The average benchmark scores reflect the overall gap. The Ultra 5 235A posts an average score of 48201, placing it in the 90th percentile of all CPUs. The Core 5 223PE averages 40585, sitting in the 87th percentile. The nearest rivals for the Ultra 5 include the AMD Ryzen AI Max PRO 380 at 48171 (0.1% behind) and the Intel Core Ultra 5 245HX at 48287 (0.2% ahead). The Core 5 223PE sits within 0.3% of the Intel Core 7 253PE and the AMD Ryzen AI 5 PRO 435G, showing it is closely clustered with its direct competitors.

Architecture Differences

The two processors come from different design lineages. The Core 5 223PE uses the Bartlett Lake codename built on a 10 nm process at Intel's own foundry. The Core Ultra 5 235A uses the Arrow Lake architecture, specifically Arrow Lake-S, built on a 3 nm process at TSMC. The process node difference is substantial, with the Ultra 5 using a significantly smaller manufacturing process.

Core and thread counts differ markedly. The Core 5 223PE has 8 cores and 16 threads, while the Ultra 5 235A has 14 cores and 14 threads. The Ultra 5 has more physical cores but no hyperthreading support, resulting in fewer total threads. The Core 5 relies on simultaneous multithreading to reach 16 threads from 8 cores.

Cache hierarchies also differ. The Core 5 223PE has 80 KB of L1 cache per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The Ultra 5 235A has 192 KB of L1 per core, 3 MB of L2 per core, and the same 24 MB of shared L3. The Ultra 5 provides more cache per core at each level. The Ultra 5 also has a documented transistor count of 17,800 million and a die size of 243 mm², while the Core 5 has no recorded transistor or die size data.

Clock speeds favor different metrics. The Core 5 223PE has a base clock of 2.90 GHz and a boost clock of 5.20 GHz. The Ultra 5 235A has a higher base clock of 3.40 GHz but a lower boost clock of 5.00 GHz. The higher boost on the Core 5 does not translate into higher single-core benchmark scores, as the Ultra 5 wins all single-core tests.

Memory support diverges. The Core 5 223PE supports both DDR4 and DDR5 memory with dual-channel access and a memory bandwidth of 89.6 GB/s. The Ultra 5 235A supports only DDR5, also dual-channel, with a higher memory bandwidth of 102.4 GB/s. ECC memory is supported on the Core 5 but not on the Ultra 5.

PCIe connectivity differs. The Core 5 223PE provides Gen 5 with 16 lanes from the CPU, while the Ultra 5 235A provides Gen 5 with 20 lanes. The integrated graphics differ as well: the Core 5 uses UHD Graphics 730, while the Ultra 5 uses Arc Xe-LPG Graphics 24EU.

Where Each One Wins

The Intel Core Ultra 5 235A dominates rendering and content creation workloads. The Cinebench R15, R20, and R23 results across both multicore and single-core tests all favor the Ultra 5 with a consistent 18.9% margin. The PassMark multithread score confirms this pattern with another 18.9% lead. For users running CPU renderers, video encoders, or other threaded creative applications, the data consistently favors the Ultra 5.

The Ultra 5 also leads in encryption and compression tasks. Data encryption shows a 38.8% advantage, data compression shows a 12% lead, and random string sorting shows a 27.7% advantage. These results indicate stronger performance in archival, database, and security-related workloads. The find prime numbers test gives the Ultra 5 its largest win at 59.4%, suggesting a significant advantage in primality testing and related mathematical workloads.

The Intel Core 5 223PE wins in two areas. Integer math shows a 12.6% advantage over the Ultra 5, indicating that pure integer arithmetic operations run faster on the Core 5 despite its older architecture. Physics simulation gives the Core 5 a 2.3% edge, a smaller but still positive result for physics-based calculations.

The single-core comparison deserves attention. The Ultra 5 leads PassMark single-thread by 7.4% and Cinebench R23 single-core by 18.9%. This consistency across single-thread tests indicates that the Ultra 5 provides better responsiveness in lightly threaded applications such as everyday desktop use, legacy software, and games that rely on a few fast cores.
