GeForce GTX 560 Ti vs Radeon HD 5830

Intro

Compare those specs to the Radeon HD 5830, which makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this specific card. It features 1120(224x5) SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 Ti		170 Watts
Radeon HD 5830		175 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

Theoretically, the GeForce GTX 560 Ti should perform just a bit faster than the Radeon HD 5830 overall. (explain)

GeForce GTX 560 Ti		128256 MB/sec
Radeon HD 5830		128000 MB/sec
	Difference: 256 (0%)

Texel Rate

The GeForce GTX 560 Ti is a little bit (more or less 17%) more effective at AF than the Radeon HD 5830. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 7808 (17%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 560 Ti is the winner, by far. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 13504 (106%)

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 (in units of MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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 colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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.
