GeForce GTX 880M vs GeForce RTX 2080 SUPER

Intro

Compare all that to the GeForce RTX 2080 SUPER, which comes with clock speeds of 1650 MHz on the GPU, and 1937 MHz on the 8192 MB of GDDR6 memory. It features 3072 SPUs along with 192 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 880M		130 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 120 Watts (92%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER is 297% quicker than the GeForce GTX 880M overall, because of its higher bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GTX 880M		128000 MB/sec
	Difference: 379904 (297%)

Texel Rate

The GeForce RTX 2080 SUPER should be much (approximately 159%) better at anisotropic filtering than the GeForce GTX 880M. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 880M		122112 Mtexels/sec
	Difference: 194688 (159%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is superior to the GeForce GTX 880M, and very much so. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 880M		30528 Mpixels/sec
	Difference: 75072 (246%)

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 (in units of megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
