Thanks, that's very useful. I figured when they say mainstream in that image, they were talking about me since I tend to stay away from cutting edge tech, instead aiming for whatever the tomshardware/anandtech's of the world tout as the price/performance sweet spot at the time. But if the IPU on the Llano doesn't provide any value to someone who would have a discrete GPU, kind of feel's I'm paying for a feature I'll never use.Shubit said:Llano (which uses AMD's current K10.5 microarchitecture) has the IGP and PCIe controller integrated ondie and uses completely different chipsets than the upcoming Bulldozer based CPUs codenamed Zambezi. The Zambezi lineup is compatible with AMD's GX line of chipsets that provide integrated graphics should you desire to use them.
Llano has supposedly already shipped to system integrators (think Dell). As to it's availability in retail, nobody but AMD knows yet.
When you use a discrete GPU the motherboard BIOS usually automatically disables the IGP unless you set the option otherwise in the BIOS. The IGP and the discrete GPU can complement each other in a mode called Hybrid CrossFire but it's rather poor since your choice of discrete GPU is limited to ones that are architecture and speed wise similar to the onboard one. Since even top end integrated graphics are usually based on previous generation discrete chips of the mainstream market segment (not exactly gamers choice), HCF is not of much use to anyone.
Although I might have sparked interest by praising the possibility of accelerated processing above, note that the practical reality of it is still a year or two off. If you are after a high end workstation/gaming computer right now, you are better off by going with either a Bulldozer or SB based setup. For Bulldozer I recommend waiting for upcoming 900 series chipsets which are critical for enabling some of the new integral CPU features like core powergating and also bring SLI support (yippie kay yay finally).
Llano on the other hand will absolutely dominate in things like iMac or HTPC.
It's disappointing that onboard/ondie graphics processing doesn't better complement discrete cards, but I figured it was a bit of a pipe dream and terribly complicated for companies to pull off. Nice to have a slightly better understanding of the how and why, though.
