AMD 4800S
AMD 4800S: A Comprehensive Overview of the Enthusiast Processor
Codename: Ariel, 7 nm, 8 cores, and a focus on efficiency
Key Features: Architecture and Performance
The AMD 4800S processor, known by its codename Ariel, is built on the Zen 2 architecture and manufactured using a 7-nm process. This is an 8-core chip with 16 threads, providing excellent multitasking capabilities. The L3 cache is 8 MB, and the TDP is just 65 W, which sets it apart from competitors with similar performance.
Key Features:
- Energy Efficiency: With a TDP of 65 W, the processor delivers impressive performance in multithreaded tasks. For example, in Geekbench 6, it scores 1457 points in single-threaded and 8323 in multithreaded tests, closely matching the performance of the Ryzen 7 3700X.
- PCIe 4.0 Support: Despite being based on Zen 2, the chip supports modern interfaces, ideal for NVMe drives and graphics cards.
- Optimization for OEM Solutions: Originally designed for Microsoft Xbox Series X/S but adapted for PCs, which explains its specific integration.
Practical Example: In a build with an NVIDIA RTX 3060 Ti, the processor rendered 4K video in DaVinci Resolve 20% faster than the Intel i5-11400F, thanks to its 16 threads.
Compatible Motherboards: Choosing Nuances
The AMD 4800S uses the FP6 socket, traditionally employed in mobile solutions. This imposes certain limitations:
- OEM Motherboards: The processor is often delivered as part of complete systems (like mini PCs or specialized workstations) with Mini-ITX motherboards.
- Chipsets: Supports solutions based on Promontory LP (similar to A520), but it's challenging to find retail motherboards.
- Advice: If building a system from scratch, look for "CPU + motherboard" bundles from suppliers like ASRock Industrial or Simply NUC.
Supported Memory: DDR4 Takes Priority
The processor operates with DDR4-3200 (in dual-channel mode). DDR5 support is absent, which is expected for the Zen 2 architecture.
Recommendations:
- Choose modules with low timings (CL16 or lower) to maximize performance.
- An optimal capacity is 32 GB (2×16 GB): sufficient for gaming, editing, and virtualization.
Example: In tests with Kingston Fury DDR4-3200 CL16 RAM, latency in games was reduced by 8% compared to budget modules.
Power Supplies: Power Calculation
With a TDP of 65 W, the processor is not demanding in terms of power, but it's essential to account for other components:
- Minimum PSU Power: For a system with a graphics card like the RTX 3060 (170 W), 550 W (e.g., Corsair CX550) is sufficient.
- Headroom: If planning an upgrade, choose power supplies in the 650–750 W range (Seasonic Focus GX-650).
- Certification: 80+ Bronze or higher will ensure stability and efficiency.
Pros and Cons of the AMD 4800S
Advantages:
1. Energy Efficiency: Ideal for compact builds and systems with passive cooling.
2. Multithreaded Power: 16 threads handle rendering, streaming, and heavy workloads effectively.
3. PCIe 4.0: Future-proof solution for SSDs and GPUs.
Disadvantages:
1. Limited Compatibility: Challenges in finding a compatible motherboard.
2. No Integrated Graphics: Requires a discrete graphics card.
3. Zen 2 Architecture: Lagging behind Zen 3 in single-threaded tasks (e.g., Ryzen 7 5800X is 15% faster in games).
Use Cases: Where the Potential is Unleashed
1. Gaming: Paired with an RTX 3070 in Cyberpunk 2077 (1080p, Ultra) — stable 60+ FPS.
2. Work Tasks: Virtualization, code compilation, 3D modeling.
3. Multimedia: Streaming in OBS without lagging, facilitated by 16 threads.
Real Case: A freelance designer uses the 4800S with an RTX 3060 and 32 GB RAM for work in Blender and Adobe Premiere. Rendering a 1-hour project was reduced to 40 minutes.
Comparisons with Competitors
- AMD Ryzen 7 3700X: Close in performance but with a TDP of 65 W versus 105 W for the 3700X. However, the 3700X is easier to integrate (AM4, DDR4).
- Intel Core i7-11700K: Higher single-thread speed (Geekbench 6 ~1600), but with a TDP of 125 W and heat concerns.
- Conclusion: The 4800S excels in energy efficiency but falls short in accessibility and build flexibility.
Practical Assembly Tips
1. Cooling: A decent tower cooler (e.g., Deepcool GAMMAXX 400) is sufficient — temperatures under load should not exceed 75°C.
2. Case: Choose models with good ventilation (Fractal Design Meshify C).
3. Memory: DDR4-3200 CL16, dual-channel mode.
4. Graphics Card: For gaming — RTX 3060 Ti or RX 6700 XT; for work — Quadro RTX 4000.
Final Verdict: Who is the AMD 4800S for?
This processor is the choice for:
- Enthusiasts of Compact Systems: Mini PCs, HTPCs, media centers.
- Professionals: Editors, developers, engineers seeking a balance between power and energy consumption.
- Overclocking Experimenters: Despite its limitations, the chip is intriguing for unconventional builds.
Why Choose It? The low TDP, 16 threads, and PCIe 4.0 support make the 4800S a unique solution in the niche of energy-efficient high-performance systems. However, be prepared for the search for compatible components and the absence of straightforward upgrades.
