AMD Ryzen AI 5 PRO 340 vs Intel Core 9 273PTE Comparison

Head-to-Head Benchmarks

The recorded data shows a one-sided contest. The Intel Core 9 273PTE wins 13 of the 15 head-to-head comparisons, with the AMD Ryzen AI 5 PRO 340 taking only the two PassMark single-thread tests. The magnitude of Intel's victories varies widely, from a near-tie in extended instructions to a 43.6% blowout in Cinebench R23 multi-core.

The largest margin belongs to Cinebench R23 multi-core. Intel scores 20445 against AMD's 11534, a delta of -43.6% from AMD's perspective. This is the clearest signal of the core-count and thread-count advantage: Intel fields 12 cores and 24 threads, exactly double AMD's 6 cores and 12 threads. The Cinebench R15 multi-core test tells a similar story but with a smaller gap, 2060 versus 1743, a -15.4% delta. The R23 result amplifies the difference because the workload scales more aggressively with sustained multi-threaded throughput.

Single-core performance is closer but still favors Intel in Cinebench. In Cinebench R15 single-core, Intel leads 290 versus 276, a -4.8% delta. In Cinebench R23 single-core, the gap widens to -37.6%, with Intel at 2886 and AMD at 1802. The R23 single-core result is anomalous relative to R15, suggesting the Intel part scales much better under the longer R23 render loop. The PassMark single-thread tests reverse the trend: AMD leads 3758 versus 3433, a +9.5% delta in AMD's favor. Both PassMark single-thread entries (passmark_single_thread and passmark_singlethread) record identical scores and the same 9.5% margin, confirming the result is consistent across duplicate database entries.

The compute-oriented PassMark tests all favor Intel. Floating point math shows Intel at 60673 versus AMD's 39662, a -34.6% delta. Integer math is closer: 82411 versus 63233, a -23.3% delta. Prime number finding is the most extreme divergence: Intel scores 142, AMD scores 74, a -47.9% delta. This workload is highly sensitive to branch prediction and integer throughput, and the Intel part nearly doubles the AMD score. Extended instructions is the tightest race in the entire set: Intel at 15952, AMD at 15721, a -1.4% delta. The two processors are essentially equivalent on SIMD-heavy code despite their architectural differences.

Memory and data-oriented tests also go to Intel. Data compression shows Intel at 258704 versus 221581, a -14.3% delta. Data encryption shows Intel at 14253 versus 11212, a -21.3% delta. Random string sorting shows Intel at 28973 versus 24334, a -16% delta. These results suggest the Intel part sustains higher throughput on memory-bound and pointer-chasing workloads, likely aided by its larger L3 cache.

The multithread and physics benchmarks continue the pattern. PassMark multithread gives Intel 24054 versus AMD's 19215, a -20.1% delta. PassMark physics gives Intel 1917 versus AMD's 1084, a -43.5% delta. The physics test is notoriously sensitive to thread scheduling and raw core counts, so the near-2x core advantage explains the large margin. Across all 15 benchmarks, Intel's average score is 31143 against AMD's 27932, a difference that places Intel at the 82nd percentile of all CPUs versus AMD's 80th percentile.

Architecture Differences

The two processors come from different design philosophies. AMD uses a 4 nm TSMC process with a Zen 5 architecture under the Krackan Point codename, part of the Ryzen AI PRO 300 generation that mixes Zen 5 and Zen 5c cores. Intel uses a 10 nm process from its own foundry with the Bartlett Lake codename. The die sizes tell part of the story: AMD's die measures 195 mm², while Intel's die size is not recorded in the database.

Core counts differ sharply. AMD provides 6 cores and 12 threads, while Intel provides 12 cores and 24 threads. The base clocks also diverge: AMD runs at 2.00 GHz base and 4.80 GHz boost, while Intel runs at 1.40 GHz base and 5.50 GHz boost. Intel's lower base clock and higher boost clock suggest a design tuned for burst performance under load, while AMD's higher base clock and lower boost clock indicate a more conservative power envelope. The TDP reflects this: AMD is rated at 28 watts, Intel at 45 watts.

Cache hierarchies differ substantially. Both use 80 KB of L1 per core and 1 MB of L2 per core on the AMD side versus 2 MB of L2 per core on the Intel side. The L3 cache is the biggest divergence: AMD has 8 MB total, Intel has 36 MB shared. That 4.5x L3 advantage likely contributes to Intel's wins in data compression, random string sorting, and integer math, where working sets can exceed AMD's smaller L3.

Memory support overlaps on DDR5, but Intel also supports DDR4 while AMD supports LPDDR5X. Both are dual-channel with 89.6 GB/s of memory bandwidth. Both support ECC memory. PCIe connectivity differs by generation: AMD uses Gen 4 with 16 CPU lanes, Intel uses Gen 5 with 16 CPU lanes. Integrated graphics differ as well: AMD pairs with the Radeon 840M, Intel with UHD Graphics 730.

The sockets and market segments reinforce the positioning. AMD uses AMD Socket FP8 and is classified as a mobile part. Intel uses Intel Socket 1700 and is classified as a desktop part. AMD's release date is 2025-01-05, while Intel's is 2026-03-08. Neither processor has an unlocked multiplier. AMD's part number is 100-000001600, Intel's is SA4QJ. Intel carries a launch MSRP of $549; AMD has no recorded launch MSRP.

Where Each One Wins

The Intel Core 9 273PTE wins every multi-threaded and compute-heavy workload in the dataset. Its 13 benchmark victories include all three Cinebench tests, all PassMark math and data tests, and the PassMark multithread and physics tests. The largest margins appear in prime number finding (-47.9%), Cinebench R23 multi-core (-43.6%), and physics (-43.5%). These are workloads that scale with core count, thread count, and large shared caches. For rendering, scientific computation, data compression, encryption, and any task that can use more than 12 threads, the Intel part delivers substantially higher throughput. The 36 MB L3 cache provides a meaningful edge in data-heavy workloads like compression and sorting, where the working set can exceed the AMD part's 8 MB L3.

The AMD Ryzen AI 5 PRO 340 wins exactly two benchmarks: the PassMark single-thread tests. Its score of 3758 beats Intel's 3433 by 9.5%. This indicates the AMD core achieves higher per-thread performance in light, short-duration workloads despite having a lower boost clock of 4.80 GHz versus Intel's 5.50 GHz. The 28-watt TDP also positions it as a lower-power part, which matters for thermally constrained mobile chassis. For single-threaded responsiveness, the AMD part is the stronger performer.

The Verdict

The benchmark data draws a clear line. The Intel Core 9 273PTE is the dominant processor for multi-threaded and data-intensive tasks. It wins 13 of 15 comparisons, holds a 31143 average benchmark score against AMD's 27932, and sits at the 82nd percentile of all CPUs versus AMD's 80th. The 12-core, 24-thread configuration with 36 MB of shared L3 cache delivers leads of 43.6% in Cinebench R23 multi-core, 47.9% in prime number finding, and 43.5% in physics. Anyone selecting a processor for rendering, compilation, data processing, or heavy multitasking should choose the Intel part based on these measurements.

The AMD Ryzen AI 5 PRO 340 is the choice only when single-thread performance is the priority. Its 9.5% lead in PassMark single-thread tests, combined with a 28-watt TDP and mobile socket, makes it suitable for lightweight, power-sensitive systems where responsiveness matters more than raw throughput. The data does not support selecting AMD for any multi-threaded workload. The two processors serve different segments: Intel for desktop compute density, AMD for mobile efficiency with a single-thread edge.
