Intel Launches Xeon Scalable CPUs: Dual Xeon Platinum 8176, 112 Threads Tested (hothardware.com)

MojoKid writes: Intel announced its new Xeon Scalable processor family based on the 14nm Skylake-SP microarchitecture a few weeks back, though today marks the official launch of the platform. Not only do these processors feature a new microarchitecture, but Intel has also revamped the naming convention and arrangement of the Xeon product stack, branding them with Platinum, Gold, Silver, and Bronze model families. Intel Xeon Scalable series processors feature core counts ranging from 4 to 28, with varied frequencies and cache configurations. Workstation processors and lower-core count server chips top out in the 3.2GHz -- 3.6GHz range, while the higher-core count products typically fall in the 2GHz -- 2.7GHz range. Six memory channels are supported and the chips have 48 lanes of integrated PCIe 3.0 connectivity. Power envelopes range all the way from 70W on up to 205W. The Xeon Scalable series also introduces new security, virtualization, and storage-related features, more memory bandwidth, support for AVX-512 extensions, a mesh interconnect, and enhanced hardware controlled power management, among a host of other architectural improvements. Testing of a 2P Xeon Platinum 8176 system, sporting 56 physical cores / 112 threads shows significantly increased performance and bandwidth, with only moderately higher power consumption versus a previous-gen 2P Xeon E5-2679 v4-based system.

    Very expensive (the top one is $11722) and very fragmented portfolio. There actually is a review comparing one of the top Xeon Platinums 8176 ($8719) to the AMD EPYC 7601 (4200$) - http://www.anandtech.com/show/11544/intel-skylake-ep-vs-amd-epyc-7000-cpu-battle-of-the-decade

    The results might be surprising and speak of desperation in pushing the Core-derived architectures too far. Another indicator is the recent HEDT platform's problems on Tom's Hardware - http://www.tomshardware.com/reviews/-intel-skylake-x-overclocking-thermal-issues,5117.html

    Not to mention another security nightmare on the level of Intel ME/AMT:

    "The chipset will also include a new feature called Intel’s Innovation Engine, giving a small embedded core into the PCH which mirrors Intel’s Management Engine but is designed for system-builders and integrators. This allows specialist firmware to manage some of the capabilities of the system on top of Intel’s ME, and is essentially an Intel Quark x86 core with 1.4MB SRAM."

    Because we all know the motherboard manufacturers are known for stable and secure code, so let's let them botch yet another thing.

    It's high time AMD kicked Intel's butt into actually trying and not milking their customers constantly.
