GeForce GTX 980 Ti vs Radeon RX 6750 XT

Intro

Compare those specs to the Radeon RX 6750 XT, which has a clock speed of 2150 MHz and a GDDR6 memory frequency of 2250 MHz. It also makes use of a 192-bit bus, and uses a 7 nm design. It is comprised of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Radeon RX 6750 XT should in theory be much better than the GeForce GTX 980 Ti in general. (explain)

Radeon RX 6750 XT		442368 MB/sec
GeForce GTX 980 Ti		336000 MB/sec
	Difference: 106368 (32%)

Texel Rate

The Radeon RX 6750 XT should be much (more or less 95%) faster with regards to texture filtering than the GeForce GTX 980 Ti. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 168000 (95%)

Pixel Rate

The Radeon RX 6750 XT should be much (approximately 43%) more effective at FSAA than the GeForce GTX 980 Ti, and able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
GeForce GTX 980 Ti		96000 Mpixels/sec
	Difference: 41600 (43%)

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 maximum amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the 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 core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
