Intel Core i5-1035G1: Analysis of the Processor for Ultrabooks in 2025
Updated: April 2025
Introduction
The Intel Core i5-1035G1 processor, released in 2019, remains a popular choice for budget ultrabooks. Despite the emergence of newer generations (such as Meteor Lake and Lunar Lake), its balance of price and performance keeps it relevant for users who do not require maximum power. In this article, we'll explore who this CPU will suit in 2025, how it handles tasks, and which laptops to consider.
Architecture and Process Technology
Ice Lake: Transition to 10nm
The Core i5-1035G1 belongs to the Ice Lake generation—the first mass-market 10-nanometer process from Intel. This transition helped reduce power consumption and increase transistor density.
- Cores and Threads: 4 cores, 8 threads (Hyper-Threading).
- Frequencies: Base frequency of 1.0 GHz, maximum turbo frequency of 3.6 GHz. The low base frequency is due to optimization for a TDP of 15 Watts.
- Cache: 6 MB L3.
- Integrated Graphics: Intel UHD Graphics G1 (32 EUs). It supports 4K@60 Hz but is not intended for gaming.
Key Improvements of Ice Lake:
- Support for PCIe 4.0 (though many laptops from 2019–2021 used PCIe 3.0).
- Built-in support for Thunderbolt 3 and Wi-Fi 6.
- Enhanced AI accelerator (Intel DL Boost) for machine learning tasks.
Power Consumption and TDP
Thermal Design Power of 15 Watts: Balance Between Power and Battery Life
The 15W TDP is standard for ultrabooks. This means the processor:
- Operates quietly: Cooling systems do not require powerful fans.
- Consumes little power: Ideal for slim laptops.
- May limit performance under sustained workloads (e.g., video rendering).
Example: In passively cooled laptops (like the Microsoft Surface Laptop Go), the i5-1035G1 uses turbo mode less frequently to avoid overheating.
Real-World Performance
Office and Multimedia
- Office Applications: Microsoft Office, Google Workspace—no delays even with a dozen browser tabs open.
- Photo Editors: Adobe Photoshop runs smoothly, but filters on 4K photos may process slower than on a CPU with a TDP of 28 W.
- Video: Streaming 4K (Netflix, YouTube)—no issues. Rendering 1080p in DaVinci Resolve takes 2–3 times longer compared to the Ryzen 5 5500U.
Gaming
The integrated UHD G1 graphics can only handle light tasks:
- CS:GO: 720p, low settings—40–50 FPS.
- Minecraft: 1080p, medium settings—50–60 FPS.
- Indie games (Hollow Knight, Stardew Valley)—consistently 60 FPS.
Turbo Mode: Under peak loads (like launching a game), the frequency rises to 3.6 GHz but then drops to 2.5–2.8 GHz after 2–3 minutes due to heat.
Use Cases
Who is the i5-1035G1 For?
1. Students and Office Workers: Document work, Zoom calls, web browsing.
2. Travelers: Lightweight laptops (1–1.5 kg) with 8–10 hours of battery life.
3. Home Users: Watching movies, social media, simple photo editing.
Who It’s Not For:
- Gamers: A discrete graphics card is required.
- Designers/Video Editors: Insufficient power for 3D rendering or 4K video.
Battery Life
How Does 15W TDP Impact Runtime?
- Video Playback: Up to 10 hours (at 50% screen brightness, Wi-Fi on).
- Web Browsing: 7–8 hours.
- Idle: Up to 12 hours (power-saving mode).
Power Saving Technologies:
- Intel Speed Shift: Dynamic frequency adjustment to lower power consumption.
- Dynamic Tuning 2.0: Real-time load adaptation.
Tip: Choose laptops with batteries around 50 Wh (for example, the ASUS ZenBook 13 UX325EA—14 hours of operation).
Comparison with Competitors
AMD Ryzen 5 4500U (2020)
- Pros: 6 cores/6 threads, better performance in multi-threaded tasks.
- Cons: Integrated Vega 6 graphics are weaker in gaming compared to Iris Xe in newer Intel chips.
Apple M1 (2020)
- Pros: Better battery life (up to 18 hours), higher speed in “native” applications.
- Cons: Limited compatibility with Windows.
Intel Core i5-1135G7 (Tiger Lake, 2020)
- Pros: Iris Xe graphics (80 EUs), PCIe 4.0 support.
- Cons: Price is 20–30% higher.
Conclusion: In 2025, the i5-1035G1 falls short against newer models but excels in the budget segment (laptops under $700).
Pros and Cons
Strengths:
- Low price of laptops ($500–$800).
- Support for Thunderbolt 3 and Wi-Fi 6.
- Adequate performance for everyday tasks.
Weaknesses:
- Outdated architecture (by 2025, characterized by AI accelerators and 5nm technology).
- Limited headroom for multitasking.
- Lack of PCIe 4.0 support in most models.
Recommendations for Laptop Selection
Types of Devices:
- Ultrabooks: Dell XPS 13 (from $600), Lenovo IdeaPad 5.
- Convertible Laptops: HP Envy x360 (from $650).
What to Look For:
1. Display: Minimum Full HD, IPS panel.
2. RAM: 8 GB minimum, 16 GB for multitasking.
3. Storage: SSD 512 GB.
4. Ports: USB-C with Thunderbolt 3 for connecting monitors and docks.
Example: Acer Swift 3 (2024) with i5-1035G1, 16 GB RAM, SSD 512 GB—$699.
Final Conclusion
The Intel Core i5-1035G1 in 2025 is a choice for those who:
- Are looking for an affordable laptop ($500–$800).
- Do not play AAA games or work with "heavy" applications.
- Value battery life and portability.
Key Benefits:
- Accessibility.
- Modern interfaces (Thunderbolt 3, Wi-Fi 6).
- Quiet operation and minimal heating.
If your budget allows, consider laptops with processors from the Intel Core 12th generation or AMD Ryzen 7000 series, as they offer better price-to-performance ratios. However, for basic tasks, the i5-1035G1 remains a reliable option.
