Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 650 Ti 2GB will be 20% quicker than the Radeon R9 M370X in general, due to its higher data rate. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be quite a bit (about 86%) more effective at AF than the Radeon R9 M370X. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 27392 (86%)

Pixel Rate

The GeForce GTX 650 Ti 2GB will be a bit (about 16%) faster with regards to anti-aliasing than the Radeon R9 M370X, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 2048 (16%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
