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

Head-to-Head Benchmarks

The benchmark data presents an unambiguous picture: the Intel Core i9-14900KS wins all 17 recorded head-to-head tests. The Core 9 273PTE does not secure a single victory. The margins, however, vary significantly across workloads, revealing where the gap is narrow and where it becomes a chasm.

In Cinebench tests, the i9-14900KS demonstrates overwhelming dominance. In the R15 multicore test, the i9 scores 5140 against the Core 9's 2060, a delta of -59.9% for the latter. The R15 singlecore test shows a similar pattern: 725 versus 290, a -60% delta. This trend persists through R20 and R23. The R20 multicore result is 21417 against 8586 (-59.9%), while R20 singlecore is 3023 versus 1212 (-59.9%). The R23 multicore score of 50995 dwarfs the Core 9's 20445 (-59.9%), and R23 singlecore of 7199 versus 2886 yields the same -59.9% delta. The consistency of this ~60% deficit across all Cinebench versions indicates a fundamental throughput advantage for the i9, not a workload-specific quirk.

PassMark results add nuance. The smallest margin appears in single-thread performance. The i9-14900KS posts 4815 in PassMark single-thread, while the Core 9 manages 3433, a -28.7% delta. This is the closest the Core 9 comes to matching its rival, and it still represents a substantial gap. The largest deficit for the Core 9 appears in data encryption: 14253 versus 47717, a -70.1% delta. Data compression follows closely at -67.8% (258704 versus 803368), and random string sorting shows -67.7% (28973 versus 89789). Extended instructions also favor the i9 heavily: 45524 versus 15952, a -65% delta.

Other PassMark tests show the i9 ahead by roughly 60%. Floating point math: 153975 versus 60673 (-60.6%). Integer math: 212644 versus 82411 (-61.2%). Multithread: 60012 versus 24054 (-59.9%). The two most moderate deltas outside single-thread are find prime numbers at -41.8% (244 versus 142) and physics at -43.3% (3381 versus 1917). These latter two tests involve less parallelizable or more latency-sensitive workloads, yet the i9 still wins decisively.

The average benchmark score reinforces the hierarchy. The i9-14900KS holds an avgBenchmarkScore of 81127, while the Core 9 273PTE sits at 31143. The percentile rankings tell the broader story: the i9 ranks in the 96th percentile of all CPUs, whereas the Core 9 ranks in the 82nd. This places the Core 9 in a mid-to-high tier, but the i9 operates near the top of the entire database.

Architecture Differences

The two processors share the same socket, Intel Socket 1700, and both use a 10 nm process node from Intel. They also share identical cache hierarchies: 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. Memory support is identical as well, with both supporting DDR4 and DDR5 in dual-channel mode, and both support ECC memory. PCIe connectivity matches: Gen 5 with 16 lanes from the CPU.

The differences begin with the fundamental design. The Core 9 273PTE uses the Bartlett Lake codename and belongs to the "Core 9 (Bartlett Lake)" generation. The i9-14900KS uses Raptor Lake architecture, specifically the Raptor Lake-R codename, and belongs to the "Core i9 (Raptor Lake Refresh)" generation. This architectural separation explains much of the performance gap.

Core and thread counts diverge sharply. The Core 9 provides 12 cores and 24 threads. The i9-14900KS provides 24 cores and 32 threads. This doubling of physical cores, combined with a different core topology, drives the multicore benchmark advantages. The i9 also has a higher base clock of 3.20 GHz versus 1.40 GHz, and a higher boost clock of 6.20 GHz versus 5.50 GHz. These clock differences are significant, particularly the 6.20 GHz boost, which is exceptional.

Thermal design power differs considerably: the Core 9 is rated at 45 W, while the i9-14900KS is rated at 150 W. This nearly 3.3x difference in TDP reflects the i9's higher clocks and larger core count. The die size is recorded only for the i9 at 257 mm²; the Core 9's die size is not listed.

The integrated graphics differ: the Core 9 uses UHD Graphics 730, while the i9 uses UHD Graphics 770. The memory bandwidth figure is recorded only for the Core 9 at 89.6 GB/s; the i9's value is not listed. The i9-14900KS has an unlocked multiplier, while the Core 9's multiplier is locked. The release dates differ by about two years: the Core 9 launched in March 2026, while the i9 launched in March 2024. The i9's launch MSRP was $689, and the Core 9's launch MSRP was $549.

Where Each One Wins

The Intel Core i9-14900KS wins every recorded benchmark. In Cinebench multicore tests, its advantage is approximately 60% across R15, R20, and R23. In PassMark integer math, floating point math, and multithread tests, the i9 leads by roughly 60% as well. The i9's strongest areas are data encryption (-70.1% delta), data compression (-67.8%), and random string sorting (-67.7%), suggesting particular strength in memory-intensive and cryptographic workloads.

The Intel Core 9 273PTE has no benchmark wins in the recorded data. Its closest relative performance appears in single-thread tests, where the i9 leads by only -28.7%. In find prime numbers and physics tests, the i9's lead narrows to -41.8% and -43.3%, respectively. These figures suggest the Core 9 is comparatively less disadvantaged in latency-sensitive or less parallelizable tasks, though it still loses by substantial margins.

The average benchmark scores place the i9 in the 96th percentile of all CPUs, while the Core 9 sits in the 82nd percentile. The i9's nearest rivals, the Intel Xeon w5-3535X and AMD Ryzen 9 8940HX, have average scores within 0% delta, indicating the i9 is competitive with top-tier workstation and mobile chips. The Core 9's nearest rivals, including the Intel Core i7-12700F and AMD Ryzen 9 8945HS, are within 0.2% to 0.5% delta, placing it in a mainstream performance tier.

The Verdict

The data indicates a clear choice for users prioritizing maximum performance: the Intel Core i9-14900KS. Its 24 cores, 32 threads, 6.20 GHz boost clock, and 150 W TDP deliver benchmark results that are roughly 60% higher in most multicore tests and nearly 30% higher in single-thread tests compared to the Core 9 273PTE. The i9's 96th percentile ranking versus the Core 9's 82nd percentile confirms this hierarchy across the entire CPU database.

The Intel Core 9 273PTE, with its 12 cores, 24 threads, 5.50 GHz boost clock, and 45 W TDP, offers a different trade-off. Its launch MSRP was $549 versus the i9's $689, and its lower TDP suggests a more modest power envelope. However, the benchmark data shows no workload where the Core 9 outperforms the i9. The Core 9's closest margin is in single-thread performance, but even there it trails by 28.7%.

For scenarios requiring maximum multi-threaded throughput, such as rendering, encryption, or data compression, the i9-14900KS is the stronger option based on the recorded scores. For users constrained by power limits or seeking a lower launch MSRP, the Core 9 273PTE presents a viable alternative, though it sacrifices significant performance in every measured category. The i9-14900KS, released in March 2024, remains the higher-performing part in this comparison, with the Core 9 273PTE, released in March 2026, positioned clearly below it in the benchmark hierarchy.
