Acer Swift 3 (SF315-41G-R8Z5)
AMD’s Ryzen makes the move to mobile.
It’s debatable whether AMD has ever made a truly competitive laptop chip. Yes, AMD’s mobile processors based on the Bobcat core were OK for budget devices, but Intel’s domination has been even stronger in laptops than it already was on the desktop. But then Ryzen came along and proved how complacent Intel has become.
But that’s just desktop, right? No. At last, Ryzen has made that transition to laptops, and we can finally tell you whether it’s as big a game-changer in the portable market as it has already proven to be on the desktop.
On paper, the Acer Swift 3 is the ideal system for weighing up the relative pros and cons of the latest mobile CPUs. That’s because it’s one of the very few mobile rigs offered with both AMD Ryzen and Intel Core processors. Yes, variables remain, including the motherboard, but the really critical bits, such as the screen, chassis and battery, are shared by both variants, providing about as level a playing field as you’re ever going to get.
For the most part, it’s a resolutely middle-market offering in a 15.6-inch form factor. It’s powered here by the Ryzen 5 2500U. That’s the second tier in a fourstrong range of mobile Ryzen CPUs. The 2500U has the full complement of four cores and eight threads on the CPU side, but it loses a pair of compute units from its AMD Vega graphics core. Where the Ryzen 7 2700U gets 10 compute units, the 2500U makes do with five.
The 2500U is also 200MHz down on clock speed, with a base clock of 2GHz, and a maximum Boost clock of 3.6GHz. But overall, it’s a good introduction to Ryzen’s mobile chops. Elsewhere, the Swift 3 boasts a Full HD IPS display covered in Corning Gorilla Glass, and a 256GB M.2 SSD hooked up via SATA, rather than the powerful PCI Express interface. In terms of physical attributes, it’s a mid-sized aluminium affair, rather than a truly thin-andlight option, weighing 2.2kg and equipped with a 48Wh battery. That battery not only reveals the Swift’s mid-market positioning, it also makes it tricky to get a feel for how efficient AMD’s Ryzen processor is in a mobile implementation. A premium 15-inch portable, such as Dell’s XPS, offers roughly double the battery capacity, for instance. Making matters worse, we had problems getting our pre-production review sample up to full charge. In short, we couldn’t assess the unit’s battery life at all.
During testing, this laptop kicked out a fairly mixed bag of results, both in outright terms and that performance in the same test varied widely over the course of multiple runs. We extracted scores varying from 340 to over 500 for Cinebench in multithreaded mode, even with Windows Update turned off. The graphics performance of the AMD Vega 3D core was also patchy. Maybe the firmware needs a tweak, or the cooling hasn’t had that final polish.
The overall sense is that this isn’t Ryzen mobile at its best. That’s a pity, not only for this laptop — it’s a solid little unit, with a nice IPS panel, and a firm feel to its keyboard performance — but also for the Ryzen chip, which looks very promising. For now, we think Ryzen will give certain members of Intel’s latest eighth-gen mobile CPU range a very serious run for their money, but we’ll need to spend time with a better optimised system for a more detailed conclusion.
