GeForce 8800 GTX vs Radeon RX 560

Intro

The GeForce 8800 GTX comes with a GPU core clock speed of 575 MHz, and the 768 MB of GDDR3 RAM runs at 900 MHz through a 384-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 24 Raster Operation Units.

Compare all of that to the Radeon RX 560, which comes with GPU core speed of 1175 MHz, and 4096 MB of GDDR5 RAM set to run at 7000 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

GeForce 8800 GTX 86400 MB/sec
Difference: 28288 (33%)

Texel Rate

The Radeon RX 560 will be quite a bit (approximately 104%) better at anisotropic filtering than the GeForce 8800 GTX. (explain)

Radeon RX 560 75200 Mtexels/sec
GeForce 8800 GTX 36800 Mtexels/sec
Difference: 38400 (104%)

Pixel Rate

The Radeon RX 560 should be a lot (approximately 36%) better at AA than the GeForce 8800 GTX, and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 560 18800 Mpixels/sec
GeForce 8800 GTX 13800 Mpixels/sec
Difference: 5000 (36%)

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 max amount of information (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
