For years now, AMD barely mattered in the laptop space, and even if their platforms have improved in recent years, they’ve always been the lower-tier budget alternatives for the Intel Core H platforms.

Not anymore, though. As of Spring 2020, Ryzen 4000 Mobile platforms are available in stores and boy they change everything.

This article is a review of the Ryzen 7 4800H platform, the mid-range APU that replaces last year’s Ryzen 7 3750H and competes with the Intel 9th and 10th gen Core H i7s. We’re not going to get much in-depth on the specs and particularities, you’ll find them on AMD’s site and in the quick sheet down below. Instead, we’ll focus on benchmarks results, have a look at how this platform performs in demanding loads and in games when paired with mid-range RTX 2060 graphics, as well as how it handles daily use in terms of thermals and efficiency.

That aside, we’ll also pitch this against the lower-tier Ryzen 5 4600H processor and the previous Ryzen 7 3750H. We’ve left the AMDF HS and the Intel options out of this, as we’re covering those in separate articles that should be available on the site shortly.

Ok, so first off, the specs sheet for the Ryzen 7 4800H APU.

The updated Renoir Ryzen 4000 platforms offer not just a significant increase in core/thread count over the Ryzen 7 3750H, but also improved IPC and multiple other various optimizations, as well as a more powerful Vega iGPU implementation. That’s not going to matter much though, as Ryzen H APUs are always bundled with some sort of dedicated GPU that will handle the demanding graphics loads instead.

— developing, come back in an hour or two for the final version

As far as the performance goes, let’s jump straight into the demanding CPU loads. We’ve ran tests on two different Ryzen 7 4800H notebooks from Asus, which offer a Turbo power profile that increases the CPU’s power allocation in demanding loads. That’s similar for Intel platforms, just keep in mind that not all notebook are created equally, and some might not be as generous.

For the first test, we’re running Cinebench R15 for 15+ loops on these Turbo profiles, which set a TDP of 54W for these Ryzen 7 4800H. That’s allowing them to run at higher clocks than on a standard 45W implementation. However, Asus also offers a Performance profile which tames down the fans and sets a lower 35W TDP, and we’ve included both results down below, as a general reference of what to expect from various implementations on this Ryzen 7 4800H platform.

 

And here’s a quick comparison between these several AMD platforms. These results are based on the Ryzen 7 4800HS in the Asus ROG Zephyrus G14 , the Ryzen 5 4600H in the Asus TUF Gaming A15 FA506IU, and the Ryzen 7 3750H results on the Asus TUF Gaming FX505VD. We haven’t properly logged our findings for the 35W 4800H implementation, so we’ll update that in a future article.
