AMD Ryzen 9 270 vs AMD Ryzen AI Max+ 388 Comparison

Head-to-Head Benchmarks

The recorded data presents a sharply split picture between these two 8-core, 16-thread mobile processors. The AMD Ryzen 9 270 wins 4 of the 15 head-to-head comparisons, while the AMD Ryzen AI Max+ 388 takes 11. However, the margin distribution matters more than the raw win count. The Ryzen 9 270's victories are decisive in Cinebench rendering, whereas the Ryzen AI Max+ 388's wins are broad but often narrower in compute-heavy integer and floating-point workloads.

The largest single delta belongs to the Ryzen 9 270 in Cinebench R23 single-core. It scores 3,732 against the Ryzen AI Max+ 388's 1,960, a 90.4% advantage. This is the defining gap of the comparison. The Ryzen AI Max+ 388, despite its newer Zen 5 architecture, shows a dramatically lower single-core Cinebench result, which suggests the database's measured configuration underperforms in that specific test. The Ryzen 9 270 also leads Cinebench R23 multi-core by a substantial 40.9% margin, scoring 26,438 versus 18,759. In Cinebench R15 single-core, the Ryzen 9 270 again wins by 26.2% with a score of 376 against 298. Data encryption is the fourth win for the Ryzen 9 270, though by a slim 3.8% margin (20,852 versus 20,092).

The Ryzen AI Max+ 388's wins are led by PassMark physics, where it scores 1,843 against 1,365, a 25.9% advantage. In extended instructions, it leads 32,719 versus 26,729, an 18.3% gap. Floating-point math shows a 17.3% lead (72,722 versus 60,122), and multi-thread performance is 13.1% higher (33,486 versus 29,089). Data compression favors the Ryzen AI Max+ 388 by 12.3% (400,887 versus 351,398). Integer math is 10.3% higher (109,588 versus 98,266), and single-thread PassMark shows a 9.6% lead (4,185 versus 3,784). The smallest margin is in random string sorting, where the Ryzen AI Max+ 388 wins by only 0.9% (43,196 versus 42,819). Prime number finding shows a 39.3% gap in favor of the Ryzen AI Max+ 388 (145 versus 88), a notable outlier in the PassMark suite.

The average benchmark scores reflect this divergence. The Ryzen 9 270 posts an average of 40,246, placing it at the 87th percentile of all CPUs. Its nearest rival, the Intel Core i9-13905H, averages 40,313, a 0.2% gap. The Ryzen AI Max+ 388 averages 49,796, at the 90th percentile. Its nearest rival, the Intel Core 9 273PE, averages 49,845, a 0.1% gap. The 23.7% difference in average score between the two AMD parts is consistent with the Ryzen AI Max+ 388's broad PassMark superiority, but it does not capture the Cinebench anomaly where the Ryzen 9 270 outperforms by a wide margin.

The Verdict

The data supports a clear split based on workload type. The AMD Ryzen 9 270 is the choice for Cinebench-oriented rendering tasks, where its R23 multi-core score of 26,438 is 40.9% above the Ryzen AI Max+ 388. Its R23 single-core score of 3,732 is 90.4% higher, making it the stronger part for lightly threaded rendering workloads as well. The Ryzen 9 270 also wins data encryption by 3.8%, though that margin is modest.

The AMD Ryzen AI Max+ 388 is the more consistent performer across the PassMark suite. It wins 11 of 15 comparisons, including physics, extended instructions, floating-point math, integer math, data compression, and multi-thread tests. Its average benchmark score of 49,796 is 23.7% higher than the Ryzen 9 270's 40,246. For general-purpose compute, memory-sensitive workloads, and PassMark-style mixed tasks, the Ryzen AI Max+ 388 is the stronger part. The one caveat is Cinebench, where the Ryzen 9 270's results are dramatically better, so users whose primary metric is Cinebench should disregard the overall win count.

Specification Differences

The two processors share the same core and thread counts: 8 cores and 16 threads. Both use TSMC's 4 nm process node. The Ryzen 9 270 has a base clock of 4.00 GHz and a boost clock of 5.20 GHz, while the Ryzen AI Max+ 388 has a base clock of 3.60 GHz and a boost clock of 5.00 GHz. The Ryzen 9 270 carries a 45 W TDP; the Ryzen AI Max+ 388 carries a 55 W TDP. They use different sockets: the Ryzen 9 270 fits AMD Socket FP8, while the Ryzen AI Max+ 388 uses AMD Socket FP11.

Memory configurations differ significantly. The Ryzen 9 270 supports DDR5 over a dual-channel bus with 89.6 GB/s of bandwidth. The Ryzen AI Max+ 388 supports LPDDR5X over a quad-channel bus with 256.0 GB/s of bandwidth. ECC memory is not supported on the Ryzen 9 270 but is supported on the Ryzen AI Max+ 388. PCIe lane counts also differ: the Ryzen 9 270 provides 20 Gen 4 lanes (CPU only), while the Ryzen AI Max+ 388 provides 16 Gen 4 lanes. The integrated graphics differ as well, with the Ryzen 9 270 using a Radeon 780M and the Ryzen AI Max+ 388 using a Radeon 8060S. The Ryzen 9 270 was released on 2025-01-05, and the Ryzen AI Max+ 388 on 2026-01-05. Both are active production parts with locked multipliers.

Architecture Differences

The Ryzen 9 270 is built on Zen 4 architecture under the Hawk Point codename, while the Ryzen AI Max+ 388 uses Zen 5 architecture under the Strix Halo codename. The Ryzen 9 270's die size is 178 mm² with 25,000 million transistors. The Ryzen AI Max+ 388 uses a dual-die layout of 2x 70.6 mm², and its transistor count is not recorded in the database.

Cache hierarchies differ in L1 and L3. The Ryzen 9 270 has 64 KB of L1 per core and 16 MB of shared L3. The Ryzen AI Max+ 388 has 80 KB of L1 per core and 32 MB of shared L3. Both have 1 MB of L2 per core. The Ryzen AI Max+ 388's larger L3 and per-core L1, combined with its quad-channel LPDDR5X memory bus, align with its strong PassMark data compression and floating-point results. The Ryzen 9 270's smaller L3 and dual-channel DDR5 bus do not appear to hinder its Cinebench performance, which is likely driven by its higher clock speeds.

Where Each One Wins

The AMD Ryzen 9 270 wins in Cinebench R15 single-core, Cinebench R15 multi-core, Cinebench R23 single-core, Cinebench R23 multi-core, and PassMark data encryption. Its clock advantage (5.20 GHz boost versus 5.00 GHz) and Zen 4 design deliver outsized Cinebench results. The 90.4% lead in R23 single-core is the standout metric, and the 40.9% lead in R23 multi-core confirms that the Ryzen 9 270 is the stronger part for Cinebench-based rendering, both single-threaded and multi-threaded.

The AMD Ryzen AI Max+ 388 wins in PassMark physics, extended instructions, prime number finding, floating-point math, integer math, multi-thread, random string sorting, single-thread, data compression, and both single-thread variants. Its 256.0 GB/s memory bandwidth, 32 MB L3 cache, and Zen 5 architecture produce consistent wins across the PassMark suite. The physics test shows a 25.9% lead, and the floating-point math test shows a 17.3% lead. Prime number finding is the largest relative PassMark win at 39.3%. The Ryzen AI Max+ 388 also holds the higher average benchmark score, 49,796 versus 40,246, and the higher percentile ranking at 90 versus 87. For workloads resembling the PassMark suite, particularly those involving memory bandwidth, encryption, compression, or extended instruction sets, the Ryzen AI Max+ 388 is the stronger processor in the database's measurements.
