Hi David,

The article is simply excellent. Thank You for very good and hard work.

I'd add few words regarding the speculation part. Most probably we can expect first Intel attempt to put CPU and GPU in one package as multi-die solution (like Presler, Kentsfield, etc. - same is expected for AMD Fusion) and the think which make me wonder is whenever it is better to integrate memory controler with CPU-die or GPU-die?

Moving it to GPU-die looks like natural consequence - it could be even "cut-down" northbridge with CSI ports. However memory controller in CPU-die would reduce latency for CPU and GPU will rather not suffer too much about it (it rather need lots of bandwidth). The drawback of such approach is that we will have quite a lot of traffic between CPU and GPU. Both approaches seem to possible - even a mixed variant (1 channel for CPU, 1 for GPU), but I don't think that it will go that way.

Once again - thank You for excellent article - it was pleasure to read.

Best regards,
Marcin N.
