The primary use of Navi 24 will be in laptops paired with a Rembrandt APU

The Radeon RX 6500 XT graphics card that has just been released has been criticized a lot. The lack of codec, 4GB of video memory may not meet the needs of the game, and the PCIe 4.0 x4 interface has a large performance loss on the PCIe 3.0 platform. These issues have sparked a lot of controversies and frustrated many gamers. For a desktop graphics card priced at $199, a considerable number of gamers gave relatively negative comments. What’s more, if you want to buy this graphics card, the actual transaction price will likely be higher than the suggested retail price.

Radeon RX 6500XT PCIe 4.0

Recently, AMD released several Radeon PRO W6000 series workstation graphics cards with Navi 24 cores, including the Radeon Pro W6400 for desktop platforms, and the Radeon Pro W6500M and W6300M ​​for mobile platforms. It is understood that all graphics cards based on the Navi 24 core should lack 4K H.264/H.265 encoding and AV1 decoding.

According to a user named John Bridgman (AMD’s Linux NPI software architect) on the Phoronix forums, the reason why AMD greatly reduced the codec function on the Navi 24 core, “the primary use of Navi24 will be in laptops paired with a Rembrandt APU, which has full video functionality and Gen4 PCIE.” The new generation of Ryzen 6000 series APUs released by AMD at CES 2022 uses Zen 3+ architecture cores and supports USB 4, PCIe 4.0, and LPDDR5/DDR5 memory at the same time. Like the Navi 24, it is manufactured using TSMC’s 6nm process. This series of APUs is equipped with a core of the RDNA 2 architecture and has full codec functions.

John Bridgman pointed out “that was limited in Navi24, not decode – still not sure if that limitation is real or just a typo on the product page. Trying to find out a definitive answer.”
