Nvidia Titan X vs Radeon HD 5830

Intro

Compare all that to the Radeon HD 5830, which features a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also is comprised of 1120(224x5) SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5830		175 Watts
Nvidia Titan X		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

Theoretically, the Nvidia Titan X should perform quite a bit faster than the Radeon HD 5830 in general. (explain)

Nvidia Titan X		491520 MB/sec
Radeon HD 5830		128000 MB/sec
	Difference: 363520 (284%)

Texel Rate

The Nvidia Titan X should be quite a bit (more or less 609%) more effective at anisotropic filtering than the Radeon HD 5830. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 272608 (609%)

Pixel Rate

If using a high resolution is important to you, then the Nvidia Titan X is the winner, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 123232 (963%)

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 transported past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 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.
