Intel Core 9 273PTE vs Intel Core Ultra 7 265 Comparison

Intel Core 9 273PTE vs Intel Core Ultra 7 265

Where Each One Wins

The benchmark data splits these two desktop processors into a clear division of labor. The Intel Core 9 273PTE wins exactly two of the seventeen recorded head-to-head tests, both in the Cinebench R20 suite. The Intel Core Ultra 7 265 wins the remaining fifteen tests, including all Passmark workloads and the other two Cinebench versions. The Core 9 273PTE takes the R20 multicore score with 8586 against 6268, a 37% advantage, and the R20 singlecore score with 1212 against 884, a 37.1% edge. Those wins suggest a specific strength in the R20 workload, but the broader pattern shows the Core Ultra 7 265 dominating across most compute types.

The Core Ultra 7 265 holds an 82-point percentile advantage, sitting at the 93rd percentile of all CPUs compared to the Core 9 273PTE's 82nd percentile. Its average benchmark score of 64640 is more than double the Core 9 273PTE's 31143. In the nearest rival comparison, the Core Ultra 7 265 sits within 0.7% of AMD EPYC 7343 and within 0.3% of the Core Ultra 7 265F, while the Core 9 273PTE sits within 0.5% of the Intel Core i7-12650HX and within 0.4% of the Intel Core i7-13700TE. The data indicates the Core Ultra 7 265 is a higher-tier part, while the Core 9 273PTE competes in a lower performance bracket.

Architecture Differences

The two chips come from different Intel design generations. The Core 9 273PTE uses the Bartlett Lake codename on a 10 nm process node fabricated by Intel, while the Core Ultra 7 265 uses the Arrow Lake-S codename on a 3 nm process node fabricated by TSMC. The Core 9 273PTE has 12 cores and 24 threads, whereas the Core Ultra 7 265 has 20 cores and 20 threads, meaning no hyperthreading on the latter. The Core Ultra 7 265 carries 17,800 million transistors on a 243 mm² die, while the Core 9 273PTE has no recorded transistor count or die size.

Cache configurations differ significantly. The Core 9 273PTE provides 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The Core Ultra 7 265 provides 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The Core 9 273PTE has more total L3, but the Core Ultra 7 265 has larger per-core L1 and L2 allocations. Memory support also splits: the Core 9 273PTE supports both DDR4 and DDR5 with a dual-channel bus at 89.6 GB/s, while the Core Ultra 7 265 supports only DDR5 with a dual-channel bus at 102.4 GB/s. The Core 9 273PTE supports ECC memory, the Core Ultra 7 265 does not.

Socket compatibility is a major divider. The Core 9 273PTE uses Intel Socket 1700 with 16 PCIe Gen 5 lanes from the CPU, while the Core Ultra 7 265 uses Intel Socket 1851 with 20 PCIe Gen 5 lanes from the CPU. Integrated graphics differ as well: the Core 9 273PTE uses UHD Graphics 730, the Core Ultra 7 265 uses Arc Xe-LPG Graphics 32EU. The Core 9 273PTE has a base clock of 1.40 GHz and a boost clock of 5.50 GHz, while the Core Ultra 7 265 has a base clock of 2.40 GHz and a boost clock of 5.30 GHz. The Core Ultra 7 265 has a higher base clock but a slightly lower boost clock. The Core Ultra 7 265 has a 65 TDP versus the Core 9 273PTE's 45 TDP. Both have locked multipliers and are active production parts.

Head-to-Head Benchmarks

The largest single victory for the Core Ultra 7 265 comes in Passmark find prime numbers, where it scores 418 against 142, a 66% advantage. Passmark floating point math shows a similar gap: 172776 versus 60673, a 64.9% delta. Data encryption favors the Core Ultra 7 265 at 40456 versus 14253, a 64.8% lead, and extended instructions follow at 41478 versus 15952, a 61.5% gap. Random string sorting goes to the Core Ultra 7 265 at 63833 versus 28973, a 54.6% margin. The Core Ultra 7 265 also wins data compression by a wide margin, 522983 versus 258704, a 50.5% difference.

The Cinebench results are inconsistent between versions. In R15 multicore, the Core Ultra 7 265 scores 4255 against 2060, a 51.6% lead. In R15 singlecore, it scores 600 against 290, a 51.7% lead. In R23 multicore, the Core Ultra 7 265 scores 42216 against 20445, another 51.6% lead, and in R23 singlecore it scores 5960 against 2886, also a 51.6% lead. But in R20, the results flip. The Core 9 273PTE wins multicore with 8586 versus 6268, a 37% margin, and singlecore with 1212 versus 884, a 37.1% margin. The R20 anomaly stands out against the otherwise consistent pattern of Core Ultra 7 265 dominance.

Passmark multithread shows the Core Ultra 7 265 ahead at 49682 versus 24054, a 51.6% lead. Passmark integer math favors the Core Ultra 7 265 at 134773 versus 82411, a 38.9% gap. Passmark physics goes to the Core Ultra 7 265 at 2923 versus 1917, a 34.4% margin. Passmark single thread and singlethread (both recorded as 4689) beat the Core 9 273PTE's 3433, a 26.8% lead. The closest overall margin outside the R20 wins is the single-thread Passmark test, where the Core Ultra 7 265 leads by less than a third. The data shows the Core 9 273PTE only outperforms in that specific R20 workload, and nowhere else.

The Verdict

The recorded data points to the Intel Core Ultra 7 265 as the stronger processor for almost every workload. It wins fifteen of seventeen head-to-head tests, holds a 93rd percentile ranking versus the 82nd percentile of the Core 9 273PTE, and delivers an average benchmark score more than double that of its rival. The largest margins come in compute-heavy Passmark tests: 66% ahead in prime number finding, 64.9% ahead in floating point math, and 64.8% ahead in data encryption. The Core Ultra 7 265 also leads by over 50% in Cinebench R15 and R23, both single and multicore, and in Passmark multithread and data compression.

The Intel Core 9 273PTE has one specific strength in Cinebench R20, where it leads by 37% multicore and 37.1% singlecore. That result is isolated and does not carry over to R15 or R23. The Core 9 273PTE also has the higher boost clock at 5.50 GHz versus 5.30 GHz, plus ECC support and DDR4 compatibility. Those features matter for specific use cases, but they do not translate into broader benchmark wins.

For a builder choosing between the two, the data favors the Core Ultra 7 265 for general multi-threaded performance, single-thread speed, and almost all compute tasks. The Core 9 273PTE is the choice only if the workload specifically relies on Cinebench R20 results, requires ECC memory, or needs DDR4 support. The Core Ultra 7 265 also has a lower launch MSRP of $394 against the Core 9 273PTE's $549, though pricing should not drive the decision. The benchmark record is clear: the Core Ultra 7 265 is the higher-performing chip, and the Core 9 273PTE holds a narrow niche advantage.
