That's a YES according to PCWatch's review. I'll mention they were using Intel Desktop boards, just to make referencing words used in the BIOS easier.
As long as you have integrated graphics set to "Always" enable, it should allow QuickSync to work even with discrete graphics. They also mention multi-monitor support with the integrated graphics working with discrete
Hmm, apparently, the difference isn't as bad as I expected. I thought performance would be halved but from this review, performance penalty is only around 15% at worst.
Probably because EUs are only part of the pipeline. 2x performance from 2x EUs would indicate serious
design flaw, no one part of the design should be the single source of the bottleneck.
You could compare the transcode pipeline to a CPU pipeline. The front-end on a CPU is similar to the fixed function units doing transcoding in Sandy Bridge, and the EUs are equal to ALUs and FPUs on a CPU.
