GeForce GTX 660 vs Radeon RX 6950 XT

Intro

Compare all of that to the Radeon RX 6950 XT, which has a core clock frequency of 1925 MHz and a GDDR6 memory frequency of 2250 MHz. It also makes use of a 256-bit bus, and uses a 7 nm design. It is made up of 5120 SPUs, 320 Texture Address Units, and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 660		140 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 195 Watts (139%)

Memory Bandwidth

The Radeon RX 6950 XT should in theory be much faster than the GeForce GTX 660 in general. (explain)

Radeon RX 6950 XT		589824 MB/sec
GeForce GTX 660		144192 MB/sec
	Difference: 445632 (309%)

Texel Rate

The Radeon RX 6950 XT will be quite a bit (about 686%) more effective at AF than the GeForce GTX 660. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce GTX 660		78400 Mtexels/sec
	Difference: 537600 (686%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6950 XT is superior to the GeForce GTX 660, and very much so. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce GTX 660		23520 Mpixels/sec
	Difference: 222880 (948%)

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 information (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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