I though integer score was overall multi threaded results not a single thread. Of course an hedt platform will be slow on single core. How did you guys figure out that this integer scprebis for single threaded?

Just like old westmere Xeons, these chips will have huge overclock potential. By limiting the number of cores being overclocked, i hope they will exceed 5gHZ.

if we use a benchmark with AVX512 the intel 12 core will be better than a 24 core AMD...
No - it will be 1:1 to Zen3, and slower than Zen4 (who exist only in non-Treadripper parts)

24 core AMD (5965WX, Zen3):
Extended Instructions66,924 Million Matrices/Sec

32 core AMD (5975WX, Zen3):
Extended Instructions81,382 Million Matrices/Sec


36core Intel Xeon (w9-3475X, "~12Gen" P cores):
Extended Instructions84,679 Million Matrices/Sec



some code is best matching for Zen, some better for Intel.
True, and I love the Passmark balance here - you can read everything from it, depend if you need a workstation or a server CPU, compiling or rendering (nowadays AVX512 not needed - GPU is doing this work better) machines.

Integer score or floating point score is a multithread only.
single core probably have same/similar tests running just on 1 core.

Of course an hedr platform will be slow on single core.
2012 to 2020 November (Release of Ryzen 5000), it was like this.

all Xeons starting form Westmere up to ~10gen i9 for large socket (2011/2011v3/2066 and 36xx- don't remember no sense to buy any CPU for this socket, too slow) was able to compete 1:1 with fastest gaming CPU's (intel and AMD). First shock was Ryzen 5000, 50% faster (single thread) than any Xeon after overclocking and any gaming i9. Then 12gen intel ~80% faster than any Xeon (single thread).

4189 - this was the first nonsense socket
4677 - I hope this one will return to the "old times" when Xeon can coopete with gaming i9

Just like old westmere Xeons, these chips will have huge overclock potential. By limiting the number of cores being overclocked, i hope they will exceed 5gHZ.
if this is exactly same core like in the 12gen i9, then ~5.5GHz can be possible.

what we can guess here is the "glue" between chips is not working as expected, it's like 1650 "v0/v1" (succesor of the Westmere Xeons) very very good up to 4 cores, 6 cores too slow (1650v2 was good up to 8 when having - 15cores in E7 also slow ;) ).

Westmere: my favorite was: 1650 v2 and 1680 v2, and.. 1660 v3, 1660 v3 overclocked (to ~5GHz) you can still use today if not doing crazy things, 3years ago it was one (especially the 10,12,14 v3 core parts single socket unlocked) of the fastest HEDT workstations.

ok - 100% right, with the second result it is much better.
PassMark - Intel Xeon w9-3475X - Price performance comparison
now it's better:
65891 -> 70850
3678 -> 3725

if they (passmark) do just average of the all results, the second result is quite high:

2*70850-65891 = 75809 passmarks
2*3725-3678= 3772 single core
There's a passmark entry for a w7-2495X as well which is hitting 3878 single core and 58957 multicore.
I'd image the w9-3475x would fall in line with those numbers more, perhaps the same single core score with a multicore score of 88435-chiplet communication latency overhead.
golden cover cores are no joke, they'll handily beat zen3.

ok almost 3900 points sound really good (@4.8GHz) :) closer to the Intel 12gen, than Ryzen 5000 - ok this is probably it - i9 with proper number of pcie lanes

On the other forum there is a member who actually got there hands on a w9-3495X and is posting benchmarks. They're only getting 647 points on cpu-z's single threaded benchmark which doesn't seem 100% optimized. I suspect Windows isn't handling frequency ramping properly at this point which might explain why some of the non-overclocker benchmarks out in the wild seem underwhelming.

think what other cores do while the benchmark runs. the thread moves over cores, does not stay at one.
benchmarks under windows OS is the worst idea you can do.

Newegg is now selling the W-3400 SPR-WS CPUs, and they aren't price gouging like every other online retailer.
They are unlisted on newegg so you'll have to use a separate search engine to get to their page.

yup, that's the way.
In my excitement I made it sound like newegg was selling all the w-3400 processors, they were actually only selling the w5-3435x and w7-3465x processors. the w5 is now sold out.

I know most of us are in the "build" camp, but for work I always check OEM for a benchmark.

Supermicro, Dell and HP have their workstation configurators live. Supermicro has a watercooling option, the others look like air only.

SYS-551A-T | Full-Tower | SuperServer | Products | Supermicro

HP Z8 Fury Desktop Workstation – Configurations

Dell Precision 7960 Tower Workstation - Dell Workstations | Dell USA

HP and Dell have the silly list pricing then give discounts. For the 3435X, 128GB system I am looking at, out the door pricing is ~$5.5-$6k (aftermarket RAM on Dell and HP) with 3 year warranty, no GPU.

maybe off topic here:
i am using Kingston FURY Renegade Pro DDR5-5600 ( KF556R36RB-16 ) in my X13SEI-F with QYFQ ES2 processor without any issue.
the KF556R36RB-16 isworking with the JEDEC profile - 4800Mt 1.1V
of course i can not use the XMP profiles with the X13SEI motherboard but if i can get a W790 motherboard i still have overclockable RDIMMs.
the KF560R32RB-16 DDR5-6000 is the better one but was not cheap as the 5600 ones(got them for 75EUR each)

Are they overclockable? It still seems cheaper to get the MB, CPU and use my existing chassis, cooling and power supply. Not to mention propriety HP and Dell stuff.

Unknown - waiting on some 3rd party reviews and hopefully core scaling (watts vs MHz vs temps) data. Lead times were a few weeks on at least some of these, so I suspect not many in the wild yet.

I built out a potential rackmount BOM for an overclockable DIY and it came to $4600:

My application would benefit greatly from keeping multi core clocks high, so this is an interest of mine. Only data I have found so far is this Skatterbencher piece: https://skatterbencher.com/2023/03/29/skatterbencher-59-intel-xeon-w7-2495x-overclocked-to-5200-mhz/

He uses the 4 channel Asus board, the Ace, not the Sage.

Pretty much need watercooling to do anything sustained with these Alder Lake cores - with OC they exceed 300W and climb to 500W quickly; Supermicro is the only OEM with that as an option of the 3 above.

I am on mobile so I will keep this relatively short.

This article in AEC magazine has some good in-depth performance and behavior numbers.

As feared and expected the CPU frequency/scaling performance is pretty abysmal as more cores are engaged.

Without overclocking and therefore watercooling this will not be competitive for my application.

Intel Xeon ‘Sapphire Rapids’ versus AMD Ryzen Threadripper Pro - AEC Magazine

That said, they also link to a UK custom box maker (that uses watercooling and OC) that also rents cloud bare metal installs by the week. May be worth testing on one.

Hi all. tell me Pro WS W790E-SAGE SE board

I connected and configured everything in the BIOS, I turned on the bmc remote, but I can’t get into it. ip 192.168.1.13 it pings in windows but I can’t get to the console through the browser, what could be the problem? and even in the BIOS, the battery voltage shows 1.6v and the red light is on, is this item normal?
