Some Intel Haswell chips to get 64MB onboard memory?

According to Demerjian, "GT3 variants" of Haswell will have a whopping 64MB of memory sitting right on the CPU package, next to the processor die. That memory will purportedly be enough to accommodate a frame buffer, which should help alleviate performance bottlenecks tied to the main memory interface. Earlier reports suggest desktop variants of Haswell will have a dual-channel DDR3 memory controller, and there's only so much bandwidth you can get out of that.

In another story posted earlier this year, Demerjian said Haswell's integrated GPU will have five times the shader performance of Sandy Bridge's IGP. Coupled with the onboard memory, that ought to make for some substantial performance improvements—provided this is all true, of course.
