With Intel’s latest Intel Core Ultra processor series, mobile computer speed has improved due to cutting-edge designs, battery economy, and integrated graphics. The Intel Core Ultra 5 125H and Core Ultra 5 135H are new high-performance laptops for thin-and-light and creative users. To assist you choose, this article analyses various CPUs’ features, characteristics, and real-world performance.
Overview of the Intel Core Ultra 5 Series
With the latest generation of Ultra processors, Intel’s mid-tier offering is represented by the Core Ultra 5 series. Intel 4 process technology powers these 7nm CPUs. Multitasking, productivity, gaming, and creativity are prioritised with these CPUs while preserving battery life.
125H and 135H Intel “H” CPUs power portable workstations and gaming laptops. Although similar, the 125H vs. 135H CPU number promises higher performance and features.
Core Architecture and Performance
Based on Intel’s new hybrid architecture, which combines Performance (P) and Efficient (E) cores, the 125H and 135H are both processors. Using efficiency cores for light background work and high-performance cores for demanding applications allows the processor to optimise power consumption.
Intel Core Ultra 5 125H: Four E-cores and six P-cores make up the Intel Core Ultra 5 125H’s 10-core design. This lets it multitask and run smoothly in a single thread. The majority of productivity workloads are easily handled by its 16 threads.
Intel Core Ultra 5 135H: Provides a more robust 12-core configuration with four E-cores and eight P-cores for a total of 20 threads. The additional core count greatly improves multitasking and parallel workloads, which makes the 135H more appropriate for heavy multitasking, content production, and certain professional applications.
Because the 135H has a higher base and turbo frequency, it responds faster and performs better under burst loads. The clock speeds also differ somewhat.
Cache and Memory
The speed and efficiency of the CPU depend on the cache memory. Larger caches (both L2 and L3) on the 135H aid in lowering memory latency and accelerating data access. Video editing, graphics, and gaming benefit from additional cache because they retrieve data often.
Both CPUs are compatible with DDR5-5600 and LPDDR5-6400. This ensures fast memory bandwidth for the combined GPU and CPU cores.
Integrated Graphics
Included in both CPUs is Intel’s specialized mobile graphics solution, the ARC A370M GPU. This graphics card provides respectable performance for GPU-accelerated tasks, multimedia editing, and light gaming. For tiny and light laptops that require capable integrated graphics, the ARC A370M is a good option, even while neither is intended to take the place of a dedicated high-end gaming GPU.
Power Consumption and Thermal Design
The 125H and 135H processors from Intel are designed to have a customisable TDP of 28W base and up to 45W maximum. According to the design of the gadget, laptop makers can thus optimise cooling solutions. Because of their same power envelope, these chips can be used in more durable gaming machines or small, light laptops without significantly sacrificing thermals or battery life.
In practical applications, the 135H’s increased core count and speeds may cause it to consume a little more power during intensive multitasking or multithreaded tasks; however, Intel’s power management and an effective core design help maintain a decent battery life.

Performance in Real-World Usage
Productivity and Multitasking
Web browsing, office applications, and media consumption are all handled well by both CPUs for daily productivity, but the 135H offers a more responsive experience when running several demanding apps at once. Because of its additional performance cores and threads, the 135H will render video editing programs like Adobe Premiere or DaVinci Resolve more quickly.
Gaming
Even though they aren’t specifically designed for gaming, both CPUs can run a lot of games when partnered with the appropriate GPU. The higher clock rates and more cores of the 135H give it a modest advantage in games that are CPU-bound or multi-core optimised.
Content Creation
The 135H’s extra cores and threads will be especially useful for professionals and content creators that perform tasks like writing, compiling, generating 3D environments, or operating virtual machines. Performance is further enhanced for intricate operations by its larger cache.
Practical Use Cases
Intel Core Ultra 5 125H
- For daily tasks like office work, streaming, and browsing, you want a reliable performer.
- You don’t need a lot of multi-core processing power for your moderate gaming or creative activities.
- You desire reasonable performance but place a higher priority on battery life and cost reductions.
