GeForce GTX 660 Ti vs Radeon RX 5700 XT

Intro

Compare all of that to the Radeon RX 5700 XT, which uses a 7 nm design. AMD has set the core frequency at 1605 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this card. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 660 Ti		150 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 75 Watts (50%)

Memory Bandwidth

Theoretically, the Radeon RX 5700 XT should perform quite a bit faster than the GeForce GTX 660 Ti overall. (explain)

Radeon RX 5700 XT		458752 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 314752 (219%)

Texel Rate

The Radeon RX 5700 XT will be much (approximately 151%) faster with regards to AF than the GeForce GTX 660 Ti. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 154320 (151%)

Pixel Rate

The Radeon RX 5700 XT is quite a bit (about 368%) faster with regards to anti-aliasing than the GeForce GTX 660 Ti, and should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 80760 (368%)

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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at 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 could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
