GeForce GTX 650 vs Radeon R9 M370X

Intro

Compare that to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650, in theory, should be just a bit faster than the Radeon R9 M370X overall. (explain)

GeForce GTX 650		80000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 8000 (11%)

Texel Rate

The GeForce GTX 650 should be a little bit (more or less 6%) better at anisotropic filtering than the Radeon R9 M370X. (explain)

GeForce GTX 650		33856 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 1856 (6%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 650 is the winner, and very much so. (explain)

GeForce GTX 650		16928 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 4128 (32%)

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: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics 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 number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
