The answer could be simple. If you use 2CU/4C, there are 2 floating point units available, in 4CU/4C mode 4. So a task using 4 cores, gets access to 4 vs. 2 fpus. The performance gain in 50% int and 50 % fpu scenarios, is up to 25 %. Xbox ported games, mostly use 2 cores. So they get access to 2 fpus in both scenarios and you see performance gain of about 5 % only, from doubled cache per core.

Console ports are not the problem, there is always enough power for a FX6 or FX8 to reach >60 fps. The problem is Dirt, F1, Civ5, Crysis 2,... . Northbridge overclocking and 4CU/4C can be the difference between playable or not.
