>It's not new, AMD has been doing this for a while with their Infinity Fabric technology (and before that, technologies like SLI and Crossfire achieved the same thing on a software level) None of those technologies make multiple GPU dies look like a single physical GPU to software. As covered by the Anandtech quote you dislike so much: > This has made combining multiple GPUs in a transparent fashion something of a holy grail of multi-GPU design. It’s a problem that multiple companies have been working on for over a decade, and it would seem that Apple is charting new ground by being the first company to pull it off. However, that article does go into additional detail. >Unlike multi-die/multi-chip CPU configurations, which have been commonplace in workstations for decades, multi-die GPU configurations are a far different beast. The amount of internal bandwidth GPUs consume, which for high-end parts is well over 1TB/second, has always made linking them up technologically prohibitive. As a result, in a traditional multi-GPU system (such as the Mac Pro), each GPU is presented as a separate device to the system, and it’s up to software vendors to find innovative ways to use them together. In practice, this has meant having multiple GPUs work on different tasks, as the lack of bandwidth meant they can’t effectively work together on a single graphics task. https://www.anandtech.com/show/17306/apple-announces-m1-ultra-combining-two-m1-maxes-for-even-more-performance https://www.anandtech.com/show/17306/apple-announces-m1-ultr...
