GeForce 8800 Ultra vs GeForce GT 340

Intro

Compare that to the GeForce GT 340, which comes with GPU clock speed of 550 MHz, and 512 MB of GDDR5 RAM set to run at 850 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 32 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
GeForce 8800 Ultra		171 Watts
	Difference: 102 Watts (148%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 Ultra is 91% faster than the GeForce GT 340 in general, due to its higher data rate. (explain)

GeForce 8800 Ultra		103680 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 49280 (91%)

Texel Rate

The GeForce 8800 Ultra should be quite a bit (more or less 123%) faster with regards to AF than the GeForce GT 340. (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 21568 (123%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 8800 Ultra is the winner, and very much so. (explain)

GeForce 8800 Ultra		14688 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 10288 (234%)

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 largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 ability to get to the max fill rate.
