Intel Core i5-14400T vs Intel Core Ultra 5 225T Comparison

Head-to-Head Benchmarks

The recorded data shows a clear overall winner in the Intel Core Ultra 5 225T, which takes 15 of the 17 head-to-head benchmark comparisons. The Intel Core i5-14400T manages only 2 wins, both in PassMark workloads. Across the full Cinebench suite, the Core Ultra 5 225T holds a consistent 21.8% lead in every test. In Cinebench R23 multicore, the Ultra 5 scores 21971 against the i5-14400T's 17189. The single-core R23 result follows the same pattern: 3101 versus 2426, again a 21.8% gap.

The Cinebench R15, R20, and R23 tests all report the identical 21.8% delta, which indicates the Core Ultra 5 225T scales its advantage uniformly across rendering workloads regardless of the specific benchmark version. The multicore and single-core deltas match exactly, so the Ultra 5's advantage is not limited to parallel tasks. It wins by the same margin in both single-threaded and multi-threaded rendering.

The PassMark suite reveals a more varied picture. The Core Ultra 5 225T wins data encryption scoring 18289 against 13244, a 27.6% margin. Extended instructions show a similar 27.5% edge with scores of 20083 versus 14562. The largest gap in the entire comparison appears in find prime numbers, where the Ultra 5 scores 284 against the i5-14400T's 73, a 74.3% difference. Floating point math also favors the Ultra 5 heavily: 82751 versus 49139, a 40.6% lead. Physics testing shows 2053 versus 1244, a 39.4% margin.

The i5-14400T secures its two wins in integer math and data compression. In integer math, it scores 65667 against 59543, a 10.3% advantage. Data compression is a narrow 0.7% win with 235636 versus 233998. These two results demonstrate that the older chip retains some strengths in specific integer-heavy and compression workloads, despite losing the overall average benchmark comparison.

The average benchmark scores reflect this overall split. The Core Ultra 5 225T averages 30468 and sits in the 82nd percentile of all CPUs. The i5-14400T averages 27166 and sits in the 79th percentile. The nearest rivals for the Ultra 5 include the Intel Core i9-11980HK with an average score of 30422 and a 0.2% delta, the AMD Ryzen 5 7640HS at 30390 with a 0.3% delta, and the AMD Ryzen 7 7736U at 30364 with a 0.3% delta. The i5-14400T's closest competitors are the Intel Core i9-9900K at 27097 with a 0.3% delta and the AMD Ryzen 7 5700G at 27051 with a 0.4% delta.

Where Each One Wins

The Core Ultra 5 225T dominates rendering and compute-heavy tasks. All six Cinebench tests go to the Ultra 5, making it the stronger choice for CPU-bound rendering work. The 21.8% margin across every Cinebench variant means the advantage is structural rather than workload-specific. The PassMark physics and floating point results reinforce this, with 39.4% and 40.6% leads respectively. Data encryption and extended instructions also favor the Ultra 5 by more than 27%, so cryptographic workloads and SIMD-heavy code run noticeably faster on the newer chip.

The i5-14400T wins in integer math by 10.3%, which points to a specific strength in integer-heavy code paths. Its data compression result is nearly identical to the Ultra 5, only 0.7% higher, so that win is marginal in practical terms. The i5-14400T also offers 16 threads against the Ultra 5's 10 threads, which explains its competitiveness in the multithreaded PassMark test where it loses by 20.3% rather than the larger margins seen elsewhere. The multithread score of 20223 versus 25358 shows the i5-14400T's extra threads help narrow the gap, but the Ultra 5's higher per-core efficiency still carries the day.

For single-threaded performance, the Ultra 5 leads by 19.2% in PassMark single thread with 4348 against 3512. The Cinebench R23 single-core test shows a similar 21.8% gap. Users running lightly threaded applications will see a substantial advantage from the Ultra 5. The find prime numbers result, a 74.3% gap, is the most extreme single-workload difference and indicates the Ultra 5's architecture handles that particular algorithm far more efficiently.

Architecture Differences

The two processors come from different Intel architectures. The i5-14400T uses Raptor Lake, specifically the Raptor Lake-R codename, part of the Core 14th Gen series.

The Verdict

The benchmark data indicates the Intel Core Ultra 5 225T is the stronger processor in nearly every measured workload. It wins 15 of 17 head-to-head comparisons, holds a 21.8% lead across all Cinebench tests, and posts a higher average benchmark score of 30468 against 27166. Its 82nd percentile ranking versus the i5-14400T's 79th percentile confirms its higher standing among all CPUs. The Ultra 5 also delivers more than double the performance in find prime numbers and leads by roughly 40% in floating point math and physics, making it the clear choice for compute-intensive applications.

The i5-14400T remains relevant only in specific niches. Its 10.3% integer math win and 0.7% data compression win show that certain integer-heavy workloads still favor the older architecture. Its 16 threads provide more parallel capability than the Ultra 5's 10 threads, yet the multithreaded PassMark score still goes to the Ultra 5 by 20.3%, which shows the thread count advantage does not translate into a win. The i5-14400T also has a lower 35 watt TDP against 65 watts for the Ultra 5, and it supports both DDR4 and DDR5 memory, which gives it broader platform compatibility. The Ultra 5's higher base clock, higher boost clock, larger per-core cache, newer 3 nm process, and 102.4 GB/s memory bandwidth all contribute to its dominant benchmark performance. Users prioritizing raw performance should select the Core Ultra 5 225T, while those constrained by power limits or existing DDR4 infrastructure may find the i5-14400T suitable despite its lower scores.
