GeForce GT 130 vs Radeon HD 5830

Intro

Compare those specs to the Radeon HD 5830, which uses a 40 nm design. AMD has clocked the core speed 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 GT 130		75 Watts
Radeon HD 5830		175 Watts
	Difference: 100 Watts (133%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 is 967% quicker than the GeForce GT 130 in general, because of its greater data rate. (explain)

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

Texel Rate

The Radeon HD 5830 should be much (about 273%) better 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

The Radeon HD 5830 should be quite a bit (more or less 60%) better at FSAA than the GeForce GT 130, and also will be capable of handling higher resolutions better. (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 maximum amount of information (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the 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 maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
