AMD Ryzen AI 9 HX 375 vs Intel Core 9 273PTE Comparison

Head-to-Head Benchmarks

The benchmark database shows a decisive overall victory for the AMD Ryzen AI 9 HX 375, which wins 12 of the 15 head-to-head comparisons against the Intel Core 9 273PTE. The AMD part's largest margins come in workloads that stress instruction throughput and parallel execution. The PassMark extended instructions test delivers the biggest gap, with AMD scoring 29269 against Intel's 15952, a 83.5% advantage. That result indicates the AMD silicon handles complex SIMD and cryptographic instruction sets far more efficiently. Data compression shows a similar trend: AMD scores 404918 versus 258704, a 56.5% lead, which points to superior branch prediction and cache handling under repetitive memory access patterns.

The Cinebench R15 multicore test is the second-largest win for AMD, with a score of 3334 versus 2060, a 61.8% margin. This is a notably older benchmark, and the gap suggests that the AMD architecture's thread scheduling and core-to-core communication outperform Intel's design in legacy multi-threaded workloads. PassMark integer math also favors AMD heavily: 121754 versus 82411, a 47.7% lead. The same pattern appears in encryption (20802 versus 14253, 45.9% higher) and random string sorting (44552 versus 28973, 53.8% higher). These results collectively indicate that AMD's 12-core, 24-thread configuration extracts more useful work per clock across a broad spectrum of compute tasks.

The Intel Core 9 273PTE does not go winless. Its most significant victory comes in Cinebench R23 single-core, where it posts 2886 against AMD's 1988, a 31.1% advantage. This is a substantial margin and demonstrates that Intel's highest single-thread performance outpaces AMD's Zen 5 core in this specific rendering workload. The Intel chip also wins PassMark find prime numbers (142 versus 122, a 14.1% lead) and PassMark physics (1917 versus 1819, a 5.1% lead). The prime number test is heavily dependent on integer division and branch prediction, while the physics test rewards raw frequency in lightly threaded simulation loops. These two wins, combined with the R23 single-core result, suggest that Intel retains an edge in certain latency-sensitive, low-thread-count tasks.

The remaining benchmarks split more closely. Cinebench R23 multicore shows AMD ahead by 6.7% (21812 versus 20445), which is a much narrower margin than the R15 result. This implies that as modern rendering workloads scale to all cores, the Intel chip closes the gap significantly. PassMark floating point math gives AMD a 23.9% lead (75153 versus 60673), while PassMark multithread shows AMD ahead by 36.8% (32916 versus 24054). The single-thread PassMark tests favor AMD by 12.6% (3867 versus 3433), which is surprising given Intel's Cinebench R23 single-core win, but the two tests measure different instruction mixes and memory latencies.

Where Each One Wins

The AMD Ryzen AI 9 HX 375 establishes its dominance in throughput-oriented workloads. The database shows consistent wins across data compression, encryption, extended instructions, integer math, multithread, random string sorting, floating point math, and both Cinebench R15 tests. This profile fits content creation, database processing, scientific computing, and virtualization scenarios where all cores are kept busy. The 61.8% lead in Cinebench R15 multicore and the 56.5% lead in data compression are particularly strong indicators for legacy software that does not scale perfectly to many threads but still benefits from high aggregate throughput. The 83.5% margin in extended instructions suggests AMD is the better choice for AVX-heavy code, cryptography, and signal processing.

The Intel Core 9 273PTE's three wins carve out a narrower but distinct niche. The 31.1% advantage in Cinebench R23 single-core is the headline result. This benchmark is widely used for comparing single-thread rendering performance, and a 31.1% gap is large enough to matter for applications that are primarily single-threaded, such as older CAD tools, certain audio plugins, and legacy game engines. The PassMark physics win (5.1% ahead) reinforces this pattern, as physics simulations in games and engineering software often run on one or two threads with heavy floating-point math. The prime number test win (14.1% ahead) is more niche, but it indicates that Intel's integer division unit handles modulo operations more efficiently, which could benefit number-theoretic computations and hash functions.

For users who need a balance, the AMD part's 12.6% lead in PassMark single-thread is relevant. That result suggests that even in single-threaded scenarios, the AMD chip is often faster than Intel, and the Cinebench R23 result may be an outlier driven by that specific workload's instruction mix. The data overall shows that AMD wins the majority of single-thread tests (PassMark single-thread and Cinebench R15 single-core), while Intel wins one high-profile single-thread test (Cinebench R23) and two specialized integer tests.

Specification Differences

The two processors share the same core count (12) and thread count (24), but nearly every other specification diverges. The AMD Ryzen AI 9 HX 375 has a base clock of 2.00 GHz and a boost clock of 5.10 GHz, while the Intel Core 9 273PTE runs at a lower 1.40 GHz base but a higher 5.50 GHz boost. Thermal design power differs substantially: AMD is rated at 28 W, Intel at 45 W. The socket types are incompatible: AMD uses Socket FP8, Intel uses Socket 1700.

Memory support differs in both type and ECC capability. AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. AMD does not support ECC memory, but Intel does. Both use a dual-channel memory bus with identical memory bandwidth of 89.6 GB/s. PCIe generation differs: AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only). The integrated graphics are different, with AMD using the Radeon 890M and Intel using the UHD Graphics 730.

The release dates are notably separated. AMD launched on 2024-06-30, while Intel's release date is 2026-03-08. The Intel part has a launch MSRP of $549. The AMD part has no recorded launch MSRP. The market segments also differ: AMD is classified as a mobile processor, while Intel is classified as desktop. Both are production active and both have locked multipliers.

Architecture Differences

The architectural split is fundamental. AMD's Ryzen AI 9 HX 375 uses the Zen 5 architecture from the Strix Point codename, belonging to the Ryzen AI 300 generation (Zen 5 / Zen 5c). Intel's Core 9 273PTE uses the Bartlett Lake codename from the Core 9 (Bartlett Lake) generation. The manufacturing process differs by node and foundry: AMD is built on a 4 nm process at TSMC, while Intel uses a 10 nm process at Intel.

Cache layouts are similar at the L1 level, with both providing 80 KB per core. The L2 cache differs: AMD provides 1 MB per core, while Intel provides 2 MB per core. The L3 cache is a major distinction: AMD has 16 MB, while Intel has 36 MB (shared). This gives Intel more than double the L3 capacity, which can improve hit rates for large working sets. The die size is recorded for AMD at 233 mm², while Intel's die size is not recorded.

The integrated graphics architectures are entirely different. AMD's Radeon 890M is a modern RDNA-based iGPU designed for mobile use, while Intel's UHD Graphics 730 is a more basic implementation typical of desktop processors. The PCIe generation gap (Gen 4 versus Gen 5) also reflects the platform eras: AMD's mobile socket uses the older standard, while Intel's desktop socket supports the newer one. ECC support on Intel, combined with DDR4 compatibility, positions the Intel part for workstation and server-adjacent use cases, while AMD's LPDDR5X support and lower TDP target thin-and-light laptops. The 45 W TDP on Intel versus 28 W on AMD indicates different power envelopes, though the actual power draw in workloads depends on boost behavior, which the recorded data does not specify.
