GeForce 8800 GS vs GeForce GT 220 GDDR3

Intro

The GeForce 8800 GS makes use of a 65 nm design. nVidia has set the core speed at 550 MHz. The GDDR3 memory works at a speed of 800 MHz on this particular model. It features 96 SPUs as well as 48 Texture Address Units and 12 ROPs.

Compare those specifications to the GeForce GT 220 GDDR3, which comes with a core clock speed of 625 MHz and a GDDR3 memory frequency of 1012 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 48 SPUs, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 220 GDDR3 58 Watts
GeForce 8800 GS 105 Watts
Difference: 47 Watts (81%)

Memory Bandwidth

Theoretically, the GeForce 8800 GS should be just a bit faster than the GeForce GT 220 GDDR3 overall. (explain)

GeForce 8800 GS 38400 MB/sec
GeForce GT 220 GDDR3 32384 MB/sec
Difference: 6016 (19%)

Texel Rate

The GeForce 8800 GS should be quite a bit (approximately 164%) better at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

GeForce 8800 GS 26400 Mtexels/sec
GeForce GT 220 GDDR3 10000 Mtexels/sec
Difference: 16400 (164%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 8800 GS is superior to the GeForce GT 220 GDDR3, by far. (explain)

GeForce 8800 GS 6600 Mpixels/sec
GeForce GT 220 GDDR3 5000 Mpixels/sec
Difference: 1600 (32%)

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 largest amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
