GeForce GTX 460 2GB vs Radeon RX 460

Intro

Compare those specifications to the Radeon RX 460, which comes with a core clock frequency of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit bus, and makes use of a 14 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Radeon RX 460		112000 MB/sec
	Difference: 3200 (3%)

Texel Rate

The Radeon RX 460 should be much (about 61%) more effective at texture filtering than the GeForce GTX 460 2GB. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 23240 (61%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 2GB is the winner, by far. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 4160 (24%)

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 (counted in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type 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 faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 the graphics 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
