Architecture Differences

Both processors belong to Intel's Core 14th Gen series and use the Raptor Lake architecture with the Raptor Lake-R codename. Intel fabricates both on a 10 nm process node at its own foundry. The two chips share the same Intel Socket 1700 interface and a 65 W TDP, but the internal layouts diverge significantly.

The Core i5-14400F uses 10 cores and 16 threads. The Core i7-14701E uses 8 cores and 16 threads. This means the i5-14400F has two more physical cores, while the i7-14701E relies on higher clock speeds to match thread counts. The i5-14400F has a base clock of 2.50 GHz and a boost clock of 4.70 GHz. The i7-14701E starts at 2.60 GHz and boosts to 5.40 GHz, a 0.70 GHz advantage at peak frequency.

Cache configurations differ substantially. Both allocate 80 KB of L1 cache per core, but the L2 cache per core is 1.25 MB on the i5-14400F versus 2 MB on the i7-14701E. The shared L3 cache is 20 MB on the i5-14400F and 33 MB on the i7-14701E. The i7-14701E also uses a larger physical die at 257 mm² compared to 215 mm² for the i5-14400F.

The Core i7-14701E includes UHD Graphics 770 integrated graphics. The Core i5-14400F has no integrated graphics unit, which explains the "F" suffix in its name. Both processors support PCIe Gen 5 with 16 lanes from the CPU. Both have locked multipliers, preventing manual overclocking. The i5-14400F carries the part number SRN3RSRN47, while the i7-14701E uses Q49FSRNJK.

Head-to-Head Benchmarks

The benchmark data paints a split picture. The Core i7-14701E wins 12 of the 17 recorded tests, but the Core i5-14400F takes the remaining 5, and those wins are often by large margins.

The most one-sided results favor the Core i7-14701E. In Passmark's find prime numbers test, the i7-14701E delivers 176 points against 86 for the i5-14400F, a 51.1% advantage. This is the largest delta in the entire comparison. Passmark physics shows a 36.5% lead for the i7-14701E, with scores of 2399 and 1523 respectively. Single-thread performance also clearly favors the i7-14701E: its 4305 Passmark single-thread score beats the i5-14400F's 3701 by 14%. The same pattern repeats in Cinebench single-core tests, where the i7-14701E leads by 2.5% in R15 (315 versus 307), 2.4% in R20 (1315 versus 1283), and 2.5% in R23 (3133 versus 3055).

Multi-core rendering tests follow the same direction. The i7-14701E scores 2237 in Cinebench R15 multi-core versus 2181, 9321 in R20 multi-core versus 9090, and 22195 in R23 multi-core versus 21645. Each of these wins is a consistent 2.5% margin. The Passmark multithread test shows 26112 for the i7-14701E versus 25470 for the i5-14400F, also a 2.5% difference. Floating point math goes to the i7-14701E by a narrow 0.9% (61873 versus 61319).

The Core i5-14400F takes its wins in specific workloads. Data encryption shows the biggest advantage at 14%: 16949 versus 14862. Random string sorting follows at 12.1% (32680 versus 29158). Data compression delivers an 11.5% lead (315521 versus 282939). Extended instructions favor the i5-14400F by 7.6% (19937 versus 18528). Integer math is nearly even, with the i5-14400F ahead by just 0.2% (81524 versus 81325).

The overall win count is lopsided, but the distribution of wins matters. The i7-14701E dominates in physics, prime number calculation, and single-threaded tests. The i5-14400F excels in data-focused workloads like compression, encryption, and string sorting.

L2 cache per core is 1.25 MB on the i5-14400F versus 2 MB on the i7-14701E. L3 cache is 20 MB shared on the i5-14400F versus 33 MB shared on the i7-14701E. Die size is 215 mm² for the i5-14400F and 257 mm² for the i7-14701E.

Integrated graphics represent a clear split. The i5-14400F has no iGPU. The i7-14701E includes UHD Graphics 770. The launch MSRP for the i5-14400F is $196. No launch MSRP is recorded for the i7-14701E. The release dates differ: the i5-14400F launched on 2024-01-07, while the i7-14701E launched on 2024-06-30.

Both processors share the same TDP of 65 W, the same Intel Socket 1700, the same 10 nm process node, the same foundry, the same DDR4 and DDR5 memory support, the same dual-channel memory bus, the same ECC memory support, the same PCIe Gen 5 with 16 CPU lanes, and locked multipliers. Both are classified as active production desktop parts.

Where Each One Wins

The Core i7-14701E is the stronger choice for single-threaded and physics-driven workloads. Its 14% lead in Passmark single-thread performance and 36.5% lead in Passmark physics point to advantages in applications that depend on high clock speeds and per-core efficiency. The 51.1% lead in find prime numbers reinforces this pattern. The consistent 2.5% wins across all Cinebench multi-core tests also mean the i7-14701E handles rendering tasks slightly better, despite having fewer physical cores. Its 5.40 GHz boost clock and larger 33 MB L3 cache support this result.

The Core i5-14400F wins where data throughput and specialized instruction execution matter. Its 14% advantage in data encryption, 12.1% advantage in random string sorting, and 11.5% advantage in data compression show that its 10-core layout handles parallel data manipulation tasks more efficiently. The 7.6% lead in extended instructions suggests an edge in workloads that use advanced CPU instruction sets. The near-tie in integer math (0.2% in favor of the i5-14400F) means neither chip has a meaningful edge in that category.

The i7-14701E also provides integrated graphics through UHD Graphics 770, which matters for systems that need display output without a discrete GPU. The i5-14400F requires a separate graphics card for any video output.

The Verdict

The benchmark data shows two processors with the same thread count and TDP but different strengths. The Core i7-14701E wins the majority of tests, including all Cinebench benchmarks and the Passmark multithread, physics, single-thread, floating point, and prime number tests. Its average benchmark score of 33206 is 2.9% higher than the i5-14400F's 32279. The i7-14701E also offers UHD Graphics 770 and a larger 33 MB L3 cache, which explains part of its performance edge in cache-sensitive workloads.

The Core i5-14400F is not simply a weaker chip. It wins 5 tests, and its victories in data compression, encryption, string sorting, and extended instructions are substantial, ranging from 7.6% to 14%. Its 10 physical cores give it an advantage in certain parallel data workloads, and its 215 mm² die is smaller, which can matter for thermal density.

The data suggests a straightforward split. For users prioritizing single-thread speed, physics simulation, prime number calculation, or general multi-core rendering, the Core i7-14701E is the better processor based on the recorded benchmarks. For users running data compression, encryption, or string-heavy workloads, the Core i5-14400F delivers measurable wins. The i7-14701E's higher average score and greater number of wins make it the stronger all-around processor in this comparison, but the i5-14400F holds clear territory in specific data-processing tasks.
