AMD Ryzen 7 9700F vs AMD Ryzen AI 9 HX 370 Comparison

AMD Ryzen 7 9700F and AMD Ryzen AI 9 HX 370 represent two distinct interpretations of the Zen 5 architecture, one aimed at desktop performance and the other at mobile efficiency. The recorded data shows a clear split in strengths, with the desktop part dominating single-thread workloads while the mobile chip counters in several multi-threaded and memory-sensitive tests. This analysis examines the benchmark results, architectural choices, and specification differences to determine which processor suits which workload profile.

Head-to-Head Benchmarks

The most decisive victory in the dataset belongs to the AMD Ryzen 7 9700F in the PassMark find prime numbers test. It scores 183 against the HX 370's 126, a 45.2% advantage. This workload is highly dependent on integer instruction throughput and low-latency cache access, both of which favor the desktop chip's higher clock speeds and larger L3 cache. The 9700F also leads in single-thread performance, scoring 4691 versus 3973, a 18.1% margin in both PassMark single-thread variants. This aligns with its 5.50 GHz boost clock compared to the HX 370's 5.10 GHz.

The 9700F extends its lead in the physics test, scoring 2122 against 1881, a 12.8% difference. Physics simulations often scale with both core count and per-core efficiency, and here the desktop chip's higher frequency per core provides the edge. The extended instructions benchmark also favors the 9700F, with a 33688 to 31653 result, a 6.4% win. This test typically measures SIMD and vector processing capabilities, where the desktop chip's full Zen 5 cores with higher boost clocks outperform the mixed Zen 5 and Zen 5c configuration of the mobile part.

The floating point math test shows a narrower gap, with the 9700F at 77955 versus 76892, a 1.4% lead. The multithread benchmark is also a 9700F win, 36470 versus 35148, a 3.8% margin, despite the HX 370 having 12 cores and 24 threads versus 8 cores and 16 threads. This suggests that the desktop chip's higher per-core throughput compensates for its lower core count in this particular workload.

However, the AMD Ryzen AI 9 HX 370 takes four wins. The largest is in random string sorting, scoring 48723 against 45890, a 5.8% advantage. This test is often sensitive to memory bandwidth and cache hierarchy, and the mobile chip's design appears better suited here. Data compression also favors the HX 370, 445719 versus 421988, a 5.3% win. Data encryption follows with 22252 versus 21488, a 3.4% advantage. The integer math test is the closest, with the HX 370 scoring 122933 against 120788, a 1.7% margin.

Where Each One Wins

The AMD Ryzen 7 9700F is the clear choice for single-threaded and lightly threaded applications. Its 18.1% lead in single-thread performance and 12.8% advantage in physics indicate that workloads like legacy software, certain emulation tasks, and interactive applications that rely on one or two fast cores will see a measurable benefit. The 45.2% win in prime number finding also points to integer-heavy single-threaded tasks, such as certain cryptographic hashing or mathematical simulations, being significantly faster on the desktop chip.

The 9700F also wins in multithread, but the margin is modest at 3.8%. This is notable because the HX 370 has 50% more cores and 50% more threads. The desktop chip's higher boost clock and unified Zen 5 core design appear to close the gap that the core count difference would normally create. For users running multithreaded workloads that are not heavily dependent on memory bandwidth, the 9700F should perform comparably or slightly better.

The AMD Ryzen AI 9 HX 370 excels in memory-sensitive and bandwidth-oriented tasks. Its wins in data compression, data encryption, and random string sorting, with margins of 5.3%, 3.4%, and 5.8% respectively, suggest that its memory subsystem, possibly combined with the higher core count for these parallelizable tasks, provides an advantage. The integer math win, though small at 1.7%, also falls into this category. For workloads like database operations, file archiving, or certain types of data processing that move large blocks of data, the HX 370 is the stronger performer.

Architecture Differences

Both processors use the Zen 5 architecture on a 4 nm TSMC process, but they diverge significantly in implementation. The 9700F uses the Granite Ridge codename with 8 full Zen 5 cores, all capable of high clock speeds. The HX 370 uses the Strix Point codename and combines Zen 5 and Zen 5c cores in a 12-core, 24-thread configuration. The Zen 5c cores are denser and more power-efficient but typically clock lower than full Zen 5 cores, which explains the HX 370's lower 2.00 GHz base clock and 5.10 GHz boost clock compared to the 9700F's 3.80 GHz and 5.50 GHz.

The cache hierarchy differs substantially. The 9700F provides 80 KB of L1 and 1 MB of L2 per core, matching the HX 370's per-core amounts, but the L3 cache is double: 32 MB shared versus 16 MB. This larger L3 cache likely contributes to the 9700F's wins in single-thread and physics tests, where more data can reside on-chip. The die size also reflects the design divergence: the 9700F measures 70.6 mm² while the HX 370 is 233 mm², the larger area accommodating the integrated graphics and additional cores.

The socket and platform targets are completely different. The 9700F uses AMD Socket AM5, a desktop platform with Gen 5 PCIe (24 lanes CPU-only) and a 65W TDP. The HX 370 uses AMD Socket FP8, a mobile platform with Gen 4 PCIe (16 lanes CPU-only) and a 28W TDP. The desktop chip supports ECC memory, while the mobile chip does not. The HX 370 includes integrated Radeon 890M graphics, while the 9700F has no integrated graphics, requiring a discrete GPU. The 9700F also has an unlocked multiplier for overclocking, whereas the HX 370's multiplier is locked.

The Verdict

The benchmark data presents a straightforward choice based on platform and workload. The AMD Ryzen 7 9700F is the superior processor for single-threaded and lightly threaded tasks, with an 18.1% single-thread lead and a 12.8% physics advantage. Its larger 32 MB L3 cache and higher 5.50 GHz boost clock give it a significant edge in applications that depend on one or two fast cores. Even in multithread, it manages a 3.8% win over a chip with 50% more cores, showing that its per-core performance is strong enough to offset the core count deficit. The desktop platform also offers Gen 5 PCIe and ECC memory support, making it suitable for workstation tasks that require data integrity.

The AMD Ryzen AI 9 HX 370 is the pick for mobile systems where power efficiency is paramount, given its 28W TDP versus 65W. Its wins in data compression, encryption, and random string sorting, with margins between 3.4% and 5.8%, indicate that it handles data-intensive, memory-bandwidth-bound workloads effectively. The integrated Radeon 890M graphics and support for LPDDR5X memory make it a complete mobile solution, though its CPU performance in single-thread lags by 18.1% and its overall average benchmark score is 37904 versus 69996 for the 9700F, placing it at the 86th percentile compared to the 9700F's 94th percentile.

The core count difference (12 versus 8) does not translate into a multithread victory for the mobile chip, which suggests that the 9700F's higher clocks and full Zen 5 cores are more valuable than the HX 370's additional Zen 5c cores across the recorded PassMark suite. Users requiring maximum per-core speed and desktop platform features should choose the 9700F. Users needing a low-power processor with integrated graphics and competitive data-processing throughput should choose the HX 370. The data does not support a single best processor; the choice depends on the target system and workload mix.
