Intel Core 5 223PQE vs Intel Core i5-14400 Comparison

The Verdict

The database contains no benchmark scores for the Intel Core 5 223PQE, while the Intel Core i5-14400 has a full suite of recorded measurements. This makes a direct performance comparison impossible based on measured data. The Core i5-14400 holds an average benchmark score of 32115 and sits at the 82nd percentile of all CPUs. The Core 5 223PQE has no recorded average score and sits at the 50th percentile, a placeholder position rather than a measured result.

For users selecting between these two processors, the data supports different choices depending on priorities. The Intel Core i5-14400 is the only one of the two with verified benchmark results, including a Cinebench R23 multi-core score of 21315 and a single-core score of 3009. The Intel Core 5 223PQE offers a higher boost clock of 5.50 GHz versus 4.70 GHz, a larger shared L3 cache of 24 MB versus 20 MB, and a higher base clock of 4.00 GHz versus 2.50 GHz. These specifications suggest the Core 5 223PQE may have an advantage in single-threaded responsiveness, but without measured scores, that remains speculative. The Core i5-14400 is the safer choice based on available evidence, as it has proven results across multiple test suites. The Core 5 223PQE is the choice for those who prioritize the newer release date of 2026-03-08 and the higher clock ceilings listed in its specifications.

Architecture Differences

The Intel Core 5 223PQE is built on the Bartlett Lake codename, while the Intel Core i5-14400 uses the Raptor Lake architecture with the Raptor Lake-R codename. Both are manufactured on a 10 nm process node at Intel. The Core 5 223PQE has 8 cores and 16 threads, whereas the Core i5-14400 has 10 cores and 16 threads. This means the Core i5-14400 relies on a mix of core types to reach its thread count, while the Core 5 223PQE achieves 16 threads with fewer physical cores.

Cache structures differ notably between the two. The Core 5 223PQE provides 80 KB of L1 cache per core and 2 MB of L2 cache per core, with 24 MB of shared L3 cache. The Core i5-14400 also provides 80 KB of L1 cache per core but only 1.25 MB of L2 cache per core, with 20 MB of shared L3 cache. The Core 5 223PQE therefore has a larger per-core L2 allocation and a larger total L3 pool.

The integrated graphics differ as well. The Core 5 223PQE includes UHD Graphics 770, while the Core i5-14400 includes UHD Graphics 730. Both processors support DDR4 and DDR5 memory with a dual-channel memory bus. The Core 5 223PQE lists a memory bandwidth of 89.6 GB/s, while the Core i5-14400 has no recorded memory bandwidth figure in the database. Both support ECC memory and use Gen 5 PCIe with 16 lanes from the CPU.

The release timeline separates these parts clearly. The Core i5-14400 was released on 2024-01-07, and the Core 5 223PQE followed on 2026-03-08. The Core 5 223PQE has the part number SA4QC, while the Core i5-14400 has the part numbers SRN3Q and SRN46. Both are desktop processors with active production status and neither has an unlocked multiplier.

Specification Differences

The base clock differs substantially: the Core 5 223PQE runs at 4.00 GHz, while the Core i5-14400 runs at 2.50 GHz. The boost clock also favors the Core 5 223PQE at 5.50 GHz versus 4.70 GHz. TDP is another clear split, with the Core 5 223PQE rated at 125 and the Core i5-14400 at 65.

Core counts differ: 8 cores for the Core 5 223PQE against 10 cores for the Core i5-14400. Thread counts are equal at 16. L2 cache per core is 2 MB for the Core 5 223PQE and 1.25 MB for the Core i5-14400. L3 cache is 24 MB shared for the Core 5 223PQE and 20 MB shared for the Core i5-14400.

The die size field is only recorded for the Core i5-14400 at 215 mm². The Core 5 223PQE has no die size listed. Integrated graphics differ, with UHD Graphics 770 on the Core 5 223PQE and UHD Graphics 730 on the Core i5-14400. Memory bandwidth is listed for the Core 5 223PQE at 89.6 GB/s, but no figure exists for the Core i5-14400.

Both processors share the same socket, process node, foundry, memory support, memory bus, ECC capability, PCIe configuration, market segment, and production status. The launch MSRP for the Core 5 223PQE is $319, and the launch MSRP for the Core i5-14400 is $221.

Head-to-Head Benchmarks

The database has no head-to-head benchmark entries between these two processors, and the Core 5 223PQE has no individual benchmark scores recorded. All measured performance data belongs to the Core i5-14400. That processor delivers a Cinebench R23 multi-core score of 21315 and a single-core score of 3009. In Cinebench R20, it records 8952 multi-core and 1263 single-core. In Cinebench R15, the scores are 2148 multi-core and 303 single-core.

Geekbench results for the Core i5-14400 show a multi-core score of 9807 and a single-core score of 1905. Passmark tests cover a range of workloads. The multi-thread score is 25080, and the single-thread score is 3741. Integer math reaches 82017, floating point math reaches 61549, and extended instructions reach 19816. Data compression scores 314995, data encryption scores 16731, and random string sorting scores 32346. The physics test records 1396, and the find prime numbers test records 80.

The Core i5-14400 ranks at the 82nd percentile of all CPUs, with an average benchmark score of 32115. Its nearest rivals in the database are the Intel Core i7-12800H with an average score of 32121 and a delta of 0 percent, the Intel Core i7-13705H with 32076 and a delta of 0.1 percent, the Intel Core i5-14450HX with 32040 and a delta of 0.2 percent, and the Intel Core i9-11900 with 32226 and a delta of -0.3 percent. These narrow deltas place the Core i5-14400 in a tightly competitive band where the differences between adjacent processors are within a fraction of a percent.

For the Core 5 223PQE, the absence of recorded benchmarks means no wins can be attributed to it in measured performance. Its specification sheet indicates higher clocks and more cache, but the database does not yet contain the results to confirm how those specifications translate into application performance. The Core i5-14400, by contrast, has verified results across multiple generations of Cinebench, Geekbench, and Passmark tests, giving it a clear evidentiary advantage in any comparison based on recorded data.
