GeForce 8800 GT 512MB vs Radeon RX 480

Intro

The GeForce 8800 GT 512MB makes use of a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this specific card. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.

Compare that to the Radeon RX 480, which has a core clock frequency of 1120 MHz and a GDDR5 memory speed of 2000 MHz. It also uses a 256-bit memory bus, and makes use of a 14 nm design. It features 2304 SPUs, 144 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 512MB 105 Watts
Radeon RX 480 150 Watts
Difference: 45 Watts (43%)

Memory Bandwidth

In theory, the Radeon RX 480 will be 355% faster than the GeForce 8800 GT 512MB in general, due to its higher data rate. (explain)

Radeon RX 480 262144 MB/sec
GeForce 8800 GT 512MB 57600 MB/sec
Difference: 204544 (355%)

Texel Rate

The Radeon RX 480 is quite a bit (about 380%) better at anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX 480 161280 Mtexels/sec
GeForce 8800 GT 512MB 33600 Mtexels/sec
Difference: 127680 (380%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 480 is the winner, and very much so. (explain)

Radeon RX 480 35840 Mpixels/sec
GeForce 8800 GT 512MB 9600 Mpixels/sec
Difference: 26240 (273%)

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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is worked out 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 DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
