Sounds like gpu to me.
- pavlov 2y agoThe Xeon Phi was a “manycore” x86 design with lots of tiny CPU cores, something like the original Pentium, but with the addition of 512-bit SIMD and hyperthreading: https://en.m.wikipedia.org/wiki/Xeon_Phi https://en.m.wikipedia.org/wiki/Xeon_Phi
- rbanffy 2y agoIIRC the first Phi has SMT4 in a round robin fashion similar to the Cell PPUs. To make a core run at full speed, you should schedule 4 threads on it.
- p_l 2y agoThe very, very first Phi still had its ROPs and texture units, being essentially a failed GPU with identifying marks filed off (yes, the first units were Larrabee prototypes with video outputs unpopulated)
- rbanffy 2y ago> the first units were Larrabee prototypes with video outputs unpopulated Such a shame. I'd love to base a workstation on those. Seems to be a hobby I never quite act upon - to misuse silicon and make it work as a workstation.
- ColonelPhantom 2y agoGPUs are actually SMT'd to the extreme. For example, Intel's Xe-HPG has 8-wide SMT. Other vendors have even bigger SMT: RDNA2 can have up to 16 threads in flight per core.
