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

The Verdict

The recorded data is unambiguous. The Intel Core i9-14900KS wins every single head-to-head benchmark in the database, 17 out of 17. The Core 9 273PE does not win a single test. The i9-14900KS holds a 96th percentile ranking versus all CPUs, while the Core 9 273PE sits at the 90th percentile. The average benchmark score for the i9-14900KS is 81127, against 49845 for the Core 9 273PE.

The Core 9 273PE is positioned closer to different rivals. Its nearest competitors include the AMD Ryzen AI Max+ 388 with an average score of 49796 (a 0.1% difference) and the Intel Core i5-14600KF at 49394 (0.9% difference). The i9-14900KS sits near the Intel Xeon w5-3535X at 81115 (0% difference) and the AMD Ryzen 9 8940HX at 81103 (0% difference). The data suggests the Core 9 273PE competes in a lower performance tier entirely, despite sharing the same socket and process node.

For users prioritizing raw multi-threaded throughput, the i9-14900KS is the clear choice from these measurements. For users constrained by power limits or those who need ECC memory support with a lower power envelope, the Core 9 273PE offers a functional alternative, but the benchmark record shows it trails substantially in every measured workload.

Where Each One Wins

The i9-14900KS dominates across all benchmark categories in the database. The largest deltas come in memory-related and encryption workloads. Passmark data encryption shows a 52.4% advantage for the i9-14900KS. Random string sorting follows at 49.8%, and data compression at 49.5%. Extended instructions show a 45.9% gap. These are workloads where the i9-14900KS's higher core count and thread count translate directly into throughput.

The smallest delta between the two is in passmark physics, where the i9-14900KS leads by only 7.7%. This workload appears less sensitive to the architectural differences between the two chips. The find prime numbers test shows a 16.8% gap, also relatively modest compared to the larger deltas elsewhere.

The Core 9 273PE has no benchmark wins in the head-to-head table. Its closest relative performance comes in the physics test, where the 3120 score versus 3381 shows a narrower margin. The data indicates that single-thread performance differences are consistent but not overwhelming: cinebench R23 single-core shows a 38.6% gap, while passmark single-thread shows a 24.2% gap. The Core 9 273PE does not offer any measured advantage in any workload category.
