Speed gains from the integrated PCIe controller in the FM1 Athlons ?

[William Gaatjes]

Hello, i am curious how much benefit there is from the integrated PCIe controller for FM1 athlons and Liano ?
I vaguely recall that at the time when Intel released Lynnfield, there was a significant boost in game speed due to the integration of the PCIe controller directly onto the cpu die. This reduced latency a lot since now the GPU only "sees" the PCIe controller ,a crossbar multiplexer and then the memory controller to access main memory :The FSB(quickpath) connection was no longer there.

Now AMD has done the same with removing the hypertransport link out of the equation. But i find it difficult to find information about how the new Athlon II models and Liano models (Both FM1) gain from this small change in architecture. Has anybody some good information about this ?

I have read somewhere that the A75 chipset only consumes a maximum of 8 watts of electrical power. That is a good thing indeed.

A big difference,, memory reads and writes will be much faster..... gl

I mentioned FSB in the first post, but i must clarify that Intel since nehalem presented the quickpath interconnect.
