GeForce GTX 1660 Ti vs Radeon RX 480

Intro

The GeForce GTX 1660 Ti has a clock frequency of 1500 MHz and a GDDR6 memory frequency of 1500 MHz. It also makes use of a 192-bit bus, and makes use of a 12 nm design. It is comprised of 1536 SPUs, 96 Texture Address Units, and 48 Raster Operation Units.

Compare all that to the Radeon RX 480, which uses a 14 nm design. AMD has set the core frequency at 1120 MHz. The GDDR5 memory works at a speed of 2000 MHz on this particular model. It features 2304 SPUs along with 144 Texture Address Units and 32 Rasterization Operator Units.

The Radeon RX 480 will be just a bit (more or less 12%) more effective at texture 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

The GeForce GTX 1660 Ti will be much (more or less 101%) faster with regards to anti-aliasing than the Radeon RX 480, and will be able to handle higher resolutions more effectively. (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.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
