CPU Comparison
Intel Core i7-3537U vs Intel Core i3-1215U
A side-by-side comparison of specs, performance and value. The Intel Core i7-3537U is an ultra-low voltage mobile processor launched in January 2013 as a minor refresh within the Ivy Bridge family. Designed for thin-and-light laptops and ultrabooks, it operates at a 17-watt TDP. Built on Intel's 22nm process, it features 2 cores and 4 threads. The processor runs at a base clock of 2.0 GHz and can boost up to 3.2 GHz, offering a slight frequency bump over the older i7-3517U. It includes 4MB of L3 cache and supports dual-channel DDR3 memory. The integration of Intel HD Graphics 4000 provides capable multimedia performance for a chip of its era. While its dual-core architecture is a major bottleneck by modern standards, the 3537U was a reliable performer in 2013, bringing snappy single-core responsiveness to premium portable systems.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Slow for modern office tasks and multitasking.
Handles standard office applications and web browsing smoothly. Heavier multitasking with many browser tabs and applications can show some slowdown.
Gaming
Cannot run modern games; struggles with basic 3D.
Not designed for gaming. The UHD 64EU can handle very light casual titles but modern AAA games are unplayable.
Virtualization
Not recommended due to 2 cores.
8 threads allow for a lightweight VM alongside host tasks, but this is not a virtualization-focused part.
Efficiency
17W TDP was efficient in 2013, but outdated now.
The 15W base TDP with Intel's Thread Director scheduler enables efficient power distribution between P and E cores.
Specialized Performance
AI / ML
- No AI hardware
- No dedicated AI acceleration hardware
- 2 P-cores provide limited CPU inference capability
- Not suitable for AI or ML development workloads
Content Creation
Gaming
- HD 4000 is too weak
- Only suitable for older 2D games
- Not designed for gaming workloads
- UHD 64EU can manage 2D games and very basic 3D
- Modern AAA titles will not run at playable frame rates
- Older eSports titles at lowest settings may be marginally playable

Our Verdict on Each
A capable 2013 ultrabook chip, but its dual-core design is too slow for modern multitasking.
Best for: When considering the Intel Core i7-3537U today, it is crucial to recognize its age and severe limitations. It should only be purchased in the used market at a significant discount. It remains capable of basic web browsing, document editing, and media consumption, but its 2-core, 4-thread design is a major bottleneck for modern multitasking and web applications. Avoid purchasing a laptop with this CPU if you need to do any modern productivity work, video editing, or gaming. It is best suited for budget-conscious buyers who need a cheap, secondary machine for light web browsing or for students on a very tight budget who only need to write papers. For any primary computing needs, investing in a newer platform is strongly recommended.
Read the full reviewA competent entry-level hybrid mobile chip that introduced the P+E architecture to the i3 laptop segment. Adequate for everyday tasks, though the 8-thread ceiling and 15W power limit constrain heavier workloads.
Best for: Purchasing a budget to mid-range laptop in 2022-2023 for everyday tasks, schoolwork, and office use where battery life matters more than raw performance.
