i9 7900X @ 5GHz... no LN2 required

Mon Jun 12, 2017 12:11 pm

So the der8aur guy who make delidding kits posted a video of a delidded 7900X running all 10 cores at 5 GHz while running a compute-intensive workload (Prime 95 FFTs): https://www.youtube.com/watch?v=80sEZSODwpw

Apparently this sample was hitting 4.8 GHz even before he delidded it. Now, this chip was binned so there's no guarantee that most 7900X parts will run this fast, but he did mention that he expects delidded 7900X parts to average in the 4.6 to 4.7 GHz range with a good AIO cooler solution, which isn't too shabby.

Incidentally, at 1:55 in the video you see some stats on the screen and the core voltage is listed at 1.32V, which ain't bad for 5GHz either.
4770K @ 4.7 GHz; 32GB DDR3-2133; GTX-1080 sold and back to hipster IGP!; 512GB 840 Pro (2x); Fractal Define XL-R2; NZXT Kraken-X60

Geez Wiz what can we do with all of that performance...?

I hate to see the resulting TDP wattage on that overclocked CPU.

Let's not get too carried away here...

That's hardly a surprise since normal Skylake silicon has similar overclocking potential under water-cooling and delidding.

I'm wondering if the 10 core i9 CPU would be the best selling one of the i9 series since it can be overclocked to 5000 Mhz?
