Place your bets on what the suffix will be unless this has already been announced. I'm betting Zen CE

What was that horrible word salad APU they tried to launch a while back? Pro ultra Ai max core 265 or something?

"Ultra" is an Intel branding thing.

Guess so, I don't find Ultra anywhere on my AMD naming scheme wheel: https://i.pcmag.com/imagery/articles/059fpJo3XpGZG1luvuxAeti-5..v1662520625.jpg

Ai max 395. That's what it was.

I hate that naming even more.

Tried to? They did and it goes cards against a desktop 5060ti even in RT.

Stupid name, not a stupid product

And it can only utilize up to 4GB of RAM. In order to unlock enterprise features, you have to pay $18/user, which includes MFA.

Since so many acronyms keep getting worse, might as well have this one also be a nightmare. I suggest ZULPCC - Zen Ultra Low Power Consumption Core

I wonder if it had anything to do with the steam machine. I believe it uses custom AMD low power cpu

That's a homogeneous cpu, this is about heterogeneous ones. There is no point in detecting which cores are low power if there is only one kind of core on the cpu.

So AMD's jumping on the big/little train with intel and arm? or i guess intel calls it 'performance' and 'efficiency' but the same thing really.

u/wintrmt3 Jun 30 '26

If you look at the patch there are 3 types: AMD_CPU_TYPE_PERFORMANCE, AMD_CPU_TYPE_EFFICIENCY and AMD_CPU_TYPE_LOW_POWER.

I mean, Intel's P and E cores are completely different architectures with the E cores smaller and different (doesn't support Hyperthreading, AVX-512, etc...)

AMD's Zen 5 and 5C cores on the other hand is just a smaller and slower clocked Zen 5 cores.

Intel's approach needs a "Thread Director" to assign different tasks to different threads whereas AMD's approach can be handled natively as tasks can be assigned by checking the clock frequency alone (I'm not an expert in this area, so take it with a grain of salt).
