GeForce GTX 650 vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which has GPU core speed of 925 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 650 should perform a bit faster than the Radeon R9 M365X in general. (explain)

GeForce GTX 650		80000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 8000 (11%)

Texel Rate

The Radeon R9 M365X is a bit (approximately 9%) faster with regards to texture filtering than the GeForce GTX 650. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 3144 (9%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 650 is a better choice, though not by far. (explain)

GeForce GTX 650		16928 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 2128 (14%)

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 information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
