GeForce GTX 470 vs Radeon RX 460

Intro

The GeForce GTX 470 makes use of a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 RAM is set to run at a frequency of 837 MHz on this card. It features 448 SPUs along with 56 TAUs and 40 ROPs.

Compare those specs to the Radeon RX 460, which comes with a GPU core clock speed of 1090 MHz, and 4096 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also features 896 SPUs, 56 TAUs, and 16 ROPs.

Radeon RX 460 112000 MB/sec
Difference: 21920 (20%)

Texel Rate

The Radeon RX 460 will be quite a bit (more or less 80%) better at AF than the GeForce GTX 470. (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 27048 (80%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 470 is a better choice, by a large margin. (explain)

GeForce GTX 470 24280 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 6840 (39%)

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 (measured in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
