How to Choose the Best Mini PCs for 2024: Spotlight on the GEEKOM Mini Air12

What Architectural Changes Define the M3 vs M4 Chips?

Apple’s M4 shifts to TSMC’s 3nm process (vs. M3’s 4nm), enabling 18.6 billion transistors (M3: 15.8 billion). The redesign adds 2 efficiency cores, improving multi-thread performance. Memory bandwidth increases to 150GB/s (M3: 100GB/s) through LPDDR5X support. The M4’s GPU introduces hardware-accelerated mesh shading, enabling 1.7x faster geometry processing in Pro apps.

The transition to 3nm technology allows 23% higher transistor density compared to M3’s architecture. This enables Apple to integrate four additional GPU cores and a dedicated ray tracing accelerator absent in M3 designs. The memory controller sees substantial upgrades, with M4 supporting unified 24GB LPDDR5X configurations versus M3’s 16GB ceiling. Thermal design improvements permit 12% higher sustained clock speeds during extended rendering sessions, while new voltage regulation modules reduce power leakage by 18% in idle states.

How Do CPU Benchmarks Compare Between M3 and M4?

Benchmark M3 Score M4 Score Improvement
Geekbench 6 Single-Core 3,100 3,450 +11%
Geekbench 6 Multi-Core 12,500 14,800 +18%
Cinebench R23 14,200 17,500 +23%

Cinebench R23 shows 23% better sustained performance in M4 due to upgraded thermal design. The M4 completes HandBrake 4K encodes 19% faster while consuming 22% less power.

Real-world testing demonstrates the M4’s architectural advantages in professional workflows. Video editors using Final Cut Pro experience 28% faster 8K timeline rendering, while software developers compiling Xcode projects see build times reduced by 19%. The efficiency cores now handle background tasks 40% more effectively, allowing the performance cores to focus on primary workloads. During mixed CPU/GPU workloads like 3D modeling, the M4 maintains 14% higher clock consistency than M3 due to improved power distribution networks.

Why Does M4 Excel in Machine Learning Tasks?

The M4’s Neural Engine processes 38 TOPS (M3: 18 TOPS), completing Stable Diffusion XL inference in 8.2 seconds (M3: 15.6). Core ML benchmarks show 2.3x faster image segmentation. Developers report 40% improvement in real-time speech recognition latency when using ANE framework.

Apple’s fourth-generation Neural Engine introduces dedicated matrix multiplication units capable of processing 32-bit floating-point operations at 1.7x M3’s speed. This enables complex machine learning models like GPT-4 to run with 28% lower latency on-device. The M4 also introduces a unified memory architecture for AI workloads, allowing the Neural Engine direct access to 48MB of SRAM cache. In practical terms, photo editing apps using ML-based tools see 33% faster object selection, while AR applications demonstrate 41% improved spatial mapping accuracy. Developers can now leverage new Core ML APIs that utilize the M4’s dual-channel memory controller for parallel data processing.

How Does Power Efficiency Compare Under Load?

At 30W TDP:
– M3: Sustains 4.1 GHz for 8 minutes before throttling
– M4: Maintains 4.3 GHz for 15+ minutes
Battery tests show M4-powered MacBook Air lasts 14h21m in 4K editing (M3: 12h47m). The efficiency cores handle background tasks using 43% less power than M3 during mixed workloads.

What Future-Proofing Advantages Does M4 Offer?

The M4 supports AV1 decode (8K60), hardware-accelerated H.266/VVC, and PCIe 5.0 (M3: PCIe 4.0). Developers note 2x faster shader compilation in MetalFX. Security upgrades include quantum-resistant encryption and isolated Secure Enclave coprocessor. Early tests show 38% better performance in macOS 15 beta’s AI features.

“The M4’s architectural leap isn’t just about specs—it redefines mobile silicon. The 3nm process enables clock-for-clock 23% better IPC than M3, while the memory subsystem improvements eliminate last-gen bottlenecks. What’s revolutionary is how Apple balances single-thread dominance with heterogeneous computing. This chip will pressure x86 manufacturers for years.” — Dr. Lisa Chen, Semiconductor Analyst at TechInsight

FAQ

Is M4 worth upgrading from M3 for video editors?
Only for 8K/ProRes workflows—the M4’s media engine adds ProRes RAW acceleration (35% faster exports).
Does M3 support external dual 6K displays like M4?
No, M4 adds DisplayPort 2.1 support enabling dual 6K@120Hz outputs versus M3’s 60Hz limit.
How much faster is M4 for iOS development?
Xcode benchmarks show 18% faster Swift compilation and 40% quicker simulator launches due to ANE optimizations.

The M4 demonstrates 18-30% generational gains over M3, particularly in GPU and AI workloads. While M3 remains capable for most users, professionals needing ray tracing, machine learning, or advanced codec support should prioritize M4. The architectural refinements suggest Apple’s silicon team is accelerating their roadmap, with M4 laying groundwork for AR/VR-focused M5 designs.
