AMD Ryzen 9 3950X: Overclocked to 5 GHz Allcore faster than Intel Core i9
You've been able to read up on a lot of news and article about the pending Ryzon Series 3000 processors. The one proc that made a lot of news is, of course, the AMD Ryzen 9 3950X, however at the event, we attended there was live overclocking and thus the first OC and benchmark results are already in.
The 16-core with 32 threads and 72 MiByte L3-Cache proc is bound to set some records. The overclocking btw was done with LN2, as we do not see you get 16 cores at 5 GHz on LCS lol. So the base specs are as follows, the 16-core clocks has a moderate 3.5 GHz base clock but can boost to up to 4.7 GHz on individual cores. Tweaking this to all-cores 5 GHz certainly is going to bust that 105 watt TDP but when it was tweaked, they applied a gnarly OC trial at 1.608 volts and liquid nitrogen, 5.0 GHz was achieved on all 16 cores. Installed on an MSI MEG X570 Godlike and paired with G-Skill Trident Z Royal DDR4-4533, the team reached these records:
- Cinebench R15: Ryzen 9 3950X with 5,434 points (previously: Core i9-9960X with 5,320 points)
- Cinebench R20: Ryzen 9 3950X with 12.167 points (previously: Core i9-7960X with 10.895 points)
- Geekbench 4: Ryzen 9 3950X with 65.499 points (previously: Core i9-7960X with 60.991 points)
In addition, we can report that the AMD Ryzen 9 3950X has managed to operate DDR4-5100 on CL18-21-21-56. It is currently assumed that practical OC operation for normal use with DDR4-4266 is possible if an X570 motherboard is used. Standard is at Matisse DDR4-3200 and AMD will likely recommend 3866 MHz as default. I was able to snag some photos at the event when the tweaking was in progress.

Thats a pretty steep power increase there.
I know its 4.7 on one core vs 5 on all cores, but still.
It seems that as we get smaller and smaller process nodes, the power curve is much steeper at the top end.
weeks to go until the review NDA drops though....

Guess Intel and AMD just saving overclockers a hassle and already pushes hardware to its limits.
So if it says 4.7GHz, it's as far as it gets on the consumer grade cooling, no more room for OC without special equipment.

It's months for the 3950x unfortunately.

Well apparently Boost override can add an extra 200MHz but apparently you need an X570 motherboard to use it, maybe why so many X570 have no doublers and big phases 12+. Might be
part of the specification to have the phase frequency high so single phases are required for the boost override to function. I am going to use mine in a X370 for the time being intill i see a good X570.

therefore useless.
Ryzen 2700x been overclocked to 6GHz+ on LN2, it doesn't mean anything for 99.9999999% of consumers.
I think LN2 should be mentioned in the title. This sounds like bait, imo.
On the other hand, now we know that 5GHz is not happening on AIO or air.
