Got my 7nm Navi RX5700XT 50th Anniversary edition.

After reading the above I was expecting noise. Its quiet during normal gaming. Its virtually quiet under heaviest load in a closed gaming case that has audible cooling fans. Not a bother to me. In my system its far quieter than my Powercolor RX Vega 64. The PC Vega 64 is one of the fastest Vega 64s made. Has 3 fans -- can be noisy.

I wanted the RX5700XT 50th to out perform the Vega 64 by 20 percent (and hoped for 25 percent).

In basic Time Spy it was 25 percent faster. In Time Spy 4K it was only 18 percent faster (and far quieter). But, Time Spy is not a game, its a benchmark.

I personally like the Assassin's Creed Odyssey in-game benchmark -- its a low fly over of a graphics intensive part of the game. Its a game I play. I was pleasantly surprised (more like incredulous) when the in-game benchmark ran 32 percent faster at 4K and 115% field of view. So, I get the FPS improvement without the occasional in-game noise.

For completeness, in my heavily modded Fallout 4 worst scene (CPU limited) running at 4K, the FPS increase was small (as expected with a CPU limited scene).

These were preliminary tests. So far, overall, RX5700XT 50th wins for my uses. Other folks may get different results. I'll be interested to see how the numbers change when I'm running in my "new" computer (Ryzen 7 3800X) next week. I'd expect a real game to run even faster (if only slightly) -- maybe that Fallout 4 scene will improve.
