GeForce GTX Titan vs Radeon HD 5830

Intro

Compare all of that to the Radeon HD 5830, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific model. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Radeon HD 5830		175 Watts
GeForce GTX Titan		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

Theoretically, the GeForce GTX Titan should be much faster than the Radeon HD 5830 in general. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon HD 5830		128000 MB/sec
	Difference: 160384 (125%)

Texel Rate

The GeForce GTX Titan should be quite a bit (more or less 319%) better at AF than the Radeon HD 5830. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 142688 (319%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX Titan is the winner, by far. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 27376 (214%)

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 information (counted in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of 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 colour ROPs by the the core 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
