Those are pretty interesting, especially with 40 PCIE lanes.

I wonder if (like the z490) the W480 motherboards will support PCIE gen4, and whether there will be Rocket Lake Xeon W 1300 CPUs.

According to [0] it has 16 lanes. They probably are counting chipset lanes which are fake lanes.

Ah, I see. Their marketing material referred to "total platform lanes"[0]. That's less helpful.

If you want more PCIe lanes in a Xeon, you need a Cascade Lake part like the W-2275, 48 lanes and 4-channel memory, too.

Oh certainly. 16 CPU lanes is perfectly reasonable. I just feel somewhat misled by the marketing material.

W480 is still PCIE 3.0, from what I have read. I’ll probably end up getting one of these:

Nice. What interests you about these Xeon CPUs specifically?

The software I use, uses between 2 and 4 cores. I’d say 70% of the time it’s 1 core. Thus these new processors with 5.3 GHz on a single core should work well. I also have another application that can use 8, with diminishing returns past 2.

I thought I’d have to settle for the non-ECC i9-10900K, and risk memory errors for long simulations.

The Xeons have always been slow on clock speed, and high on cores. My ideal setup is a gamer PC with ECC, and this W-1290P seems to fit that.

I can’t use AMD as those Intel math libraries are 30% slower on AMD (equivalent clock and cores).

Cool, thanks for sharing.

Thanks for pointing it out. I was trying to figure out if we had to settle for the core i3-10100e if we want ECC. Apparently no. The 1290 has higher clocks than anything in this article, plus ECC.

You caught my typo. I meant W-1290P. Should be about $50 more than the i9-10900K.

$50 + a motherboard you can't buy yet.
