| | | Intel is trying to delay PCIe, (Peripheral Component Interconnect Express), Gen4 support, and has not announced if, and when, PCIe Gen4 will be supported on Intel processors.
This stands in contradiction to IBM, for example, who announced a long time ago that the two large Coral Project clusters, which will be built in collaboration with Mellanox and Nvidia in late 2017, will use Power(9) CPU's, and will support PCIe Gen4.
(The data rate of PCIe Gen4 is 16Gb/s per lane, which is double the data rate of the current PCIe Gen3).
My belief - Intel is doing this in an attempt to slow down Mellanox, and others, with the next generation 200Gb/s networking which requires PCIe Gen4 to utilize the 200Gb/s bandwidth.
It is, therefore, not very surprising Intel does not want to join the CCIX consortium which is based on PCIe either -
Why so ? Because Intel's current CEO policy is to fight, and compete, with pretty much all of the other companies listed rather than to collaborate with them...
I do believe that once IBM, and perhaps AMD and also ARM, will actually release a CPU which will support PCIe Gen4, Intel will then release its own CPU's which support it as well, as Intel cannot really allow themselves to be considered with a CPU technology which is a generation behind !
Further, Intel most likely already has internal plans for this, which they have not publicized, yet in an attempt to slow down Mellanox, IBM, and the remainder of the CCIX consortium.
What is actually most surprising about the CCIX consortium is that Nvidia has not joined in spite of Mellanox and IBM - its closest allies, and being a central part of the CCIX.
This is lost on me to an extent, however, this may have to do with AMD - Nvidia's biggest GPU competitor being part of the CCIX consortium.
Supposition and conjecture all aside, Nvidia may still join the CCIX consortium.
Hope this explains things a bit. |
