GeForce GTX 950 vs Radeon R9 M280X

Intro

The GeForce GTX 950 has a GPU clock speed of 1024 MHz, and the 2048 MB of GDDR5 memory is set to run at 1652 MHz through a 128-bit bus. It also features 768 SPUs, 48 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon R9 M280X, which has clock speeds of 900 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs along with 56 TAUs and 16 ROPs.

GeForce GTX 950 105728 MB/sec
Radeon R9 M280X 88000 MB/sec
Difference: 17728 (20%)

Texel Rate

The Radeon R9 M280X will be a little bit (about 3%) faster with regards to anisotropic filtering than the GeForce GTX 950. (explain)

Radeon R9 M280X 50400 Mtexels/sec
GeForce GTX 950 49152 Mtexels/sec
Difference: 1248 (3%)

Pixel Rate

The GeForce GTX 950 is a lot (more or less 128%) more effective at anti-aliasing than the Radeon R9 M280X, and also should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 950 32768 Mpixels/sec
Radeon R9 M280X 14400 Mpixels/sec
Difference: 18368 (128%)

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: Bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels the video card could possibly record 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 card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
