This is equal to the combined single precision GPU and CPU horsepower of a modern MacBook [1]. Really makes you think about how resource-intensive even the simplest of modern software is...

- fweimer 10mo agoNote that those 13.1 TFLOPs are FP64, which isn't supported natively on the MacBook GPU. On the other hand, local/per-node memory bandwidth is significantly higher on the MacBook. (Apparently, SGI Altix only had 8.5 to 12.8 GB/s.) Total memory bandwidth on larger Altix systems was of course much higher due to the ridiculous node count. Access to remote memory on other nodes could be quite slow because it had to go through multiple router hops.
