GeForce GT 130 vs Radeon HD 5830

Intro

Compare that to the Radeon HD 5830, which features GPU core 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 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
Radeon HD 5830		175 Watts
	Difference: 100 Watts (133%)

Memory Bandwidth

In theory, the Radeon HD 5830 should perform much faster than the GeForce GT 130 in general. (explain)

Radeon HD 5830		128000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 116000 (967%)

Texel Rate

The Radeon HD 5830 should be quite a bit (more or less 273%) more effective at AF than the GeForce GT 130. (explain)

Radeon HD 5830		44800 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 32800 (273%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 5830 is the winner, and very much so. (explain)

Radeon HD 5830		12800 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 4800 (60%)

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 max amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also 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 bandwidth is, the lower the ability to reach the max fill rate.
