I thought we were talking about Xeon D (1700 series specifically called out)—the typical CPUs in that range are in the low 100s of Gflops, similar to the performance of this 4 node cluster of RK3588s.
Obviously, throw a 64, 96, or 128+ core EPYC or the latest Xeons at it and that will make it cry (while gobbling up hundreds of watts doing so ;)
Only the Xeon D-2700 series starts touching above 500 Gflops in that generation, and those CPUs (just the CPUs, mind you) are in the $1000-2000 range, over 100W TDP.
- dragontamer 3y agoXeon D 2700 comes in 16-core flavors. At 2GHz AVX512 with 1x FMA per clock tick, that's at least 1TFlop, especially because other pipelines are still available to contribute to the processing. 2GHz x 16 SIMD (32-bits per lane) x 16 cores x 2 ops per instruction (Multiply+Accumulate) == 1TFlop or there-abouts. > Obviously, throw a 64, 96, or 128+ core EPYC or the latest Xeons at it and that will make it cry (while gobbling up hundreds of watts doing so ;) And those are closer to 4 to 10 TFlops. The bigger Xeons are 2x FMA or more instructions per clock tick IIRC. So not only are there more cores, each core can do double the work. We are talking about the "little" Xeon D with relatively low clocks. But 512-bit FMA really gets going. --------- GPUs are well into 20TFlop to 50TFlop regions. ------- Although I'm calculating ~32-bit Flops, you may have done 64-bit Flops. Its a bit ambiguous but we might not be apples-to-apples yet.
