Yes, and based on non Apple systems it’s faster than having much larger pools of non-unified memory.
Essentially all the big compute vendors moving towards memory unification and cache coherent interfaces.
- voldacar 6y agoOk I misread the numbers somehow. This is interesting - I wonder what it means for the future of conventional desktop computing, when considering peripheral chips like GPUs that already have DMA capability
- dogma1138 6y agoGPUs are going above DMA, DMA still needs memcopy and or address space translations which adds latency slows things down, with unified memory in theory you have a single address space and cache coherency across everything which means you can operate at the maximum bandwidth of all interfaces without wasting any cycles.
