GeForce GTX 1660 Ti vs Radeon VII

Intro

Compare all that to the Radeon VII, which features clock speeds of 1400 MHz on the GPU, and 1000 MHz on the 16384 MB of HBM2 memory. It features 3840 SPUs as well as 240 Texture Address Units and 64 Rasterization Operator 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

The Radeon VII should in theory be quite a bit faster 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 (about 133%) faster with regards to AF 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 much (more or less 24%) better at full screen anti-aliasing than the GeForce GTX 1660 Ti, and will be able to handle higher resolutions better. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
