GeForce GTX 660 Ti vs Radeon RX 6700 XT

Intro

Compare all of that to the Radeon RX 6700 XT, which uses a 7 nm design. AMD has set the core frequency at 2321 MHz. The GDDR6 memory works at a speed of 2000 MHz on this particular model. 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 6700 XT		230 Watts
	Difference: 80 Watts (53%)

Memory Bandwidth

In theory, the Radeon RX 6700 XT will be 173% quicker than the GeForce GTX 660 Ti in general, because of its greater data rate. (explain)

Radeon RX 6700 XT		393216 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 249216 (173%)

Texel Rate

The Radeon RX 6700 XT should be much (about 262%) more effective at texture filtering than the GeForce GTX 660 Ti. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 268880 (262%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6700 XT is the winner, and very much so. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 126584 (576%)

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 maximum amount of information (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
