GeForce GT 310 vs GeForce GTX 950M

Intro

The GeForce GT 310 features a GPU clock speed of 589 MHz, and the 512 MB of DDR2 RAM is set to run at 1000 MHz through a 64-bit bus. It also is comprised of 16 SPUs, 8 Texture Address Units, and 4 ROPs.

Compare that to the GeForce GTX 950M, which makes use of a 28 nm design. nVidia has clocked the core speed at 914 MHz. The DDR3 RAM works at a speed of 1000 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

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

Pixel Rate

The GeForce GTX 950M should be a lot (approximately 521%) faster with regards to AA than the GeForce GT 310, and should be able to handle higher screen resolutions without slowing down too much. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could 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 colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
