Intel Core 9 273PTE vs Intel Core i5-14400T Comparison

The Verdict

The Intel Core 9 273PTE is the dominant processor in this comparison. The recorded data shows it wins 15 of the 17 head-to-head benchmark comparisons, with the Intel Core i5-14400T taking only 2 wins. The Core 9 273PTE delivers a consistent 18.9% advantage across the Cinebench R15, R20, and R23 multicore tests, with the single-core R20 result reaching a 19.1% lead. Its average benchmark score of 31143 places it in the 82nd percentile of all CPUs, while the i5-14400T sits at 27166 and the 79th percentile.

The Core 9 273PTE is the choice for compute-heavy workloads, particularly those that scale with thread count. The data shows its passmark find prime numbers score is 94.5% higher than the i5-14400T, and the physics test shows a 54.1% advantage. The i5-14400T does hold one meaningful edge: a 2.2% higher passmark single-thread score, which suggests it can win in lightly threaded tasks that respond to raw per-core speed. However, that single victory does not offset the Core 9 273PTE's broad lead, especially since the Cinebench single-core tests favor the Core 9 273PTE by 18.9% to 19%.

Buyers who prioritize multicore throughput, encryption, integer math, or physics simulation should select the Core 9 273PTE. Those who run applications that are highly sensitive to a single thread and cannot use additional cores may find the i5-14400T acceptable, but the data indicates the Core 9 273PTE is the stronger all-around part.

Architecture Differences

The two processors come from different Intel design lineages. The Core 9 273PTE uses the Bartlett Lake codename and is listed under the Core 9 (Bartlett Lake) generation, while the i5-14400T uses the Raptor Lake-R codename and belongs to the Core i5 (Raptor Lake Refresh) generation. Both are built on a 10 nm process at Intel's foundry.

The core configurations differ substantially. The Core 9 273PTE has 12 cores and 24 threads, whereas the i5-14400T has 10 cores and 16 threads. That difference in thread count is the primary structural reason for the Core 9 273PTE's multicore advantage. The L1 cache is identical at 80 KB per core, but the L2 cache differs: the Core 9 273PTE has 2 MB per core, while the i5-14400T has 1.25 MB per core. The L3 cache also favors the Core 9 273PTE, with 36 MB shared versus 20 MB shared.

Both processors use the Intel Socket 1700, support DDR4 and DDR5 memory, and include UHD Graphics 730 integrated graphics. Both have PCIe Gen 5 with 16 lanes (CPU only). The i5-14400T has a known die size of 215 mm², while the die size for the Core 9 273PTE is not recorded in the database.

Specification Differences

The clock speeds differ in both directions. The Core 9 273PTE has a base clock of 1.40 GHz and a boost clock of 5.50 GHz. The i5-14400T has a higher base clock of 1.50 GHz but a lower boost clock of 4.50 GHz. The higher boost clock on the Core 9 273PTE aligns with its Cinebench single-core wins.

The thermal design power also differs. The Core 9 273PTE is rated at 45 W TDP, while the i5-14400T is rated at 35 W TDP. The Core 9 273PTE uses more power budget to support its additional cores and higher boost frequency.

Memory bandwidth figures are only recorded for the Core 9 273PTE, which lists 89.6 GB/s. The i5-14400T does not have a memory bandwidth value in the database.

The release dates are distinct. The i5-14400T was released on 2024-01-07, while the Core 9 273PTE was released on 2026-03-08. The launch MSRP for the Core 9 273PTE is $549, and the launch MSRP for the i5-14400T is $221.

Both processors are locked (multiplierUnlocked is false for each), so neither offers unlocked overclocking. Both are marked as Active production status and target the Desktop market segment. The part numbers differ: SA4QJ for the Core 9 273PTE and SRN3N for the i5-14400T.

Head-to-Head Benchmarks

The Core 9 273PTE wins every Cinebench test. In Cinebench R15 multicore, it scores 2060 against 1732, a 18.9% lead. The R15 single-core result is 290 versus 244, again 18.9%. The R20 multicore test shows 8586 versus 7219 (18.9%), and the R20 single-core test shows 1212 versus 1018, a 19.1% lead. The R23 multicore test shows 20445 versus 17189 (18.9%), and the R23 single-core test shows 2886 versus 2426, a 19% lead.

The passmark suite tells a similar story, but with larger deltas in some tests. The passmark integer math test shows 82411 versus 65667, a 25.5% advantage for the Core 9 273PTE. Floating point math shows 60673 versus 49139, a 23.5% lead. The find prime numbers test shows the largest gap: 142 versus 73, a 94.5% difference. The physics test also shows a major gap: 1917 versus 1244, a 54.1% lead.

The remaining passmark tests favor the Core 9 273PTE by smaller margins. Data compression shows 258704 versus 235636 (9.8%), data encryption shows 14253 versus 13244 (7.6%), extended instructions shows 15952 versus 14562 (9.5%), random string sorting shows 28973 versus 25181 (15.1%), and multithread shows 24054 versus 20223 (18.9%).

The i5-14400T wins only the two passmark single-thread tests. Both are listed with identical scores of 3512 versus 3433, a 2.2% advantage for the i5-14400T. This is the only benchmark category where the i5-14400T demonstrates superiority, and it does not appear in the Cinebench single-core results, where the Core 9 273PTE leads by roughly 19%.

Where Each One Wins

The Core 9 273PTE is the clear winner for multithreaded applications. Its 18.9% lead across all three Cinebench multicore tests and the passmark multithread test confirms that workloads using many threads will see a substantial performance uplift. The 25.5% advantage in integer math and the 23.5% advantage in floating point math make it the better choice for numerical computation, simulation, and data processing. The 94.5% lead in find prime numbers suggests an advantage in workloads that stress integer iteration and prime-number generation. The 54.1% lead in the physics test indicates stronger performance for physics simulation tasks.

The Core 9 273PTE also wins in data compression (9.8%), data encryption (7.6%), extended instructions (9.5%), and random string sorting (15.1%). These results indicate that the Core 9 273PTE is better suited for database workloads, compression utilities, and encryption-heavy applications.

The i5-14400T wins only in the passmark single-thread test, with a 2.2% margin. This suggests that in a narrow set of applications that cannot utilize multiple cores and rely on a single thread, the i5-14400T may perform slightly better. However, the Cinebench single-core results contradict this trend, showing the Core 9 273PTE ahead by 18.9% to 19%. The i5-14400T also has a higher base clock (1.50 GHz versus 1.40 GHz), which may help in short bursts of single-thread activity, but the Core 9 273PTE's higher boost clock (5.50 GHz versus 4.50 GHz) appears to dominate sustained single-core performance.

For users selecting between the two, the data points to the Core 9 273PTE for nearly every workload category. The i5-14400T is the better choice only for those who have verified that their primary application is bound by the specific passmark single-thread metric and cannot benefit from the Core 9 273PTE's additional cores, larger cache, and higher boost clock.
