They were waving their hands around a bit saying that in addition to on-package RAM with high bandwidth, they have done optimizations inside driver, OS and APIs to eliminate 1 or even 2 or more RAM to RAM copies for common tasks. So maybe there is a higher effective bandwidth when comparing to Wintel machines. It was very vague. Would love to read a detailed article comparing the systems.
- wmf 6y agoIntel and AMD theoretically also support zero-copy but I wonder if it gets used in reality since most apps are probably optimized for discrete GPUs.
