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

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the Intel Core 5 223PE, which wins all 17 recorded head-to-head comparisons against the Intel Core i5-14400. The most striking result is in PassMark's find prime numbers test, where the Core 5 223PE scores 159 versus 80 for the i5-14400, a 98.8% advantage. That is the largest single delta in the entire comparison, indicating a substantial difference in integer-heavy computational workloads.

The Cinebench suite shows a consistent pattern. Across all six Cinebench tests (R15, R20, and R23, each in single-core and multi-core variants), the Core 5 223PE leads by exactly 24.1%. In Cinebench R23 multi-core, the Core 5 223PE posts 26455 points against 21315 for the i5-14400. The single-core R23 result tells a similar story: 3734 versus 3009. These consistent deltas suggest the performance gap is structural rather than workload-specific, likely stemming from the architectural and frequency differences detailed in the next section.

PassMark results reinforce the pattern with varying margins. In floating point math, the Core 5 223PE scores 76468 versus 61549, a 24.2% lead. Integer math shows a 21.7% advantage (99819 versus 82017). Extended instructions favor the Core 5 223PE by 24.5% (24672 versus 19816). The physics test delivers a 78.6% lead (2493 versus 1396), the second-largest margin in the dataset after the prime number test. Multithread performance is 24.1% higher (31124 versus 25080).

The smallest margins appear in data compression, encryption, and random string sorting. Data compression shows a 10% lead (346623 versus 314995), data encryption a 10.3% edge (18448 versus 16731), and random string sorting a 10.7% advantage (35798 versus 32346). These are still clear wins, but the reduced delta suggests that memory bandwidth or cache behavior narrows the gap in these tasks. Single-thread performance in PassMark shows a 12.8% lead (4219 versus 3741), a more modest advantage than the Cinebench single-core tests would imply.

Architecture Differences

The two processors share several fundamentals: both use Intel's 10 nm process node, both are built for Intel Socket 1700, and both support DDR4 and DDR5 memory in a dual-channel configuration. Both also feature UHD Graphics 730 integrated graphics, Gen 5 PCIe with 16 CPU lanes, and ECC memory support. The Core 5 223PE carries the Bartlett Lake codename, while the i5-14400 uses Raptor Lake-R and the Raptor Lake architecture. The i5-14400 is part of the Core 14th Gen series; the Core 5 223PE has no listed series designation.

Core configuration differs meaningfully. The i5-14400 has 10 cores and 16 threads, while the Core 5 223PE has 8 cores and 16 threads. The Core 5 223PE reaches thread parity through its 16 threads across 8 cores, implying a higher thread-per-core ratio. Clock speeds favor the Core 5 223PE: base clock of 2.90 GHz versus 2.50 GHz, and boost clock of 5.20 GHz versus 4.70 GHz. The Core 5 223PE therefore offers both a higher floor and a higher ceiling.

Cache layouts show a mixed picture. Both allocate 80 KB of L1 cache per core. The L2 cache is 2 MB per core on the Core 5 223PE versus 1.25 MB per core on the i5-14400. The shared L3 cache is 24 MB on the Core 5 223PE versus 20 MB on the i5-14400. The Core 5 223PE leads in both per-core L2 and shared L3 capacity, which helps explain its lead in cache-sensitive workloads. The i5-14400 has a listed die size of 215 mm², while the Core 5 223PE has no die size recorded.

Power envelopes are identical at 65 W TDP for both parts. Neither processor has an unlocked multiplier. The Core 5 223PE's part number is SA4QF, while the i5-14400 lists SRN3QSRN46. The Core 5 223PE has a launch MSRP of $232, and the i5-14400 has a launch MSRP of $221.

Where Each One Wins

The Core 5 223PE wins every recorded benchmark, so the analysis is about the size and nature of the margins rather than which processor takes specific categories. The largest wins are in prime number finding (98.8%) and physics (78.6%), both of which suggest workloads with heavy integer arithmetic or physics simulation logic benefit disproportionately from the Core 5 223PE's higher boost clock and larger cache configuration.

The Cinebench family shows a uniform 24.1% advantage, covering both single-core and multi-core rendering tasks. This consistency indicates a broad architectural efficiency gain that is not limited to a particular instruction type. Rendering, 3D modeling, and video encoding workloads that scale with Cinebench scores should see similar proportional improvements.

The more moderate wins in data compression (10%), encryption (10.3%), and random string sorting (10.7%) suggest that memory-bound or latency-sensitive tasks narrow the gap. The i5-14400's higher core count of 10 may help in workloads that benefit from additional physical cores, even though the Core 5 223PE still wins these tests. The single-thread PassMark result (12.8% lead) is the smallest single-thread margin, indicating that the Core 5 223PE's clock advantage does not translate equally to all single-threaded tasks.

The i5-14400's strongest relative performance appears in compression and sorting workloads, where the margin drops to roughly 10%. For users running heavily memory- or storage-oriented tasks, the i5-14400 remains competitive despite losing the absolute comparison. The Core 5 223PE's wins are largest in compute-heavy, cache-friendly workloads and smallest in data movement tasks.

The Verdict

The recorded data supports the Intel Core 5 223PE as the stronger performer in every measured category. Its 17-0 win record, combined with the uniform 24.1% Cinebench advantage and the extreme 98.8% lead in prime number finding, indicates a processor that delivers broadly higher throughput across rendering, math, physics, and general multithreaded workloads. The higher boost clock (5.20 GHz versus 4.70 GHz), larger L2 cache per core (2 MB versus 1.25 MB), and larger shared L3 cache (24 MB versus 20 MB) provide a plausible structural explanation for the results.

The i5-14400 retains relevance in specific scenarios. Its 10-core configuration gives it more physical cores, and its narrowest losses appear in data compression, encryption, and sorting tasks, where the margin shrinks to around 10%. The i5-14400's launch MSRP of $221 places it below the Core 5 223PE's launch MSRP of $232, though the benchmark data shows the higher-priced part delivering superior results across the board.

The Core 5 223PE sits at the 87th percentile of all CPUs in the database, while the i5-14400 sits at the 82nd percentile. The Core 5 223PE's average benchmark score is 40585, and its nearest rivals include the Intel Core 7 253PE (40557, 0.1% ahead) and the Intel Xeon 6357P (40630, 0.1% behind). The i5-14400's average score is 32115, with rivals such as the Intel Core i7-12800H (32121, 0% delta) and the Intel Core i9-11900 (32226, 0.3% behind). The 8470-point gap in average score between the two reviewed processors is substantial and consistent with the head-to-head results.

For workloads that mirror Cinebench rendering or PassMark math tests, the Core 5 223PE is the clear choice. For workloads dominated by data compression or sorting, the i5-14400 narrows the gap but still loses. The data does not identify any benchmark category where the i5-14400 wins. The Core 5 223PE is the stronger processor in this comparison, and the i5-14400's only advantages are its lower launch MSRP and higher physical core count.
