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 inside show. Each of those will be mounted comparatively simply, but it surely’s not a superb 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 patrons are long-used to purchasing weaker variations of the graphics playing cards offered below the identical title within the desktop house, with decrease TDPs and fewer cores (even when not supposed!)—however in addition to these two elements, 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 assessment, YouTuber JarrodsTech discovered that the laptop computer had critical efficiency losses when utilizing inventory RAM and the laptop computer’s personal inside 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 pressure 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 unfastened timings of the manufacturer-provided reminiscence additionally damage efficiency additional—beforehand additionally seen within the Ryzen-powered Lenovo Legion 5 Professional—and the impact of those two elements is reasonably stunning when put collectively.

Changing the RAM and outputting to an inside show noticed the G15 bounce 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 might be buying and selling blows with a high-powered RTX 3080.
This presents a critical subject for would-be patrons. Our assessment of the Radeon 6800M right here at TechSpot used the identical Asus laptop computer and we took be aware of the difficulty of reminiscence timings — we really changed it so as to benchmark the GPU apples-to-apples as we normally do — and ran exams with each inside and exterior show output, however many others will not have, resulting in customers merely seeing an AMD-only unit underperforming in comparison with its Intel and Nvidia rivals when in actuality it is being constrained by poor choices on the producer’s half.
Seeing the G15 with these points is a very unhealthy search for the purple staff, because it’s imagined 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 Circulate 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 perfect out of the programs their chips go into—and having poor implementation choking these chips two tiers down the product stack is hardly placing their finest foot ahead.
