AMD might announce their new CPU lineup on Tuesday

[JoeCoke]

That's a lot of damage!

[GOTSpectrum]

Lets be honest, when intel dropped that 48C frankenchip we knew this was going to be big...

[Taf the Ghost]

C-Ray demo:

 

1 Socket, 64c Rome: 28.1

2 Socket, 58c Xeon Platinum: 30.2

 

QHD test, so 1440p.

 

[NumLock21]

Their stock went down even further after the demo.

leaves with "thunder" in the background

considering how dense dual socket cpus can be made, this will mean amd can provide double the performance per server 

[Tech Wizard]

Cray benchmark:

 

One socket Rome scored 28.1 seconds (air-cooled, stock, not final frequency)

Two Xeon 8180Ms scored 30.2 seconds

ineresting note that dual socket cascade lake wouldnt compare to good to this either

So is it really a 7nm processor if it still has 14nm components?

[pas008]

having the memory controller separate can relieve the memory speed dependency on ryzen?

If you read our AMD EPYC or Intel Xeon benchmarks, we often use c-ray, and have been doing so for years. C-ray is an extremely favorable benchmark for AMD’s Zen architectures over Intel Xeon architectures. Please keep that in mind. Still, this is an impressive result!

Just as a way of note.

with extra avx performance and the 7nm class power consumption, intel is in trouble, i bet this might explain at least partly why epyc 1 wasn't selling as much as expected, i would totally wait a half a year to get 2 times the performance

Yes. Moving things off-die doesn't mean it's no longer a CPU. Otherwise you could probably argue that they weren't really CPUs when the Northbridge was still off-die. This is simply multi die.

Besides, Intel is working on the same thing.

Lisa actually mentioned it. I/O doesn't scale down. It's why everyone has been looking at Chiplets for so long. Most of the die could probably be done at 22nm without issue, if AMD had access to a fab with it. But, to save even more money, they can reuse their designs from Zen1 without much issue, plus iterations upon that work.

Most of the reasons why companies are pursuing chiplet technology is more for the cost savings going modular.

 

I don't see a reason why I/O doesn't scale down that makes it extraordinarily hard to shrink it when the CPUs are doing just fine. If anything it looks more like they're opting to use a larger node size because it's a mature manufacturing process and the part doesn't really need the benefits a smaller transistor size would provide.

I think they mean it doesnt really help performance all that much if they did shrink it

Most of the I/O doesn't gain anything from the shrink, so it takes up space and increases failures in the manufacturing process. It is amazing to see it actually at the production level. It's really quite something.

 

In other news, I'm guessing Milan (Zen3) won't have DDR5. Unless the Milan I/O die is getting both DDR4 & DDR5 controllers. That socket compatibility aspect really has surprised me, but I guess AMD expects a lot of the market to not need all of the PCIe lanes and 4.0 lanes require different trace approaches.

All it would do is lower the power consumption. If it's low enough already, then there's probably no point in spending the money to get those dies shrunk.

Yup. Plus, Chiplets really help total frequency, yield and Time-to-market.

 

Thinking about the Chiplet approach, now that we can see it, AMD can run their entire product stack by simply making different 14nm parts. Looks pretty straight forward how they're going to manage the WSA now, haha.

AMD Announces 64-Core 7nm Rome CPUs, 7nm MI60 GPUs, And Zen 4. 

"If AMD can field 7nm processors early this year, it will mark the first time in the company's history that it has had a process node leadership position over Intel. That should equate to faster, denser, and less power-hungry processors than Intel's 14nm chips."

 

I guess I should have bought AMD when it was down around $17 per share only a a couple weeks back.

Sounds good, but how long do mortals have to wait for the consumer versions?
