AMD RDNA 3 ‘GFX11’ GPUs May Feature Hardware-Accelerated FSR 3.0 Tech Thanks To WMMA ‘Wave Matrix-Multiply-Accumulate’ Instructions

This Q4 is looking soooo good.

Sounds like they added tensor cores. Would it be only for upscaling or other features? I wonder if it means FSR 2.0 can only go so far... maybe its an 8k thing.

[Trunks0]

It's more likely they are extending the feature set of the CU's further. As the article mentions, CDNA already is capable of this.

Def a good thing to move to a wider 384 bit bus.

The calm before the storm. It has been relatively quiet in terms of leaks for RDNA3 architecture. However, it appears that AMD themselves made a surprising commit to AMDGPU Linux drivers, which has been immediately spotted by Kepler and other leakers.

The patch lists MCD_INSTANCE_NUM which is a number of supposed Memory Complex/Controller Dies for RDNA3 Navi 31 architecture. Interestingly, just a week later AMD replaced MCD with UMC_NODE, seemingly to hide the leak.

If this is true, then this would confirm previous rumors that Navi 31 has a single GCD (Graphics Complex Die) and six MCDs. Ultimately this means that the card has a 384-bit memory bus and most likely a total of 192 MB of Infinity Cache or 384MB if AMD were to use V-Cache on top of each MCD as suggested by Kepler.

FINALLY

[acroig]

[bill dennison]

so 12288 SP's ?

[pax]

My bet is its a cut down die where the full die is the ~ 15000 one

makes me want to wait on the 7950 xt

at least to see it and it's review and price


as it looks like this was right

16384 shaders? dang... They have dropped prices lately but its finally looking like clearance prices... I think the 7950 will be 1500$.

7900 1200$

Way it sounds lately tho theres only one compute die. Some recent leakers seem to be going that route. 1 Compute die and 6 MCD. Not sure they could fit 2 of those short of doing a dual gpu board a la R295x2.

i think the 7950 xt is or maybe 2 compute dies of 2x 7800 xt compute die the numbers match

there was some leaks that only the 7950 would be 2 compute dies q1 next year

We don’t know whether the supposed Radeon RX 7950 XT will be a chiplet-based design or monolithic like Navi 31 (ignoring the MCDs), but RedGamingTech claims the former. According to them, it’ll feature two Graphics Compute Dies (GCDs) with 64 CUs and 8,192 shaders, each. It’s unclear whether the Infinity Cache will be scaled as well but 512MB is being speculated by some.

AMD’s Radeon RX 7950 XT May Feature Up to 10 Chiplets: 8 MCDs, 512MB Infinity Cache, 512-Bit Bus, & 16,384 Cores [Rumor]

AMD Navi 33 “RDNA 3” GPU is said to be installed in the middle range Radeon RX 7600 XT graphics card around $ 400, which is faster than RX 6900 XT

where there is fud there is hope

[acroig]

We live for FUD that gives us hope.

Will it be able to run RT?

like a bat out of hell

Like Nvidia or like last time…

[Trunks0]

Like Nvidia or like last time…

Well right now it runs better than Turing, but worse than Ampere. But without a real DLSS 2 competitor they where stuck till FSR 2. This next time around I'm expecting RT performance on par or better and I expect FSR 2 to be pushed hard AF going forward along with an updated FSR 2 Plus, or whatever, that can do more because god damn it I want a battle to RAGE!!!!

I seriously doubt it but we will see. Do the games that have Nvidia RTX badging now work on AMD cards or are they still Nvidia locked?

I think the only game left that's is nVidia only for RT is Wolfenstein Youngblood. Everything else updated to standard RT API extensions.

But RTX branding now apparently means RT+Ai... RTX branding is a mess...

Even Quake 2 RT? Nice.

Even Quake 2 RT? Nice.

Gai ppl have been able to run Quake 2 RTX on AMD since December 2020 :D

They even added support for FSR 1.0 alas no support for FSR 2.0 but here's hoping someone submits a pull request one day that slides it in ^_^

Noice! Had not heard, TY.

Currently playing Quake 2 RTX with AMD FSR 1.0 enabled.

It feels good using something from AMD again.

AMD's Next-Gen Flagship RDNA 3 GPU Die Might Be Much Smaller Than You Think

According to Greymon55, the GCD, the actual "processing" part of the GPU, will only be 350 mm² This is controversial primarily because seems like an improbably small processor for the predicted specifications of Navi 31. The top-end RDNA 3 part is expected to have 2.4x the shader cores of Navi 21, and even if we account for the shift to TSMC 5N, as well as the removal of the memory interfaces and Infinity Cache from Navi 21, we would still be looking at some 375 mm², according to German site 3DCenter.

Kepler and Greymon55 are actually in agreement on the die area. Kepler's original statement about "total die area" seems to have been including the six MCDs that we expect the final product to have. He himself commented on the surprise at the die area prediction, noting that the RDNA 3 architecture actually discards "a lot of old architectural bloat."

https://hothardware.com/news/flagshi...might-be-small

[pax]

Yea they took out a lot of old hw that was more meant for pro cards. Itll still pack the 15-16k shaders and RT units. Looks like the rdna for gaming and cdna for pro segmenting is just about done.

[acroig]

https://wccftech.com/could-amds-rdna...f-over-6-tb-s/

[pax]

So they think the each 'extra' 128 megs will be on its own chip and data paths the one 128 IF cache in the 6900xt... Not sure that will be true on 5 or 6nm node. It could be just one big cache on the Compute die or have smaller data paths on the separate MC dies... not being on die will probably cause some BW/latency hit.

Oh I meant Intel in the CPU front only as their ARC cards are DOA.

they are banded in my book till 2037

they treated us like dogsh*t for the 20 or so years of bad AMD CPU's and we had to buy Intel
high prices
and they still need a new MB with every new CPU


so they got a 20 year moratorium after 2017 Ryzen release
I may not ever buy Intel again


and the Ryzen 9 7800X3D, 7950X3D are looking good if they make both this time

[demo]

Expected/leaked pricing and performance vs 3090 at 6 min. Impressive.

Following Nvidia RTX 4000, AMD allegedly bumping up power draw for RX 7000 (RDNA 3) too

The report comes via YouTuber RedGamingTech (RGT) who says that the Radeon team is increasing the total graphics power (TGP) of the top end Navi 31 chip from 375W to 405W, which is bump of 8%. Meanwhile, apparently there will also be another more efficient SKU based on this that will feature the 375W TGP.
