CPU Comparison
Intel Core i5-1030G7 vs Intel Core i3-1125G4
A side-by-side comparison of specs, performance and value. The Intel Core i5-1030G7 is a low-power mobile processor engineered for ultra-thin laptops and fanless designs, debuting as part of the 10th Generation Ice Lake-Y family. Built on Intel's 10nm process, it features four cores and eight threads, leveraging the Sunny Cove microarchitecture to deliver noticeable single-threaded performance improvements over previous generations. Operating at a low 9-watt TDP, with configurable options up to 12 watts, it balances battery life and responsive computing. The inclusion of Iris Plus graphics with 64 execution units marks a significant leap in integrated visual performance, capable of handling casual gaming and hardware-accelerated media workloads. With support for LPDDR4X memory at 3733 MT/s and PCIe Gen 3, the chip ensures fast data throughput. Designed for premium mobility, it targets professionals and students needing long-lasting battery endurance without sacrificing essential productivity capabilities in highly portable form factors.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Snappy for everyday office tasks and multitasking, though heavy rendering is slowed by the 9W TDP.
Four cores handle office suites, video conferencing, and moderate multitasking with ease.
Gaming
Capable of running older or well-optimized games at low settings, but struggles with modern AAA titles.
The Iris Xe GPU can handle e-sports titles like League of Legends and CS:GO at 1080p low, but it is not meant for modern AAA gaming.
Virtualization
Can handle light virtualization, but resource constraints limit complex setups.
Can run a single lightweight virtual machine or Docker containers, but 8 threads limit heavy virtualization.
Efficiency
Outstanding power efficiency tailored for all-day battery life in ultra-portables.
Excellent power efficiency when paired with LPDDR4X memory, allowing for long battery life in ultrabooks.

Our Verdict on Each
A highly efficient 10nm chip that brought modern Sunny Cove architecture and Gen 11 graphics to ultra-portable devices, though its low TDP limits sustained multi-core performance.
Best for: Purchasing a used or discounted fanless ultra-thin laptop for basic productivity.
Read the full reviewThe i3-1125G4 was an excellent mainstream mobile processor in 2021, bringing 4 cores and 8 threads to the i3 laptop tier alongside a significant iGPU upgrade, though it has since been surpassed by 12th-gen parts.
Best for: You should only consider buying a laptop with the i3-1125G4 today if it is being offered at a significant, heavily discounted clearance price. At launch, it was a fantastic chip for students and office workers, offering enough power for daily tasks and capable integrated graphics. However, as an end-of-life product, paying standard retail pricing for it is unwise. The newer 12th-generation i3-1215U offers hybrid P-cores and E-cores for similar money, providing much better performance and longevity. If you find a used 1125G4 laptop incredibly cheap, it remains a perfectly viable machine for web browsing and document editing.
