GeForce GT 220 GDDR3 vs GeForce GTX 950M

Intro

The GeForce GT 220 GDDR3 comes with a GPU core speed of 625 MHz, and the 512 MB of GDDR3 RAM is set to run at 1012 MHz through a 128-bit bus. It also features 48 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the GeForce GTX 950M, which features 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 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M 55 Watts
GeForce GT 220 GDDR3 58 Watts
Difference: 3 Watts (5%)

Memory Bandwidth

Theoretically, the GeForce GT 220 GDDR3 should be just a bit faster than the GeForce GTX 950M in general. (explain)

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

Texel Rate

The GeForce GTX 950M is quite a bit (about 266%) faster with regards to AF 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

If running with a high resolution is important to you, then the GeForce GTX 950M is a better choice, and very much so. (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 max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
