Intel Core 5 223PTE vs Intel Core Ultra 7 356H Comparison

Head-to-Head Benchmarks

The Intel Core Ultra 7 356H has a decisive advantage in the recorded benchmark data, with the Intel Core 5 223PTE lacking any benchmark entries in the database. The Core Ultra 7 356H delivers a Cinebench R23 multi-core score of 18395 and a single-core score of 2040. Its Cinebench R20 results show 12153 in multi-core and 1715 in single-core, while Cinebench R15 records 3055 and 303 respectively. The gap between these two processors cannot be quantified directly because no comparable scores exist for the Core 5 223PTE.

The Core Ultra 7 356H also posts substantial PassMark results. Its multi-thread score of 33978 places it well ahead of typical mainstream processors, and its single-thread score of 4072 confirms strong per-core performance. Data compression reaches 336177, while encryption scores 26345. Floating point math hits 103128, integer math lands at 83111, and extended instructions reach 27898. The physics score of 2895 and random string sorting at 40990 round out the suite. Prime number finding is the weakest result at 327, but that still reflects a capable execution engine.

The Core Ultra 7 356H holds an average benchmark score of 41215, placing it at the 87th percentile of all CPUs in the database. The Core 5 223PTE, by contrast, sits at the 50th percentile with an average benchmark score of 0, meaning no measured workload data supports its position. The Core Ultra 7 356H compares closely with the AMD Ryzen AI 5 PRO 440, which averages 41208 for a delta of 0 percent. It trails the Intel Core Ultra 7 366H by 0.1 percent (41263) and the AMD Ryzen 9 5900X by 0.4 percent (41376), while leading the Intel Core Ultra X7 358H by 0.6 percent (40967). These margins are narrow, confirming that the Core Ultra 7 356H competes at the top of its immediate performance tier.

Because the Core 5 223PTE has no recorded scores, the head-to-head comparison is one-sided. The data indicates that any workload run on the Core Ultra 7 356H would have a measurable result, while the Core 5 223PTE cannot be assessed from the database.

Architecture Differences

The two processors come from different Intel design families. The Core 5 223PTE uses the Bartlett Lake codename with a 10 nm process node, while the Core Ultra 7 356H uses the Panther Lake architecture on a 3 nm node. Both are fabricated by Intel, but the process difference is substantial: the 3 nm node allows tighter transistor density and lower power draw per operation.

The core configurations diverge sharply. The Core 5 223PTE has 8 cores and 16 threads, while the Core Ultra 7 356H has 16 cores and 16 threads. The thread count being equal despite double the cores indicates that the Core Ultra 7 356H uses a hybrid layout where not every core contributes an additional thread. The Core 5 223PTE follows a traditional symmetric thread scheme.

Cache hierarchies also differ. The Core 5 223PTE provides 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The Core Ultra 7 356H offers 192 KB of L1 per core, 2.5 MB of L2 per core, but only 18 MB of shared L3. The Core Ultra 7 356H has more L1 and L2 per core, which helps latency-sensitive single-thread work, while the Core 5 223PTE has more L3 capacity for larger shared working sets.

The Core 5 223PTE runs at a base clock of 2.30 GHz and boosts to 5.40 GHz. The Core Ultra 7 356H runs at 1.90 GHz base and boosts to 4.70 GHz. Despite the lower clocks, the Core Ultra 7 356H achieves higher benchmark scores, indicating that architectural efficiency and the 3 nm process overcome the raw clock disadvantage.

The Core 5 223PTE supports DDR4 and DDR5 memory with dual-channel access and 89.6 GB/s of bandwidth. The Core Ultra 7 356H supports DDR5 and LPDDR5X with dual-channel access and 115.2 GB/s of bandwidth. The Core Ultra 7 356H also has a wider PCIe implementation at Gen 5 with 12 lanes, while the Core 5 223PTE provides Gen 5 with 16 lanes. ECC memory is supported on the Core 5 223PTE but not on the Core Ultra 7 356H.

Integrated graphics differ as well. The Core 5 223PTE uses UHD Graphics 770, while the Core Ultra 7 356H uses Intel Xe3 Graphics. The Xe3 architecture represents a newer graphics generation with different feature support.

The Core 5 223PTE is a desktop part on Intel Socket 1700, while the Core Ultra 7 356H is a mobile part on Intel BGA 2540. The desktop chip has a 45 W TDP, and the mobile chip has a 25 W TDP. The Core 5 223PTE was released on 2026-03-08, while the Core Ultra 7 356H was released on 2026-01-04. The Core Ultra 7 356H belongs to the Core Ultra Series 3 and the Panther Lake-H generation, while the Core 5 223PTE belongs to the Core 5 (Bartlett Lake) generation.

Where Each One Wins

The Core Ultra 7 356H wins in every measured category because it is the only one of the two with benchmark data. Its multi-thread score of 33978 and Cinebench R23 multi-core of 18395 indicate strong parallel throughput, which suits rendering, video encoding, and simulation workloads. The single-thread scores of 4072 (PassMark) and 2040 (Cinebench R23) confirm that lightly threaded applications also run well.

The Core 5 223PTE cannot be assigned any benchmark wins from the database. Its higher boost clock of 5.40 GHz and 45 W TDP suggest it may favor sustained desktop workloads, but the absence of measured scores prevents any quantitative claim. Its larger 24 MB L3 cache could benefit workloads with large shared data sets, but no recorded test verifies that.

The Core Ultra 7 356H also has a clear mobility advantage. Its 25 W TDP and BGA 2540 socket are designed for laptops, while the Core 5 223PTE targets desktop systems. The Core Ultra 7 356H supports LPDDR5X memory, which is common in thin notebooks, and its 115.2 GB/s memory bandwidth exceeds the Core 5 223PTE's 89.6 GB/s. The newer Xe3 integrated graphics give the mobile chip a more modern display and media engine.

The Core 5 223PTE holds advantages in specific specifications. It supports ECC memory, which matters for error-sensitive computing environments. It has 16 PCIe Gen 5 lanes versus 12 on the Core Ultra 7 356H, offering more headroom for desktop expansion cards. Its 5.40 GHz boost clock is higher, and its 24 MB L3 cache is larger. These features are real differentiators, but they do not translate into benchmark wins without recorded scores.
