Intel Core 9 273PE vs Intel Core Ultra 7 155HL Comparison

The Verdict

The Intel Core 9 273PE is the clear performance leader in this pairing. The database shows it sits at the 90th percentile among all CPUs, with an average benchmark score of 49845. The Intel Core Ultra 7 155HL, by contrast, sits at the 50th percentile with no recorded benchmark scores and an average score of zero. The Core 9 273PE is the only option here for anyone whose work or play depends on raw compute throughput, as its 12 cores and 24 threads, 5.70 GHz boost clock, and 36 MB of shared L3 cache give it a decisive structural advantage.

The Core Ultra 7 155HL is not without a role. It uses a 7 nm process node, draws 45 W, and carries the Arc Xe-LPG 128EU integrated graphics. For a desktop system where discrete GPU power is unnecessary, the Ultra 7 155HL has a lower TDP and a newer process node, which points toward better efficiency. But the data cannot confirm any performance benefit, since no benchmark results exist for it. The Core 9 273PE is the pick for compute-heavy tasks; the Ultra 7 155HL is the pick for a low-power desktop build that still needs modern integrated graphics.

Where Each One Wins

The Core 9 273PE wins every measurable category. Its Cinebench scores are strong across the board: 3153 in R15 multi-core, 445 in R15 single-core, 13140 in R20 multi-core, 1855 in R20 single-core, 31288 in R23 multi-core, and 4417 in R23 single-core. PassMark results reinforce this, with 36810 in multithread, 3650 in single-thread, 139410 in integer math, and 107884 in floating point math. The chip also delivers 405885 in data compression and 22719 in data encryption, which points to strong throughput in archiving and security workloads.

The Ultra 7 155HL has no recorded wins in the database. Its advantage is structural, not measured. It supports DDR5 memory (dependent on the motherboard), uses the newer 7 nm process, and integrates Arc Xe-LPG 128EU graphics, which is a more capable iGPU than the UHD Graphics 730 found on the Core 9 273PE. For a system that will not use a discrete GPU, the Ultra 7 155HL is the more sensible choice. For everything else, the Core 9 273PE takes the win.

Architecture Differences

The two chips come from different Intel design families. The Core 9 273PE is a Bartlett Lake part, built on a 10 nm process node, and uses the Intel Socket 1700 platform. It has 12 cores and 24 threads, meaning every core supports two threads. The Ultra 7 155HL is a Meteor Lake part, specifically Meteor Lake-PS, built on a 7 nm node, and uses the Intel Socket 1851 platform. It has 16 cores but only 22 threads, which indicates a hybrid arrangement where not all cores add a second thread.

Cache configurations also differ. The Core 9 273PE has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The Ultra 7 155HL has 112 KB of L1 per core, 2 MB of L2 per core, and only 24 MB of shared L3 cache. The Core 9 273PE has substantially more L3, which helps in workloads that repeatedly access a large working set.

Memory support differs as well. The Core 9 273PE supports both DDR4 and DDR5, while the Ultra 7 155HL supports DDR5 but the database notes that it depends on the motherboard. Both use a dual-channel memory bus at 89.6 GB/s. The Core 9 273PE supports ECC memory; the Ultra 7 155HL does not. PCIe connectivity is another split: the Core 9 273PE offers Gen 5 with 16 CPU lanes, while the Ultra 7 155HL offers Gen 4 with only 8 CPU lanes. The Core 9 273PE also has a higher base clock at 2.30 GHz versus 1.40 GHz, and a higher boost clock at 5.70 GHz versus 4.80 GHz.

The integrated graphics differ. The Core 9 273PE uses UHD Graphics 730, while the Ultra 7 155HL uses Arc Xe-LPG 128EU. The latter is a newer architecture and generally more capable, though the database does not provide iGPU benchmarks for either.

The Core 9 273PE was released on 2026-03-08, while the Ultra 7 155HL was released on 2024-04-07. Neither chip has an unlocked multiplier. The production status for both is Active.

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark results between these two CPUs. The Core 9 273PE has a full set of recorded scores; the Core Ultra 7 155HL has none. As a result, the comparison relies on the Core 9 273PE's absolute scores and its position relative to other CPUs in the database.

The Core 9 273PE's nearest rivals give context. Its average benchmark score of 49845 is 0.1% above the AMD Ryzen AI Max+ 388 (49796), 0.9% above the Intel Core i5-14600KF (49394), 1.1% below the Intel Core i9-13980HX (50398), and 1.2% below the AMD Ryzen AI 9 HX PRO 370 (50448). The Core 9 273PE therefore sits in a tight band around the 50000 average score mark, trading blows with high-end mobile and desktop parts from both Intel and AMD.

In Cinebench R23 multi-core, the Core 9 273PE scores 31288. In single-core R23, it scores 4417. The R20 results are 13140 multi-core and 1855 single-core. R15 results are 3153 multi-core and 445 single-core. These numbers indicate a chip that scales well with thread count and also has strong single-thread performance, which matters for lightly threaded applications.

PassMark results for the Core 9 273PE follow a similar pattern. Multithread score is 36810, single-thread is 3650, integer math is 139410, floating point math is 107884, extended instructions score is 24630, data compression is 405885, data encryption is 22719, random string sorting is 45098, physics is 3120, and prime number finding is 203. The data compression and encryption numbers are particularly strong, suggesting the chip handles workloads that involve large data movement and cryptographic operations with ease.

Because the Ultra 7 155HL has no benchmark entries, there is no measured comparison to make. The Core 9 273PE's 90th percentile ranking versus the Ultra 7 155HL's 50th percentile ranking is the only direct percentile comparison available, and it favors the Core 9 273PE by a wide margin.
