GeForce GTX 880M vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which comes with core clock speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 RAM. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

	Difference: 53888 (44%)

Pixel Rate

The Radeon RX 5600 is a lot (about 188%) better at AA than the GeForce GTX 880M, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 5600		88000 Mpixels/sec
GeForce GTX 880M		30528 Mpixels/sec
	Difference: 57472 (188%)

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 (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
