Question Alder Lake Xeon Workstation Series Release Date?

Alder Lake certainly took long enough to arrive, however much further delayed by COVID. But as I want to run ECC RAM in my next desktop build, a Xeon processor and compatible motherboard are required, such these Rocket lake Xeon CPUs. https://en.wikipedia.org/wiki/Rocket_Lake#Workstation_processors

And presumably this 6 core 80 watt TDP CPU will idle cooler and draw less power than the 8 core 125 watt CPU from the same series.
https://ark.intel.com/content/www/u...w1350-processor-12m-cache-up-to-5-00-ghz.html

OR will their temps and power consumption at idle be nearly identical?

However, no where posted at the Intel website, text from their chat agents or anywhere else can I find any clue for when the Alder Lake series of Xeon workstation processors will be available.

I'm hoping those Xeon CPUs will idle even more cooler and efficiently than the Rocket Lake.

Any feedback would be appreciated.

About TDP, am I wrong or isn't a cpu with higher TDP better? If TDP means that the chip is designed to work at 125 watt maximum rather than an 80 watt maximum, then won't the 125 watt cpu generate less heat and fan noise when doing a 55 watt work load than will the 80 watt cpu?

Uh, strong statement! But you are wrong. Some examples:

a) CPU A @ 80W just performs the same as CPU B @ 125W just because A is inherently more efficient:
If that is the case, anything running @55W on CPU B would running at lower power on CPU A at ISO performance
b) CPU B has 125W TDP and CPU A has 80W TDP. However CPU B has more cores but per-core efficiency is the same between A and B
b1) The workload runs at 55W on CPU B because the workload cannot utilize all cores. Then the same holds for CPU A, which would also consume 55W at ISO performance.
b2) The workload runs at 55W on CPU B because it is power limited to 55W but otherwise utilize all cores. Then CPU A consumes more than 55W at the same performance, because it has to run at higher Voltage in order to achieve ISO performance.

So you see, 3 different outcomes

I think I’ve got it. As a related example, the 10 core 1290T and the 8 core 1390T are both 35 watts. However resource demanding video demuxing/remuxing software typically is, if it can utilize the 1290T’s all 10 cores then that CPU would be more efficient than the 8 core 1390T, the latter having to run at a higher voltage and/or run at the same voltage longer to complete the task.

No more having to use an old Cascade Lake CPU for ECC support.

Perhaps, but have fun getting DDR5 UDIMM ECC. Until recently, they were as rare as the Motherboards themselves. Alternatively, pick a DDR4 W680 Motherboard.

Expensive! I guess they believe the ZFS fans won't mind the price.

I'll reiterate it: ZFS is no more dependent on ECC than any other data-integrity checking file system. But yes, anyone who likes to avoid silent data loss should buy ECC.

Hands-on Benchmarking with Intel Sapphire Rapids Xeon Accelerators

We get hands-on with the 4th Gen Intel Xeon Scalable "Sapphire Rapids" and show some accelerator performance and discuss the future landscape

www.servethehome.com

Today, we get to show the first hands-on with the 4th Generation Intel Xeon Scalable, codenamed “Sapphire Rapids.” We are not going to get to show you everything. Intel has specifically only allowed us to show some of the acceleration performance of the new chips. Since it is going to be a few months until these officially launch

For my next PC build, which is months overdue, I was going to go with https://ark.intel.com/content/www/u...12600-processor-18m-cache-up-to-4-80-ghz.html , but there's currently no micro-ATX W680 boards supporting DDR5 RAM-only these server boards.
https://www.asrockrack.com/general/products.asp?Model=w680#AMD

And that's assuming that I would more much benefit from it than DDR4 RAM. Otherwise, this looks like the only other board. https://www.asrockind.com/en-gb/IMB-X1314

So instead, I've been holding out for the 13th gen Raptor Lake, but so far no such 65 watt base power CPUs available. https://en.wikipedia.org/wiki/Raptor_Lake#Products

We can thank Intel for this procrastinating as they insisted on competing ASAP with AMD against the AMD Ryzen 7000 series before Meteor Lake arrives. Obviously, they did so by issuing a few very fast SKUs, not any 65 watt micro-ATX ones.

How likely will they be out by mid-January? Ditto more micro-ATX W680 boards, and hopefully including at least an el cheapo audio DAC?

The 12400 was available in January after the Alder Lake launch but it was many months before the 12600 was easily available. If you want something now, your best option is to get a 13600K and power limit it to 65W in the UEFI/BIOS.
