GeForce GTX 1660 Ti vs Radeon R9 285

Intro

The GeForce GTX 1660 Ti comes with a GPU core speed of 1500 MHz, and the 6144 MB of GDDR6 memory is set to run at 1500 MHz through a 192-bit bus. It also is made up of 1536 Stream Processors, 96 Texture Address Units, and 48 ROPs.

Compare those specs to the Radeon R9 285, which features a clock speed of 918 MHz and a GDDR5 memory speed of 1375 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Theoretically speaking, the GeForce GTX 1660 Ti is 68% faster than the Radeon R9 285 in general, due to its higher bandwidth. (explain)

GeForce GTX 1660 Ti 294912 MB/sec
Radeon R9 285 176000 MB/sec
Difference: 118912 (68%)

Texel Rate

The GeForce GTX 1660 Ti should be quite a bit (more or less 40%) faster with regards to anisotropic filtering than the Radeon R9 285. (explain)

GeForce GTX 1660 Ti 144000 Mtexels/sec
Radeon R9 285 102816 Mtexels/sec
Difference: 41184 (40%)

Pixel Rate

If using high levels of AA 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 R9 285 29376 Mpixels/sec
Difference: 42624 (145%)

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 (measured in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
