GeForce 825M vs GeForce GTX 1050 Ti

Intro

Compare all of that to the GeForce GTX 1050 Ti, which comes with a GPU core clock speed of 1290 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 768 Stream Processors, 48 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 825M		33 Watts
GeForce GTX 1050 Ti		75 Watts
	Difference: 42 Watts (127%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 Ti should be a lot faster than the GeForce 825M overall. (explain)

GeForce GTX 1050 Ti		114688 MB/sec
GeForce 825M		14400 MB/sec
	Difference: 100288 (696%)

Texel Rate

The GeForce GTX 1050 Ti should be much (approximately 355%) faster with regards to texture filtering than the GeForce 825M. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
GeForce 825M		13600 Mtexels/sec
	Difference: 48320 (355%)

Pixel Rate

The GeForce GTX 1050 Ti should be quite a bit (about 507%) more effective at FSAA than the GeForce 825M, and also will be able to handle higher screen resolutions better. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
GeForce 825M		6800 Mpixels/sec
	Difference: 34480 (507%)

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 maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
