GeForce GTX 780 Ti vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which makes use of a 6 nm design. AMD has set the core speed at 2200 MHz. The GDDR6 memory works at a frequency of 2250 MHz on this specific card. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 143 Watts (134%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 780 Ti will be 128% faster than the Radeon RX 6500 XT overall, due to its higher bandwidth. (explain)

GeForce GTX 780 Ti		336000 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 188544 (128%)

Texel Rate

The GeForce GTX 780 Ti should be a lot (more or less 49%) better at AF than the Radeon RX 6500 XT. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 69200 (49%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6500 XT is a better choice, by far. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 28400 (68%)

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 max amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
