GeForce GTX 1660 Ti vs Radeon VII

Intro

The GeForce GTX 1660 Ti features a core clock speed of 1500 MHz and a GDDR6 memory speed of 1500 MHz. It also uses a 192-bit memory 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 VII, which has a clock frequency of 1400 MHz and a HBM2 memory frequency of 1000 MHz. It also features a 4096-bit bus, and makes use of a 7 nm design. It is made up of 3840 SPUs, 240 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti 120 Watts
Radeon VII 295 Watts
Difference: 175 Watts (146%)

Memory Bandwidth

As far as performance goes, the Radeon VII should in theory be much better than the GeForce GTX 1660 Ti overall. (explain)

Radeon VII 1048576 MB/sec
GeForce GTX 1660 Ti 294912 MB/sec
Difference: 753664 (256%)

Texel Rate

The Radeon VII should be quite a bit (more or less 133%) better at texture filtering than the GeForce GTX 1660 Ti. (explain)

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

Pixel Rate

The Radeon VII should be a lot (approximately 24%) better at AA than the GeForce GTX 1660 Ti, and should be able to handle higher screen resolutions without slowing down too much. (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: Bandwidth is the largest amount of information (counted in MB per second) that can be moved across 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 RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
