AMD Ryzen 5 5500X3D vs Intel Core Ultra 9 185H Comparison

The Verdict

The benchmark data is decisive: the Intel Core Ultra 9 185H wins 9 of 11 head-to-head tests against the AMD Ryzen 5 5500X3D. The Intel part is the clear choice for compute-heavy workloads, especially those that scale with core count, floating-point math, and data compression. It leads by massive margins in several key tests, including a 112.3% advantage in floating-point math and a 63.7% lead in integer math.

The AMD Ryzen 5 5500X3D is not without merit, however. It takes both of its wins in tests that favor cache-sensitive, latency-bound operations. The AMD part wins in the prime-number search test by 27.6%, and in the physics simulation test by 14.3%. For users running physics-heavy applications or workloads that benefit from large, low-latency caches, the 5500X3D holds a narrow but real edge.

The database shows both processors sit at the 85th percentile among all CPUs, meaning they are not far apart in overall standing. However, the Intel's average benchmark score of 35,670 is lower than the AMD's 37,018, which reflects the AMD's strong performance in the few tests it wins. The Intel wins more tests, but the AMD's wins are more concentrated in specific areas.

For a mobile platform, the Intel is the more versatile choice. It ships with integrated graphics, while the AMD desktop part has none. The Intel also has a lower TDP of 45 watts versus the AMD's 105 watts, making it far more suitable for thin-and-light systems. If you need a processor for a laptop with broad compute capability, the Intel is the recommendation. If you are building a desktop where cache-heavy and physics-based workloads dominate, the AMD is the pick.

Where Each One Wins

The Intel Core Ultra 9 185H dominates in every multi-threaded and math-heavy benchmark. Its passmark multithread score of 29,376 is 44.3% higher than the AMD's 20,363. The data compression score of 339,489 is 47.4% higher than the AMD's 230,392, and encryption is 42% higher (19,827 vs. 13,967). The floating-point math result is the largest gap: 73,270 versus 34,511, a 112.3% lead. The single-thread score of 3,697 is 25.7% higher than the AMD's 2,941, proving the Intel also wins on lightly threaded performance.

The AMD Ryzen 5 5500X3D wins only where its large L3 cache matters. The 96 MB shared L3 cache, versus the Intel's 24 MB, gives it a decisive edge in data-hungry loops. The AMD scores 170 in the find prime numbers test, beating the Intel's 123 by 27.6%. It also wins the physics test, 2,282 versus 1,956, a 14.3% lead. These are the only two tests where the AMD's architecture compensates for its lower core count and clock speeds.

Head-to-Head Benchmarks

The most lopsided result is in floating-point math. The Intel scores 73,270, which is 112.3% higher than the AMD's 34,511. That is a more than doubling of performance. The Intel also shows a massive lead in integer math, 98,302 versus 60,033, a 63.7% advantage. These two tests show a fundamental difference in raw execution resources: the Intel has 16 cores and 22 threads, versus 6 cores and 12 threads on the AMD.

The data compression test also favors Intel heavily. The Intel scores 339,489 versus 230,392 for AMD, a 47.4% lead. Encryption is 42% higher for Intel (19,827 vs. 13,967). Random string sorting is 67.3% higher (39,598 vs. 23,675). The Intel's multithread advantage of 44.3% (29,376 vs. 20,363) is consistent across these parallel workloads.

The single-thread result is also Intel's. The Intel scores 3,697 in the passmark single thread test, versus 2,941 for the AMD, a 25.7% lead. This shows that the Intel's higher base and boost clocks, 3.90/5.10 GHz versus 3.00/4.00 GHz, provide a real single-core edge.

The AMD's two wins are narrower in percentage than the Intel's biggest wins. The AMD beats the Intel in find prime numbers with a score of 170 versus 123, a 27.6% delta. In the physics test, the AMD scores 2,282 against the Intel's 1,956, a 14.3% delta. The AMD's wins rely on its 96 MB L3 cache, which reduces memory latency for repetitive loops and physics calculations. The Intel wins the remaining 9 of 11 tests.

Specification Differences

The two processors differ in nearly every core specification. The Intel has 16 cores and 22 threads, while the AMD has 6 cores and 12 threads. The Intel's base clock is 3.90 GHz versus 3.00 GHz, and its boost clock is 5.10 GHz versus 4.00 GHz. The Intel's TDP is 45 watts, the AMD's is 105 watts. The Intel is a mobile part on the Intel BGA 2049 socket; the AMD is a desktop part on the AMD Socket AM4.

Cache configurations are starkly different. The Intel has 112 KB L1 per core and 2 MB L2 per core, while the AMD has 64 KB L1 and 512 KB L2. The shared L3 cache is the biggest difference: 24 MB on Intel versus 96 MB on AMD. Memory support differs: the Intel uses DDR5, and the AMD uses DDR4. The Intel's memory bandwidth is 89.6 GB/s, versus 51.2 GB/s. The AMD supports ECC memory; the Intel does not.

The PCIe support is also different. The Intel has PCIe Gen 5 with 8 lanes, while the AMD has PCIe Gen 4 with 20 lanes. In features, the Intel includes integrated Arc Xe-LPG Graphics, and the AMD has no iGPU. The production process is the same node size (7 nm), but the Intel is fabricated by Intel, and the AMD is fabricated by TSMC. The Intel was released in December 2023, while the AMD was released in June 2025. The Intel has a launch MSRP of $640; the AMD has no recorded launch MSRP.
