GeForce 8800 GTS (G92) vs GeForce GTS 250 1GB

Intro

The GeForce 8800 GTS (G92) makes use of a 65 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 RAM is set to run at a frequency of 970 MHz on this card. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTS 250 1GB, which features a clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also uses a 256-bit bus, and uses a 65/55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

GeForce 8800 GTS (G92) 62080 MB/sec
Difference: 8320 (13%)

Texel Rate

The GeForce GTS 250 1GB is a little bit (about 14%) more effective at texture filtering than the GeForce 8800 GTS (G92). (explain)

GeForce GTS 250 1GB 47232 Mtexels/sec
GeForce 8800 GTS (G92) 41600 Mtexels/sec
Difference: 5632 (14%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTS 250 1GB is superior to the GeForce 8800 GTS (G92), though not by far. (explain)

GeForce GTS 250 1GB 11808 Mpixels/sec
GeForce 8800 GTS (G92) 10400 Mpixels/sec
Difference: 1408 (14%)

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 data (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
