Two tech enthusiasts, Pieter "SkatterBencher" Plaisier and Roman "Der8auer" Hartung, recently made some exciting progress with AMD's new Ryzen 7 8700G. Skatterbencher focused on boosting the integrated GPU (iGPU) within the CPU, which happens to be a Radeon 780M.
If you're curious about that GPU, it's the same one found in both the Ryzen 7000 Mobile series processors and the Ryzen Z1 SoC designed for gaming handheld consoles, currently featured in devices like the ASUS ROG Ally and Lenovo Legion Go. The Radeon 780M in the 8700G boasts a default boost clock of 2.9GHz on paper but is built on the more power-efficient 4nm process node from TSMC. Notably, it also supports FidelityFX Super Resolution (FSR).
In SkatterBencher's hands, the boost clock of the Radeon 780M within the 8700G was pushed to 3.3GHz. It's worth mentioning that using the chipset's Precision Boost Overdrive (PBO) alone can overclock it to 3.15GHz, just 50MHz shy of their achieved overclock. The voltage was set at a modest 1.25V.
Unfortunately, SkatterBencher didn't share specific overclocking results for the 8700G and its iGPU running at 3.3GHz. Instead, they shared performance figures from running it at 3.15GHz, with the highest score recorded in the AI Benchmark.
Switching gears to Team Der8auer, the renowned German overclocker took a different approach. They delidded their 8700G, removing the original Thermal Interface Material (TIM) and replacing it with a fresh layer of liquid metal. Surprisingly, this process was easier compared to other Ryzen CPUs, thanks to the use of thermal compound instead of solder in this particular processor.
Der8auer's additional tweaks involved manually setting all cores to run at an impressive 5GHz. The outcome was a temperature drop for the 8700G, running at 60°C, a significant 20°C cooler than the stock temperature before the lid was removed and the thermal compound was replaced with liquid metal.
