GeForce 8800 GS vs GeForce GT 220 GDDR3

Intro

Compare those specifications to the GeForce GT 220 GDDR3, which comes with a core clock frequency of 625 MHz and a GDDR3 memory frequency of 1012 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is made up of 48 SPUs, 16 Texture Address Units, and 8 ROPs.

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GS should perform a small 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 will be much (more or less 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 high levels of AA 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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
