AMD Ryzen AI 5 PRO 435 vs Intel Core i5-14400 Comparison

Head-to-Head Benchmarks

The recorded data presents a clear performance hierarchy between the AMD Ryzen AI 5 PRO 435 and the Intel Core i5-14400. Across the eleven shared PassMark tests, Intel secures nine victories while AMD claims two. The magnitude of Intel's wins is substantial, with the largest deltas appearing in floating-point and integer workloads.

Intel's most decisive advantage emerges in `passmark_floating_point_math`, where it scores 61549 against AMD's 41114, a 33.2% gap. This pattern repeats across other compute-heavy tests. In `passmark_data_encryption`, Intel posts 16731 versus 11267, a 32.7% lead. The `passmark_find_prime_numbers` test shows Intel at 80 against AMD's 57, a 28.7% difference, while `passmark_physics` shows the same 28.7% gap with 1396 versus 995. Integer math follows the trend: Intel reaches 82017, AMD manages 60879, a 25.8% difference.

The data compression test delivers Intel a 314995 score against AMD's 232803, a 26.1% margin. In `passmark_multithread`, Intel scores 25080 versus 19091, a 23.9% lead. Random string sorting shows Intel at 32346 against 24936, a 22.9% advantage. Extended instructions complete Intel's sweep of the heavier workloads with 19816 versus 16724, a 15.6% gap.

AMD's two wins are narrow but consistent across the duplicated single-thread tests. Both `passmark_single_thread` and `passmark_singlethread` record identical scores of 3757 for AMD and 3741 for Intel, giving AMD a 0.4% edge. This is a marginal victory, yet it indicates that AMD's Zen 5 design achieves slightly better single-core throughput despite Intel's higher boost clock.

The average benchmark scores place AMD at 37762 and Intel at 32115, an apparent contradiction given Intel's dominance in the head-to-head tests. This discrepancy reflects the different benchmark suites included in each processor's database entry. AMD's percentile ranking of 86 versus Intel's 82 further complicates the picture, suggesting that across the broader database of processors, AMD's aggregate performance lands higher.

Where Each One Wins

The workload split follows the core-count and architecture differences between the two chips. Intel's 10 cores and 16 threads give it a structural advantage in parallel tasks. The multithread score of 25080 versus 19091 confirms this, as do the consistent double-digit margins across all multi-threaded PassMark workloads. Applications that scale with core count, such as rendering, video encoding, and scientific computation, will favor Intel based on this data.

AMD's single-thread victory, though small, points to a different strength. The 0.4% lead in both single-thread benchmarks suggests that lightly threaded workloads, such as legacy applications, certain games, and interactive desktop tasks, may see near-parity or slight AMD preference. The Ryzen AI 5 PRO 435 also carries a 28 W TDP compared to Intel's 65 W, which indicates a power efficiency profile that favors thermally constrained systems.

The `passmark_extended_instructions` gap of 15.6% is Intel's smallest victory, hinting that AMD's Zen 5 architecture handles SIMD and specialized instruction sets more competitively than in raw arithmetic throughput. This could matter for workloads that rely on AVX-512 or similar extensions, though the recorded data does not specify which instruction sets are exercised.

Intel's `passmark_data_compression` lead of 26.1% and `passmark_random_string_sorting` lead of 22.9% both involve memory access patterns and cache behavior. Intel's 20 MB shared L3 cache versus AMD's 4 MB L3 provides a plausible explanation for these results, as larger caches reduce memory latency for data-intensive operations.

Specification Differences

The two processors differ across nearly every core specification. AMD provides 6 cores and 12 threads, while Intel provides 10 cores and 16 threads. Base clocks differ at 2.00 GHz for AMD and 2.50 GHz for Intel. Boost clocks reach 4.50 GHz on AMD and 4.70 GHz on Intel.

Thermal design power presents a major divergence: AMD's TDP is 28 W, Intel's is 65 W. The sockets are incompatible, with AMD using AMD Socket FP8 and Intel using Intel Socket 1700. AMD's process node is 4 nm fabricated by TSMC; Intel uses 10 nm fabricated by Intel. Intel's die size is 215 mm², while AMD's die size is not recorded.

Cache configurations differ significantly. Both use 80 KB L1 per core and 1 MB versus 1.25 MB L2 per core, but L3 cache diverges sharply: AMD has 4 MB, Intel has 20 MB shared.

Memory support shows AMD accepting DDR5 and LPDDR5X, while Intel accepts DDR4 and DDR5. Both use dual-channel memory buses. AMD records 89.6 GB/s memory bandwidth; Intel's bandwidth is not recorded. PCIe support differs: AMD uses Gen 4 with 14 CPU lanes, Intel uses Gen 5 with 16 CPU lanes. Integrated graphics are Radeon 840M for AMD and UHD Graphics 730 for Intel. Market segments place AMD as Mobile and Intel as Desktop. Release dates differ, with Intel launching in January 2024 and AMD in January 2026. Intel's launch MSRP is $221; AMD has no recorded launch MSRP.

Architecture Differences

AMD's architecture is Zen 5, under the Gorgon Point codename, belonging to the Ryzen AI PRO 400 generation that uses a hybrid of Zen 5 and Zen 5c cores. Intel's architecture is Raptor Lake, under the Raptor Lake-R codename, part of the Core i5 series from the Raptor Lake Refresh generation. These represent fundamentally different design philosophies: AMD's 4 nm TSMC process enables higher density and lower power, while Intel's 10 nm process with a 215 mm² die allows for more physical cores.

The L3 cache difference is the most striking architectural contrast. AMD's 4 MB total L3 versus Intel's 20 MB shared L3 represents a 5x capacity gap. This likely drives Intel's superiority in data compression and random string sorting, workloads that benefit from large working sets residing in cache. AMD's smaller L3 suggests a design optimized for power efficiency and mobile operation rather than raw cache-heavy throughput.

PCIe generation also separates the platforms. Intel's Gen 5 support with 16 lanes provides double the bandwidth per lane compared to AMD's Gen 4 with 14 lanes. This affects expansion options for discrete GPUs and NVMe storage, though the mobile versus desktop market split means these capabilities serve different use cases.

Memory architecture reinforces the platform divide. AMD's dual-channel support for LPDDR5X alongside DDR5 targets power-sensitive mobile designs, while Intel's DDR4 and DDR5 support offers flexibility for desktop builders. AMD's recorded 89.6 GB/s memory bandwidth gives it a defined figure, while Intel's bandwidth remains unrecorded in the database.

The Verdict

The data directs different users toward different processors. Intel's Core i5-14400 is the choice for multi-threaded throughput. Its victories in nine of eleven head-to-head tests, including double-digit leads in every parallel workload, make it the stronger option for rendering, compression, encryption, and physics simulation. The 23.9% multithread advantage and 33.2% floating-point lead are decisive margins that no single-thread result can offset.

AMD's Ryzen AI 5 PRO 435 serves a different profile. Its 28 W TDP compared to Intel's 65 W positions it for laptops and compact systems where thermal and power budgets are constrained. The 0.4% single-thread lead shows competitive per-core performance, and the 86th percentile ranking versus Intel's 82nd suggests strong aggregate standing in the broader database. The mobile market segment and LPDDR5X memory support reinforce this mobile-first design.

The average benchmark scores, 37762 for AMD versus 32115 for Intel, do not align with the head-to-head results. This stems from different benchmark suites in each processor's database entry. Intel's suite includes Cinebench R15, R20, and R23 results along with Geekbench scores, while AMD's entry contains only PassMark tests. Direct comparisons should rely on the shared head-to-head benchmarks, where Intel's dominance is unambiguous.

Users prioritizing raw compute performance on a desktop platform should select Intel. Users requiring a low-power mobile processor with competitive single-thread performance should select AMD. The data does not support a single universal winner; it supports two processors optimized for different segments.
