Geforce GTX 1080 Ti vs Radeon RX 7900 XTX

Intro

Compare all that to the Radeon RX 7900 XTX, which comes with GPU clock speed of 1855 MHz, and 24576 MB of GDDR6 memory set to run at 2500 MHz through a 384-bit bus. It also features 6144 Stream Processors, 384 Texture Address Units, and 192 ROPs.

Radeon RX 7900 XTX		355 Watts
	Difference: 105 Watts (42%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 7900 XTX is 98% faster than the Geforce GTX 1080 Ti in general, because of its greater bandwidth. (explain)

Radeon RX 7900 XTX		983040 MB/sec
Geforce GTX 1080 Ti		495616 MB/sec
	Difference: 487424 (98%)

Texel Rate

The Radeon RX 7900 XTX should be a lot (about 115%) better at AF than the Geforce GTX 1080 Ti. (explain)

Radeon RX 7900 XTX		712320 Mtexels/sec
Geforce GTX 1080 Ti		331520 Mtexels/sec
	Difference: 380800 (115%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 7900 XTX is a better choice, by far. (explain)

Radeon RX 7900 XTX		356160 Mpixels/sec
Geforce GTX 1080 Ti		130240 Mpixels/sec
	Difference: 225920 (173%)

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 (counted in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant 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.
