Geforce GTX 780 vs Radeon RX 460 2GB

Intro

Compare those specifications to the Radeon RX 460 2GB, which has clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
Geforce GTX 780		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 780 should be 157% quicker than the Radeon RX 460 2GB in general, because of its greater bandwidth. (explain)

Geforce GTX 780		288384 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 176384 (157%)

Texel Rate

The Geforce GTX 780 should be much (more or less 171%) better at texture filtering than the Radeon RX 460 2GB. (explain)

Geforce GTX 780		165696 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 104656 (171%)

Pixel Rate

If running with a high screen resolution is important to you, then the Geforce GTX 780 is a better choice, and very much so. (explain)

Geforce GTX 780		41424 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 23984 (138%)

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: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
