GeForce GT 310 vs GeForce GTX 880M

Intro

Compare those specifications to the GeForce GTX 880M, which features GPU core speed of 954 MHz, and 4096 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also features 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310		31 Watts
GeForce GTX 880M		130 Watts
	Difference: 99 Watts (319%)

Memory Bandwidth

The GeForce GTX 880M should theoretically be quite a bit faster than the GeForce GT 310 in general. (explain)

GeForce GTX 880M		128000 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 112000 (700%)

Texel Rate

The GeForce GTX 880M will be much (more or less 2492%) more effective at anisotropic filtering than the GeForce GT 310. (explain)

GeForce GTX 880M		122112 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 117400 (2492%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 880M is a better choice, and very much so. (explain)

GeForce GTX 880M		30528 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 28172 (1196%)

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 (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record 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 core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
