Geforce GTX 780 vs Radeon RX 460 2GB

Intro

Compare those specs to the Radeon RX 460 2GB, which makes use of a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this specific card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

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

Memory Bandwidth

In theory, the Geforce GTX 780 should be quite a bit faster than the Radeon RX 460 2GB overall. (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 quite a bit (approximately 171%) more effective at 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 is much (more or less 138%) faster with regards to FSAA than the Radeon RX 460 2GB, and also should be capable of handling higher resolutions without slowing down too much. (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 maximum amount of data (measured in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
