GeForce GTX 1660 Ti vs Radeon VII

Intro

The GeForce GTX 1660 Ti comes with clock speeds of 1500 MHz on the GPU, and 12000 MHz on the 6144 MB of GDDR6 RAM. It features 1536 SPUs as well as 96 TAUs and 48 ROPs.

Compare all of that to the Radeon VII, which comes with core speeds of 1400 MHz on the GPU, and 1000 MHz on the 16384 MB of HBM2 RAM. It features 3840 SPUs along with 240 Texture Address Units and 64 ROPs.

Radeon VII 336000 Mtexels/sec
GeForce GTX 1660 Ti 144000 Mtexels/sec
Difference: 192000 (133%)

Pixel Rate

The Radeon VII should be quite a bit (more or less 24%) better at AA than the GeForce GTX 1660 Ti, and able to handle higher resolutions without losing too much performance. (explain)

Radeon VII 89600 Mpixels/sec
GeForce GTX 1660 Ti 72000 Mpixels/sec
Difference: 17600 (24%)

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 largest amount of information (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
