I’m more interested in the Xeon W-1260P, which seems to be an i9-10900K with ECC enabled. It should work very well for my engineering software (which uses Intel math libraries that are slow on AMD). Hopefully they come out with it soon.
- jeffbee 6y agoThanks 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.
- lliamander 6y agoThose 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.
- madengr 6y agoW480 is still PCIE 3.0, from what I have read. I’ll probably end up getting one of these: https://www.asus.com/uk/Motherboards/Pro-WS-W480-ACE/ https://www.asus.com/uk/Motherboards/Pro-WS-W480-ACE/
- lliamander 6y agoNice. What interests you about these Xeon CPUs specifically?
- madengr 6y agoThe 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).
- lliamander 6y agoCool, thanks for sharing.
- vbezhenar 6y agoAccording to [0] it has 16 lanes. They probably are counting chipset lanes which are fake lanes. 0: https://ark.intel.com/content/www/us/en/ark/products/199336/intel-xeon-w-1290p-processor-20m-cache-3-70-ghz.html https://ark.intel.com/content/www/us/en/ark/products/199336/...
- lliamander 6y agoAh, I see. Their marketing material referred to "total platform lanes"[0]. That's less helpful. [0] https://www.servethehome.com/wp-content/uploads/2020/05/Intel-Xeon-W-1200-Series-SKU-Stack.jpg https://www.servethehome.com/wp-content/uploads/2020/05/Inte...
- jeffbee 6y agoIf 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.
- lliamander 6y agoOh certainly. 16 CPU lanes is perfectly reasonable. I just feel somewhat misled by the marketing material.
