GeForce GT 340 vs GeForce GT 440 3GB

Intro

Compare those specs to the GeForce GT 440 3GB, which has GPU clock speed of 594 MHz, and 3072 MB of GDDR3 RAM running at 900 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 Texture Address Units, and 24 Raster Operation Units.

GeForce GT 440 3GB		43200 MB/sec
	Difference: 11200 (26%)

Texel Rate

The GeForce GT 340 will be quite a bit (about 23%) better at AF than the GeForce GT 440 3GB. (explain)

GeForce GT 340		17600 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 3344 (23%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 440 3GB is superior to the GeForce GT 340, and very much so. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
GeForce GT 340		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 past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 amount of texture units of the card by the core clock 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 maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
