It’s been a week since the official launch of AMD’s Ryzen 8000 series of APUs, and overclockers have had a week to tinker with the chips. It turns out the Ryzen 7 8700G has some decent overclocking headroom, particularly if you delid it, which will lower temperatures and allow it to be overclocked to Ryzen 7 7700X performance levels—or beyond. 

The test was run by Der8auer. He began by explaining why the Ryzen 8000-series chips don’t feature soldered thermal interface material (TIM), saying it’s because they are more closely related to mobile parts rather than higher TDP desktop parts. That makes sense given their 65W TDP. I’d add that it allows AMD to save a few cents. Given that a stock 8700G will run in the 80 to 90 degree range depending on your cooling capabilities, there’s little need for soldered heat spreaders under default operating conditions.

He then ran the same test with PBO enabled, followed by a test with a manual 5.0GHz overclock. This reveals the limitations of the stock TIM, with temperatures reaching into the 90s with some thermal throttling.

Next, Der8auer repeats the tests but with a Thermal Grizzly Kryosheet and liquid metal TIMs. This resulted in temperature drops of between 10 to 25 degrees. The final overclock saw a result of just over 20,000 in Cinebench R23’s multi thread test thanks to a 5.3GHz overclock at 1.37v. Temperatures stayed under 80 degrees.

It’s really impressive to see an overclocked and overvolted 8700G resulting in temperatures that are still below that of the chip running at default settings with its stock TIM. 

If nothing else, these tests show the stock TIM is pretty much rubbish. Of course, AMD will say that the chips run perfectly well within their designed temperature tolerances. That’s perfectly acceptable, but I like the idea of a chip running up to about 70 degrees rather than at 90+. It means a quieter system that doesn’t result in fans ramping up and down, which is something everyone can appreciate.

Of course, all of this is largely academic, since buyers of APUs are less likely to be interested in CPU overclocking than they are about the integrated graphics capabilities of the chip. Still, by lowering temperatures, it will allow users to get by with less capable cooling, which will benefit chips that go into small form factor systems with low profile coolers.

Personally, I have only bothered with delidding when shooting for maximum overclocks, but these kinds of tests really do show just how much cooler a delidded chip can run. I’ll give it some serious thought for my next build, whatever form that will take.
