Intel Core i7 8705G Avis | 78 Données comparées

The Intel Core i7-8705G (Kaby Lake G) is a specialized 2018 mobile processor integrating a 4-core CPU with custom Radeon RX Vega M GL graphics, achieving a CPU Mark score of approximately 9,877. A major pro is its powerful integrated GPU performance, which rivals dedicated NVIDIA GTX 1050 graphics within compact devices, though a significant con is its high 65W TDP that demands substantial cooling. While offering superior multi-threaded performance (approx. 32% faster) compared to standard U-series chips like the i7-8550U, it cannot match 6-core processors like the i7-8750H, making it an "all-in-one" solution for moderate gaming and creative tasks rather than raw computing.

The TechSpot review of the Intel Core i7-8705G (Kaby Lake-G) highlights a unique, compact collaboration combining a quad-core Intel CPU with a custom AMD Radeon RX Vega M GL GPU, utilizing Intel's EMIB technology to link graphics with 4GB of HBM2 memory. A key pro is the mid-range gaming performance that generally outpaces a GTX 1050, allowing for powerful yet thin, space-efficient, and efficient laptop designs. However, the chip is constrained by using a quad-core Kaby Lake architecture rather than newer 6-core options, resulting in inferior multi-threaded productivity performance and a high cost, often making it less appealing than traditional CPU and discrete GPU pairings.

The PCWorld review highlights the Intel Core i7-8705G as an innovative hybrid chip merging a quad-core Intel CPU with AMD Radeon RX Vega M GL graphics, offering discrete-class performance in a compact form factor. Key advantages include impressive thermal management under heavy, combined workloads and space-saving integration of HBM2 memory, which enables high-end performance in thin, 2-in-1 devices. However, the review notes the quad-core architecture faces competition from newer 6-core processors, with gaming performance proving inconsistent compared to a dedicated GeForce GTX 1050.

The Intel Core i7-8705G (Kaby Lake-G) is a unique 2018 quad-core processor featuring integrated Radeon RX Vega M GL graphics and 4GB of HBM2 memory, achieving Geekbench 6 scores of roughly 1,286 single-core and 4,003 multi-core. Its primary advantage is remarkable space efficiency, enabling entry-level gaming performance in thin, portable laptops like the Dell XPS 15 2-in-1, with graphics performance roughly equivalent to a GTX 1050. However, the chip faces significant limitations in multi-threaded tasks compared to later 6-core 8th-gen processors, alongside potential driver compatibility issues and higher costs.

LaptopMedia compares the 8th Gen Intel Core i7-8705G (65W TDP) and the i7-8550U (15W TDP), highlighting a major performance difference despite both having 4 cores and 8 threads. The i7-8705G, paired with AMD Radeon RX Vega M GL graphics, serves as a high-performance option, while the i7-8550U uses integrated Intel UHD 620 for efficiency. In benchmark testing, the i7-8705G outperformed the i7-8550U by approximately 24% in 3D rendering and 7% in Photoshop, highlighting its superior processing power and graphical capabilities (pros), though it requires higher power consumption and robust cooling (cons). Conversely, the i7-8550U offers extreme efficiency for thin, light designs (pros), but suffers from lower sustained performance and vastly inferior graphics (cons). LaptopMedia concludes that the i7-8705G is the overall winner for performance-driven tasks, while the i7-8550U is better suited for users prioritizing battery life and portability.

The 2018 HP Spectre x360 15, featuring Intel’s Kaby Lake-G processor (Core i7-8705G with AMD Radeon RX Vega M graphics), acts as a high-performance 2-in-1 that bridges the gap between convertibles and workstations. This configuration provides superior processing power, roughly 50% faster than its Kaby Lake-R sibling in specific tasks, enabling strong, workstation-like performance in multi-core benchmarks. The design features an angled "Dark Ash Silver" aesthetic with a 15.6-inch 4K display and a full numeric keypad, offering a sturdy, "business-class" typing experience. However, the machine is relatively heavy at 4 pounds 10 ounces and the 84Wh battery life is strained by intensive tasks, despite decent endurance in mixed use. Key advantages include its excellent performance and robust port selection (Thunderbolt 3, HDMI), while the main trade-offs are the weight and moderate 4K display brightness compared to competitors.
