AMD Ryzen AI 7 450 vs Intel Core 9 273PE Comparison

Where Each One Wins

The benchmark data splits cleanly into two distinct profiles. The AMD Ryzen AI 7 450 wins the PassMark single-thread test in both recorded entries, scoring 3901 against the Intel Core 9 273PE's 3650, a 6.9% advantage. That is the only category where AMD holds the lead. The Intel part wins every other recorded benchmark, 13 of 15 head-to-head comparisons, and by margins that range from moderate to overwhelming.

The Intel Core 9 273PE dominates heavily threaded workloads. In Cinebench R23 multi-core, it scores 31288 versus 18316, a 41.5% lead. The gap is even larger in floating-point math, where Intel posts 107884 against AMD's 54447, a 49.5% deficit for the Ryzen part. Prime number finding shows the widest relative gap at 56.2%, with Intel scoring 203 versus 89. Physics simulation follows a similar pattern, Intel at 3120 versus 1578, a 49.4% difference.

The AMD part does hold a narrow single-thread win in PassMark, but the Intel part counters with a much larger single-core win in Cinebench R23, 4417 versus 2038, a 53.9% margin. This discrepancy between the two single-thread tests is notable. The PassMark single-thread result favors AMD by 6.9%, while the Cinebench R23 single-core result favors Intel by more than half. The Intel part also leads in Cinebench R15 single-core, 445 versus 215, a 51.7% gap.

For data-oriented tasks, Intel leads in every recorded PassMark workload. Data compression shows Intel at 405885 versus 315906, a 22.2% margin. Data encryption favors Intel at 22719 versus 16247, a 28.5% gap. Random string sorting goes to Intel at 45098 versus 35648, a 21% advantage. Extended instructions favor Intel by 9.1%, the narrowest Intel win in the entire dataset.

The average benchmark score reflects this overall balance. The Intel part records 49845 against the AMD part's 39485, a difference of roughly 26%. The percentile placement confirms the separation, with Intel at the 90th percentile of all CPUs and AMD at the 87th percentile.

Architecture Differences

The two processors come from different design philosophies and manufacturing processes. The AMD Ryzen AI 7 450 uses the Zen 5 architecture on a 4 nm process from TSMC, with a die size of 195 mm². It belongs to the Ryzen AI 400 generation, codenamed Gorgon Point. The Intel Core 9 273PE uses the Bartlett Lake codename, belongs to the Core 9 generation, and is built on Intel's 10 nm process at Intel's own foundry.

Core counts differ substantially. The AMD part has 8 cores and 16 threads. The Intel part has 12 cores and 24 threads, a 50% advantage in both core count and thread count. The base clock favors Intel at 2.30 GHz versus 2.00 GHz, and the boost clock also favors Intel at 5.70 GHz versus 5.10 GHz.

Cache hierarchies follow different designs. Both parts use 80 KB of L1 cache per core. The L2 cache per core is 1 MB on the AMD part and 2 MB on the Intel part. The L3 cache shows the largest structural difference, with AMD providing 8 MB and Intel providing 36 MB shared. That 28 MB gap is substantial and likely contributes to the Intel part's strong showing in multi-threaded and data-heavy workloads.

Memory support differs in scope. The AMD part supports DDR5 and LPDDR5X. The Intel part supports DDR4 and DDR5. Both use dual-channel memory buses and both record 89.6 GB/s of memory bandwidth. Both support ECC memory.

The platform positioning differs as well. The AMD part uses AMD Socket FP8, targets the mobile market segment, and includes Radeon 860M integrated graphics. The Intel part uses Intel Socket 1700, targets the desktop market segment, and includes UHD Graphics 730. PCIe support moves to Gen 5 on the Intel part with 16 lanes, while the AMD part uses Gen 4 with 16 lanes. The Intel part has a launch MSRP of $549.

The production status for both parts is active. The AMD part carries part number 100-000001868, and the Intel part carries part number SA4QD. Neither part has an unlocked multiplier. The release dates differ, with the AMD part dated 2026-01-04 and the Intel part dated 2026-03-08.

Head-to-Head Benchmarks

The Cinebench R23 single-core test presents the most striking result in the dataset. The Intel Core 9 273PE scores 4417, while the AMD Ryzen AI 7 450 scores 2038. That 53.9% margin is the second-largest gap recorded. The Cinebench R15 single-core test shows a similar pattern, with Intel at 445 versus 215, a 51.7% gap.

The Cinebench R23 multi-core test confirms Intel's advantage scales with thread count. Intel scores 31288 against AMD's 18316, a 41.5% lead. The Cinebench R15 multi-core test narrows the margin to 14%, with Intel at 3153 versus 2713.

PassMark floating-point math shows a near-doubling of performance for Intel. Intel scores 107884, AMD scores 54447, a 49.5% deficit for AMD. Integer math follows with Intel at 139410 versus 88531, a 36.5% gap. Physics simulation shows Intel at 3120 versus 1578, a 49.4% margin.

Prime number finding records the widest relative gap in the entire dataset. Intel scores 203, AMD scores 89, a 56.2% difference. This workload often reflects branch prediction and integer throughput, and the data indicates a decisive Intel advantage.

Data compression favors Intel at 405885 versus 315906, a 22.2% margin. Data encryption shows Intel at 22719 versus 16247, a 28.5% gap. Random string sorting records Intel at 45098 versus 35648, a 21% difference. Extended instructions show the narrowest Intel win at 9.1%, with Intel at 24630 versus 22400.

The PassMark multi-thread test shows Intel at 36810 versus 26350, a 28.4% margin. The AMD part's only wins appear in the PassMark single-thread tests. Both entries, passmark_single_thread and passmark_singlethread, record the same scores: AMD at 3901, Intel at 3650, a 6.9% advantage for AMD.

The aggregate picture is unambiguous. The Intel part holds a substantial lead in nearly every workload category, with particular strength in multi-threaded, floating-point, and memory-sensitive tasks. The AMD part's single-thread PassMark win is real but narrow, and it does not translate to Cinebench single-core results, where Intel leads by more than half. The recorded data places the Intel part at the 90th percentile of all CPUs, three points above the AMD part's 87th percentile.
