GeForce GT 230 vs Radeon HD 6770

Intro

Compare those specs to the Radeon HD 6770, which has core clock speeds of 900 MHz on the GPU, and 1050 MHz on the 512 MB of GDDR5 RAM. It features 800 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

GeForce GT 230		38400 MB/sec
	Difference: 28800 (75%)

Texel Rate

The Radeon HD 6770 is quite a bit (more or less 309%) faster with regards to anisotropic filtering than the GeForce GT 230. (explain)

Radeon HD 6770		36000 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 27200 (309%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 6770 is superior to the GeForce GT 230, by far. (explain)

Radeon HD 6770		14400 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 10000 (227%)

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 maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
