Intel Core i5-14400T vs Intel Core i7-14701E Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Core i7-14701E wins every single one of the 17 recorded head-to-head tests against the Intel Core i5-14400T. There are no tests where the i5-14400T takes the lead, and the margin is significant across both synthetic single-thread and multi-thread workloads.

In the Cinebench suite, the i7-14701E consistently delivers a 22.6% advantage in both single-core and multi-core tests. The Cinebench R23 multi-core score shows the i7 at 22195 versus the i5 at 17189, while the R23 single-core score is 3133 versus 2426. The same 22.6% delta appears in Cinebench R15 and R20 for both single-core and multi-core runs, indicating a uniform performance gap that scales across the entire Cinebench family.

The Passmark results show a broader range of deltas. The largest single gap is in the find prime numbers test, where the i7-14701E scores 176 versus the i5-14400T's 73, a 58.5% difference. The physics test also shows a substantial gap at 48.1%, with scores of 2399 and 1244 respectively. More moderate gaps appear in data encryption (10.9% delta, 14862 versus 13244) and random string sorting (13.6% delta, 29158 versus 25181). Data compression shows a 16.7% delta (282939 versus 235636), integer math a 19.3% delta (81325 versus 65667), and floating point math a 20.6% delta (61873 versus 49139). Extended instructions show a 21.4% delta (18528 versus 14562).

The Passmark multi-thread test shows the i7-14701E at 26112 versus the i5-14400T at 20223, a 22.6% delta that mirrors the Cinebench multi-core results. Single-thread Passmark scores are 4305 versus 3512, an 18.4% delta, slightly smaller than the Cinebench single-core gap.

The average benchmark score tells the same story. The i7-14701E has an average score of 33206, while the i5-14400T sits at 27166. The i7-14701E also holds a higher percentile ranking at 83 versus the i5-14400T's 79, meaning the i7 places in the top 17% of all CPUs in the database while the i5 places in the top 21%.

The Verdict

The data shows a clear hierarchy. The i7-14701E outperforms the i5-14400T in every recorded benchmark, with margins ranging from 10.9% to 58.5%. The i5-14400T has no benchmark wins to claim. For any workload that benefits from either single-thread speed or multi-thread throughput, the i7-14701E is the stronger choice based strictly on these measurements.

The i5-14400T does have a lower TDP at 35 watts versus 65 watts for the i7-14701E, which could matter for power-constrained builds. The i5 also launched at $221 (MSRP), while the i7-14701E has no recorded launch MSRP in the database. However, the performance gap is substantial enough that the i7-14701E is the default recommendation for anyone prioritizing compute performance. The i5-14400T remains a functional desktop processor, but the recorded data does not show any scenario where it wins.

Architecture Differences

Both processors are built on the same fundamental architecture. They share the Raptor Lake architecture with the Raptor Lake-R codename, belong to the Core 14th Gen series, and use the same 10 nm process node from Intel. Both have a desktop market segment designation and are currently listed as Active in production status.

The core configurations differ. The i5-14400T has 10 cores and 16 threads, while the i7-14701E has 8 cores and 16 threads. This means the i5 has two additional physical cores, but both have the same thread count. The thread parity combined with the i7's advantage in every benchmark indicates that the i7's higher clock speeds and larger cache more than compensate for its lower core count.

Cache allocation is notably different. The i5-14400T has 1.25 MB of L2 cache per core and 20 MB of shared L3 cache. The i7-14701E has 2 MB of L2 cache per core and 33 MB of shared L3 cache. Both have 80 KB of L1 cache per core. The i7's larger L2 and L3 caches likely contribute to its performance lead in cache-sensitive workloads.

The integrated graphics differ as well. The i5-14400T includes UHD Graphics 730, while the i7-14701E has UHD Graphics 770. Both support DDR4 and DDR5 memory in a dual-channel configuration, and both support ECC memory. PCIe capability is identical: Gen 5 with 16 lanes from the CPU.

The die size differs, with the i5-14400T at 215 mm² and the i7-14701E at 257 mm². The release dates are different: the i5-14400T was released on 2024-01-07, while the i7-14701E came later on 2024-06-30. Both use the Intel Socket 1700.

Specification Differences

The two CPUs differ in several specification fields. The i5-14400T has a base clock of 1.50 GHz and a boost clock of 4.50 GHz. The i7-14701E has a base clock of 2.60 GHz and a boost clock of 5.40 GHz. The i7's base clock is 1.1 GHz higher and its boost clock is 0.9 GHz higher.

TDP is another difference, with the i5-14400T rated at 35 watts and the i7-14701E at 65 watts. Core count differs as noted, with the i5 at 10 cores versus the i7 at 8 cores, while threads are equal at 16. L2 cache per core is 1.25 MB for the i5 and 2 MB for the i7, and L3 cache is 20 MB for the i5 and 33 MB for the i7. Die size is 215 mm² for the i5 and 257 mm² for the i7. The i5 has a recorded launch MSRP of $221, while the i7 has no launch MSRP in the database. The part numbers differ: SRN3N for the i5 and Q49FSRNJK for the i7. Release dates differ by about six months. The integrated graphics are different models. The generation field shows Core i5 (Raptor Lake Refresh) for the i5 and Core i7 (Raptor Lake Refresh) for the i7.

Where Each One Wins

The i7-14701E wins in every benchmark category recorded. The largest advantages are in prime number finding (58.5% delta) and physics (48.1% delta), suggesting workloads that stress integer operations and physics simulation will see the most dramatic gains. The smallest advantage is in data encryption at 10.9%, but it is still a win for the i7.

For multi-threaded productivity workloads such as video rendering, compilation, or 3D modeling, the i7-14701E delivers a consistent 22.6% lead over the i5-14400T in both Cinebench R23 multi-core and Passmark multi-thread tests. The i7's advantage in data compression (16.7%), integer math (19.3%), and floating point math (20.6%) reinforces its suitability for scientific computing and data processing tasks.

For single-threaded responsiveness, the i7-14701E leads by 18.4% in Passmark single-thread and 22.6% in Cinebench R23 single-core. This translates to faster application startup and better performance in lightly threaded applications. The i7's higher boost clock of 5.40 GHz versus 4.50 GHz is the likely driver of this single-thread advantage.

The i5-14400T does not win any benchmark in the database. Its only recorded advantages are structural, not performance-based: it has a lower 35 watt TDP versus 65 watts, two more physical cores, and a lower launch MSRP of $221. These factors could make it appealing for power-sensitive builds or systems where the additional physical cores are desired for thread scheduling reasons, but the recorded performance data does not show any workload where it outperforms the i7-14701E.

The i7-14701E's nearest rivals in the database are the AMD Ryzen 9 PRO 6950H (0% delta), AMD Ryzen 5 8645HS (0.1% delta), AMD Ryzen 7 7745HX (0.3% delta), and Intel Core i7-13650HX (0.4% delta). The i5-14400T's nearest rivals are the Intel Core i9-9900K (0.3% delta), AMD Ryzen 7 5700G (0.4% delta), Intel Core i7-13700H (0.7% delta), and AMD Ryzen 3 PRO 5355G (0.8% delta). The i7-14701E sits in a higher performance tier, with an average score about 6000 points higher than the i5-14400T.
