AMD Ryzen 7 8700G Gets 5 GHz All-core OC and 3.30 GHz iGPU OC in Separate Feats

[btarunr]

AMD Ryzen 7 8700G continues to be the favorite new toy for overclockers and enthusiasts. Der8auer succeeded in de-lidding the chip (removing its IHS), to reveal the monolithic "Hawk Point" silicon underneath. By default, the chip uses soldered TIM, but with the IHS removed and sTIM residue cleaned off, the chip could be prepared for direct die cooling, through liquid metal TIM. This feat enabled load temperatures to drop from 85°C to just over 60°C. This enabled a 5.00 GHz all-core overclock for the chip's 8 "Zen 4" CPU cores.

Also over the last week, SkatterBencher succeeded in getting the iGPU engine clock of the 8700G to 3.30 GHz, which is 50 MHz higher than the slider limit for Precision Boost Overdrive. SkatterBencher's report says that an 8700G can have its power limits raised all the way up to 170 W. The 3.30 GHz iGPU overclock was supported by a core voltage of 1.25 V (which is high considering the tight vCore limits AMD sets for its APUs). The increased power limits and clock speeds result in a 22.31% iGPU performance increase when averaged over 14 tests.

is 3.3ghz a record for a GPU? I can't think of any other GPU I have ever seen at that speed.

Not really, just last year there was a 4090 pushed past 4Ghz under liquid nitrogen. For an iGPU? Maybe.

Krayosheet (red line) enable some 12-15 degree less than stock, but don't come with the possible complications of metal past.

Above all, this test is a genuine good PR for that product (also was reviewed here at techoowerup).

Really? I was just about to ask if there's gonna be a review here, as I can't find it.

Those APUs actually use regular thermal paste, they're not soldered, that's why the gains from delidding are massive.

Thermal Grizzly KryoSheet Review - Tested on RX 7900 XTX with 475 W

Thermal Grizzly KryoSheet is an interesting alternative to thermal paste. The pre-cut sheet doesn’t dry out over time and you don’t have to try spreading it in a thin layer. In our review we test thermal performance on the AsRock RX 7900 XTX, at up to 475 W.

One thing stuck out to me was Kryosheet isnt reusable mentioned by Roman himself.

The CPU OC is 5.3GHz and not 5Ghz. That does around 20k CB23.

 

[Philaphlous]

Wonder if a KryoSheet is better than the PTM7950 stuff...interesting concept and might try for a laptop????

 

[DarkDreams]

The SkatterBencher graphs are incredibly misleading. The blue bars are missing 90% of their length. Easy way to make 20% improvement look like 300% I guess ...

 

[Ferrum Master]

benches are still made on the bugged AGESA, so chillax

 

[tommo1982]

They could make CPU's without heat spreader. It's nothing new, although mounting a cooler is not for everyone. It was common to chip the core on AMD Athlon's. Still I'd buy cuch a cpu.

Ah, you meant the Kryosheet! I meant the 8700G.

8700G was covered by handful of reviewers(AMD may not have seeded sample to most of the outlets) and I thought you were refering to Kryosheet which was used by Roman to compare against liquid metal for delid performance.

Nah, all RDNA3 can boost to those speeds momentarily but they're limited by power.
