Hardware Intel 28 core Xeon Skylake LGA-3467 Processors !

eva2000 · Jun 21, 2015

Intel is moving further and further ahead of AMD in server processor market with Intel 28 core Xeon Skylake LGA-3467 processor on Intel platform code-named "Purley" scheduled for rollout in 2017.

28 cores/56 threads over 8 socket platform = 224 cores / 448 cpu threads ! And 6TB per socket x 8 = 48TB of memory !

The platform will support dual-socket (2S), quad-socket (4S) as well as octa-socket (8S) machines and will rely on Intel’s next-generation a point-to-point processor interconnect UPI (Ultra Path Interconnect) bus, which will replace the company’s current-gen QuickPath Interconnect (QPI) technology.

At present, not a lot is known about Intel’s next-generation UltraPath Interconnect (UPI) technology (also known as KTI or Keizer Technology Interconnect), except the fact that it will operate at 9.6GT/s or 10.4GT/s data-rates and will be considerably more efficient than today’s QPI since it will support multiple requests per message.

The “Purley” server platform will be the first to support six-channel memory per socket, which will provide massive amount of bandwidth to each processor. Besides, the new platform will also be the first to support Intel’s OmniPath 100Gb/s fabric to connect for external compute and I/O nodes, which will greatly increase performance in supercomputer applications.

Intel Xeon “Skylake”: 28 cores, 6-channel DDR4 memory, Omni-Path fabric

Intel will release three different versions of Xeon processors for its “Purley” platform targeting different applications two years from now – “Skylake-EP”, “Skylake-EX” and “Skylake-F” – according to a report from CPU World. The new chips will feature up to 28 cores based on the “Skylake” micro-architecture with AVX512 instructions and Hyper-Transport technology, up to six DDR4 memory channels (up to two 2400MHz DIMMs per channel are supported, i.e., up to 768GB of DDR4 memory per socket without SMB), up to 48 PCI Express 3.0 lanes as well as two or three UPI channels per socket.

Intel Xeon “Skylake-EP” processors will be aimed at mainstream dual-socket (2S) servers and will thus only have two UPI links. Thermal design power of low-power versions of such processors will range from 45W to 80W, whereas standard high-performance offerings will have TDP of up to 145W. Workstation-class offerings with increased clock-rates will be rated to dissipate up to 160W.

Intel Xeon “Skylake-EX” processors will be designed for high-performance and mission critical machines with two, four or even eight sockets, which means that they will feature up to three UPI links. The processors will introduce new RAS [reliability, availability, serviceability] features such as Instruction Retry (pipeline error protection for integers), Advanced Error Detection and Correction as well as Adaptive Dual Device Data Correction, to make next-gen high-end servers even more robust. According to previously released unofficial information, Intel’s forthcoming expandable processors will support four times higher memory capacity (compared to today’s chips) thanks to “Apache Pass” scalable memory buffer (SMB), which means up to 6144GB (over 6TB) per socket, or up to 24576GB of DDR4 RAM per 4S machine. The “Skylake-EX” chips will have TDP of up to 165W.

Intel Xeon “Skylake-F” will be aimed at high-performance computing applications (which use 2S platforms) and will incorporate one link of the first-generation OmniPath fabric with 100Gb/s bandwidth. The latter will be supported by the code-named “Storm Lake” chip, which will be incorporated into the Xeon’s multi-chip-module (MCM) package. Among other things, Omni-Path Fabric will be used to connect to next-gen Xeon Phi co-processors.

Thanks to massively higher memory bandwidth, increased core count, improved micro-architecture and 512-bit AVX-3.* instructions, expect Intel Xeon “Skylake” processors to offer dramatically higher performance compared to today’s central processing units for servers. The architecture of the processors will be configurable, hence, Intel will easily tailor it for custom solutions required by its large cloud datacentre clients. Moreover, the new processors are expected to integrate “Cannonlake” graphics cores and media transcode capabilities, at least, optionally.

looks like encryption performance has a big boost too

The new QuickAssist accelerator is expected to provide substantially improved acceleration performance: up to 2.5x faster decryption, and up to 4x better compression speed compared to “Coleto Creek” chip used today.

yeah me neither.. we can only dream or hope some cloud/vps providers move to such Intel Xeon Skylake based processors
