Nvidia Titan X vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which features clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 512 SPUs along with 32 TAUs 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 a lot better than 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 is a lot (approximately 802%) more effective at texture filtering than the Radeon RX 550. (explain)

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

Pixel Rate

The Nvidia Titan X will be quite a bit (more or less 673%) more effective at FSAA than the Radeon RX 550, and also should be able to handle higher resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
