GeForce GTX 1660 Ti vs Radeon VII

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 12000 MHz through a 192-bit bus. It also features 1536 Stream Processors, 96 TAUs, and 48 Raster Operation Units.

Compare that to the Radeon VII, which comes with a clock speed of 1400 MHz and a HBM2 memory frequency of 1000 MHz. It also uses a 4096-bit bus, and uses a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 64 Raster Operation Units.

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the Radeon VII should in theory be quite a bit superior to 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 is quite a bit (more or less 133%) better at anisotropic 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

If running with a high resolution is important to you, then the Radeon VII is superior to the GeForce GTX 1660 Ti, by a large margin. (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 max amount of data (counted in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video 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 maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
