Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti 2GB will be 20% faster than the Radeon R9 M270X overall, due to its greater bandwidth. (explain)

GeForce GTX 650 Ti 2GB 86400 MB/sec
Radeon R9 M270X 72000 MB/sec
Difference: 14400 (20%)

Texel Rate

The GeForce GTX 650 Ti 2GB is quite a bit (about 105%) faster with regards to AF than the Radeon R9 M270X. (explain)

GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
Radeon R9 M270X 29000 Mtexels/sec
Difference: 30392 (105%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 650 Ti 2GB is superior to the Radeon R9 M270X, and very much so. (explain)

GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
Radeon R9 M270X 11600 Mpixels/sec
Difference: 3248 (28%)

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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
