GeForce GTX 980 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 is set to run at a frequency of 2000 MHz on this particular model. It features 2560 SPUs along with 160 TAUs and 64 Rasterization Operator Units.

GeForce GTX 980 Ti		250 Watts
	Difference: 20 Watts (9%)

Memory Bandwidth

In theory, the Radeon RX 6700 XT is 17% quicker than the GeForce GTX 980 Ti in general, due to its greater bandwidth. (explain)

Radeon RX 6700 XT		393216 MB/sec
GeForce GTX 980 Ti		336000 MB/sec
	Difference: 57216 (17%)

Texel Rate

The Radeon RX 6700 XT will be much (about 111%) faster with regards to AF than the GeForce GTX 980 Ti. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 195360 (111%)

Pixel Rate

If running with a high resolution 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 980 Ti		96000 Mpixels/sec
	Difference: 52544 (55%)

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 data (counted in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
