GeForce 8800 GTS (G92) vs GeForce GT 340 1GB

Intro

Compare that to the GeForce GT 340 1GB, which has a core clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It is made up of 96 SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340 1GB		69 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 66 Watts (96%)

Memory Bandwidth

Performance-wise, the GeForce 8800 GTS (G92) should in theory be just a bit superior to the GeForce GT 340 1GB in general. (explain)

GeForce 8800 GTS (G92)		62080 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 7680 (14%)

Texel Rate

The GeForce 8800 GTS (G92) should be a lot (more or less 136%) more effective at anisotropic filtering than the GeForce GT 340 1GB. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 24000 (136%)

Pixel Rate

The GeForce 8800 GTS (G92) is much (more or less 136%) more effective at AA than the GeForce GT 340 1GB, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 8800 GTS (G92)		10400 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 6000 (136%)

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 max amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
