There's a difference between 7970 "GHZ" and 7950 "Boost" versus a 8950 and a 8930.
One branding option is a lot more deceptive than the other. Take your pick.
There aren't any saints in the rebranding game though. I recall Tom's Hardware pitted a Radeon 6990m against a desktop 6970, and the 6990. The mobile version was more on par with CF of underclocked 6870s in pure performance.
And Intel seems to really love to stick "i7" brands onto ULV dual-core CPUs.
