GeForce GTX 1660 Ti vs Radeon Vega Frontier Edition

Intro

Compare those specs to the Radeon Vega Frontier Edition, which comes with a clock frequency of 1382 MHz and a HBM2 memory speed of 1890 MHz. It also makes use of a 2048-bit memory bus, and uses a 14 nm design. It is made up of 4096 SPUs, 256 Texture Address Units, and 64 ROPs.

GeForce GTX 1660 Ti		120 Watts
Radeon Vega Frontier Edition		300 Watts
	Difference: 180 Watts (150%)

Memory Bandwidth

As far as performance goes, the Radeon Vega Frontier Edition should in theory be quite a bit better than the GeForce GTX 1660 Ti in general. (explain)

Radeon Vega Frontier Edition		495452 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 200540 (68%)

Texel Rate

The Radeon Vega Frontier Edition is much (more or less 146%) better at AF than the GeForce GTX 1660 Ti. (explain)

Radeon Vega Frontier Edition		353792 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 209792 (146%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon Vega Frontier Edition is a better choice, by far. (explain)

Radeon Vega Frontier Edition		88448 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 16448 (23%)

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 data (measured in MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
