GeForce GT 440 3GB vs GeForce GTX 260 216SP 55 nm

Intro

Compare all of that to the GeForce GTX 260 216SP 55 nm, which has GPU clock speed of 576 MHz, and 896 MB of GDDR3 memory running at 999 MHz through a 448-bit bus. It also is made up of 216 Stream Processors, 72 TAUs, and 28 ROPs.

	Difference: 68688 (159%)

Texel Rate

The GeForce GTX 260 216SP 55 nm should be quite a bit (more or less 191%) more effective at AF than the GeForce GT 440 3GB. (explain)

GeForce GTX 260 216SP 55 nm		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 216SP 55 nm is a better choice, but not by far. (explain)

GeForce GTX 260 216SP 55 nm		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: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its 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 card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
