GeForce GTX 965M vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which comes with GPU core speed of 1015 MHz, and 4096 MB of DDR3 memory set to run at 1100 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 ROPs.

Radeon R9 M375		35200 MB/sec
	Difference: 28800 (82%)

Texel Rate

The GeForce GTX 965M is much (approximately 49%) better at texture filtering than the Radeon R9 M375. (explain)

GeForce GTX 965M		60416 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 19816 (49%)

Pixel Rate

The GeForce GTX 965M will be quite a bit (more or less 86%) better at AA than the Radeon R9 M375, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 965M		30208 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 13968 (86%)

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 (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, 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 most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
