What is the texture loading speed?

I would like to load two images into the GPU memory, and I wonder how fast can I do this?

In fact - will it be faster to compare two bitmaps in RAM with the processor or load them on the GPU and use parallelism GPU for this?

If you run the sample bandwidth of the CUDA device, you will get a guide to download speed.

Assuming DDR3 is a three-channel RAM with a frequency of 1600 MHz, you get about 38 GB / s of memory.

However, I think that in the general case (for example, with busspeeds in GB / s order) it is faster to upload images to the GPU and compare differences there.
