M4 Pro vs Base M4: What You Get
CPU & GPU Power
The M4 Pro adds 4 additional CPU cores (12-core vs 8-core) and increases GPU cores to 16 (from 10). In real-world terms: faster video rendering, better 3D performance, smoother large-document editing in Creative Suite.
Thunderbolt 5 Advantage
M4 Pro includes Thunderbolt 5 (vs TB4 on base M4). TB5 doubles bandwidth to 80 Gbps—useful for:
- High-speed external SSD farms (RAID arrays)
- Professional EGPU setups (though Apple Silicon doesn’t benefit as much as Intel)
- HDR video capture workflows
10GbE Option
The M4 Pro can be configured with 10 Gigabit Ethernet (instead of standard Gigabit). Essential for video professionals on shared media servers or large file transfers across LAN. Adds ~£150–200 to the price.
Can You Upgrade the M4 Pro?
No internal upgrades. The M4 Pro Mac Mini, like base M4, is completely sealed. RAM and storage are soldered and non-user-replaceable.
The strategy remains the same: choose your full configuration at purchase. M4 Pro buyers typically need either 24GB or 48GB RAM and 1TB–4TB storage. Decide this before ordering.
RAM Compatibility on M4 Pro
Why 48GB? For Whom?
The M4 Pro maxes out at 48GB unified RAM—suitable for:
- Professional video editors working with 6K+ timelines
- 3D artists (Cinema 4D, Blender heavy scenes)
- Development with large Docker container fleets
- Virtualisation labs (multiple VMs running)
Most developers and designers thrive on 24GB. Only upgrade to 48GB if you’re running resource-intensive professional software full-time.
Configuration Strategy
- 24GB M4 Pro — start here for developers, designers, standard creative work (£1099)
- 48GB M4 Pro — professional video, VFX, complex 3D, heavy virtualisation (£1299)
SSD Compatibility on M4 Pro
Storage Options & Sizing
M4 Pro supports 512GB, 1TB, 2TB, and 4TB internal storage—all soldered.
| Storage | Best For | Price (approx) |
|---|---|---|
| 512GB | System + apps only (external SSD required for project files) | +£0 |
| 1TB | Development, light creative work, reasonable project cache | +£200 |
| 2TB | Professional video editor, designer with large local libraries | +£400 |
| 4TB | Motion graphics, VFX house backup, high-capacity archive | +£800 |
External SSD Strategy via TB5
Thunderbolt 5 docks and external SSD enclosures are emerging. If you need >4TB total, a fast external RAID array connected via TB5 becomes practical. Current expansion options:
- Sonnet Echo Express — professional TB5/TB4 RAID enclosure
- OWC Mercury Pro RAID — Mac-optimized RAID storage
- Samsung T9 SSD — high-speed portable expansion
Prices for TB5 external storage remain premium (£400–800 for 4TB).
Power Supply & Thermal Design
190W USB-C Power Delivery
The M4 Pro draws more power (190W) than base M4 (140W). You’ll need a high-capacity USB-C charger or Thunderbolt dock supporting 190W+ PD. Check your dock specs before purchasing.
Passive Cooling, Sustained Loads
M4 Pro also uses passive cooling but runs slightly warmer than base M4 due to higher CPU/GPU clock speeds. In sustained workloads (video export, rendering), ensure adequate airflow. Ideal ambient temp: <20°C for comfort; acceptable up to 25°C.
Display & Docking for M4 Pro
Multi-Display Setup
M4 Pro supports:
- Up to 2× external 6K displays via TB5 (60Hz)
- Plus 1× display via HDMI 2.1 (4K 60Hz)
- Total: 3 external displays
This is ideal for video professionals who need timeline + reference monitor + colour grading display.
Thunderbolt 5 Dock Recommendations
TB5 docks are still emerging (early 2024). Current/upcoming options:
- Caldigit TS5 — 6 TB5 ports, 190W PD, Gigabit Ethernet
- OWC Thunderbolt 5 Hub — third-party TB5 option
- CalDigit TS4 — Fallback TB4 dock (TB5 backward-compatible at 40 Gbps)
WiFi 6E & 10GbE Comparison
Default: Gigabit Ethernet
M4 Pro comes with standard Gigabit Ethernet (1 Gbps). Adequate for most office work and cloud syncing.
10GbE Option: When to Buy
10 Gigabit Ethernet is recommended if:
- Your office/studio has 10GbE infrastructure
- You’re regularly transferring 50GB+ files across your LAN
- You’re connected to shared media servers (video facilities)
- You’re building a professional editing suite
If you’re on a residential ISP or typical office network, 10GbE offers minimal benefit. Stick with standard Gigabit Ethernet and save £150–200.
Upgradeability Score
| Category | Score | Notes |
|---|---|---|
| RAM Upgrade | 0/10 | Soldered; impossible |
| SSD Upgrade | 1/10 | Soldered; TB5 external expansion emerging |
| Ports & Connectivity | 9/10 | 3× TB5 + optional 10GbE = professional-grade expansion |
| Display Support | 9/10 | 3 external displays via TB5 + HDMI |
| Overall Upgradeability | 3/10 | Configuration at purchase essential for professionals |
Frequently Asked Questions
Should I buy M4 Pro or stick with base M4?
M4 Pro is worth it if you’re professional video editing, 3D work, or large-scale development. For general use, M4 is sufficient and £400–500 cheaper.
Is 24GB or 48GB RAM better value on M4 Pro?
24GB is excellent for most professionals and saves £200. Upgrade to 48GB only if you’re running simultaneous heavy workloads (large Blender scenes + video export + IDE).
Do I really need 10GbE?
Probably not unless you’re on a 10GbE-equipped LAN. Most home offices and SME studios don’t have 10GbE infrastructure. Standard Gigabit Ethernet is practical for 90% of workflows.
Can I add external GPU to M4 Pro?
No. Apple Silicon doesn’t support external GPUs (eGPU). GPU performance is baked into the M4 Pro chip. You cannot expand GPU capabilities post-purchase.
What’s the best SSD size for video editing on M4 Pro?
Minimum 2TB (system + scratch disk + media cache). Ideally 4TB if your projects exceed 100GB raw footage. Pair with fast external TB5 SSD for archive/LTO backup.
