Data compression reaches 405,885, and data encryption records 22,719. Extended instructions score 24,630, floating point math reaches 107,884, and integer math hits 139,410. The processor also records 45,098 in random string sorting, 3,120 in physics, and 203 in find prime numbers.

The nearest rivals for the Core 9 273PE provide context for its standing. The AMD Ryzen AI Max+ 388 has an average benchmark score of 49,796, which is 0.1 percent higher than the Core 9 273PE's average of 49,845. The Intel Core i5-14600KF scores 49,394, placing it 0.9 percent behind. The Intel Core i9-13980HX reaches 50,398, putting it 1.1 percent ahead. The AMD Ryzen AI 9 HX PRO 370 records 50,448, which is 1.2 percent ahead.

Since the Core Ultra 7 155UL has no benchmark entries, its average benchmark score is recorded as zero, and it has no nearest rivals listed. The database shows no wins for either processor in head-to-head testing because no comparative test results exist for the Core Ultra 7 155UL.

Where Each One Wins

The Core 9 273PE is the only processor in this comparison with measurable benchmark outcomes. Its Cinebench R23 multi-core result of 31,288 indicates strong parallel processing capability, which supports heavy multi-threaded workloads such as rendering, encoding, and scientific computation. The single-core R23 score of 4,417 shows solid per-thread performance, beneficial for applications that rely on single-thread responsiveness.

PassMark data reveals specific strengths for the Core 9 273PE. The integer math score of 139,410 and floating point math score of 107,884 suggest robust arithmetic processing. Data compression at 405,885 points to efficient handling of compressed data streams. Extended instructions at 24,630 indicate the processor can accelerate specialized instruction sets.

The Core Ultra 7 155UL has no recorded wins because no benchmark data exists in the database. Its performance profile cannot be assessed through measured results. The processor does carry a 15 watt TDP, which indicates a low-power design, but without scores, its competitive positioning remains undefined in the recorded data.

The Core 9 273PE's 90th percentile ranking among all CPUs confirms that its measured performance exceeds the vast majority of processors in the database. Its nearest rivals, all within 1.2 percent of its average score, show that it competes directly with high-end mobile and desktop parts from both Intel and AMD.

Architecture Differences

The two processors share several architectural traits but diverge in key areas. Both have 12 cores, though the Core 9 273PE supports 24 threads while the Core Ultra 7 155UL supports 14 threads. This difference indicates a distinct core organization between the two designs.

The Core 9 273PE uses the Bartlett Lake codename under the Core 9 generation, built on Intel's 10 nm process node. The Core Ultra 7 155UL belongs to the Core Ultra Series 1, using the Meteor Lake architecture with the Meteor Lake-PS codename, fabricated on a 7 nm node. Both come from Intel's foundry.

Cache hierarchies differ notably. The Core 9 273PE has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Core Ultra 7 155UL provides 112 KB of L1 cache per core, 2 MB of L2 cache per core, and 12 MB of shared L3 cache. The Core 9 273PE offers three times the L3 capacity, which can improve performance in workloads with large working sets.

Clock speeds show a significant gap. The Core 9 273PE has a base clock of 2.30 GHz and a boost clock of 5.70 GHz. The Core Ultra 7 155UL operates at 1.70 GHz base and 4.80 GHz boost. The Core 9 273PE's higher clocks, especially the 0.9 GHz boost advantage, contribute to its measured performance lead.

Power envelopes differ substantially. The Core 9 273PE has a 65 watt TDP, while the Core Ultra 7 155UL has a 15 watt TDP. This places the Core Ultra 7 155UL in a low-power category, suitable for systems prioritizing energy efficiency over peak performance.

Memory support shows both similarities and differences. Both processors use dual-channel memory with 89.6 GB/s bandwidth. The Core 9 273PE supports DDR4 and DDR5 memory, while the Core Ultra 7 155UL supports DDR5 with compatibility depending on the motherboard. The Core 9 273PE includes ECC memory support, while the Core Ultra 7 155UL does not.

PCIe capabilities differ. The Core 9 273PE provides Gen 5 with 16 lanes from the CPU, while the Core Ultra 7 155UL offers Gen 4 with 8 lanes. This gives the Core 9 273PE double the lane count and a newer generation for expansion devices.

Integrated graphics also diverge. The Core 9 273PE uses UHD Graphics 730, while the Core Ultra 7 155UL features Arc Xe-LPG 64EU. The Arc branding suggests a more modern graphics architecture, though no benchmark data quantifies their relative graphics performance.

Socket compatibility separates the two. The Core 9 273PE fits Intel Socket 1700, while the Core Ultra 7 155UL uses Intel Socket 1851. These are not interchangeable platforms.

Release dates differ by nearly two years. The Core Ultra 7 155UL launched on 2024-04-07, while the Core 9 273PE launched on 2026-03-08. Both remain in active production.

The Verdict

The data presents an unambiguous picture. The Intel Core 9 273PE is the only processor with recorded benchmark results, and those results place it at the 90th percentile of all CPUs. Its average benchmark score of 49,845 positions it alongside top-tier processors like the AMD Ryzen AI Max+ 388 at 49,796 and the Intel Core i9-13980HX at 50,398.

The Core Ultra 7 155UL has no benchmark scores in the database, leaving its performance unmeasured. Its 15 watt TDP and lower clock speeds of 1.70 GHz base and 4.80 GHz boost suggest a focus on efficiency rather than raw throughput. The 12 MB L3 cache and 14 threads indicate a more modest multi-threading capability compared to the Core 9 273PE's 24 threads and 36 MB L3 cache.

For workloads demanding high multi-core performance, the Core 9 273PE's Cinebench R23 score of 31,288 and PassMark multi-thread score of 36,810 make it the clear choice. Its 5.70 GHz boost clock also supports single-thread responsiveness, shown by the R23 single-core score of 4,417.

For systems where power consumption is the primary constraint, the Core Ultra 7 155UL's 15 watt TDP offers an efficiency profile that the 65 watt Core 9 273PE cannot match. However, without benchmark data, the performance trade-off cannot be quantified.

The recorded information supports selecting the Core 9 273PE for performance-oriented desktop builds, while the Core Ultra 7 155UL remains an option for low-power designs where measured performance is not yet established in the database.
