Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon HD 6450 (OEM) 1GB is 80% faster than the GeForce GT 310 overall, due to its greater bandwidth. (explain)

Radeon HD 6450 (OEM) 1GB		28800 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 12800 (80%)

Texel Rate

The Radeon HD 6450 (OEM) 1GB should be much (about 27%) faster with regards to AF than the GeForce GT 310. (explain)

Radeon HD 6450 (OEM) 1GB		6000 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 1288 (27%)

Pixel Rate

The Radeon HD 6450 (OEM) 1GB should be much (more or less 27%) faster with regards to anti-aliasing than the GeForce GT 310, and also will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon HD 6450 (OEM) 1GB		3000 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 644 (27%)

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 (in units of MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 can be processed per second. This is worked out by multiplying the total 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 a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 reach the maximum fill rate.
