Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310		31 Watts
GeForce GT 340 1GB		69 Watts
	Difference: 38 Watts (123%)

Memory Bandwidth

The GeForce GT 340 1GB should theoretically perform quite a bit faster than the GeForce GT 310 in general. (explain)

GeForce GT 340 1GB		54400 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 38400 (240%)

Texel Rate

The GeForce GT 340 1GB should be a lot (about 274%) better at AF than the GeForce GT 310. (explain)

GeForce GT 340 1GB		17600 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 12888 (274%)

Pixel Rate

The GeForce GT 340 1GB should be much (more or less 87%) faster with regards to full screen anti-aliasing than the GeForce GT 310, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GT 340 1GB		4400 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 2044 (87%)

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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
