AMD Ryzen AI Embedded P164i vs Intel Core i5-14400 Comparison

The AMD Ryzen AI Embedded P164i and Intel Core i5-14400 occupy different corners of the processor market, but the data reveals a clear performance hierarchy. The Intel Core i5-14400 holds a substantial lead in multi-threaded workloads, while the AMD part counters with a higher top clock speed and a more efficient mobile design. The benchmark database shows the i5-14400 achieving an average benchmark score of 32,115, placing it in the 82nd percentile of all CPUs, while the P164i sits at the 50th percentile. The recorded data indicates a decisive performance gap in favor of the desktop Intel processor.

Head-to-Head Benchmarks

The Intel Core i5-14400 dominates the multi-core tests. In Cinebench R23, the i5-14400 scores 21,315 points, a figure that dwarfs the P164i's result. The gap extends across the entire Cinebench suite; the i5-14400 posts 8,952 in Cinebench R20 and 2,148 in Cinebench R15. Geekbench multi-core results confirm this trend, with the Intel chip scoring 9,807. The PassMark multi-thread test reinforces the narrative, showing the i5-14400 at 25,080, with integer math at 82,017 and floating-point math at 61,549. These scores indicate that the Intel part delivers significantly more sustained throughput for heavily threaded applications.

The single-core results tell a tighter story. In Cinebench R23 single-core, the i5-14400 scores 3,009, while the P164i's boost clock of 5.00 GHz suggests a competitive showing, though the database lacks a direct score for the AMD chip. The i5-14400's PassMark single-thread score of 3,741 and Cinebench R20 single-core score of 1,263 provide reference points. The Intel processor's 4.70 GHz boost clock trails the AMD part's 5.00 GHz, but the database shows the i5-14400 still delivering strong single-threaded performance.

Specialized workloads highlight the Intel chip's versatility. PassMark data encryption shows the i5-14400 at 16,731, extended instructions at 19,816, and data compression at 314,995. Random string sorting reaches 32,346, and physics simulation hits 1,396. Prime number finding scores 80. These figures demonstrate consistent performance across diverse task types, from memory-intensive sorting to cryptographic operations. The nearest rivals to the i5-14400, listed as the Intel Core i7-12800H with an average score of 32,121 and the Intel Core i7-13705H at 32,076, sit within a 0.1 percent delta, indicating the i5-14400 is closely matched with those mobile processors, despite its desktop positioning.

Where Each One Wins

The Intel Core i5-14400 wins decisively in multi-core throughput. The 10 cores, 16 threads, and 20 MB of shared L3 cache provide a clear advantage for rendering, compilation, and other parallel workloads. The Cinebench R23 multi-core score of 21,315 and the PassMark multi-thread figure of 25,080 position it as a capable desktop workhorse. The data shows no benchmark category where the P164i out-scores the i5-14400, as the wins column for the AMD part remains at zero in the head-to-head comparison.

The AMD Ryzen AI Embedded P164i wins on efficiency and platform integration. Its 28 W TDP is less than half the Intel chip's 65 W TDP, making it suited for compact or thermally constrained systems. The AMD part uses the FP8 socket, targets the mobile segment, and integrates Radeon 880M graphics, which delivers a more capable integrated GPU than the UHD Graphics 730 found on the i5-14400. The P164i also supports LPDDR5X memory, which can reduce power consumption in portable designs. Its 5.00 GHz boost clock is the highest of the two, giving it a theoretical edge in lightly threaded tasks, though the database lacks direct scores to confirm this advantage.

For desktop builds where power draw is less critical, the i5-14400 is the stronger choice based on recorded benchmarks. For embedded or mobile applications requiring lower energy use and a smaller footprint, the P164i's specifications align better, even without benchmark scores to quantify its performance ceiling.

Architecture Differences

The two processors come from different manufacturing and design philosophies. The AMD Ryzen AI Embedded P164i uses a 4 nm process node from TSMC, while the Intel Core i5-14400 uses a 10 nm node from Intel's own fabs. The smaller process node gives the AMD chip a potential efficiency advantage, reflected in its lower TDP. The AMD part belongs to the Gorgon Point codename and the Ryzen AI Embedded generation, which pairs Zen 5 and Zen 5c cores. The Intel chip is part of the Raptor Lake Refresh generation, built on the Raptor Lake architecture.

Core configurations differ significantly. The P164i has 8 cores and 16 threads, while the i5-14400 has 10 cores and 16 threads. Both support simultaneous multithreading, but the Intel chip's two additional cores explain its multi-core benchmark dominance. Cache hierarchies also diverge. The P164i has 80 KB of L1 cache per core, 1 MB of L2 per core, and 8 MB of L3. The i5-14400 has 80 KB of L1 per core, 1.25 MB of L2 per core, and a larger 20 MB of shared L3. The Intel part's 20 MB L3 cache provides more shared storage for frequently accessed data, which benefits multi-threaded workloads.

Memory support differs as well. The P164i supports DDR5 and LPDDR5X memory, with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. The i5-14400 supports both DDR4 and DDR5, also dual-channel, but the database lists no bandwidth figure. Both processors support ECC memory. PCIe connectivity shows a generational split: the AMD part uses PCIe Gen 4 with 16 lanes, while the Intel part uses PCIe Gen 5 with 16 lanes. The newer PCIe standard on the Intel chip allows for faster data transfer to compatible devices.

Socket and market positioning reinforce the design split. The P164i uses AMD Socket FP8 and targets the mobile segment, while the i5-14400 uses Intel Socket 1700 and targets desktop systems. The AMD part's integrated graphics are the Radeon 880M, which is a more advanced GPU than the Intel UHD Graphics 730. The release dates also differ, with the P164i dated 2026-03-08 and the i5-14400 dated 2024-01-07, making the AMD chip a newer entry in the database.
