To the first question: blame Windows I guess. But even on older chips, GPU code could access memory allocated on the CPU side so this didn't cap the amount of data your GPGPU code could crunch.
- littlecranky67 6mo agoI remember this was mostly a BIOS setting how much memory to allocate for iGPU - and once set in the BIOS, that memory was not accessible to the underlying OS (besides GPU I/O).
- fulafel 6mo agoYes, but this was to appease Windows, probably older versions and/or 32 bit versions of it.
