Where Each One Wins

The AMD Ryzen AI Max PRO 390 dominates the head-to-head benchmark set with 14 wins out of 15 recorded tests. Its largest advantages appear in multi-threaded and compute-heavy workloads. The processor leads by 90.2% in Cinebench R15 multi-core, 21.4% in Cinebench R23 multi-core, and 78.4% in PassMark multi-thread. Data compression shows a 95.7% lead, integer math is 80.2% ahead, and extended instructions deliver a 156.3% advantage. The AMD part also wins single-thread PassMark tests with a 15.6% lead, indicating that its per-core performance is broadly competitive even where the Intel chip posts its best results.

The Intel Core 9 273PTE takes a single win in Cinebench R23 single-core, with a score of 2886 against 1976 for the AMD part. That is a 31.5% advantage, and it is the only test where the Intel processor exceeds the AMD processor by a significant margin. The Intel chip also has a higher boost clock, 5.50 GHz versus 5.00 GHz, which aligns with its single-core result. However, this advantage does not translate into wins elsewhere. In Cinebench R15 single-core, the AMD part is 4.5% ahead, and in PassMark single-thread the AMD part is 15.6% ahead.

The benchmark pattern indicates that the AMD processor delivers substantially stronger throughput in parallel workloads, while the Intel processor offers a narrower but real lead in one specific single-threaded rendering test. The AMD part also wins the more modern Cinebench R23 multi-core test by 21.4%, suggesting that its advantage scales across generations of the Cinebench workload.

Architecture Differences

The AMD Ryzen AI Max PRO 390 uses the Zen 5 architecture under the Strix Halo codename. It is fabricated on a 4 nm process at TSMC. The Intel Core 9 273PTE uses the Bartlett Lake codename and is built on a 10 nm process at Intel. These process differences contribute to the power and performance profiles of the two chips.

The AMD processor includes 80 KB of L1 cache per core and 1 MB of L2 cache per core. The Intel processor has 80 KB of L1 cache per core and 2 MB of L2 cache per core.

Head-to-Head Benchmarks

The largest single win for the AMD Ryzen AI Max PRO 390 comes in PassMark extended instructions, where it scores 40888 against 15952 for the Intel Core 9 273PTE, a 156.3% lead. This test measures the throughput of advanced instruction sets, and the result indicates a major advantage in workloads that use those instructions.

In PassMark find prime numbers, the AMD part scores 323 versus 142, a 127.5% lead. Data compression shows a 95.7% advantage, with scores of 506170 and 258704. Random string sorting follows closely at 90.7% ahead, with scores of 55248 and 28973. Cinebench R15 multi-core shows a 90.2% lead, with scores of 3918 and 2060.

Data encryption favors the AMD part by 82.6%, with scores of 26027 and 14253. Integer math is 80.2% ahead, with scores of 148508 and 82411. PassMark multi-thread shows a 78.4% lead, with scores of 42912 and 24054. Floating point math is 56% ahead, with scores of 94666 and 60673. PassMark physics shows a 44.7% lead, with scores of 2773 and 1917.

Cinebench R23 multi-core gives the AMD part a 21.4% lead, with scores of 24828 and 20445. PassMark single-thread shows a 15.6% lead, with scores of 3967 and 3433. Cinebench R15 single-core is the closest result, with the AMD part ahead by only 4.5%, scores of 303 and 290.

The Intel Core 9 273PTE wins Cinebench R23 single-core with a score of 2886 against 1976 for the AMD part, a 31.5% advantage. This is the only test where the Intel processor leads, and the margin is substantial. However, the AMD part counters with a 15.6% lead in PassMark single-thread and a 4.5% lead in Cinebench R15 single-core, showing that the Intel single-core win is specific to that benchmark rather than a general property of the chip.

The overall picture from the recorded data is clear: the AMD Ryzen AI Max PRO 390 is the stronger processor in nearly every measured workload, with particularly large margins in compression, encryption, extended instructions, and multi-threaded rendering. The Intel Core 9 273PTE has one notable single-core rendering advantage but trails across the broader benchmark set.
