GeForce 8800 GT 1GB vs GeForce GTS 250 1GB

Intro

The GeForce 8800 GT 1GB comes with a clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit bus, and uses a 65 nm design. It is comprised of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Compare all of that to the GeForce GTS 250 1GB, which comes with a clock speed of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also features a 256-bit bus, and makes use of a 65/55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB 105 Watts
GeForce GTS 250 1GB 145 Watts
Difference: 40 Watts (38%)

Memory Bandwidth

Theoretically speaking, the GeForce GTS 250 1GB will be 22% faster than the GeForce 8800 GT 1GB overall, due to its greater bandwidth. (explain)

GeForce GTS 250 1GB 70400 MB/sec
GeForce 8800 GT 1GB 57600 MB/sec
Difference: 12800 (22%)

Texel Rate

The GeForce GTS 250 1GB should be a lot (approximately 41%) better at AF than the GeForce 8800 GT 1GB. (explain)

GeForce GTS 250 1GB 47232 Mtexels/sec
GeForce 8800 GT 1GB 33600 Mtexels/sec
Difference: 13632 (41%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTS 250 1GB is the winner, and very much so. (explain)

GeForce GTS 250 1GB 11808 Mpixels/sec
GeForce 8800 GT 1GB 9600 Mpixels/sec
Difference: 2208 (23%)

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 information (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
