Hi guys, my 1st post here but i had to sign up and ask a question if i may ?
There is clearly a lot of well informed guys here so my thinking is who better to ask so..
Talking from the POV of a desktop cpu for a HTPC and on chip gpu, doesn't it seem strange that the broadwell has GT4e @ 128mb cache in that the new skylake will only have GT4e @ 64mb and again with kaby lake, although i do see a mobile there with GT4e & 2x 128mb it's not desktop, it looks like a step backwards to me, to top it off it's over two upcoming chips with nothing matching the broadwell igpu.
Am i missing something here?
Well, Skylake does have DDR4 memory support. The faster DRAM should help the performance of the memory subsystem, and reduce the need for the eDRAM cache.
But also, I suspect that they are running against the limitation of what they can physically fit on the package. If Skylake is a bigger chip than Broadwell, they may need to use a smaller eDRAM chip to fit both of them under the heat spreader.
