AMD Ryzen AI Embedded P185 vs Intel Core Ultra 5 225 Comparison

Architecture Differences

The AMD Ryzen AI Embedded P185 and Intel Core Ultra 5 225 represent fundamentally different design philosophies. The AMD part uses the Gorgon Point codename and belongs to the Ryzen AI Embedded generation built on Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process at TSMC with a die size of 233 mm². The Intel Core Ultra 5 225 uses the Arrow Lake architecture, specifically Arrow Lake-S, and is built on a 3 nm process, also at TSMC, with a die size of 243 mm² and 17,800 million transistors.

The core configurations differ sharply. The AMD chip packs 12 cores and 24 threads, while the Intel chip has 10 cores and 10 threads. That means the AMD part relies on simultaneous multithreading to double its thread count, while the Intel part runs one thread per core. The AMD processor operates with a base clock of 2.00 GHz and boosts to 5.10 GHz. The Intel processor starts at 3.30 GHz and boosts to 4.90 GHz. Higher base clocks on the Intel side suggest better idle-to-load responsiveness, but the AMD part has a higher peak boost.

Cache hierarchies also diverge. The AMD processor allocates 80 KB of L1 per core and 1 MB of L2 per core, with 16 MB of shared L3. The Intel processor allocates 192 KB of L1 per core and 3 MB of L2 per core, with 20 MB of shared L3. The larger per-core caches on the Intel side reflect its different core topology, while the AMD part relies on its larger thread count to keep more work in flight.

Memory support differs as well. The AMD chip supports DDR5 and LPDDR5X over a dual-channel bus, with a recorded memory bandwidth of 89.6 GB/s and ECC support enabled. The Intel chip supports DDR5 only over a dual-channel bus, with a higher recorded memory bandwidth of 102.4 GB/s but no ECC support. PCIe connectivity goes to Gen 4 with 16 lanes on the AMD side, while the Intel side provides Gen 5 with 20 lanes.

Integrated graphics differ. The AMD part carries a Radeon 890M, while the Intel part uses Arc Xe-LPG Graphics with 16 execution units. The AMD part targets the mobile segment with a 28 W TDP and uses AMD Socket FP8. The Intel part targets the desktop segment with a 65 W TDP and uses Intel Socket 1851. The AMD part was released later, dated 2026-02-28, while the Intel part was released on 2025-01-06. Neither processor has an unlocked multiplier.

The AMD part also holds a higher overall percentile ranking at 93 versus 85, and a higher average benchmark score of 62839 versus 36938.

Head-to-Head Benchmarks

The largest AMD win comes in PassMark integer math. The AMD Ryzen AI Embedded P185 scores 117832 against 65345 for the Intel Core Ultra 5 225, a delta of 80.3%. This is the single biggest performance gap in either direction across the entire comparison. Data compression is the second largest AMD win, with 374429 versus 302811, a 23.7% advantage. Random string sorting adds another AMD win at 40557 versus 36590, a 10.8% margin. The multithread score of 31817 versus 30459 gives AMD a 4.5% win, which is modest but consistent with its thread advantage.

The Intel Core Ultra 5 225 takes the largest single win in prime number finding, scoring 358 versus 129, a 64% lead. Floating point math goes to Intel at 92038 versus 70587, a 23.3% margin.

The Verdict

The data points to different buyers for each processor. The AMD Ryzen AI Embedded P185 is the better choice for multithreaded integer work. It wins multithread, integer math, data compression, and random string sorting, and it holds the 93rd percentile ranking with an average benchmark score of 62839. Its 28 W TDP and mobile segment designation make it suitable for compact systems where power draw matters. The 24 threads provide real headroom for parallel workloads.

The Intel Core Ultra 5 225 is the better choice for single-thread performance, floating point math, physics simulation, and encryption. Its single-thread score of 4412 leads by 9.9%, and its floating point score of 92038 leads by 23.3%. The 65 W TDP and desktop segment indicate a more traditional desktop part, and the 102.4 GB/s memory bandwidth plus PCIe Gen 5 support give it a platform-level advantage for memory-heavy tasks.

The Intel part wins more individual tests, but the AMD part wins the overall average benchmark score by a wide margin. The average benchmark score of 62839 for AMD versus 36938 for Intel reflects that the AMD part performs better across the broader set of measured workloads, even though Intel dominates specific categories. The choice comes down to workload type: integer and compression-heavy parallel tasks favor AMD, while single-thread, floating point, and encryption tasks favor Intel.
