AMD new Instinct MI300A is the most powerful APU ever with 24 Zen 4 cores and an ultra-powerful GPU that matches Nvidia’s best — it is shipping today and could be the biggest threat yet to Nvidia H100’s hegemony

AMD has unveiled its latest accelerated processing unit (APU) built on the Zen 4 architecture in the form of the MI300A – which is expected to give Nvidia a run for its money as organizations flock to buy up components to power AI workloads.

The unit – the first APU for data centers, AI, and high-performance computing (HPC) workloads – comprises 24 threaded CPU cores alongside 228 CDNA 3 compute units that make up the GPU element.
