Architecture Differences

The two processors come from different Intel design lineages. The Intel Core 5 223PTE uses the Bartlett Lake codename, built on a 10 nm process by Intel, and is a desktop part on Intel Socket 1700. The Intel Core Ultra 7 255H is from the Arrow Lake-H family, part of the Core Ultra Series 2, built on a 3 nm process by TSMC, and is a mobile part on Intel BGA 2049.

Core counts differ significantly. The Core 5 223PTE offers 8 cores and 16 threads, indicating a conventional hyperthreading design. The Core Ultra 7 255H packs 16 cores but also 16 threads, which suggests a hybrid core arrangement without hyperthreading across all cores. Cache structures also diverge. The Core 5 has 80 KB L1 per core, 2 MB L2 per core, and 24 MB shared L3. The Ultra 7 has 192 KB L1 per core, 3 MB L2 per core, and the same 24 MB shared L3. The larger per-core cache on the Ultra 7 likely helps with data locality.

Memory support differs. The Core 5 supports DDR4 and DDR5, while the Ultra 7 supports DDR5 and LPDDR5X. The Ultra 7 also has higher peak memory bandwidth at 102.4 GB/s versus 89.6 GB/s. Both support ECC memory. PCIe lanes differ as well: the Core 5 provides Gen 5 with 16 lanes (CPU only), while the Ultra 7 provides Gen 5 with 20 lanes (CPU only). Integrated graphics are distinct, with UHD Graphics 770 on the desktop part and Arc Graphics 140T on the mobile part.

The production status for both is active. The Core 5 223PTE has a launch MSRP of $232 and was released in March 2026. The Ultra 7 255H has no launch MSRP recorded and was released in January 2025. Both have locked multipliers.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, but the Intel Core Ultra 7 255H carries a full set of recorded benchmark results. The Intel Core 5 223PTE has no benchmark entries. Therefore, all quantitative comparisons come from the Ultra 7's scores and its nearest rivals.

Starting with Cinebench, the Ultra 7 255H scores 1515 in Cinebench R15 multi-core and 251 in single-core. In Cinebench R20, it reaches 6381 multi-core and 900 single-core. In Cinebench R23, the multi-core score is 9240 and single-core is 1843. These numbers place the Ultra 7 well above the 50th percentile where the Core 5 sits, given that the Ultra 7 ranks at the 83rd percentile overall.

Geekbench results show 14024 multi-core and 2335 single-core for the Ultra 7. PassMark tests provide a detailed picture: multithread score of 30703, single thread score of 4317, integer math at 77975, floating point math at 98796, data compression at 298850, data encryption at 23395, extended instructions at 23755, find prime numbers at 303, physics at 2254, and random string sorting at 36058.

The nearest rivals for the Ultra 7 255H include the AMD Ryzen 5 240 with an average score of 33542 and a delta of 0%, meaning the Ultra 7 is essentially tied. The AMD Ryzen 7 8840HS averages 33667, which is 0.4% higher than the Ultra 7. The AMD Ryzen 5 7645HX also averages 33668, again 0.4% higher. The Intel Core i5-12600HX averages 33375, which is 0.5% lower. These deltas are small, indicating the Ultra 7 sits in a highly competitive cluster.

Because the Core 5 223PTE has no benchmark scores, the data cannot show a direct head-to-head win for either side. What the data does show is that the Ultra 7 255H is a high-performing mobile processor at the 83rd percentile, while the Core 5 223PTE is at the 50th percentile with no recorded performance data.

Specification Differences

The two processors differ across nearly every specification field. The Core 5 223PTE has 8 cores and 16 threads, while the Ultra 7 255H has 16 cores and 16 threads. Base clocks are 2.30 GHz versus 2.00 GHz; boost clocks are 5.40 GHz versus 5.10 GHz. Thermal design power is 45 watts for the Core 5 and 28 watts for the Ultra 7.

Sockets differ entirely: Intel Socket 1700 for the Core 5, Intel BGA 2049 for the Ultra 7. The Core 5 uses the Bartlett Lake codename on a 10 nm process from Intel. The Ultra 7 uses the Arrow Lake codename, part of Arrow Lake-H architecture, on a 3 nm process from TSMC. The Ultra 7 belongs to the Core Ultra Series 2 generation.

Cache layouts differ: L1 is 80 KB per core on the Core 5 versus 192 KB per core on the Ultra 7. L2 is 2 MB per core versus 3 MB per core. L3 is 24 MB shared on both. Memory support: DDR4 and DDR5 on the Core 5, DDR5 and LPDDR5X on the Ultra 7. Memory bandwidth is 89.6 GB/s versus 102.4 GB/s. Both support dual-channel memory and ECC.

PCIe connectivity differs: 16 lanes of Gen 5 on the Core 5, 20 lanes of Gen 5 on the Ultra 7. Integrated graphics are UHD Graphics 770 versus Arc Graphics 140T. Market segments are Desktop for the Core 5 and Mobile for the Ultra 7. Release dates are March 2026 for the Core 5 and January 2025 for the Ultra 7. The Core 5 has a launch MSRP of $232; the Ultra 7 has no launch MSRP. Both are active production parts with locked multipliers.

The Verdict

The data shows a clear performance hierarchy. The Intel Core Ultra 7 255H sits at the 83rd percentile among all CPUs, with an average benchmark score of 33537. The Intel Core 5 223PTE sits at the 50th percentile with no recorded benchmarks. That percentile gap alone indicates the Ultra 7 is designed for significantly higher throughput.

The Ultra 7 255H also benefits from a more advanced 3 nm process from TSMC, compared to the 10 nm process on the Core 5. It has double the core count, larger per-core caches, and higher memory bandwidth. These architectural advantages translate into the recorded scores in Cinebench, Geekbench, and PassMark. The Core 5 223PTE counters with a higher boost clock of 5.40 GHz and a higher base clock of 2.30 GHz, but the data provides no benchmark results to confirm how that clock advantage translates into real-world performance.

The Core 5 223PTE is a desktop part with a 45-watt TDP, a launch MSRP of $232, and support for DDR4 and DDR5 memory. The Ultra 7 255H is a mobile part with a 28-watt TDP, no launch MSRP, and support for DDR5 and LPDDR5X. For any workload where measured performance matters, the Ultra 7 255H is the clear choice based on its 83rd percentile ranking and comprehensive benchmark scores. The Core 5 223PTE, without any scores, cannot be validated as a competitor in the same performance class.

Where Each One Wins

The Intel Core Ultra 7 255H wins on every measured performance metric in the database. Its Cinebench R23 multi-core score of 9240 and single-core score of 1843 indicate strong rendering capability. Geekbench scores of 14024 multi-core and 2335 single-core show solid general-purpose compute. PassMark results, including 30703 multithread and 4317 single thread, confirm balanced performance across integer math, floating point math, data compression, encryption, and physics workloads. The 83rd percentile ranking places it above the vast majority of CPUs.

The Intel Core 5 223PTE has no benchmark scores, so the database cannot confirm any workload where it wins. Its specifications suggest it may favor single-thread speed due to the 5.40 GHz boost clock, but no measurements exist to verify that. Its 45-watt TDP and desktop socket indicate it is intended for stationary systems, while the Ultra 7's 28-watt TDP and BGA socket target mobile platforms.

For users prioritizing raw measured performance, the Ultra 7 255H delivers across rendering, general compute, and data-heavy tasks. For users needing a desktop part with DDR4 support and a known launch MSRP of $232, the Core 5 223PTE offers a lower core count and a higher clock speed on paper, but without benchmark evidence, its real-world standing remains unverified. The Ultra 7 255H also provides more PCIe lanes (20 versus 16), larger per-core caches, and higher memory bandwidth, which supports workloads that benefit from data throughput and parallel execution.
