Intel Core i5-14400T vs Intel Core i7-12700H Comparison

The Intel Core i5-14400T and Intel Core i7-12700H sit in the same overall performance band, both landing in the 79th percentile versus all CPUs in the database, but the recorded data shows they get there in very different ways. The i7-12700H dominates the head-to-head record with 15 wins against 2 for the i5-14400T, yet the i5-14400T holds the two most striking victories: a 36.1% lead in Cinebench R23 single-core and a 5.4% edge in R23 multi-core. Average benchmark scores tell a similar story of near-parity, with the i5-14400T at 27166 and the i7-12700H at 26717. The database shows a matchup where one chip wins broadly, the other wins sharply.

Head-to-Head Benchmarks

Start with the sweep. The i7-12700H takes nearly every Passmark test in the record: integer math by 27.1% (90106 versus 65667), random string sorting by 24.7% (33449 versus 25181), data encryption by 24.6% (17575 versus 13244), floating point math by 24.5% (65075 versus 49139), prime finding by 22.3% (94 versus 73), data compression by 21.6% (300594 versus 235636), the overall multithread score by 21.1% (25615 versus 20223), extended instructions by 18.6% (17886 versus 14562), and physics by 17.7% (1512 versus 1244). That is a consistent, across-the-board advantage in sustained threaded and computational workloads, roughly in the 18 to 27% range.

Cinebench splits in an unusual way. The i7-12700H wins R15 multi-core by 33.5% (2604.6 versus 1732) and R20 multi-core by 19.1% (8921 versus 7219). It also takes R15 single-core by 4.7% and R20 single-core by the same 19.1% margin (1259 versus 1018). Then the picture flips hard in R23: the i5-14400T scores 17189 in multi-core against 16307.5 for the i7-12700H, a 5.4% win, and it wins single-core 2426 to 1782, a massive 36.1% gap. The database records a 644-point single-core advantage for the desktop part in the newest Cinebench generation in this set, which is the largest margin in either direction across the entire record.

Passmark single-thread is effectively a tie: 3535 for the i7-12700H against 3512 for the i5-14400T, a 0.7% difference. Given how the two chips trade Cinebench single-core results across versions, that near-dead heat suggests everyday lightly-threaded responsiveness is not a deciding factor between them.

Context from the rivals list reinforces how close these two are overall. The i5-14400T averages within 0.3% of the Intel Core i9-9900K, 0.4% of the AMD Ryzen 7 5700G, and 0.7% of the Intel Core i7-13700H. The i7-12700H sits within 0.1% of both the AMD EPYC 9554 and the AMD Ryzen 5 5500GT, and 0.3% ahead of the Intel Core i9-11900K. Both chips occupy the same neighborhood; the question is which workload profile fits your use case.

Where Each One Wins

The data points to a clear split. For sustained multi-threaded compute, the i7-12700H is the stronger recorded performer: compression, encryption, integer and floating point math, prime search, string sorting, and physics simulations all land 17.7% to 27.1% in its favor. Rendering in older Cinebench builds follows the same trend. If the workload runs many threads for long stretches, the 14-core, 20-thread i7-12700H is the pick per the data.

The i5-14400T wins where per-core speed dominates. Its 2426-point Cinebench R23 single-core score, 36.1% ahead, is the headline: older games and single-thread-bound applications favor it in that test. Its R23 multi-core win of 5.4% also shows the newer architecture holding up in the newest rendering benchmark in the record, even against the higher core count. Note that only the i7-12700H has 3DMark CPU data in the pack (6941 at max threads, 4951 at 8 threads, 3268 at 4 threads, 1817 at 2 threads, 949 single-thread), so gaming comparisons between the two cannot be drawn from this record.

There is also a practical platform angle visible in the spec data. The i5-14400T is a desktop socketed part on Intel Socket 1700, while the i7-12700H is soldered to BGA 1744, meaning it lives inside pre-built mobile systems. The i5-14400T also runs at a 35W TDP versus 45W for the i7-12700H, notable given the desktop chip still matches or beats it in the R23 tests.

FAQ

Q: Which CPU wins more benchmarks overall?

A: The Intel Core i7-12700H, with 15 wins against 2 for the Intel Core i5-14400T in the recorded head-to-head set.

Q: Which one is faster in single-core?

A: It depends on the test. The i5-14400T leads Cinebench R23 single-core by 36.1% (2426 versus 1782), while the i7-12700H leads R20 single-core by 19.1%, R15 single-core by 4.7%, and Passmark single-thread by a marginal 0.7%.

A: Both sit in the 79th percentile versus all CPUs. Average benchmark scores are 27166 for the i5-14400T and 26717 for the i7-12700H, a small gap in the desktop chip's favor.

Q: What integrated graphics does each have?

A: The i7-12700H has Iris Xe 96EU graphics; the i5-14400T has UHD Graphics 730.

Specification Differences

The two chips differ in nearly every headline spec. Core counts: 10 cores and 16 threads on the i5-14400T versus 14 cores and 20 threads on the i7-12700H. Clocks: the i5-14400T runs a 1.50 base and 4.50 boost, while the i7-12700H runs a 2.30 base and 4.70 boost. TDP is 35W versus 45W. The market segments differ, Desktop versus Mobile, and so do the sockets: Intel Socket 1700 versus Intel BGA 1744, meaning only the i5-14400T is a socketed, replaceable part.

Cache diverges at L3: 20 MB shared on the i5-14400T versus 24 MB shared on the i7-12700H, with identical L1 (80 KB per core) and L2 (1.25 MB per core). PCIe support differs in both generation and lane count: Gen 5 with 16 CPU lanes on the i5-14400T versus Gen 4 with 20 CPU lanes on the i7-12700H. ECC memory is supported only on the i5-14400T. Integrated graphics differ as noted above. Neither chip has an unlocked multiplier. The i5-14400T has a recorded launch MSRP of $221; no launch MSRP is recorded for the i7-12700H. Die sizes are close, 215 mm² versus 217 mm², and the i5-14400T has a recorded release date of January 2024.

Architecture Differences

Both chips come from Intel on a 10 nm process, but they represent different architectural generations. The i5-14400T is Raptor Lake, codename Raptor Lake-R, from the Core 14th Gen series. The i7-12700H is Alder Lake, codename Alder Lake-H, from the Core 12th Gen series and the mobile H-segment. Raptor Lake is the newer design, and that shows up directly in the Cinebench R23 results, where the i5-14400T wins both single-core and multi-core despite fewer cores, a lower TDP, and a lower boost clock.

The extra cores and threads of the Alder Lake-H part explain its broad Passmark dominance: 14 cores and 20 threads simply provide more throughput for integer math, compression, and encryption, and its 24 MB of shared L3 helps sustained workloads. The i5-14400T counters with newer cores, Gen 5 PCIe for faster peripheral connectivity on fewer lanes, and ECC support, a feature more commonly associated with workstation use. Both share the same memory controller characteristics, DDR4 and DDR5 on dual-channel, and neither allows multiplier overclocking.

The Verdict

Pick based on workload and platform needs. The data says the i7-12700H is the stronger all-round threaded performer, winning 15 of 17 head-to-head tests with margins up to 33.5% in Cinebench R15 multi-core and 27.1% in integer math. But it exists only as a soldered BGA mobile part, so it is chosen by buying a laptop that contains it, not by building around it.

The i5-14400T is the choice for a socketed desktop build where per-core speed matters. Its 36.1% single-core lead in Cinebench R23 and its 5.4% multi-core win in the same test show the newer architecture punching above its core count, and it does so at a 35W TDP. Add Gen 5 PCIe, ECC support, socketability, and the recorded launch MSRP of $221, and the database record supports it as the practical pick for upgradable desktops, while the i7-12700H remains the recorded performance leader for heavily threaded work in mobile form factors.
