AMD Ryzen 5000 Zen 3

CES 2021 is in full swing and AMD is here with “the most powerful PC processors ever built.” This is in reference to the 7nm Zen 3 architecture-based Ryzen 5000 mobile processors. There is two range of products viz. H-series for high-end gaming laptops and U-series for mainstream ultraportables.

The highest-order product from H-class is Ryzen 9 5980HX, while from the U-team there is Ryzen 7 5800U. Let’s take a look at the specs and numbers now.

AMD Ryzen 5000 Mobile: H-Series

The Ryzen 9 5980HX with its 8 cores (in a single block), 16 threads, 20MB of L2+L3 shared cache, and a top clock speed of 4.6GHz is touted as the “ultimate performance” engine for gaming laptops. They boast thermal headroom of up to 45+ watts TDPs. Further, they will be overclock-ready too.

The GPU is the same as its predecessor, although AMD has teased RDNA2-based graphics for laptops and mid-range desktops later this year.

The Ryzen HX 5000-series laptops boast 4K gaming prowess, and class-leading single as well as multi-threaded performance. For now, these are claimed to be better than Intel’s Tiger Lake H counterparts.

AMD Ryzen 5000 Mobile: U-Series

Ryzen 3 5300U4C / 8T2600380015WZen2

As you can see from the above table, there are still few U-series processors that are fabbed on Zen 2 microarchitecture. The reasoning is particularly not clear at the moment.

Meanwhile, the Zen-3 based Ryzen 7 5800U claims single-threaded performance gains of up to 16% and up to 17.5 hours of battery endurance.

You could expect at least 150 different laptop variants from brands like Asus, Acer, Dell, HP, and Lenovo this year starting from quarter 1.

Lastly, AMD has also announced 3 new Ryzen Threadripper PRO CPUs (with up to 64 cores, 8 channel RAM slot, 128 PCIe 4 storage lanes, and integrated AMD PRO security features) and Ryzen 5000 series desktop processors (12-core Ryzen 9 5900 and the 8-core Ryzen 7 5800).
