GeForce GT 230 vs GeForce GT 440 3GB

Intro

Compare all of that to the GeForce GT 440 3GB, which features GPU clock speed of 594 MHz, and 3072 MB of GDDR3 memory set to run at 900 MHz through a 192-bit bus. It also is comprised of 144 Stream Processors, 24 TAUs, and 24 Raster Operation Units.

GeForce GT 230		8800 Mtexels/sec
	Difference: 5456 (62%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GT 440 3GB is a better choice, by far. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
GeForce GT 230		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 maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
