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

The Verdict

The recorded data splits these two desktop processors cleanly. The Intel Core Ultra 7 265 wins 15 of 17 head-to-head benchmark comparisons, while the Intel Core 5 223PE takes only 2. The Core Ultra 7 265 also sits higher in the overall percentile ranking, at 93 versus 87 for the Core 5 223PE. The average benchmark score difference is substantial: 64,640 for the Core Ultra 7 265 against 40,585 for the Core 5 223PE.

The Core 5 223PE is the choice only where the Cinebench R20 results matter most. It leads the Core Ultra 7 265 in R20 multi-core by 77.3 percent and in R20 single-core by 77.4 percent. Those are the sole wins in the entire comparison set. Every other test, from Cinebench R15 and R23 to the full PassMark suite, favors the Core Ultra 7 265.

For anyone building around the Intel Socket 1700 platform with DDR4 memory support, the Core 5 223PE offers a path that the Core Ultra 7 265 cannot match. The Core Ultra 7 265 requires Intel Socket 1851 and DDR5 exclusively. The data shows the Core Ultra 7 265 as the stronger performer in almost every measured workload, but the Core 5 223PE remains the only option here for those specific platform constraints.

Where Each One Wins

The Core 5 223PE wins exclusively in Cinebench R20. Its multi-core score of 11,111 beats the Core Ultra 7 265's 6,268 by 77.3 percent. Its single-core score of 1,568 beats 884 by 77.4 percent. This is a curious inversion, since the other two Cinebench versions (R15 and R23) go the opposite direction by large margins. The R20 result suggests a workload-specific advantage, possibly related to the Core 5's 16 threads versus the Core Ultra 7's 20 threads and differing architectural behavior under that particular renderer.

The Core Ultra 7 265 wins everywhere else. In Cinebench R23, the multi-core score of 42,216 versus 26,455 gives a 37.3 percent advantage. The single-core gap in R23 is 5,960 versus 3,734, also 37.3 percent. PassMark multi-thread shows 49,682 versus 31,124, a 37.4 percent lead. The largest single delta is in PassMark find prime numbers, where the Core Ultra 7 265 scores 418 against 159, a 62 percent advantage. Floating point math shows 172,776 versus 76,468, a 55.7 percent lead. Data encryption hits 40,456 versus 18,448, a 54.4 percent gap. Extended instructions deliver 41,478 versus 24,672, a 40.5 percent lead. Random string sorting goes 63,833 versus 35,798, a 43.9 percent margin. Data compression shows 522,983 versus 346,623, a 33.7 percent lead. Integer math is the narrowest PassMark win at 25.9 percent, with 134,773 versus 99,819. Physics shows 2,923 versus 2,493, a 14.7 percent lead. Single-thread PassMark gives 4,689 versus 4,219, a 10 percent margin.

Architecture Differences

The two processors come from different foundries and nodes. The Core 5 223PE uses Intel's 10 nm process and carries the Bartlett Lake codename. The Core Ultra 7 265 uses a 3 nm process from TSMC and carries the Arrow Lake-S codename, part of the Core Ultra Series 2. The Core Ultra 7 265 lists 17,800 million transistors on a 243 mm² die, while the Core 5 223PE does not report transistor count or die size in the database.

Core counts differ sharply. The Core 5 223PE has 8 cores and 16 threads. The Core Ultra 7 265 has 20 cores and 20 threads, meaning it does not use simultaneous multithreading. Base clocks are 2.90 GHz for the Core 5 and 2.40 GHz for the Core Ultra 7, but boost clocks are close: 5.20 GHz versus 5.30 GHz. Both are locked multipliers.

Cache hierarchies diverge. The Core 5 has 80 KB L1 per core, 2 MB L2 per core, and 24 MB shared L3. The Core Ultra 7 has 192 KB L1 per core, 3 MB L2 per core, and 30 MB shared L3. The Core Ultra 7 also supports DDR5 only, with dual-channel memory and 102.4 GB/s bandwidth. The Core 5 supports both DDR4 and DDR5, also dual-channel, with 89.6 GB/s bandwidth. ECC memory is supported on the Core 5 but not on the Core Ultra 7.

PCIe configurations differ. The Core 5 offers Gen 5 with 16 lanes (CPU only). The Core Ultra 7 offers Gen 5 with 20 lanes (CPU only). Integrated graphics also differ: UHD Graphics 730 on the Core 5, Arc Xe-LPG Graphics 32EU on the Core Ultra 7. Sockets are incompatible: Intel Socket 1700 for the Core 5, Intel Socket 1851 for the Core Ultra 7.

Head-to-Head Benchmarks

The largest win for the Core Ultra 7 265 appears in PassMark find prime numbers. A score of 418 versus 159 represents a 62 percent advantage. This is a strong indicator of raw integer and algorithmic throughput, where the higher core count and newer process node show clear separation.

Floating point math follows closely. The Core Ultra 7 265 scores 172,776 against 76,468, a 55.7 percent lead. Data encryption shows 40,456 versus 18,448, a 54.4 percent gap. Extended instructions deliver 41,478 versus 24,672, a 40.5 percent margin. These results cluster in the 50 to 60 percent range, suggesting the Core Ultra 7 265 has a decisive throughput advantage in compute-heavy PassMark subtests.

Random string sorting shows 63,833 versus 35,798, a 43.9 percent lead. Data compression shows 522,983 versus 346,623, a 33.7 percent margin. Integer math shows 134,773 versus 99,819, a 25.9 percent lead, the narrowest PassMark gap. Physics shows 2,923 versus 2,493, a 14.7 percent lead. PassMark single-thread shows 4,689 versus 4,219, a 10 percent lead.

Cinebench results tell a split story. In R15, the Core Ultra 7 265 wins multi-core 4,255 versus 2,666 and single-core 600 versus 376, both by 37.3 percent. In R23, it wins multi-core 42,216 versus 26,455 and single-core 5,960 versus 3,734, again by 37.3 percent. But in R20, the Core 5 223PE wins multi-core 11,111 versus 6,268 and single-core 1,568 versus 884, both by over 77 percent. This R20 anomaly is the only place where the Core 5 turns the tables, and it does so with a very large margin.
