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

Head-to-Head Benchmarks

The recorded data shows a decisive overall win for the Intel Core 9 273PE, taking 13 of the 15 compared benchmarks. The AMD Ryzen AI 5 PRO 340 manages only two wins, both in the PassMark single-thread tests. In the `passmark_single_thread` and `passmark_singlethread` tests, the AMD scores 3758 against Intel's 3650, a 3% advantage for the AMD part. This is the only category where the AMD processor leads.

Every multi-core and compute-heavy test falls to Intel. The largest gap appears in `cinebench_cinebench_r23_multicore`, where Intel scores 31288 versus AMD's 11534, a delta of -63.1% for the AMD. Similarly, `passmark_floating_point_math` shows Intel at 107884 and AMD at 39662, a -63.2% difference. The `passmark_physics` test shows Intel at 3120 and AMD at 1084, a -65.3% gap, the widest margin in the entire head-to-head set.

The Intel part also dominates in integer and encryption workloads. In `passmark_integer_math`, Intel scores 139410 against AMD's 63233, a -54.6% delta. `passmark_data_encryption` shows Intel at 22719 versus AMD's 11212, a -50.6% difference. `passmark_data_compression` has Intel at 405885 and AMD at 221581, a -45.4% gap. Even in single-core Cinebench tests, Intel leads: `cinebench_cinebench_r15_singlecore` shows Intel at 445 and AMD at 276, a -38% delta, and `cinebench_cinebench_r23_singlecore` shows Intel at 4417 and AMD at 1802, a -59.2% difference.

The only tests where the margin is relatively smaller are the extended instructions and random string sorting. `passmark_extended_instructions` has Intel at 24630 and AMD at 15721, a -36.2% delta. `passmark_random_string_sorting` shows Intel at 45098 and AMD at 24334, a -46% difference. Overall, the average benchmark score for the Intel is 49845, while the AMD sits at 27932. The Intel places in the 90th percentile of all CPUs, while the AMD is in the 80th percentile.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 5 PRO 340 uses the Zen 5 architecture, codenamed Krackan Point, built on a 4 nm process at TSMC. It is part of the Ryzen AI PRO 300 generation, which combines Zen 5 and Zen 5c cores. The Intel Core 9 273PE uses the Bartlett Lake codename, built on a 10 nm process at Intel's own foundry, and belongs to the Core 9 generation.

Core counts differ substantially. The AMD has 6 cores and 12 threads, while the Intel has 12 cores and 24 threads. This doubling of core and thread counts directly explains the large multi-core benchmark gaps. The Intel also has a higher base clock at 2.30 GHz versus AMD's 2.00 GHz, and a higher boost clock at 5.70 GHz versus AMD's 4.80 GHz.

Cache configurations vary greatly. Both have 80 KB of L1 cache per core. The AMD has 1 MB of L2 per core, while the Intel has 2 MB per core. The L3 cache shows the biggest difference: the AMD has 8 MB total, while the Intel has 36 MB shared. This larger cache pool likely contributes to Intel's advantage in data-heavy workloads like compression and encryption.

The memory support differs in type. The AMD supports DDR5 and LPDDR5X, while the Intel supports DDR4 and DDR5. Both have dual-channel memory buses and identical memory bandwidth at 89.6 GB/s. Both support ECC memory. The PCIe generation differs: the AMD uses Gen 4 with 16 lanes from the CPU, while the Intel uses Gen 5 with 16 lanes from the CPU.

Integrated graphics also differ. The AMD uses Radeon 840M, while the Intel uses UHD Graphics 730. The AMD is a mobile segment part with an AMD Socket FP8, while the Intel is a desktop segment part with an Intel Socket 1700. The AMD has a die size of 195 mm², while the Intel's die size is not recorded. The Intel has a 65 TDP, while the AMD has a 28 TDP. The Intel launched in March 2026, while the AMD launched in January 2025.

The Verdict

The benchmark data indicates that the Intel Core 9 273PE is the clear performance leader across nearly all measured categories. Its 12 cores and 24 threads, combined with a 36 MB L3 cache and higher clock speeds, deliver results that are consistently 36% to 65% ahead of the AMD in multi-threaded and compute-intensive workloads. The Intel's 90th percentile ranking versus AMD's 80th percentile confirms this positioning.

The AMD Ryzen AI 5 PRO 340 does hold a small edge in single-thread PassMark tests, with a 3% lead. However, this advantage does not translate to Cinebench single-core tests, where Intel leads by 38% to 59%. The AMD's lower TDP of 28 watts suggests a more power-efficient design, but the database does not include power consumption measurements to confirm this.

For users prioritizing raw computational throughput, the Intel is the obvious choice based on the recorded data. The AMD's strengths appear limited to a narrow single-thread PassMark scenario, which is unlikely to compensate for its substantial deficits in multi-core, encryption, compression, and physics workloads. The Intel's launch MSRP is $549, but the database provides no pricing for the AMD, so no cost comparison is possible.

Where Each One Wins

The Intel Core 9 273PE wins in all multi-core Cinebench tests, all PassMark compute tests, and all data-processing tests. Specifically, it leads in `cinebench_r15_multicore` (3153 vs 1743), `cinebench_r23_multicore` (31288 vs 11534), `passmark_data_compression` (405885 vs 221581), `passmark_data_encryption` (22719 vs 11212), `passmark_extended_instructions` (24630 vs 15721), `passmark_find_prime_numbers` (203 vs 74), `passmark_floating_point_math` (107884 vs 39662), `passmark_integer_math` (139410 vs 63233), `passmark_multithread` (36810 vs 19215), `passmark_physics` (3120 vs 1084), and `passmark_random_string_sorting` (45098 vs 24334). It also wins both Cinebench single-core tests.

The AMD Ryzen AI 5 PRO 340 wins only in the two PassMark single-thread tests, scoring 3758 versus Intel's 3650 in both `passmark_single_thread` and `passmark_singlethread`. This represents a 3% edge, which is relatively small compared to the margins Intel achieves elsewhere.

The data suggests the Intel is suited for workloads requiring maximum multi-threading, such as rendering, physics simulation, encryption, and large data compression tasks. The AMD's narrow single-thread PassMark win could benefit lightly threaded applications that rely on that specific benchmark's behavior, but the Cinebench single-core results contradict this, showing Intel ahead by 38% to 59%. The AMD's lower TDP of 28 watts versus Intel's 65 watts indicates a more power-efficient design, which could favor mobile or thermally constrained environments, though no direct power consumption benchmarks are recorded in the database.
