GeForce GT 230 vs Radeon HD 6750 1GB

Intro

Compare that to the Radeon HD 6750 1GB, which has GPU clock speed of 725 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 720 SPUs, 36 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
Radeon HD 6750 1GB		86 Watts
	Difference: 21 Watts (32%)

Memory Bandwidth

In theory, the Radeon HD 6750 1GB should be 67% quicker than the GeForce GT 230 overall, because of its greater data rate. (explain)

Radeon HD 6750 1GB		64000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The Radeon HD 6750 1GB will be much (approximately 197%) better at AF than the GeForce GT 230. (explain)

Radeon HD 6750 1GB		26100 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 17300 (197%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6750 1GB is a better choice, and very much so. (explain)

Radeon HD 6750 1GB		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: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
