GeForce GTX 570 vs Radeon RX 6500 XT

Intro

Compare those specifications to the Radeon RX 6500 XT, which comes with core speeds of 2200 MHz on the GPU, and 2250 MHz on the 4096 MB of GDDR6 memory. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 570		219 Watts
	Difference: 112 Watts (105%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 570 should be 3% quicker than the Radeon RX 6500 XT overall, because of its greater data rate. (explain)

GeForce GTX 570		152000 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 4544 (3%)

Texel Rate

The Radeon RX 6500 XT is quite a bit (about 221%) better at texture filtering than the GeForce GTX 570. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 570		43920 Mtexels/sec
	Difference: 96880 (221%)

Pixel Rate

The Radeon RX 6500 XT will be quite a bit (more or less 140%) more effective at FSAA than the GeForce GTX 570, and will be capable of handling higher screen resolutions without slowing down too much. (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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core 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 the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
