Intel Core i5 7400 Review | 78 Data compared

The Intel Core i5-7400 is a 14nm Kaby Lake quad-core processor (3.0–3.5 GHz) with a 65W TDP, utilizing Intel HD Graphics 630 to support basic tasks. Released in 2017, this mid-range chip offers solid single-core performance, excellent thermal efficiency under load, and serves as a cost-effective choice for budget gaming with titles like CS:GO or League of Legends. Despite these strengths, the 4-core/4-thread design lacks hyper-threading, resulting in poor performance in multi-threaded tasks, potential stuttering in modern AAA games, and a lack of official Windows 11 support.

The Intel Core i5-7400 is a 7th Generation (Kaby Lake) 14nm desktop processor featuring four cores, four threads, and a base clock of 3.00 GHz, with max turbo frequencies up to 3.50 GHz. It provides reliable performance for basic tasks and esports, with the benefit of an efficient 65W TDP and Intel HD Graphics 630. However, it lacks Hyper-Threading, hindering performance in modern, multi-core optimized games, and is not officially supported for Windows 11, limiting its long-term viability.

The TechSpot review identifies the AMD Ryzen 5 1400 as a strong, budget-friendly, quad-core processor that excels in multi-threaded tasks, outperforming the Intel Core i5-7400 by 26% in Cinebench R15. A major pro is its unlocked multiplier, allowing for a 3.9–4.0 GHz overclock, though it suffers from a 10% deficit in single-threaded performance. In gaming, the 1400 delivers competitive minimum frame rates but is held back by a 8MB L3 cache, which is half that of the 1500X, resulting in lower peak performance. The processor is lauded for its high energy efficiency and cool operation, rarely exceeding 50°C during gaming, making it a "phenomenal value" for budget systems. However, a notable con is the requirement of a dedicated GPU due to the lack of integrated graphics. Ultimately, TechSpot recommends it for users prioritizing productivity and value over raw gaming performance. Copy

The Tom's Hardware review hails the Intel Core i5-8400 as a mid-range "game changer," introducing a six-core design to the i5 series with exceptional value at a 14nm process. Performance-wise, it is deemed a "pound-for-pound gaming champion" that matches or beats the previous flagship i7-7700K in many titles, providing a 40% to 54% boost over the i5-7400 in certain games. Key pros include high IPC, included cooling, and class-leading gaming value, though it is limited by a locked multiplier (no overclocking) and requires new, currently expensive Z370 motherboards. Furthermore, while excellent for gaming, its lack of Hyper-Threading allows it to fall behind AMD alternatives in heavy workstation tasks. For the full, detailed review, visit Tom's Hardware.

The Tom's Hardware review characterizes the Intel Core i5-8400 as a "pound-for-pound gaming champion," highlighting its six-core, non-hyper-threaded design that delivers top-tier performance for mid-range gaming systems. Pros include exceptional value, high gaming frame rates, and low power consumption, while the primary cons are its locked multiplier preventing overclocking and, at the time, a dependency on expensive Z370 motherboards. Despite limited multi-threaded prowess compared to competitors like the Ryzen 5 1600, it excelled in gaming and lightly-threaded tasks at a competitive price point.

TechSpot's review indicates that the overclocked Intel Core i3-7350K can outperform the i5-7400 by 3-5% in specific, less thread-intensive titles like Overwatch and Gears of War 4, showcasing the "pro" of high single-threaded performance. However, a significant "con" is its struggle in heavily multi-threaded games like Battlefield 1 and Watch Dogs 2, where the i3 fails to exceed or only matches the i5-7400's stock performance. Furthermore, the i3-7350K requires expensive Z-series motherboards and aftermarket cooling, whereas the Core i5-7400 provides more stable, consistent performance across varied workloads at a better value.

This TechSpot review compares mainstream Intel Core i3 and i5 processors, highlighting a significant performance gap driven by the i5’s four physical cores and higher Turbo Boost frequencies, which offer a substantial advantage in multi-threaded tasks like video editing and gaming. While the i5 boasts larger L3 cache and superior multitasking capability, its higher cost and power consumption are key cons, contrasting with the i3’s efficiency. Ultimately, for demanding gaming, the i5 provides higher, more stable frame rates, whereas the i3 is best suited for budget-conscious, basic productivity, offering a cost-effective but less capable alternative.

The TechSpot review identifies the ASUS ROG GR8 II as a capable, 4-liter, console-sized PC delivering strong 1080p gaming performance via a Core i7-7700 and GTX 1060 3GB, consistently hitting 60 FPS on high settings in demanding titles. While compact and easily upgradeable for storage and RAM, the system's longevity is capped by non-upgradeable CPU/GPU components. A major drawback noted is the loud, high-pitched fan noise under load, alongside an aesthetic deemed too aggressive by the reviewer. For more details, visit TechSpot. Copy

The Zhaoxin KX-U6780A represents a significant step in China's pursuit of x86 semiconductor self-sufficiency, utilizing TSMC’s 16nm process, eight cores, and a 2.7 GHz clock speed. A major pro is its native x86-64 compatibility, allowing it to run standard Windows and Linux, though it falls far behind Western counterparts in raw performance. While demonstrating moderate multi-threaded capabilities, the chip suffers from poor single-threaded performance and an aging architecture that lacks L3 cache. 电子工程世界（EEWorld） Performance analysis reveals the 70W TDP chip often underperforms compared to entry-level AMD and Intel processors in daily tasks, despite its eight-core design, and suffers from low power efficiency under load. Cons include a "woeful" single-threaded experience and a restricted BIOS, limiting its effectiveness for mainstream consumer use. Copy

TechSpot's analysis of CPU and GPU pairing, specifically at 1080p, demonstrates that mismatched components create significant performance bottlenecks, rendering high-end GPUs underutilized when paired with entry-level processors. The review highlights that while a "balanced" system is crucial for value, a CPU bottleneck is more problematic than a GPU bottleneck, as it causes severe stuttering and inconsistent frame times rather than just lower average frame rates. A key pro of this testing is identifying the "weakest link" to optimize hardware spending, though a con is that these findings are less applicable at higher resolutions, such as 1440p or 4K, where the workload shifts heavily to the GPU.

The TechSpot review highlights the Ryzen 3 1300X and 1200 as budget-friendly, four-core alternatives to dual-core processors, offering improved minimum frame rates in modern titles. A major advantage is the unlocked multiplier, enabling the 1200 to match higher-tier CPUs when overclocked, aided by an efficient, quiet Wraith Stealth cooler. Conversely, the lack of simultaneous multi-threading (SMT) results in lower performance in heavily threaded games, while the $20 premium for the 1300X offers diminishing returns over the overclockable 1200.
