Intel Core 9 273PTE vs Intel Core Ultra 7 155UL Comparison

# Intel Core 9 273PTE vs Intel Core Ultra 7 155UL

Head-to-Head Benchmarks

The Intel Core 9 273PTE and Intel Core Ultra 7 155UL present a stark contrast in benchmark coverage. The database contains an extensive set of measured scores for the Core 9 273PTE, while the Ultra 7 155UL has no recorded benchmark results. This absence of data for the Ultra 7 155UL means a direct numerical comparison of performance is not possible from the recorded measurements.

The Core 9 273PTE delivers a Cinebench R23 multi-core score of 20445 and a single-core score of 2886. In Cinebench R20, the chip records 8586 points multi-core and 1212 points single-core. The older Cinebench R15 test shows 2060 points multi-core and 290 points single-core. PassMark results for the Core 9 273PTE include a multi-thread score of 24054, single-thread score of 3433, integer math at 82411, floating point math at 60673, and extended instructions at 15952. Data compression reaches 258704, while data encryption scores 14253. Random string sorting produces 28973, find prime numbers yields 142, and physics scores 1917.

The Core 9 273PTE achieves an average benchmark score of 31143, placing it in the 82nd percentile among all CPUs in the database. Its nearest rivals show tight clustering: the Intel Core i7-12700F averages 31081 with a delta of +0.2%, the AMD Ryzen 9 8945HS averages 31074 with a delta of +0.2%, the Intel Core i7-13700TE averages 31028 with a delta of +0.4%, and the Intel Core i7-12650HX averages 31290 with a delta of -0.5%. These deltas indicate the Core 9 273PTE sits within half a percent of these comparable processors, effectively matching their overall performance levels.

The Ultra 7 155UL carries a 50th percentile ranking among all CPUs, but with no average benchmark score recorded, the percentile figure stands without supporting data. The database shows zero wins for either processor in head-to-head comparisons, reflecting the lack of paired benchmark results.

Architecture Differences

The two processors come from different architectural lineages. The Core 9 273PTE uses the Bartlett Lake codename, built on a 10 nm process node at Intel's foundry. It belongs to the Core 9 generation. The Ultra 7 155UL uses the Meteor Lake architecture with the Meteor Lake-PS codename, built on a 7 nm process node, also at Intel. It belongs to the Core Ultra Series 1 generation.

Core counts are identical at 12 cores, but thread counts differ substantially. The Core 9 273PTE supports 24 threads, implying hyper-threading across all cores. The Ultra 7 155UL supports only 14 threads, indicating a hybrid configuration where not all cores contribute two threads. This thread disparity directly impacts multi-threaded workload capability.

Clock speeds favor the Core 9 273PTE. Its base clock is 1.40 GHz with a boost clock of 5.50 GHz. The Ultra 7 155UL starts at a higher 1.70 GHz base but boosts to only 4.80 GHz. The 0.70 GHz boost advantage for the Core 9 273PTE is significant for single-threaded and lightly threaded performance.

Cache hierarchies differ in size and organization. The Core 9 273PTE provides 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Ultra 7 155UL offers 112 KB of L1 cache per core, 2 MB of L2 cache per core, and only 12 MB of shared L3 cache. The Core 9 273PTE holds a threefold advantage in L3 capacity, which benefits workloads with large working sets.

Memory support diverges as well. The Core 9 273PTE supports both DDR4 and DDR5 memory, while the Ultra 7 155UL supports DDR5 only, with capacity depending on the motherboard. Both use dual-channel memory buses with identical 89.6 GB/s bandwidth. ECC memory support exists on the Core 9 273PTE but is absent on the Ultra 7 155UL.

PCIe connectivity differs by generation and lane count. The Core 9 273PTE provides PCIe Gen 5 with 16 lanes from the CPU. The Ultra 7 155UL provides PCIe Gen 4 with 8 lanes from the CPU. The Core 9 273PTE offers twice the lane count and a newer generation, enabling higher bandwidth for expansion devices.

Integrated graphics also differ. The Core 9 273PTE uses UHD Graphics 730, while the Ultra 7 155UL uses Arc Xe-LPG 64EU. The Arc solution represents a more capable integrated GPU architecture, though no benchmark data exists for either in the database.

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

Where Each One Wins

Based on the recorded data, the Core 9 273PTE wins outright in every measured category simply because it has measurements. The Ultra 7 155UL has no benchmark scores in the database, so no performance wins can be attributed to it from the data.

The Core 9 273PTE shows particular strength in multi-threaded workloads. Its 24 threads against the Ultra 7 155UL's 14 threads gives it a 10-thread advantage, which should translate to superior parallel processing capability. The Cinebench R23 multi-core score of 20445 reflects this thread advantage. The 36 MB L3 cache further supports multi-threaded scenarios where shared data access is frequent.

Single-thread performance favors the Core 9 273PTE due to its 5.50 GHz boost clock, a full 0.70 GHz higher than the Ultra 7 155UL's 4.80 GHz. The Cinebench R23 single-core score of 2886 and PassMark single-thread score of 3433 quantify this capability.

The Ultra 7 155UL does hold advantages in specific areas, though these are architectural rather than performance-based. Its 15 W TDP is one-third of the Core 9 273PTE's 45 W TDP, indicating substantially lower power draw for thermally constrained systems. Its 7 nm process node is more advanced than the 10 nm node of the Core 9 273PTE, potentially improving power efficiency. The Arc Xe-LPG 64EU integrated graphics likely provide better GPU performance than UHD Graphics 730, though no benchmark data confirms this.

ECC memory support on the Core 9 273PTE makes it suitable for error-sensitive workloads, while the Ultra 7 155UL lacks this capability. The Core 9 273PTE's PCIe Gen 5 with 16 lanes supports high-bandwidth storage and GPU configurations, whereas the Ultra 7 155UL's PCIe Gen 4 with 8 lanes is more limited.

The Verdict

The data clearly separates these two processors into different usage profiles. The Intel Core 9 273PTE delivers substantial measured performance: an average benchmark score of 31143, an 82nd percentile ranking, and Cinebench R23 results of 20445 multi-core and 2886 single-core. Its 24 threads, 5.50 GHz boost clock, and 36 MB L3 cache position it for demanding multi-threaded and single-threaded workloads alike. The nearest rival data confirms it operates at parity with processors like the Intel Core i7-12700F and AMD Ryzen 9 8945HS, with deltas of 0.2% in both cases.

The Intel Core Ultra 7 155UL offers no measured performance data, making any performance claim unsupportable from the database. Its advantages are architectural: 15 W TDP for low-power systems, 7 nm process node, and Arc Xe-LPG 64EU integrated graphics. The 14-thread count and 12 MB L3 cache limit its multi-threaded ceiling relative to the Core 9 273PTE.

The Core 9 273PTE suits users who need verified performance across Cinebench and PassMark workloads, particularly where thread count and cache capacity matter. The Ultra 7 155UL suits systems prioritizing low power consumption and newer integrated graphics, accepting the absence of benchmark validation. The socket difference (1700 versus 1851) means platform choice largely determines which processor is viable, and the launch MSRP of $549 for the Core 9 273PTE versus $426 for the Ultra 7 155UL reflects their different positioning. The recorded data supports the Core 9 273PTE as the higher-performance option, with the Ultra 7 155UL remaining an unmeasured quantity in the database.
