GeForce GT 130 vs Radeon HD 5450

Intro

Compare those specs to the Radeon HD 5450, which comes with core clock speeds of 650 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 RAM. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5450		19 Watts
GeForce GT 130		75 Watts
	Difference: 56 Watts (295%)

Memory Bandwidth

The Radeon HD 5450, in theory, should be a small bit faster than the GeForce GT 130 overall. (explain)

Radeon HD 5450		12800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 800 (7%)

Texel Rate

The GeForce GT 130 should be a lot (approximately 131%) better at anisotropic filtering than the Radeon HD 5450. (explain)

GeForce GT 130		12000 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 6800 (131%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 130 is the winner, and very much so. (explain)

GeForce GT 130		8000 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 5400 (208%)

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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 processed per second. This 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
