Architecture Differences

The two processors represent fundamentally different Intel designs. The Intel Core 9 273PE belongs to the Bartlett Lake generation and carries the codename Bartlett Lake. It fits the Intel Socket 1700 platform. The Intel Core Ultra 7 265K belongs to the Core Ultra Series 2, uses the Arrow Lake architecture, and carries the Arrow Lake-S codename. It fits the Intel Socket 1851 platform.

Manufacturing processes differ sharply. The Core 9 273PE is fabricated on Intel's 10 nm node. The Core Ultra 7 265K is fabricated on TSMC's 3 nm node. The Core Ultra 7 265K reports 17,800 million transistors and a die size of 243 mm², while the Core 9 273PE does not list transistor or die size data.

Core organization also differs. The Core 9 273PE has 12 cores and 24 threads, indicating hyperthreading support. The Core Ultra 7 265K has 20 cores and 20 threads, indicating no hyperthreading. Cache hierarchies follow different patterns: the Core 9 273PE has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The Core Ultra 7 265K has 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3.

Memory support diverges as well. The Core 9 273PE supports both DDR4 and DDR5 memory, while the Core Ultra 7 265K supports DDR5 only. Both use dual-channel memory buses, but the Core Ultra 7 265K achieves a higher memory bandwidth of 102.4 GB/s versus 89.6 GB/s for the Core 9 273PE. Both support ECC memory.

PCIe connectivity favors the Core Ultra 7 265K, which provides Gen 5 with 20 lanes (CPU only). The Core 9 273PE provides Gen 5 with 16 lanes (CPU only). Integrated graphics also differ: the Core 9 273PE uses UHD Graphics 730, while the Core Ultra 7 265K uses Arc Xe-LPG Graphics 64EU.

The multiplier situation is another distinction. The Core Ultra 7 265K has an unlocked multiplier, while the Core 9 273PE does not. This means the Core Ultra 7 265K supports user overclocking, while the Core 9 273PE is locked.

Where Each One Wins

The head-to-head benchmark data divides the two processors into distinct usage profiles. The Intel Core Ultra 7 265K dominates nearly every measured workload, winning 16 of 17 comparisons. Its wins span Cinebench R15, R20, and R23 multi-core tests, all PassMark workloads, and the PassMark single-thread tests. The Core Ultra 7 265K also holds the only Geekbench results in the database, with scores of 23085 multi-core and 2713 single-core, while the Core 9 273PE has no Geekbench entries.

The Core 9 273PE wins exactly one recorded benchmark: Cinebench R23 single-core. Its score of 4417 versus 2020 for the Core Ultra 7 265K represents a massive 118.7 percent advantage in that test. This result stands out because the Core 9 273PE loses the Cinebench R15 single-core test (445 versus 708) and the Cinebench R20 single-core test (1855 versus 2953). The R23 single-core result is an outlier relative to the other Cinebench single-core tests, but it is the recorded data.

In practical terms, the Core Ultra 7 265K is the stronger processor for multi-threaded rendering, data compression, encryption, floating-point math, integer math, physics simulation, and random string sorting. Its lead over the Core 9 273PE in these workloads ranges from 2.7 percent in PassMark integer math to 58.7 percent in PassMark find prime numbers.

The Core 9 273PE's single win suggests it has a narrow advantage in one specific single-threaded rendering scenario, but the broader single-thread data favors the Core Ultra 7 265K. The Core Ultra 7 265K also leads in PassMark single-thread (4928 versus 3650) and PassMark singlethread (4928 versus 3650), both by 25.9 percent.

PassMark integer math is the closest contest: the Core Ultra 7 265K scores 143242 versus 139410 for the Core 9 273PE, a delta of only -2.7 percent.

The single win for the Core 9 273PE is Cinebench R23 single-core. The Core 9 273PE scores 4417, the Core Ultra 7 265K scores 2020, and the delta is +118.7 percent in favor of the Core 9 273PE. This result is anomalous within the Cinebench single-core series, as the Core Ultra 7 265K wins both R15 and R20 single-core by margins around 37 percent. The R23 single-core result may reflect different test conditions or workload characteristics, but the database records it as the only benchmark victory for the Core 9 273PE.

The average benchmark scores reinforce the Core Ultra 7 265K's overall position. Its 70879 average places it near the Intel Xeon 6511P at 71051 (-0.2 percent) and the Intel Xeon Platinum 8270 at 71370 (-0.7 percent), while running ahead of the Intel Core i7-14700KF at 70163 (1 percent) and the AMD Ryzen 7 9700F at 69996 (1.3 percent). The Core 9 273PE's 49845 average sits close to the AMD Ryzen AI Max+ 388 at 49796 (0.1 percent) and the Intel Core i5-14600KF at 49394 (0.9 percent), while trailing the Intel Core i9-13980HX at 50398 (-1.1 percent) and the AMD Ryzen AI 9 HX PRO 370 at 50448 (-1.2 percent). These rival comparisons place the Core Ultra 7 265K in a higher performance tier overall, despite the Core 9 273PE's single R23 single-core triumph.
