How do I test memory transfer rates?
Is there a benchmark program that can test my video cards memory
transfer rate?

How do I test memory transfer rates?
I haven't seen one. And even if such a program existed, its usefulness would
be questionable at best. Real-world performance depends on the memory controller design. For example, a 4x32-bit "crossbar" interface is faster than an 1x128-bit interface in most games, even though the theoretical transfer rates are identical. Other significant factors include memory timings, color/Z-buffer compression, and hidden-surface removal (think Geforce 8800's Early-Z or Radeon's Hyper-Z). On the other hand, if all you need to do is confirm, for example, your card has a full 128-bit memory interface rather than a cut-down 64-bit "LE" interface, then a program like Everest will tell you. -- "War is the continuation of politics by other means. It can therefore be said that politics is war without bloodshed while war is politics with bloodshed." wrote in message oups.com...

How do I test memory transfer rates?
The "measurement" of memory bandwidth, as written in reviews, is always
calculated theoretically. For example, a card with a 256-bit memory interface, with the RAM running at 1.2 GHz effective, would have 256 x 1.2 / 8 = 38 GB/s of memory bandwidth. -- "War is the continuation of politics by other means.

How do I test memory transfer rates?
I am sure there are small simple programs. However, again, such benchmarks
bear no resemblance to real-world gameplay. Even the large 3DMark suite stopped being realistic after the 2001 edition. There's a burn-in function in ATiTool, with a frame-per-second display. Consider it the simplest benchmark available. :-) -- "War is the continuation of politics by other means.
