GeForce 825M vs Nvidia Titan Xp

Intro

Compare those specifications to the Nvidia Titan Xp, which has core speeds of 1582 MHz on the GPU, and 1426 MHz on the 12288 MB of GDDR5X RAM. It features 3840 SPUs along with 240 TAUs and 96 ROPs.

GeForce 825M		13600 Mtexels/sec
	Difference: 366080 (2692%)

Pixel Rate

The Nvidia Titan Xp is much (more or less 2133%) better at FSAA than the GeForce 825M, and also able to handle higher screen resolutions without losing too much performance. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
GeForce 825M		6800 Mpixels/sec
	Difference: 145072 (2133%)

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 the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
