GeForce 8800 GTS (G92) vs GeForce GTX 550 Ti

Intro

Compare all of that to the GeForce GTX 550 Ti, which makes use of a 40 nm design. nVidia has clocked the core frequency at 900 MHz. The GDDR5 memory works at a speed of 1026 MHz on this particular card. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 550 Ti should be a lot faster than the GeForce 8800 GTS (G92) in general. (explain)

GeForce GTX 550 Ti		98496 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 36416 (59%)

Texel Rate

The GeForce 8800 GTS (G92) will be quite a bit (more or less 44%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 12800 (44%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is superior to the GeForce 8800 GTS (G92), by far. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 11200 (108%)

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 information (in units of MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
