GeForce GTX 1660 Ti vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which uses a 7 nm design. AMD has set the core speed at 1700 MHz. The GDDR6 memory is set to run at a frequency of 2000 MHz on this particular card. It features 3840 SPUs as well as 240 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
Radeon RX 6800		250 Watts
	Difference: 130 Watts (108%)

Memory Bandwidth

Theoretically, the Radeon RX 6800 should perform quite a bit faster than the GeForce GTX 1660 Ti overall. (explain)

Radeon RX 6800		524288 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 229376 (78%)

Texel Rate

The Radeon RX 6800 should be much (more or less 183%) faster with regards to AF than the GeForce GTX 1660 Ti. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 264000 (183%)

Pixel Rate

The Radeon RX 6800 will be quite a bit (approximately 127%) better at full screen anti-aliasing than the GeForce GTX 1660 Ti, and should be able to handle higher resolutions more effectively. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 91200 (127%)

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 max amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface 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 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
