AMD Ryzen AI Embedded P185 vs Intel Core Ultra 5 245HX Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive picture: the Intel Core Ultra 5 245HX wins 10 of 11 head-to-head tests, while the AMD Ryzen AI Embedded P185 takes only one. The most dramatic gap appears in the PassMark find prime numbers test, where Intel scores 359 against AMD's 129, a 64.1% advantage. This is the largest delta recorded between the two processors and highlights a substantial difference in single-thread integer throughput for certain workloads.

Data encryption also favors Intel heavily. The Core Ultra 5 245HX delivers a score of 30022 compared to 19612 for the AMD part, a 34.7% lead. Floating point math follows a similar pattern: Intel posts 120735 versus AMD's 70587, a 41.5% margin. These results suggest Intel's architecture handles mathematically intensive tasks with notably higher throughput.

The physics test shows Intel ahead by 29.8%, scoring 2526 against AMD's 1772. Multithread performance also goes Intel's way, with 38069 versus 31817, a 16.4% gap. Random string sorting shows Intel at 47616 against 40557, a 14.8% edge. Extended instructions favor Intel by 15%, with scores of 31212 and 26544 respectively.

Single-thread performance is another Intel win. The Core Ultra 5 245HX scores 4481 in the PassMark single thread test, while the Ryzen AI Embedded P185 manages 3977, an 11.2% difference. Data compression is closer: Intel leads with 393071 versus 374429, a modest 4.7% margin.

The AMD processor's sole victory comes in integer math, where it scores 117832 against Intel's 92150. That represents a 27.9% advantage and demonstrates that AMD's Zen 5 cores can outperform Intel in specific integer workloads. However, this single win does little to offset Intel's dominance across the broader test suite.

The average benchmark scores reflect this overall disparity. Intel's Core Ultra 5 245HX sits at 48287, while the Ryzen AI Embedded P185 trails at 62839, though this figure is skewed by the different benchmark sets each chip was tested with. The percentile rankings show AMD at 93 versus Intel at 90, indicating the AMD part ranks higher among all CPUs despite losing most direct comparisons.

The Verdict

The data points to the Intel Core Ultra 5 245HX as the stronger performer in nearly every measured category. Its 10-to-1 win ratio in head-to-head tests is unambiguous. Applications relying on encryption, floating point math, prime number calculations, or physics simulations will see substantial gains with the Intel part. The 34.7% encryption advantage alone could matter for workloads involving secure data processing or compression tasks.

The AMD Ryzen AI Embedded P185 retains a clear niche: integer math. The 27.9% lead in that test indicates the Zen 5 architecture handles integer-heavy code more efficiently. Workloads such as certain database operations, financial modeling, or specific compiler tasks could benefit from this advantage. However, the AMD part trails in multithread performance by 16.4%, which limits its appeal for broadly threaded applications.

For users prioritizing overall throughput, the Intel Core Ultra 5 245HX is the data-supported choice. Its wins span single-thread and multithread tests, covering both lightly threaded and heavily parallel workloads. The AMD processor makes sense only for specialized integer-heavy scenarios where its 117832 score provides a meaningful edge.

The Intel part also comes from a newer release window, with its production status active and a launch date in early 2025. The AMD processor's release date follows in 2026. Both are mobile segments, but the Intel chip's higher TDP of 55 watts against AMD's 28 watts suggests it trades power for performance, a tradeoff the benchmark results appear to confirm.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI Embedded P185 uses the Gorgon Point codename and belongs to the Ryzen AI Embedded generation based on Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC with a die size of 233 mm². The Intel Core Ultra 5 245HX uses the Arrow Lake architecture, specifically Arrow Lake-HX, and is fabricated on a 3 nm process, also at TSMC, with a die size of 243 mm².

Core configurations differ sharply. The AMD part offers 12 cores and 24 threads, relying on simultaneous multithreading to double its thread count. The Intel part provides 14 cores but only 14 threads, indicating no hyperthreading support. This means Intel's higher core count does not translate into a thread advantage; AMD actually offers 10 more threads overall. Despite that, Intel wins the multithread benchmark by 16.4%, suggesting its individual cores are substantially more efficient.

Cache hierarchies also diverge. AMD allocates 80 KB of L1 per core and 1 MB of L2 per core, with a 16 MB L3 cache. Intel provides 192 KB of L1 per core and 3 MB of L2 per core, with a larger 24 MB shared L3. The larger per-core caches on the Intel side likely contribute to its single-thread and encryption performance advantages.

The process node difference is notable. Intel's 3 nm process is more advanced than AMD's 4 nm, potentially enabling higher clock speeds at lower power draw per transistor. Both chips reach the same 5.10 GHz boost clock, but Intel starts from a 3.10 GHz base clock versus AMD's 2.00 GHz base clock. That 1.10 GHz base clock gap helps explain Intel's consistent single-thread wins.

Memory support also differentiates the pair. AMD supports DDR5 and LPDDR5X with a dual-channel bus and 89.6 GB/s bandwidth. Intel supports only DDR5 with a dual-channel bus but achieves 102.4 GB/s bandwidth. The higher memory bandwidth on the Intel side could benefit data-intensive workloads like compression and encryption.

PCIe capabilities favor Intel as well. AMD offers Gen 4 with 16 lanes, while Intel provides Gen 5 with 20 lanes. The newer PCIe standard and additional lanes give Intel more headroom for high-speed peripherals and expansion. Integrated graphics differ too: AMD uses Radeon 890M, while Intel pairs with Arc Xe-LPG Graphics 48EU.

Specification Differences

The core and thread counts represent the most visible specification gap. AMD provides 12 cores and 24 threads; Intel provides 14 cores and 14 threads. The Intel part has two more physical cores but ten fewer logical threads. Base clocks differ substantially, with Intel at 3.10 GHz and AMD at 2.00 GHz. Both share a 5.10 GHz boost clock.

Thermal design power separates the two clearly. AMD is rated at 28 watts, while Intel draws 55 watts. The 27 watt difference reflects Intel's higher performance ambitions and likely contributes to its benchmark superiority. Socket types also differ: AMD uses Socket FP8, Intel uses BGA 2114.

The process node moves from AMD's 4 nm to Intel's 3 nm. Transistor counts are listed only for Intel at 17,800 million; no transistor count appears for AMD. Die sizes are close, with AMD at 233 mm² and Intel at 243 mm². Cache per core shows Intel's advantage: 192 KB L1 versus 80 KB, and 3 MB L2 versus 1 MB. Total L3 goes to Intel at 24 MB shared versus AMD's 16 MB.

Memory bandwidth favors Intel at 102.4 GB/s against AMD's 89.6 GB/s. ECC memory support exists only on the AMD side, a feature that could matter for embedded or reliability-focused deployments. PCIe generation and lane counts give Intel the edge with Gen 5 and 20 lanes versus AMD's Gen 4 and 16 lanes. Intel also has an unlocked multiplier, while AMD's is locked. Intel's part number is listed as SRVFM; AMD's is unknown.
