...which is why I said it doesn't matter. Intel HD 3000 was the first Intel IGP worth mentioning, and it still paled in comparison to discreet GPUs. Even Intel HD 4000 isn't enough to beat AMD APUs. APUs are fairly weak when it comes to number crunching, but the IGP is based on existing GPU design, which is why it vastly outperforms Intel IGPs.
As for who did it first, I vaguely recall the concept being used on ARM CPUs years before. IIRC, the whole SoC design started around 2003.
EDIT: it's not a pissing contest, it's just that me and Rydian share the basic principle of giving accurate information where possible. None of the BS that keeps popping up on these forums like people saying Anti-Virus suites are unneccessary memory hogs.
