Editor’s take: The brand new Radeon RX 6800M GPU in Asus’s Strix G15 appears to undergo critical efficiency deficits with its inventory RAM, in addition to when outputting to its inner show. Each of those will be fastened comparatively simply, but it surely’s not a very good begin for the hardware-focused AMD Benefit initiative.
When is a GPU not that very same GPU? When it is in a laptop computer!
Gaming laptop computer consumers are long-used to purchasing weaker variations of the graphics playing cards offered beneath the identical identify within the desktop house, with decrease TDPs and fewer cores (even when not supposed!)—however in addition to these two components, AMD’s RX 6800M appears to be being tripped up by the remainder of the laptop computer it is available in.
With the Asus ROG Strix G15 in evaluate, YouTuber JarrodsTech discovered that the laptop computer had critical efficiency losses when utilizing inventory RAM and the laptop computer’s personal inner show in use. The ROG G15, like many different gaming laptops, incorporates hybrid graphics switching between the discrete GPU and the CPU’s built-in graphics; this improves battery life however constrains bandwidth and eats into the CPU’s energy finances.
Nvidia’s Superior Optimus can power a discrete-graphics-only mode, however the G15 has no such choice, which means that it solely reaches most efficiency when outputting to an exterior show. Moreover, the free timings of the manufacturer-provided reminiscence additionally harm efficiency additional—beforehand additionally seen within the Ryzen-powered Lenovo Legion 5 Professional—and the impact of those two components is reasonably stunning when put collectively.

Changing the RAM and outputting to an inner show noticed the G15 leap from an 102 to 135 FPS common in Shadow of the Tomb Raider; in relative phrases, the 6800M was being held again to barely RTX 3060-beating efficiency when it could possibly be buying and selling blows with a high-powered RTX 3080.
This presents a critical situation for would-be consumers. Our evaluate of the Radeon 6800M right here at TechSpot used the identical Asus laptop computer and we took word of the problem of reminiscence timings — we truly changed it so as to benchmark the GPU apples-to-apples as we normally do — and ran exams with each inner and exterior show output, however many others will not have, resulting in shoppers merely seeing an AMD-only unit underperforming in comparison with its Intel and Nvidia rivals when in actuality it is being constrained by poor selections on the producer’s half.
Seeing the G15 with these points is a very dangerous search for the purple crew, because it’s purported to be the debut of the AMD Benefit initiative, a set of targets set by AMD for laptops when working with producers akin to these of Nvidia Max-Q or Intel Evo.
Asus’s latest shut partnership with AMD—bringing Ryzen CPUs to the ROG Zephyrus G14 and Stream X13 ultraportables and even going to the engineering effort of utilizing liquid metallic thermal paste on them—makes these design gaffes much more baffling.
And whereas not one of the Benefit necessities explicitly cowl RAM, graphics switching and even efficiency as a complete, the initiative is meant to be AMD working with their companions to get the very best out of the methods their chips go into—and having poor implementation choking these chips two tiers down the product stack is hardly placing their greatest foot ahead.
