Sick overclock. It's cool to see Intel chips reach such new heights. It felt like we were stuck for 10 years. Hopefully as they get better at manufacturing and shrinking the 5GHz bar can be reliably passed.
My air (noctua) cooled 7900X sustains 12 cores at 5200MHz reliably, but it's honestly hard to find that much saturation, most tasks can run better with 8 cores sustaining about 5400, or 4 cores sustaining about 5500.
With better cooling I'd be surprised if I couldn't sustain 5400 on all 12 cores.
