GeForce GT 440 1.5GB vs GeForce GTX 280

Intro

Compare all that to the GeForce GTX 280, which uses a 65 nm design. nVidia has clocked the core frequency at 602 MHz. The GDDR3 RAM runs at a frequency of 1107 MHz on this specific card. It features 240 SPUs as well as 80 TAUs and 32 ROPs.

Texel Rate

The GeForce GTX 280 is much (about 238%) more effective at texture filtering than the GeForce GT 440 1.5GB. (explain)

GeForce GTX 280		48160 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 33904 (238%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 280 is superior to the GeForce GT 440 1.5GB, by a large margin. (explain)

GeForce GTX 280		19264 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 5008 (35%)

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 max amount of data (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
