Tipster @TUM_APISAK outs specs for the rumored Ryzen 7 4800H. The APU will supposedly feature eight cores, sixteen threads, and sport 2.9 GHz/4.3 GHz base/boost clocks. 3DMark Physics scores indicate that it's set to become one of the fastest laptop CPUs on the market.

Rumors about the Ryzen 7 4800H and 4900H have been doing the rounds over the past week. Earlier, we covered a Mobile01 thread where initial details about the two mobile APUs were discussed. They're evidently set to be eighth-core, sixteen-thread parts that will take the fight to Intel's i9-9980H in the high-end notebook space.

Today, tipster @TUM_APISAK was spotted sharing possible specs for the Ryzen 7 4800H. The tipster's post states that the Ryzen 7 4800H will feature eight cores and sixteen threads. This correlates with the original rumor on Mobile01. The new leak goes a step further by providing base and boost clocks as well as the Ryzen 7 4800H's purported 3DMark Physics score.

According to @TUM_APISAK, the Ryzen 7 4800H will have a 2.9 GHz base clock and a 4.3 GHz boost clock. This is substantially higher than the Ryzen 7 3750H, which has a 2.3 GHz base clock and 4.0 GHz boost clock. Unlike the latter Zen+ part, the Ryzen 7 4800H is almost certainly be based on Zen 2 and built on the 7nm process, enabling the higher clockspeeds. Together with the gains in IPC, this will give the Ryzen 7 4800H a substantial edge in both single and multi-threaded workloads.

This is backed up by the third part of this leak: the alleged 3DMark Firestrike Physics score for the Ryzen 7 4800H. While the score listed in the leak has not been verified, @TUM_APISAK has a reliable track record. The leak indicates that the Ryzen 7 4800H scored in the 19,000 range on 3DMark physics. This is 2000 points higher than the i9-9880H, one of the fastest Coffee Lake H processors. It's also within spitting distance of the ultra high-end i9-9980HK.

If the current leak is accurate, the Ryzen 7 4800H is set to become among the fastest laptop CPUs on the market. We will keep you posted with further updates as they come in.
