GeForce GTX 965M vs Radeon R9 M370X

Intro

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

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

Texel Rate

The GeForce GTX 965M is quite a bit (more or less 89%) faster with regards to AF than the Radeon R9 M370X. (explain)

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

Pixel Rate

The GeForce GTX 965M will be quite a bit (about 136%) more effective at FSAA than the Radeon R9 M370X, and also will be able to handle higher screen resolutions better. (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 (measured in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
