Passmark results include a multi-thread score of 36810, single-thread of 3650, integer math at 139410, floating point math at 107884, data encryption at 22719, extended instructions at 24630, physics at 3120, random string sorting at 45098, data compression at 405885, and find prime numbers at 203.

The Intel Processor U303L has no scores in any benchmark category. The database records an average benchmark score of 0 for this processor, and its percentile rank among all CPUs is 50. The Core 9 273PE holds a 90th percentile position among all CPUs, with an average benchmark score of 49845.

Comparing the Core 9 273PE to its nearest rivals in the database, the AMD Ryzen AI Max+ 388 posts an average score of 49796, a 0.1% advantage over the Core 9 273PE. The Intel Core i5-14600KF scores 49394, which is 0.9% behind. The Intel Core i9-13980HX leads with 50398, representing a 1.1% gap. The AMD Ryzen AI 9 HX PRO 370 scores 50448, 1.2% ahead. These deltas show the Core 9 273PE sits within a tight competitive band, essentially tied with the nearest rivals despite its strong absolute scores.

Since the U303L has no recorded benchmarks, no direct wins can be established for either processor in any workload. The data indicates the Core 9 273PE is a fully measured part with a complete performance profile, while the U303L remains uncharacterized in the database.

Architecture Differences

The two processors share the same 10 nm process node and Intel as the foundry, but their underlying designs diverge significantly. The Core 9 273PE uses the Bartlett Lake codename and belongs to the Core 9 (Bartlett Lake) generation. The U303L uses the Raptor Lake architecture with the Raptor Lake-PS codename, classified under the Intel Processor (Raptor Lake) generation.

Core counts differ substantially. The Core 9 273PE integrates 12 cores and 24 threads, while the U303L has 5 cores and 6 threads. Clock speeds also separate the two: the Core 9 273PE runs at a 2.30 GHz base clock and boosts to 5.70 GHz, whereas the U303L operates at 1.20 GHz base and 2.60 GHz boost. The Core 9 273PE carries a 65 W TDP, and the U303L is rated at 15 W.

Cache hierarchies are distinct. The Core 9 273PE provides 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The U303L offers the same 80 KB L1 per core but only 1.25 MB of L2 per core and 12 MB of shared L3. Memory support is identical in type, with both supporting DDR4 and DDR5 over dual-channel buses. The Core 9 273PE has a recorded memory bandwidth of 89.6 GB/s, while the U303L has no bandwidth figure in the database. ECC memory support is present on the Core 9 273PE but absent on the U303L.

PCIe connectivity differs by generation and lane count. The Core 9 273PE uses Gen 5 with 16 lanes from the CPU. The U303L uses Gen 4 with 8 lanes. Integrated graphics also differ: the Core 9 273PE includes UHD Graphics 730, while the U303L includes UHD Graphics 96EU. The Core 9 273PE targets the desktop market segment, and the U303L is aimed at mobile. Both processors are locked with no unlocked multiplier, and both production statuses are Active. The Core 9 273PE has a part number of SA4QD, and the U303L carries SRPKEQ5CV. Release dates show the U303L arrived earlier in the database on 2024-04-07, while the Core 9 273PE is dated 2026-03-08.

The Verdict

The data points to the Intel Core 9 273PE as the only processor in this comparison with a measurable performance profile. Its average benchmark score of 49845 places it in the 90th percentile of all CPUs, with nearest rivals within a 1.2% band. The Intel Processor U303L has no benchmark scores, an average score of 0, and a 50th percentile rank. These two processors occupy entirely different segments: the Core 9 273PE is a desktop part with 12 cores, 24 threads, a 5.70 GHz boost clock, and a 65 W TDP. The U303L is a mobile part with 5 cores, 6 threads, a 2.60 GHz boost clock, and a 15 W TDP.

The benchmark results indicate the Core 9 273PE is built for demanding multi-threaded workloads. Its Cinebench R23 multi-core score of 31288 and Passmark multi-thread score of 36810 confirm strong parallel throughput. The single-core R23 score of 4417 and Passmark single-thread of 3650 show capable single-thread performance as well. The U303L offers no recorded data to compare, so no performance claims can be made for it.

The architectural differences support the same conclusion. The Core 9 273PE has more cores, more threads, higher clocks, a larger L3 cache, faster PCIe, and ECC support. The U303L has fewer resources across every measurable dimension except its lower TDP, which suits a mobile market positioning. The Core 9 273PE also carries a launch MSRP of $549, while the U303L has a launch MSRP of $285. The database does not record any benchmark wins for either processor, so the verdict rests on the Core 9 273PE being the only part with verified performance data. Users with desktop workloads requiring multi-core throughput should look to the Core 9 273PE based on the recorded scores. The U303L remains a lower-power mobile option with no benchmark evidence in the database.
