Intel Core i7 11800H Avis | 78 Données comparées

The LaptopMedia review highlights a significant performance gap between the Intel Core i7-11800H and the i7-11390H, with the 45W H45-series chip (i7-11800H) vastly outpacing the 35W H35-series chip (i7-11390H) despite a minor TDP difference. The i7-11800H offers a major advantage with double the cores (8 vs 4), threads, and L3 cache, leading to over 100% higher 3D rendering performance, making it the clear choice for demanding workloads. While the i7-11390H provides higher peak clock speeds (up to 5.00 GHz) suitable for light tasks, its, primary, disadvantage lies in being confined to thinner laptops with inferior cooling that prevents it from sustaining that performance, resulting in significantly lower multi-core capability.

The Intel Core i7-11800H outperforms the i7-11600H, delivering 33% higher Cinebench R20 scores and faster photo editing due to its 8-core/16-thread architecture and 24MB L3 cache. While the 11800H offers superior, high-end performance, a con is its high reliance on robust cooling, despite a lower base clock (2.30GHz) compared to the 11600H. The i7-11600H functions as a high-value, 6-core alternative for mid-range gaming, offering a higher base clock (2.90GHz) and better price-to-performance, but it suffers from a significant multi-threaded deficit in professional workloads. Ultimately, the 11800H is superior for heavy productivity, while the 11600H excels in gaming, with both scaling performance to their specifications.

The LaptopMedia review highlights a massive performance leap from the 10th Gen Core i7-10750H to the 11th Gen Core i7-11800H, driven by a 10nm process, 8 cores/16 threads, and 24MB L3 cache. Key pros for the i7-11800H include a 66% higher Cinebench 20 score, support for faster 3200MHz RAM, Thunderbolt 4, and PCIe 4.0. Conversely, cons include higher costs and a necessity for robust cooling to manage increased heat output.

The PCWorld review of the 11th Gen "Tiger Lake-H" processors (specifically the Core i7-11800H) highlights Intel's return to competitive standing in the high-performance laptop market against AMD’s Ryzen 9 5000 series. The review notes that the chip is a "real contender" that trades near-even blows with rivals, particularly in gaming and lightly-threaded tasks, unlike previous 10th-gen parts. Key pros center on superior platform features, including a massive PCIe Gen 4 bandwidth advantage over Ryzen and strong performance in AI-based tasks using AVX-512 and DL Boost. In gaming-specific tests like Counter-Strike: Global Offensive, the chip maintained a 23% advantage over the competition. The cons indicate that while the platform is strong, Ryzen 9 5900HX maintains a small 7% lead in raw multi-core benchmarks like Cinebench R20. Furthermore, despite the PCIe win, the practical advantage is limited for current games, and thermal management remains a concern for these high-performance, 10nm chips.

The Intel Core i7-11800H (Tiger Lake H45) provides a significant 10nm performance leap, offering up to 50% higher multi-threaded performance than its predecessor and strong competition for AMD's Ryzen 7 5800H. Key pros include high IPC, 20 lanes of PCIe Gen 4 support, and leading performance in gaming, particularly in CPU-bound scenarios. A noted con is its high power consumption, as the processor is less efficient than AMD alternatives at lower power limits (35-60W), requiring high power usage (80W+) to reach maximum performance. Overall, the i7-11800H is an excellent, though power-hungry, choice for high-performance laptops needing robust cooling.

The XPG Xenia 15 KC, co-designed with Intel, is a thin-and-light gaming laptop featuring an Intel Core i7-11800H and NVIDIA RTX 3070, optimized for high performance and notably quiet operation, even under load. Key strengths include a lightweight 4.2-pound magnesium alloy chassis, a high-quality QHD 165Hz display, and a comfortable optical-mechanical keyboard. However, the laptop runs quite hot, has subpar speaker quality, and is considered less visually premium than some competitors.

The PCWorld review highlights the Dell XPS 17 9710 as a top-tier content creation laptop, featuring a brilliant 17-inch, 16:10 "InfinityEdge" display in a relatively compact chassis. Performance is a major pro, with 11th Gen Intel Core processors and RTX 3060 graphics delivering excellent results in creative apps, supported by robust vapor chamber cooling. Key strengths also include nearly 10-hour battery life during video playback and high-quality audio. However, the 720p webcam is noted as a disappointment for a premium device, and the lack of native USB-A or HDMI ports requires dongle usage. The keyboard, described as somewhat "bouncy" without a dedicated number pad, is another potential downside.

This LaptopMedia comparison analyzes the architectural differences between the 15W Intel Core i7-1255U and the 45W Core i7-11800H, highlighting a shift toward efficiency in modern, thin-and-light devices. While the i7-1255U leverages its hybrid architecture to compete in single-threaded tasks—even edging out the 11800H in Photoshop by 0.1 seconds—the older, high-power 11800H delivers superior sustained performance. The review concludes that while the i7-1255U excels in battery efficiency and burst responsiveness, the i7-11800H remains necessary for heavy-duty, multi-threaded workloads.

LaptopMedia compares the Intel Core i7-11390H (H35) and i7-11800H (H45), finding that despite similar branding, they differ significantly in architecture and performance. The i7-11390H offers high clock speeds (up to 5.0GHz) and strong integrated graphics (96 EUs) but is constrained by only 4 cores/8 threads and potential thermal throttling in thin chassis. Conversely, the i7-11800H acts as a "sleeper" CPU, providing double the cores, threads, and cache, which translates to a 113% performance advantage in 3D rendering. While the 11800H requires more robust cooling due to its 45W TDP, it is identified as the superior choice for performance, leaving the H35-based chip in an awkward, inefficient market position.

Intel’s 11th-gen "Tiger Lake H" processors mark a strong comeback, outperforming 10th-gen chips and challenging AMD's Ryzen 5000 in single-core performance and gaming, notably with a 9% lead over the Ryzen 9 5900HX in certain benchmarks. While Intel takes the lead in content creation (Adobe suite) and CPU-bound gaming like Rainbow Six Siege, a major drawback for these high-performance laptops is their higher power consumption and reliance on robust cooling, which can cause thermal issues. Conversely, AMD's Ryzen 5000 remains superior in multi-threaded productivity tasks and efficiency, offering better battery life, though it now faces stiff competition in pure, high-refresh-rate gaming.
