Intel Core 9 273PE vs Intel Core i5-14400F Comparison

The Verdict

The Intel Core 9 273PE is the clear performance leader in this comparison. Benchmark data shows it wins 15 of 17 head-to-head tests, with the Intel Core i5-14400F taking only two narrow single-thread PassMark victories. The Core 9 273PE delivers consistently higher scores across Cinebench and PassMark workloads, with margins ranging from 23.5% to 136% in its wins.

The Core 9 273PE targets users who need maximum multi-threaded throughput. Its Cinebench R23 multi-core score of 31,288 versus 21,645 for the i5-14400F represents a 44.6% advantage. The Core 9 273PE also ranks in the 90th percentile among all CPUs in the database, while the i5-14400F sits at the 83rd percentile. The average benchmark score of 49,845 for the Core 9 273PE places it 54.5% above the i5-14400F's 32,279 average.

The i5-14400F remains a capable desktop processor with its own strengths. It posts a PassMark single-thread score of 3,701, slightly ahead of the Core 9 273PE's 3,650, a 1.4% margin. This makes the i5-14400F marginally better for lightly threaded tasks where a single core dominates. However, the Core 9 273PE counters with a Cinebench R23 single-core score of 4,417 versus 3,055, a 44.6% advantage, so the i5-14400F's single-thread win is isolated to the PassMark metric.

The Core 9 273PE is the choice for rendering, compilation, physics simulation, and any workload that scales across cores. The i5-14400F suits basic desktop use where its lower thread count and smaller cache do not hinder performance. The data does not support recommending the i5-14400F for demanding multi-threaded applications.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent 44.6% advantage for the Core 9 273PE across all six tests. In R15 multi-core, the Core 9 273PE scores 3,153 against 2,181. R20 multi-core shows 13,140 versus 9,090. R23 multi-core delivers 31,288 versus 21,645. Single-core results follow the same pattern: R15 single-core 445 versus 307, R20 single-core 1,855 versus 1,283, and R23 single-core 4,417 versus 3,055.

The PassMark suite reveals the largest margins. The Core 9 273PE leads in find prime numbers by 136%, scoring 203 versus 86. Physics shows a 104.9% advantage with 3,120 against 1,523. Floating point math delivers 107,884 versus 61,319, a 75.9% gain. Integer math follows with 139,410 versus 81,524, a 71% margin. Data encryption shows 22,719 versus 16,949, a 34% lead. Random string sorting gives 45,098 versus 32,680, a 38% margin. Data compression reaches 405,885 versus 315,521, a 28.6% advantage. Extended instructions score 24,630 versus 19,937, a 23.5% lead. The multithread test shows 36,810 versus 25,470, a 44.5% margin.

The i5-14400F wins only the two PassMark single-thread tests. Its score of 3,701 edges the Core 9 273PE's 3,650 by 1.4%. This is the sole area where the i5-14400F demonstrates superiority, and the margin is small.

Where Each One Wins

The Core 9 273PE dominates in every multi-threaded workload recorded. Cinebench multi-core tests show a 44.6% advantage, which directly benefits rendering, video encoding, and 3D modeling. The PassMark multithread test confirms this with a 44.5% lead, indicating strong scaling across its 24 threads. The physics score of 3,120 versus 1,523 represents a 104.9% gain, making the Core 9 273PE the clear pick for simulation and physics-based workloads.

The Core 9 273PE also wins in memory-intensive and data-heavy tasks. Data compression scores 405,885 versus 315,521, a 28.6% advantage, aided by the larger 36 MB L3 cache. Random string sorting shows a 38% lead. Integer and floating point math deliver 71% and 75.9% gains respectively, which translates to scientific computing and financial modeling. Find prime numbers shows the biggest relative gap at 136%, indicating strong raw integer throughput.

The i5-14400F wins only in the PassMark single-thread metric, scoring 3,701 versus 3,650. This 1.4% margin applies to legacy or single-threaded applications that rely on PassMark's specific workload. However, Cinebench R23 single-core shows the Core 9 273PE ahead by 44.6% with 4,417 versus 3,055. The i5-14400F's single-thread win is therefore metric-specific and does not extend to Cinebench's single-core test.

For users selecting based on recorded data, the Core 9 273PE is the superior processor for 15 of 17 benchmarks, with its nearest rivals in the database being the AMD Ryzen AI Max+ 388 (0.1% ahead in average score), Intel Core i9-13980HX (1.1% behind), and AMD Ryzen AI 9 HX PRO 370 (1.2% behind). The i5-14400F's nearest rivals include the AMD Ryzen 7 PRO 8840U (0.1% ahead), Intel Core i9-11900 (0.2% ahead), and AMD Ryzen 7 6800HS (0.2% behind). The Core 9 273PE sits in a higher performance tier, while the i5-14400F competes in a lower tier. The data supports the Core 9 273PE for any workload where multi-threading matters, and the i5-14400F only for narrowly defined single-thread PassMark scenarios.
