GeForce 8800 GTS (G92) vs GeForce GT 340

Intro

Compare those specs to the GeForce GT 340, which has a core clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is comprised of 96 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.

	Difference: 7680 (14%)

Texel Rate

The GeForce 8800 GTS (G92) is quite a bit (approximately 136%) more effective at texture filtering than the GeForce GT 340. (explain)

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

Pixel Rate

The GeForce 8800 GTS (G92) will be quite a bit (more or less 136%) better at anti-aliasing than the GeForce GT 340, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce 8800 GTS (G92)		10400 Mpixels/sec
GeForce GT 340		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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
