AMD Ryzen AI Embedded P164i vs Intel Core 5 320 Comparison

AMD Ryzen AI Embedded P164i and Intel Core 5 320 are both active mobile processors from the 2026 lineup, but they represent divergent design philosophies. The AMD part uses an 8-core, 16-thread configuration with a 28 W thermal envelope, while the Intel part uses a 6-core, 6-thread setup at 15 W. The recorded benchmark data for the Intel Core 5 320 places it at the 72nd percentile among all CPUs, with an average benchmark score of 18023. The AMD Ryzen AI Embedded P164i holds the 50th percentile, though its average benchmark score is not recorded in the database. This comparison relies on the available Intel scores and the architectural specifications of both processors.

Where Each One Wins

The Intel Core 5 320 has a clear advantage in single-threaded workloads, based on its Cinebench results. It scores 276 in Cinebench R15 single-core, 771 in R20 single-core, and 1926 in R23 single-core. These numbers indicate strong per-core performance, which is typical for a processor with a 4.60 GHz boost clock. The PassMark single-thread score of 4045 reinforces this strength. For applications that rely on one or two threads, such as legacy software or lightly threaded productivity tools, the Intel part is the better choice.

The AMD Ryzen AI Embedded P164i, with its 8 cores and 16 threads, is positioned for multi-threaded throughput. While its benchmark scores are absent from the database, its architectural specifications point to a clear advantage in parallel workloads. The doubling of cores and threads, along with a 2.00 GHz base clock and 5.00 GHz boost clock, suggests it can handle concurrent tasks more effectively than the 6-core, 6-thread Intel part. The AMD processor also supports ECC memory, which is a feature the Intel part lacks, making it suitable for error-sensitive computing environments.

The Intel Core 5 320 wins in efficiency-oriented scenarios. Its 15 W TDP is substantially lower than the AMD part's 28 W TDP. This makes it a better fit for passively cooled or ultraportable designs where thermal headroom is limited. The Intel processor's 3 nm process node, built by Intel, contributes to this efficiency. The AMD part uses a 4 nm node from TSMC, which is slightly less advanced in terms of process geometry.

The AMD Ryzen AI Embedded P164i wins in memory bandwidth. It supports dual-channel memory with a bandwidth of 89.6 GB/s, while the Intel Core 5 320 is limited to single-channel memory at 59.7 GB/s. This 29.9 GB/s difference is significant for memory-intensive applications such as data compression or large dataset manipulation. The PassMark data compression score for the Intel part is 148779, but the AMD part's dual-channel design would likely improve on this in comparable workloads.

Architecture Differences

The core architectures are fundamentally different. The AMD Ryzen AI Embedded P164i uses the Gorgon Point codename with a Ryzen AI Embedded generation that combines Zen 5 and Zen 5c cores. This hybrid approach allows for a mix of high-performance and high-efficiency cores. The Intel Core 5 320 uses the Wildcat Lake codename with a Core 5 generation, which is a homogeneous 6-core design without performance or efficiency core differentiation.

Cache hierarchies diverge significantly. The AMD part has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 8 MB of L3 cache. The Intel part has 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The AMD design provides more L2 cache per core, which benefits workloads that repeatedly access small data sets. The Intel design has a larger L1 cache, but the total cache capacity is lower across the board.

Memory controllers are a major differentiator. The AMD processor supports dual-channel DDR5 and LPDDR5X memory with a peak bandwidth of 89.6 GB/s. The Intel processor supports single-channel DDR5 and LPDDR5X with a peak bandwidth of 59.7 GB/s. ECC memory is supported only on the AMD part, which is a critical feature for embedded and server-adjacent use cases.

PCIe connectivity also differs. The AMD Ryzen AI Embedded P164i provides Gen 4 with 16 lanes from the CPU, while the Intel Core 5 320 provides Gen 4 with 6 lanes. This gives the AMD part more than double the PCIe lane count, enabling more expansion cards, NVMe drives, or accelerators. The integrated graphics differ as well: the AMD part uses Radeon 880M, while the Intel part uses Intel Xe3 Graphics with 2 Xe cores.

Process technology is another split. The Intel part is built on a 3 nm node by Intel, while the AMD part is built on a 4 nm node by TSMC. The die size for the AMD part is 233 mm², while the Intel die size is not recorded. The AMD part uses the AMD Socket FP8, and the Intel part uses Intel BGA 1516, indicating different platform requirements.

The Verdict

The data indicates a clear split based on workload type. The Intel Core 5 320 is the stronger choice for single-threaded performance and low-power operation. Its Cinebench R23 single-core score of 1926 and PassMark single-thread score of 4045 are the only recorded benchmarks, but they show a capable per-core design. The 15 W TDP makes it suitable for fanless or battery-constrained systems where the 28 W AMD part would be too demanding.

The AMD Ryzen AI Embedded P164i is the better option for multi-threaded and memory-heavy workloads. Its 8 cores and 16 threads, combined with dual-channel memory at 89.6 GB/s, provide a structural advantage for parallel processing. The ECC memory support and 16 PCIe Gen 4 lanes make it more appropriate for embedded systems that require reliability and expandability.

For users prioritizing raw single-core speed and efficiency, the Intel Core 5 320 delivers. Its boost clock of 4.60 GHz and 3 nm process node support this. For users who need maximum thread count and memory bandwidth, the AMD part is the logical selection. The lack of benchmark scores for the AMD processor prevents a direct numerical comparison, but the specifications are sufficient to determine the use case.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries, so the comparison relies on the Intel Core 5 320's individual scores and the AMD part's specifications. The Intel processor's nearest rivals provide context for its performance level. It sits 0.2% above the AMD Ryzen 5 1600, 0.7% above the Intel Core 5 120U, 0.7% above the AMD Ryzen 5 3600XT, and 0.7% below the Intel Core i5-1334U. These deltas are small, indicating that the Intel Core 5 320 performs in line with these established processors.

The Intel Core 5 320's Cinebench R23 multi-core score of 6197 is its strongest multi-threaded result. Its single-core score of 1926 is comparatively strong, given the 6-thread limitation. The PassMark suite shows a multi-thread score of 15450 and a single-thread score of 4045. The floating point math score of 42440 exceeds the integer math score of 32323, indicating better floating-point throughput. The data encryption score of 10984 and extended instructions score of 13262 show moderate capabilities in these areas.

For the AMD Ryzen AI Embedded P164i, the lack of benchmark scores is a gap in the database. However, the architectural data provides a basis for comparison. The 8-core, 16-thread design would be expected to outperform the Intel part in multi-threaded tests, given the thread count advantage. The dual-channel memory at 89.6 GB/s would also improve memory-bound benchmarks. The Intel part's 15 W TDP and 6-thread limitation suggest it would trail in any heavily parallel workload.

The single-core comparison is more favorable to Intel, as its 4.60 GHz boost clock and 3 nm process node are designed for high per-core performance. The AMD part's 5.00 GHz boost clock is higher on paper, but without benchmark results, the actual single-core performance cannot be confirmed. The recorded data shows the Intel part is competitive with its nearest rivals, all of which are older or lower-tier processors.
