GeForce GT 440 3GB vs GeForce GTX 960M

Intro

Compare those specs to the GeForce GTX 960M, which uses a 28 nm design. nVidia has clocked the core frequency at 1096 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 440 3GB		56 Watts
GeForce GTX 960M		65 Watts
	Difference: 9 Watts (16%)

Memory Bandwidth

In theory, the GeForce GTX 960M will be 48% faster than the GeForce GT 440 3GB in general, because of its higher data rate. (explain)

GeForce GTX 960M		64000 MB/sec
GeForce GT 440 3GB		43200 MB/sec
	Difference: 20800 (48%)

Texel Rate

The GeForce GTX 960M will be quite a bit (about 208%) better at AF than the GeForce GT 440 3GB. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 29584 (208%)

Pixel Rate

The GeForce GTX 960M is quite a bit (more or less 23%) more effective at AA than the GeForce GT 440 3GB, and also should be capable of handling higher resolutions better. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 3280 (23%)

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 maximum amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
