GeForce GT 440 3GB vs GeForce GTX 560 Ti

Intro

Compare those specifications to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has clocked the core speed at 822 MHz. The GDDR5 memory is set to run at a speed of 1002 MHz on this specific model. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 440 3GB		56 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 114 Watts (204%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 560 Ti should in theory be much superior to the GeForce GT 440 3GB overall. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 85056 (197%)

Texel Rate

The GeForce GTX 560 Ti should be quite a bit (approximately 269%) more effective at AF than the GeForce GT 440 3GB. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 38352 (269%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti is a better choice, and very much so. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 12048 (85%)

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 transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per 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 graphics 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 video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
