Summary

TLDRIn this tech review, the AMD Ryzen 9 7950X 3D processor is put through its paces, showcasing its impressive performance with 3D V-Cache technology. Despite its high cost and complex software requirements for optimal performance, the processor delivers significant gains in gaming and productivity tasks, outperforming its non-3D counterpart and setting a new standard for efficiency with low power draw under load. However, the high idle power consumption and the necessity for a specific BIOS and drivers installation for the 3D cache to function correctly are noted concerns.

Takeaways

  • 🚀 AMD has announced the Ryzen 9, 7950X 3D processor with 3D V-Cache technology, promising significant performance improvements in certain applications and games.
  • 📅 The Ryzen 9, 7950X 3D is set to launch in February, but the 8-core Ryzen 7 will be available later in April.
  • 💡 The 3D V-Cache technology in the Ryzen 9, 7950X 3D allows for asymmetric cache configurations, which AMD will manage through software with the AMD 3D V-Cache Performance Optimizer driver.
  • 🔍 AMD presented charts showing the 7950X 3D outperforming the Intel Core i9 3900K and the regular Ryzen 9 7950X in various gaming benchmarks, though the choice of games was controlled by AMD.
  • 💰 The 7950X 3D is priced similarly to the non-3D 7950X, which had a price reduction since its launch, making it a competitive option for high-performance processors.
  • 🛠️ The Ryzen 7000 series and AM5 motherboards require a specific BIOS and chipset driver to support the 3D V-Cache technology, indicating a complex setup process.
  • 🔥 The Ryzen 9, 7950X 3D showed lower power consumption and cooler temperatures under load compared to the non-3D version, which is impressive for performance-oriented processors.
  • 🎮 In gaming tests, the 3D cache provided a noticeable boost in frame rates, with some games showing as much as a 30-40% improvement.
  • 🤔 The reviewer expressed skepticism about the consistency of the performance gains across different games and the complexity of the required software stack for the 3D cache to function correctly.
  • ⏰ The Ryzen 7 7800X 3D, which is expected to be a strong contender for gaming performance, has not been reviewed yet, suggesting potential future competition for the 7950X 3D.
  • 🏆 Despite some concerns, the Ryzen 9, 7950X 3D received a high rating of 9 out of 10, being deemed a 'must-have' for those seeking top-tier performance.

Q & A

  • What new product was announced by AMD during the keynote?

    -AMD announced the Ryzen 9 7950X 3D, which is a processor with 3D V-Cache technology, along with other Zen 4 models featuring 3D cache, including the Ryzen 7 and Ryzen 9 series.

  • When are the new Ryzen 7000 processors expected to launch?

    -The new Ryzen 7000 processors, specifically the 7800, 7900, and 7950X 3D parts, were announced to launch in February, with the 8-core Ryzen 7 going on sale in April.

  • What is the AMD 3D V-Cache Performance Optimizer and how does it work?

    -The AMD 3D V-Cache Performance Optimizer is a driver that, along with the AMD PPM Provisioning File driver, detects when a game is being played and ideally directs it to run on the core complex with the extra 3D cache for performance benefits.

  • How does AMD's 3D V-Cache differ from Intel's Alder Lake and Raptor Lake hybrid core technology?

    -While Intel's Alder Lake and Raptor Lake designs include a mix of performance and efficient cores with extra hardware support from the start, AMD is adding 3D V-Cache to an existing processor design, managing the asymmetric cache configuration through software.

  • What potential performance benefits were shown by AMD for the Ryzen 9 7950X 3D?

    -AMD presented charts indicating that the Ryzen 9 7950X 3D could show significant performance gains over the Intel Core i9 3900K and the regular Ryzen 9 7950X in certain games, with only minor losses in others.

  • Why might AMD choose to stack cache or memory in their processor designs?

    -Stacking cache or memory can shorten connection lengths, reduce costs associated with monolithic die size, and improve scalability on a given fabrication process. It also allows for more efficient thermal management and power delivery.

  • What is the significance of the 3D cache technology for AMD's future processor designs?

    -The 3D cache technology is significant as it represents a step towards more advanced stacking techniques, which could include stacking regular DRAM, and even graphics, potentially leading to more powerful and efficient processors.

  • What steps are required to ensure the Ryzen 9 7950X 3D's 3D V-Cache is functioning correctly?

    -Several steps are needed, including installing the correct BIOS version, ensuring the AMD 3D V-Cache Performance Optimizer driver and AMD PPM Provisioning File driver are installed, verifying the AMD 3D V-Cache device in Device Manager, and checking that the Xbox Game Bar and related services are up to date.

  • How did the Ryzen 9 7950X 3D perform in gaming benchmarks compared to the regular Ryzen 9 7950X and Intel Core i9 13900K?

    -The Ryzen 9 7950X 3D showed significant performance improvements in gaming benchmarks, often outperforming both the regular Ryzen 9 7950X and the Intel Core i9 13900K, with higher frame rates in games like Far Cry 6 and Borderlands 3.

  • What are some of the potential downsides or concerns regarding the Ryzen 9 7950X 3D processor?

    -Some concerns include the high cost of the CPU and motherboard, the complexity of the required software stack for the 3D V-Cache to function correctly, high idle power draw, and the lack of direct comparison to the yet-to-be-released Ryzen 7 7800X 3D.
