AMD commercial reveals the benefits of RDNA 2 for consoles and PCs

Yesterday AMD unveiled the Radeon RX 6000 series graphics cards, and judging by the company’s statements, we can say that Turing and Ampere finally have worthy competitors. The company also unveiled a promotional video highlighting the RDNA 2 architecture that powers the latest graphics cards and both next-generation gaming consoles.

In this video, AMD refers to RDNA 2 as a breakthrough gaming architecture for PCs and consoles that has enabled a leap in performance and efficiency. First of all, the company mentions the 54% superiority of 7nm RDNA 2 in terms of performance per watt compared to 7nm RDNA. The latter, by the way, at one time also brought a similar 50% increase in relation to GCN.

The manufacturer also said that the computing units (CU) have been redesigned, allowing the operating frequencies to be increased by 30%. Each CU also now has its own hardware ray-tracing accelerator – AMD simply calls them Ray Accelerator (RA). RA allows you to speed up the rendering of ray intersections by an order of magnitude and provide real-time hybrid rendering effects based on DirectX Raytracing.

Finally, AMD also mentioned the new high-speed 128 MB Infinity Cache buffer, which significantly expands the effective memory bandwidth of new video cards and reduces power consumption. According to AMD estimates, a bundle of Infinity Cache with a 256-bit bus and 16 GB of GDDR6 memory provides an effective bandwidth of 1664 GB / s. For comparison: without Infinity Cache, the same bundle has a bandwidth of only 512 GB / s, that is, 3.25 times less.

By the way, to date, the most impressive demonstration of the capabilities of the new generation of games was performed on RDNA 2 (albeit in the PlayStation 5 version). We are talking about the Lumen in the Land of Nanite tech-demo, shown in March, based on Unreal Engine 5 with the technology of “infinite” geometry, fully dynamic global illumination, and so on:
