GeForce GTX 980 Ti vs Radeon RX 5500

Intro

Compare those specs to the Radeon RX 5500, which has core speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 RAM. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

Radeon RX 5500		150 Watts
GeForce GTX 980 Ti		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

In theory, the GeForce GTX 980 Ti should be quite a bit faster than the Radeon RX 5500 in general. (explain)

GeForce GTX 980 Ti		336000 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 106624 (46%)

Texel Rate

The GeForce GTX 980 Ti should be a bit (more or less 20%) better at anisotropic filtering than the Radeon RX 5500. (explain)

GeForce GTX 980 Ti		176000 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 29040 (20%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 980 Ti is superior to the Radeon RX 5500, by far. (explain)

GeForce GTX 980 Ti		96000 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 42560 (80%)

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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
