He could be saying that the HD series is the best of integrated, which is true; as the HD series has improved with processor generations:
GMA950<HD2000<HD2500< HD3000< HD4000< HD4600
These are all intel's integrated graphics solutions.
My old GMA950 that was with the Core 2 Duo was far slower than even the geforce 210, which is widely accepted as the slowest graphics card that is still used. I'm told the HD 4600 that's come with my laptop's i5 processor is faster than the 210, and I have tested it to confirm that it's true.
