GeForce GTX 880M vs Radeon RX 5500

Intro

Compare all of that to the Radeon RX 5500, which has a clock speed of 1670 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and makes use of a 7 nm design. It is comprised of 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 should be 79% quicker than the GeForce GTX 880M overall, because of its higher bandwidth. (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 (more or less 20%) better at anisotropic filtering than the GeForce GTX 880M. (explain)

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

Pixel Rate

The Radeon RX 5500 is quite a bit (approximately 75%) more effective at AA than the GeForce GTX 880M, and also will be able to handle higher resolutions better. (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 data (in units of MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends 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 max fill rate.
