GeForce GT 310 vs Radeon HD 6770

Intro

Compare all that to the Radeon HD 6770, which features core clock speeds of 900 MHz on the GPU, and 1050 MHz on the 512 MB of GDDR5 memory. It features 800 SPUs along with 40 Texture Address Units and 16 ROPs.

GeForce GT 310		31 Watts
Radeon HD 6770		108 Watts
	Difference: 77 Watts (248%)

Memory Bandwidth

Theoretically, the Radeon HD 6770 should be quite a bit faster than the GeForce GT 310 in general. (explain)

Radeon HD 6770		67200 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 51200 (320%)

Texel Rate

The Radeon HD 6770 will be much (more or less 664%) better at texture filtering than the GeForce GT 310. (explain)

Radeon HD 6770		36000 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 31288 (664%)

Pixel Rate

The Radeon HD 6770 will be much (about 511%) faster with regards to AA than the GeForce GT 310, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon HD 6770		14400 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 12044 (511%)

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 largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
