AMD Ryzen AI 5 340

The AMD Ryzen AI 5 340 is a modern mid-range mobile processor designed for thin-and-light laptops and AI-enhanced computing. It integrates CPU, GPU, and a dedicated Neural Processing Unit (NPU) on a single chip, enabling efficient performance across productivity, graphics, and AI workloads.

Architecture & Fabrication

• Architecture: Hybrid design (performance + efficiency cores)
• Cores / Threads: 6 cores, up to 12 threads
• Fabrication Process: TSMC 4nm (N4)
• Manufacturer: Taiwan Semiconductor Manufacturing Company (TSMC)

The 4nm process is among the most advanced nodes currently used for laptop processors (2025–2026). Compared to older 7nm chips, it provides significantly higher transistor density, lower power leakage, and improved performance-per-watt.

Comparison to Previous Generation

• Ryzen 5000 series (e.g., 5600H) used TSMC 7nm
• ~1.7x higher transistor density with 4nm
• ~15–25% better efficiency
• Lower thermals and better sustained performance

Cache & Memory

• L2 Cache: ~6 MB
• L3 Cache: ~16 MB
• Total Cache: ~22 MB
• Memory Support: DDR5-5600, LPDDR5/LPDDR5X (up to ~7500 MT/s)

Clock Speeds & Performance

• Base Clock: ~3.0–3.5 GHz
• Boost Clock: Up to ~4.5–4.7 GHz

Performance is comparable to Intel Core Ultra 5 and newer Ryzen 5 mobile chips depending on power limits.

Performance Improvements (vs Ryzen 5 5600H)

• ~20–30% higher single-core performance
• ~25–40% better multi-core efficiency
• Better battery life
• AI tasks offloaded to NPU

Integrated Graphics

• Architecture: RDNA 3 Radeon Graphics
• Compute Units: ~6–8 CUs
• Frequency: Up to ~2.5 GHz

Up to ~2x faster than older Vega graphics with improved media support (including AV1).

AI Engine (NPU)

• Dedicated AI Engine: Yes
• Performance: ~10–15 TOPS

Handles AI tasks like background blur, noise suppression, and local AI inference.

Power Consumption

• Configurable TDP: ~28W to 45W

Efficient due to 4nm process and hybrid design.

Summary

• 4nm TSMC process
• 6-core hybrid CPU
• Up to ~4.7 GHz
• ~22 MB cache
• RDNA 3 graphics
• Dedicated AI engine
• DDR5 / LPDDR5X support
• 28W–45W TDP

Overall: A major upgrade over Ryzen 5000 series with better efficiency, stronger graphics, and built-in AI capabilities.
