GeForce GTX 1660 Ti vs Radeon RX 480

Intro

Compare all that to the Radeon RX 480, which comes with core speeds of 1120 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
Radeon RX 480		150 Watts
	Difference: 30 Watts (25%)

Memory Bandwidth

In theory, the GeForce GTX 1660 Ti will be 13% quicker than the Radeon RX 480 in general, due to its higher bandwidth. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
Radeon RX 480		262144 MB/sec
	Difference: 32768 (13%)

Texel Rate

The Radeon RX 480 should be a little bit (more or less 12%) more effective at anisotropic filtering than the GeForce GTX 1660 Ti. (explain)

Radeon RX 480		161280 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 17280 (12%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1660 Ti is the winner, by a large margin. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 36160 (101%)

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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the 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 core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
