Intel Core 9 273PE vs Intel Core i9-14900HX Comparison

The Verdict

The recorded data splits these two processors along clear workload lines. The Intel Core i9-14900HX wins 12 of the 17 head-to-head benchmarks, while the Intel Core 9 273PE takes 5. The average benchmark score for the i9-14900HX is 56004, which sits 12.4% above the 273PE's average of 49845. The i9-14900HX also holds the 91st percentile against all CPUs, one point higher than the 273PE's 90th percentile.

The Core 9 273PE is the choice for single-threaded Cinebench workloads. Its R23 single-core score of 4417 is 102.5% ahead of the i9-14900HX's 2181.5, and its R15 single-core score of 445 beats the i9-14900HX's 310.5 by 43.3%. The 273PE also wins in prime number finding (5.2% ahead) and physics simulation (18.3% ahead). These results point to a desktop part that handles lightly threaded and latency-sensitive tasks with more authority.

The Core i9-14900HX dominates the heavier throughput tests. It leads by 31.1% in R15 multi-core, 15.9% in R20 multi-core, 24.8% in data compression, 30.4% in data encryption, 21.2% in extended instructions, and 25.9% in random string sorting. The mobile chip's 24 cores and 32 threads give it a structural advantage in parallel workloads, even though both processors share the same 36 MB of L3 cache and 10 nm process node.

Architecture Differences

The two processors come from different Intel families. The Core 9 273PE uses the Bartlett Lake codename and belongs to the Core 9 generation, while the Core i9-14900HX uses Raptor Lake and sits in the Core 14th Gen series. Both are built on Intel's 10 nm process, but their physical designs diverge sharply.

The 273PE is a desktop part with 12 cores and 24 threads, a base clock of 2.30 GHz, and a boost clock of 5.70 GHz. It uses the Intel Socket 1700 and has a 65 W TDP. The i9-14900HX is a mobile processor with 24 cores and 32 threads, a base clock of 2.20 GHz, and a boost clock of 5.80 GHz. It uses the Intel BGA 1964 socket and carries a 55 W TDP. The i9-14900HX has a die size of 257 mm². The 273PE lists no die size in the database.

Cache configurations are identical: both have 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. Both support DDR4 and DDR5 memory over a dual-channel bus, and both support ECC memory. The 273PE lists a memory bandwidth of 89.6 GB/s, while the i9-14900HX does not have a recorded bandwidth figure. Both use PCIe Gen 5 with 16 CPU-only lanes.

Integrated graphics differ. The 273PE carries UHD Graphics 730; the i9-14900HX carries UHD Graphics 770. The i9-14900HX has an unlocked multiplier, while the 273PE does not. The 273PE launched with an MSRP of $549; the i9-14900HX has no recorded launch MSRP. Both processors are active in production. The 273PE's release date is March 2026, while the i9-14900HX's is January 2024.

Head-to-Head Benchmarks

The biggest single-core gap appears in Cinebench R23. The 273PE scores 4417 versus 2181.5 for the i9-14900HX, a 102.5% advantage. This is the largest delta in the entire benchmark set. The R15 single-core test shows a similar pattern, with 445 versus 310.5, a 43.3% lead for the 273PE. Interestingly, the R20 single-core test reverses direction: the i9-14900HX scores 2204 against 1855, a 15.8% lead.

Multi-core results are mostly in the i9-14900HX's favor, but not uniformly. The i9-14900HX leads R15 multi-core by 31.1% (4574 versus 3153) and R20 multi-core by 15.9% (15616 versus 13140). However, R23 multi-core goes to the 273PE: 31288 versus 30055, a 4.1% margin. This inconsistency suggests the two chips respond differently to varying workload durations and thermal conditions.

PassMark tests favor the i9-14900HX in most categories. Data compression shows a 539965 score against 405885, a 24.8% gap. Data encryption shows 32619 versus 22719, a 30.4% gap. Extended instructions show 31247 versus 24630, a 21.2% gap. Random string sorting shows 60861 versus 45098, a 25.9% gap. Integer math shows 157375 versus 139410, an 11.4% gap. Floating point math shows 112273 versus 107884, a 3.9% gap. Multi-threaded PassMark shows 43778 versus 36810, a 15.9% gap. Single-thread PassMark shows 4175 versus 3650, a 12.6% gap.

The 273PE wins the remaining PassMark tests. Prime number finding scores 203 versus 193, a 5.2% margin. Physics scores 3120 versus 2638, an 18.3% margin. The 273PE also records a Geekbench single-core score of 2330, but the i9-14900HX has no Geekbench multi-core or single-core comparison in the head-to-head set, so those appear only in the i9-14900HX's own benchmark list.

Where Each One Wins

The Intel Core 9 273PE is the stronger choice for single-threaded Cinebench workloads. Its R23 single-core advantage of 102.5% is massive, and its R15 single-core lead of 43.3% reinforces that pattern. The physics test also goes to the 273PE by 18.3%, and prime number finding by 5.2%. The 273PE's 5.70 GHz boost clock, while slightly lower than the i9-14900HX's 5.80 GHz, appears to deliver better single-thread performance in the recorded R15 and R23 tests. Its desktop socket and 65 W TDP suggest a design aimed at sustained single-thread response.

The Intel Core i9-14900HX is the stronger choice for parallel and data-heavy workloads. Its 24 cores and 32 threads give it a clear edge in multi-threaded PassMark, where it leads by 15.9%, and in data compression, where it leads by 24.8%. The encryption lead of 30.4% and extended instructions lead of 21.2% show the i9-14900HX handling computationally dense tasks with more headroom. Its mobile socket and 55 W TDP, combined with an unlocked multiplier, make it a flexible part for workloads that scale across many threads.

The R23 multi-core result is the notable exception. The 273PE wins that test by 4.1% despite having fewer cores. This suggests the 273PE's per-core efficiency, as demonstrated by its single-core R23 score, can overcome the i9-14900HX's core count in certain sustained multi-threaded scenarios. The R15 and R20 multi-core tests, however, both go to the i9-14900HX by 31.1% and 15.9% respectively, so the 273PE's R23 win does not generalize across all Cinebench versions.

The percentile data places both chips near each other in the global CPU ranking: 91st percentile for the i9-14900HX and 90th for the 273PE. The nearest rivals in the database confirm this positioning. The 273PE sits within 1.2% of the AMD Ryzen AI Max+ 388, Intel Core i5-14600KF, Intel Core i9-13980HX, and AMD Ryzen AI 9 HX PRO 370. The i9-14900HX sits within 1% of the Intel Core 7 253PQE, AMD Ryzen AI Max 390, AMD Ryzen AI 9 HX PRO 470, and AMD Ryzen Threadripper PRO 3955WX. The two Intel parts occupy adjacent performance tiers, with the i9-14900HX holding a higher average score and one additional percentile point.
