GeForce GTX 570 vs Radeon RX 6500 XT

Intro

Compare all that to the Radeon RX 6500 XT, which has GPU core speed of 2200 MHz, and 4096 MB of GDDR6 RAM set to run at 2250 MHz through a 64-bit bus. It also features 1024 Stream Processors, 64 Texture Address Units, and 32 Raster Operation Units.

GeForce GTX 570		43920 Mtexels/sec
	Difference: 96880 (221%)

Pixel Rate

The Radeon RX 6500 XT should be a lot (about 140%) better at full screen anti-aliasing than the GeForce GTX 570, and will be able to handle higher resolutions while still performing well. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 570		29280 Mpixels/sec
	Difference: 41120 (140%)

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 max amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one 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 better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
