That may explain why intel has put a 1/2 bandwidth PCIe controller on the Lynnfield. It probably saves die space, and does not negatively impact Larrabee (but will negatively impact AMD/NV GPUs).
That's pretty underhanded, especially in light of the massive antitrust settlement in Europe. This one is simply blatant IMO.
Interesting. I didn't think of that. Make Nvidia and AMD users buy the most expensive board in order to get full bandwidth for their video cards and offer Larrabee on the cheaper boards. It will make Larrabee even more attractive price vs. performance. And that would force AMD and Nvidia into making chipsets to get that bandwidth back. We'll see if that is part of their strategy with this move.
Yeah, I'm guessing that the Larrabee could benefit 20-30% or more from the on-die PCIe controller as well due to the reduced latency. I have a feeling that it's going to be really lopsided. I could see Larrabee winning a few benchmarks on an i5 motherboard, then losing them all on a different motherboard, and vice versa.
Intel is doing everything that they can to boost Larrabee's performance as they appear to be at a 50% transistor disadvantage by default.
How does that give Intel an advantage? Larrabee would look better than Nvidia and ATI on an Intel board, but the Intel board would be destroyed by an AMD board using the exact same video cards. There's no way Intel would screw themselves like that.
