short answer: 1600MHz
If remember correctly (now using Lenovo 8x 8894v4 - and thinking about TR7000 single CPU, overclocked ;) ):
G8 (DDR3) with v2 CPU's: was always max of 1600MHz (and 1866MHz in the mode that you have not 8 channels(4 SMI channels) but 4).
G9 (DDR4) with v4 CPU's: was always...
Talking about "true" ECC DIMMs ?
EDIT: DDR5 unbuffered and DDR5 registered is different.
DDR3 and DDR3 ECC can work on same motherboards (LGA1366/2011/some 2011-v3) and CPU (for example E5-2678 V3).
DDR4 and DDR4 ECC can work on same motherboards (LGA 2011-v3/3647/...) and CPU (for example...
ok - 100% right, with the second result it is much better.
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...
Integer score or floating point score is a multithread only.
single core probably have same/similar tests running just on 1 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-...
No - it will be 1:1 to Zen3, and slower than Zen4 (who exist only in non-Treadripper parts)
24 core AMD (5965WX, Zen3):
66,924 Million Matrices/Sec
32 core AMD (5975WX, Zen3):
81,382 Million Matrices/Sec
36core Intel Xeon (w9-3475X...
Yes, this is a bad thing :/ slow in multi-core
Good thing is it finally the fastest single core performance CPU (still like Ryzen 5900X) with massive number of PCIe lanes.
so in short... maybe fast enough to build ZFS NAS based on NVMe PCIe 4.0 who can saturate 2x 100GbE when copy 1 large...
first results of the Intel Xeon w9-3475X - slightly slower than predicted
Intel Xeon w9-3475X - 65891 points!
Single Thread Rating: 3678
AMD Ryzen Threadripper PRO 5995WX - 96892...
Yes, but I don't recommend PCIe x8 for 2x100G, because exactly like Freebsd1976 wrote it will be about 80GbE (display as 100GbE link of course), what is not super bad for 40GbE replacement but it's not true 100GbE.
for 2x100GbE PCIe 3.0 x16 is also too slow (will do "160GbE") first good...
on ConnectX-3 working @ 40GbE i was able to saturate the link on samba under windows, 4.42GB/s.
I didnt try this @ 56GbE but should be faster.
I see right now pcie x8 for $100 and x16 for $159. (50GbE variant need to flash to 100GbE)
I was using for a short while Cosco 3164Q (backthen cost about 1000 EUR) but switched to much faster (and cheaper) Celestica 100GbE -but less ports, and Mellanox 56GbE.
i am using:
ConnectX-3 for 40G
ConnectX-4 for 100G only
ConnectX-5 for 2x100G only
and having experimental 200G but no...
I think even cheaper bought 6 switches for about 380-460 usd, all working good (with fixed atom cpu)
Plus cards (required flash to work as 100GbE) for 100-120 EUR but long time ago, plus big transcievers box for about $8each.
Now maybe 400GbE will be possible somehow, and pcie 4.0/5.0 ;)
sounds you have the proper cable to do 56GbE instead of 40GbE,
when you turn off autoneg on Linux and set to 56000 (and advertised speed too) windows should connect at 56GbE and display the speed in driver and connection window.
btw. my max speed file transfer on Connext3 using 40GbE was...
For gaming any modern Epyc and (almost) all TR's are fast enough, some E7v4 is still fine too together with old 1650v2 (after overclocking) - tested recently email@example.com + 64GB + GF3090, still ok.
Fully agree they are slow in single core tasks.
(almost) For sure new Xeons will crush all...
Wow - they look really promising! Don't have access to any of them right now so can guess. A quick math.
P cores inside new W9 is much faster than Zen3 and slightly faster than Zen4 (almost identical)
My guess is (4.8GHz models): ~3950 Passmark in the single core (5995wx - 3302pt, Epyc Genoa...
Good document, I also recommend this one:
Optimizing Memory Performance of Lenovo Servers Based on Intel Xeon E7 v3 Processors
and my opinion about SMI 2666/3200 is the same, no sense to use other memory modes, so this is max for this platforms
Ok so probably no chances to use CB194 as a 40/56/100GbE cards (without internal Mellanox SDK for mt4113 chip).
What is maybe possible to make, is:
CB194a as a IB and do ~110GbE via EoIB (dual port and x16 PCIe 3.0)
so few CB194a cards for $17 + ~$200 IB switch ;)
probably don't make any...
