Intel Core 9 273PE vs Intel Core i5-14500HX Comparison

The Verdict

The benchmark data presents a clear hierarchy: the Intel Core 9 273PE wins every single head-to-head comparison against the Intel Core i5-14500HX, taking all 17 recorded tests. The average benchmark score gap is substantial, with the Core 9 273PE at 49845 versus 35094 for the i5-14500HX, a difference of roughly 42%. The Core 9 273PE sits in the 90th percentile of all CPUs, while the i5-14500HX lands in the 84th percentile.

Looking at the nearest rivals confirms the positioning. The Core 9 273PE trades blows with the AMD Ryzen AI Max+ 388 (0.1% ahead), the Intel Core i5-14600KF (0.9% ahead), the Intel Core i9-13980HX (1.1% behind), and the AMD Ryzen AI 9 HX PRO 370 (1.2% behind). The i5-14500HX, by contrast, sits in a lower performance tier, matching the Intel Core i9-12900HX (0.3% ahead), the Intel Core i7-13800H (0.3% ahead), the Intel Core 7 253PTE (0.4% ahead), and trailing the Intel Core i7-12700K by 0.5%. In short, the Core 9 273PE belongs to a higher performance class entirely, one populated by flagship desktop and high-end mobile parts, while the i5-14500HX competes in the upper-midrange mobile arena.

The choice depends entirely on the target platform and performance requirement. The Core 9 273PE is a desktop part on Intel Socket 1700 with a 65 W TDP, while the i5-14500HX is a mobile processor on Intel BGA 1964 with a 55 W TDP. The data shows the Core 9 273PE delivers consistently higher scores across every workload category, from single-threaded tasks to heavily parallel compute. The i5-14500HX, however, remains the only one of the two with an unlocked multiplier, which matters for systems where overclocking is the priority.

Where Each One Wins

The Core 9 273PE wins every benchmark in the comparison set, so the more useful question is where its advantage is largest and where it narrows to a near tie.

The largest margins appear in compute-heavy workloads. In PassMark physics, the Core 9 273PE scores 3120 against 1911 for the i5-14500HX, a 63.3% advantage. PassMark floating point math shows a 55.4% lead (107884 versus 69442), and passmark find prime numbers delivers a 56.2% gap (203 versus 130). Integer math follows closely at 45.9% (139410 versus 95584). These are workloads that scale with core count, thread count, and memory bandwidth, and the Core 9 273PE exploits all three.

The Cinebench suite shows a consistent 29.1% to 29.4% advantage across R15, R20, and R23, in both single-core and multi-core tests. This consistency suggests the architectural advantage of the Core 9 273PE is broad rather than workload-specific. The smaller wins come in PassMark single-thread tests, where the Core 9 273PE leads by just 0.6% (3650 versus 3629). That near-tie indicates the two processors have essentially equivalent single-threaded execution capability in this specific metric, despite the Core 9 273PE's higher boost clock of 5.70 GHz versus 4.90 GHz.

Data compression (21.6% ahead), random string sorting (24.5%), extended instructions (23%), and data encryption (16.5%) round out the middle tier of wins. The i5-14500HX has no benchmark where it takes the lead.

Architecture Differences

The two processors come from different Intel design families. The Core 9 273PE uses the Bartlett Lake codename and is classified under the Core 9 (Bartlett Lake) generation, while the i5-14500HX uses the Raptor Lake architecture with the Raptor Lake-HX codename and belongs to the Core i5 (Raptor Lake-HX Refresh) generation. Both are built on Intel's 10 nm process node and manufactured by Intel.

Core and thread configurations differ in an interesting way. The Core 9 273PE has 12 cores and 24 threads, while the i5-14500HX has 14 cores and 20 threads. The i5-14500HX has two more physical cores, but the Core 9 273PE has four more threads, indicating a different hybrid core arrangement. The Core 9 273PE's 2.30 GHz base clock is lower than the i5-14500HX's 2.60 GHz, but its 5.70 GHz boost clock is substantially higher than the 4.90 GHz boost of the mobile part.

Cache hierarchies also differ. Both use 80 KB of L1 per core and 2 MB of L2 per core, but the shared L3 cache is 36 MB on the Core 9 273PE versus 24 MB on the i5-14500HX. That 12 MB difference in last-level cache likely contributes to the Core 9 273PE's advantage in data-heavy workloads.

Memory support is identical in type: both support DDR4 and DDR5 with dual-channel memory buses and ECC memory. The Core 9 273PE lists a memory bandwidth of 89.6 GB/s, while the i5-14500HX record does not include a bandwidth figure. PCIe support matches as well: both use Gen 5 with 16 CPU lanes. Integrated graphics differ slightly, with the Core 9 273PE carrying UHD Graphics 730 and the i5-14500HX using UHD Graphics 770.

The market segments are opposite: the Core 9 273PE is a desktop part, while the i5-14500HX is a mobile processor. The Core 9 273PE launched on 2026-03-08 with a launch MSRP of $549. The i5-14500HX launched on 2024-01-07 and has no recorded launch MSRP in the database. The i5-14500HX has an unlocked multiplier, while the Core 9 273PE does not.

Head-to-Head Benchmarks

The head-to-head data shows a dominant sweep, but the margins tell a more nuanced story about workload scaling. The Cinebench suite produces remarkably uniform deltas. In Cinebench R15 multicore, the Core 9 273PE scores 3153 against 2442, a 29.1% lead. R15 singlecore shows 445 versus 344, a 29.4% gap. R20 multicore delivers 13140 versus 10178 (29.1%), R20 singlecore 1855 versus 1436 (29.2%), R23 multicore 31288 versus 24234 (29.1%), and R23 singlecore 4417 versus 3421 (29.1%). The narrow spread of these percentages, from 29.1% to 29.4%, indicates that the performance advantage is nearly constant across both single-threaded and multi-threaded rendering workloads.

PassMark results are far more variable. The smallest margin in the entire comparison is PassMark single-thread, where the Core 9 273PE scores 3650 versus 3629, a mere 0.6% difference. This near-parity suggests that in simple single-threaded execution, the two architectures are effectively matched, and the higher boost clock of the Core 9 273PE does not translate into a meaningful advantage in this particular metric.

The largest margins appear in physics and math workloads. PassMark physics shows the Core 9 273PE at 3120 versus 1911, a 63.3% advantage, the biggest delta in the entire head-to-head set. PassMark floating point math follows with 107884 versus 69442, a 55.4% gap. PassMark find prime numbers shows 203 versus 130, a 56.2% lead. PassMark integer math delivers 139410 versus 95584, a 45.9% advantage. These results point to the Core 9 273PE's superior multi-threaded throughput and possibly its larger 36 MB L3 cache.

Data-oriented workloads show mid-range deltas. PassMark data compression scores 405885 versus 333851, a 21.6% lead. Random string sorting shows 45098 versus 36219, a 24.5% gap. Extended instructions deliver 24630 versus 20019, a 23% advantage. Data encryption is the smallest of this group at 16.5% (22719 versus 19502). PassMark multithread scores 36810 versus 28508, a 29.1% lead that matches the Cinebench pattern.

The aggregate picture is unambiguous: the Core 9 273PE outperforms the i5-14500HX in all 17 recorded comparisons. The only near-tie is single-threaded PassMark, and even there the Core 9 273PE edges ahead. Every other workload shows a double-digit advantage, with several exceeding 50%.
