GeForce GTX 1660 Ti vs Radeon RX 5700

Intro

Compare those specifications to the Radeon RX 5700, which has a clock speed of 1465 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
Radeon RX 5700		180 Watts
	Difference: 60 Watts (50%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 should be 56% faster than the GeForce GTX 1660 Ti overall, because of its greater data rate. (explain)

Radeon RX 5700		458752 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 163840 (56%)

Texel Rate

The Radeon RX 5700 will be quite a bit (about 47%) faster with regards to AF than the GeForce GTX 1660 Ti. (explain)

Radeon RX 5700		210960 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 66960 (47%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5700 is the winner, and very much so. (explain)

Radeon RX 5700		93760 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 21760 (30%)

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 transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
