GeForce GTX 260 Core 216		111888 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 57488 (106%)

Texel Rate

The GeForce GTX 260 Core 216 should be quite a bit (approximately 136%) faster with regards to texture filtering than the GeForce GT 340 1GB. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 23872 (136%)

Pixel Rate

The GeForce GTX 260 Core 216 is much (approximately 267%) better at AA than the GeForce GT 340 1GB, and also should be capable of handling higher resolutions better. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 11728 (267%)

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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's 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 also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
