There was always one reason: limited memory bandwidth. You simply couldn't cram enough pins and traces for all the processor io plus a memory bus wide enough to feed a powerful GPU. (at least not in a reasonable price)
- hajile 5y agoWe solved that almost a decade ago now with HBM. Sure, the latencies aren't amazing, but the power consumption numbers are and large caches can hide the higher access latencies pretty well in almost all cases.
- terafo 5y agoOnly time that I can remember HBM being used with some kind of integrated graphics was strange Intel NUC with Vega GPU and IIRC correctly they were on the same die.
- jagger27 5y agoThat product had an Intel CPU and AMD GPU connected via PCIe on the same package, not the same die. It was a neat experiment, but it was really just a packaging trick.
