GeForce GTX 560 Ti vs Radeon HD 5830

Intro

Compare all of that to the Radeon HD 5830, which comes with core speeds of 800 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1120(224x5) SPUs as well as 56 TAUs 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

In theory, the GeForce GTX 560 Ti should be 0% quicker than the Radeon HD 5830 in general, due to its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 560 Ti should be a bit (about 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

The GeForce GTX 560 Ti will be a lot (more or less 106%) faster with regards to anti-aliasing than the Radeon HD 5830, and will be able to handle higher screen resolutions without slowing down too much. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
