GeForce GTX 460 1GB vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which comes with clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Radeon RX 560		114688 MB/sec
	Difference: 512 (0%)

Texel Rate

The Radeon RX 560 should be a lot (more or less 99%) faster with regards to texture filtering than the GeForce GTX 460 1GB. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 37400 (99%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 460 1GB is superior to the Radeon RX 560, though only just barely. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 2800 (15%)

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 largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
