GeForce GTX 1660 Ti vs Radeon RX 6700 XT

Intro

The GeForce GTX 1660 Ti features a clock speed of 1500 MHz and a GDDR6 memory speed of 1500 MHz. It also uses a 192-bit bus, and uses a 12 nm design. It is comprised of 1536 SPUs, 96 TAUs, and 48 Raster Operation Units.

Compare those specs to the Radeon RX 6700 XT, which features GPU core speed of 2321 MHz, and (Unknown) MB of GDDR6 RAM running at 2000 MHz through a 192-bit bus. It also features 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti 120 Watts
Radeon RX 6700 XT 230 Watts
Difference: 110 Watts (92%)

Memory Bandwidth

The Radeon RX 6700 XT should in theory perform a lot faster than the GeForce GTX 1660 Ti in general. (explain)

Radeon RX 6700 XT 393216 MB/sec
GeForce GTX 1660 Ti 294912 MB/sec
Difference: 98304 (33%)

Texel Rate

The Radeon RX 6700 XT should be much (approximately 158%) more effective at anisotropic filtering than the GeForce GTX 1660 Ti. (explain)

Radeon RX 6700 XT 371360 Mtexels/sec
GeForce GTX 1660 Ti 144000 Mtexels/sec
Difference: 227360 (158%)

Pixel Rate

The Radeon RX 6700 XT should be quite a bit (more or less 106%) better at FSAA than the GeForce GTX 1660 Ti, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6700 XT 148544 Mpixels/sec
GeForce GTX 1660 Ti 72000 Mpixels/sec
Difference: 76544 (106%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 can be processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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