A side-by-side comparison of specs, performance and value. The Intel Core i5-1135G7 is a 4-core, 8-thread mobile processor launched in September 2020. Built on the 10nm SuperFIN process, it utilizes the Willow Cove microarchitecture. Designed for thin-and-light laptops, it operates at a 15W TDP with a base clock of 1.5 GHz and a turbo boost up to 4.2 GHz. It features the highly capable Iris Xe Graphics G7 with 80 Execution Units, bringing significant gaming and media improvements to the ultrabook segment.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Snappy performance for everyday office tasks and multitasking.
The 4 cores provide a solid foundation for office multitasking, easily handling dozens of browser tabs alongside office applications.
Gaming
Capable of playing e-sports titles and older games at 1080p thanks to Iris Xe graphics.
The Iris Xe G4 graphics are better suited for video output than gaming. Only the lightest e-sports titles are playable.
Virtualization
Can handle light virtualization but is limited by 4 cores.
8 threads allow for running a couple of standard VMs, but the 15W TDP limits heavy sustained virtualization workloads.
Efficiency
Excellent power efficiency due to the 10nm SuperFIN process.
The IPU 6.0 actually improves overall system efficiency by offloading video processing tasks from the CPU and GPU.
Specialized Performance
AI / ML
- DLBoost and GNA 2.0 provide solid AI acceleration for background blur and noise cancellation.
- The IPU 6.0 provides dedicated AI acceleration specifically for image and video processing
- Lacks a general-purpose NPU for broad AI workloads
- AVX-512 supports CPU-based AI inference
Content Creation
Gaming
- Iris Xe 80EU allows for smooth e-sports gaming.
- Performance scales heavily with dual-channel memory.
- Not suitable for modern AAA gaming at high settings.
- G4 tier Iris Xe graphics limit graphical fidelity
- CPU is adequate for low-end gaming if paired with an external GPU via PCIe
- Not designed or marketed for gaming workloads
