Discussion RDNA 5 / UDNA (CDNA Next) speculation

Not sure, if this was mentioned earlier

Here comes Helios​

Slated to be available in 2026, AMD’s Helios rack infrastructure is a unified architecture designed for both frontier model training and large-scale inference, delivering “leadership” across compute density, memory bandwidth, and scale-out interconnect.

The double-wide Helios AI rack is fully integrated with AMD’s Zen 6 Eypc CPUs, MI400 GPUs, and Vulcano NICs.

should be pretty easy for AMD to squeeze out 3x with RDNA5

MLID is claiming this for raster tho, not RT/PT.

This is what makes me think it's pretty bad info.

Due to Infinity Cache and higher clocks on the desktop RDNA2 cards, the PS5 and Series X perform close to the 6700 non-XT.

The consoles of that generation also have fancy game asset compression compunded by direct SSD access by default which can't be understated as an advantage.

Yes, and 5 years later we still don't have any decent PC replica, let alone upgrade, of the PS5's I/O engine. With PCIe 5.0 SSDs doing 14GB/s reads we can now brute-force a similar throughput to the VRAM, but Direct Storage is kind of a virtual stillborn at the moment, so we're at that weird moment where the $400 5 year-old PS5 gets shorter loading times in most games than a month-old $4000 PC.


However I wouldn't say that counts for GPU performance unless we're talking about VRAM limits and traversal stutter.

PS5's I/O engine.

The key part in it is hardware decompression (dedicated, not on GPU), which is present in Xbox too also but for some odd reason no support in DirectX PC - GPU decompression is crap idea, perhaps next "Xbox" will finally have it added, without that Direct Storage is not solving much
