Intel Core 9 273PQE vs Intel Core Ultra 7 265F Comparison

The Intel Core 9 273PQE and Intel Core Ultra 7 265F represent two distinct design philosophies within Intel’s desktop lineup, separated by process technology, core architecture, and platform. The benchmark data shows a decisive overall victory for the Core Ultra 7 265F, which wins 15 of 17 head-to-head tests, yet the Core 9 273PQE secures two significant wins in workloads that favor its specific configuration. This analysis compares the two processors across rendering, computational, and system-level workloads, drawing exclusively on the provided benchmark scores and specifications.

Head-to-Head Benchmarks

The most striking pattern in the data is the consistent, narrow lead held by the Core Ultra 7 265F across all Cinebench tests. In Cinebench R15, R20, and R23, the Ultra 7 265F outperforms the Core 9 273PQE by a nearly identical margin of 6.6% in both single-core and multi-core runs. For instance, in Cinebench R23 multi-core, the Ultra 7 265F scores 41,980 against 39,190 for the Core 9 273PQE, a delta of -6.6%. The single-core results mirror this: 5,926 versus 5,532 in R23 single-core, again a 6.6% advantage. This uniformity across rendering generations suggests a fundamental per-thread and multi-thread efficiency advantage for the Arrow Lake architecture, not a workload-specific quirk.

The Core 9 273PQE’s wins are concentrated in PassMark’s integer-heavy and compression tasks. In PassMark integer math, the Core 9 273PQE scores 164,629 versus 138,078 for the Ultra 7 265F, a 19.2% advantage. Similarly, in data compression, the Core 9 273PQE achieves 585,752 compared to 507,018, a 15.5% lead. These are substantial margins, indicating that the Core 9 273PQE’s design excels at processing highly parallel, non-floating-point workloads, likely benefiting from its 24 threads versus the Ultra 7 265F’s 20 threads.

Beyond rendering, the Ultra 7 265F dominates computational throughput in most other PassMark subtests. Its largest victory is in floating-point math, where it scores 173,855 against 125,546 for the Core 9 273PQE, a 27.8% advantage. The Ultra 7 265F also crushes the Core 9 273PQE in find prime numbers (416 versus 198, a 52.4% lead) and data encryption (39,468 versus 29,636, a 24.9% lead). In multithreaded performance, the Ultra 7 265F scores 49,410 versus 46,107, a 6.7% edge. The Core 9 273PQE only narrows the gap in extended instructions (38,743 versus 39,235, a 1.3% deficit) and single-thread performance (4,573 versus 4,750, a 3.7% deficit), but it never overtakes the Ultra 7 265F in those areas.

Architecture Differences

The two processors are built on fundamentally different platforms. The Intel Core 9 273PQE uses the Bartlett Lake architecture, fabricated on Intel’s 10 nm process, and fits the Intel Socket 1700. It features 12 cores and 24 threads, with a base clock of 3.40 GHz and a boost clock of 5.90 GHz. Its thermal design power (TDP) is 125 watts. In contrast, the Intel Core Ultra 7 265F belongs to the Arrow Lake-S family (Core Ultra Series 2), built on TSMC’s 3 nm process, and uses Intel Socket 1851. It has 20 cores and 20 threads, with a base clock of 2.40 GHz and a boost clock of 5.30 GHz, and a notably lower TDP of 65 watts.

Cache hierarchies differ significantly. The Core 9 273PQE provides 80 KB of L1 per core and 2 MB of L2 per core, with 36 MB of shared L3 cache. The Ultra 7 265F offers larger per-core caches: 192 KB of L1 and 3 MB of L2, but a smaller 30 MB of shared L3. Despite having fewer threads, the Ultra 7 265F’s higher per-core cache and newer process node likely contribute to its superior single-thread and floating-point performance, as evidenced by the benchmark data.

Memory support also diverges. The Core 9 273PQE supports both DDR4 and DDR5 memory on a dual-channel bus, with a memory bandwidth of 89.6 GB/s. The Ultra 7 265F supports only DDR5, also dual-channel, but with a higher bandwidth of 102.4 GB/s. The Core 9 273PQE includes ECC memory support and integrated UHD Graphics 770, while the Ultra 7 265F has no integrated graphics and no ECC support. PCIe connectivity favors the Ultra 7 265F, which offers Gen 5 with 20 CPU lanes versus 16 lanes on the Core 9 273PQE. The Ultra 7 265F also has a much larger transistor count (17,800 million) on a 243 mm² die, compared to unspecified figures for the Core 9 273PQE.

Where Each One Wins

The Core 9 273PQE is the clear choice for integer-heavy, parallel processing tasks. Its 19.2% lead in PassMark integer math and 15.5% lead in data compression indicate strong performance in workloads like database indexing, compression algorithms, and certain scientific computations that rely on integer arithmetic. The additional 4 threads (24 versus 20) provide a tangible advantage in these specific, non-floating-point scenarios. However, this advantage is narrow in scope, as the Core 9 273PQE loses every other benchmark.

The Ultra 7 265F is the superior processor for the vast majority of workloads. Its consistent 6.6% lead in Cinebench across all versions makes it the better choice for 3D rendering, video encoding, and other multi-threaded creative applications. The 27.8% advantage in floating-point math is particularly notable for scientific simulations, engineering analysis, and financial modeling that rely heavily on floating-point operations. The 52.4% lead in find prime numbers suggests strong performance in cryptography and number-theoretic computations. The 24.9% advantage in data encryption makes it preferable for security-related tasks. The Ultra 7 265F also wins in physics simulations (13.2% lead), random string sorting (14.8% lead), and general multithreaded workloads (6.7% lead), making it a more balanced and versatile processor.

The Verdict

The benchmark data is unambiguous: the Intel Core Ultra 7 265F is the superior processor for nearly every workload category, winning 15 of 17 head-to-head tests. Its consistent 6.6% lead across all Cinebench versions, combined with massive advantages in floating-point math (27.8%), encryption (24.9%), and prime number finding (52.4%), makes it the better choice for professionals in 3D rendering, scientific computing, cryptography, and general productivity. The lower TDP of 65 watts versus 125 watts further enhances its appeal for power-conscious builds, and the higher memory bandwidth of 102.4 GB/s supports memory-intensive applications.

The Intel Core 9 273PQE is not without merit. Its 19.2% lead in integer math and 15.5% lead in data compression make it the preferred option for specific workloads like database management, compression utilities, and integer-based simulations.
