GeForce GT 440 3GB vs GeForce GTX 260 Core 216

Intro

Compare that to the GeForce GTX 260 Core 216, which features a clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also makes use of a 448-bit memory bus, and makes use of a 65 nm design. It is comprised of 216 SPUs, 72 Texture Address Units, and 28 ROPs.

GeForce GTX 260 Core 216		202 Watts
	Difference: 146 Watts (261%)

Memory Bandwidth

In theory, the GeForce GTX 260 Core 216 should be quite a bit faster than the GeForce GT 440 3GB in general. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 68688 (159%)

Texel Rate

The GeForce GTX 260 Core 216 will be quite a bit (more or less 191%) more effective at texture filtering than the GeForce GT 440 3GB. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 27216 (191%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 260 Core 216 is superior to the GeForce GT 440 3GB, but it probably won't make a huge difference. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 1872 (13%)

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 MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
