Speculation: Ryzen 4000 series/Zen 3

[lobz]

What about 35W and 45W?
Because the uncore eats up too much power leaving almost nothing to the cpu cores. Even 8 core Epycs uses lot's of power.

I wonder why amd never released some Epyc 5000 series (TR platform based) and Epyc 3000/Opteron 3000 series (am4 platform based). It seams they have a large gap (read market) to fill in servers.

In Renoir the power saved on the I/O die and IF links goes to graphics, so that's always gonna be a stretch either way. Couple of weeks and we'll see Here's hoping Vega won't be too much of a drag.

at 95W it does 4.0GHz
at 65W it does 3.55GHz
at 45W it does 3.05GHz
at 35W it does 2.5GHz
at 25W it does 1.25GHz

45W numbers are interesting if the Renoir rumors of 45W 'H' models are true.

Wow, for more 10W it doubled the clock.

That did seem like an outlier so I tried it again. This time upon restart I let it idle for a bit longer than normal to make sure nothing in the startup process would effect it. It did a bit better. It bounced around a lot between 1.3-1.5GHz. I'd say it averaged around 1.375-1.4GHz during the run. Still a 1.1GHz boost for 10W is crazy. My guess is at that low wattage so much is spent on the IF and memory controller and other necessities that the cores themselves don't have much power to use.

Would be nice to see AMD make more gains in this area.

All the leaked results I've seen so far have been from AMD test systems, or alternatively from ASUS and HP. So add those last two companies onto the list of Renoir adopters.

GPU downgrade speculation. 8CU seems likely, and this would max out budget dual channel ram. Some hardcore driver RE by lobz' guy:

I'm sorry... what?

I believe _rogame reverse engineered the drivers to some extent and he thinks the CU count is 8 rather than the previous rumors of 12 or 13; I may be wrong though. I just skimmed the info.

Oops (edit), okay going back this thread (post #1551) it seems rogame is uzzi's "guy" not yours; sorry for my confusion.

Man, when the big time wall street guy aka liahos mistook me for @uzzi38 , I thought damn if it's that easy to steal someone's identity.

Yep, you're correct. That's almost exactly what he did. What he found was pretty clear.

Arcturus is 8 Shader Engines with 16CUs each (128CUs total)
Navi12 is 2 Shader Engines with 10WGPs each (40CUs total)
Renoir is 1 Shader Engine with 8CUs in it.

 

[Kenmitch]

Wow, 45W? Ryzen Master is/was supposed to have an eco mode that limits the TDP to the next range down. A 95W becomes a 65W, a 65W becomes a 35W, etc. I don't see it on my 2600X. I can limit wattage in the BIOS though.

You need 3xxx series to use ECO mode.

 

[IntelUser2000]

It probably means a variant of Renoir has 8CUs, rather than that really being the maximum. That's why other numbers float around.

That's what I was thinking. Ryzen Master seems to have a different GUI for Zen 2 as well. Not that it matters, I can adjust wattage at will should I ever want to.

This is the wrong thread for Renior (Zen2j speculation. Duh.

 

[NostaSeronx]

This is the wrong thread for Renior. Duh.

Renoir is a 4000-series processor, dum dum.

For all we know Renoir might even have a bit of Zen3 SMU or whatever.

 

[DrMrLordX]

Not necessarily. Are there going to be any 4xxx-numbered Renoir products?

Lends credence to the Apple only Navi10 HBM variant rumour?

Unless Navi10 also had significant errata now fixed, or pieces missing now added to Navi12 that makes it viable giving it a new name beyond HBM2 support alone.

No, he looked at firmware. What he found is in regards to the full die.

However, we both believe it may not be accurate as again, rumour suggests otherwise. And we asked several people up the rumour foodchain as well, who also said it didn't line up with what they'd heard. Feel free to disregard it.

HBM2 is basically confirmed. Navi 12 is almost certainly mobile focused too.

But Navi 10 also did have errata that is being adressed with Navi 12.

(SDMA stands for System Direct Memory Access).

I wonder if this will lead to extra efficiency or performance beyond HBM2.

Well, I can't say I know what SDMA is actually for, but if I'm gonna take a guess from the name, whatever this errata is, I get the feeling it's directly related to the PCIe Gen 3 vs PCIe Gen 4 weirdness surrounding the 5500XT.

PCIe Gen 3 vs PCIe Gen 4 weirdness surrounding the 5500XT.

I thought you could only run Navi cards on Gen 4 anyways?

 

[uzzi38]

Nah, you can switch between the different modes in BIOS afaik. I think so anyway, I don't actually have one myself.

There is no weirdness.

What happens is that in ALL PCIe 3.0 boards, the 5500XT works @ x8 PCIe 3.0 while with X570 boards it works @ x8 PCIe 4.0. The difference stems from the fact that boards with PCIe 3.0 have HALF the bandwidth of X570 boards, that have PCIe 4.0.

Effectively, when you place ANY PCIe 4.0 card in a non-PCIE 4.0 board, you're bottlenecking the card's true performance. It the case of the 5700(XT) card(s) you don't notice it much because of the VRAM present in the card but you may notice in SOME games if you use a 5500(XT) card.
