Quick Answer
The Intel Core Ultra 5 238V and 236V are closely related mobile processors from the Lunar Lake generation, designed for thin-and-light laptops. The primary differences lie in their CPU and GPU clock speeds, with the 238V offering slightly higher performance across both components, while core counts, architecture, and key platform features remain identical.
Intel Core Ultra 5 238V vs Intel Core Ultra 5 236V: Full Comparison
Choosing the right processor is a key decision when selecting a new laptop. Within Intel’s Lunar Lake lineup, the Core Ultra 5 series offers a balance of efficiency and performance for modern productivity and content consumption. This comparison breaks down the specifications and expected performance differences between the Core Ultra 5 238V and the Core Ultra 5 236V, helping you understand which chip might be better suited to your needs.
CPU Architecture and Core Configuration
Both processors are built on the same Lunar Lake microarchitecture and share an identical core configuration. This means the fundamental design and capabilities are very similar.
- Shared Configuration: Both chips feature a hybrid design with 4 Performance-cores (P-cores) and 4 Efficient-cores (E-cores), for a total of 8 cores and 8 threads. They also include 2 Low Power Island E-cores for background tasks.
- Clock Speed Difference: The main point of differentiation is clock speed. The Core Ultra 5 238V has a slightly higher maximum turbo frequency. Its P-cores can boost up to 4.7 GHz, compared to 4.6 GHz on the 236V. The base clock speeds for the performance cluster also differ, with the 238V starting at 2.5 GHz versus 2.3 GHz for the 236V.
- Implication: The 238V is positioned to deliver marginally higher peak CPU performance in short, bursty workloads and sustained tasks when thermal conditions allow.
Integrated Graphics (GPU) Performance
The integrated GPU is a significant component of these processors, handling display output, video playback, and light gaming.
- Shared GPU: Both models integrate the same Intel Arc graphics based on the Xe2 architecture, with 7 Xe-cores.
- Clock Speed Difference: Similar to the CPU, the GPU clock speed is where they diverge. The Core Ultra 5 238V’s GPU has a maximum graphics frequency of 2.15 GHz, while the 236V’s GPU operates at up to 2.05 GHz.
- Implication: The 238V will generally offer slightly better graphics performance. This could translate to a few extra frames per second in games or slightly smoother performance in creative applications that leverage GPU acceleration.
Platform Features and Efficiency
As part of the same generation and series, the two chips share an extensive set of platform technologies.
- AI Acceleration: Both include a dedicated Neural Processing Unit (NPU) for accelerating AI workloads, with the same performance tier (approximately 40 TOPS combined with CPU and GPU).
- Memory and I/O: They support the same LPDDR5X memory technology and offer identical PCIe lane configurations and modern I/O support like USB4 with Thunderbolt 4.
- Power and Thermal Design: Both processors share the same base power (TDP) and similar configurable power ranges. Real-world battery life in a given laptop model will depend more on the device’s overall design (battery capacity, display, etc.) than on the small clock speed difference between these two CPUs.

Frequently Asked Questions
What is the main difference between the Core Ultra 5 238V and 236V?
The primary difference is clock speed. The Core Ultra 5 238V has slightly higher maximum turbo frequencies for both its CPU performance cores (4.7 GHz vs. 4.6 GHz) and its integrated GPU (2.15 GHz vs. 2.05 GHz) compared to the 236V.
Will the Core Ultra 5 238V provide noticeably better battery life?
Typically not. Both chips share the same architecture, core configuration, and base power rating. The small clock speed difference is unlikely to create a significant variance in battery life, which is generally more influenced by the laptop’s display, battery capacity, and user activity.
Is the AI performance different between these two processors?
No, the AI performance is essentially identical. Both feature an NPU with the same performance tier, and the total platform AI compute (NPU + CPU + GPU) is rated for approximately 40 TOPS for each model.
Which processor is better for light gaming?
The Core Ultra 5 238V, with its marginally higher GPU clock speed, may offer slightly better performance in light gaming scenarios. However, the difference is expected to be small, as they use the same GPU architecture with the same number of execution units.
Final Thoughts
The Intel Core Ultra 5 238V and 236V are remarkably similar, sharing the same core architecture, core count, AI capabilities, and platform features. The 238V holds a slight performance advantage due to its higher CPU and GPU clock speeds, which may be a factor in performance-sensitive applications. In practice, for most general computing tasks, the difference may be minimal. The choice between them in a laptop will often come down to specific device availability, configuration, and pricing, as the overall user experience provided by either chip is expected to be very comparable.
