Intel Core i5-7400T

The Intel Core i5-7400T is a 4-core, 4-thread desktop processor built on the Kaby Lake architecture at 14 nm. It runs at a base clock of 2.40 GHz and boosts to 3.00 GHz, with a 35 W TDP. The chip integrates HD 630 graphics and supports DDR4 memory in dual-channel configuration. Its average benchmark score of 1354 places it in the 37th percentile of all CPUs, indicating a modest performance tier relative to the broader processor landscape.

Platform and Compatibility

The i5-7400T uses the Intel Socket 1151 interface, placing it within the Kaby Lake family manufactured on a 14 nm process. This is a desktop-market part, and its production status is listed as Active, meaning it remains a current offering. The processor supports DDR4 memory in a dual-channel layout, with a memory bandwidth of 38.4 GB/s. ECC memory is not supported, so the chip is aimed at mainstream consumer builds rather than server or workstation configurations that require error-correcting memory.

PCIe connectivity is provided via Gen 3 with 16 lanes available from the CPU. This is sufficient for a single high-bandwidth graphics card or multiple NVMe drives, though the exact lane allocation is not detailed in the data. The integrated graphics solution is the HD 630, which handles display output and basic acceleration without a discrete GPU. The multiplier is locked, preventing user overclocking, and the TDP is a modest 35 W, making the chip suitable for compact or low-power systems where thermal and power constraints are a priority. The socket 1151 platform itself is the physical foundation for this generation, though the FACT PACK does not specify which other processors share this socket.

Who Should Consider It

Benchmark results indicate that the i5-7400T is a competent processor for everyday computing tasks, but it does not excel in heavily threaded workloads. The Cinebench R23 multi-core score of 4016 and Geekbench multi-core score of 2836 reflect the limitations of a 4-core/4-thread design. For office productivity, web browsing, and light multitasking, the single-core performance, Cinebench R23 single-core score of 567 and Geekbench single-core score of 1026, provides adequate responsiveness, especially given the 3.00 GHz boost clock. The 35 W TDP makes the chip an excellent fit for small form factor builds, home theater PCs, or always-on systems where energy efficiency is valued.

Users who require heavy multi-threaded rendering, video encoding, or complex simulations will likely find the i5-7400T insufficient, as its 37th percentile standing among all CPUs suggests it sits in the lower half of the performance spectrum. The processor is best suited to users who prioritize low power consumption and adequate single-threaded speed over raw multi-core muscle. Gamers pairing this CPU with a mid-range discrete GPU can expect playable frame rates in less demanding titles, though the data does not include gaming-specific benchmarks. For content creators running batch operations or compiling large projects, the 4-thread ceiling will be a bottleneck.

How It Compares

The i5-7400T sits in a tightly clustered group of rivals, all within a 9-point range of its 1354 average benchmark score. The nearest competitor, the Intel Core i5-4670, averages 1351, giving the i5-7400T a 0.2% advantage. This is a negligible difference, effectively a tie in real-world performance. The i5-4670 is a Haswell-era quad-core without hyper-threading, and the data shows the two chips are interchangeable in aggregate workload performance.

Against the Intel Core i7-3720QM, a mobile quad-core with hyper-threading, the i5-7400T is 0.4% slower (average score 1359). The i7-3720QM’s higher multi-threaded capability is offset by its lower clock speeds and older architecture, resulting in near-identical overall performance. Similarly, the Intel Xeon E3-1226 v3 and Intel Xeon W-2104 both average 1360, each 0.4% ahead of the i5-7400T. These Xeon parts are server-oriented but share similar core/thread counts and clock ranges. In all four comparisons, the delta is less than half a percent, meaning the i5-7400T delivers performance statistically indistinguishable from these alternatives in the benchmarks recorded.

Benchmark Performance

The benchmark suite for the i5-7400T spans multiple versions of Cinebench and Geekbench. In Cinebench R15, the multi-core score is 404 and the single-core score is 57. The R20 iteration yields 1686 multi-core and 238 single-core, while R23 shows 4016 multi-core and 567 single-core. Geekbench results are 2836 multi-core and 1026 single-core. These numbers collectively produce an average benchmark score of 1354.

The single-core scores are notably lower than modern high-end parts, but they are consistent with the 3.00 GHz boost clock and the Kaby Lake architecture. The multi-core scores are constrained by the 4-thread design; for comparison, the nearest rival, the Intel Core i5-4670, has an average score of 1351, which is 0.2% lower than the i5-7400T. The i5-7400T trails the Intel Core i7-3720QM by 0.4% (1359 vs. 1354), the Intel Xeon E3-1226 v3 by 0.4% (1360 vs. 1354), and the Intel Xeon W-2104 by 0.4% (1360 vs. 1354). These deltas are so small that they fall well within normal run-to-run variation for synthetic benchmarks.

The 37th percentile ranking against all CPUs underscores the chip’s mid-low position in the overall performance hierarchy. While the i5-7400T is not a performance leader, its low TDP and integrated graphics make it a practical choice for basic desktop tasks. The benchmark data shows that it trades blows with older quad-core parts from both Intel’s desktop and mobile lineups, as well as entry-level Xeon processors. For users upgrading from a dual-core or an older quad-core, the i5-7400T offers a modest but measurable step forward, provided the workload is not heavily multi-threaded. The consistent sub-0.5% differences against all four rivals indicate that within this performance class, the i5-7400T is a solid, if unremarkable, contender.
