GeForce GTX 1650 vs GeForce GTX 880M

Intro

Compare those specifications to the GeForce GTX 880M, which comes with core speeds of 954 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1536 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
GeForce GTX 880M		130 Watts
	Difference: 55 Watts (73%)

Memory Bandwidth

In theory, the GeForce GTX 1650 is 2% quicker than the GeForce GTX 880M in general, because of its greater data rate. (explain)

GeForce GTX 1650		131072 MB/sec
GeForce GTX 880M		128000 MB/sec
	Difference: 3072 (2%)

Texel Rate

The GeForce GTX 880M will be quite a bit (approximately 47%) more effective at texture filtering than the GeForce GTX 1650. (explain)

GeForce GTX 880M		122112 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 38952 (47%)

Pixel Rate

The GeForce GTX 1650 will be much (more or less 56%) better at AA than the GeForce GTX 880M, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 880M		30528 Mpixels/sec
	Difference: 16992 (56%)

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 (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated 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 rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
