Intel Core Ultra X7 358H and Ultra 5 338H Leak Reveals Performance
As the technology landscape evolves at a breakneck pace, Intel's upcoming CPU lineup has garnered significant attention, particularly the Panther Lake series. With promising specifications and performance leaks emerging, enthusiasts and professionals alike are eager to understand what these new processors bring to the table. This article delves into the anticipated performance metrics, comparisons with current models, and what users can expect from Intel's Panther Lake CPUs.
Performance Expectations for Intel Panther Lake CPUs
Recent leaks suggest that Intel's Panther Lake processors, specifically the Core Ultra X7 358H and Core Ultra 5 338H, may deliver performance similar to that of the Arrow Lake series in multi-threaded tasks. This revelation comes after initial benchmarking data was released, showing the potential capabilities of these new chips.
According to reports from LaptopReview, the Core Ultra X7 358H is set to feature a configuration of 4 Performance Cores (P-Cores) and 12 Efficiency Cores (E-Cores) with a boost clock reaching up to 4.8 GHz. In contrast, the Core Ultra 5 338H will showcase 4 P-Cores and 8 E-Cores, with a maximum clock speed of 4.7 GHz. These specifications are indicative of a robust architecture aimed at enhancing multitasking and overall performance.
When pitted against existing Arrow Lake CPUs, the Panther Lake models demonstrate competitive performance metrics. For instance, the X7 358H was benchmarked against the Arrow Lake's Core Ultra 7 255H, which features a higher core count and clock speed. Despite these differences, early results indicate that Panther Lake could hold its ground.
- Core Ultra X7 358H: 4 P-Cores + 12 E-Cores @ 4.8 GHz
- Core Ultra 7 255H: 6 P-Cores + 10 E-Cores @ 5.1 GHz
- Core Ultra 5 338H: 4 P-Cores + 8 E-Cores @ 4.7 GHz
- Core Ultra 5 225H: 4 P-Cores + 10 E-Cores @ 4.9 GHz
Benchmark Comparisons: Panther Lake vs. Arrow Lake
Benchmark scores provide a clearer picture of the performance landscape. The Intel Core Ultra X7 358H reportedly scored around 20,000 points in the Cinebench R23 Multi-Thread test, while the Core Ultra 7 255H achieved approximately 21,826 points under the same conditions. Similarly, the Core Ultra 5 338H scored around 16,000 points, whereas its predecessor, the Core Ultra 5 225H, managed 17,988 points.
This data suggests that Panther Lake CPUs are not only competitive but may also exhibit performance enhancements in final silicon versions. Historically, Intel has seen improvements from initial samples to retail products, so expectations are high for the Panther Lake series.
Architectural Advantages of Panther Lake
Intel has emphasized that Panther Lake CPUs could offer significant enhancements in power efficiency, claiming up to a 30% reduction in power consumption while maintaining comparable performance to Arrow Lake in multi-threading tasks. This efficiency could translate to better battery life and lower heat generation, making these processors particularly attractive for mobile platforms.
The architecture of Panther Lake introduces several key features:
- Hybrid Core Design: Combines P-Cores and E-Cores to optimize performance across different workloads.
- Higher Clock Speeds: Boost clocks nearing 5 GHz can significantly enhance single-threaded performance.
- Improved iGPU Performance: Initial benchmarks show a notable increase in graphics capabilities with the integrated 12 Xe3 iGPU.
Intel’s Panther Lake Release Timeline
Intel has indicated that the first Panther Lake SKU is expected to launch in the current quarter, with further SKUs anticipated for a more comprehensive rollout. An official launch event is slated for CES 2026, where additional details regarding pricing and availability will likely be unveiled.
Intel Panther Lake-H and U Lineup Overview
Below is a preliminary overview of the Intel Panther Lake-H and U CPU lineup, laying out the specifications for these upcoming processors:
| CPU Model | P-Cores (Cougar Cove) | E-Cores (Darkmont) | LP-E Cores (Skymont) | CPU Clocks (Max) | Xe3 iGPU Cores | iGPU Clock | TDP |
|---|---|---|---|---|---|---|---|
| Core Ultra X9 388H | 4 | 8 | 4 | 5.1 GHz | 12 | TBD | 25W (65-80W Turbo) |
