How to complute FLOPS of Xeon CPUs?

I found on documents that

  • 4th Gen Intel Xeon Processor can achieve 1024 operations per cycle per core on BF16 and 2048 on INT8  with AMX.
  • 3th Gen Intel Xeon can achieve 64 operations per cycle per core on FP32 and 256 on INT8 with AVX-512 VNNI.

 

How can we get the number of FLOPS? What may I take it wrong?

 

For 3rd Gen cores, each core achieves 512(bitwidth)/32(FP32)*2(2 avx unit per core)=32 !=64

For AMX, each core achieves 1024(bitwidth)/16(BF32)**2(tile square)=4096 !=1024

And why FLOPS@INT8 != 4*FLOPS@BF16?

Hi oleotiger1


Greeting for the Day!


I hope this message finds you well. I wanted to provide you with an update regarding the recent developments in computing technology, particularly concerning Floating Point Operations Per Second (FLOPS).



Please be informed that Intel no longer makes FLOPS (Floating Point Operations) per cycle information available for Intel® processors.


Kindly go through this link for reference.


Where Can I Find Information about FLOPS Per Cycle for Intel®...


Thank you for your patience and understanding.
