Discussion RDNA4 + CDNA3 Architectures Thread

[DisEnchantment]

With the GFX940 patches in full swing since first week of March, it is looking like MI300 is not far in the distant future!
Usually AMD takes around 3Qs to get the support in LLVM and amdgpu. Lately, since RDNA2 the window they push to add support for new devices is much reduced to prevent leaks.
But looking at the flurry of code in LLVM, it is a lot of commits. Maybe because US Govt is starting to prepare the SW environment for El Capitan (Maybe to avoid slow bring up situation like Frontier for example)

See here for the GFX940 specific commits

History for llvm/lib/Target/AMDGPU - llvm/llvm-project

The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. - History for llvm/lib/Target/AMDGPU - llvm/llvm-project

Or Phoronix

There is a lot more if you know whom to follow in LLVM review chains (before getting merged to github), but I am not going to link AMD employees.

I am starting to think MI300 will launch around the same time like Hopper probably only a couple of months later!
Although I believe Hopper had problems not having a host CPU capable of doing PCIe 5 in the very near future therefore it might have gotten pushed back a bit until SPR and Genoa arrives later in 2022.
If PVC slips again I believe MI300 could launch before it

This is nuts, MI100/200/300 cadence is impressive.

Question - Speculation: RDNA3 + CDNA2 Architectures Thread

Man I have been dying to make this one for a while now. First rumours for RDNA3 are here so new thread time! Just going to start off with this one for now: kopite7kimi on Twitter: "@VideoCardz Ah, I mean a simple mcm design with 10240 cores is not enough. Because the lift from RDNA2 to RDNA3...

Maybe AMD wants their 'Radeon AI MAX 9070' to rival 'RTX 5070TI' then, 'my number is similar but bigger than yours' shenanigans.

 

[branch_suggestion]

I wouldn't touch RDNA4 if your on RDNA3 or Ada.

Well duh, 3070Ti and below users should be the targets to convert.

its not a religion lol

StrixHalo has 'Radeon 8060S' IGP and already being a sign of weird naming scheme and number

https://twitter.com/x/status/1868704882502389792

N48 might be named as just Radeon 9070 with some other suffix like S.

S suffix is for "Slim" laptops. It's not meant for desktop GPUs.

I just hope that by the time Zen6 and UDNA are out there is a cohesive branding scheme across the whole portfolio.

As long as AMD releases botched lineups - the naming scheme will suffer. They just couldn't rebrand the 7900XTX as a 7800XT because they probably wanted to charge more money, and because someone in the management chain just didn't have the balls. It goes all the way back to Polaris, where the kept on using the x80 naming for Polaris, and then had to give all kinds of special names like Fury and Vega to cards.

Note that Nvidia have been somewhat consistent with regards to naming and they do have a general framework, but they're also in flux. They had that 16 gen without RTX as a companion to the 20 gen, they've added confusing (IMO) super refreshes (4070, 4070 super, 4070TI and 4070TI super), removed the Titan card class (and it looks like the 80TI as well which was a staple) and created the 90s cards instead. They've relegated the 60s cards from midrange to entry level. The 70s card which used to be "A bit worse than the 80s card but much cheaper" have also lost much of their appeal. I wouldn't exactly compare a 1070 to a 4070 or a 1060 to a 4060, relative to the rest of their relative stacks. They also had that mess with "unlaunching" the 4080 12GB. What I'm saying is - Nvidia is also trying stuff, and changing things around.

Consumers need branding that sets an impression for what is to come and is memorable.

AMD is not competitive, branding can do only so much. They could have at least been more competitive on price/perf but they're not really.

The 5700XT was fine and obliterated the 2060, and was competitive with the 2070. RDNA2 was fine was well, although AMD overreached a bit with the 900s cards. RDNA3 was a disaster, and we'll see what happens with RDNA4... However, given it's another botched lineup - I don't have my hopes up. Rumors of using a 9070 instead of 8800 naming shows that someone might have woken up, but going totally inline with Nvidia is a terrible decision. I've said previously that 8700XT is probably the right call.

We back in 7870xt era boys.

Ye i know...
Hope my info on the 599$ is not correct coz 70series card for 599$ looks bad if you are not nvidia 4070FE looking at you xD

Maybe he give current info, then if something change he delete tweet.
9070? interesting, not R300

 

[vanplayer]

Do they really need 3 fans for supposedly lower power card, it's not supposed to be like 600W monster.

It would be much closer to 300W than 200W according to latest leak.

 

[SolidQ]

if that real, than i don't see how RDNA4 gonna take some market share. Especially 9700 with 12gb high price
Like 7800XT minus 4gb and 50$? Gonna be worst card
Interesting N44 prices 180$ is 8gb, 350 is 16GB?

 

[gaav87]

7900gre<9070xt<7900xt

if that real, than i don't see how RDNA4 gonna take some market share. Especially 9700 with 12gb high price

This looks even worse then my slower than 4070ti super 599$ info.

 

[SolidQ]

looking at this maybe 110% will be 9070XT, interesting AIB gonna hit 7900XT lvl?

 

[jpiniero]

Like 7800XT minus 4gb and 50$? Gonna be worst card

But faster than the 5060 Ti and 4 GB more ram.

 

[SolidQ]

But faster than the 5060 Ti and 4 GB more ram.

and 5060ti will outsell 9070, like 4060ti vs 7700xt

 

[jpiniero]

TBH I am more interested in seeing if they can manage to get deals at least similar to RDNA 2 in mobile.

 

[SteinFG]

If 9070 XT is not beating 7900 XT that's gonna be really bad. Double so if they raise prices above $500 with this kind of performance.

 

[gaav87]

Well:
1. Name sucks
2. Price/perf sucks
3. Middle finger to all 6800xt-6950xt owners

The 6800 is also now $400

It had hit a low of $340

f 9070 XT is not beating 7900 XT that's gonna be really bad

ver1 driver not final or some surprise for us
ver2 charge for FSR4 and RT

This is all kinds of wrong (prices are set in stone last minute for GPUs. Don't ever poast them), but they're not taking any MSS without the shotgun.

 

[jpiniero]

but they're not taking any MSS without the shotgun.

That'd kill the margins tho.

It's not like the Fire Sales helped that much.

Prices can change, agressive mss tactics would be 449-499$
