GeForce GTX 550 Ti vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which has clock speeds of 2200 MHz on the GPU, and 2250 MHz on the 4096 MB of GDDR6 memory. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 9 Watts (8%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6500 XT should be 50% faster than the GeForce GTX 550 Ti overall, because of its higher bandwidth. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 550 Ti		98496 MB/sec
	Difference: 48960 (50%)

Texel Rate

The Radeon RX 6500 XT will be quite a bit (approximately 389%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 112000 (389%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6500 XT is the winner, by a large margin. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 550 Ti		21600 Mpixels/sec
	Difference: 48800 (226%)

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 megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
