  • Valtonen says that this has made the CPU the weakest link in computing in recent years.

    This is contrary to everything I know as a programmer currently. CPU is fast and excess cores still go underutilized because efficient paralell programming is a capital H Hard problem.

    The weakest link in computing is RAM, which is why CPUs have 3 layers of caches, to try and optimize the most use out of the bottleneck memory BUS. Whole software architectures are modeled around optimizing cache efficiency.

    I’m not sure I understand how just adding a more cores as a coprocesssor (not even a floating-point optimized unit which GPUs already are) will boost performance so much. Unless the thing can magically schedule single-threaded apps as parallel.

    Even then, it feels like market momentum is already behind TPUs and “ai-enhancement” boards as the next required daughter boards after GPUs.
