GeForce GTX 1660 Ti vs Radeon RX 470 4GB

Intro

Compare those specifications to the Radeon RX 470 4GB, which makes use of a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 memory is set to run at a frequency of 1650 MHz on this specific model. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 1660 Ti should theoretically be much faster than the Radeon RX 470 4GB overall. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 83712 (40%)

Texel Rate

The GeForce GTX 1660 Ti is much (approximately 21%) more effective at AF than the Radeon RX 470 4GB. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 25472 (21%)

Pixel Rate

The GeForce GTX 1660 Ti should be quite a bit (about 143%) faster with regards to FSAA than the Radeon RX 470 4GB, and will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon RX 470 4GB		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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
