GeForce GTX 1660 Ti vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which comes with clock speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 memory. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1660 Ti is 40% faster than the Radeon RX 470 in general, because of its higher data rate. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
Radeon RX 470		211200 MB/sec
	Difference: 83712 (40%)

Texel Rate

The GeForce GTX 1660 Ti will be a lot (about 21%) more effective at texture filtering than the Radeon RX 470. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 25472 (21%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1660 Ti is the winner, and very much so. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 42368 (143%)

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 (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
