GeForce GTX 470 vs Radeon RX 460

Intro

The GeForce GTX 470 features a core clock speed of 607 MHz and a GDDR5 memory speed of 837 MHz. It also uses a 320-bit memory bus, and uses a 40 nm design. It features 448 SPUs, 56 TAUs, and 40 Raster Operation Units.

Compare all of that to the Radeon RX 460, which has GPU clock speed of 1090 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.

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

Pixel Rate

The GeForce GTX 470 should be quite a bit (approximately 39%) better at full screen anti-aliasing than the Radeon RX 460, and should be capable of handling higher screen resolutions better. (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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
