Single-thread performance also belongs to the Ultra 5, with 4339 versus 4219, a 2.8% lead in both PassMark single-thread tests.

Where Each One Wins

The data indicates distinct workload preferences. The Core 5 223PE excels in integer-heavy operations, data compression, and physics simulation. Its 18.5% lead in integer math and 17.5% lead in data compression suggest strong general-purpose compute throughput. The 15.6% advantage in PassMark physics points to solid performance in simulation workloads that rely on multi-threaded integer execution. The Cinebench results, though narrow, consistently favor the Core 5 across every version tested, indicating a reliable edge in rendering tasks.

The Ultra 5 235T shows superiority in encryption, prime number calculation, floating-point math, and single-threaded tasks. The 21.4% encryption win and 50% prime number win suggest a stronger cryptographic and algorithmic throughput. The 28.2% floating-point advantage indicates better execution of scientific and numerically intensive workloads. The 2.8% single-thread lead means the Ultra 5 handles lightly threaded applications more efficiently.

For users prioritizing database operations, compression, integer processing, or physics simulations, the Core 5 223PE delivers measurable advantages. For encryption, financial modeling, scientific computing, or single-thread responsiveness, the Ultra 5 235T holds the edge. The overall average benchmark score favors the Core 5, but the Ultra 5's specialized wins cover a different set of real-world tasks.

Architecture Differences

The two processors come from different Intel generations and foundries. The Core 5 223PE is built on a 10 nm process at Intel's own fabs, while the Ultra 5 235T uses a 3 nm process from TSMC. The Ultra 5 packs 17,800 million transistors on a 243 mm² die, while the Core 5 does not report transistor count or die size in the database.

Core configuration diverges sharply. The Core 5 223PE uses 8 cores with 16 threads, indicating hyper-threading support. The Ultra 5 235T has 14 cores but only 14 threads, meaning no hyper-threading. The Ultra 5 uses a hybrid Arrow Lake design with a mix of performance and efficiency cores. Cache structures differ: the Core 5 has 80 KB L1 per core and 2 MB L2 per core, while the Ultra 5 has 192 KB L1 per core and 3 MB L2 per core. Both share 24 MB L3.

Clock speeds favor the Core 5 in base frequency at 2.90 GHz versus 2.20 GHz, and boost frequency at 5.20 GHz versus 5.00 GHz. Both carry a 65 TDP. Memory support diverges: the Core 5 supports DDR4 and DDR5, while the Ultra 5 supports DDR5 only. Memory bandwidth also differs, with the Core 5 at 89.6 GB/s and the Ultra 5 at 102.4 GB/s. ECC memory is supported on the Core 5 but not on the Ultra 5.

PCIe lanes favor the Ultra 5 with Gen 5, 20 lanes versus Gen 5, 16 lanes on the Core 5. Integrated graphics differ as well: the Core 5 uses UHD Graphics 730, while the Ultra 5 uses Arc Xe-LPG Graphics 24EU. Sockets are incompatible: the Core 5 uses Intel Socket 1700, the Ultra 5 uses Intel Socket 1851. The Core 5 launched in March 2026 with a launch MSRP of $232, while the Ultra 5 launched in January 2025 with a launch MSRP of $247. Both are locked multipliers and actively in production.
