Rumour | Evidence of AMD Ryzen 9 4900H appears on 3DMark with a 4.4 GHz boost clock and an RX Vega 8 GPU

While AMD is yet to announce the Ryzen 9 4900H, more evidence of its existence has appeared online. Sporting a 45 W TDP, 8 cores and a 4.4 GHz boost clock, the Ryzen 9 4900H should have enough reserves to challenge whatever Intel and its Comet Lake-H series has to offer. Its Radeon RX Vega 8 integrated GPU may even challenge dedicated GPUs, too, thanks to its 8 compute units (CU) and its 1,750 MHz boost clock.

At this stage, it seems inevitable that AMD will release the Ryzen 9 4900H, its premier Ryzen 4000H series processor. As we saw last week courtesy of Videocardz, ASUS is planning to release a Ryzen 9 4900H-powered TUF Gaming laptop. However, the leak confirmed little else about the upcoming APU besides a supposed 4.2 GHz boost clock.

While this would have put the Ryzen 9 4900H at a clock speed disadvantage compared to the Ryzen 9 4900HS, for example, 3DMark suggests that the Ryzen 9 4900H is capable of exceeding 4.2 GHz. As the screenshot below demonstrates, 3DMark reports the APU as maxing out at 4.4 GHz, putting it on par with the Ryzen 9 4900HS. Both chips will apparently have 3.0 GHz base clocks too, which is unsurprising.

According to @_rogame, the Ryzen 9 4900H will likely only be able to reach 4.4 GHz with Precision Boost Overdrive (PBO), and that 4.3 GHz will be its effective maximum boost clock. Additionally, 3DMark reports that the APU's integrated GPU peaks at 1,750 MHz, effectively confirming that the Ryzen 9 4900H will have a Radeon RX Vega 8. This is an 8 CU part, for reference.

On top of that, the Ryzen 9 4900H will have a 45 W TDP, like its other Ryzen 4000H-series siblings. Expect to see the Ryzen 9 4900H arrive later this year in 15-inch gaming laptops.
