Is Gemini correct here?

The Proportion of FP64:
​In Asteroids@Home, nearly 100% of the core compute-heavy tasks utilize FP64.
The project uses the Convex-Inversion method to derive the shapes and spin states of asteroids from photometric data. Because orbital mechanics and gravitational simulations require high numerical stability to avoid "drift" over long simulated timeframes, FP32 is insufficient

The Calculation:
​Raw Compute Factor: The Radeon VII has a native FP64 rate that is 4.5x higher than the WX 9100 (3.5 / 0.77 \approx 4.54).
​Memory Bandwidth Factor: Asteroids@Home is also notoriously memory-starved. The Radeon VII provides 2.1x more bandwidth, ensuring the compute units are fed data much faster.
​Estimated Performance Gain
​The Radeon VII is roughly 4 to 5 times faster than the WX 9100 Pro for Asteroids@Home.
​Because the MI50 you are setting up is a "pure" compute version of the Radeon VII with an even better 1:2 FP64 rate (~6.7 TFLOPS), it will likely double the performance of the Radeon VII again. You are essentially moving from a "workstation" level to a "supercomputer" level for this specific project

I don't put much trust in "theoreticals? Better data is achieved by actually deploying the hardware in an actual Boinc cruncher and see whether the applications can actually get any advantage from the new crunching hardware.

They're in the post, I'll let you know....

I thought someone might know how DP and memory hungry these tasks are.

Just for fun, here's a rig of old 280X cards, all refurbished by me to run cool.
