Architecture Differences

The two processors come from different Intel generations and manufacturing approaches. The i5-14400 uses Raptor Lake architecture, specifically the Raptor Lake-R refresh, built on Intel's 10 nm process with a die size of 215 mm². The Core Ultra 5 225T uses Arrow Lake architecture, specifically Arrow Lake-S, fabricated by TSMC on a 3 nm process with a die size of 243 mm² and a transistor count of 17,800 million.

Both chips feature 10 cores, but threading differs significantly. The i5-14400 supports 16 threads, while the Core Ultra 5 225T supports 10 threads. This means the i5-14400 relies on simultaneous multithreading to reach its thread count, while the Ultra 5 225T operates with a one-to-one core-to-thread ratio.

Cache layouts diverge substantially. The i5-14400 uses 80 KB of L1 cache per core and 1.25 MB of L2 cache per core, with 20 MB of shared L3 cache. The Core Ultra 5 225T uses 192 KB of L1 cache per core and 3 MB of L2 cache per core, also with 20 MB of shared L3 cache. The larger per-core cache allocations on the Ultra 5 225T align with its single-thread performance advantage.

Clock speeds show a modest difference. Both processors have a base clock of 2.50 GHz, but the boost clock reaches 4.70 GHz on the i5-14400 and 4.90 GHz on the Core Ultra 5 225T. Both have a 65 W TDP.

Platform support differs in several ways. The i5-14400 uses Intel Socket 1700, while the Ultra 5 225T uses Intel Socket 1851. Memory support also diverges: the i5-14400 supports both DDR4 and DDR5, while the Ultra 5 225T supports DDR5 only. The Ultra 5 225T lists a memory bandwidth of 102.4 GB/s, a figure not recorded for the i5-14400. ECC memory is supported on the i5-14400 but not on the Ultra 5 225T. PCIe lanes differ as well, with the i5-14400 offering Gen 5 with 16 lanes (CPU only) and the Ultra 5 225T offering Gen 5 with 20 lanes (CPU only).

Integrated graphics also differ. The i5-14400 includes UHD Graphics 730, while the Ultra 5 225T includes Arc Xe-LPG Graphics 16EU. Neither processor has an unlocked multiplier.

Where Each One Wins

The data indicates that the i5-14400 wins in workloads that rely on integer processing and data manipulation. Its 37.7% lead in integer math and 34.6% lead in data compression are the largest margins in either direction. Random string sorting, a task that exercises memory access and sorting algorithms, also favors the i5-14400 by 12.4%. These results suggest the i5-14400 has an edge in general productivity tasks, database-style operations, and compression workloads.

The Core Ultra 5 225T wins across rendering, physics simulation, and floating point workloads. Its Cinebench multicore and singlecore leads, while modest at around 3%, cover the full rendering benchmark suite. The 71.8% advantage in prime number finding and the 32% lead in physics indicate strong performance in mathematical and simulation workloads. Floating point math shows a 25.6% advantage, reinforcing the pattern that the Ultra 5 225T handles numerical computation more efficiently. Single-thread performance is also stronger, with a 14% lead in Passmark's single-thread test.

The multithread results are close. The Ultra 5 225T leads by 1.1% in Passmark multithread, despite having 10 threads versus 16 on the i5-14400. This indicates the Ultra 5 225T compensates for fewer threads with higher per-thread efficiency. The i5-14400's thread advantage does not translate into a win in the aggregate multithread test.

The Verdict

The data supports different choices depending on workload priorities. The Intel Core Ultra 5 225T is the stronger option for single-threaded performance, rendering workloads, physics simulation, and floating point math. Its wins in every Cinebench test, a 14% lead in Passmark single-thread, and substantial margins in prime number finding and physics make it the better fit for applications that depend on per-core efficiency and numerical computation.

The Intel Core i5-14400 is the better choice for integer-heavy and data-processing workloads. Its 37.7% lead in integer math, 34.6% lead in data compression, and 12.4% lead in random string sorting indicate an advantage in compression tools, data manipulation, and similar tasks. The higher thread count of 16 versus 10 does not produce a multithread win in the recorded tests, as the Ultra 5 225T edges ahead by 1.1% in Passmark multithread, but the i5-14400's average benchmark score of 32115 remains higher than the Ultra 5 225T's 30468.
