In fact, the first detail that immediately catches the eye is the reduction of the dimensions that go from 285x115x51 mm of the original to 281x117x40mm. The result was achieved thanks to the use of a thinner heatsink which allowed the device to now occupy only two expansion slots on the motherboard. Fortunately, the triple fan cooling system has been maintained, which allows for optimal performance even at higher operating frequencies than the factory ones.
From the power point of view, there are always two PCIe connectors (one 8-pin and the other 6-pin), but this time they have been moved to a new location, more precisely in the center of the graphics card, which, however, could lead to more problematic cable management than in the past . The design of the rear backplate has also been changed, which should now allow for more efficient heat dissipation.
Below is a comparison of the two revisions made by @ harakaze5719.
Unfortunately, to verify the difference in performance compared to revision 1.0 you will need to get your hands on it. Using a smaller form factor might be welcomed by those who want more compact systems (and will likely allow Gigabyte to reduce manufacturing costs), but it could also decrease the product's overclocking potential.
If you are looking for a good motherboard for your new configuration based on AMD Ryzen processors, on Amazon you will find the Gigabyte X570 AORUS ELITE at an attractive price.
