GeForce GTX 950 vs Radeon RX 460

Intro

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

Compare those specifications to the Radeon RX 460, which comes with a core clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and makes use of a 14 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

GeForce GTX 950 105728 MB/sec
Difference: 6272 (6%)

Texel Rate

The Radeon RX 460 is quite a bit (about 24%) better at texture filtering than the GeForce GTX 950. (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GTX 950 49152 Mtexels/sec
Difference: 11888 (24%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 950 is a better choice, and very much so. (explain)

GeForce GTX 950 32768 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 15328 (88%)

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 maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core 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 that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's 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 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.
