Intel i7-8700K vs AMD TR 2990WX energy efficiency comparison

Processing time and energy efficiency is compared with two PCs, Intel i7-8700K and AMD TR 2990WX.

The processing task compared is WWAudioFilter 1.0.54 jitter-add with FIR window size=65537 to 44100Hz mono PCM signal of 1800 second. It is double-precision 1D convolution.

Result

• AMD TR 2990WX is 3 times faster than Intel i7-8700K.
• Energy efficiency is increased when TDP is reduced (CPU is downclocked).
• AMD TR 2990WX TDP 250W is roughly the same energy efficiency as Intel i7-8700K TDP 65W.
