Alleged AMD Instinct MI300 Exascale APU Features Zen4 CPU and CDNA3 GPU

[AleksandarK]

Today we got information that AMD's upcoming Instinct MI300 will be allegedly available as an Accelerated Processing Unit (APU). AMD APUs are processors that combine CPU and GPU into a single package. AdoredTV managed to get ahold of a slide that indicates that AMD Instinct MI300 accelerator will also come as an APU option that combines Zen4 CPU cores and CDNA3 GPU accelerator in a single, large package. With technologies like 3D stacking, MCM design, and HBM memory, these Instinct APUs are positioned to be a high-density compute the product. At least six HBM dies are going to be placed in a package, with the APU itself being a socketed design.

The leaked slide from AdoredTV indicates that the first tapeout is complete by the end of the month (presumably this month), with the first silicon hitting AMD's labs in Q3 of 2022. If the silicon turns out functional, we could see these APUs available sometime in the first half of 2023. Below, you can see an illustration of the AMD Instinct MI300 GPU. The APU version will potentially be of the same size with Zen4 and CDNA3 cores spread around the package. As Instinct MI300 accelerator is supposed to use eight compute tiles, we could see different combinations of CPU/GPU tiles offered. As we await the launch of the next-generation accelerators, we are yet to see what SKUs AMD will bring.

One word: monster !

But can it pull 900w???

I think ROCm added support for unified memory a while back, this could be huge, one of the really annoying things in GPGPU is CPU to GPU communication and being limited by VRAM size. Now that the CPU and GPU are physically so close and can share faster DDR5 memory it could solve a lot of headaches.

Computer on a card, blade server?

Boltzmann Initiative gave support for unified memory (HSA / Heterogeneous System Architecture). A few years later, Boltzmann Initiative was renamed "ROCm".

So ROCm arguably had support for unified / HSA adjacent memory since before it was even named ROCm.

Now slap it in a 55W package and you win the laptop market!

Why stop there? Slap it into a 2W package and you win the smartphone market.

Lol. I was waiting for a sub 1W smartwatch response.

50mw, rule the space station sensor market!

Expect a call from AMD soon! They need talanted guys!

It should be able to generate 50 mW just by harvesting cosmic rays, even on the ground. The chips are large enough for that.

Yeah, a $2000-3000 starting price laptop.

Remember that the Instinct MI accelerators are not GPUs, they don't have display output, and they're not designed for gaming at all. So any laptop with this APU must also have a GPU of some sort.

Yes, you are correct. The hint here is the smiley face at the end of my post.

 

[Assimilator]

I thought "APU" was what AMD calls their CPUs with built-in iGPU...

U$ 7000-10k*** fixed for you.
