The backplane has become very sophisticated in PXIe chassis, in part because two high-quality transmission lines must be used for each full-duplex
PCIe lane. In addition, a large number of high-speed differential trigger and clock signals also are distributed, several with very tight timing restrictions.
In contrast, a
PCIe lane uses two two-wire, 2.5-GHz, low-voltage differential-signaling (LVDS) serial buses--one for each direction of traffic.
The system automatically detects Single or Dual path Gen4 drives and utilizes the
PCIe lanes accordingly.
Up to 8 cores and 16 threads, up to 5 GHz maximum turbo frequency, up to 16 MB Intel Smart Cache and up to 40 platform
PCIe lanes.
The chip has a TDP of 255W and houses a 38.5MB cache, 68
PCIe lanes (44 directly from the CPU), and a fully unlocked design for overclocking.
With up to 18 cores, 36 threads, 24.75 MB Intel Smart Cache, and up to 68 platform
PCIe lanes, Intel Core X-series processor based systems enable creators to quickly and simultaneously record, encode, edit, render and transcode.
The board also has a special mining mode that runs the
PCIe lanes at gen 1 speeds to improve stability and compatibility with riser cards.
Gibby noted that one thing he thought would help to drive HPC customers to the AMD platform would be the number of
PCIe lanes available to users in a single socket: 'We have a no-compromise, one-socket system, and what I mean by that is if you look at the way our competitor has designed its platform the
PCIe lanes are tied to the CPU, and with Sky Lake you get 48
PCIe lanes on each processor.
With up to 32 cores (64 threads), 8 memory channels and 128
PCIe lanes, AMD's EPYC processors offer flexibility, performance, and security features for today's software defined ecosystem.
