AMD Ryzen 9 270 vs AMD Ryzen AI 9 HX 375 Comparison

Head-to-Head Benchmarks

The benchmark data presents a sharply divided picture between these two AMD mobile processors. The AMD Ryzen 9 270 wins 4 of the 15 recorded head-to-head tests, while the AMD Ryzen AI 9 HX 375 wins 11. The largest single victory belongs to the Ryzen 9 270 in Cinebench R23 single-core, where it scores 3732 against 1988 for the Ryzen AI 9 HX 375, a delta of 87.7%. That is a decisive margin, suggesting the Zen 4 architecture in the Ryzen 9 270 has a substantial per-thread advantage in this workload.

The Ryzen 9 270 also takes Cinebench R23 multi-core with 26438 points versus 21812, a 21.2% lead. This result is curious because the Ryzen AI 9 HX 375 has 12 cores and 24 threads, compared to 8 cores and 16 threads for the Ryzen 9 270. Despite fewer threads, the Ryzen 9 270 outruns its rival in this rendering test. Cinebench R15 multi-core tells the opposite story: the Ryzen AI 9 HX 375 scores 3334 against 2664, a 20.1% advantage. The two Cinebench versions disagree on which processor is faster in multi-threaded rendering, which points to differences in how each workload scales with core count versus clock speed.

Single-core results outside Cinebench are much closer. In PassMark single-thread, the Ryzen AI 9 HX 375 edges ahead with 3867 versus 3784, a 2.1% margin. Cinebench R15 single-core shows the Ryzen 9 270 ahead by 24.9% (376 versus 301), but Cinebench R23 single-core shows an even larger 87.7% gap. The discrepancy between PassMark and Cinebench single-core scores is striking, indicating that the Ryzen 9 270's higher boost clock of 5.20 GHz helps in certain workloads while the Ryzen AI 9 HX 375's Zen 5 cores hold their own in others.

In PassMark math and data workloads, the Ryzen AI 9 HX 375 dominates consistently. It leads in integer math by 19.3% (121754 versus 98266), floating-point math by 20% (75153 versus 60122), and find prime numbers by 27.9% (122 versus 88). Data compression shows a 13.2% lead for the Ryzen AI 9 HX 375 (404918 versus 351398), while extended instructions favor it by 8.7% (29269 versus 26729). The Ryzen AI 9 HX 375 also wins PassMark multi-thread by 11.6% (32916 versus 29089) and physics by 25% (1819 versus 1365). Random string sorting is close, with the Ryzen AI 9 HX 375 ahead by only 3.9% (44552 versus 42819). Data encryption is nearly identical: the Ryzen 9 270 wins by 0.2% (20852 versus 20802), a margin that is effectively a tie.

The overall average benchmark score reflects this split: the Ryzen AI 9 HX 375 averages 46030, while the Ryzen 9 270 averages 40246. That is a 14.4% difference in aggregate performance. The percentile rankings also separate them: the Ryzen AI 9 HX 375 sits at the 89th percentile of all CPUs in the database, while the Ryzen 9 270 sits at the 87th. Both are strong mobile processors, but the data consistently favors the 12-core part in throughput-oriented tests.

Architecture Differences

The two processors come from different generations and architectures. The AMD Ryzen 9 270 uses Zen 4 with the Hawk Point codename, while the AMD Ryzen AI 9 HX 375 uses Zen 5 with the Strix Point codename. Both are built on TSMC's 4 nm process node, so the manufacturing technology is identical. The die size differs: the Ryzen 9 270 measures 178 mm², while the Ryzen AI 9 HX 375 is larger at 233 mm². The Ryzen 9 270 lists 25,000 million transistors, while the Ryzen AI 9 HX 375 does not have a recorded transistor count in the database.

Core configurations diverge significantly. The Ryzen 9 270 has 8 cores and 16 threads, all presumably based on the Zen 4 architecture. The Ryzen AI 9 HX 375 has 12 cores and 24 threads, and its generation label indicates a hybrid arrangement: "Zen 5 / Zen 5c". This suggests a mix of full-performance and compact cores, which helps explain its higher core count within a similar power envelope. The Ryzen 9 270 has a base clock of 4.00 GHz and a boost clock of 5.20 GHz. The Ryzen AI 9 HX 375 has a much lower base clock of 2.00 GHz but a boost clock of 5.10 GHz, nearly matching the Ryzen 9 270.

Cache layouts differ per core. The Ryzen 9 270 provides 64 KB of L1 per core and 1 MB of L2 per core, with 16 MB of shared L3. The Ryzen AI 9 HX 375 provides 80 KB of L1 per core and 1 MB of L2 per core, also with 16 MB of L3. The larger L1 per core on the Zen 5 part may contribute to its single-thread PassMark lead despite the lower base clock.

Memory support shows one difference: the Ryzen 9 270 supports DDR5 only, while the Ryzen AI 9 HX 375 supports DDR5 and LPDDR5X. Both use a dual-channel memory bus with 89.6 GB/s bandwidth. Neither supports ECC memory. PCIe connectivity differs: the Ryzen 9 270 has Gen 4 with 20 lanes (CPU only), while the Ryzen AI 9 HX 375 has Gen 4 with 16 lanes (CPU only). The integrated graphics also differ, with the Ryzen 9 270 using Radeon 780M and the Ryzen AI 9 HX 375 using Radeon 890M.

Both processors use the same AMD Socket FP8, are locked (multiplier unlocked: false), and target the mobile market segment. The Ryzen 9 270 was released on 2025-01-05, while the Ryzen AI 9 HX 375 came later on 2024-06-30. Neither has a recorded launch MSRP in the database. The Ryzen 9 270's part number is 100-000001836, and the Ryzen AI 9 HX 375's is 100-000001682.

The Verdict

The recorded data indicates a clear split in workload preference. The AMD Ryzen AI 9 HX 375 wins 11 of 15 head-to-head benchmarks, including all PassMark math, compression, and multi-thread tests. Its 12 cores and 24 threads deliver higher throughput in integer math, floating-point math, prime number finding, and physics simulations. The average benchmark score of 46030 versus 40246 reinforces this advantage. For users running heavily parallel workloads, the Ryzen AI 9 HX 375 is the stronger choice based on the data.

The AMD Ryzen 9 270, however, wins the most important single-thread test in the database: Cinebench R23 single-core, with an 87.7% margin. It also wins Cinebench R23 multi-core by 21.2%, despite having fewer cores. The Ryzen 9 270's higher base and boost clocks (4.00 GHz and 5.20 GHz versus 2.00 GHz and 5.10 GHz) appear to give it an edge in lightly threaded or clock-sensitive workloads. Its 8-core design also draws 45 W TDP versus 28 W for the Ryzen AI 9 HX 375, which suggests the Ryzen 9 270 uses more power to achieve those clock speeds.

The percentile ranking favors the Ryzen AI 9 HX 375 (89th versus 87th), and its nearest rivals include the Intel Core Ultra 5 235 and Intel Core i9-13900HX, with delta percentages of -0.1% and -0.1% respectively. The Ryzen 9 270's nearest rivals include the Intel Core i9-13905H and AMD Ryzen 7 7700, with deltas of -0.2% and 0.4%.

Where Each One Wins

The AMD Ryzen AI 9 HX 375 wins in all PassMark tests except data encryption, where the Ryzen 9 270 edges it by 0.2%. The Ryzen AI 9 HX 375 leads in data compression (404918 versus 351398), extended instructions (29269 versus 26729), find prime numbers (122 versus 88), floating-point math (75153 versus 60122), integer math (121754 versus 98266), multi-thread (32916 versus 29089), physics (1819 versus 1365), random string sorting (44552 versus 42819), and single-thread (3867 versus 3784). It also wins Cinebench R15 multi-core (3334 versus 2664). This makes it the clear choice for compute-heavy tasks like data processing, scientific calculations, and any workload that scales across many threads.

The AMD Ryzen 9 270 wins Cinebench R15 single-core (376 versus 301), Cinebench R23 single-core (3732 versus 1988), Cinebench R23 multi-core (26438 versus 21812), and PassMark data encryption (20852 versus 20802). The single-core Cinebench wins are substantial, particularly the 87.7% margin in R23. The multi-core R23 win is notable because it contradicts the core-count advantage of the Ryzen AI 9 HX 375. Users prioritizing software that responds to high clock speeds, such as certain rendering engines or single-threaded applications, would favor the Ryzen 9 270 based on these results.

The win distribution is not uniform. The Ryzen AI 9 HX 375's PassMark dominance suggests a broad advantage in general-purpose integer and floating-point workloads. The Ryzen 9 270's Cinebench wins suggest a specific strength in rendering tasks, possibly due to its higher boost clock. The data does not show a clear winner for all scenarios; instead, it indicates that the 12-core Zen 5 part excels in parallel math and data workloads, while the 8-core Zen 4 part excels in clock-sensitive single-thread and certain multi-thread rendering tests.
