AMD hasn't officially announced a Ryzen 9 4900HS, but it's most likely a member of the Ryzen 4000-series (codename Renoir) family of APUs. Renoir chips are based on the Zen 2 microarchitecture and manufactured with TSMC's 7nm FinFET process. The processors natively support DDR4-3200 desktop RAM and LPDDR4-4266 laptop memory standards.

The default TDP (thermal design power) for H-series models is 45W. However, the APUs also feature a configurable TDP range that spans from 35W to 54W. The HS-series, which are exclusive to Asus for the first six months, are specced for 35W.

Sadly, the listing doesn't give us any insight on the Ryzen 9 4900H's integrated graphics. The Ryzen 9 series is expected to employ the same Radeon Vega 7 graphics solution seen on the Ryzen 7 series, pointing to seven compute units (CUs). There is also a rumor floating around that the Ryzen 9 series could carry up to eight CUs.
Laptop manufacturers will probably employ the Ryzen 9 series SKUs in their high-end devices, so the integrated graphics shouldn't hold much value. In Asus' case, the company paired the Ryzen 9 4900HS with a Nvidia GeForce RTX 2060 Max-Q graphics card, 16GB of memory and a 1TB SSD for storage.
Atlex lists the Asus latest ROG Zephyrus G14 for 9,150 Romanian Leu, which roughly translates to $2,066. The Romanian retailer doesn't say when the gaming laptop will be available.
