AMD Ryzen AI 5 PRO 435 vs Intel Core 9 273PE Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the Intel Core 9 273PE, which wins 9 of the 11 recorded head-to-head tests. The Intel part leads by substantial margins in nearly every workload category, while the AMD Ryzen AI 5 PRO 435 secures only a narrow single-thread win.

The largest single gap comes in passmark_find_prime_numbers, where Intel scores 203 versus AMD's 57, a 71.9% advantage. This test stresses integer-heavy algorithm throughput, and the Intel processor's 12-core, 24-thread configuration with a 5.70 GHz boost clock delivers results the AMD 6-core part cannot approach. Similarly, passmark_physics shows a 68.1% Intel lead, with scores of 3120 versus 995. Physics simulation workloads tend to scale with core count and raw frequency, both of which favor the Intel chip.

Floating-point math follows the same pattern. Intel posts 107884 against AMD's 41114, a 61.9% deficit for the Ryzen. Integer math shows Intel at 139410 versus 60879, a 56.3% margin. Data encryption and compression also heavily favor Intel: 22719 versus 11267 in encryption (50.4% gap) and 405885 versus 232803 in compression (42.6% gap). Multithread performance, a key indicator for content creation and compilation, sees Intel score 36810 against AMD's 19091, a 48.1% difference. Random string sorting, a memory-latency sensitive test, gives Intel 45098 versus 24936, a 44.7% edge. Extended instruction workloads show Intel at 24630 versus 16724, a 32.1% lead.

The only category where AMD wins is single-thread performance, and the margin is small. AMD scores 3757 against Intel's 3650, a 2.9% delta. The AMD chip's Zen 5 architecture at 4.50 GHz boost delivers a modest single-core advantage despite the Intel part's higher 5.70 GHz boost clock, likely reflecting architectural efficiency differences between the two designs. This single-thread edge, however, does little to offset the sweeping multi-core dominance of the Intel processor.

Average benchmark scores reinforce the overall picture. The Intel Core 9 273PE averages 49845 across the recorded tests, placing it in the 90th percentile of all CPUs in the database. The AMD Ryzen AI 5 PRO 435 averages 37762, sitting in the 86th percentile. The 32% average score gap is consistent with the individual test results: Intel wins the heavy workloads decisively, while AMD's single-thread advantage is too narrow to shift the aggregate.

Architecture Differences

The two processors come from fundamentally different design philosophies and market positions. The AMD Ryzen AI 5 PRO 435 is a 6-core, 12-thread mobile processor built on TSMC's 4 nm process, using the Zen 5 architecture under the Gorgon Point codename. It belongs to the Ryzen AI PRO 400 generation, which mixes Zen 5 and Zen 5c cores, and is designed for the AMD Socket FP8 platform. The Intel Core 9 273PE is a 12-core, 24-thread desktop processor on Intel's 10 nm process, using the Bartlett Lake codename and fitting the Intel Socket 1700. Its generation is listed as Core 9 (Bartlett Lake).

Cache hierarchies differ significantly. Both parts allocate 80 KB of L1 cache per core and 1 MB of L2 per core on the AMD side versus 2 MB per core on Intel. The critical divergence is in L3: AMD provides only 4 MB total, while Intel features 36 MB of shared L3 cache. This 32 MB difference helps explain Intel's strong showing in memory-sensitive workloads like random string sorting, where larger shared cache reduces latency penalties.

Memory support also diverges. AMD supports DDR5 and LPDDR5X memory, while Intel supports DDR4 and DDR5. Both use dual-channel memory buses, and both record identical maximum memory bandwidth of 89.6 GB/s. Both support ECC memory. PCIe connectivity differs: AMD provides Gen 4 with 14 CPU lanes, while Intel provides Gen 5 with 16 CPU lanes, giving the Intel platform newer and wider I/O bandwidth.

Integrated graphics separate the two as well. AMD pairs the processor with a Radeon 840M, while Intel uses UHD Graphics 730. The recorded data does not include graphics benchmarks, so direct comparison of iGPU performance is not possible from this database. The market segments differ: AMD is positioned for mobile, Intel for desktop, and this is reflected in power characteristics. AMD's TDP is 28 watts versus Intel's 65 watts, a more than 2x difference that affects thermal and platform requirements.

Clock speeds tell a mixed story. Intel has the higher base clock at 2.30 GHz versus 2.00 GHz, and the higher boost clock at 5.70 GHz versus 4.50 GHz. Yet AMD still wins the single-thread test, suggesting Zen 5's instruction efficiency compensates for the 1.20 GHz boost deficit. Production status is Active for both. AMD's release date is recorded as 2026-01-04, while Intel's is 2026-03-08.

Where Each One Wins

The Intel Core 9 273PE dominates every multi-threaded and heavy compute workload in the dataset. Data compression, encryption, extended instructions, prime number finding, floating-point math, integer math, multithread, physics, and random string sorting all go to Intel with margins ranging from 32.1% to 71.9%. This makes Intel the clear choice for workloads that scale with core count, cache size, and raw throughput: rendering, video encoding, scientific computation, database processing, and software compilation. The 36 MB shared L3 and 12-core configuration provide the resources these tasks demand.

The AMD Ryzen AI 5 PRO 435 wins exactly one performance category: single-thread execution. Its 3757 score edges Intel's 3650 by 2.9%. For applications that rely primarily on single-core responsiveness, such as lightweight office tasks, basic web browsing, or legacy single-threaded software, the AMD part has a slight edge. However, the margin is small enough that real-world perceptible differences would likely be minimal.

Power efficiency is another area where AMD holds an advantage, though the database does not include direct power consumption measurements. AMD's 28 W TDP versus Intel's 65 W TDP indicates the mobile processor draws substantially less power. For battery-constrained mobile devices or compact systems with limited cooling, the AMD part is the more practical fit, even if it loses on raw performance.

The market segments reinforce this split. AMD targets mobile with Socket FP8, while Intel targets desktop with Socket 1700. A mobile processor competing against a desktop processor in benchmark scores is notable: the AMD chip achieves 86th percentile performance at 28 W, while Intel reaches 90th percentile at 65 W. The AMD part's nearest rivals include the AMD Ryzen AI Embedded P132 at 37804 average score, only 0.1% away, and the Intel Core 5 211E at 37829, 0.2% away. The Intel part's nearest rivals include the AMD Ryzen AI Max+ 388 at 49796, just 0.1% behind, and the Intel Core i5-14600KF at 49394, 0.9% behind.

The Verdict

The data points to a clear performance hierarchy: the Intel Core 9 273PE is the faster processor in nearly every measurable category. Its 12 cores, 24 threads, 36 MB L3 cache, and 5.70 GHz boost clock produce benchmark results that are 32% to 72% ahead of the AMD Ryzen AI 5 PRO 435 in heavy workloads. The 49845 average benchmark score versus 37762, and the 90th versus 86th percentile ranking, confirm that Intel is the higher-performing part overall.

The AMD Ryzen AI 5 PRO 435 is not without merit. It wins the single-thread test by 2.9%, uses a 28 W TDP compared to Intel's 65 W, and fits a mobile platform. For users prioritizing single-core speed and power efficiency in a mobile form factor, the AMD part is the sensible pick. The data shows no scenario where AMD wins a multi-threaded benchmark, so users whose workloads are heavily parallel should choose Intel without hesitation.

For desktop users building a system around Socket 1700 with DDR4 or DDR5 memory and PCIe Gen 5 connectivity, the Intel Core 9 273PE delivers dominant multi-core performance. The launch MSRP is $549. For mobile users on Socket FP8 with LPDDR5X memory and PCIe Gen 4, the AMD part offers competitive single-thread performance and a much lower power envelope. The choice reduces to platform and workload priorities: Intel for maximum throughput, AMD for efficiency and single-core responsiveness.
