GeForce 8800 GTS (G92) vs GeForce 9800 GT 1GB

Intro

Compare that to the GeForce 9800 GT 1GB, which comes with a clock speed of 600 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit memory bus, and makes use of a 65/55 nm design. It is comprised of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GT 1GB		105 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 30 Watts (29%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GTS (G92) is 8% quicker than the GeForce 9800 GT 1GB overall, because of its greater data rate. (explain)

GeForce 8800 GTS (G92)		62080 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 4480 (8%)

Texel Rate

The GeForce 8800 GTS (G92) is quite a bit (more or less 24%) more effective at anisotropic filtering than the GeForce 9800 GT 1GB. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 8000 (24%)

Pixel Rate

The GeForce 8800 GTS (G92) will be a bit (more or less 8%) better at full screen anti-aliasing than the GeForce 9800 GT 1GB, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 8800 GTS (G92)		10400 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 800 (8%)

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 megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied 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 higher the texel rate, the better the video 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 most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
