GeForce GTX 560 vs Radeon RX 590

Intro

Compare those specifications to the Radeon RX 590, which comes with a GPU core clock speed of 1469 MHz, and 8192 MB of GDDR5 memory set to run at 2000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 TAUs, and 32 Raster Operation Units.

GeForce GTX 560		128128 MB/sec
	Difference: 134016 (105%)

Texel Rate

The Radeon RX 590 is a lot (more or less 366%) better at texture filtering than the GeForce GTX 560. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 166176 (366%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 590 is superior to the GeForce GTX 560, by far. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX 560		25920 Mpixels/sec
	Difference: 21088 (81%)

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 (in units of MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
