Gigabyte air cooled cards are weird - they are the biggest but never have the best performance. You can look at the 2080ti, 3090, 4090 etc it don't matter - the gigabyte master is always huge, but only has middle of the pack performance.
I don't know what goes on at Gigabyte, but I suspect they don't have the best engineers
Yeah it's strange. The Aorus should perform similarly to the ROG Strix for example, but it doesn't. It's louder and has worse temperatures.
Maybe Gigabyte have improved things for the 5000 series? Either way I don't like their designs personally.
