Geforce GTX 780 vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which makes use of a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 memory works at a speed of 1750 MHz on this card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

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

Texel Rate

The Geforce GTX 780 is quite a bit (about 171%) faster with regards to AF 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

The Geforce GTX 780 will be quite a bit (approximately 138%) better at anti-aliasing than the Radeon RX 460 2GB, and will be capable of handling higher screen resolutions better. (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: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
