GeForce GT 210 vs GeForce GT 440 1.5GB

Intro

Compare all that to the GeForce GT 440 1.5GB, which comes with a clock frequency of 594 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It is made up of 144 SPUs, 24 Texture Address Units, and 24 ROPs.

	Difference: 30400 (238%)

Texel Rate

The GeForce GT 440 1.5GB is quite a bit (more or less 203%) better at texture filtering than the GeForce GT 210. (explain)

GeForce GT 440 1.5GB		14256 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 9544 (203%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 440 1.5GB is a better choice, by a large margin. (explain)

GeForce GT 440 1.5GB		14256 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 11900 (505%)

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 largest amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
