GeForce GTX 1660 Ti vs Radeon RX 480

Intro

The GeForce GTX 1660 Ti makes use of a 12 nm design. nVidia has set the core frequency at 1500 MHz. The GDDR6 RAM works at a frequency of 12000 MHz on this specific model. It features 1536 SPUs as well as 96 TAUs and 48 ROPs.

Compare those specifications to the Radeon RX 480, which features GPU clock speed of 1120 MHz, and 8192 MB of GDDR5 RAM running at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

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 (approximately 12%) faster with regards to AF 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 a better choice, 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
