GeForce 9800 GT 1GB vs GeForce GT 340 1GB

Intro

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

GeForce 9800 GT 1GB		33600 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 16000 (91%)

Pixel Rate

The GeForce 9800 GT 1GB should be quite a bit (more or less 118%) more effective at FSAA than the GeForce GT 340 1GB, and also should be able to handle higher resolutions better. (explain)

GeForce 9800 GT 1GB		9600 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 5200 (118%)

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 data (measured in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
