CPU Comparison
Intel Core i3-1000NG4 vs Intel Core i3-1005G1
A side-by-side comparison of specs, performance and value. The Intel Core i3-1000NG4 is a custom-engineered, Apple-exclusive Ice Lake-Y processor featuring two Sunny Cove cores and a 48EU Iris Plus GPU, designed specifically for the early 2020 MacBook Air.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Adequate for lightweight office work on older macOS versions, but modern updates have made it feel sluggish.
Single-app use is fine, but opening multiple browser tabs alongside Office apps will cause noticeable slowdowns.
Gaming
The 48EU Iris Plus can handle very light casual games, but Macs are not gaming devices and this CPU limits even Mac-specific titles.
The basic UHD graphics are too weak for any meaningful gaming experience.
Virtualization
Running Windows via Boot Camp or virtualization is possible but painfully slow with only 4 threads.
2 cores and 4 threads are barely enough for the host OS, let alone a virtual machine.
Efficiency
Excellent efficiency for an x86 chip, though it was immediately overshadowed by the ARM-based M1's efficiency.
Good efficiency for a 15W chip, allowing for 6-8 hours of real-world battery life in basic ultrabooks.
Specialized Performance
AI / ML
- DLBoost is present but largely unused in the macOS ecosystem of that era
- DLBoost is supported but the 2-core CPU heavily limits AI workload processing
Content Creation
Gaming
- MacBook Airs are not gaming devices
- The CPU will bottleneck even lightweight games running via Rosetta or ports
- The basic UHD graphics lack the power for even casual gaming
- CPU will bottleneck any game that relies on more than two threads

Target Audience
Strengths & Weaknesses
Pros
- Historically significant as one of Apple's final custom Intel chips
- 48EU Iris Plus offers decent legacy graphics performance for macOS
- Very low power draw results in a quiet, cool MacBook Air
- Capable of running Intel-only legacy software
Cons
- Only 2 CPU cores make modern macOS feel incredibly slow
- Instantly obsolete upon the announcement of the Apple M1
- Cannot be upgraded to future macOS versions that drop Intel support
- Limited to PCIe 3.0 speeds
- Poor value on the used market compared to M1 Macs
Pros
- Native Thunderbolt 3 support is excellent for docking stations
- Sunny Cove architecture provides strong single-thread performance for basic tasks
- 15W TDP allows for slim, portable laptop designs
- DDR4 and LPDDR4X memory flexibility
- 10nm process was very efficient for its time
Cons
- Only 2 cores and 4 threads, which is inexcusable at its $281 MSRP
- Basic UHD graphics lack the power of the Iris Plus found on other Ice Lake chips
- No PCIe 4.0 support
- Cannot handle modern multi-tab browsing without stuttering
- L3 cache is limited to 4 MB

Our Verdict on Each
A fascinating piece of silicon history due to its Apple exclusivity and 48EU GPU, but entirely outclassed by the Apple M1 that replaced it just months after its release.
Best for: The only reason to acquire an i3-1000NG4 MacBook Air today is for vintage Apple hardware collection, or if you require an Intel-based Mac specifically to run legacy 32-bit macOS software or older audio production plugins that are not compatible with Apple Silicon. If you find one for under $150, it can serve as a dedicated typing machine or basic web browser for a child.
Read the full reviewThe i3-1005G1 successfully brought 10nm and Thunderbolt 3 to cheap laptops, but its 2-core CPU and stripped-back graphics make it a poor choice for anything beyond light tasks.
Best for: The only scenario where an i3-1005G1 laptop makes sense is if it is being sold at an extreme clearance price (under $100) and you need a disposable machine for a child's schoolwork or a dedicated document viewer. The inclusion of Thunderbolt 3 means it can connect to high-speed docks, which might be useful for legacy office setups.
