Intel Core i5 8400H Avis | 78 Données comparées

The Intel Core i5-8400H is a Coffee Lake-generation, 4-core/8-thread mobile processor designed for high-performance 45W laptops. Based on Geekbench 6 data, it delivers strong performance with a ~1,493 single-core and ~4,963 multi-core score, operating between 2.50 GHz and 4.20 GHz. Pros include high turbo speeds for responsiveness and capable legacy performance similar to older i7-7920HQ chips. Cons involve high thermal output requiring robust cooling and a locked multiplier for overclocking. Furthermore, as a 14nm 2018 chip, it is outpaced by newer, more efficient 6-core or 8-core mobile processors. View the full performance data on the Geekbench Browser.

The Intel Core i5-8400H is a 14nm Coffee Lake mobile processor featuring 4 cores, 8 threads, a 2.5 GHz base, and a 4.2 GHz turbo boost designed for 45W high-performance laptops. Key advantages include strong multi-threaded performance comparable to previous-generation high-end desktops and robust virtualization support. However, limitations include its age in the current market, a locked multiplier preventing overclocking, and lower core counts compared to modern competitors.

The Dell Latitude 5491 is a 14-inch business laptop designed as a "pinstriped overkill" machine, offering workstation-level performance in a corporate chassis. Featuring a powerful six-core Intel Core i7-8850H processor, it excels at heavy-duty tasks but is often excessive for standard office work. Pros include exceptional multithreaded performance, a comfortable keyboard, and extensive port selection, including Thunderbolt 3, VGA, and Ethernet. However, this high-performance, 45-watt processor makes the laptop costly—tested at $2,370—and results in noisy fan noise under load. Additionally, the 1080p touch screen is criticized for being dim and highly reflective, hindering usability in bright environments. While durable (MIL-STD tested), the unit is heavier and bulkier than competitors like the Lenovo ThinkPad X1 Carbon. Battery life is considered unexceptional compared to lower-powered alternatives, and the Nvidia GeForce MX130 graphics are only a minor upgrade over integrated solutions. The device ultimately targets a niche, performance-hungry audience rather than typical office users. PCMag UK

The Dell Latitude 5491 is a 14-inch business laptop designed as a "workstation in a corporate chassis," featuring a powerful six-core Intel Core i7-8850H processor that excels in CPU-intensive tasks. While it maintains a professional, understated design, the high-performance components lead to significant heat, resulting in a notably loud cooling fan under load. Furthermore, the laptop's battery life is subpar compared to lighter alternatives, and the 1080p touch screen is criticized for being dim and highly reflective. Despite these compromises, the machine offers exceptional connectivity—including VGA, Ethernet, and Thunderbolt 3—and a comfortable, tactile keyboard with a dual pointing system. It provides excellent performance for video editing or data-heavy applications, though it may be overkill for standard office work. The review suggests the high cost of this configuration makes it a niche, specialized tool rather than a general-purpose laptop. PCMag UK
