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

The Verdict

The recorded data presents an unambiguous outcome: the Intel Core 5 223PE wins all 17 head-to-head benchmark comparisons against the Intel Core i5-14400T. The Core 5 223PE delivers a 53.9% advantage in Cinebench R23 multi-core (26455 vs 17189) and a 53.9% lead in single-core (3734 vs 2426). The Core 5 223PE sits at the 87th percentile of all CPUs, while the i5-14400T sits at the 79th percentile. The Core i5-14400T's only redeeming characteristic is its lower 35W TDP compared to the Core 5 223PE's 65W TDP, which positions it for constrained thermal environments. However, for any workload where performance matters, the Core 5 223PE is the data-backed selection. The Core i5-14400T's nearest rivals include the Intel Core i9-9900K (0.3% higher average score) and AMD Ryzen 7 5700G (0.4% higher), indicating it competes with older-generation parts, while the Core 5 223PE's nearest rivals are the Intel Core 7 253PE (0.1% higher) and AMD Ryzen AI 5 PRO 435G (0.3% lower), placing it in a distinctly higher performance tier.

Where Each One Wins

The Core 5 223PE wins in every measured category, with no exceptions. The largest deltas appear in integer-heavy and physics workloads. The PassMark find prime numbers test shows a 117.8% advantage (159 vs 73), and PassMark physics shows a 100.4% lead (2493 vs 1244). These results indicate the Core 5 223PE handles computational density and iterative integer workloads with substantially greater efficiency. The smallest delta appears in PassMark single-thread performance, where the Core 5 223PE leads by 20.1% (4219 vs 3512), still a decisive margin but notably smaller than the multi-threaded gaps.

For the i5-14400T, the data provides no workload where it outperforms the Core 5 223PE. Its 35W TDP, however, is a meaningful differentiator for passive-cooled or low-power desktop builds, small-form-factor systems, or environments with strict thermal budgets. The i5-14400T also uses a 215 mm² die, while the Core 5 223PE's die size is not recorded, so physical footprint comparisons cannot be made. The i5-14400T's 10 cores and 16 threads match the Core 5 223PE's 16 threads, but the Core 5 223PE does so with 8 cores, indicating higher per-core throughput.

Architecture Differences

The Core 5 223PE uses the Bartlett Lake codename with a 10 nm process node, while the i5-14400T uses the Raptor Lake-R codename from the Raptor Lake architecture, also on a 10 nm node. Both processors use the Intel Socket 1700 and are manufactured by Intel. The Core 5 223PE has 8 cores and 16 threads, while the i5-14400T has 10 cores and 16 threads. The Core 5 223PE's base clock is 2.90 GHz with a boost clock of 5.20 GHz. The i5-14400T's base clock is 1.50 GHz with a boost clock of 4.50 GHz. The Core 5 223PE therefore has a substantially higher base clock (nearly double) and a 0.70 GHz higher boost ceiling.

Cache configurations differ notably. The Core 5 223PE has 2 MB of L2 cache per core and 24 MB of shared L3 cache. The i5-14400T has 1.25 MB of L2 cache per core and 20 MB of shared L3 cache. Both have 80 KB of L1 cache per core. The Core 5 223PE's larger L2 and L3 allocations contribute to its benchmark leads, particularly in memory-latency-sensitive workloads. Memory support is identical: both support DDR4 and DDR5 in dual-channel mode, and both support ECC memory. The Core 5 223PE records a memory bandwidth of 89.6 GB/s, while the i5-14400T's memory bandwidth is not recorded. Both use PCIe Gen 5 with 16 lanes from the CPU, and both integrate UHD Graphics 730. Neither processor has an unlocked multiplier. The Core 5 223PE was released in March 2026 with a launch MSRP of $232. The i5-14400T was released in January 2024 with a launch MSRP of $221.

Head-to-Head Benchmarks

The Cinebench suite shows consistent 53.9% to 54.1% leads for the Core 5 223PE. In Cinebench R15 multi-core, the Core 5 223PE scores 2666 versus 1732, a 53.9% delta. Single-core R15 shows 376 versus 244, a 54.1% delta. Cinebench R20 multi-core records 11111 versus 7219 (53.9%), and single-core records 1568 versus 1018 (54%). Cinebench R23 multi-core scores 26455 versus 17189 (53.9%), with single-core at 3734 versus 2426 (53.9%). These consistent margins across Cinebench versions indicate that the Core 5 223PE's architectural efficiency translates uniformly across rendering workloads regardless of scene complexity or scaling methodology.

PassMark integer math shows the Core 5 223PE at 99819 versus 65667, a 52% lead. Floating point math shows 76468 versus 49139, a 55.6% lead. Extended instructions (SIMD-heavy workloads) show a 69.4% advantage (24672 versus 14562). The largest PassMark gap appears in find prime numbers: 159 versus 73, a 117.8% delta. This test is highly sensitive to single-thread integer throughput and cache behavior, and the Core 5 223PE's higher boost clock and larger L2 cache per core explain the outsized margin. PassMark physics shows 2493 versus 1244, a 100.4% delta, another workload that benefits from per-core resources and clock speed.

Data compression favors the Core 5 223PE by 47.1% (346623 versus 235636). Data encryption shows a 39.3% lead (18448 versus 13244). Random string sorting shows a 42.2% lead (35798 versus 25181). PassMark multi-thread shows 31124 versus 20223, a 53.9% delta, matching the Cinebench multi-core margins. PassMark single-thread shows 4219 versus 3512, a 20.1% delta. This smaller single-thread gap suggests that the i5-14400T's architectural efficiency per clock is closer to the Core 5 223PE than the multi-threaded results imply, but the Core 5 223PE's higher clocks and larger caches still secure a decisive win.

The average benchmark score for the Core 5 223PE is 40585, versus 27166 for the i5-14400T. The Core 5 223PE's nearest rival, the Intel Core 7 253PE, scores 40557 (0.1% higher), and the Intel Xeon 6357P scores 40630 (0.1% lower). The i5-14400T's nearest rival, the Intel Core i9-9900K, scores 27097 (0.3% higher), and the AMD Ryzen 7 5700G scores 27051 (0.4% higher). These rival placements confirm that the Core 5 223PE operates in a performance class roughly 50% above the i5-14400T, and that the i5-14400T aligns with processors from previous generations rather than current high-performance desktop parts.
