AMD Ryzen AI 7 445 vs Intel Core 9 273PE Comparison

Head-to-Head Benchmarks

The recorded data shows a comprehensive sweep for the Intel Core 9 273PE across every benchmark in the head-to-head comparison. The Intel part wins all 15 tests, but the margins vary dramatically, ranging from a near-tie in single-threaded workloads to a dominant performance gap in multi-threaded and math-intensive tasks.

The closest contest is in the PassMark single-thread test, where the Intel Core 9 273PE scores 3650 against the AMD Ryzen AI 7 445's 3591, a delta of only 1.6%. This indicates that for lightly threaded applications, the architectural efficiency of the AMD Zen 5 core nearly neutralizes the Intel part's clock advantage. The same pattern appears in the duplicate PassMark single-thread entry, again with a 1.6% gap.

Moving to Cinebench R15 single-core, the Intel part's lead expands to 42.9%, scoring 445 versus 254. The Cinebench R23 single-core test shows a 59.1% advantage for Intel, with scores of 4417 and 1806 respectively. This suggests that the Intel Core 9 273PE's higher boost clock of 5.70 GHz, compared to the AMD part's 4.60 GHz, translates into substantial single-thread performance gains in sustained rendering workloads, even though the synthetic PassMark single-thread test shows a much smaller difference.

The multi-core results are where the Intel part pulls away decisively. In Cinebench R15 multi-core, the Intel Core 9 273PE scores 3153 against 1723 for the AMD, a 45.4% margin. The Cinebench R23 multi-core test shows the largest gap of the entire comparison: Intel scores 31288 versus 10590, a 66.2% deficit for the AMD part. This aligns with the core count disparity, as the Intel chip has 12 cores and 24 threads, double the AMD's 6 cores and 12 threads.

PassMark integer math shows the Intel part delivering 139410 against 58332, a 58.2% advantage. Floating-point math follows a similar trajectory, with Intel at 107884 versus 39362, a 63.5% gap. The physics simulation test shows a 68.7% lead for Intel, scoring 3120 versus 976. The prime number finding test records the most lopsided result, with Intel at 203 versus 56, a 72.4% deficit for the AMD part.

Data-centric workloads also favor Intel heavily. Data compression shows Intel at 405885 versus 215812, a 46.8% margin. Data encryption sees Intel at 22719 versus 10519, a 53.7% gap. Extended instructions (SIMD workloads) show Intel at 24630 versus 15826, a 35.7% advantage, which is the smallest multi-threaded margin in the set. Random string sorting records Intel at 45098 versus 23488, a 47.9% lead.

The overall PassMark multi-thread score puts Intel at 36810 versus 18115, a 50.8% margin. Across all benchmarks, the Intel Core 9 273PE's average benchmark score is 49845, while the AMD Ryzen AI 7 445 averages 26936. This translates to a percentile ranking of 90 for Intel against all CPUs in the database, versus 79 for the AMD part.

The Verdict

The data clearly indicates that the Intel Core 9 273PE is the stronger processor in every measured category. For users who need maximum multi-threaded throughput, rendering performance, or data processing capability, the Intel part is the definitive choice. Its 12 cores and 24 threads, combined with a 5.70 GHz boost clock, deliver a 66.2% advantage in Cinebench R23 multi-core and a 50.8% lead in PassMark multi-thread.

The AMD Ryzen AI 7 445 does close the gap in single-threaded workloads, particularly in the PassMark single-thread test where the difference narrows to just 1.6%. However, even in single-core Cinebench tests, the Intel part maintains a commanding lead, suggesting that the AMD part's Zen 5 architecture cannot fully compensate for the clock speed difference in sustained workloads.

From the database perspective, the Intel Core 9 273PE sits in the 90th percentile of all CPUs, while the AMD part sits in the 79th percentile. The Intel chip's nearest rivals include the AMD Ryzen AI Max+ 388 (0.1% lower average score), the Intel Core i5-14600KF (0.9% lower), and the Intel Core i9-13980HX (1.1% higher). The AMD Ryzen AI 7 445's nearest rivals include the Intel Core i7-1370P (0.1% higher average score), the AMD Ryzen 5 7545U (0.3% higher), and the AMD Ryzen 7 5700G (0.4% lower).

The verdict is straightforward: the Intel Core 9 273PE is the superior processor across the board, with no benchmark where the AMD part gains an advantage. The AMD Ryzen AI 7 445 is a capable mobile chip, but it does not compete head-to-head with the desktop-class Intel part in any measured workload.
