GeForce GT 315 vs Radeon HD 6750 1GB

Intro

Compare all of that to the Radeon HD 6750 1GB, which uses a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this card. It features 720 SPUs along with 36 TAUs and 16 ROPs.

GeForce GT 315		25280 MB/sec
	Difference: 38720 (153%)

Texel Rate

The Radeon HD 6750 1GB should be much (more or less 161%) better at AF than the GeForce GT 315. (explain)

Radeon HD 6750 1GB		26100 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 16100 (161%)

Pixel Rate

The Radeon HD 6750 1GB should be quite a bit (approximately 132%) better at anti-aliasing than the GeForce GT 315, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 6600 (132%)

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 information (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
