GeForce 830M vs GeForce GTX 1050 Ti

Intro

Compare those specifications to the GeForce GTX 1050 Ti, which has core clock speeds of 1290 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 768 SPUs as well as 48 Texture Address Units and 32 Rasterization Operator Units.

GeForce 830M		16464 Mtexels/sec
	Difference: 45456 (276%)

Pixel Rate

The GeForce GTX 1050 Ti is a lot (about 401%) more effective at anti-aliasing than the GeForce 830M, and will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 33048 (401%)

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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card 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 that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated 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 filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
