Intel Xeon Platinum and Gold Series Models and Details Released

While Intel’s desktop and laptop processors are using the latest generation Kaby Lake core, the multi-socket high-end Xeon processors, used in servers and workstations, are still using the much older Broadwell core. The full range is due to be refreshed soon, with a whole range of new chips using a derivative of the Skylake core. There’s still not much known about these long-awaited processors, butIntel has let slip one thing: an all-new naming scheme.Intel Xeon Platinum and Intel Xeon Gold series.

We do expect to see product differentiation based on the level. First,the new naming, which Intel has disclosed in a change notification document (spotted by Computerbase), appears to discard this scheme entirely. At the top are 14 processors branded “Xeon Platinum” at base speeds from 2.0 to 3.6GHz and 8000-series model numbers. These are presumed to be counterparts to the current E7 range. Exact socket and core counts remain unknown. Most of the Platinum series is expected to offer between 22 and 28 cores, with the exception of the 3.6GHz part; this will use the same design, but with far fewer cores enabled, to offer a high cache, high-clock option.

 

Below the Platinum parts are 20 “Gold” brand chips, with base clock speeds from 2.0GHz to 3.6GHz. All of these are listed with a 6000-series model number except one with a 5000-series number. This suggests, if nothing else, that the lead digit of the model number no longer denotes the number of supported sockets. Core counts for the Gold parts are believed to be in the 14-22 range, though again there will be a high-clock, high-cache, low-core version.

 

Both Gold and Platinum chips will also include variants with a T and M suffix. The T suffix has been used before to indicate a low power version; the M suffix has traditionally implied a mobile part, but its meaning here is unknown.

 

The Gold and Platinum processors are both using a Skylake variant called Skylake-SP. This will include features not found in the regular desktop and mobile Skylake processors, most notably the inclusion of AVX512. AVX512 extends the existing 256-bit AVX vector instructions to be twice as wide. Intel is also developing a variant known as Skylake-X, along with a Key Lake variant named Kay Lake-X.are likely to have consumer-oriented versions when Intel refreshes its high-end desktop processors.
