GeForce GT 440 3GB vs Radeon HD 5550

Intro

Compare those specs to the Radeon HD 5550, which has GPU clock speed of 550 MHz, and 512 MB of DDR2 RAM running at 400 MHz through a 128-bit bus. It also is made up of 320(64x5) Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 440 3GB should perform a lot faster than the Radeon HD 5550 overall. (explain)

GeForce GT 440 3GB		43200 MB/sec
Radeon HD 5550		12800 MB/sec
	Difference: 30400 (238%)

Texel Rate

The GeForce GT 440 3GB will be quite a bit (approximately 62%) more effective at anisotropic filtering than the Radeon HD 5550. (explain)

GeForce GT 440 3GB		14256 Mtexels/sec
Radeon HD 5550		8800 Mtexels/sec
	Difference: 5456 (62%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 440 3GB is superior to the Radeon HD 5550, by a large margin. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
Radeon HD 5550		4400 Mpixels/sec
	Difference: 9856 (224%)

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 information (in units of MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
