GeForce GT 440 3GB vs Radeon HD 5450

Intro

Compare those specs to the Radeon HD 5450, which makes use of a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 memory is set to run at a frequency of 800 MHz on this specific model. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5450		19 Watts
GeForce GT 440 3GB		56 Watts
	Difference: 37 Watts (195%)

Memory Bandwidth

The GeForce GT 440 3GB should theoretically perform quite a bit faster than the Radeon HD 5450 overall. (explain)

GeForce GT 440 3GB		43200 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 30400 (238%)

Texel Rate

The GeForce GT 440 3GB should be a lot (more or less 174%) more effective at AF than the Radeon HD 5450. (explain)

GeForce GT 440 3GB		14256 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 9056 (174%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 440 3GB is a better choice, and very much so. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 11656 (448%)

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 transported over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
