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

Intro

Compare all that to the GeForce GTS 250 1GB, which has a GPU core clock speed of 738 MHz, and 1024 MB of GDDR3 memory running at 1100 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTS (G92)		135 Watts
GeForce GTS 250 1GB		145 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

In theory, the GeForce GTS 250 1GB will be 13% faster than the GeForce 8800 GTS (G92) in general, due to its greater bandwidth. (explain)

GeForce GTS 250 1GB		70400 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 8320 (13%)

Texel Rate

The GeForce GTS 250 1GB is a little bit (more or less 14%) better 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 running with lots of anti-aliasing is important to you, then the GeForce GTS 250 1GB is a better choice, but it probably won't make a huge difference. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, 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 that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
