AMD’s (codenamed Rembrandt) Ryzen 6000 mobile processors were announced and launched over four months ago in January and February, but it seems mainstream adoption has been slow for the new line of processors. According to ComputerBase, only eleven laptops are currently using AMD’s new mobile processors in the four months since launch.
Of the eleven laptops released with Ryzen 6000 parts, eight of those systems are from Asus, with the other three coming from Razer, Lenovo, and Alienware respectively. This makes Asus by far the most dominant manufacturer to use these new processors, with Razer, Lenovo and Alienware only producing one SKU each with AMD’s new hardware.
This is an odd situation given that Rembrandt can, in theory, go hand in hand with Intel’s new Alder Lake mobile processors depending on the performance you’re looking for. Rembrandt comes with AMD’s new Zen 3+ microarchitecture that runs on TSMC’s 6nm node. Performance is expected to be up to 1.3x faster than the mobile Ryzen 5000 while being more efficient, with up to 50 new power management features added to the new architecture.
According to the AMD PR slides, all of these improvements add up to a 2.62X performance per watt improvement over Alder Lake CPUs (AMD specifically targeted the Core i9-12900HK and directly compared it to its own Ryzen 9 6900HS) .
When testing with an ROG Zephyrus G14 equipped with the new 6900HS, we found Rembrant’s performance to be quite competitive with laptops equipped with Intel’s i7-12700H, such as the Alienware x14 and Gigabyte Aorus 17. Alder Lake counterparts, with the 6900HS mostly losing out to the 12700H in heavy multi-threaded workloads. However, that’s to be expected given that the 12700H has more physical cores (although the extra cores are E-cores).
But the most impressive results come from the battery life tests we conducted. The 6900HS-powered G14 managed a whopping 10 hours and 14 minutes of battery life. While the 12700H counterparts could only reach 4-5 hours respectively.
So while Rembrandt is weak on the multi-threaded side of the equation, he’s still very strong in single-core situations. While consuming much less energy than it seems with our test of the G14. Arguably, these two attributes combined make for a superior gaming laptop anyway, as games are more susceptible to single-core IPC, and the long battery life is a welcome sight for any device designed to be used on the go.
So there are benefits for laptop makers to use AMD’s new CPU architecture on Alder Lake, but it seems almost no one is taking advantage of AMD’s potential. With the exception of Asus.
Ryzen 6000U series CPUs and Radeon RX 6000M GPUs are completely missing
But the story does not end there. ComputerBase also notes that AMD’s entire line of 6000U-series processors are completely absent from the retail market, with no laptop makers using the new chips. The same goes for AMD’s Radeon RX 6000M line of GPUs, all of which are conspicuously absent from any gaming laptop on the market today.
The only exception to this is AMD’s Radeon RX 6000S series products, including the RX 6700S and RX 6800S. These GPUs are commercially available in the Asus ROG Zephyrus G14, like the one we reviewed not too long ago.
Arguably, the availability issues might be more related to TSMC and AMD than the laptop manufacturers. We’ve known for some time that TSMC is one of the busiest factories in the world and struggles to get enough wafers to their customers in a timely manner, including orders for AMD.
Intel, on the other hand, doesn’t suffer from this problem since it builds everything in-house and has its own fabs. On the contrary, it looks like Intel has too much manufacturing firepower on the table, now that the company is agreeing to produce chips for other companies.
However, these theories are just that – theories – as AMD has been silent on the matter. But hopefully we will have more information about the issues soon. AMD plans to bring Zen 3+ to the AM5 desktop platform later this year, which should hopefully lead to a new announcement discussing more Zen 3+ with more integration-related announcements OEM.
