architecture. More information about RDNA 2 was made public on AMD's Financial Analyst Day on March 5, 2020. AMD claimed that it would provide a 50% performance-per-watt improvement over RDNA, with increases in clock speed and instructions-per-clock. Additional features confirmed by AMD include real-time, hardware accelerated ray tracing, "Infinity Cache", mesh shaders, sampler feedback and variable rate shading. The company announced that RDNA 2 would be used in next-generation gaming consoles and PC graphics cards code-named "Navi 2X" and also nicknamed as "Big Navi". AMD unveiled the Radeon RX 6000 series, its next-gen RDNA 2 graphics cards at an online event on October 28, 2020. The lineup initially consisted of the RX 6800, RX 6800 XT and RX 6900 XT. The RX 6800 and 6800 XT launched on November 18, 2020, with the RX 6900 XT being released on December 8, 2020. Further variants including a Radeon RX 6700 (XT) series based on Navi 22, later launched on March 18, 2021. On May 31, 2021, AMD launched the RX 6000M series of GPUs designed for laptops. These include the RX 6600M, RX 6700M, and RX 6800M. These were made available beginning on June 1, 2021. On June 1, 2021, AMD's CEO Dr. Lisa Su and Tesla, Inc.'s CEO Elon Musk confirmed that the entertainment systems of Tesla's new Model S and Model X are powered by RDNA 2. The same microarchitecture was also announced to be used for an upcoming flagship Samsung Exynos SoC, later introduced in January 2022 as Exynos 2200, utilizing a custom Xclipse 920 GPU with 3 compute units. An RDNA 2 integrated GPU with 2 compute units is included in the I/O die on AMD's Zen 4-based Ryzen 7000 Series CPUs. According to AMD, the integrated RDNA 2 graphics in Ryzen 7000 are not intended for gaming and is instead intended for diagnostic purposes and offering video encode and decode capabilities.
