GeForce 8800 Ultra vs Radeon RX 560

Intro

Compare that to the Radeon RX 560, which features GPU clock speed of 1175 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

GeForce 8800 Ultra		103680 MB/sec
	Difference: 11008 (11%)

Texel Rate

The Radeon RX 560 is a lot (approximately 92%) better at AF than the GeForce 8800 Ultra. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 36032 (92%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 560 is superior to the GeForce 8800 Ultra, by far. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 4112 (28%)

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 information (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
