AMD Ryzen AI Embedded P185 vs Intel Core i9-13900KF Comparison

The AMD Ryzen AI Embedded P185 and the Intel Core i9-13900KF represent two fundamentally different approaches to processing power, and the benchmark data reflects that divergence clearly. Across all eleven head-to-head tests in the PassMark suite, the Intel Core i9-13900KF holds a decisive advantage, though the size of that lead varies significantly by workload, revealing distinct strengths in each chip's design.

Head-to-Head Benchmarks

The most dramatic gap appears in memory and I/O heavy tasks. In passmark_data_compression, the Intel Core i9-13900KF scores 786218 against the AMD's 374429, a -52.4% delta for the AMD part. Similarly, passmark_random_string_sorting shows the Intel processor at 86510 versus 40557, a -53.1% difference. These results indicate that the Intel chip's larger cache and higher memory bandwidth allow it to move and manipulate data at a much faster rate.

Floating-point and integer math workloads also heavily favor Intel. In passmark_floating_point_math, the Intel scores 150869 versus 70587 for AMD, a -53.2% delta. passmark_integer_math shows 206859 for Intel and 117832 for AMD, a -43% gap. These results are consistent with the Intel part's higher boost clock speed and greater core count, which allow it to push through compute-heavy instructions more quickly.

The single-threaded results narrow the gap considerably. In passmark_single_thread, the Intel Core i9-13900KF scores 4584, while the AMD Ryzen AI Embedded P185 scores 3977, a -13.2% delta. This is the closest contest in the entire benchmark set, suggesting that while Intel has the raw performance lead, the AMD processor's Zen 5 architecture delivers competitive per-core efficiency. The passmark_find_prime_numbers test shows a similar pattern, with Intel at 225 and AMD at 129, a -42.7% difference, indicating that even in integer-heavy single-threaded tasks, the Intel chip's clock speed advantage is significant.

In multithreaded workloads, the Intel part maintains its dominance. The passmark_multithread score is 57729 for Intel versus 31817 for AMD, a -44.9% delta. This aligns with the core count disparity: the Intel has 24 cores and 32 threads, while the AMD has 12 cores and 24 threads. The passmark_data_encryption test shows a -57.5% delta, with Intel at 46186 and AMD at 19612, the largest relative gap of any test, suggesting that the Intel processor's AES-NI capabilities and higher thread count are particularly effective here.

The passmark_extended_instructions benchmark results in 46084 for Intel and 26544 for AMD, a -42.4% delta. The passmark_physics test scores 2956 for Intel and 1772 for AMD, a -40.1% difference. Across all eleven tests, the AMD processor records zero wins, while Intel wins all eleven.

Architecture Differences

The two processors are built on completely different foundational designs. The AMD Ryzen AI Embedded P185 uses the Gorgon Point codename and belongs to the Ryzen AI Embedded (Zen 5 / Zen 5c) generation, manufactured on a 4 nm process at TSMC. The Intel Core i9-13900KF is part of Raptor Lake-S, built on Intel's 10 nm process. This process node difference is significant; the AMD's smaller node allows for higher transistor density and potentially better power efficiency per operation.

Cache hierarchies differ notably. Both have 80 KB of L1 per core, but the AMD has 1 MB of L2 per core, while the Intel has 2 MB per core. The L3 cache is a more substantial difference: the AMD has 16 MB of total L3, while the Intel has 36 MB shared. This larger shared L3 cache on the Intel part is likely a major factor in its data-heavy benchmark wins, as it can hold more frequently accessed data closer to the cores.

Core counts and threading also diverge sharply. The AMD has 12 cores and 24 threads, while the Intel has 24 cores and 32 threads. This 2x core advantage for Intel directly explains its multithreaded benchmark performance. The AMD's base clock is 2.00 GHz with a boost clock of 5.10 GHz, whereas the Intel runs at a 3.00 GHz base and 5.80 GHz boost. The Intel's higher clock speeds, combined with more cores, create a compound performance advantage.

Memory support differs in type: the AMD supports DDR5 and LPDDR5X with a memory bandwidth of 89.6 GB/s, while the Intel supports DDR4 and DDR5 with no listed bandwidth figure. Both use dual-channel memory buses. The AMD has Gen 4 PCIe with 16 lanes, while the Intel has Gen 5 PCIe with 20 lanes, which is a significant expansion capability difference. The AMD includes integrated Radeon 890M graphics, while the Intel has no integrated graphics. The AMD's TDP is 28 W versus the Intel's 125 W, indicating a vast difference in power envelope and thermal requirements.

Where Each One Wins

The Intel Core i9-13900KF wins in every single benchmark test in the head-to-head comparison. Its most substantial victories are in data encryption (-57.5% delta), data compression (-52.4%), floating-point math (-53.2%), and random string sorting (-53.1%). These are all workloads that benefit from a combination of high core count, large cache, and high clock speeds. The Intel part is also superior in multithreaded tasks (-44.9%), making it the clear choice for heavily parallel workloads like video rendering, scientific computing, and software compilation.

The AMD Ryzen AI Embedded P185, while losing all head-to-head tests, shows its closest relative performance in single-threaded tasks (-13.2% delta). This indicates that its Zen 5 architecture is efficient on a per-core basis, even if it cannot match the Intel's absolute clock speed. The AMD also offers integrated Radeon 890M graphics, which is a feature the Intel lacks entirely, making it the only choice for systems requiring a GPU without a discrete add-in card. The AMD's dramatically lower TDP of 28 W versus 125 W suggests it is designed for power-constrained environments, making it a candidate for compact or embedded systems where the Intel's performance lead cannot be utilized due to thermal or power limits.

The Verdict

The data is unambiguous: the Intel Core i9-13900KF is the superior processor on a pure performance basis. It wins all eleven head-to-head benchmarks, with deltas ranging from -13.2% in single-thread to -57.5% in data encryption. Its 24 cores, 32 threads, 5.80 GHz boost clock, and 36 MB of L3 cache combine to deliver a comprehensive performance advantage across every measured workload. For users building a desktop system where maximum compute throughput is the sole priority, the Intel part is the data-driven choice.

The AMD Ryzen AI Embedded P185, however, is not without its own rationale. Its 28 W TDP makes it a fundamentally different class of product, targeting mobile or embedded applications where power efficiency is paramount. Its support for LPDDR5X memory and integrated Radeon 890M graphics further cement its role as a self-contained system-on-chip for portable or compact designs. The closest benchmark margin in single-threaded work suggests that for lightly threaded tasks, the Zen 5 architecture is highly capable. The choice between these two CPUs comes down to platform: one is a desktop performance leader, the other is a low-power embedded solution with a strong performance-per-watt profile. There is no single "winner" — the correct pick depends entirely on whether the target system prioritizes raw speed or power efficiency.
