GeForce GTX 880M vs Radeon RX 6500 XT

Intro

Compare those specifications to the Radeon RX 6500 XT, which has GPU core speed of 2200 MHz, and 4096 MB of GDDR6 memory set to run at 2250 MHz through a 64-bit bus. It also is made up of 1024 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 880M		130 Watts
	Difference: 23 Watts (21%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6500 XT should in theory be a bit better than the GeForce GTX 880M overall. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 880M		128000 MB/sec
	Difference: 19456 (15%)

Texel Rate

The Radeon RX 6500 XT is a small bit (more or less 15%) faster with regards to AF than the GeForce GTX 880M. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 880M		122112 Mtexels/sec
	Difference: 18688 (15%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6500 XT is superior to the GeForce GTX 880M, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 880M		30528 Mpixels/sec
	Difference: 39872 (131%)

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 maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
