GeForce GTX 1660 Ti vs Radeon R9 290X

Intro

The GeForce GTX 1660 Ti features a core clock speed of 1500 MHz and a GDDR6 memory frequency of 12000 MHz. It also uses a 192-bit bus, and uses a 12 nm design. It is made up of 1536 SPUs, 96 Texture Address Units, and 48 Raster Operation Units.

Compare those specifications to the Radeon R9 290X, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this card. It features 2816 SPUs along with 176 TAUs and 64 ROPs.

GeForce GTX 1660 Ti 120 Watts
Radeon R9 290X 300 Watts
Difference: 180 Watts (150%)

Memory Bandwidth

Theoretically, the Radeon R9 290X should perform just a bit faster than the GeForce GTX 1660 Ti in general. (explain)

Radeon R9 290X 320000 MB/sec
GeForce GTX 1660 Ti 294912 MB/sec
Difference: 25088 (9%)

Texel Rate

The GeForce GTX 1660 Ti is a small bit (more or less 2%) more effective at texture filtering than the Radeon R9 290X. (explain)

GeForce GTX 1660 Ti 144000 Mtexels/sec
Radeon R9 290X 140800 Mtexels/sec
Difference: 3200 (2%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1660 Ti is a better choice, and very much so. (explain)

GeForce GTX 1660 Ti 72000 Mpixels/sec
Radeon R9 290X 51200 Mpixels/sec
Difference: 20800 (41%)

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 MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
