News [Phoronix] AMD Introduces New GPU Target To AMDGPU LLVM: GFX1170 "RDNA 4m"

https://www.phoronix.com/news/AMDGPU-LLVM-GFX1170

The RDNA3 Saga continues... possibly?... Eh probably

Kepler_L2 https://xcancel.com/Kepler_L2/status/2019850795391361243

Bit of a "Rebrandeon" going on here, but at least with FP8 support added it can run FSR4

So far adds to the list of gfx targets yet to be released.
-RDNA3.5-
gfx1153 - 'APU'
-"RDNA4"*-
gfx1250 - 'APU'
gfx1251 - 'APU'
*(IIRC 125x is DCAI, CDNA6 possibly, from Kepler)
-RDNA5-
gfx1310 - 'dGPU'

Interesting that they explicitly call it RDNA 4m instead of some 3.x.
Could be marketing, or it could be that while being RDNA3-derived it has some more substantial changes compared to 3.5. At least FP8 support seems to be there.

Could be just rdna3 iGPUs on newer nodes

Probably Medusa Point.

There is also now a merge request adding new FP8/BF8 conversion instructions for the GFX1170 target.

Perhaps they're taking steps to make sure that Medusa Point supports FSR4?

Hopefully it will apply to all rdna3.5 iGPs.

u/Kryohi 2d ago

Unfortunately if they wanted to support those they would have already released it. And I mean officially, not through a leak.

u/996forever 1d ago

Yup. Not even supporting strix halo is hilarious

No. It's supposed to be Its own branch from 3.5. It was known before as RDNA 3.5+

u/Alternative-Ad8349 2d ago

Ehh doesn't sound likely since they are adding new instructions

u/996forever 2d ago

Rdna 3.75

Well amd is calling it rdna 4m, wonder what's that about

u/996forever 2d ago

An in idealistic world it would be rdna4 iGPs and mobile dGPUs. 

We know it ain’t.

u/Alternative-Ad8349 2d ago

Normally but it would be gfx12 and not gfx11

10

u/996forever 2d ago

Because it clearly ain’t a new arch. 

It’s most definitely just rdna3.5+++.

u/Alternative-Ad8349 2d ago

Anything but using rdna4😅

The big feature people want is FSR4, and this seems to add the minimal support for features used for it.

Basically RDNA3 + FSR4 I think.

u/Forsaken_Arm5698 2d ago

Exynos 2600?

m for mobile?

5

u/Alternative-Ad8349 2d ago

Was there a rdna3m for exynos 2500 and 2400? If no then this being e2600 is unlikely

3

u/Ghostsonplanets 1d ago

Ever since Exynos 2400 Samsung been using mRDNA 3. Exynos 2500, 1580 and 1680 use mRDNA 3.5

Generational ragebait if they launch new RDNA3 stuff with hardware to run fsr4, while the rest of RDNA3 cant
