GeForce GTX 650 vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 650 should perform a little 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 small bit (about 6%) more effective 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

The GeForce GTX 650 should be quite a bit (about 32%) faster with regards to AA than the Radeon R9 M370X, and also should be capable of handling higher screen resolutions better. (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 max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total 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 processed in a 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 calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of 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.
