GeForce GT 220 GDDR3 vs GeForce GTX 950M

Intro

The GeForce GT 220 GDDR3 uses a 40 nm design. nVidia has clocked the core speed at 625 MHz. The GDDR3 memory is set to run at a speed of 1012 MHz on this model. It features 48 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare those specs to the GeForce GTX 950M, which has clock speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

GeForce GT 220 GDDR3 32384 MB/sec
GeForce GTX 950M 32000 MB/sec
Difference: 384 (1%)

Texel Rate

The GeForce GTX 950M is much (more or less 266%) better at texture filtering than the GeForce GT 220 GDDR3. (explain)

GeForce GTX 950M 36560 Mtexels/sec
GeForce GT 220 GDDR3 10000 Mtexels/sec
Difference: 26560 (266%)

Pixel Rate

The GeForce GTX 950M is quite a bit (about 192%) faster with regards to anti-aliasing than the GeForce GT 220 GDDR3, and also able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 950M 14624 Mpixels/sec
GeForce GT 220 GDDR3 5000 Mpixels/sec
Difference: 9624 (192%)

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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
