GeForce GTX 965M vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which features a core clock frequency of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M370X should theoretically perform a bit faster than the GeForce GTX 965M overall. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce GTX 965M		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The GeForce GTX 965M should be quite a bit (approximately 89%) more effective at anisotropic filtering than the Radeon R9 M370X. (explain)

GeForce GTX 965M		60416 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 28416 (89%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 965M is a better choice, by far. (explain)

GeForce GTX 965M		30208 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 17408 (136%)

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 maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
