But I bet it means yet another new socket and another new upmarket mother board. You won't upgrade an existing machine.

every time Intel brings out a new range of processors they make sure that it means a new socket, and therefore a new mother board. I think that is reprehensible and profiteering.

I believe it is an existing server socket " Socket P (LGA 3647)"

I thought that too, but it appears to use an existing socket - the Socket 3647.....
But I bet to get full benefit of all those PICe lanes you have to go a long way up the price tree

They are saying $3000 as the cost, I haven't seen a UK price.

But there is a UK price of £9500 for a Skylake Xeon Platinum that fits in the 3647 socket.

Sounds like you could fund the fastest EYPC cpu and a newly announced workstation/server MB (4 full sized/full speed/doublewide slots) for that kind of money Maybe even a dual cpu version.

Yes it is a new socket and only one motherboard so far that uses it. The ASUS Dominus Extreme. No price yet on the board and not released yet.

However there are differences in Intel's own documentation for this processor - in a number of places they declare 68 PCIe lanes, but in others 48; in some places they say it uses a 771 socket, and yet in others it uses the 3647 socket.

Quite some beast, but Intel do need to sort out this sort of detail quickly.


(Just sorted out the PCIe lane issue - a number of lanes are shared between memory other devices, so it's 48 "real" that are shared all over the place a maximum of 68 "virtual".)

I just watched a couple of der8uer's YT videos on the cpu. One comment is that he really dislikes the socket with its 3647 pins. He said it is worst than a Threadripper or Epyc because the cpu has no mounting carrier like AMD. He said he never could get all 6 memory channels working. He would get 2, 3, 5, 4, 3, 2 etc. etc. every time he tried mounting the cpu in the socket. He finally just gave up with only 4 channels working to do his testing and benchmarking. It will overclock well with adequate cooling. He preceded onto delidding the cpu and overclocked on liquid nitrogen. Got close but didn't break the benchmarking record.

Yes, rather limited in PCIe lanes, at least compared to Threadripper which has 64 lanes with 4 going to the chipset so effectively only 60 to the slots.
