Extended instructions and prime number finding also favor AMD, with 13% and 11.3% leads respectively. Single-thread PassMark performance goes to AMD by a narrower 4.3% margin (3901 vs 3741).

The Intel Core i5-14400 counters with decisive wins in the Cinebench suite. In Cinebench R23 multi-core, Intel scores 21315 against AMD's 18316, a 14.1% lead. The single-core gap is even larger: Intel leads by 32.3% in Cinebench R23 single-core (3009 vs 2038) and by 29% in Cinebench R15 single-core (303 vs 215). Intel also wins PassMark floating-point math (61549 vs 54447, 11.5% ahead) and PassMark data encryption (16731 vs 16247, 2.9% ahead). PassMark data compression is nearly a tie, with AMD edging out Intel by just 0.3% (315906 vs 314995).

Looking at the aggregate scores, the AMD Ryzen AI 7 450 holds a 39485 average benchmark score against Intel's 32115. That places AMD at the 87th percentile of all CPUs in the database, while the Core i5-14400 sits at the 82nd percentile. The AMD chip's nearest rivals in the database include the AMD Ryzen 7 9800X3D (0.7% higher average score) and the AMD Ryzen 7 PRO 8840HS (0.3% lower). The Intel chip's closest competitor is the Intel Core i7-12800H, which matches its average score exactly, with the Core i5-14450HX just 0.2% behind.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 450 uses the Zen 5 architecture under the Gorgon Point codename, built on TSMC's 4 nm process with a 195 mm² die. It belongs to the Ryzen AI 400 generation, which mixes Zen 5 and Zen 5c cores. The Intel Core i5-14400 uses Raptor Lake architecture under the Raptor Lake-R codename, built on Intel's 10 nm process with a 215 mm² die. It is part of the Core 14th Gen family, specifically the Raptor Lake Refresh generation.

Core counts differ significantly. The AMD chip has 8 cores and 16 threads, while the Intel chip has 10 cores and 16 threads. Both offer the same thread count, but Intel gets there with more physical cores. Cache layouts also diverge. Both have 80 KB of L1 cache per core. AMD provides 1 MB of L2 per core and 8 MB of L3 cache. Intel provides 1.25 MB of L2 per core and 20 MB of shared L3 cache. That larger L3 pool on Intel likely contributes to its strong Cinebench results.

Clock speeds tell a different story. The AMD Ryzen AI 7 450 has a 2.00 GHz base clock and a 5.10 GHz boost clock. The Intel Core i5-14400 has a 2.50 GHz base clock and a 4.70 GHz boost clock. Intel starts higher at base, but AMD boosts higher at peak. The TDP figures are far apart: AMD is rated at 28 W, Intel at 65 W. That makes the AMD chip a mobile-oriented part, while Intel targets desktop systems. The socket types confirm this: AMD uses Socket FP8, Intel uses Socket 1700.

Memory support differs as well. AMD supports DDR5 and LPDDR5X with dual-channel bus and 89.6 GB/s of bandwidth. Intel supports DDR4 and DDR5 with dual-channel bus; no bandwidth figure is recorded in the database for Intel. Both support ECC memory. PCIe capabilities also diverge: AMD provides Gen 4 with 16 lanes, Intel provides Gen 5 with 16 lanes. Integrated graphics differ, with AMD using Radeon 860M and Intel using UHD Graphics 730. The AMD chip has a 2026 release date, while Intel's dates to 2024. The Intel part carries a launch MSRP of $221; no launch MSRP is recorded for AMD.

The Verdict

The benchmark data describes two processors with opposite strengths. The AMD Ryzen AI 7 450 dominates in multi-threaded integer workloads, physics simulation, and overall PassMark scoring. It wins 10 of 15 head-to-head tests and carries the higher average benchmark score, 39485 vs 32115, which is a 23% advantage in aggregate. Its 87th percentile ranking versus Intel's 82nd also reflects that overall lead.

The Intel Core i5-14400 is the stronger choice for single-core-heavy and floating-point workloads. Its Cinebench R23 single-core score of 3009 beats AMD's 2038 by a massive 32.3%. Its Cinebench R23 multi-core score of 21315 beats AMD's 18316 by 14.1%. Those are substantial margins, not statistical noise. The data suggests that software that scales well with the Intel core layout and benefits from the larger 20 MB L3 cache will favor Intel.

The power envelope matters. AMD's 28 W TDP against Intel's 65 W TDP means the Ryzen AI 7 450 delivers comparable or better multi-threaded PassMark results while using less than half the rated power. The Cinebench R23 multi-core result goes the other way, with Intel ahead by 14.1%, so the power efficiency advantage is workload-dependent. The Intel chip does have a higher base clock and more physical cores, which helps in certain throughput scenarios.

For a desktop builder prioritizing raw single-core speed and floating-point throughput, the data points to the Intel Core i5-14400. For a mobile system designer or anyone prioritizing multi-threaded integer work, physics, and overall aggregate performance at lower power, the AMD Ryzen AI 7 450 has the stronger record.

Where Each One Wins

The AMD Ryzen AI 7 450 wins in integer math, multi-threaded PassMark, physics simulation, prime number finding, random string sorting, extended instructions, and data compression by a 0.3% margin. It also wins PassMark single-thread tests and Cinebench R15 multi-core. These are workloads that respond well to the Zen 5 architecture's instruction throughput and the 5.10 GHz boost clock. The 28 W TDP makes it suitable for mobile platforms where power efficiency matters. Its 89.6 GB/s memory bandwidth supports memory-intensive tasks.

The Intel Core i5-14400 wins in Cinebench R23 multi-core and single-core, Cinebench R15 single-core, floating-point math, and data encryption. The 20 MB shared L3 cache and 10 physical cores give it an edge in workloads that benefit from large cache residency and more execution units. The 65 W TDP is a desktop-class figure, and the Gen 5 PCIe support provides higher I/O bandwidth for expansion. The 2.50 GHz base clock helps sustain throughput in all-core scenarios.

For compression, encryption, and floating-point work, the data shows Intel holding narrow leads in encryption and floating-point but losing compression by a hair. For integer-heavy, physics-based, and general multi-threaded workloads, AMD demonstrates consistent superiority across the PassMark suite. The Cinebench results are the outlier: Intel wins both R23 tests convincingly, suggesting that rendering workloads specifically favor Intel's core configuration. The overall win count, 10 for AMD and 5 for Intel, aligns with the aggregate score advantage and the percentile ranking difference.
