AMD’s Zen 3+ CPUs are great, so why is no one using them?

A few months after the initial release of AMD’s Zen 3+ mobile processors, the CPUs are still hardly found in laptops.

Only 11 notebooks currently use AMD’s latest mobile chips. Is this slow adoption due to supply constraints or are there other reasons laptop makers haven’t picked up AMD Zen 3+?

‘Rembrandt’ stays behind

The AMD Ryzen 6000 mobile lineup of CPUs, codenamed “Rembrandt”, was launched more than four months ago. To call the new range of processors competitive would not be difficult at all. The chips offer some great specs coupled with balanced power consumption that makes them more energy efficient than their Alder Lake counterparts.

AMD has quite a few different chips in the Zen 3+ line, ranging from CPUs aimed at balancing power consumption and performance (Ryzen 5 6600U and Ryzen 7 6800U) to options that prioritize performance. Even those chips, divided into HX, HS and H-series, keep the TDP at a fairly pleasant maximum of over 45 watts.

The lineup includes more entry-level models like the Ryzen 5 6600HS, all the way up to the high-end Ryzen 9 6980HX that brings clocks up to 5.0GHz. In theory, there should be plenty of options to choose from, and these CPUs should find a home in some of the best gaming laptops, as well as slim notebooks made for working on the go.

Although benchmarks are still quite scarce, AMD made some promises about the performance of these chips when they announced it. The Rembrandt microarchitecture was said to deliver a performance increase of up to 1.3x over the previous Ryzen 5000 series. Perhaps more importantly, it reportedly delivers a massive 2.62x increase in performance per watt over Alder Lake CPUs.

Tom’s Hardware compared the performance of the AMD Ryzen 6900HS with the Intel Core i9-12700H and the results were favorable for AMD. The processor, housed in the Asus ROG Zephyrus G14, held its own in terms of performance and delivered a huge increase in battery life. Compared to the Alienware x14 and the Gigabyte Aorus 17 (both with Intel Core i7-12700H), the battery gains were huge – the Asus ROG Zephyrus G14 managed to last more than 10 hours on a single charge, while its Intel counterparts maxed out. out of about five hours.

AMD doesn’t talk

While it doesn’t get us to the next generation of chips just yet, the new AMD technology sounds pretty impressive. For some reason, the adoption of Zen 3+ technology in laptops has been very slow so far.

ComputerBase reported that only 11 notebooks are currently taking advantage of AMD’s new mobile offering. Four months after launch, that’s less than we expected. Asus has been the number one manufacturer to use Zen 3+ processors in its laptops, with eight new systems, while Lenovo, Razer and Alienware have only one each. Strangely enough, no manufacturer has yet picked up the energy-efficient AMD 6000U series.

AMD itself has not stated why it is so difficult to get its new Zen 3+ mobile CPUs. We’re still in the midst of a chip shortage, and since AMD relies entirely on TSMC to make these chips, supply chain issues may force laptop manufacturers to move to other options for now.

Another possible reason could be that manufacturers are already preparing for next-gen chips instead. Intel will release Raptor Lake processors this year, and AMD is also slated to launch Zen 4 in the third or fourth quarter of 2022. However, these chips may not be coming directly to laptops, so it seems there’s no reason more manufacturers should. does not want to give customers access to the (still competitive) Zen 3 refresh. AMD also recently released a successful refresh of Zen 3 desktop CPUs, including the excellent AMD Ryzen 7 5800X3D, but those chips can be used in DIY builds, so their adoption is harder to measure.

Without official word from AMD, it’s hard to say why the adoption of the Zen 3+ mobile lineup hasn’t been impressive. Since the chips seem to have a lot going for them, it would be great to see them popping up in more of the best laptops in 2022. Fortunately, it looks like we’ll be seeing a lot more of these laptops in the coming months, so hopefully the market will have a much wider range of Zen 3+ laptops by the end of the year.
