GeForce GT 230 vs Radeon HD 6750

Intro

Compare that to the Radeon HD 6750, which features a core clock frequency of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is comprised of 720 SPUs, 36 Texture Address Units, and 16 ROPs.

GeForce GT 230		8800 Mtexels/sec
	Difference: 17300 (197%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 6750 is the winner, and very much so. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce GT 230		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 largest amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per 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 number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
