AMD Pinnacle Ridge CPUs to have soldered IHS
Not thermal paste like Raven Ridge APUs [Ryzen 5 2400G]
In the aftermath of Raven Ridge delidding, which revealed that it uses thermal paste under the IHS, AMD's Robert Hallock took to Reddit to note that this won't be the case with the upcoming Pinnacle Ridge CPUs, based on 12nm manufacturing process and usually known as the Ryzen 2 CPUs.
Hallock added that TIM made the most sense for the performance and thermal characteristics of the Raven Ridge APU design, describing it as the right tool for the right job. He also was quite keen to note that "a pure processor, designed for enthusiast gaming machines, plays in a different market" and as such has "different prices, different thermal and mechanical requirements", which is why the second generation Ryzen, as he calls it, will use solder.
My Raven Ridge Ryzen 5 2400G easily overclocks to 4GHz on all cores all the time.
However, after a few minutes in a stress test (e.g. Prime95), the temperature is climbing above 80C on standard cooling. The throttling limit is 95C according to the AMD overclocking software. I've read that 75C is safe for continuous use. I stop the test at 80C.
