AMD took the stage at yesterday’s CES 2021 keynote to announce the laptop versions of its latest Ryzen 5000 CPUs. The newly announced chips also include 35-watt versions which will directly compete with Intel’s 11th Gen Tiger Lake H35 CPUs announced this week.
The 35-watt version CPUs are aimed at thin and light gaming laptops, whereas the low power U series is meant for mainstream laptops with a lightweight design. Just like Intel, the H series includes high-powered processors, and there is also an HX series that can be overclocked to go beyond their base 45W power rating for better performance.
|Cores/threads||TDP||Base clock||Single-core boost clock|
|Ryzen 9 5980HX||8/16||45+w||3.3||4.8|
|Ryzen 9 5980HS||8/16||35w||3.0||4.8|
|Ryzen 9 5900HX||8/16||45+w||3.3||4.6|
|Ryzen 9 5900HS||8/16||35w||3.0||4.6|
|Ryzen 7 5800H||8/16||45w||3.2||4.4|
|Ryzen 7 5800HS||8/16||35w||2.8||4.4|
|Ryzen 5 5600H||6/12||45w||3.3||4.2|
|Ryzen 5 5600HS||6/12||35w||3.0||4.2|
|Ryzen 7 5800U||8/16||15w||1.9||4.4|
|Ryzen 7 5700U||8/16||15w||1.8||4.3|
|Ryzen 5 5600U||6/12||15w||2.3||4.2|
|Ryzen 5 5500U||6/12||15w||2.1||4.0|
|Ryzen 3 5300U||4/8||15w||2.6||3.8|
It is worth mentioning that not all processors in the list are based on AMD’s new Zen 3 architecture. Out of all the U series chips, only the Ryzen 7 5800U and Ryzen 5 5600U are based on Zen 3, whereas the rest of them feature Zen 2, which featured on last year’s Ryzen 4000 Mobile CPUs.
There are a number of differences between Zen 2 and Zen 3, the biggest one being better performance per watt on Zen 3, which means better battery life. Zen 3 chips are also much more efficient than their Zen 2 counterparts.
As for performance compared to Intel chips, we will have to wait until actual models start coming in and third party benchmarks surface. Stay tuned for updates.
