Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 650 Ti 2GB will be 20% faster than the Radeon R9 M265X overall, because of its greater data rate. (explain)

GeForce GTX 650 Ti 2GB 86400 MB/sec
Radeon R9 M265X 72000 MB/sec
Difference: 14400 (20%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be quite a bit (about 158%) faster with regards to anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 36392 (158%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 650 Ti 2GB is a better choice, by far. (explain)

GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 5648 (61%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
