- It depends what data is moved.
-
- If you copy bitmap data, 64bit is 2 times faster than 32bit.
- If you do 256 color texture-mapping, 64bit isn't much faster as 8bit,
- as you read pixelwise from source texture.
-
- It's same with lot of counter variables or whatever, they only need
- 32bit so a 64bit integer isn't any faster but needs more mem.
