GeForce 825M vs GeForce GTX 950

Intro

Compare all that to the GeForce GTX 950, which comes with GPU clock speed of 1024 MHz, and 2048 MB of GDDR5 memory set to run at 1652 MHz through a 128-bit bus. It also is comprised of 768 Stream Processors, 48 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 825M		33 Watts
GeForce GTX 950		90 Watts
	Difference: 57 Watts (173%)

Memory Bandwidth

In theory, the GeForce GTX 950 is 634% faster than the GeForce 825M in general, because of its greater bandwidth. (explain)

GeForce GTX 950		105728 MB/sec
GeForce 825M		14400 MB/sec
	Difference: 91328 (634%)

Texel Rate

The GeForce GTX 950 should be a lot (more or less 261%) faster with regards to anisotropic filtering than the GeForce 825M. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce 825M		13600 Mtexels/sec
	Difference: 35552 (261%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 950 is superior to the GeForce 825M, and very much so. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce 825M		6800 Mpixels/sec
	Difference: 25968 (382%)

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 data (measured in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. 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 - the lower the bandwidth is, the lower the potential to get to the max fill rate.
