Nvidia Titan X vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which has GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
Nvidia Titan X		250 Watts
	Difference: 200 Watts (400%)

Memory Bandwidth

As far as performance goes, the Nvidia Titan X should theoretically be much superior to the Radeon RX 550 in general. (explain)

Nvidia Titan X		491520 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 376832 (329%)

Texel Rate

The Nvidia Titan X will be much (approximately 802%) more effective at anisotropic filtering than the Radeon RX 550. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 282208 (802%)

Pixel Rate

If running with high levels of AA is important to you, then the Nvidia Titan X is a better choice, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 118432 (673%)

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 (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
