In my current desktop PC, it’s 700 GFlops theoretical compute versus 50GB/sec of theoretical RAM bandwidth.
- m0zg 7y agoFor i9-7980XE Intel quotes 1.3TFLops of fp64. So it ought to do about twice that at fp32. Yours at $1500+tax from Newegg: https://www.newegg.com/core-i9-x-series-extreme-edition-intel-core-i9-7980xe/p/N82E16819117836 https://www.newegg.com/core-i9-x-series-extreme-edition-inte.... Quad channel RAM, too. For a flea check, consider that the chip has 18 cores and runs at ~4.2GHz. To achieve the theoretical throughput each core has to do ~30 single precision flops per cycle. Which sounds about right: HEDT intel chips can (theoretically) do 32 of those per cycle. This, of course, ignores whatever throttling Intel would need to apply to maintain TDP, so a purely theoretical back of the envelope.
