GeForce 8800 GT 512MB vs Radeon RX 480

Intro

The GeForce 8800 GT 512MB comes with a clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit bus, and uses a 65 nm design. It is made up of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.

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

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

Pixel Rate

The Radeon RX 480 is much (approximately 273%) faster with regards to anti-aliasing than the GeForce 8800 GT 512MB, and also will be able to handle higher resolutions while still performing well. (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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
