Over the past three days the new AMD "GFX1250" GPU target has started being built out within the upstream LLVM compiler codebase for the AMDGPU LLVM shader compiler back-end.

What AMD GFX1250 will correlate to remains to be seen. Based on prior AMD GFX1250 reference leaks there was some speculation that it could be for their upcoming UDNA architecture but that more likely will be for GFX13. AMD GFX1250 if following the convention used by RDNA3.5 with GFX1150 could end up being an RDNA4 refresh / "RDNA4.5" for potential future APUs

Holy hell that was targeted towards people who know a lot more than I do... Could anyone explain in layman's terms what all this means?

AMD Mobile chips tend to use a "half-generation" refresh of their main GPU architecture. For example the rdna3 Desktop line is gfx1100, gfx1101, gfx1102 depending on the model. The new mobile GPUs in the strix point CPUs (I. E. the new framework models) have gfx1150/gfx1151 denoting their rdna3.5 refresh.

The UDNA is in reference to amd stopping to have two lines of internal architectures: RDNA for graphics (Radeon cards) and CDNA for compute (like the MI line of chips) and instead have one architecture for both, labeld UDNA.

Ah man, thanks so much. And by "refresh," you mean just releasing new hardware models?

Minor Hardware changes, essentially bugfix and small feature updates in Hardware. Often with a better manufacturing process improving yield and power consumption.

Probably a console or laptop chip
