GeForce GTX 1660 Ti vs Radeon Pro Duo

Intro

Compare all of that to the Radeon Pro Duo, which has clock speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM memory. It features 4096 SPUs along with 256 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
Radeon Pro Duo		350 Watts
	Difference: 230 Watts (192%)

Memory Bandwidth

Theoretically, the Radeon Pro Duo should be quite a bit faster than the GeForce GTX 1660 Ti in general. (explain)

Radeon Pro Duo		1024000 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 729088 (247%)

Texel Rate

The Radeon Pro Duo should be a lot (about 256%) faster with regards to anisotropic filtering than the GeForce GTX 1660 Ti. (explain)

Radeon Pro Duo		512000 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 368000 (256%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon Pro Duo is the winner, by far. (explain)

Radeon Pro Duo		128000 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 56000 (78%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher 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 the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
