Why does Navi 24 cut the codec function? AMD employees refer to the use of Rembrandt APU on laptops

The Radeon RX 6500 XT graphics card that has just been unblocked has been criticized a lot, the lack of codecs, 4GB of video memory is likely to 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 problems have caused a lot of controversy, so that many gamers are frustrated. For a desktop graphics card priced at $199, a considerable number of gamers gave a more negative review. Moreover, if you want to buy this graphics card, the actual transaction price will most likely be higher than the suggested retail price. ATD once deleted articles in the community about the benefits of large-capacity video memory for games, which made people feel embarrassed by publicity.

Why does Navi 24 cut the codec function? AMD employees refer to the use of Rembrandt APU on laptops

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

According to a user named John Bridgman on the Phronix forum (AMD's Linux NPI software architect), the reason why AMD has drastically reduced the codec function on the Navi 24 core is that the main purpose of the Navi 24 is to use it on laptops with the APU codenamed Rembrandt. AMD's next-generation Ryzen 6000 series APUs, unveiled at CES 2022, features a Zen 3+ architecture core that supports USB 4, PCIe 4.0, and LPDDR5/DDR5 memory. Like the Navi 24, they are manufactured using the TSMC 6nm process. This series of APUs is configured with a kernel display of the RDNA 2 architecture with full codec function.

For John Bridgman, Navi 24 should only limit the encoding, the decoding part is complete, but it is not certain whether it is really cut in the end, or the information on the promotional page is wrong. If the design of the Navi 24 can be said to be on the mobile platform, it is embarrassing on the desktop platform. Nvidia should be happy, after all, the GeForce RTX 3050 is much better than the situation, and the GA107 core has not yet appeared on the desktop platform, and there is still a large room for operation in the entry-level product line in the future.
