GeForce GT 220 GDDR3 vs GeForce GTX 1050

Intro

Compare all of that to the GeForce GTX 1050, which comes with core clock speeds of 1354 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 1050		54160 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 44160 (442%)

Pixel Rate

The GeForce GTX 1050 will be a lot (more or less 767%) better at full screen anti-aliasing than the GeForce GT 220 GDDR3, and also will be able to handle higher resolutions more effectively. (explain)

GeForce GTX 1050		43328 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 38328 (767%)

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 (measured in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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.
