What i'm interested on is "256b GDDR7" What does that mean? They couldn't possibly be including 256bits of GDDR7 memory inside the chip, is that 256bits in like the memory interface? Is that a confirmation of at least 4GB of GGDR memory integrated inside the APU like Apple M SOCs? That would remove the current limitation of iGPUs that being memory speed and latency since they share system memory.
