GeForce GTX 965M vs Radeon R9 M375X

Intro

The GeForce GTX 965M features a GPU core speed of 944 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1000 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 TAUs, and 32 ROPs.

Compare those specs to the Radeon R9 M375X, which has core clock speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

GeForce GTX 965M 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The GeForce GTX 965M will be much (more or less 49%) better at anisotropic 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 is much (more or less 86%) faster with regards to AA than the Radeon R9 M375X, and also capable of handling higher screen resolutions while still performing well. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at 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 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 number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
