Intel Core i7 7740X Avis | 78 Données comparées

The Intel Core i7-7740X, reviewed by HardwareZone, is identified as a "fast but awkward" processor that places quad-core Kaby Lake architecture onto the HEDT X299 platform. Featuring a 4.3GHz base and 4.5GHz boost clock, it excels in single-threaded tasks, gaming, and responsiveness, while trailing in heavy multi-threaded workloads. Pros include high-speed performance and strong overclocking potential, with the chip reaching over 5GHz, whereas cons focus on its high cost and lack of platform features, such as limited PCIe lanes and dual-channel memory, on a premium motherboard. Ultimately, the review concludes the i7-7740X offers poor value compared to the cheaper Z270-based i7-7700K, acting as an uncomfortable middle-child in the CPU market.

Hardware Canucks characterizes the Intel Core i7-7740X as a misplaced "orphan" in the HEDT lineup, essentially a die-transplant of the mainstream i7-7700K onto the LGA 2066 socket that lacks key X299 platform features. While offering a slight 100MHz clock speed boost, the four-core, eight-thread chip is deemed underwhelming for high-end, despite offering a lower entry cost into the X299 ecosystem. The primary advantages highlighted are exceptional overclocking performance, with testers achieving a stable 5.1GHz on air cooling due to improved heat dissipation, making it suitable for high-frequency gaming. However, major drawbacks include limited PCIe lanes (16), reduced memory channels (dual-channel), and the lack of integrated graphics, rendering it,,, for most users, a pointless purchase over the cheaper i7-7700K and Z270 platform, as concluded by Hardware Canucks.

The TweakTown review identifies the Intel Core i7-7740X as a "transplanted" Kaby Lake CPU, offering a 4.3GHz base clock (100MHz over the i7-7700K) but moving to the X299 platform with a higher 112W TDP. Pros include exceptional overclocking (stable 5.1GHz at 1.3V), a "dream" for overclockers, and excellent single-threaded performance that excels in gaming. However, cons center on the platform restriction to dual-channel memory and only 16 PCIe lanes, while losing the integrated GPU found in the 7700K. The 7740X represents a niche "placeholder" for entering the X299 ecosystem with future upgrade paths, but it is difficult for the average user to justify over a standard i7-7700K given the higher total platform cost.

KitGuru’s review characterises the Intel Core i7-7740X as a "re-packaged," high-frequency 4-core/8-thread chip for the X299 platform, offering a slight 4.3GHz base clock boost over the i7-7700K but lacking integrated graphics. While demonstrating "tremendous" overclocking potential to 5.1GHz, the CPU suffers from poor value due to high platform costs, with performance lagging behind, or only equaling, cheaper alternatives in multi-threaded tasks. Ultimately deemed a niche option for competitive overclockers or as an X299 stepping stone, the review highlights the ironic, "awful" value proposition of a quad-core on a high-end, feature-restricted motherboard. Key Pros: Excellent 5.1GHz+ overclocking, superior single-core performance, and a path to HEDT upgrades. Key Cons: Poor overall value, high X299 platform costs for limited CPU features, and lack of integrated graphics.

The Guru3D review finds the Intel Core i7-7740X is a high-frequency, quad-core Kaby Lake-X processor offering exceptional overclocking capabilities up to 5.2 GHz, acting as an entry-level option for the X299 platform. While delivering strong gaming and single-threaded performance, the chip is hampered by high power consumption and significant heat output under load. The review notes that the expensive X299 platform requirement, combined with a lack of integrated graphics and limited dual-channel memory, makes the 7740X a niche product with questionable value compared to the similar-performing Core i7-7700K on the cheaper Z270 platform.

Tom's Hardware review finds the Intel Core i7-7740X is a 4-core, 8-thread "die transplant" on the HEDT X299 platform, offering high clock speeds and excellent overclocking capacity. However, it hamstrings the platform by offering only dual-channel memory support and limited PCIe lanes, while utilizing standard thermal paste that results in high temperature deltas. Lacking an integrated GPU and providing negligible performance gains over the cheaper Core i7-7700K, the i7-7740X is ultimately deemed a "pointless" entry point that fails to justify its total platform cost.

The PCMag review characterizes the Intel Core i7-7740X as a high-clock-speed (4.3GHz base, 4.5GHz turbo) "Kaby Lake-X" processor that serves as an entry point into the enthusiast X299 platform, offering excellent 1080p gaming performance. While it provides a potential upgrade path to higher-core CPUs, it functions essentially as a repackaged, slightly faster Core i7-7700K. Key disadvantages noted include the chip's restriction to 16 PCI Express lanes and dual-channel memory, which underutilizes the advanced features of X299 motherboards. Furthermore, it lacks integrated graphics and offers questionable value compared to competitors and its own mainstream counterparts, according to the review. Productivity benchmarks reveal performance nearly identical to the cheaper i7-7700K, though the chip shows good overclocking potential, reaching 4.8GHz to 5.1GHz in testing. The final verdict suggests this CPU is only suited for those needing a placeholder for a future X299 powerhouse build, recommending mainstream alternatives or higher-core X-series chips instead.

The Guru3D review of the Intel Core i7-7740X (Kaby Lake-X) processor on the X299 platform examines its position as a high-frequency, quad-core chip in the HEDT market. Pros include exceptional overclocking, with stability achieved at 5.2 GHz, and a solid upgrade path for the X299 platform. However, cons include high thermal output requiring premium cooling, and limitations on the X299 platform, such as disabled features like quad-channel memory.

The Intel Core i7-7740X is a quad-core Kaby Lake-X processor for the LGA 2066 platform, offering slightly higher clocks (4.3 GHz base, 4.5 GHz boost) than the i7-7700K but lacking an integrated GPU and restricting users to dual-channel memory. The review highlights excellent overclocking potential, reaching 5.2 GHz easily, along with better thermal management and lower operating temperatures under load compared to the 7700K. However, the i7-7740X suffers from poor value, forcing a more expensive X299 motherboard while crippling platform features, leading to a recommendation for the more capable 6-core i7-7800X instead.

HotHardware’s review of the Intel Core i9-7900X and Core i7-7740X features the Skylake-X flagship and Kaby Lake-X entry-level chip, launched to counter AMD's competition. The 10-core i9-7900X shines in multi-threaded tasks like rendering (Cinebench, Blender) with high clock speeds and quad-channel memory, though it requires heavy cooling due to high power consumption. Conversely, the i7-7740X offers high overclocking potential but lacks competitive value, as it is limited to dual-channel memory and 16 PCIe lanes, making it an awkward fit for the X299 HEDT platform.

The KitGuru review highlights the Intel Core i7-7740X as an ultra-fast gaming processor that essentially functions as a re-packaged 7700K for the X299 platform, offering exceptional single-core performance but lacking the benefits of quad-channel memory. While the chip demonstrates tremendous overclocking headroom, hitting a stable 5.1GHz across all cores, its high-power draw results in poor efficiency. Ultimately, due to high platform costs, limited PCIe lanes (16), and the lack of an integrated GPU, the 7740X is considered a niche product with questionable value compared to cheaper alternatives.
