Apple Silicon (Macs — the local-LLM favorite)

Apple’s CPU/GPU/Neural Engine share one pool of unified memory, so a Mac can hold an entire large model in RAM — no PCIe transfer bottleneck. That, plus high memory bandwidth and the excellent MLX framework, makes Macs the most popular hardware for serious local inference. The deciding spec is unified memory (how big a model fits) and bandwidth (how fast it decodes). All model picks lead with the newest releases (Aug 2026).


M4 family (2024–2025)

Spec M4 M4 Pro M4 Max
CPU 10-core 14-core (12/14 in late refresh) 16-core
GPU 10-core 20-core 40-core
Neural Engine 16-core 16-core 16-core
Memory up to 32 GB up to 64 GB up to 128 GB
Bandwidth ~120 GB/s ~273 GB/s ~546 GB/s
Devices MacBook Pro 14, iMac, Mac mini, iPad Pro MacBook Pro, Mac mini MacBook Pro, Mac Studio

Best for: Excellent local AI on a laptop; the 128 GB M4 Max MacBook Pro became the 2025 reference machine for running big models.

M5 (October 2025)

Spec Value
CPU 12-core (MacBook Pro/Air configs; 10-core in Air)
GPU 16-core (10-core in Air)
Neural Engine 16-core
Bandwidth ~153 GB/s (Air) up to ~250 GB/s (Pro)
Process TSMC N3 (2nd-gen)
Devices MacBook Pro 14, MacBook Air, iPad Pro
Price (Aug 2026) MacBook Air from $1,099 (up $100 from M4); MacBook Pro 14 from ~$1,599

Best for: The mainstream upgrade — Apple’s ML research measured 19–27% faster LLM throughput than M4 on the same workloads, driven by greater memory bandwidth.

M5 Pro / M5 Max (March 2026)

Spec M5 Pro M5 Max
CPU 15-core (5 super + 10 perf) or 18-core (6 super + 12 perf) 18-core
GPU 16-core or 20-core 40-core (each GPU core has a Neural Accelerator)
Neural Engine 16-core 16-core
Memory up to 48 GB (reported) up to 128 GB
Bandwidth ~256 GB/s class ~700 GB/s (~28% over M4 Max)
Devices MacBook Pro 14/16 MacBook Pro 14/16
Price (Aug 2026) 14″ from $2,199 (up $200 from M4); 16″ from $2,699 14″ from $3,599; 16″ from $3,899 (Amazon record lows to ~$1,984 for 24 GB M5 Pro)

Best for: The best laptop for local LLMs in 2026. Apple claims up to 4× faster LLM prompt processing than M4 Pro/Max and up to 8× AI image generation vs M1 Pro/Max.

M5 Ultra (Mac Studio, 2026)

Spec Value (reported)
CPU 36-core
GPU 84-core
Neural Engine 32-core
Memory up to 512 GB (768 GB per latest 2026 reports)
Bandwidth ~1 TB/s class (reported)
Storage up to 16 TB
Price from ~$4,000+ (reported)

Best for: The extreme end of local inference — the only mainstream desktop that holds the newest frontier open models entirely in memory.

Quick decision table

Mac Memory ceiling Newest picks that fit (Q4) 70B-class speed
M4/M5 (base) 24–32 GB Ministral 3 8B/14B, Qwen3.5, Gemma 4
M4 Pro / M5 Pro 48–64 GB Gemma 3 27B, GLM-4.7-Flash, Devstral 2 ~8–10 tok/s (Q3)
M4 Max 128 GB Mistral Medium 3, gpt-oss-120B 8–12 tok/s
M5 Max 128 GB Mistral Medium 3, gpt-oss-120B 12–16 tok/s
M5 Ultra (Studio) 512 GB+ MiniMax M2.5, Mistral Large 3, GLM-5.2 ~20–25 tok/s

Bottom line: Buy the most unified memory you can afford — it’s the single spec that decides which of the newest models you can run at all. Speeds are bandwidth-bound; MLX/llama.cpp/Ollama all work great.
