The longest path in a 100 GHz chip would be 3 mm or a signal travelling at the speed of light won't have enough time to reach the other endpoint.

- wmf 17y agoSee sparky's comment; 100 GHz transistors allow you to build a ~10 GHz chip. Even at 2 GHz, NetBurst struggled with wire delay back in 2000.
- andreyf 17y ago<3mm cores might be a great idea - as multicore programming evolves, this may make possible thousands or millions of cores running at very high clock speeds.
- wmf 17y agoTilera's "KILL" cores are probably a bit under 3 mm x 3 mm, although I don't think massive multicore is a good idea for many applications. http://gamma.cs.unc.edu/EDGE/SLIDES/agarwal.pdf http://gamma.cs.unc.edu/EDGE/SLIDES/agarwal.pdf
- andreyf 17y agoI don't think massive multicore is a good idea for many applications But hey now, that's the problem of the applications, isn't it? There's probably quite a bit of exciting potential with what you can do with massive multicore architecture - slide 6 of the presentation you linked to being a very convincing reason why.
