GeForce GTX 660 Ti vs Radeon RX 6950 XT

Intro

Compare that to the Radeon RX 6950 XT, which features GPU core speed of 1925 MHz, and 16384 MB of GDDR6 RAM set to run at 2250 MHz through a 256-bit bus. It also is made up of 5120 SPUs, 320 Texture Address Units, and 128 ROPs.

GeForce GTX 660 Ti		144000 MB/sec
	Difference: 445824 (310%)

Texel Rate

The Radeon RX 6950 XT should be much (more or less 501%) more effective at anisotropic filtering than the GeForce GTX 660 Ti. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 513520 (501%)

Pixel Rate

The Radeon RX 6950 XT should be much (about 1022%) better at full screen anti-aliasing than the GeForce GTX 660 Ti, and also capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 224440 (1022%)

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 largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
