GeForce GTX 660 vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which features a core clock speed of 2200 MHz and a GDDR6 memory frequency of 2250 MHz. It also features a 64-bit memory bus, and uses a 6 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 660		140 Watts
	Difference: 33 Watts (31%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6500 XT should be just a bit faster than the GeForce GTX 660 overall. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 660		144192 MB/sec
	Difference: 3264 (2%)

Texel Rate

The Radeon RX 6500 XT will be much (about 80%) faster with regards to AF than the GeForce GTX 660. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 660		78400 Mtexels/sec
	Difference: 62400 (80%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6500 XT is superior to the GeForce GTX 660, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 660		23520 Mpixels/sec
	Difference: 46880 (199%)

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 information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
