GeForce 8800 GS vs GeForce GT 340 1GB

Intro

Compare all of that to the GeForce GT 340 1GB, which comes with core clock speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 96 SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340 1GB		69 Watts
GeForce 8800 GS		105 Watts
	Difference: 36 Watts (52%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 340 1GB will be 42% quicker than the GeForce 8800 GS overall, due to its higher bandwidth. (explain)

GeForce GT 340 1GB		54400 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 16000 (42%)

Texel Rate

The GeForce 8800 GS should be a lot (more or less 50%) faster with regards to texture filtering than the GeForce GT 340 1GB. (explain)

GeForce 8800 GS		26400 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 8800 (50%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 8800 GS is a better choice, and very much so. (explain)

GeForce 8800 GS		6600 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 2200 (50%)

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 largest amount of information (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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