GeForce GT 310 vs GeForce GTX 950M

Intro

Compare all that to the GeForce GTX 950M, which features a GPU core clock speed of 914 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

GeForce GT 310		16000 MB/sec
	Difference: 16000 (100%)

Texel Rate

The GeForce GTX 950M will be much (approximately 676%) more effective at AF than the GeForce GT 310. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 31848 (676%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 950M is superior to the GeForce GT 310, and very much so. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 12268 (521%)

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 information (counted in MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
