Intel Core i5 8250U Avis | 78 Données comparées

The Intel Core i5-8250U introduces a significant, power-efficient quad-core, eight-thread design to thin-and-light laptops, offering up to 40% higher performance in multi-threaded tasks compared to previous dual-core generations. While excelling in multitasking and providing high single-core speed, a key drawback is its inability to maintain maximum Turbo speeds under prolonged, intensive loads due to power and thermal restrictions. The processor excels in efficiency, providing substantial power in a 15W package, though the integrated Intel UHD Graphics 620 remains unchanged and unsuitable for gaming. Performance heavily depends on the laptop's specific cooling solution, with the CPU often pairing best with dedicated GPUs to avoid shared power limitations.

The 2018 LG Gram 13 sets a high bar for portability, weighing only 965 grams while featuring an impressive 72 Wh battery that delivers exceptional, class-leading runtimes. Performance is driven by a quad-core Intel Core i5-8250U, providing a substantial 22% boost over previous dual-core models, supported by an exceptionally quiet cooling system that keeps surface temperatures comfortable. However, the laptop is limited by a slow SATA-based SSD, restricted 8GB/256GB configurations, a slightly flexible chassis, and the omission of Thunderbolt 3, with TechSpot highlighting it primarily for users prioritizing extreme mobility over premium features.

The NotebookCheck review of the HP 14-ma0312ng (i5-8250U, Optane Memory) highlights a capable 14-inch notebook hampered by display quality and initial thermal throttling, which was resolved by reverting to BIOS revision F.05. Pros include the performance of the Core i5-8250U with 8 GB of dual-channel RAM, alongside decent internal connectivity. However, the 14-inch TN panel is described as a major drawback, featuring a low 1,366 x 768 resolution, poor contrast (429:1), low brightness, and limited viewing angles. NotebookcheckThe device utilizes Intel Optane memory for improved responsiveness and features a two-tone anthracite and silver-gray design. The review notes that the case, inputs, and overall design are identical to the previously tested HP 14-bp001ng. NotebookcheckUltimately, the laptop's "bitterly disappointing" TN screen is highlighted as the primary con, making it hard to recommend for users needing high-quality visuals or outdoor usability. The review suggests the performance potential is significantly limited by this panel choice. Notebookcheck

The 8th Generation Intel "Kaby Lake Refresh" CPUs deliver a substantial performance leap for ultrabooks, with the Core i5-8250U demonstrating a 76% increase in Geekbench 4 scores over its predecessor. By doubling the core count to four in U-series processors, the chips provide vastly improved multitasking and heavy-load performance for tasks like 4K video transcoding. While offering superior power for short-term tasks, the 15-watt processors can struggle to maintain maximum turbo speeds under sustained loads due to thermal constraints. Overall, the 8th Gen chips offer significant improvements over 7th Gen models with minimal changes to integrated graphics performance. For more details, visit Laptop Mag.

The LaptopMedia comparison highlights a significant generational leap from the dual-core Core i5-7200U to the quad-core Core i5-8250U, which doubles the core count and cache while maintaining a 15W TDP. While the i5-8250U operates with a lower base clock (1.60GHz) to manage thermal limits, it delivers superior performance with higher boost clocks (3.40GHz) compared to the i5-7200U’s 2.50GHz base. Performance benchmarks indicate the i5-8250U is roughly 50-60% faster in multi-threaded scenarios, such as Cinebench and Adobe Photoshop, while graphics improvements are minimal due to the rebranded UHD Graphics 620. The primary advantage of the i5-8250U is its exceptional multi-tasking capability, providing near "HQ" performance in a portable package. Conversely, the lower base clock speed serves as a limitation, making the i5-7200U potentially more consistent for sustained, ultra-light tasks. The analysis concludes the i5-8250U offers a massive performance-per-watt advantage, making it the clear winner for modern computing needs. LaptopMedia

The Intel Core i5-8250U, an 8th-generation ultra-low voltage (ULV) processor, represents a significant jump from dual-core to a quad-core architecture with 8 threads. It delivers up to 40% higher multi-threaded performance than its predecessor, the i5-7200U, by operating between 1.6 GHz and 3.4 GHz while maintaining a 15W TDP. The CPU excels inburst performance, enabling faster handling of tasks like photo exports and light video editing, and is suitable for general productivity and casual gaming with its integrated UHD Graphics 620. Key drawbacks involve sustained performance, as the 15W TDP limit leads to thermal throttling, causing the CPU to drop from 3.4 GHz to roughly 2.2 GHz under continuous heavy loads. It is not designed for modern, demanding gaming or heavy workstation tasks without a dedicated GPU. Furthermore, as an older component, it is increasingly outpaced in instructions per clock (IPC) by newer generations. For more details, visit Notebookcheck.

The Intel Core i5-8250U, an 8th-generation Kaby Lake Refresh mobile processor, features 4 physical cores and 8 threads, providing up to a 40% performance increase in multi-threaded tasks compared to the previous i5-7200U. While the base clock is 1.60 GHz, it boosts up to 3.40 GHz, delivering strong performance for office work, web browsing, and mid-level multitasking. Key advantages include high efficiency with a 15W TDP for longer battery life and integrated H.265/HEVC 10-bit hardware acceleration. However, the CPU suffers from significant thermal throttling under sustained high loads. Additionally, the integrated Intel UHD Graphics 620 is insufficient for modern gaming, struggling with performance beyond 720p on low settings. Currently regarded as an entry-level to mid-range option, it fully supports Windows 11 and remains viable for general use, though it may struggle with heavy 3D modeling or intensive video rendering.

The 8th Gen Kaby Lake Refresh architecture brought a significant upgrade to 15W ULV chips by introducing quad-core, eight-thread configurations for both the Intel Core i5-8250U and i7-8550U. While the i7-8550U offers higher base/turbo clocks and a larger 8MB cache, both processors share identical integrated UHD Graphics 620, with the i7 providing a 20-30% performance lead in synthetic benchmarks. However, in real-world scenarios, the i7 only provides a marginal ~9% advantage, and both chips can suffer from performance throttling under sustained heavy workloads due to their low 15W TDP constraints. The review concludes that the Core i5-8250U offers better value for everyday multitasking, as the i7’s higher cost does not justify its minor performance boost for most users.
