Geforce GTX 680 vs Radeon RX 470

Intro

Compare all that to the Radeon RX 470, which comes with GPU clock speed of 926 MHz, and 8192 MB of GDDR5 memory running at 1650 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Geforce GTX 680		192256 MB/sec
	Difference: 18944 (10%)

Texel Rate

The Geforce GTX 680 is a little bit (more or less 9%) more effective at AF than the Radeon RX 470. (explain)

Geforce GTX 680		128768 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 10240 (9%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 680 is superior to the Radeon RX 470, but it probably won't make a huge difference. (explain)

Geforce GTX 680		32192 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 2560 (9%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface 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 higher the bandwidth is, the faster 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 are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
