GeForce GTX 560 vs Radeon RX 580

Intro

The GeForce GTX 560 has a GPU core speed of 810 MHz, and the 1024 MB of GDDR5 RAM runs at 1001 MHz through a 256-bit bus. It also is made up of 336 Stream Processors, 56 Texture Address Units, and 32 Raster Operation Units.

Compare those specs to the Radeon RX 580, which uses a 14 nm design. AMD has set the core speed at 1257 MHz. The GDDR5 memory runs at a frequency of 2000 MHz on this model. It features 2304 SPUs along with 144 Texture Address Units and 32 ROPs.

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

Texel Rate

The Radeon RX 580 should be a lot (approximately 299%) more effective at anisotropic filtering than the GeForce GTX 560. (explain)

Radeon RX 580 181008 Mtexels/sec
GeForce GTX 560 45360 Mtexels/sec
Difference: 135648 (299%)

Pixel Rate

The Radeon RX 580 will be quite a bit (approximately 55%) more effective at FSAA than the GeForce GTX 560, and also able to handle higher resolutions while still performing well. (explain)

Radeon RX 580 40224 Mpixels/sec
GeForce GTX 560 25920 Mpixels/sec
Difference: 14304 (55%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 can be processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the 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 card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
