  • AMD Zen 6 CPUs Expected with Up to 96MB L3 Cache on Non-X3D Model

    AMD Zen 6 CPUs Expected with Up to 96MB L3 Cache on Non-X3D Model

    Key Takeaways

    1. The upcoming AMD Zen 6 processors may feature a high-end desktop variant with up to 24 CPU cores, surpassing the previous limit of 16 cores.
    2. AMD plans to increase the L3 cache per CCD to 48 MB, potentially resulting in up to 224 MB of L3 cache for a 24-core CPU with dual V-cache.
    3. A single CCD may house 16 Zen 6 cores, with configurations available for 32-core variants totaling 128 MB of L3 cache.
    4. Future laptop models might combine Zen 5 and Zen 6 CCDs, as suggested by the Strix Point development.
    5. The next-generation Epyc server processors are expected to benefit from the increased cache and new core configurations.

    Now that the AMD Zen 5 series is largely released, the whispers about the upcoming Zen 6 processors are becoming more common. Initially, it appears that the highest-end desktop variant (possibly named Ryzen 9 11,950X) will surpass the previous limit of 16 CPU cores. A previous leak hinted that this number might reach up to 24 cores. A recent report from Weibo provides further details on this topic.

    Increased Cache Capabilities

    AMD is set to boost the L3 cache per CCD to 48 MB. Therefore, a 24-core CPU utilizing 2 Zen 6 CCDs would feature a total of 96 MB of L3 cache. If a 64 MB 3D V-cache tile is added to one of the CCDs, this would result in 160 MB of L3 cache, and if both CCDs have one, that would be an impressive 224 MB. However, it’s still too early to make guesses about what the Zen 6 X3D will offer, though it would be a perfect opportunity to introduce a dual V-cache CPU for consumers.

    New Core Configurations

    Additionally, AMD intends to fit 16 Zen 6 cores within a single CCD, accompanied by 64 MB of L3 cache. There is a 32-core variant with 2 of these CCDs totaling 128 MB of L3 cache, though it remains unclear which lineup it belongs to. If Strix Point is indicative of future developments, some laptop models may feature a combination of Zen 5 and Zen 6 CCDs. Also, this configuration is expected to appear in the next-generation Epyc server processors, which will also gain from the increased cache.

  • AMD Ryzen AI 400 Medusa Point Laptop Chips to Feature RDNA 3 GPU

    AMD Ryzen AI 400 Medusa Point Laptop Chips to Feature RDNA 3 GPU

    Key Takeaways

    1. AMD’s Zen 6 series will be branded as Medusa, with Medusa Ridge for desktops and Medusa Point/Halo for portable devices.
    2. Medusa Point laptops will feature an unknown version of RDNA 3 iGPUs, likely RDNA 3.5, but will not upgrade to RDNA 4.
    3. The Video Core Next (VCN) for Medusa Point may also be limited, affecting performance compared to Nvidia and Intel GPUs.
    4. AMD has confirmed that RDNA 4 will be exclusive to desktop discrete GPUs, explaining the choice of RDNA 3.5 for Medusa Point.
    5. Medusa Halo might benefit from newer GPU technology, but there are concerns about reusing the RDNA 3.5 GPU from the previous Strix Halo generation.

    A recent leak suggests that AMD’s Zen 6 series will operate under the Medusa name, featuring Medusa Ridge for desktop processors and Medusa Point/Medusa Halo for portable devices. It would be logical to think that the new Zen 6 CPU cores would come with an updated RDNA integrated GPU (iGPU). However, according to a new leak from Weibo, this may not be true for laptops.

    Medusa Point’s iGPU Limitations

    Laptops under the Medusa Point label will apparently be using an unknown version of the RDNA 3 iGPUs, likely falling into the RDNA 3.5 category. Unfortunately, these devices won’t receive the highly sought-after RDNA 4 upgrade, which introduces hardware-based FSR 4.0 and other features that come with the new architecture. As a result, the Video Core Next (VCN) may also be limited to the older version, which could create issues as it lacks many of the advanced capabilities of its Nvidia and Intel counterparts.

    AMD’s Confirmation on RDNA Exclusivity

    In a prior statement, AMD made it clear that RDNA 4 would be reserved only for desktop discrete GPUs, so the choice to utilize RDNA 3.5 for Medusa Point isn’t particularly shocking. Meanwhile, RDNA 5 (or UDNA, depending on who you ask) is still planned for the desktop Ryzen 11,000 series components. This brings us to the eagerly anticipated Strix Halo successor—Medusa Halo. A newer generation GPU could significantly benefit from its additional memory bandwidth and the rumored 3D V-cache. It would be quite disappointing if AMD decides to reuse the Strix Halo’s RDNA 3.5 GPU for yet another generation.
