8 cores with 528 thread? What’s the math? I assumed 512 but had to reread it
Here is an interesting one. Intel has a 66-thread-per-core processor with 8 cores in a socket (528 threads?) The cache apparently is not well used due to the workload. This is a RISC ISA not x86.
where 2 is number of slow threads, like current CPU,
and 64 are more like GPU threads.
This architecture could be next step in GPU integration. Hope they manage to write efficient implementation for standard math libs. It could be faster than separate CPU+GPU in one package.
The diagram shows 8 gray boxes (in 2 columns of 4). Each gray box is a core.
Above that is a detailed view of what each core looks like. There's a middle section labeled "Crossbar", and above that are 3 boxes labeled STP, MTP, and MTP. Below that are another 3 identical boxes. So each core has 4x MTPs and 2x STP.
What are those? The text of the same slide says MTP is "Multi-Threaded Pipelines" with "16 threads per pipeline" and STP is "Single-Threaded Pipelines" with (self-evidently) 1 thread per pipeline.
And 4 * 16 + 2 * 1 = 66, so 66 threads per core.
