GeForce GTX 1660 Ti vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which has core clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Radeon RX 550		50 Watts
GeForce GTX 1660 Ti		120 Watts
	Difference: 70 Watts (140%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1660 Ti will be 157% faster than the Radeon RX 550 overall, due to its higher data rate. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 180224 (157%)

Texel Rate

The GeForce GTX 1660 Ti will be much (more or less 309%) better at texture filtering than the Radeon RX 550. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 108800 (309%)

Pixel Rate

The GeForce GTX 1660 Ti should be a lot (about 309%) more effective at FSAA than the Radeon RX 550, and capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 54400 (309%)

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 largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
