GeForce GTX 950M vs Radeon R9 M365X

Intro

The GeForce GTX 950M features core clock speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon R9 M365X, which uses a 28 nm design. AMD has set the core speed at 925 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 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M365X should be 125% quicker than the GeForce GTX 950M in general, due to its greater data rate. (explain)

Radeon R9 M365X 72000 MB/sec
GeForce GTX 950M 32000 MB/sec
Difference: 40000 (125%)

Texel Rate

The Radeon R9 M365X is a little bit (about 1%) better at anisotropic filtering than the GeForce GTX 950M. (explain)

Radeon R9 M365X 37000 Mtexels/sec
GeForce GTX 950M 36560 Mtexels/sec
Difference: 440 (1%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M365X is the winner, not by a very large margin though. (explain)

Radeon R9 M365X 14800 Mpixels/sec
GeForce GTX 950M 14624 Mpixels/sec
Difference: 176 (1%)

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 transferred across the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the 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 maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
