Where Each One Wins

The Intel Core Ultra 5 235H is the clear winner for most compute-heavy workloads. It dominates in every PassMark category except physics. Data compression favors Intel by 31.1% (301979 versus 230392), encryption by 65.5% (23121 versus 13967), and extended instructions by 46.6% (23354 versus 15925). Integer math shows a narrower but still decisive lead: 74247 versus 60033, a 23.7% advantage. Random string sorting goes to Intel by 52.9% (36208 versus 23675).

The AMD Ryzen 5 5500X3D wins only in the PassMark physics test, scoring 2282 versus Intel’s 1985, a 13% advantage. That result suggests the AMD chip has a specific strength in physics simulation, which can matter in certain game engines or scientific workloads. However, the database shows this is an isolated win, not part of a broader trend.

For multi-threaded throughput, Intel’s lead is substantial. PassMark multithread scores 30091 versus 20363, a 47.8% difference. Single-thread performance also favors Intel heavily: 4359 versus 2941, a 48.2% gap. In practical terms, the Intel processor is faster across almost every measured task, while the AMD chip’s physics win is the only counterpoint.

Architecture Differences

The two processors come from completely different design philosophies. The Intel Core Ultra 5 235H is a 14-core, 14-thread mobile chip built on Arrow Lake-H architecture, using TSMC’s 3 nm process. It has no hyper-threading, so core and thread counts are equal. The AMD Ryzen 5 5500X3D is a 6-core, 12-thread desktop chip based on Zen 3 (Vermeer), using TSMC’s 7 nm process. AMD relies on simultaneous multithreading to reach 12 threads from 6 cores.

Cache designs differ sharply. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and a much larger 96 MB of shared L3. That large L3 on the AMD side is the signature X3D advantage, which helps with cache-sensitive workloads, though the benchmark data here does not show it translating into wins outside physics.

Memory support also diverges. Intel supports DDR5 and LPDDR5X at 102.4 GB/s bandwidth, while AMD is limited to DDR4 at 51.2 GB/s. PCIe capabilities differ as well: Intel offers Gen 5 with 8 CPU lanes, AMD offers Gen 4 with 20 CPU lanes. The AMD chip also supports ECC memory, which Intel does not.

The Intel chip runs at a higher boost clock (5.00 GHz versus 4.00 GHz) but a lower base clock (2.40 GHz versus 3.00 GHz). Its TDP is far lower at 28 W versus 105 W, reflecting its mobile design. The AMD chip has a larger die area at 74 mm², while Intel’s die size is not recorded.

Head-to-Head Benchmarks

The largest Intel win comes in floating-point math, where the 235H scores 93509 against the 5500X3D’s 34511, a 171% advantage. This is a massive margin and indicates a fundamental throughput difference in floating-point operations. Data encryption also shows a huge gap: 23121 versus 13967, a 65.5% lead for Intel.

Multi-threaded workloads strongly favor Intel. The PassMark multithread score is 30091 versus 20363, a 47.8% difference. Single-thread performance follows the same pattern: 4359 versus 2941, a 48.2% gap. These results are consistent with the Intel chip’s higher boost clock and newer architecture.

Random string sorting favors Intel by 52.9% (36208 versus 23675), and extended instructions by 46.6% (23354 versus 15925). Prime number finding shows a 40.6% Intel advantage (239 versus 170). Data compression is closer but still decisive: 301979 versus 230392, a 31.1% lead. Integer math shows the smallest Intel margin among its wins, at 23.7% (74247 versus 60033).

The AMD Ryzen 5 5500X3D’s only victory is in PassMark physics, where it scores 2282 against 1985. That 13% margin is notable but isolated. The database records 10 wins for Intel and 1 for AMD, so the overall picture is unambiguous.

The Verdict

The data points to the Intel Core Ultra 5 235H as the stronger processor for almost every measured task. It wins 10 of 11 benchmarks, with margins ranging from 23.7% to 171%. Its advantages in multi-threaded throughput, single-thread speed, memory bandwidth, and integrated graphics make it the better choice for general productivity, content creation, and any workload that benefits from high clock speeds and modern architecture.

The AMD Ryzen 5 5500X3D is the pick only if physics performance matters most, since it beats Intel by 13% in that single test. Its 96 MB of L3 cache and 20 PCIe Gen 4 lanes also give it platform-level appeal for cache-sensitive tasks or systems needing more expansion lanes. However, the benchmark results show no other area where AMD pulls ahead.

For a builder choosing between these two, the decision comes down to platform and workload. The Intel part is a low-power mobile chip with a 28 W TDP, suitable for laptops or compact systems. The AMD part is a desktop chip with a 105 W TDP, requiring a discrete GPU but offering ECC support and a larger cache. On raw performance, Intel dominates the recorded metrics. The only reason to pick AMD is the physics win or the specific platform features, such as ECC memory and the AM4 socket.
