    Radeon RX 9000 GPUs Support UEFI Systems Only, AMD Confirms

    Key Takeaways

    1. The Radeon RX 9000 series GPUs require UEFI BIOS for optimal performance and features.
    2. Older systems using Compatibility Support Module (CSM) may face limitations that hinder GPU potential.
    3. UEFI offers advantages like support for larger hard drives, NVMe SSD booting, faster boot times, and enhanced security.
    4. Users should disable CSM in BIOS/UEFI settings to fully utilize the RX 9000 series features.
    5. While the GPUs will function with CSM, performance and support levels will be suboptimal compared to using UEFI.

    AMD has announced that its new Radeon RX 9000 series GPUs, which are designed using the RDNA 4 architecture, are meant to work exclusively with UEFI BIOS. While many computers today use UEFI, some older models still operate on Compatibility Support Module (CSM) mode, which has significant restrictions. These restrictions prevent the Radeon RX 9000 series GPUs from reaching their full potential.

    Understanding UEFI vs. Legacy BIOS

    According to AMD’s support page, UEFI firmware is essential for modern PCs, and it has replaced the older BIOS standard. Although the terms are often confused, the difference is important. For the new RX 9000 series graphics cards, older systems that rely on CSM will miss out on advanced features like Smart Access Memory (Resizable BAR), which are designed to boost performance and efficiency.

    Benefits of UEFI for Gaming

    Thus, systems that utilize UEFI will be the only ones capable of maximizing these technologies, ensuring a superior gaming experience alongside the Radeon RX 9000 series GPUs. UEFI also allows for larger hard drives over 2.2TB, NVMe SSD booting, quicker start-up and shutdown times, and better security, among other advantages.

    AMD advises users to disable CSM in the BIOS or UEFI settings, typically located under the Boot tab. However, the exact steps can vary depending on the motherboard brand.

    Compatibility with Legacy Modes

    It’s important to note that the Radeon RX 9000 series GPUs aren’t incompatible with CSM or legacy modes. They will still start up normally and run games, but users may not achieve the promised performance levels or support that come with using UEFI.

  • AMD FSR 4 and RX 9070 Enhance Compatibility with FSR 3.1 Games

    AMD FSR 4 and RX 9070 Enhance Compatibility with FSR 3.1 Games

    Recently, news has spread among gamers that the Radeon RX 9070 and RX 9070 XT are now set for a March release. While this may be a wait, those who enjoy AMD graphics can look forward to FSR 4 being compatible with the currently supported FSR 3.1 games. FSR 4 represents AMD’s newest AI-driven upscaling technology that enhances framerates while maintaining image quality. The well-known leaker Kepler_L2 has assured that the upgrade process should be easy for both AMD and its users.

    FSR 4 Exclusivity

    It’s important to note that unlike FSR 3.1, FSR 4 will only work with AMD GPUs built on the RDNA 4 architecture. This means that gamers will have to be patient and await the RX 9000 series to experience the latest advancements in upscaling. Nevertheless, PCGamingWiki has listed many games compatible with FSR 3.1 that could readily take advantage of these upgrades. According to Kepler_L2, the upgrade process is simple and requires just a swap of an older AMD driver file with a new FSR 4 DLL.

    AMD’s Future Plans

    The expectation that FSR 4 would improve upon FSR 3.1 isn’t shocking, especially after AMD’s CES 2025 presentation. When comparing it to Nvidia’s DLSS 4 demonstration, the details about how FSR 4 will enhance gaming performance were somewhat vague. Nonetheless, the updated upscaler is designed to work together with frame generation to boost framerates. Additionally, AMD Anti-LAG 2 is expected to decrease latency, which often follows upscaling. Toward the end of the CES preview slide, AMD indicated that FSR 4 will necessitate that games already support FSR 3.1.

    Implications of Delay

    The unexpected delay of the RX 9000 series provides AMD with additional time to fine-tune games. Recently, well-known titles such as The Last of Us Part 1 have received patches for FSR 3.1 support. Some gamers remain doubtful that FSR 4 will mark a significant advancement in upscaling technology, making the pricing and raw performance of AMD’s upcoming GPUs crucial factors to consider.
