GeForce GTX 560 Ti 448 vs Radeon HD 5830

Intro

Compare those specifications to the Radeon HD 5830, which comes with core clock speeds of 800 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1120(224x5) SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

The Radeon HD 5830 is just a bit (more or less 9%) more effective at AF than the GeForce GTX 560 Ti 448. (explain)

Radeon HD 5830		44800 Mtexels/sec
GeForce GTX 560 Ti 448		40992 Mtexels/sec
	Difference: 3808 (9%)

Pixel Rate

The GeForce GTX 560 Ti 448 should be quite a bit (approximately 129%) more effective at anti-aliasing than the Radeon HD 5830, and also able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 16480 (129%)

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 data (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics 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 clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
