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

Intro

Compare those specs to the GeForce GT 340 1GB, which makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM runs at a speed of 850 MHz on this model. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

In theory, the GeForce 8800 GTS (G92) should be just a bit faster than 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) is quite a bit (approximately 136%) better 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

If using lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G92) is the winner, by far. (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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
