GeForce GTX 460 SE vs Radeon RX 570

Intro

Compare those specs to the Radeon RX 570, which features core clock speeds of 1168 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 570 will be 111% quicker than the GeForce GTX 460 SE in general, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 570 should be a lot (about 379%) more effective at texture filtering than the GeForce GTX 460 SE. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 118304 (379%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 570 is the winner, and very much so. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GTX 460 SE		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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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