GeForce GTX 965M vs Radeon R9 M375X

Intro

The GeForce GTX 965M makes use of a 28 nm design. nVidia has set the core speed at 944 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this particular card. It features 1024 SPUs along with 64 Texture Address Units and 32 ROPs.

Compare those specifications to the Radeon R9 M375X, which comes with core speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X should be just a bit faster than the GeForce GTX 965M overall. (explain)

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

Texel Rate

The GeForce GTX 965M is quite a bit (approximately 49%) faster with regards to AF than the Radeon R9 M375X. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 965M is a better choice, and very much so. (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 max amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
