GeForce GTX 660 Ti 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 bus, and uses a 6 nm design. It is made up of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 660 Ti		150 Watts
	Difference: 43 Watts (40%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6500 XT is 2% quicker than the GeForce GTX 660 Ti overall, because of its greater bandwidth. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 3456 (2%)

Texel Rate

The Radeon RX 6500 XT is quite a bit (about 37%) better at texture filtering than the GeForce GTX 660 Ti. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 38320 (37%)

Pixel Rate

The Radeon RX 6500 XT will be much (more or less 221%) better at anti-aliasing than the GeForce GTX 660 Ti, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 48440 (221%)

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 largest amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
