GeForce GT 240 GDDR5 vs Radeon HD 6750

Intro

Compare those specs to the Radeon HD 6750, which has core speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 720 SPUs as well as 36 TAUs and 16 ROPs.

GeForce GT 240 GDDR5		70 Watts
Radeon HD 6750		86 Watts
	Difference: 16 Watts (23%)

Memory Bandwidth

In theory, the Radeon HD 6750 will be 18% faster than the GeForce GT 240 GDDR5 overall, because of its higher bandwidth. (explain)

Radeon HD 6750		64000 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The Radeon HD 6750 is quite a bit (more or less 48%) better 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 is a lot (approximately 164%) more effective at FSAA than the GeForce GT 240 GDDR5, and capable of handling higher resolutions better. (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: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 can be processed in one second. This is calculated by multiplying the total texture units of the card by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out 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 filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
