GeForce GTX Titan X vs Radeon RX 5500

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
GeForce GTX Titan X		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan X should be 46% quicker than the Radeon RX 5500 in general, because of its greater data rate. (explain)

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

Texel Rate

The GeForce GTX Titan X is quite a bit (about 31%) better at anisotropic filtering than the Radeon RX 5500. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 45040 (31%)

Pixel Rate

The GeForce GTX Titan X should be a lot (about 80%) more effective at FSAA than the Radeon RX 5500, and also should be able to handle higher resolutions more effectively. (explain)

GeForce GTX Titan X		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 max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
