With the graphics benchmarks out of the way, let’s consider CPU clock speed scaling:
Even a 2.0 GHz Phenom II X4 can drive Rage without bottlenecking performance at 1080p, maximum details, and 4x anti-aliasing. This does make some sense, though, as id coded this game for comparatively slow consoles and then ported it over to run on PCs.
Let’s lower the number of execution cores and see if that makes any difference.
Apparently not. A dual-core Phenom II X2 at 3.0 GHz handles the game just fine. We’ve never before seen a game that looks this good, but requires so little processing horsepower. That's what happens when developers write for the lowest common denominator, folks. We have to wonder how much more could have been done with this game if it were written for the PC.
