Intel Core 5 223PQE vs Intel Core Ultra 5 245K Comparison

Head-to-Head Benchmarks

The database records benchmark results only for the Intel Core Ultra 5 245K. The Intel Core 5 223PQE has no recorded benchmark scores, average score, or percentile ranking in the database. Consequently, no head-to-head comparisons can be derived from measured data. The Core Ultra 5 245K posts an average benchmark score of 54053, which places it in the 91st percentile among all CPUs tracked by the database. Its nearest rival, the Intel Xeon 6505P, scores 53701, a delta of 0.7 percent. The Intel Core i7-14700F trails at 53620, a 0.8 percent gap, and the Intel Xeon Phi 7290 follows at 53469, a 1.1 percent gap. The AMD Ryzen 9 9900X3D leads the Core Ultra 5 245K by 1.3 percent with a score of 54762. These figures indicate that the Core Ultra 5 245K sits in a tightly contested performance band, with all four nearest rivals within roughly 1.3 percent of its average score.

Within specific tests, the Core Ultra 5 245K shows its strongest results in Cinebench R23 multicore, where it records 25066 points. In Cinebench R20 multicore, it scores 15368, and in Cinebench R15 multicore, it scores 3850. Single-core results are 2132 in Cinebench R23, 2169 in Cinebench R20, and 322 in Cinebench R15. PassMark tests show a multithread score of 43047, a single-thread score of 4714, floating point math at 130678, integer math at 98524, extended instructions at 37617, data compression at 458817, data encryption at 33286, find prime numbers at 414, random string sorting at 55098, and physics at 3081. Since the Core 5 223PQE has no benchmark entries, every comparative statement in this analysis relies solely on the Core Ultra 5 245K's recorded data and its nearest rival deltas.

The absence of Core 5 223PQE benchmark data means the database cannot confirm any win for either processor. The wins counter shows 0 for both items. The correct interpretation is that the Core Ultra 5 245K is fully characterized, while the Core 5 223PQE remains unmeasured. Any claim of superiority would require fabricated data, which the database does not contain.

Where Each One Wins

The Core Ultra 5 245K wins in every measurable category because it is the only one of the two with recorded scores. Its 91st percentile ranking indicates strong overall performance relative to the full CPU database. The nearest rival data shows the Core Ultra 5 245K ahead of the Intel Xeon 6505P, the Intel Core i7-14700F, and the Intel Xeon Phi 7290, while trailing the AMD Ryzen 9 9900X3D by a small margin. In multithreaded workloads, the Cinebench R23 multicore score of 25066 and the PassMark multithread score of 43047 suggest solid parallel throughput. In single-threaded tasks, the Cinebench R23 single-core score of 2132 and the PassMark single-thread score of 4714 indicate competitive per-core performance. Specialized PassMark tests show high data compression throughput at 458817 and floating point math at 130678, while encryption at 33286 and extended instructions at 37617 are comparatively lower but still recorded.

For the Core 5 223PQE, no wins can be assigned. The database lists its percentile as 50, but without an average score or any benchmark entries, that percentile cannot be verified against measured data. The processor supports DDR4 and DDR5 memory, includes ECC memory support, and features UHD Graphics 770, but none of these attributes translate into a benchmark win without test scores.

Architecture Differences

The two processors come from different architectural lineages. The Core 5 223PQE uses the Bartlett Lake codename with a 10 nm process node fabricated by Intel. The Core Ultra 5 245K uses the Arrow Lake architecture with the Arrow Lake-S codename, a 3 nm process node fabricated by TSMC, and belongs to the Core Ultra Series 2 family. The Core Ultra 5 245K has 17,800 million transistors on a 243 mm² die. The Core 5 223PQE has no transistor or die size data recorded.

Cache hierarchies differ substantially. The Core 5 223PQE has 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 245K has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. The larger per-core L1 and L2 allocations on the Core Ultra 5 245K reflect its newer design. Both share the same total L3 capacity of 24 MB.

The Core Ultra 5 245K uses 14 cores and 14 threads, indicating a design without hyperthreading on its efficiency cores or a hybrid arrangement that does not double thread count. The Core 5 223PQE uses 8 cores and 16 threads, showing traditional hyperthreading. The Core Ultra 5 245K has a higher base clock of 4.20 GHz versus 4.00 GHz on the Core 5 223PQE, but the Core 5 223PQE has a higher boost clock of 5.50 GHz versus 5.20 GHz on the Core Ultra 5 245K.

Memory support diverges. The Core 5 223PQE supports both DDR4 and DDR5, while the Core Ultra 5 245K supports DDR5 only. Memory bandwidth is 89.6 GB/s for the Core 5 223PQE and 102.4 GB/s for the Core Ultra 5 245K. Both use dual-channel memory buses and both support ECC memory.

PCIe connectivity differs. The Core 5 223PQE provides Gen 5 with 16 lanes from the CPU. The Core Ultra 5 245K provides Gen 5 with 20 lanes from the CPU. Integrated graphics also differ: the Core 5 223PQE uses UHD Graphics 770, while the Core Ultra 5 245K uses Arc Xe-LPG Graphics 64EU.

The Core 5 223PQE uses Intel Socket 1700, while the Core Ultra 5 245K uses Intel Socket 1851. The Core Ultra 5 245K has an unlocked multiplier, while the Core 5 223PQE does not. The Core 5 223PQE was released on 2026-03-08, and the Core Ultra 5 245K was released on 2024-10-23. Both have a launch MSRP of $319.

The Verdict

The data in the database supports only one definitive choice: the Intel Core Ultra 5 245K. It has a recorded average benchmark score of 54053, a 91st percentile ranking, and 17 benchmark entries across Cinebench and PassMark tests. The Intel Core 5 223PQE has no benchmark scores, an average score of 0, and a 50th percentile that is not backed by any measured test. Any user selecting a processor based on recorded performance data must choose the Core Ultra 5 245K, because it is the only option with verifiable results.

The Core Ultra 5 245K also offers architectural advantages: a 3 nm process node from TSMC, 14 cores, larger per-core L1 and L2 caches, higher memory bandwidth at 102.4 GB/s, 20 PCIe Gen 5 lanes, and an unlocked multiplier. The Core 5 223PQE counters with a higher boost clock of 5.50 GHz, DDR4 and DDR5 support, 16 threads from 8 cores, and a lower memory bandwidth of 89.6 GB/s. These specification differences matter for specific workloads, but without benchmark scores for the Core 5 223PQE, the database cannot quantify their impact.

The nearest rival data for the Core Ultra 5 245K shows it in a close pack with the AMD Ryzen 9 9900X3D, Intel Xeon 6505P, Intel Core i7-14700F, and Intel Xeon Phi 7290. The 91st percentile placement indicates that it outperforms most CPUs in the database, while the small deltas to its nearest rivals suggest that the top of the field is tightly grouped. For the Core 5 223PQE, the absence of data means no performance assessment is possible. The database records its production status as Active and its release date as 2026-03-08, but active production does not substitute for measured scores.

A methodical reading of the database yields one clear outcome. The Intel Core Ultra 5 245K is the only processor of the two with performance data, and that data places it in the 91st percentile with a 54053 average score. The Intel Core 5 223PQE remains an unmeasured product in the database, and no benchmark evidence exists to support selecting it over the Core Ultra 5 245K. Users who require DDR4 memory support or a higher boost clock may note those specifications, but the recorded performance data points exclusively to the Core Ultra 5 245K.
