GeForce 8800 Ultra vs Radeon RX 560

Intro

The GeForce 8800 Ultra makes use of a 90 nm design. nVidia has clocked the core speed at 612 MHz. The GDDR3 RAM works at a speed of 1080 MHz on this model. It features 128 SPUs as well as 64 TAUs and 24 ROPs.

Compare that to the Radeon RX 560, which features a clock speed of 1175 MHz and a GDDR5 memory frequency of 7000 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is made up of 1024 SPUs, 64 TAUs, and 16 ROPs.

Power Consumption (Max TDP)

Radeon RX 560 80 Watts
GeForce 8800 Ultra 171 Watts
Difference: 91 Watts (114%)

Memory Bandwidth

In theory, the Radeon RX 560 should be 11% faster than the GeForce 8800 Ultra in general, due to its greater data rate. (explain)

Radeon RX 560 114688 MB/sec
GeForce 8800 Ultra 103680 MB/sec
Difference: 11008 (11%)

Texel Rate

The Radeon RX 560 should be a lot (about 92%) more effective at texture filtering than the GeForce 8800 Ultra. (explain)

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

Pixel Rate

The Radeon RX 560 will be a lot (about 28%) faster with regards to anti-aliasing than the GeForce 8800 Ultra, and also capable of handling higher resolutions without losing too much performance. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
