentioned predictable updates, the new series is somewhat anomalous in its cache capacity. Previously, Intel server chips mostly follow the design of 2.5MB cache per core, such as Broadwell architecture with up to 24 threads and a cache capacity of 60MB. While the Skylake architecture series that was exposed this time increased the core count to 28, but the cache capacity was reduced to 38.5MB, which means that there is only 1.375MB cache per core, which is much lower than the current level - usually, the server chip cache The larger the capacity, the stronger the performance, but the cache also occupies a large chip area and is a double-edged sword.

If it is not a website error, then the cache reduction of the new product is likely to be because Skylake's new architecture changes the traditional cache design, eliminating the need for a huge cache capacity, or reducing the cache from 60MB to 38MB, the performance can not be not Affected.

Considering that Intel released the new server CPU of Broadwell architecture a few months ago, the Skylake exposure will not be available until at least the middle of next year. Not surprisingly, next year will encounter AMD's 32-core Naples processor, the two sides will start a battle in the high-performance server market.
