GeForce GTX 550 Ti vs Radeon HD 6750 1GB

Intro

Compare all of that to the Radeon HD 6750 1GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this model. It features 720 SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Texel Rate

The GeForce GTX 550 Ti should be a small bit (about 10%) faster with regards to anisotropic filtering than the Radeon HD 6750 1GB. (explain)

GeForce GTX 550 Ti		28800 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 2700 (10%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 550 Ti is superior to the Radeon HD 6750 1GB, and very much so. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 10000 (86%)

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 (measured in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
