GeForce 920M vs GeForce GT 310

Intro

Compare those specs to the GeForce GT 310, which makes use of a 40 nm design. nVidia has set the core frequency at 589 MHz. The DDR2 memory is set to run at a speed of 1000 MHz on this particular card. It features 16 SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 310 is 11% quicker than the GeForce 920M in general, due to its greater data rate. (explain)

GeForce GT 310		16000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 920M is quite a bit (more or less 548%) faster with regards to texture filtering than the GeForce GT 310. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 25816 (548%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 920M is superior to the GeForce GT 310, by a large margin. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 5276 (224%)

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 (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of 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 most pixels that the graphics chip 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 number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 max fill rate.
