The GeForce GTX 285 1GB is quite a bit (about 195%) more effective at texture filtering than the GeForce GT 340. (explain)

GeForce GTX 285 1GB		51840 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 34240 (195%)

Pixel Rate

The GeForce GTX 285 1GB will be a lot (more or less 371%) better at anti-aliasing than the GeForce GT 340, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 285 1GB		20736 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 16336 (371%)

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. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
