For those looking for a budget desktop PC capable of handling gaming and AI tasks, the recently launched AMD Ryzen 8000G series is worth considering. These processors, based on Zen 4 APUs with RDNA3 graphics, offer impressive performance and features within their price range. Let’s dive into the details of the two available models: the Ryzen 7 8700G and the Ryzen 5 8600G.

Ryzen 7 8700G: Flagship Power

  • The Ryzen 7 8700G is the flagship of the series, equipped with eight Zen 4 cores (8C/16T) that can boost up to an impressive 5.1 GHz, running at a base frequency of 4.2 GHz.
  • It features Radeon 780M graphics from AMD based on the RDNA3 architecture, with 12 CUs and 768 shader units clocked at 2.9 GHz.
  • This APU is a powerhouse, capable of handling most AAA games at high settings and resolutions, while offering a Smooth performance in creative and productivity applications.

Ryzen 5 8600G: Balanced Performance

  • The Ryzen 5 8600G, although a little cheaper, still packs plenty of power with six Zen 4 cores (6C/12T) that reach a maximum turbo frequency of 5.0 GHz and a base frequency of 4.3 GHz.
  • It features Integrated Radeon 760M RDNA3 graphics, equipped with 8 CUs and 512 shading units clocked at 2.8 GHz.
  • Ideal for casual gamers and users looking for a reliable PC for daily tasks and entertainment.

Efficiency and Compatibility

  • Both APUs are built on AMD’s Phoenix-based mobile architecture, ensuring low power consumption and high efficiency.
  • They are designed to fit inside the AM5 desktop socket, compatible with DDR5 memory and PCIe Gen 5.0 interface.
  • The Ryzen 8000G series also introduces AMD’s Ryzen AI NPU to the desktop market for the first time, offering a dedicated processor for AI inference and machine learning applications.

Zen 4 Microarchitecture: A Technological Leap

  • The Ryzen 8000G series adopts the Zen 4 microarchitecture, marking a significant leap in AMD’s CPU design.
  • Zen 4 brings several improvements over Zen 3, including higher clock speeds, larger cache sizes, improved IPC (instructions per cycle), improved security features, and support for cutting-edge technologies such as DDR5 and PCIe Gen 5.
  • With Zen 4, AMD increases the core count from four to eight in its APUs, providing a substantial advantage over competitors.

Security Features – Protecting Your System

Zen 4 introduces several security features, including:

  • Secure Encrypted Virtualization (SEV):
    • An extension of AMD’s memory encryption technology, SEV protects data from unauthorized access by encrypting it at the hardware level.
    • SEV allows users to create multiple encrypted virtual machines (VMs) on a single physical processor, ensuring data security and isolation.
  • Shadow Stack:
    • A hardware-based mechanism to prevent return-oriented programming (ROP) attacks.
    • ROP attacks manipulate the stack pointer to execute malicious code that is already present in memory.
    • Shadow Stack creates a protected copy of the original stack pointer, making it impossible for attackers to hijack the control flow of a program.

Affordability and Availability

The Ryzen 8000G series offers a cost-effective solution for building a powerful desktop PC without the need for a discrete graphics card. Priced at $329 for the Ryzen 7 8700G and $229 for the Ryzen 5 8600G, these APUs provide a cheaper alternative compared to purchasing a separate CPU and GPU combo. Scheduled for release in the second quarter of 2024, users can expect to enjoy high-performance computing at an affordable price. Stay tuned for updates and reviews as the release date approaches.
