The article also suggests the shipping date of Larrabee may be postponed to mid 2011, but provides no reason why Intel might take this decision.
Our source also indicated that Intel is looking to ship Larrabee two years later, putting us in summer of 2011. Of course, by that time, we will have GPUs that are 2 to 4 times faster than current GPUs from both AMD/ATI and Nvidia. However, at that time Larrabee may not be what it is today either.
One critical point we were told was that 1st and 2nd generation Larrabee GPUs will not be compatible with 3rd generation Larrabee. This is of course, highly speculative and very far out. According to the data, Intel's 3rd generation part will have an emulation mode for backwards compatibility. If this is true, then developers would have a hard time programming for Larrabee.
