Intel Core 5 223PTE vs Intel Core Ultra 7 366H Comparison

Intel Core 5 223PTE and Intel Core Ultra 7 366H occupy different corners of the processor market, and the recorded data shows a clear split in their intended use cases. The Core 5 223PTE is a desktop part with a 45 W TDP, while the Core Ultra 7 366H is a mobile processor with a 25 W TDP. The benchmark results and architectural specifications place them in distinct performance tiers, with the Ultra 7 366H dominating in raw compute and the Core 5 223PTE offering a desktop-oriented feature set.

Where Each One Wins

The Core Ultra 7 366H wins every recorded benchmark in the database. It holds a percentile rank of 87 among all CPUs, while the Core 5 223PTE sits at the 50th percentile. This means the Ultra 7 366H outperforms 87% of all processors in the database, whereas the Core 5 223PTE is exactly average. The Ultra 7 366H has an average benchmark score of 41263, while the Core 5 223PTE has an average benchmark score of 0 in the database, indicating no recorded performance tests for the desktop chip.

The Core Ultra 7 366H’s wins are comprehensive across all tested workloads. In Cinebench R23 multi-core, it scores 28477, and in single-core, it scores 4020. PassMark tests further confirm its dominance: it scores 33429 in multithread, 4043 in single thread, 103615 in floating point math, and 83695 in integer math. The Core 5 223PTE has no recorded benchmark scores, so the database shows no wins for it in any category.

The use-case split is therefore simple: the Ultra 7 366H is the compute leader for any workload that benefits from high core counts and modern architecture. The Core 5 223PTE, lacking benchmark data, cannot claim any performance advantage in the database. Its strengths lie in its desktop platform features, such as ECC memory support and a higher boost clock of 5.40 GHz, but these do not translate into recorded performance wins.

Architecture Differences

The architectural gap between these two processors is substantial. The Core Ultra 7 366H uses the Panther Lake architecture on a 3 nm process node, while the Core 5 223PTE uses the Bartlett Lake architecture on a 10 nm process node. The Ultra 7 366H is part of the Core Ultra Series 3, generation Ultra 7 (Panther Lake-H), while the Core 5 223PTE is from the Core 5 (Bartlett Lake) generation.

Core counts differ significantly: the Ultra 7 366H has 16 cores and 16 threads, whereas the Core 5 223PTE has 8 cores and 16 threads. The Ultra 7 366H therefore has double the physical cores, which explains its multi-core performance advantage. Cache hierarchies also diverge: the Ultra 7 366H has 192 KB L1 per core and 2.5 MB L2 per core, with 18 MB shared L3. The Core 5 223PTE has 80 KB L1 per core and 2 MB L2 per core, with 24 MB shared L3. The Ultra 7 366H has more per-core cache, while the Core 5 223PTE has more total L3 cache.

Memory support differs as well. The Core 5 223PTE supports DDR4 and DDR5, while the Ultra 7 366H supports DDR5 and LPDDR5X. Both use dual-channel memory buses, but the Ultra 7 366H has a higher memory bandwidth of 115.2 GB/s versus 89.6 GB/s for the Core 5 223PTE. ECC memory is supported only on the Core 5 223PTE, a feature that matters for desktop workstation use. PCIe lanes also differ: the Core 5 223PTE has 16 Gen 5 lanes (CPU only), while the Ultra 7 366H has 12 Gen 5 lanes (CPU only).

Integrated graphics differ: the Core 5 223PTE uses UHD Graphics 770, while the Ultra 7 366H uses Intel Xe3 Graphics. The Ultra 7 366H’s newer architecture and graphics solution reflect its mobile positioning, while the Core 5 223PTE relies on a desktop-oriented integrated solution.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two processors. However, the recorded scores for the Core Ultra 7 366H provide a full picture of its performance. In Cinebench R15, it scores 2870 in multi-core and 405 in single-core. In Cinebench R20, it scores 11960 in multi-core and 1688 in single-core. These results show consistent scaling across Cinebench versions, with multi-core scores increasing proportionally to the test’s workload demands.

PassMark results for the Ultra 7 366H reveal specialized strengths. Data compression scores 327455, while data encryption scores 25845. Extended instructions score 26901, and find prime numbers scores 326. Floating point math scores 103615, integer math scores 83695, and random string sorting scores 39814. Physics scores 2880, and multithread scores 33429. The single thread score of 4043 matches the singlethread score of 4043, confirming consistency across duplicate test entries.

The Core 5 223PTE has no benchmark scores in the database, so no direct comparison numbers exist. The nearest rivals for the Ultra 7 366H provide context: the Intel Core Ultra 7 356H scores 41215 (0.1% higher delta), the AMD Ryzen AI 5 PRO 440 scores 41208 (0.1% higher delta), the AMD Ryzen 9 5900X scores 41376 (0.3% lower delta), and the Intel Core Ultra X7 358H scores 40967 (0.7% higher delta). These deltas show the Ultra 7 366H is essentially tied with its closest competitors, all within a 1% performance band.
