GeForce 920M vs GeForce GT 310

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 310 should perform a bit faster than the GeForce 920M overall. (explain)

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

Texel Rate

The GeForce 920M should be a lot (more or less 548%) more effective at texture filtering than the GeForce GT 310. (explain)

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

Pixel Rate

The GeForce 920M will be quite a bit (about 224%) better at anti-aliasing than the GeForce GT 310, and also should be able to handle higher screen resolutions while still performing well. (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 maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
