I'm curious about how much the RTX 5090 outperforms the RTX 4090 in Bitcoin private key cracking speed. In programs like bitcrack, keyhunt, and vanbitcracken, the 4090 reaches around 4 Gkeys/s. So far, I haven’t found specific data on the RTX 5000 series for this niche test. However, I came across a post on the Hashcat forum suggesting that in one mode, the 5090 might be up to three times faster than the 4090. The best way to get a definitive answer is probably to ask on that forum—some users likely already have 5000-series GPUs, whether it's a 5090, 5080, or even a 5070.
