GeForce GT 130 vs Radeon HD 5830

Intro

Compare those specs to the Radeon HD 5830, which features core speeds of 800 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 1120(224x5) SPUs as well as 56 Texture Address Units 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

Theoretically, the Radeon HD 5830 should be quite a bit faster than the GeForce GT 130 overall. (explain)

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

Texel Rate

The Radeon HD 5830 should be a lot (approximately 273%) faster with regards to texture filtering than the GeForce GT 130. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 5830 is a better choice, 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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video 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 video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
