AMD Ryzen AI 7 PRO 450 vs Intel Core Ultra 7 356H Comparison

Where Each One Wins

The recorded benchmark data splits these two mobile processors along a clear fault line. The AMD Ryzen AI 7 PRO 450 claims exactly one victory across the fifteen head-to-head tests, while the Intel Core Ultra 7 356H takes the remaining fourteen. That single AMD win comes in PassMark integer math, where the Ryzen scores 86,227 against Intel’s 83,111, a modest 3.7% advantage. Every other measured workload favors the Intel part, often by substantial margins.

The Intel Core Ultra 7 356H dominates in heavily threaded productivity and computational workloads. Cinebench R23 multi-core shows 18,395 versus 16,054 for AMD, a 12.7% gap. The PassMark multi-thread test widens that spread to 27.1%, with Intel at 33,978 and AMD at 24,779. Data compression follows the same pattern: Intel records 336,177 against AMD’s 294,298, a 12.5% difference. The largest single deltas appear in prime number finding (Intel 327 vs AMD 84, a 74.3% gap) and floating-point math (Intel 103,128 vs AMD 52,971, a 48.6% gap). These are not marginal edges; they represent fundamentally different throughput ceilings.

Single-core performance also leans Intel, though less dramatically. Cinebench R23 single-core shows Intel at 2,040 versus AMD’s 2,010, only 1.5% apart. PassMark single-thread confirms the direction at 4,072 versus 3,955, a 2.9% gap. The older Cinebench R15 single-core test shows a larger 27.4% Intel advantage (303 vs 220), but that test appears to amplify the difference beyond what newer workloads sustain. For lightly threaded tasks, the two chips are close, with Intel holding a consistent but small edge.

The use-case split is therefore straightforward. The AMD Ryzen AI 7 PRO 450 is competitive in integer-heavy single-stream work and little else from the measured set. The Intel Core Ultra 7 356H is the pick for rendering, encryption, physics simulation, compression, sorting, and any workload that scales across cores. The data does not show a single productivity category where AMD wins outright beyond that one integer test.

Head-to-Head Benchmarks

The fifteen recorded head-to-head tests reveal a lopsided contest. Intel wins fourteen, and the margins vary from negligible to overwhelming. The closest race is Cinebench R23 single-core, where Intel’s 2,040 barely edges AMD’s 2,010, a 1.5% difference. PassMark single-thread is nearly as tight: 4,072 versus 3,955, a 2.9% gap. These two results suggest that for everyday single-threaded responsiveness, the chips are effectively peers, with Intel holding a slight edge.

The multi-core tests tell a different story. Cinebench R23 multi-core gives Intel 18,395 against AMD’s 16,054, a 12.7% win. Cinebench R15 multi-core shows a larger 19.6% gap (3,055 vs 2,457). PassMark multi-thread lands at 33,978 for Intel versus 24,779 for AMD, a 27.1% difference. The pattern is consistent: the more threads a workload can use, the more Intel’s 16 physical cores outpace AMD’s 8 cores with simultaneous multithreading.

Specialized workloads amplify Intel’s advantage. PassMark floating-point math sees Intel at 103,128 versus AMD’s 52,971, a 48.6% blowout. PassMark physics shows Intel at 2,895 against AMD’s 1,337, a 53.8% gap. Prime number finding is the most extreme: Intel scores 327, AMD scores 84, a 74.3% deficit for the Ryzen. Data encryption favors Intel 26,345 to 14,925, a 43.3% margin. Extended instructions (SIMD-heavy code) go Intel’s way 27,898 to 20,778, a 25.5% gap.

Even tests that seem memory-bound favor Intel. Random string sorting sees Intel at 40,990 versus AMD’s 32,344, a 21.1% difference. Data compression gives Intel 336,177 against AMD’s 294,298, a 12.5% edge. The sole AMD victory, integer math at 86,227 versus 83,111, is a 3.7% margin that does not offset the breadth of Intel’s wins.

The aggregate picture is unambiguous. Intel’s average benchmark score of 41,215 sits 11.1% above AMD’s 37,093. The nearest rival comparisons confirm the tier: Intel sits near the AMD Ryzen AI 5 PRO 440 (0% delta) and the Intel Core Ultra 7 366H (-0.1%), while AMD’s closest peers are the Intel Core i9-12900T (-0.1%) and AMD Ryzen 7 160 (-0.1%). Both chips occupy the upper-middle tier of the database, but Intel sits measurably higher.

Specification Differences

The two processors diverge on nearly every core specification. AMD uses 8 cores and 16 threads; Intel uses 16 cores and 16 threads. Intel achieves its thread count without hyperthreading, while AMD relies on simultaneous multithreading to double its 8 physical cores. Base clocks are close: AMD at 2.00 GHz, Intel at 1.90 GHz. Boost clocks favor AMD at 5.10 GHz versus Intel’s 4.70 GHz, yet Intel still wins most benchmarks.

Thermal design power differs slightly, with AMD rated at 28 watts and Intel at 25 watts. Both target the mobile segment and are actively in production. The AMD part uses AMD Socket FP8; the Intel part uses Intel BGA 2540. Neither multiplier is unlocked. Memory support is identical in type (DDR5 and LPDDR5X) and bus width (dual-channel), but Intel’s memory bandwidth of 115.2 GB/s exceeds AMD’s 89.6 GB/s by 28.6%.

PCIe connectivity differs generationally. AMD provides PCIe Gen 4 with 16 CPU lanes; Intel provides PCIe Gen 5 with 12 CPU lanes. AMD supports ECC memory, Intel does not. The integrated graphics differ as well: AMD uses Radeon 860M, Intel uses Intel Xe3 Graphics. Both parts launched on the same date in the database, January 4, 2026. Neither has a recorded launch MSRP.

Architecture Differences

The silicon inside these chips comes from different foundries and process nodes. AMD fabricates the Ryzen AI 7 PRO 450 on TSMC’s 4 nm process, with a die size of 195 mm². Intel builds the Core Ultra 7 356H on its own 3 nm process, with no die size recorded. The process node advantage in raw density sits with Intel, though the architectural approach differs more fundamentally.

AMD’s architecture is Zen 5, under the codename Gorgon Point, belonging to the Ryzen AI PRO 400 generation. The design uses a hybrid of Zen 5 and Zen 5c cores, though the database does not specify the core mix. Cache is organized per core: 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3. Total L3 cache is 8 MB.

Intel’s architecture is Panther Lake, belonging to the Core Ultra Series 3 and the Ultra 7 (Panther Lake-H) generation. Cache is larger at every level: 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. That is 2.25 times AMD’s L3 capacity. The per-core L2 is 2.5 times larger. This cache disparity likely contributes to Intel’s dominance in data compression, sorting, and encryption, workloads that benefit from larger on-die working sets.

The core count difference is architectural too. Intel runs 16 physical cores without multithreading, which avoids the scheduling and resource contention overhead that simultaneous multithreading can introduce. AMD’s 8 cores with 16 threads rely on SMT to reach the same thread count. In the recorded benchmarks, Intel’s approach wins consistently in multi-threaded tests, suggesting that its 16 physical cores extract more throughput per thread than AMD’s SMT-enabled design.

The Verdict

The benchmark data supports a clear division of roles. The Intel Core Ultra 7 356H is the stronger processor for the vast majority of measured workloads. It wins 14 of 15 head-to-head tests, including all multi-core Cinebench runs, all PassMark multi-threaded tests, and every specialized workload except integer math. Its 16 physical cores, larger cache hierarchy (18 MB L3 versus 8 MB), and higher memory bandwidth (115.2 GB/s versus 89.6 GB/s) produce consistently higher throughput in rendering, encryption, physics, compression, floating-point math, and sorting. The average benchmark score of 41,215 versus 37,093, a 10.0% gap, summarizes the overall performance delta.

The AMD Ryzen AI 7 PRO 450 is not without merit. Its 5.10 GHz boost clock is the highest of the pair, and it wins the integer math test by 3.7%. For workloads that are integer-bound and lightly threaded, the AMD chip can match or slightly exceed Intel. Its 28-watt TDP is 3 watts higher than Intel’s, but it also supports ECC memory, a feature Intel lacks. The 8 MB L3 cache and 89.6 GB/s memory bandwidth are smaller than Intel’s, which shows in memory-sensitive tests.

The percentile ranking places Intel at 87 versus AMD’s 85, a modest gap in the overall CPU landscape. The nearest rival data reinforces this: Intel’s closest competitor is the AMD Ryzen AI 5 PRO 440 at 0% delta, while AMD’s closest competitor is the Intel Core i9-12900T at -0.1%. Both chips are competitive within their tier, but Intel occupies the higher position.

For a user prioritizing multi-core throughput, encryption, physics simulation, or any heavily threaded workload, the Intel Core Ultra 7 356H is the clear choice from the recorded data. For a user whose primary workload is integer math or who needs ECC memory support in a mobile processor, the AMD Ryzen AI 7 PRO 450 offers a specific, if narrow, advantage. The data does not support any other conclusion.
