GeForce GTX 880M vs Radeon RX 5500

Intro

Compare all of that to the Radeon RX 5500, which makes use of a 7 nm design. AMD has set the core frequency at 1670 MHz. The GDDR6 memory runs at a speed of 1750 MHz on this particular model. It features 1408 SPUs as well as 88 Texture Address Units and 32 Rasterization Operator 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

In theory, the Radeon RX 5500 is 79% quicker than the GeForce GTX 880M overall, due to its higher data rate. (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 little bit (about 20%) faster with regards to 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 a lot (more or less 75%) more effective at FSAA than the GeForce GTX 880M, and should be capable of handling higher screen resolutions while still performing well. (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 max amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card 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 maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
