GeForce GT 340 1GB		54400 MB/sec
	Difference: 124800 (229%)

Texel Rate

The Radeon R9 270 is a lot (approximately 309%) more effective at anisotropic filtering than the GeForce GT 340 1GB. (explain)

Radeon R9 270		72000 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 54400 (309%)

Pixel Rate

The Radeon R9 270 should be quite a bit (approximately 555%) better at FSAA than the GeForce GT 340 1GB, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 270		28800 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 24400 (555%)

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 (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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