Solid gains of 15-18% IPC, but we’ll see what actually gets implemented. I haven’t followed recently so I don’t know if it’s still a problem but implementation would sometimes suffer compared to “paper performance” - e.g. historically ARM would design cores with a range of possible cache sizes but Qualcomm et al would always go on the smaller side of cache, hurting performance on high end cores.

Will be interesting to see how they compare to Apple’s current generation offerings as well as its next generation of A/M processors.

Since they are going with TSMC N3E we probably won’t see anything with these new designs until early-mid 2024.

Interesting - not allowed to implement the low performance version on its own. Also once again a range of cache sizes are possible for any given design so we’ll see what implementations are actually actualized.

… Arm also specifies that the Immortalis (10+ core GPU) must include a hardware ray-tracing unit. The major feature update in this generation is Deferred Vertex Shading (DVS). This appears to involve postponing most of the heavy rendering work until after the geometry processing is done, at which point any hidden surfaces can be discarded rather than being rendered. … Arm said that this was implemented to cope with the growing scene complexity of games … it requires 40 percent less memory bandwidth … the new GPU claimed to be 15 percent more energy efficient on average​

So it’s similar to Apple/Imagination’s design now? @leman this might interest you. Also of course it will be interesting to see how their ray tracing stacks up

Sounds like TBDR, but hard to say without knowing more. The terminology has been used rather liberally

2024 ARM announcements:

Arm takes aim at client PCs with new 3nm compute subsystems, offering pieces of its IP to its customers for desktops, laptops, and tablets

Arm's new compute subsystems can enable PCs and tablets running Android, Linux, and Windows.

Unclear how the new P-core compares to Qualcomm/Apple. The article from Gavin reads … oddly. Like he just transcribed ARM marketing which was filled with a lot of fluff and little substance. Very odd. Still some of it sounds quite promising if I can get past the buzzwords and lack of detail.

He did not write it, he just delegated the composition to some LLM. Possibly one running on an ARM-based platform?
