AMD Ryzen AI 7 PRO 450 vs Intel Core Ultra 5 336H Comparison

Head-to-Head Benchmarks

The head-to-head dataset delivers a decisive split, with Intel taking 12 of 15 recorded comparisons. The margin of victory, however, varies dramatically by workload type. The most lopsided result is in prime number finding, where Intel's score of 299 crushes AMD's 84, a 71.9% advantage. This suggests a fundamental difference in how each processor handles iterative integer workloads. Physics simulation shows a similar pattern, with Intel doubling AMD's score of 1337 to reach 2682, a 50.1% gap. Floating-point math also favors Intel heavily: 82415 versus 52971, a 35.7% lead.

Cinebench results paint a more nuanced picture. In the R15 multi-core test, AMD narrowly edges out Intel by 1.6%, scoring 2457 against 2418. But the newer R23 benchmark tells a different story. Intel's 23991 score is 33.1% ahead of AMD's 16054. The single-core results are even more pronounced in Intel's favor. R15 single-core shows Intel at 341 versus AMD's 220, a 35.5% gap, while R23 single-core widens to 40.7% with Intel at 3387 and AMD at 2010. These single-core deltas are among the largest in the entire comparison.

AMD's wins, while fewer, are notable for their specificity. The largest is in integer math, where AMD scores 86227 against Intel's 62070, a 38.9% advantage. Data compression also goes to AMD at 294298 versus 280340, a 5% edge. These are the only two Passmark tests where AMD leads, aside from the narrow R15 multi-core result.

The remaining Passmark tests favor Intel with varying intensity. Data encryption shows Intel at 21291, 29.9% ahead of AMD's 14925. Extended instructions favor Intel by 15.3% (24542 versus 20778). Random string sorting is closer, with Intel ahead by 6% (34402 versus 32344). Single-thread performance is nearly identical, with Intel's 4013 barely ahead of AMD's 3955, a 1.4% margin that appears twice in the dataset under different test labels. Overall multithreaded performance in Passmark goes to Intel at 28545, which is 13.2% ahead of AMD's 24779.

Architecture Differences

The two processors diverge sharply at the architectural level. AMD's Ryzen AI 7 PRO 450 uses Zen 5 cores under the Gorgon Point codename, manufactured on a 4 nm process at TSMC. Intel's Core Ultra 5 336H uses Panther Lake architecture on a 3 nm process at Intel's own foundry. This process difference likely contributes to the measured performance characteristics, though the data does not isolate process effects from core design choices.

Core counts differ substantially. AMD provides 8 cores and 16 threads. Intel provides 16 cores and 16 threads, meaning Intel's core count doubles AMD's but thread counts match. This implies Intel relies on more physical cores without simultaneous multithreading, while AMD uses fewer cores with two threads per core. The cache hierarchy reinforces this divergence. AMD allocates 80 KB of L1 per core and 1 MB of L2 per core, with 8 MB of shared L3. Intel allocates 192 KB of L1 per core and 2.5 MB of L2 per core, with 18 MB of shared L3. Intel's per-core cache allocations are substantially larger, and its total L3 is more than double AMD's.

Clock speeds tell a mixed story. AMD has a higher boost clock at 5.10 GHz versus Intel's 4.60 GHz, but a slightly higher base clock at 2.00 GHz versus 1.90 GHz. Despite the clock advantage, Intel wins most single-threaded tests, suggesting IPC (instructions per clock) differences favor Intel's Panther Lake design. Power envelopes are close, with AMD rated at 28 watts TDP and Intel at 25 watts.

Memory bandwidth favors Intel. Both support DDR5 and LPDDR5X over dual-channel buses, but Intel's rated bandwidth is 115.2 GB/s versus AMD's 89.6 GB/s. AMD supports ECC memory while Intel does not. PCIe connectivity also differs: AMD provides Gen 4 with 16 lanes from the CPU, while Intel provides Gen 5 with 12 lanes. Integrated graphics are distinct as well, with AMD using Radeon 860M and Intel using Xe3 Graphics. Both use different sockets: AMD Socket FP8 versus Intel BGA 2540. AMD's die size is listed at 195 mm², while Intel's die size is not recorded in the database.

Where Each One Wins

The benchmark distribution suggests clear workload affinities. Intel's Core Ultra 5 336H dominates in rendering and general compute. The Cinebench R23 multi-core result at 23991 indicates strong sustained multithreaded performance for tasks like video encoding, 3D rendering, and compilation. The single-core advantage of 40.7% in R23 makes Intel the stronger choice for lightly threaded applications that depend on raw single-thread speed, such as legacy software, scripting, and interactive workloads.

Intel also leads in math-heavy tasks. The floating-point score of 82415, the prime number finding score of 299, and the physics simulation score of 2682 all point to strong numerical throughput. Data encryption at 21291 and extended instructions at 24542 reinforce this pattern. For scientific computing, simulation, or cryptographic workloads, the data consistently favors Intel.

AMD's wins concentrate in integer operations and compression. The integer math score of 86227 is 38.9% ahead, which is the largest margin in either direction across all tests. Data compression at 294298 suggests AMD handles entropy-heavy workloads efficiently. The narrow R15 multi-core victory of 1.6% indicates that in certain legacy benchmark conditions, AMD can match or slightly exceed Intel's multicore throughput despite the larger core count on Intel's side.

Single-thread performance in Passmark is effectively a tie, with Intel only 1.4% ahead. This contrasts sharply with the Cinebench single-core results, where Intel leads by over 35%. The discrepancy between benchmark suites suggests that the two processors respond differently to specific instruction patterns, and the choice of benchmark methodology can substantially alter the perceived performance gap.

The Verdict

The recorded data consistently favors Intel's Core Ultra 5 336H for most compute scenarios. Intel wins 12 of 15 head-to-head comparisons, including all major Cinebench results and the majority of Passmark tests. The R23 multi-core lead of 33.1% and single-core lead of 40.7% indicate that Intel is faster in both heavily threaded and lightly threaded rendering-style workloads. The math and physics results reinforce this, with Intel ahead by 35.7% in floating-point math and 50.1% in physics simulation.

AMD's Ryzen AI 7 PRO 450 is the better choice for integer-heavy processing. The 38.9% integer math advantage is substantial, and the 5% data compression lead suggests AMD handles compression workloads with greater efficiency. The R15 multi-core win, while narrow at 1.6%, shows AMD can compete in legacy benchmark scenarios. AMD also offers ECC memory support and a higher boost clock of 5.10 GHz, which may matter for specific reliability-sensitive deployments.

For users running rendering, simulation, encryption, or general-purpose compute, the data points clearly to Intel. For workloads dominated by integer arithmetic or compression, AMD holds the advantage. The overall average benchmark scores reflect this split: AMD's average is 37093 against Intel's 34485, despite Intel winning the majority of individual tests. This apparent contradiction stems from AMD's large integer win offsetting many smaller Intel victories. The percentile rankings are close, with AMD at the 85th percentile and Intel at the 84th percentile of all CPUs in the database.
