GeForce GTX 1660 Ti vs Radeon VII

Intro

The GeForce GTX 1660 Ti makes use of a 12 nm design. nVidia has clocked the core frequency at 1500 MHz. The GDDR6 RAM works at a frequency of 12000 MHz on this particular card. It features 1536 SPUs along with 96 TAUs and 48 ROPs.

Compare those specs to the Radeon VII, which features a core clock speed of 1400 MHz and a HBM2 memory frequency of 1000 MHz. It also makes use of a 4096-bit bus, and uses a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 64 ROPs.

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 theoretically be quite a bit better than the GeForce GTX 1660 Ti in general. (explain)

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

Texel Rate

The Radeon VII will be much (about 133%) more effective 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

If running with lots of anti-aliasing is important to you, then the Radeon VII is the winner, and very much so. (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 maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
