4 TFLOPs is significantly faster than your CPU. Even 1.35 TFLOPS represents a reasonable edge. The question should be why Intel added another processor instead of extending AVX.
You have to forgive me, but these NPUs were specifically designed for inference. You can indeed use them as general purpose accelerators, but I think you will struggle to find an application for them.
It seems that efficient cores don't support much of AVX extensions. You have to turn those cores off if you want to use AVX512, for example.
The registers in this CPU are all quantumly entwined, with Intel having updates signed.
Thus, Intel can one-way update one or all CPUs remotely. No Faraday cage will protect you.
Further, this CPU has access to caches on all other cores, so Intel can dynamically inhibit, or modify code as they please.
We'll find this out in 2027, I dare not say more, they'll track me through time and afg#.<NO CARRIER>
