AMD Ryzen Threadripper PRO 7995WX Emerges: 96 Cores, DDR5 Memory, and Over 5.0 GHz Boost Frequency

The only problem with this logic is that even though modern platforms support bifurcation, devices are still restricted to their generational bandwidth.

A bifurcated Gen 5 x4 link with a Gen 3 device will still result in a Gen 3 x2 + whatever x2 link; and performance on existing devices will still degrade. Which is why this is less optimal than having a healthy supply of physical lanes available, something that is not even on advanced creator motherboards such as my MSI MEG Z690 ACE.

Note the liberal use of up to, for example, M2_4 slot bandwidth is shared with PCIE_3, x2 each or x4 fully directed to each slot, disabling the other. There's simply not enough resources in the system to enable all ports at once.

Yeah I had the issue with a SATA addon card, the original one was a 2nd gen x1 lane card. Sticking it in a x4 or x16 slot doesnt matter its a x1 card.. Replaced it with a 3rd gen x1 card. Although had to use a x4/x16 slot as all the x1 slots on the board are gen 2, only the two CPU routed slots are Gen 3 (b450 pro 4).

That still doesn't avoid the fact that if the main link is x8, it can only bifurcate into four x2 links, which would still reduce the SSD's maximum performance and incur the generational penalty to older devices. So we're back to square one, it's either two x4 or four x2, and there's no way to work around that unless a x16 link to the chipset or CPU is available

Something I saw the other day there is an Asus GPU that runs at 8x but it also has 1 (or 2?) NVMe connectors so you can avoid wasting the unused lanes in the primary x16 slot. That's pretty nice feature for x8 cards.

That's quite situational, though. Zen 3 lacks Zen 4/SPR's advanced AVX-512 instructions entirely, which may very well matter to the target market (primarily VFX and renderfarms). Again keeping in mind that these aren't server chips so benching them as servers is counterproductive (there is Epyc for that).

Zen 3 doesn't have AVX 512
Zen 4 has AVX 512, it's just dual 256 bit AVX fuse & combined
it's slower than intel's because of synchronization of FPU's clocks.

Are there any measurements of this?

Yes in AVX-512 workload AMD ZEN 4 seems beat Intel in opposite that the colleague write?

Exactly. I saw similar measurements of server CPUs by Phoronix.

So, was the member DemonicRyzen having a mental fart?

 

[Dr. Dro]

Yeah Zen 4 is actually king at -512 afaik. Raptor doesn't support it, so that need not apply

 

[QUANTUMPHYSICS]

I'm guessing if you buy this, you don't need a new CPU till Skynet becomes self aware?

It's overkill for gaming, but it's the ultimate CPU for the time being. I doubt Intel will be putting out a 96 core CPU anytime soon.

With Granite Rapids next year, Intel might release Xeon 6 with higher core count. We need to wait and see, as they are rumoured to have server designs with up to 120 cores.

Why are you comparing a Laptop AVX-512 to Threadripper pro?
Tigerlake was laptop only & it's really old so beating that isn't something to brag about when it's 10th & 11th Gen Intel laptops from 5-6 years ago.

The reason is that there is no way to compare with future processors yet. Extrapolation from the results of the now available Ryzen 7000 and Epyc, I am not able to do, and I am not sure if it is correct. So, I showed what I had discovered at that point.

There is no other Intel product, apart from Xeons, that currently support 512.
You show us Xeon vs. EPYC 512 performance comparison. Can you?

Good night Intel.

How much is intel's market share? 80% or still 90%?

So, the two groups of tests show that:
1. use of AVX-512 on EPYC Genoa led to 35% increase in performance in various workloads (December article)
2. use of AVX-512 on EPYC Genoa led to 21% increase in performance in various workloads (January article)
3. use of AVX-512 on Xeon SPR led to 44% increase in performance in various workloads (January article)
So, Xeon Gen4 seems to be 9-23% faster with AVX-512 depending on which group of tests are used.
'Free' performance boost for Xeons looks good.

How much is intel's market share? 80% or still 90%?

It depends on market research company you ask, but it does look like it's soon going to be less than 70%.
