Intel Core 9 273PE vs Intel Core i5-14401E Comparison

Head-to-Head Benchmarks

The benchmark data paints a decisive picture: the Intel Core 9 273PE wins all six recorded head-to-head comparisons against the Intel Core i5-14401E, with no tests going the other way. The margin is remarkably consistent across both multi-core and single-core workloads, hovering around 72% in every case.

In Cinebench R15 multi-core, the Core 9 273PE scores 3153 against the i5-14401E's 1830, a 72.3% advantage. The single-core R15 test tells the same story: 445 versus 258, a 72.5% lead. Moving to Cinebench R20, the multi-core result is 13140 versus 7627 (72.3% ahead), while single-core shows 1855 versus 1076 (72.4% ahead). Cinebench R23 repeats the pattern: multi-core 31288 versus 18161 (72.3% ahead), single-core 4417 versus 2564 (72.3% ahead).

This consistency of roughly 72% across all six tests suggests the performance gap is structural rather than workload-specific. The Core 9 273PE does not merely edge ahead in certain tasks; it maintains the same proportional advantage whether the workload stresses one core or all of them. That uniformity indicates the difference comes from core count, thread count, and clock speeds working together, not from any single architectural feature.

The broader database context reinforces this gap. The Core 9 273PE sits at the 90th percentile of all CPUs, with an average benchmark score of 49845. Its nearest rivals include the AMD Ryzen AI Max+ 388 (49796, 0.1% behind), Intel Core i5-14600KF (49394, 0.9% behind), Intel Core i9-13980HX (50398, 1.1% ahead), and AMD Ryzen AI 9 HX PRO 370 (50448, 1.2% ahead). These are all close competitors, meaning the Core 9 273PE trades blows with high-end desktop and mobile parts.

The i5-14401E, by contrast, sits at the 60th percentile with an average benchmark score of 5253. Its nearest rivals are much older or lower-tier parts: Intel Xeon E5-2699A v4 (5259, 0.1% behind), Intel Core i7-11700B (5241, 0.2% ahead), Intel Core i9-10850K (5240, 0.2% ahead), and Intel Core i5-13400T (5210, 0.8% ahead). This places the i5-14401E in a completely different performance tier, one that the Core 9 273PE outclasses by a wide margin in every measured test.

Architecture Differences

The two CPUs share a common foundation but diverge in key architectural details. Both are built on Intel's 10 nm process and use Intel Socket 1700, so the physical platform and manufacturing technology are identical. The Core 9 273PE carries the codename Bartlett Lake, while the i5-14401E uses Raptor Lake-R. This codename difference reflects a generation gap: the Core 9 273PE is part of the Core 9 (Bartlett Lake) generation, and the i5-14401E belongs to the Core 14th Gen (Raptor Lake Refresh) series.

The cache hierarchy is where the architectures visibly separate. The Core 9 273PE has 2 MB of L2 cache per core, while the i5-14401E has 1.25 MB per core. That per-core difference compounds with core count: the Core 9 273PE has 12 cores, the i5-14401E has 6. The L3 cache tells a similar story, with the Core 9 273PE offering 36 MB shared versus 20 MB shared on the i5-14401E. Both use 80 KB of L1 cache per core. The larger L2 per core on the Core 9 273PE suggests a different cache design philosophy, one that gives each core more local storage for frequently accessed data.

The die size differs as well, though the database only records a figure for the i5-14401E: 215 mm². No die size is listed for the Core 9 273PE, so a direct comparison of physical chip dimensions is not possible from the recorded data. The Core 9 273PE also lacks a recorded architecture field, while the i5-14401E is explicitly listed as Raptor Lake architecture.

Both CPUs support ECC memory, a feature that matters for workstation and server-adjacent use cases. They also share the same PCIe configuration: Gen 5 with 16 lanes from the CPU. The integrated graphics are identical (UHD Graphics 730), which means any graphical difference between the two comes from the CPU cores themselves, not the iGPU.

Memory bandwidth is another point of divergence. The Core 9 273PE records 89.6 GB/s, while the i5-14401E has no bandwidth figure in the database. Both support DDR4 and DDR5, so the bandwidth advantage likely stems from the Core 9 273PE's higher core count and possibly different memory controller configuration, though the database does not specify a cause.

Specification Differences

The specification table shows clear deltas between the two parts across nearly every field. Core count differs most fundamentally: 12 cores on the Core 9 273PE versus 6 on the i5-14401E. Threads follow: 24 versus 12. Base clocks are close, with the Core 9 273PE at 2.30 GHz and the i5-14401E at 2.50 GHz, meaning the i5-14401E actually starts from a slightly higher base frequency. Boost clocks tell the opposite story: the Core 9 273PE reaches 5.70 GHz, while the i5-14401E tops out at 4.70 GHz. That 1.0 GHz boost advantage on the Core 9 273PE is substantial.

Both CPUs have a 65 W TDP, so power draw at the thermal envelope is identical. The socket is the same (Intel Socket 1700), as is the process node (10 nm) and foundry (Intel). L2 cache per core differs: 2 MB on the Core 9 273PE, 1.25 MB on the i5-14401E. L3 cache is 36 MB shared versus 20 MB shared. Memory support is identical (DDR4, DDR5, dual-channel), as is PCIe (Gen 5, 16 lanes). Both have ECC memory support and UHD Graphics 730.

The release dates are far apart: the Core 9 273PE launched on 2026-03-08, while the i5-14401E launched on 2024-06-30. The Core 9 273PE has a recorded launch MSRP of $549, while the i5-14401E has no launch MSRP in the database. Neither CPU has an unlocked multiplier, so overclocking is not a differentiator. The part numbers also differ: SA4QD for the Core 9 273PE, Q49JSRNJS for the i5-14401E. The i5-14401E has a listed die size of 215 mm², while the Core 9 273PE does not have one recorded.

Where Each One Wins

Based on the recorded benchmark data, the Core 9 273PE wins every single test. There is no workload category in the head-to-head results where the i5-14401E comes out ahead. The six Cinebench tests, spanning R15, R20, and R23 in both multi-core and single-core modes, all show the Core 9 273PE with roughly a 72% lead.

The Core 9 273PE is the clear choice for multi-threaded rendering, video encoding, simulation, and any workload that scales with core count. Its 12 cores and 24 threads give it double the parallel processing capacity of the i5-14401E. The 72.3% multi-core advantage across all three Cinebench versions confirms this is not a marginal gain but a decisive one. The 36 MB L3 cache also helps in workloads with large working sets that benefit from shared cache.

Single-core performance is equally one-sided. The Core 9 273PE's 5.70 GHz boost clock versus 4.70 GHz on the i5-14401E translates to a 72.3% to 72.5% advantage in single-threaded tests. This means even lightly threaded applications, such as older games or single-threaded productivity tools, run noticeably faster on the Core 9 273PE.

The i5-14401E does hold a few specification advantages, though they do not translate into benchmark wins. It has a higher base clock (2.50 GHz versus 2.30 GHz), which could matter for brief burst workloads before boost kicks in. It also has a smaller die size (215 mm²), which may imply lower manufacturing cost per chip, but the database provides no cost data. In practice, the i5-14401E's role is as a lower-tier option within the same socket and platform, suitable for builds where the 65 W TDP and Socket 1700 compatibility are the primary constraints and the performance gap is acceptable.

The Verdict

The data directs a straightforward choice: the Intel Core 9 273PE outperforms the Intel Core i5-14401E in every recorded benchmark, with a consistent 72% advantage across all six Cinebench tests. The Core 9 273PE doubles the core count (12 versus 6), doubles the thread count (24 versus 12), boosts 1.0 GHz higher (5.70 GHz versus 4.70 GHz), and offers more L2 per core (2 MB versus 1.25 MB) and more L3 total (36 MB versus 20 MB). These specification differences align with the benchmark results, confirming that the performance gap is real and consistent.

The Core 9 273PE sits at the 90th percentile of all CPUs, with an average benchmark score of 49845 and nearest rivals like the AMD Ryzen AI Max+ 388 and Intel Core i9-13980HX within a few percent. It is a high-end desktop part that competes with top-tier CPUs from both Intel and AMD. The i5-14401E, at the 60th percentile with an average score of 5253, competes with older parts like the Intel Core i9-10850K and Intel Core i7-11700B. These are entirely different performance tiers.

For a builder choosing between these two on the same Socket 1700 platform, the Core 9 273PE is the superior processor by every measurable metric in the database. It wins multi-core and single-core workloads alike, offers more cache, and reaches higher boost clocks. The i5-14401E is the lower-cost option (the database records no launch MSRP for it, while the Core 9 273PE has a $549 launch MSRP), but the performance gap is so large that the Core 9 273PE justifies its position for anyone prioritizing CPU throughput. The 65 W TDP is identical on both, so there is no thermal reason to prefer the i5-14401E. The verdict is unambiguous: the Core 9 273PE is the pick for performance, and the i5-14401E serves only as a budget-tier alternative within the same socket.
