GeForce 920M vs GeForce GT 310

Intro

Compare all of that to the GeForce GT 310, which has GPU clock speed of 589 MHz, and 512 MB of DDR2 RAM set to run at 1000 MHz through a 64-bit bus. It also is comprised of 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 310 will be 11% faster than the GeForce 920M in general, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce 920M should be much (more or less 548%) faster with regards to AF 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 is quite a bit (about 224%) more effective at AA than the GeForce GT 310, and able to handle higher screen resolutions more effectively. (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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 are applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
