http://www.anandtech.com/show/3871/the-sandy-bridge-preview-three-wins-in-a-row/7The question is how Intel will manage once ~480 shader IGP solutions hit. Brazos, Zacate and Llano are already laying a pounding on Intel's IGPs. We just need a better FLOPs and out-of-order CPU support from AMD to get a clear winner. 20W total is appealing, but I heard it has mobility HD6400 or HD6300 level IGP which arguably match an HD5600 mobility.
Well desktop Sandy Bridge's IGP with pre-release drivers is already comparable to a desktop HD5450, which is a very impressive showing from Intel all things considered. Ivy Bridge looks to double the number of execution units from Sandy Bridge and with other improvements could be looking at more than 2 times the performance of Sandy Bridge's IGP. That would put it close to Llano territory, which is interesting considering Llano doesn't look to ship in volume until Q3 2011, while Ivy Bridge could trickle in at the tail end of 2011. Sandy Bridge has a large CPU advantage over Llano, which will only grow with Ivy Bridge.
2011 AMD Fusion options are not compelling for Apple since Brazos and Zacate are slower both CPU-wise and GPU-wise than the current Penryn Core 2 Duo/320M combo. Llano is too late in the year and doesn't offer competitive CPU performance. Despite all the talk of GPGPU, I think Sandy Bridge's strong CPU and decent IGP is still more beneficial for most users than Llano's decent CPU and strong GPU. Certainly, Apple's focus isn't on gaming where Llano will definitively win out. AVX and even SSE4 support is also absent from Llano, which Apple probably makes heavy use of for multimedia acceleration. AVX also helps Sandy Bridge offset the need for GPGPU. Fusion really looks most compelling in 2012 when AMD should have a strong showing for both the CPU and GPU parts once Bulldozer is integrated.
