Overclockers Pieter “SkatterBencher” Plaisier and Roman “Der8auer” Hartung made some headway with AMD’s new Ryzen 7 8700G. In Skatterbencher’s case, they focused on pushing the iGPU within the CPU, which is a Radeon 780M.
If you’re wondering why that GPU sounds familiar, it’s because that is the same iGPU that is found within both the Ryzen 7000 Mobile series processors, as well as the Ryzen Z1 SoC that was created primarily for gaming handheld consoles and is currently being used in devices such as the ASUS ROG Ally and Lenovo Legion Go. On paper, the Radeon 780M in the 8700G has a boost clock of 2.9GHz by default, but is based on the more power efficient 4nm process node from TSMC. Oh, and it also supports FSR.
SkatterBencher managed to push that boost clock of the Radeon 780M within the 8700G to 3.3GHz, although it should be noted that through the chipset’s Precision Boost Overdrive (PBO) alone, you can overclock it to 3.15GHz, which is only 50MHz higher. In this case, they set the voltage to just 1.25V.
Sadly, SkatterBencher did not share the overclocking results of the 8700G and its iGPU running at 3.3GHz, but did instead share the numbers achieved from running the latter at 3.15GHz, with the highest score shown in the AI Benchmark.
Over at Team Der8auer, the renowned German overclocker removed the lid from their 8700G, cleaned off the original Thermal Interface Material (TIM) and replaced it with a healthy, clean, layer of liquid metal. Apparently, this was easier than other Ryzen CPU, on account that it uses thermal compound, and not solder like the other processors.
Other parametres included manually setting all cores to run at 5GHz. The end result was the 8700G running at 60°C, which was 20°C cooler than the stock temperature before Der8auer removed the lid and switched out the thermal compound for liquid metal.
