They need to prove they can do a few things before I'm worried. * They need to ramp the clockspeeds -- much easier to say than do. * They need to include 256 or 512-bit SIMD operations without breaking the power budget. * They need to design a consistent and fast RAM controller (and likely need to add extra channels) * They need to integrate power-hungry USB4/thunderbolt into their system. * They need to add a dozen extra PCIe 3 or 4 lanes without ballooning the power consumption. * They need an interconnect (like QuickPath or HyperTransport/Infinity Fabric) so all these things can communicate. These are the hard issues that Intel, AMD, IBM, etc all must deal with and form a much bigger piece of the puzzle than the CPU cores themselves when dealing with high-performance systems.
