Data provenance
Community-reported hashrate at stock settings. Last verified 2026-07-31.
Note: GPU hashrate varies substantially with memory tuning, power limit and driver version. Treat this as a mid-range figure, not a guaranteed one.
Any field not listed above is one we could not verify for this machine. We would rather leave a row out than publish a figure you cannot check. Where published sources disagree, we say so instead of picking one. How we verify specifications.
