GeForce GT 220 GDDR3 vs GeForce GTX 950M

Intro

Compare all that 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 along with 40 Texture Address Units and 16 ROPs.

The GeForce GTX 950M should be a lot (more or less 266%) faster with regards to 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 a lot (approximately 192%) better at AA than the GeForce GT 220 GDDR3, and also should be able to handle higher screen resolutions while still performing well. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
