GeForce GT 130 vs Radeon HD 5450

Intro

Compare that to the Radeon HD 5450, which comes with a GPU core clock speed of 650 MHz, and 512 MB of DDR3 memory running at 800 MHz through a 64-bit bus. It also is comprised of 80(16x5) Stream Processors, 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 should theoretically be a little 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 is a lot (approximately 131%) better at texture 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 high levels of AA is important to you, then the GeForce GT 130 is superior to the Radeon HD 5450, 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 (counted in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 potential to get to the max fill rate.
