GeForce GTX 465 vs Radeon HD 6750 1GB

Intro

Compare those specifications to the Radeon HD 6750 1GB, which uses a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular model. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.

Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 608 (2%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 465 is a better choice, and very much so. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 7824 (67%)

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 data (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 ability to get to the maximum fill rate.
