Architecture Differences

The two processors come from different architectural lineages and target different market segments. The Intel Core 5 223PTE is a desktop part based on the Bartlett Lake codename, built on a 10 nm process. It uses the Intel Socket 1700 platform and belongs to the Core 5 (Bartlett Lake) generation. In contrast, the Intel Core Ultra 5 338H is a mobile processor from the Panther Lake architecture, built on a 3 nm process, and uses the Intel BGA 2540 socket. It belongs to the Ultra 5 (Panther Lake-H) generation and is part of the Core Ultra Series 3 family.

Cache hierarchy differs notably between the two. The Core 5 223PTE provides 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. The Core Ultra 5 338H offers a larger L1 cache at 192 KB per core and 2.5 MB of L2 cache per core, but a smaller shared L3 cache at 18 MB. These cache configurations reflect the different core architectures and power envelopes.

Memory support also separates the two. The Core 5 223PTE supports both DDR4 and DDR5 memory in a dual-channel configuration, with a memory bandwidth of 89.6 GB/s. The Core Ultra 5 338H exclusively supports LPDDR5X memory, also dual-channel, but with a higher bandwidth of 136.5 GB/s. The mobile part has a lower TDP of 25 watts compared to the desktop part's 45 watts.

PCIe connectivity differs as well. The Core 5 223PTE provides Gen 5 with 16 lanes (CPU only), while the Core Ultra 5 338H provides Gen 5 with only 4 lanes (CPU only). Integrated graphics also differ: the desktop chip uses UHD Graphics 770, whereas the mobile chip uses Arc B370. The Core 5 223PTE also supports ECC memory, a feature absent on the Core Ultra 5 338H.

Head-to-Head Benchmarks

The database contains detailed benchmark results only for the Intel Core Ultra 5 338H; no benchmark scores are recorded for the Intel Core 5 223PTE. This means the head-to-head comparison must rely on the recorded performance of the mobile part and its position relative to other CPUs in the database.

The Core Ultra 5 338H delivers strong multi-threaded results. In Cinebench R15 multicore, it scores 2504 points. Cinebench R20 multicore shows 10213 points, and Cinebench R23 multicore reaches 16331 points. Single-threaded scores are also solid: 305 points in Cinebench R15, 1441 points in Cinebench R20, and 2044 points in Cinebench R23.

PassMark results for the Core Ultra 5 338H cover a range of workloads. Data compression scores 276539, data encryption scores 21367, and extended instructions score 23906. Prime number finding scores 304, floating point math scores 84067, and integer math scores 64934. The multithread score is 28717, physics scores 2697, and random string sorting scores 34082. Single-thread performance is recorded at 4180.

With an average benchmark score of 33989, the Core Ultra 5 338H sits in the 84th percentile of all CPUs. Its nearest rivals in the database provide context for its performance. The Intel Core Ultra 7 165H has an average score of 34083, which is 0.3% higher than the Core Ultra 5 338H. The Intel Core i7-12800HX scores 33875, 0.3% lower. The Intel Xeon 6353P scores 33844, 0.4% lower, and the AMD EPYC 4244P scores 34220, which is 0.7% higher. These small deltas indicate the Core Ultra 5 338H performs in a tight competitive band, essentially matching higher-tier mobile and desktop parts from previous generations.

Since no benchmark data exists for the Core 5 223PTE, the database cannot provide direct head-to-head scores between the two chips. The analysis must instead rely on architectural differences and the known performance class of the Core Ultra 5 338H.

Where Each One Wins

The Intel Core 5 223PTE offers advantages in several areas based on its specification profile. Its higher boost clock of 5.40 GHz suggests an edge in lightly threaded workloads where single-core frequency dominates. The 16 threads provide better multitasking capability for parallel desktop applications. The larger 24 MB L3 cache can benefit workloads with high cache reuse. ECC memory support makes it suitable for reliability-focused desktop environments. The 16 PCIe Gen 5 lanes provide substantial expansion bandwidth for discrete GPUs or storage devices. Its desktop platform with a 45 W TDP indicates a design for sustained performance rather than power efficiency.

The Intel Core Ultra 5 338H, conversely, wins on power efficiency and portability. Its 25 W TDP is nearly half that of the desktop part, making it suitable for thin-and-light mobile systems. The 3 nm process node indicates a more advanced manufacturing technology, which typically correlates with improved power efficiency. The higher memory bandwidth of 136.5 GB/s, enabled by LPDDR5X support, benefits memory-intensive applications. The larger L1 and L2 caches per core may improve per-core performance in latency-sensitive workloads. Its 84th percentile ranking and average benchmark score of 33989 place it in a competitive performance class among all CPUs in the database.

The mobile part also demonstrates strong recorded performance across Cinebench and PassMark tests, with particularly notable results in data compression (276539) and floating point math (84067). Its nearest rivals, including the Intel Core Ultra 7 165H and Intel Core i7-12800HX, show performance within 0.4% of the Core Ultra 5 338H, indicating the chip competes effectively with higher-tier processors.

The Verdict

The data indicates a clear separation of roles between these two processors. The Intel Core 5 223PTE targets desktop systems where raw frequency, thread count, and expansion capability matter. Its 5.40 GHz boost clock and 16 threads serve workloads that scale with single-core speed and parallel execution. The 16 PCIe Gen 5 lanes and ECC memory support position it for desktop builds requiring high-bandwidth components and data integrity. However, the database contains no benchmark scores for this part, so its actual measured performance remains unrecorded.

The Intel Core Ultra 5 338H targets mobile systems where power efficiency and portability take precedence. Its 25 W TDP and 3 nm process enable longer battery life and thinner chassis. The recorded benchmark data shows a capable processor: 16331 points in Cinebench R23 multicore and 4180 in PassMark single-thread, ranking in the 84th percentile of all CPUs. Its performance sits within 0.7% of rivals like the AMD EPYC 4244P and Intel Core Ultra 7 165H, confirming it delivers competitive computing power despite its mobile orientation.

Users requiring a desktop processor with high boost clocks, ECC support, and extensive PCIe lanes should favor the Intel Core 5 223PTE. Users needing a power-efficient mobile processor with proven benchmark performance should favor the Intel Core Ultra 5 338H. The choice hinges on platform and usage context rather than direct performance superiority, as the database provides measurable results only for the mobile chip.
