Architecture Differences

The two processors diverge sharply at the architectural level. The AMD Ryzen AI 5 340 uses the Zen 5 architecture under the Krackan Point codename and belongs to the Ryzen AI 300 generation, which combines Zen 5 and Zen 5c cores. It is fabricated on a 4 nm process at TSMC with a die size of 195 mm². The Intel Core 9 273PTE uses the Bartlett Lake codename with a 10 nm process from Intel's own foundry, and its die size is not recorded in the database.

The core configurations are fundamentally different. The AMD chip offers 6 cores and 12 threads, while the Intel part provides 12 cores and 24 threads, a 2x advantage in both metrics. The cache hierarchy also differs: the AMD chip has 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3 cache. The Intel part matches the L1 at 80 KB per core but doubles L2 to 2 MB per core and expands L3 to 36 MB shared. This larger L3 cache on the Intel side likely contributes to its performance in cache-sensitive workloads.

Platform features further separate the two. The AMD chip uses the AMD Socket FP8 and is classified as a Mobile part with integrated Radeon 840M graphics. The Intel chip uses Intel Socket 1700, targets the Desktop segment, and integrates UHD Graphics 730. The AMD processor supports PCIe Gen 4 with 16 lanes (CPU only), while the Intel part supports PCIe Gen 5 with 16 lanes (CPU only). ECC memory support is exclusive to the Intel chip, which also carries a part number of SA4QJ versus the AMD chip's 100-000001602. Neither processor has an unlocked multiplier.

Where Each One Wins

The AMD Ryzen AI 5 340 establishes its territory in single-threaded integer workloads and extended instruction processing. Its PassMark single-thread score of 3683 beats the Intel part's 3433 by 7.3%, and its PassMark extended instructions score of 16440 tops the Intel part's 15952 by 3.1%. These wins suggest the Zen 5 architecture delivers strong per-core efficiency, which is valuable for lightly threaded applications like legacy software or latency-sensitive tasks that depend on a single fast core.

The Intel Core 9 273PTE dominates in multi-threaded and throughput-oriented scenarios. Its 12-core, 24-thread configuration drives massive leads in Cinebench R23 multi-core (20445 versus 12532, a 38.7% delta), PassMark physics (1917 versus 1095, a 42.9% delta), and PassMark find prime numbers (142 versus 72, a 49.3% delta). The Intel part also wins in floating-point math, integer math, data compression, data encryption, multithread, and random string sorting. For workloads that scale across cores, such as rendering, scientific simulation, or data processing, the Intel chip is the clear performer.

The use-case split is stark. The AMD chip suits mobile or power-constrained environments, given its 28 W TDP and mobile segment classification. The Intel chip, with a 45 W TDP and desktop orientation, fits systems where power consumption is less critical and raw throughput is paramount. The AMD chip's single-thread advantage does not compensate for the Intel part's massive core-count lead in most multi-threaded tests.

Head-to-Head Benchmarks

The head-to-head data reveals a pattern of Intel dominance with a few notable AMD exceptions. The largest Intel win comes in PassMark find prime numbers, where it scores 142 against the AMD chip's 72, a 49.3% advantage. This test heavily rewards core count and integer throughput. PassMark physics shows a similar gap: 1917 for Intel versus 1095 for AMD, a 42.9% delta. Cinebench R23 multi-core gives Intel a 20445 score versus AMD's 12532, a 38.7% lead, and Cinebench R23 single-core shows Intel ahead at 2886 versus 1915.5, a 33.6% delta.

Floating-point math favors Intel by 34.1% (60673 versus 39967), and integer math favors Intel by 23.5% (82411 versus 63078). Data encryption sees Intel lead by 19.5% (14253 versus 11470), and PassMark multithread has Intel ahead by 18.9% (24054 versus 19506). Random string sorting and data compression show Intel wins of 13.8% (28973 versus 24970) and 11.2% (258704 versus 229796), respectively. Cinebench R15 multi-core and single-core both go to Intel, with deltas of 7% (2060 versus 1915) and 16.3% (290 versus 242.6).

The AMD wins are concentrated in two tests. PassMark single-thread sees AMD score 3683 against Intel's 3433, a 7.3% advantage, and the duplicate single-thread entry confirms the same result. PassMark extended instructions goes to AMD by 3.1% (16440 versus 15952). These wins are narrow compared to the Intel leads, which often exceed 20%. The data indicates that while the AMD chip offers superior single-thread performance, the Intel chip's core count and cache capacity produce overwhelming wins in almost every other measured category.

The Verdict

The benchmark data presents a clear choice based on workload and platform requirements. The Intel Core 9 273PTE is the superior processor for multi-threaded performance, winning 12 of 15 head-to-head benchmarks with leads as large as 49.3% in prime number finding and 42.9% in physics simulations. Its 12 cores, 24 threads, and 36 MB L3 cache deliver decisive advantages in Cinebench R23 multi-core, floating-point math, integer math, and data compression. The Intel chip also carries a higher percentile ranking (82 versus 78) and a higher average benchmark score (31143 versus 25981). For desktop users running render workloads, scientific computations, or data-heavy tasks, the Intel part is the data-backed choice.

The AMD Ryzen AI 5 340 wins where single-thread performance matters most. Its PassMark single-thread score of 3683 exceeds the Intel chip's 3433 by 7.3%, and it also leads in extended instructions by 3.1%. The AMD chip's 28 W TDP and mobile segment classification make it suitable for laptops or compact systems where power draw is a constraint. Its 4 nm process and Zen 5 architecture deliver strong per-core efficiency, which explains its single-thread advantage despite having half the core count. The AMD chip's 78th percentile ranking and 25981 average score are respectable for a 6-core mobile part, but they do not match the Intel chip's throughput capabilities.

The recorded data does not support a single universal winner. Instead, it shows two processors designed for different roles. The Intel Core 9 273PTE, with its 45 W TDP and desktop socket, is built for maximum multi-threaded output. The AMD Ryzen AI 5 340, with its mobile socket and lower TDP, targets efficiency and single-thread responsiveness. Both are active production parts with no multiplier unlock, and neither offers a launch MSRP except the Intel chip's $549. The choice between them should follow the workload: multi-threaded desktop tasks favor Intel, while single-threaded or power-sensitive mobile tasks favor AMD.
