100% agreed. We might have been on the same team. Don't forget Omnipath and Xeon Phi. Prediction: this new discrete graphics card as well.

- shaklee3 7y agoOmnipath went the way infiniband is going. Ethernet has caught up, and surpassed the speeds, so using proprietary technology with fewer features isn't that attractive anymore.
- sitkack 7y agohttps://en.wikipedia.org/wiki/Terabit_Ethernet https://en.wikipedia.org/wiki/Terabit_Ethernet is faster than the main memory bandwidth on current generation processors.
- vardump 7y agoBut not faster than L3 cache bandwidth. Some cards can DMA to L3 cache. Granted, eventually it's flushed to main RAM, so might not help too much in the end.
- sitkack 7y agoCool. That means it both prevents nethammer and allows the cpu to check a signature/decrypt/type check as value stream over the network.
- porker 7y agoI sat through a Xeon Phi presentation at university, about how it would revolutionize the university's "supercomputer". I left shortly after; did Phi come to nothing?
- pinewurst 7y agoIt was too difficult to get decent performance from Xeon Phi for general use cases. A few apps could make it work e.g. PGS bought up all the old stock for a big geophysics system.
