Question What is the difference between the Intel Xeon Platinum 8160 and the 8160T ?

[Sudecka80]

Picked up a Lenovo ThinkStation P720 (30BB)...
"hooked" onto the dual NVMe slots, and RAID (HA! not really)
Came with single Xeon Silver 4110 (85W) (Lenovo OEM price: 800 bucks!! for second 4110.... nah... might as well as go a little better)
Installed 6@ DDR4 2666 RDIMMs (192GB)
replaced 690W PSU with 900W
Next:
Upgraded to 2@ Xeon Gold 6148 (150W)...
added extra 6@ DDR 2666 RDIMMs(192GB), and second CPU cooler
(Lenovo OEM price for 6148: over 1000 bones a pop!!)
Added MSI RTX 3070... a beast, and space hog. (moved to T/S P520, along with 900W PSU)
All are FCLGA3647 Socket (aka"P")
Installed RTX A4000 in P720 (single-slot GPU)
So far, so good...
Xeon Platinum 8160 is the limit forP720 (also compatible with on-hand 2666 RDIMMs)
Lenovo on-line Parts lists Platinum 8160T
8160"T" is 3 to 4 times the going price for for new 8160 on the general market
Asked Lenovo whats the difference? Lenovo: "ask Intel" (not an unreasonable response)
Asked Intel (something akin to writing a politician): Intel:"Ask Lenovo"
So.... the 8160T "is engineered for longevity"- Intel response (runs cooler??)
vs. the non-"T" 8160??
According to Intel published documentation: 8160 and 8160T are the same; except that the 8160T runs cooler.
Can an 8160T be used to replace 8160? both are listed as 150W
OR, vice-versa? (in my case, 8160 taking the place of the 8160t/6148)
Talking to Noctua regarding after-market cooling solutions.
IF 8160T runs cooler (slower), is that something determined by Lenovo BIOS?
8160 CPUs showed up today. (might test with Lenovo OEM Coolers??... CPU 0 150W, CPU 1, 205W)
Thanks for any useful information,
John

According to Intel published data: 8160 and 8160T are the same; except that the 8160T rubs cooler.

on the contrary, they are both identical except for two fields, their Tcase temps, meaning the T variant can run at a higher temperature = higher endurance scenarios as well as Embedded Options.

This would be worth a read;

"Embedded Options Available" what does it mean in a processor????

So, (line 28, of Intel .xls document) the "T" version is "Embedded Options = YES" (vs. "NO" for non-"T" version)
performance dictated by Lenovo Mobo settings (Chipset/BIOS?) i.e. "throttles down" 8160... Still an improvement over 6148.
...will run Passmark, just for fun
(hopefully, CPU overheat warning will alert, before the mushroom cloud)

oops, got it upside-down (frontal lobes turning to mush from bangin' my head against the wall... (former 486 "gearhead"... yup, been there since GWBASIC on smelly rolls of yellow punched paper tape/ and 3.1.1... and buying 256K RAM "caterpillars" from plastic tubes... tactical USAF computers, using ferrite-core memory... just bang it on the bench to "zero"),
...my bad

The "T" suffix processors are lower power versions of the underlying processor.
They are used on motherboards that can not handle the higher power processors.
Or, on products that have limited heat dissipation capability.

I would think that a T version would work fine, just at a lower performance level.

 

[Sudecka80]

The "T" version is already listed as OEM by Lenovo online parts listing: ("...it should work fine")
Actually asking about the reverse:
Will my P720 tolerate the "NON-T" version? (i.e. Xeon Platinum 8160)
or, will the Non-T 8160 tolerate the P720 environment? (will additional cooling be required?)

It should accommodate it if it will do so with the T version.

Thank you!
trying to avoid a small mushroom cloud...
Spent way too much time trying to make a silk purse from a sows' ear

Let us know how this all turns out. Good luck.

After extensive back-and-forth with The great folks at Noctua, they real weren't very comfortable with a guaranteed solution; offered several solutions due to the myriad layouts of different manufacturers.
That said, came to the conclusion that the OEM 150W/205W coolers "should" be sufficient;
So far, no smoke! CPUs appear to stay within parameters (50 - 60C).
Another "trick": rear housing fan originally set up to exhaust out; reinstalled "reversed" (i.e. blowing in over CPU units... also, with ODD frame/housing removed, fabricated a front panel for a spare fan to exhaust out... keeping the airflow in one direction (i.e. Back to front)

BTW, Finished installing ASUS Hyper M2 x16 Gen 4 "quad M.2 NVMe"; filled with 4x Samsung 990PRO 2TB...
Intel VROCSSDMOD VROC key...Raid 10 setup 3539.7GB... sound about right?
