The Verdict

The data indicates two distinct usage profiles. The AMD Ryzen 5 7400F is the stronger single-core performer in the database records. Its 54.5% lead in Cinebench R23 single-core and 56.6% lead in PassMark find prime numbers are the defining results. Any workload that depends heavily on single-threaded execution will favor this desktop processor. Its nearest rivals in the database, the Intel Core i5-14600T at 0.1% lower average score and the Intel Core Ultra 7 155H at 0.2% lower, sit essentially at parity with it.

The AMD Ryzen AI 9 HX 375 is the clear multi-threaded winner. Its 34.2% margin in Cinebench R15 multi-core, 39.1% in floating point math, and 38.6% in integer math show a processor built for parallel throughput. The near-tie in Cinebench R23 multi-core, where it leads by only 0.2%, suggests that this particular workload does not fully exploit its architectural advantages. Its nearest rivals, the Intel Core Ultra 5 235 at 0.1% lower and the Intel Core i9-13900HX at 0.1% lower, bracket it closely in average score.

The Ryzen 5 7400F carries an 83rd percentile ranking versus 89th for the Ryzen AI 9 HX 375. The desktop chip has a launch MSRP of $229. The mobile chip has no recorded launch MSRP. For users who prioritize raw single-thread performance and desktop expandability, the Ryzen 5 7400F is the data-backed choice. For users who need maximum multi-threaded throughput in a mobile package, the Ryzen AI 9 HX 375 is the clear pick.

Architecture Differences

The two processors come from different AMD generations and target different market segments. The Ryzen 5 7400F belongs to the 7000 series, uses the Zen 4 architecture under the Raphael codename, and is a desktop part on AMD Socket AM5. The Ryzen AI 9 HX 375 is from the Ryzen AI 300 generation, uses the Zen 5 and Zen 5c hybrid architecture under the Strix Point codename, and is a mobile part on AMD Socket FP8.

Process technology differs by one node step. The Ryzen 5 7400F uses a 5 nm process from TSMC, while the Ryzen AI 9 HX 375 uses a 4 nm process, also from TSMC. The desktop chip integrates 6,570 million transistors on a 71 mm² die. The mobile chip has no transistor count recorded but carries a die size of 233 mm², over three times larger.

Core counts are substantially different. The Ryzen 5 7400F has 6 cores and 12 threads. The Ryzen AI 9 HX 375 doubles that to 12 cores and 24 threads. Clock speeds favor the desktop chip on the base side: 3.70 GHz base and 4.70 GHz boost for the Ryzen 5 7400F, versus 2.00 GHz base and 5.10 GHz boost for the Ryzen AI 9 HX 375. The higher base clock of the desktop part explains part of its single-core advantage, while the higher boost clock of the mobile part does not translate into single-core wins in the data.

Cache hierarchies differ in both per-core and shared allocations. The Ryzen 5 7400F has 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. The Ryzen AI 9 HX 375 has 80 KB of L1 per core, 1 MB of L2 per core, but only 16 MB of shared L3, half the desktop chip's L3 pool. Neither chip has a 3D V-Cache variant recorded.

Memory support overlaps on DDR5 but diverges on the mobile side. Both support dual-channel DDR5. The Ryzen AI 9 HX 375 adds LPDDR5X support. Memory bandwidth is slightly higher on the mobile part at 89.6 GB/s versus 83.2 GB/s. ECC memory is supported only on the Ryzen 5 7400F. PCIe generation and lane counts differ: the desktop chip has Gen 5 with 24 CPU lanes, the mobile chip has Gen 4 with 16 CPU lanes. The Ryzen 5 7400F has no integrated graphics, while the Ryzen AI 9 HX 375 includes the Radeon 890M. The desktop chip has an unlocked multiplier; the mobile chip does not.

Power envelopes reflect their intended platforms. The Ryzen 5 7400F has a 65 TDP, while the Ryzen AI 9 HX 375 has a 28 TDP, a figure consistent with mobile use. The release dates place the desktop chip about six months later, with the Ryzen 5 7400F launching on 2025-01-08 and the Ryzen AI 9 HX 375 on 2024-06-30.

Where Each One Wins

The Ryzen 5 7400F wins in scenarios that hinge on single-threaded execution. The Cinebench R23 single-core result, a 54.5% lead, is the clearest signal. The PassMark find prime numbers result, a 56.6% lead, reinforces that pattern. These two wins, plus the narrow Cinebench R15 single-core victory at 2.7%, define its strengths. Desktop users running lightly threaded applications, legacy software, or workloads that cannot scale across many cores will see the largest benefit from this chip. The unlocked multiplier also allows manual frequency adjustment, a feature the mobile part lacks.

The Ryzen AI 9 HX 375 wins across nearly every parallel workload. The 34.2% advantage in Cinebench R15 multi-core and the 39.1% lead in floating point math are the standout results. Integer math at 38.6% ahead, data compression at 28.4% ahead, and extended instructions at 25.7% ahead all show a chip that scales well with thread count. The PassMark multithread result, 32916 versus 25645, confirms broad multi-thread superiority. The 89th percentile ranking and 46030 average score put it in a higher overall performance tier than the Ryzen 5 7400F, which sits at the 83rd percentile with a 32750 average.

The near-tie in Cinebench R23 multi-core deserves attention. A 0.2% difference means this particular workload does not separate the two processors, despite the mobile chip having twice the cores and threads. This suggests that the Ryzen 5 7400F's higher base clock and larger 32 MB L3 cache can compensate for its core deficit in some multi-threaded tasks. The Ryzen AI 9 HX 375's 28 TDP and mobile socket make it the appropriate choice for portable systems, while the Ryzen 5 7400F's 65 TDP and AM5 socket target desktop builds. The Radeon 890M integrated graphics in the mobile chip eliminates the need for a discrete GPU in basic display tasks, while the desktop chip requires a separate graphics card.
