It was just a local array of RAID 10 storage, regular SATA SSDs at that, we did testing with NVMe but it wasn't that much faster, presumably because once the website loaded to RAM it didn't need to read from disk.

My current thinking is that 144 cores might indeed be the max configuration. In which case, it'll definitely receive their full LGA 7259 w/ 12-channel memory.
Hey, did you change jobs recently? Or was that web hosting gig something way in the past?

Other than that, the E-cores' FPU performance is almost commensurate with their integer performance, which is more than half as fast as a P-core. So, if you had a choice between a 144-core Sierra Forest CPU and a 72-core Granite Rapids, the SF would probably be faster at highly-scalable workloads.
I assume their main objective is to fend off the threat posed by ARM's N2 cores, and the rumored CPUs featuring like 192 of them. Then again, Intel is probably ready to do just about anything to reclaim the performance and efficiency titles from EPYC.
BTW, a big version of Sierra Forest is rumored to have more than 320 cores and 12-channel DDR5-8000. I'm guessing the 144-core model will be a single die and have only 8-channel DDR5 support.

Good point. I guess they'd go Ceph storage + high availability or something?

As others said, cloud hosts will love this, as more cores per socket has many ancillary benefits for their business.
TBH I think many Phoronix readers would glady take e-core heavy desktops/laptops for the compilation muscle.Last edited by brucethemoose; 30 March 2023, 02:33 AM.

I think it'll be popular for webhosts, cloud providers etc. They're almost entirely useless for my use cases for Xeon CPUs.

My thoughts also. Sapphire Rapids was "on course" for a summer 22 release in their 2022 investor call. Two slips later, and it landed Jan 2023.
I'll believe a new product is available when I can order it and have it arrive the same week.
