GeForce GTX 880M vs Radeon RX 5500

Intro

Compare all that to the Radeon RX 5500, which has clock speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 RAM. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

GeForce GTX 880M		130 Watts
Radeon RX 5500		150 Watts
	Difference: 20 Watts (15%)

Memory Bandwidth

As far as performance goes, the Radeon RX 5500 should theoretically be much better than the GeForce GTX 880M overall. (explain)

Radeon RX 5500		229376 MB/sec
GeForce GTX 880M		128000 MB/sec
	Difference: 101376 (79%)

Texel Rate

The Radeon RX 5500 should be a bit (about 20%) better at AF than the GeForce GTX 880M. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce GTX 880M		122112 Mtexels/sec
	Difference: 24848 (20%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 5500 is the winner, and very much so. (explain)

Radeon RX 5500		53440 Mpixels/sec
GeForce GTX 880M		30528 Mpixels/sec
	Difference: 22912 (75%)

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 MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics 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 most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
