As mentioned, the ALU architecture as well as ISA of the new A-Series is fundamentally different to past Imagination GPUs, and in fact is very different from any other publicly disclosed design.

uma das partes mais interessantes é esta

One such existing feature is the integration of a small dedicated CPU (which we understand to be RISC-V based) acting as a firmware processor, handling GPU management tasks that in other architectures might be still be handled by drivers on the host system CPU. The firmware processor approach is said to achieve more performant and efficient handling of various housekeeping tasks such as debugging, data logging, GPIO handling and even DVFS algorithms. In contrast as an example, DVFS for Arm Mali GPUs for example is still handled by the kernel GPU driver on the host CPUs.

Isto é naturalmente para um segmento que não vai fazer mossa no mercado PC, não é esse o mercado, mas não deixa de ser interessante ver mais um "back from the dead".

Agora só falta a S3 para completar a trilogia...
