GeForce GTX 460 (OEM) vs Radeon RX 570

Intro

Compare that to the Radeon RX 570, which comes with a core clock frequency of 1168 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 256-bit memory bus, and makes use of a 14 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 570 should be much faster than the GeForce GTX 460 (OEM) in general. (explain)

Radeon RX 570		229376 MB/sec
GeForce GTX 460 (OEM)		108800 MB/sec
	Difference: 120576 (111%)

Texel Rate

The Radeon RX 570 should be quite a bit (more or less 311%) faster with regards to AF than the GeForce GTX 460 (OEM). (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 113104 (311%)

Pixel Rate

The Radeon RX 570 is much (approximately 80%) faster with regards to FSAA than the GeForce GTX 460 (OEM), and also capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GTX 460 (OEM)		20800 Mpixels/sec
	Difference: 16576 (80%)

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 maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
