GeForce GT 240 GDDR5 vs Radeon HD 6750

Intro

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

The Radeon HD 6750 is much (approximately 48%) more effective at texture filtering than the GeForce GT 240 GDDR5. (explain)

Radeon HD 6750		26100 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 8500 (48%)

Pixel Rate

The Radeon HD 6750 will be a lot (about 164%) better at AA than the GeForce GT 240 GDDR5, and will be capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 7200 (164%)

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 (counted in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
