Yes, but the 8Gb on-board can be accessed at 320Gb/s whilst the rest of your System RAM can only be accessed by those cores on the PCIe 2.0 card at 16GB/sec. Sounds like a bottleneck, but current modules Peak Transfer Rates are only around 17Gb/s tops, and that's for DDR3-2133 RAM. The bigges= t issue would be=A0 considering the RAM bus would also be the same bus used for Storage writing and reading, and instruction transit. and what memory controller would control those 50 CPUs access to your RAM through your PCIe 2.0 bus.. sounds like it could be a nightmare for applications such as AE with constant I/O and instructions being sent..

I'd hope one day I can just go purchase a $1500-$2000 card, and basically get an internal render-farm.. but I think software would need to catch up to that concept and it would need to go mainstream before we'd really see a lot of applications for it..= =A0 I do see the potential, and it seems to pretty much be a given-future..

Just think.. at some point, there'll probably be configurable RAM options on the CoreBoards, and then we'd need Integrated Video fo= r these CoreBoards..=A0

Basically building a full System Build on a Board that goes in your Full System Build... then you can Cross-fire those boards together in one Case..

Turtles all the way down...

It's my understanding that it will appear as just another processor to the system and thus will share the system's memory= . Those 8GB are more or less just its internal caches.

You might find this interesting.

I do wish it competes directly with GPUs in the future.
