Intel Xeon W-1300 Series "Rocket Lake" Processors Detailed
Intel has quietly let out details of its latest-generation Xeon W series workstation processors based on the 14 nm "Rocket Lake" silicon. These chips are built in the same Socket LGA1200 package as the 11th Gen Core desktop processors, but compatible with the W580 chipset. The lineup includes two 6-core/12-thread; and five 8-core/16-thread parts. Leading the pack is the Xeon W-1390P, with clock speeds of up to 5.30 GHz, followed by the W-1390, at 5.20 GHz. These two SKUs feature Thermal Velocity Boost, and are analogous with the 11th Gen Core i9 series.
Next up, are the Xeon W-1370P and W-1370, clocked at speeds of up to 5.20 GHz, and 5.10 GHz respectively, These parts lack Thermal Velocity Boost, and are comparable in many ways to the 11th Gen Core i7 SKUs. The slowest of these 8-core parts is the energy-efficient W-1390T, ticking at nominal clocks of just 1.50 GHz, with 4.90 GHz maximum boost, but a TDP of just 35 W. Among the other SKUs, the "P" SKUs have rated TDP of 125 W, while the non-P ones have 80 W. The 6-core/12-thread SKUs include the W-1350P and W-1350, clocked up to 5.10 GHz and 5.00 GHz, respectively. All Xeon W processors support up to 128 GB of dual-channel DDR4-3200 memory with ECC support.

Looking at the existing Rocket Lake stack, I am highly skeptical that this will run just at 35W at all, unless one is able to set a hard stop at 35W in the BIOS. But in doing so, you lose tremendous amount of performance with the base clock speed at a meagre 1.5 Ghz. Intel should really considering scraping the meaningless TDP since most people will not want to run their Intel chips at TDP at the expense of performance.
These will be used in large quantities by Dell, HP, Lenovo etc. for workstations.
Thanks for sharing your wisdom, apparently every other forum member knows computers are for teenagers playing games, and that RGB LEDs are not optional! :P
There are large numbers of workstation users in the professional world who don't need 4-8 channels of memory and 16+ cores, in fact very few real non-server workloads scale beyond 6-8 cores. This includes many developers, artists, system administrators, people in the financial industry etc. There are many who need reliability above anything else, where even a short downtime means lost productivity, without having any extreme mulithreaded workloads.
You should listen, then perhaps you'd learn, and be less full of bs.
There's also official ECC support, workstation/server boards and chipsets, etc.
There's numerous use cases where these are really nice entry level options.
The Ryzen chips are all "lol dual channel" too, by the way. So they've got half the memory bandwidth per core where that matters.
Also, look up what an Exchange Server license will cost you on a 64 core Threadripper vs. an 8 core anything. No, actually do that. Go on. Google it. It's not hard. You can do it. I'm not your mom, go on, Google it. There's other per core licensed software that grown ups use, too.
to get higher spd ram moduals like xmp 3600
lots of benches and marginal improvements from comet to rocket but there might be some advantages not stated clearly as apropos tic rather than toc to observe support for pcie 4.0 altogether
ex: // quake eternal, with a rx 6800 is ultra everything from gpu and raytracing on fast fast
conclusions
bought into socket 1200 with a quality board ready for rocket lake and pcie 4.0 but hey that lasted less than a season socket 1700 came out with alder and now raptor lake a real toc
