Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750 1GB		86 Watts
GeForce GTS 150		141 Watts
	Difference: 55 Watts (64%)

Memory Bandwidth

In theory, the Radeon HD 6750 1GB is 100% faster than the GeForce GTS 150 overall, due to its higher bandwidth. (explain)

Radeon HD 6750 1GB		64000 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 32000 (100%)

Texel Rate

The GeForce GTS 150 will be quite a bit (about 81%) faster with regards to AF than the Radeon HD 6750 1GB. (explain)

GeForce GTS 150		47360 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 21260 (81%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTS 150 is a better choice, though only just barely. (explain)

GeForce GTS 150		11840 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 240 (2%)

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 information (in units of MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, 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 maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
