AMD has just finally lifted the wraps off its flagship Ryzen 4000 series mobile processors and they are the Ryzen 9 4900H and Ryzen 9 4900HS.

We have known about these two processors for a while now but it's good to hear it officially from AMD.

AMD first unveiled its Ryzen 4000 mobile processors at CES 2020 earlier this year.

These processors are built on a 7nm process and feature AMD's Zen 2 architecture.

And according to AMD, its Ryzen 4000 mobile processors would provide 15% higher instructions per clock as well as higher clock speeds. It would also be up to 20% more power efficient and provide up to twice the performance per watt.

Here's a table showing the specifications of the two new Ryzen 4000 processors:

AMD Ryzen 9 4900H and 4900HS specs
Models Ryzen 9 4900H Ryzen 9 4900HS
Cores / Threads 8 / 16 8 / 16
Base clock 3.3GHz 3.0GHz
Turbo clock 4.4GHz 4.3GHz
L2 4MB 4MB
L3 8MB 8MB
GPU CUs 8 8
GPU clock 1750MHz 1750MHz
TDP 45W 35W

The Ryzen 9 4900H and Ryzen 9 4900HS have nearly the same frequencies but the latter has a lower rated TDP of 35W.

They are also special in that they are supposedly reserved for OEM partners that have worked with AMD and that AMD has validated the designs.

Presumably, we will see the HS chips in thinner notebooks that have specially designed coolers to make the most out of the HS chips, like the Zephyrus G14 from ASUS.

Along with the two new flagship processor additions, AMD has also expanded their Ryzen 4000 H-series processors for gamers and creatives, offering both 35W and 45W options across the processor tiers:-

Meanwhile, expect to see notebooks featuring the Ryzen 9 4900H and Ryzen 9 4900HS processors later this year.
