AMD Ryzen 7 8700G APU Gets Die Close-Ups In First Delidding Treatment, Drops Temps By 25C

AMD's Ryzen 7 8700G APU has been delidded by hardware expert, Der8auer, showcasing its die & also a huge reduction in temps.

Delidding is a method employed by several consumers where it involves removing the CPU IHS (Integrated Heat Spreader), along with utilizing a more "premium" form of thermal paste, such as liquid metal. It is mainly done to achieve lower temperatures in the case of high-stress workloads, but Der8auer is known to delid every other flagship CPU release, similar to what we saw with Intel's Core i9-14900K. This time, he has decided to experiment on the AMD's Ryzen 7 8700G APU, and the overall process is pretty interesting.

To start the delidding process, Der8auer utilized the "delidding tool" from Thermal Grizzly, and fortunately enough, it worked perfectly despite being designed for the Ryzen 7000 series. This is because the Ryzen 7000 and Ryzen 8000G CPUs share the same IHS and chip dimensions with the only differences on the PCB.

After removing the IHS, a comparison has been made with AMD's Ryzen 9 7900X CPU, and as expected, the Ryzen 7 8700G APU didn't feature any single CCDs or I/O die, which is similar to what we see in a mobile lineup. The AMD APUs feature a monolithic design with all cores and I/O within the same die. Moreover, the AMD Ryzen 7 8700G APU doesn't feature a soldered design and instead utilizes a TIM application between the IHS and the die, and to compensate for the lower height of the die, AMD has brought in elevation in the center of the IHS, and it does the job.

Der8auer then proceeded to measure the die height of the AMD Ryzen 7 8700G APU, and interestingly, it was recorded around 0.5mm, which does reveal the fact that existing direct die products won't work with the Hawk Point APUs since they were designed for the Ryzen 7000 series, which came at a die height of 0.8mm. However, looking at the broader perspective, APU delidding doesn't have much potential in market sales, and Der8auer has mentioned that he probably won't release a direct die tool compatible with the Hawk Point APUs.

Finally, Der8auer experimented with the thermal performance of the AMD Ryzen 7 8700G by using Thermal Grizzly's Kryosheet graphene thermal pads, and upon synthetic benchmarking, a noticeable drop in temperatures was witnessed with Kryosheet onboard, with an average drop of around 10 degrees.

Next comes the application of liquid metal, and as expected, the results obtained were phenomenal since the temperature drop with LM was much higher than what we saw with graphene thermal pads.

The APU delidding process was indeed an interesting one, and while this implementation wouldn't have much of a benefit when you are using a decent cooling solution, delidding certainly comes in handy when you confine your APU into a smaller setup, with constraints involving the cooling solution to be used. Delidding the AMD Ryzen 7 8700G APU managed to reduce the thermals by up to 25 degrees, along with a decent bump in clock speeds as well, which shows the potential encaptivated in the process.
