Intel Core 5 223PE vs Intel Core Ultra 7 265F

The Intel Core Ultra 7 265F dominates the Intel Core 5 223PE across every recorded benchmark in the database. The Core Ultra 7 265F wins all 17 head-to-head comparisons, with the Core 5 223PE recording zero wins. The average benchmark score for the Core Ultra 7 265F is 64438, placing it in the 93rd percentile of all CPUs, while the Core 5 223PE averages 40585 and sits in the 87th percentile. The magnitude of the performance gap varies significantly depending on the workload, from a modest 11.2% difference in single-threaded tests to a 61.8% deficit in prime number finding.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent 37% advantage for the Core Ultra 7 265F across all six tests. In Cinebench R15 multicore, the Core Ultra 7 265F scores 4231 against 2666 for the Core 5 223PE. The single-core R15 result follows the same pattern: 597 versus 376. Moving to Cinebench R20, the multicore scores are 17631 and 11111, while single-core records 2488 and 1568. In Cinebench R23, the most demanding of the series, the Core Ultra 7 265F reaches 41980 multicore and 5926 single-core, compared to 26455 and 3734 for the Core 5 223PE. The identical 37% delta across all Cinebench versions suggests the performance difference scales uniformly with workload intensity and thread count.

PassMark results reveal a wider spread. Data compression favors the Core Ultra 7 265F by 31.6%, with scores of 507018 versus 346623. Integer math shows the smallest multi-threaded gap at 27.7%, with 138078 against 99819. The single-thread PassMark test records 4750 for the Core Ultra 7 265F and 4219 for the Core 5 223PE, an 11.2% difference that reflects the closer single-core clock and architecture relationship between the two processors.

The largest deltas appear in workloads that stress parallel execution or specialized instruction paths. Floating point math delivers 173855 for the Core Ultra 7 265F against 76468 for the Core 5 223PE, a 56% gap. Data encryption shows a 53.3% difference (39468 versus 18448). Random string sorting runs 42.7% faster on the Core Ultra 7 265F (62439 versus 35798). Extended instructions score 39235 versus 24672, a 37.1% difference. Prime number finding produces the most lopsided result: 416 versus 159, meaning the Core Ultra 7 265F completes this task 61.8% faster. Physics simulation shows a 21.4% gap (3172 versus 2493), and multithread PassMark records 49410 versus 31124, a 37% difference.

The Core 5 223PE never closes the gap below 11.2% in any test. The single-thread PassMark result is its closest contest, which indicates that per-core performance is more comparable than aggregate throughput. Still, the Core Ultra 7 265F leads even there, so the Core 5 223PE cannot claim a single workload category.

Architecture Differences

The two processors come from fundamentally different design generations. The Core 5 223PE uses the Bartlett Lake codename and belongs to the Core 5 generation, built on a 10 nm process at Intel's own foundry. It has 8 cores and 16 threads, with a base clock of 2.90 GHz and a boost clock of 5.20 GHz. The Core Ultra 7 265F uses the Arrow Lake-S codename under the Arrow Lake architecture, part of the Core Ultra Series 2 generation, fabricated on a 3 nm node by TSMC. It packs 20 cores and 20 threads, with a base clock of 2.40 GHz and a boost clock of 5.30 GHz.

The transistor count and die size differ sharply. The Core Ultra 7 265F contains 17,800 million transistors on a 243 mm² die, while the database records no transistor or die size figures for the Core 5 223PE. The cache hierarchy also diverges. The Core 5 223PE has 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The Core Ultra 7 265F provides 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The larger per-core L1 and L2 caches on the Core Ultra 7 265F likely contribute to its single-thread advantage, while the additional L3 capacity helps with shared data across its 20 cores.

Memory support separates the two as well. The Core 5 223PE supports both DDR4 and DDR5, while the Core Ultra 7 265F supports DDR5 only. Both use dual-channel memory buses, but the Core Ultra 7 265F achieves 102.4 GB/s memory bandwidth against 89.6 GB/s for the Core 5 223PE. The Core 5 223PE supports ECC memory; the Core Ultra 7 265F does not.

PCIe lanes differ: the Core 5 223PE provides Gen 5 with 16 lanes from the CPU, while the Core Ultra 7 265F offers Gen 5 with 20 lanes. Integrated graphics also split the pair. The Core 5 223PE includes UHD Graphics 730, while the Core Ultra 7 265F has no integrated graphics, marked as N/A. Both processors have locked multipliers and carry active production status. The Core 5 223PE targets the Desktop segment, as does the Core Ultra 7 265F. The Core 5 223PE uses Intel Socket 1700, while the Core Ultra 7 265F requires Intel Socket 1851.

The Verdict

The recorded data shows a clear hierarchy. The Core Ultra 7 265F outperforms the Core 5 223PE in every benchmark, with an average score nearly 59% higher (64438 versus 40585). Its percentile ranking of 93 versus 87 confirms that it sits in a higher performance tier within the database's CPU population. The Core 5 223PE's nearest rivals include the Intel Core 7 253PE at 40557 (0.1% lower), the Intel Core Ultra X7 368H at 40518 (0.2% lower), and the Intel Xeon 6357P at 40630 (0.1% higher), placing it in a tight cluster around 40500-40630. The Core Ultra 7 265F's nearest rivals are the Intel Core Ultra 7 265 at 64640 (0.3% higher), the AMD EPYC 4464P at 64823 (0.6% higher), and the Intel Core i9-13900KS at 64051 (0.6% lower), showing it competes with far more powerful processors.

For workloads that depend on multi-threaded throughput, such as video rendering, data compression, or scientific computation, the Core Ultra 7 265F's 20 cores and 20 threads provide a decisive advantage over the Core 5 223PE's 8 cores and 16 threads. The Cinebench multicore results, which all show a 37% gap, directly reflect this core count difference. The Core 5 223PE, with its lower core count but higher base clock (2.90 GHz versus 2.40 GHz), cannot compensate for the Core Ultra 7 265F's architectural advantages. Even in single-threaded tests, where the Core 5 223PE's higher base clock might help, the Core Ultra 7 265F still leads by 11.2% in PassMark single-thread and 37% in Cinebench single-core tests.

The Core 5 223PE does offer ECC memory support and integrated graphics, features absent from the Core Ultra 7 265F. It also supports DDR4, which could matter for systems with existing DDR4 memory. These features do not appear in the benchmark scores, but they define the Core 5 223PE's role for specific use cases. The Core Ultra 7 265F, by contrast, trades those features for raw performance and a newer platform.
