GeForce 825M vs GeForce GTX 1650

Intro

Compare those specifications to the GeForce GTX 1650, which has a core clock frequency of 1485 MHz and a GDDR5 memory speed of 2001 MHz. It also makes use of a 128-bit memory bus, and makes use of a 12 nm design. It is made up of 896 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 825M		33 Watts
GeForce GTX 1650		75 Watts
	Difference: 42 Watts (127%)

Memory Bandwidth

In theory, the GeForce GTX 1650 should be 810% quicker than the GeForce 825M overall, due to its greater data rate. (explain)

GeForce GTX 1650		131072 MB/sec
GeForce 825M		14400 MB/sec
	Difference: 116672 (810%)

Texel Rate

The GeForce GTX 1650 should be quite a bit (more or less 511%) more effective at texture filtering than the GeForce 825M. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce 825M		13600 Mtexels/sec
	Difference: 69560 (511%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1650 is superior to the GeForce 825M, by far. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce 825M		6800 Mpixels/sec
	Difference: 40720 (599%)

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 max amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 are applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
