Architecture Differences

The two processors share the same Intel Socket 1700 and are built on the same 10 nm process node at Intel's foundry, but their internal designs diverge significantly. The Core 9 273PQE uses the Bartlett Lake codename and is listed under the "Core 9 (Bartlett Lake)" generation, while the i5-14400 uses the Raptor Lake-R codename and belongs to the "Core i5 (Raptor Lake Refresh)" generation. The i5-14400 is explicitly labeled as Raptor Lake architecture, whereas the Core 9 273PQE has no architecture field filled in the database, only its codename.

The core configuration shows a clear difference: the Core 9 273PQE packs 12 cores and 24 threads, while the i5-14400 provides 10 cores and 16 threads. This translates to a 4-thread advantage for the Core 9, which directly impacts multi-threaded workloads. The L2 cache also differs, with the Core 9 offering 2 MB per core versus 1.25 MB per core for the i5-14400. The L3 cache is substantially larger on the Core 9 at 36 MB shared, compared to 20 MB shared for the i5-14400. Both use 80 KB of L1 cache per core.

Clock speeds favor the Core 9 273PQE significantly. Its base clock is 3.40 GHz with a boost clock of 5.90 GHz, while the i5-14400 runs at a 2.50 GHz base and 4.70 GHz boost. The power envelope also differs, with the Core 9 rated at a 125 W TDP versus 65 W for the i5-14400. The integrated graphics differ as well: the Core 9 includes UHD Graphics 770, while the i5-14400 ships with UHD Graphics 730. Both processors use the same PCIe Gen 5 with 16 CPU lanes, and neither has an unlocked multiplier.

The die size is only recorded for the i5-14400 at 215 mm², while the Core 9's die size is not listed. The Core 9 also reports a memory bandwidth of 89.6 GB/s, a figure not recorded for the i5-14400. The release dates place the i5-14400 earlier at January 2024, with the Core 9 following in March 2026.

Head-to-Head Benchmarks

The benchmark data shows a sweeping victory for the Core 9 273PQE across every recorded test, but the margins vary considerably by workload type. The Cinebench suite reveals remarkably consistent deltas. In R15 multicore, the Core 9 scores 3950 against 2148, a delta of 83.9%. The R15 single-core test shows 557 versus 303, an 83.8% delta. R20 multicore repeats the pattern at 83.9% (16459 versus 8952), and R20 single-core also hits 83.9% (2323 versus 1263). R23 multicore again lands at 83.9% (39190 versus 21315), while R23 single-core is slightly lower at 83.8% (5532 versus 3009). The consistency across all Cinebench versions suggests a uniform scaling advantage for the Core 9 in both threaded and single-threaded rendering tasks.

PassMark tests show a wider spread of deltas. The smallest margin is in single-thread performance, where the Core 9 scores 4573 versus 3741, a 22.2% delta. This indicates that while the Core 9 has a clear single-core clock and IPC advantage, it is far less pronounced than the multi-threaded gaps. The data compression test shows an 86% delta (585752 versus 314995), while data encryption shows 77.1% (29636 versus 16731). Extended instructions deliver a 95.5% delta (38743 versus 19816).

The largest deltas appear in computational math workloads. The find prime numbers test shows a 147.5% delta (198 versus 80), the highest of any benchmark in the comparison. Floating point math follows with a 104% delta (125546 versus 61549), and integer math shows 100.7% (164629 versus 82017). Physics tests show a 97.3% delta (2754 versus 1396). The multithread PassMark test records an 83.8% delta (46107 versus 25080), matching the Cinebench pattern. Random string sorting has the smallest multi-threaded margin at 64.4% (53167 versus 32346).

The data suggests that the Core 9's advantage grows with arithmetic intensity. Prime number finding, floating point, and integer math all show deltas above 100%, while more memory-bound or I/O-oriented tasks like string sorting show smaller gaps. The single-thread delta of 22.2% stands apart from the rest, showing that the Core 9's clock speed and architecture benefits are most pronounced when all cores are active.

The Verdict

The recorded data delivers a one-sided verdict. The Intel Core 9 273PQE wins all 17 head-to-head benchmark entries against the Intel Core i5-14400, with no countervailing wins for the i5. The average benchmark score difference is substantial: 66099 versus 32115, meaning the Core 9's average score is more than double that of the i5-14400. The percentile ranking confirms this, with the Core 9 at 93rd percentile versus 82nd for the i5.

The Core 9 273PQE is the clear choice for any workload where the database shows a performance requirement. The i5-14400's single-thread PassMark score of 3741 is closer to the Core 9's 4573, but still trails by 22.2%. In every multi-threaded test, the Core 9 leads by at least 64.4%, and in several math-focused tests, it leads by more than 100%. The i5-14400 does offer a lower TDP (65 W versus 125 W) and a smaller die size (215 mm² versus no recorded size for the Core 9), but the performance data shows no scenario in this benchmark set where the i5 comes out ahead.

The Core 9's higher core count (12 versus 10), larger L3 cache (36 MB versus 20 MB), and higher boost clock (5.90 GHz versus 4.70 GHz) all align with its benchmark dominance. For a user whose priority is raw performance as measured by these tests, the Core 9 273PQE is the only choice supported by the data. The i5-14400 may serve in configurations where its lower power draw is critical, but the benchmark results offer no performance justification for selecting it over the Core 9.

Specification Differences

The two processors differ in several key specification fields. The Core 9 273PQE has 12 cores and 24 threads, while the i5-14400 has 10 cores and 16 threads. Base clocks are 3.40 GHz for the Core 9 and 2.50 GHz for the i5-14400. Boost clocks are 5.90 GHz versus 4.70 GHz. TDP is 125 W for the Core 9 and 65 W for the i5-14400.

Cache configurations differ in L2 and L3. The Core 9 uses 2 MB of L2 per core, while the i5-14400 uses 1.25 MB per core. L3 cache is 36 MB shared on the Core 9, versus 20 MB shared on the i5-14400. Both share the same L1 cache size of 80 KB per core.

The integrated graphics differ: UHD Graphics 770 on the Core 9, UHD Graphics 730 on the i5-14400. Memory bandwidth is listed only for the Core 9 at 89.6 GB/s; the i5-14400 has no recorded value. The die size is listed only for the i5-14400 at 215 mm². Release dates differ, with the i5-14400 launching in January 2024 and the Core 9 in March 2026. The part numbers also differ (SA4Q9 for the Core 9, SRN3QSRN46 for the i5-14400).

Fields that are identical between the two include the socket (Intel Socket 1700), process node (10 nm), foundry (Intel), memory support (DDR4 and DDR5), memory bus (dual-channel), ECC memory support (true for both), PCIe configuration (Gen 5, 16 lanes CPU only), market segment (Desktop), production status (Active), and multiplier unlock status (false for both).

Where Each One Wins

The data shows the Core 9 273PQE winning in every benchmark category, but the size of the win varies and points to different workload strengths. In single-threaded performance, measured by PassMark single-thread and Cinebench R23 single-core, the Core 9 leads by 22.2% and 83.8% respectively. The PassMark single-thread delta is the smallest margin in the entire comparison, suggesting that the i5-14400 is comparatively less disadvantaged in lightly threaded applications. Still, the Core 9 takes the win.

For multi-threaded rendering workloads, the Cinebench suite shows a consistent 83.9% delta across R15, R20, and R23 multicore tests. This indicates that the Core 9's additional cores and threads translate directly into proportional gains in rendering tasks. The PassMark multithread test confirms this at 83.8%. The i5-14400's 10 cores and 16 threads are simply outmatched by the Core 9's 12 cores and 24 threads in these scenarios.

The largest wins for the Core 9 come in arithmetic and physics workloads. The find prime numbers test shows a 147.5% delta, floating point math a 104% delta, and integer math a 100.7% delta. Physics follows at 97.3%. These workloads appear to benefit disproportionately from the Core 9's higher clock speeds and larger cache. The extended instructions test also shows a strong 95.5% delta, indicating that SIMD-heavy code runs far better on the Core 9.

The smallest multi-threaded win for the Core 9 is in random string sorting at 64.4%, a memory-intensive task that shows the i5-14400 in its best relative light among threaded workloads. Data compression (86% delta) and data encryption (77.1% delta) fall in between. The i5-14400's only advantage is its lower TDP of 65 W versus 125 W, which could matter in power-constrained builds, but the benchmark data provides no performance scenario where the i5-14400 takes the lead. The Core 9 273PQE is the winner in every measured category.
