AMD Ryzen 7 8700G Gets Delidded, 17% Faster With Significantly Lower Temps

For overclockers, delidding is a common practice for those seeking even more performance headroom as it improves thermal transfer – the presence of IHS (integrated heat spreader) is to enable a more reliable installation process, at a small but reasonable cost of thermal performance.

Naturally, this is what Roman ‘Der8auer’ Hartung does to AMD’s latest G-series chips, taking the Ryzen 8700G through the overclocking process. It was found that the thermal interface material (TIM) used for the Ryzen CPU is a regular thermal paste, which, while good at conducting heat in normal uses, isn’t the best when you’re looking to push the chip to its limits.

Hence, the process involves removing the thermal paste sandwiched between the chip and IHS, replacing it with liquid metal instead. This is compared against the chip in stock configuration – but Der8auer also performed a third benchmark run with a KryoSheet sandwiched in between to compare the results. All three tests are done with the CPU manually overclocked to 5.0GHz all core.

The results proved that liquid metal is indeed a great material for conducting heat – in the chart shown in the video, the liquid metal run (using Conductonaut Extreme) is a whopping 25°C cooler than the stock run, reducing the average CPU temperature down to just low 60 degrees. He then proceeds to push the chip to 5.3GHz, with temperatures in the 80s – more or less equal to the stock configuration. This results in a 15-17% improvement in Cinebench performance.

Previously, the Ryzen APU’s integrated GPU has also been overclocked courtesy of another overclocker, SkatterBencher – netting significant performance uplifts.

Pokdepinion: For how far modern CPUs push themselves to the limit these days, that’s a surprisingly large headroom available for conventional overclocking.
