GeForce GTX 460 1GB vs Radeon RX 570

Intro

Compare all of that to the Radeon RX 570, which features GPU clock 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 Stream Processors, 128 TAUs, and 32 ROPs.

Memory Bandwidth

Theoretically speaking, the Radeon RX 570 should be much faster than the GeForce GTX 460 1GB in general. (explain)

Radeon RX 570		229376 MB/sec
GeForce GTX 460 1GB		115200 MB/sec
	Difference: 114176 (99%)

Texel Rate

The Radeon RX 570 will be much (about 296%) more effective at AF than the GeForce GTX 460 1GB. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 570 is a better choice, by far. (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 largest amount of data (measured in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 get to the maximum fill rate.
