GeForce 940M vs GeForce GT 320

Intro

Compare those specs to the GeForce GT 320, which makes use of a 40 nm design. nVidia has clocked the core speed at 540 MHz. The GDDR3 memory works at a speed of 790 MHz on this specific card. It features 72 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 320 will be 58% faster than the GeForce 940M in general, due to its higher data rate. (explain)

GeForce GT 320		25280 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 9280 (58%)

Texel Rate

The GeForce 940M should be a lot (approximately 99%) faster with regards to AF than the GeForce GT 320. (explain)

GeForce 940M		25728 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 12768 (99%)

Pixel Rate

The GeForce 940M will be a lot (about 99%) more effective at FSAA than the GeForce GT 320, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 940M		8576 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 4256 (99%)

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 largest amount of data (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
