GeForce GTX 460 1GB vs Radeon RX 570

Intro

Compare that to the Radeon RX 570, which has GPU core speed of 1168 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Radeon RX 570		149504 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 111704 (296%)

Pixel Rate

The Radeon RX 570 should be much (approximately 73%) more effective at FSAA than the GeForce GTX 460 1GB, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GTX 460 1GB		21600 Mpixels/sec
	Difference: 15776 (73%)

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 (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
