Agree on both! New Xeons are very interesting that could be the next workstation to go for, and HP's fiasco marketing does absolutely nothing to effectively communicate the differentiating benefits, missing the opportunity to put Xeon based workstations back in the game. Need to let them go...

FP on AIDA64 on a AVX-512 capable CPU becomes almost pure AVX 512 test (at least that will drive the temps)! Loading all 10 cores' AVX-512 units 100% simultaneously for 10's of minutes and with low or now negative offsets (4.8Ghz is shown) is incredibly taxing and heat generating. This is why...

Correct! Already Skylake/Cascadelake gen of server CPUs from intel are not bottle necked by the CPU's processing capability but by the memory subsytem. Their memory system cannot keep up with the CPU and quickly becomes the bottleneck. The only way to significantly improve is to make the...

Modern CPUs are using some math tricks but not the once you are referring to. Instead of doing the full calculation the "proper" way (like the once we learn in school): 1) for certain operations (e.g. square root, divisions) the CPU could use table look up to get to a close enough answer and...

Agree! In my experience, performance does not come from getting an IPC improvements of 10%-20% executing the same stupid sequence of instructions slightly fast, shaving of a 1/5 of a clock cycle here and there or even adding 50% more cores - that's not where it is. Performance come from: 1)...

One of the things I do not see mentioned in this thread is the new flag ship instruction set features that Sapphire Rapids will introduce: AMX. I see some discussion about AVX-512 but that's not the "new thing" with Sapphire Rapids, AMX is! In short AMX is the advanced matrix extension. It...
