GeForce GTX 965M vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which uses a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X should theoretically perform just a bit faster than the GeForce GTX 965M in general. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GTX 965M		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The GeForce GTX 965M is much (approximately 49%) better at texture filtering than the Radeon R9 M375X. (explain)

GeForce GTX 965M		60416 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 19816 (49%)

Pixel Rate

The GeForce GTX 965M will be a lot (more or less 86%) more effective at AA than the Radeon R9 M375X, and should be capable of handling higher resolutions better. (explain)

GeForce GTX 965M		30208 Mpixels/sec
Radeon R9 M375X		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 maximum amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video 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 maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
