As the launch of the Radeon RX 6000 approaches and their ray tracing performance is expected to be lower than that of Nvidia’s RTX 3000, AMD is still working on its own alternative to DLSS. An alternative that would unfortunately only come long after the launch of the new graphics cards from Lisa Su’s firm.
Announced on October 28, the Radeon RX 6000 is, for the first time in years, a real response from AMD to Nvidia on the high end. But if the performance of its chips under RDNA2 architecture seems convincing to play comfortably in 4K, their performance in terms of ray tracing would place them between the RTX 2000 “Turing” (launched in 2018 by Nvidia) and the RTX 3000 “Ampere” (including the launch began last September).
Half a generation of delay that AMD seeks to reduce by working on a version of its own of DLSS. Only here, this technology of super sampling designed in-house by AMD (for the moment called “Super Resolution” and integrated into the FidelityFX suite) will not be ready for the launch of the new Radeons. Why ? Because AMD wants its technology to be open and multiplatform, in particular to make it fully compatible with new generation consoles equipped with SoCs based in part on the RDNA2 design.
AMD competitive even without its own DLSS?
« [AMD] promises that its supersampling technology will be open and cross-platform, which means it could arrive on next-gen consoles like the Xbox Series X and PS5. The company is working with a number of partners on this technology and expects significant industry support. Unfortunately, it will not be ready for the launch of these three new Radeon RX 6000 Series cards. “, In particular summed up Tom Warren (journalist of The Verge) after speaking with AMD executives.
It remains to be seen what the Radeon RX 6000 will be able to do in ray tracing against the RTX 3000, without DLSS equivalent. First two benchmarks on the run give us a first idea, even if this information should be taken with a grain of salt.

As it stands, the RX 6800 (the most affordable model announced last week by AMD) would be only 5% slower than an RTX 3070 at 1440p with ray tracing active (and DLSS active on the 3070) on Shadow of The Tomb Raider. The difference between the two cards would on the other hand be much more palpable under the same conditions, but this time in 4K, with between 15 and 20% more performance for the new chip from Nvidia.
Interestingly, the Radeon RX 6800 would be ahead of the RTX 3070 when the latter has DLSS removed.
As pointed out PC GamerHowever, these clues should be taken with care. The implementation of ray tracing in Shadow of The Tomb Raider is indeed quite limited. AMD had also announced that its RX 6800s will have an advantage in rasterization (traditional rendering) over the title of Crystal Dyamic against the RTX 3070. All these elements raise doubts about the universality of these results.
As a reminder, the Radeon RX 6900 and 6900XT will hit the market on November 18th.
