Head-to-Head Benchmarks

The recorded head-to-head data contains 11 benchmark comparisons, and the results are heavily skewed toward one side. The Intel Core 9 273PE takes 9 wins, while the AMD Ryzen AI 5 PRO 435G secures 2 wins. The single-threaded tests are the only category where AMD leads.

In passmark_single_thread, the AMD Ryzen AI 5 PRO 435G scores 3829 against Intel's 3650, a 4.9% advantage. This is the closest margin in the entire comparison and represents AMD's only competitive edge. The same delta appears in the duplicate passmark_singlethread test, confirming the result is consistent.

Every other benchmark favors Intel, often by substantial margins. The largest gap is in passmark_find_prime_numbers: Intel scores 203 versus AMD's 55, a 72.9% difference. This test heavily rewards Intel's higher thread count and core configuration. Passmark_physics shows a 68% gap (3120 versus 999), and passmark_floating_point_math shows a 59.7% gap (107884 versus 43494). Passmark_integer_math follows with a 54.3% deficit for AMD (139410 versus 63707).

The data_encryption test shows Intel at 22719 versus AMD's 12111, a 46.7% gap. Passmark_multithread records 36810 for Intel and 20285 for AMD, a 44.9% difference. Random_string_sorting sees Intel at 45098 against AMD's 27407, a 39.2% gap. Data compression shows 405885 versus 253484, a 37.5% deficit. Extended instructions complete the list with 24630 versus 18697, a 24.1% gap.

The average benchmark score tells the same story. Intel's average is 49845, while AMD's is 40718. Intel sits at the 90th percentile among all CPUs, and AMD sits at the 87th. The nearest rival data places Intel alongside the AMD Ryzen AI Max+ 388 (0.1% ahead), the Intel Core i5-14600KF (0.9% ahead), and within 1.2% of the Intel Core i9-13980HX and AMD Ryzen AI 9 HX PRO 370. AMD's nearest rivals are the Intel Xeon 6357P (0.2% behind), Intel Core 5 223PE (0.3% behind), Intel Core 7 253PE (0.4% behind), and Intel Core Ultra X7 368H (0.5% behind). These percentile positions confirm that both processors sit in the same performance class, but Intel has a clear internal advantage.

Architecture Differences

The two processors diverge significantly in their fundamental designs. The AMD Ryzen AI 5 PRO 435G uses 6 cores and 12 threads, built on the Gorgon Point codename from the Ryzen AI PRO 400 generation (Zen 5 / Zen 5c). It is fabricated on a 4 nm process at TSMC. The Intel Core 9 273PE uses 12 cores and 24 threads, based on the Bartlett Lake codename from the Core 9 generation, and is built on a 10 nm process at Intel.

Cache hierarchies differ substantially. Both share an 80 KB L1 per core, but AMD's L2 is 1 MB per core versus Intel's 2 MB per core. The L3 cache shows the biggest divergence: AMD has 4 MB total, while Intel has 36 MB shared. This ninefold difference in L3 capacity likely explains Intel's dominance in data-heavy workloads like compression and encryption.

Clock speeds favor Intel in both base and boost. AMD runs at 2.00 GHz base and 4.50 GHz boost. Intel runs at 2.30 GHz base and 5.70 GHz boost. Both have a 65 TDP, so the power envelope is identical, but Intel extracts more performance from it.

Memory support differs. AMD supports DDR5 only, while Intel supports both DDR4 and DDR5. Both use dual-channel memory with the same 89.6 GB/s bandwidth. Both support ECC memory. PCIe lanes favor Intel: Gen 5 with 16 lanes (CPU only) versus AMD's Gen 4 with 10 lanes (CPU only). This gives Intel more headroom for expansion and faster peripheral connectivity.

Integrated graphics also differ. AMD uses the Radeon 840M, while Intel uses UHD Graphics 730. The benchmark data does not include graphics tests, so the comparison is limited to CPU workloads. Socket compatibility diverges as well: AMD uses Socket AM5, Intel uses Socket 1700. Neither processor has an unlocked multiplier. AMD's production status is Active with a release date of 2026-03-01, and Intel's is Active with a release date of 2026-03-08, one week later.

Where Each One Wins

The AMD Ryzen AI 5 PRO 435G wins exclusively in single-threaded performance. The 4.9% margin in passmark_single_thread suggests that for tasks relying on a single core, such as older software, lightly threaded applications, or certain real-time workloads, AMD holds a measurable advantage. However, the margin is modest compared to Intel's multi-threaded leads.

The Intel Core 9 273PE wins in every multi-threaded and data-intensive category. The 72.9% lead in prime-number finding indicates strong integer throughput per core. The 68% lead in physics simulations points to better floating-point efficiency when combined with the higher core count. Data encryption and compression show 46.7% and 37.5% leads respectively, which means workloads involving file archiving, database operations, or cryptographic processing will complete faster on Intel.

The extended instructions test, with a 24.1% gap, shows Intel handles SIMD and specialized instruction sets better. Integer math at 54.3% and floating-point math at 59.7% both favor Intel by wide margins, indicating that scientific computing, financial modeling, and content rendering workloads will lean heavily toward Intel. Random string sorting, a proxy for memory-access patterns and cache efficiency, shows a 39.2% lead for Intel, consistent with its larger L3 cache.

The overall benchmark average reinforces this split. Intel's average score of 49845 is 22.4% higher than AMD's 40718. The percentile ranks (90 versus 87) place both in the upper tier of desktop processors, but Intel occupies a higher position within that tier.

The Verdict

The data clearly indicates that the Intel Core 9 273PE is the stronger processor for the vast majority of workloads. Its 12 cores and 24 threads double AMD's 6 cores and 12 threads, and the benchmark results reflect this advantage across every multi-threaded test. The 36 MB shared L3 cache versus 4 MB total L3 gives Intel a structural advantage in data-intensive tasks that the benchmark scores confirm.

The AMD Ryzen AI 5 PRO 435G has one specific strength: single-threaded performance. The 4.9% lead in passmark_single_thread is real but narrow. For users whose primary workloads are purely single-threaded, AMD offers a slight edge. However, the rest of the comparison shows Intel leading by margins ranging from 24.1% to 72.9%, which are far larger than AMD's single-thread advantage.

The Intel Core 9 273PE also has a launch MSRP of $549. The AMD part has no launch MSRP recorded in the database. Beyond pricing, the architectural differences favor Intel in connectivity: Gen 5 PCIe with 16 lanes versus Gen 4 with 10 lanes, and dual memory support (DDR4 and DDR5) versus DDR5 only. Both processors share the same TDP and memory bandwidth, so power and memory throughput are not differentiators.

For multi-threaded rendering, compilation, scientific computing, data analysis, or any workload that scales with cores and cache, the Intel Core 9 273PE is the clear choice based on the recorded data. For single-threaded responsiveness in legacy applications or lightly threaded software, the AMD Ryzen AI 5 PRO 435G provides a modest but measurable benefit. The overall average benchmark score, percentile rank, and the 9-to-2 win count all point to Intel as the superior processor in this comparison.
