AMD readies Phoenix3 and Phoenix4 APUs, PCI IDs leak reveals

AMD getting ready Phoenix3 and Phoenix4 APUs

It appears just like the Phoenix household is rising.

Based on the brand new entries to the general public PCI System ID repository, AMD could also be getting ready further variants of the Phoenix sequence. The Phoenix APUs are already out there on two separate dies, one referred to as Phoenix1 and the opposite referred to as Phoenix2, which can be referred to as Small Phoenix. There are some vital variations between the 2 processors, because the latter affords fewer cores and a closely decreased RDNA graphics subsystem.

AMD Phoenix(1) options 8 Zen4 cores and as much as 12 RDNA3 Compute Items, whereas Phoenix2 has 2 Zen4 cores and 4 Zen4c cores mixed with as much as 4 RDNA3 CUs. These chips are listed beneath ID of 15BF and 15C8, however one ought to be aware that this ID refers back to the graphics subsystem.

The database now lists Phoenix3 as “1900” and Phoenix4 as “1901”, that are very distant IDs from the unique “15BF” and “15C8”. Subsequently, a query have to be requested if Phoenix3/4 are primarily based on RDNA3 or one thing solely completely different like RDNA3.5. As we all know, AMD now tends to combine architectures, combining Zen and RDNA structure just isn’t precisely a difficulty for AMD today.

The present driver for the Phoenix sequence lists over 483 variants of PHX1 and 19 variants of PHX2, these are usually completely different implementations for OEMs. The overwhelming majority of them could have the identical specs, however to make sure full compatibility AMD driver detects every variant beneath a special Sub System ID. These are Radeon 780M, 760M, and 740M built-in graphics. Notably, the identical driver has no references to Phoenix3/4 but, subsequently the supply of this leak remains to be unknown.

If we had been to guess, these may might be refreshes, probably meant for the next-generation cellular lineup aka Ryzen 8000. Price including that AMD is now getting ready its “Hawk Level” sequence which is derived from present Phoenix chips. Maybe that’s the place Phoenix 3/4 is heading?
