GeForce GTX 980 Ti vs Radeon RX 7900 XTX

Intro

Compare all of that to the Radeon RX 7900 XTX, which features GPU core speed of 1855 MHz, and 24576 MB of GDDR6 RAM set to run at 2500 MHz through a 384-bit bus. It also is made up of 6144 Stream Processors, 384 Texture Address Units, and 192 Raster Operation Units.

GeForce GTX 980 Ti		250 Watts
Radeon RX 7900 XTX		355 Watts
	Difference: 105 Watts (42%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 7900 XTX should be 193% quicker than the GeForce GTX 980 Ti in general, because of its greater data rate. (explain)

Radeon RX 7900 XTX		983040 MB/sec
GeForce GTX 980 Ti		336000 MB/sec
	Difference: 647040 (193%)

Texel Rate

The Radeon RX 7900 XTX will be much (more or less 305%) better at AF than the GeForce GTX 980 Ti. (explain)

Radeon RX 7900 XTX		712320 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 536320 (305%)

Pixel Rate

The Radeon RX 7900 XTX will be quite a bit (approximately 271%) faster with regards to FSAA than the GeForce GTX 980 Ti, and also able to handle higher screen resolutions more effectively. (explain)

Radeon RX 7900 XTX		356160 Mpixels/sec
GeForce GTX 980 Ti		96000 Mpixels/sec
	Difference: 260160 (271%)

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 max amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
