64MB vs. 128MB - Equivalent Clock Speeds

For the next test we wanted to isolate the difference in memory size alone, so we left both cards at the same 250MHz memory clock speed. The results were as follows:

With UPT being very GPU limited, an increase in memory bandwidth doesn't help much. Unreal Tournament 2003 will definitely benefit from a faster memory clock and the additional 64MB of memory however.

Jedi Knight 2 is already able to show a good performance benefit from more local memory.
