Head-to-Head Benchmarks

The head-to-head data shows a consistent pattern. The Ryzen 9 PRO 8945HS wins every recorded comparison, but the margins vary widely by workload type.

The largest win comes in Cinebench R23 multi-core. The Ryzen 9 PRO 8945HS scores 25,165, while the Ryzen AI 7 345 scores 11,461. The delta is 119.6%. This is a more than doubling of performance, and it reflects the combination of more cores, higher clocks, and a larger shared L3 cache. The Ryzen 9 PRO 8945HS also wins Cinebench R15 multi-core by 48.1%, scoring 2,536 against 1,712.

Cinebench R23 single-core shows a 95.4% advantage for the Ryzen 9 PRO 8945HS, with scores of 3,552 and 1,818. Cinebench R15 single-core shows a 31.7% advantage, with scores of 357 and 271. These are notable margins, though the PassMark single-thread result tells a different story. There, the Ryzen 9 PRO 8945HS scores 3,920 and the Ryzen AI 7 345 scores 3,875, a margin of only 1.2%. The discrepancy between Cinebench and PassMark single-thread results suggests workload-specific behavior in the newer Krackan Point design.

PassMark data encryption shows one of the larger gaps. The Ryzen 9 PRO 8945HS scores 21,820, while the Ryzen AI 7 345 scores 11,814, a delta of 84.7%. Random string sorting shows a 75.6% advantage, with scores of 44,668 and 25,435. Extended instructions show a 63% advantage, with scores of 27,714 and 17,003. Integer math shows a 62.9% advantage, with scores of 103,390 and 63,475. Data compression shows a 55.3% advantage, with scores of 368,884 and 237,484. Multi-thread shows a 52.4% advantage, with scores of 30,378 and 19,927. Floating-point math shows a 49% advantage, with scores of 63,490 and 42,621. Find prime numbers shows a 46.8% advantage, with scores of 91 and 62. Physics shows a 31.3% advantage, with scores of 1,430 and 1,089.

The pattern is clear. Across compute-heavy, multi-threaded, and data-intensive workloads, the Ryzen 9 PRO 8945HS holds a commanding lead. The Ryzen AI 7 345 only approaches parity in the narrow single-thread PassMark test, and even there it falls short. The database records 15 wins for the Ryzen 9 PRO 8945HS and 0 wins for the Ryzen AI 7 345.

Specification Differences

The two processors differ in several key specification fields. The Ryzen 9 PRO 8945HS uses 8 cores and 16 threads, while the Ryzen AI 7 345 uses 6 cores and 12 threads.

The Ryzen 9 PRO 8945HS supports DDR5, while the Ryzen AI 7 345 supports both DDR5 and LPDDR5X. Both use a dual-channel memory bus, and both list a memory bandwidth of 89.6 GB/s. ECC memory support is present on the Ryzen 9 PRO 8945HS but absent on the Ryzen AI 7 345.

PCIe lane counts differ. The Ryzen 9 PRO 8945HS provides Gen 4 with 20 lanes (CPU only), while the Ryzen AI 7 345 provides Gen 4 with 14 lanes (CPU only). Integrated graphics differ as well. The Ryzen 9 PRO 8945HS uses the Radeon 780M, while the Ryzen AI 7 345 uses the Radeon 840M. The Ryzen 9 PRO 8945HS is marked as part of the 8000 series, while the Ryzen AI 7 345 has no series designation in the database. The Ryzen 9 PRO 8945HS has part numbers 100-000001314 (FP7r2) and 100-000001386 (FP7), while the Ryzen AI 7 345 has part number 100-000002122. Neither processor has a multiplier unlocked. Both are listed as Active in production status and target the mobile market segment.

Architecture Differences

The architectural split between these two processors is significant. The Ryzen 9 PRO 8945HS uses Zen 4 architecture under the Hawk Point codename, belonging to the Ryzen 9 generation. The Ryzen AI 7 345 uses a Zen 5 and Zen 5c hybrid configuration under the Krackan Point codename, belonging to the Ryzen AI 300 generation. Both are manufactured on a 4 nm process at TSMC. The Ryzen 9 PRO 8945HS lists a transistor count of 25,000 million and a die size of 178 mm². The Ryzen AI 7 345 does not list transistor count or die size in the database.

Cache structures differ notably. The Ryzen 9 PRO 8945HS has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Ryzen AI 7 345 has 80 KB of L1 per core, 1 MB of L2 per core, and only 4 MB of L3. The larger shared L3 on the Ryzen 9 PRO 8945HS is a major factor in its multi-threaded dominance. The Ryzen AI 7 345 compensates slightly with a larger per-core L1, but the total cache pool is much smaller.

The Ryzen 9 PRO 8945HS was released on April 15, 2024. The Ryzen AI 7 345 was released on January 14, 2025. The newer release date for the Ryzen AI 7 345 aligns with its newer Zen 5 and Zen 5c core design, but the benchmark data shows that architectural generation alone does not overcome the raw core count, clock speed, and cache advantages of the Ryzen 9 PRO 8945HS.

The Radeon 780M integrated graphics on the Ryzen 9 PRO 8945HS and the Radeon 840M on the Ryzen AI 7 345 represent different iGPU generations, though the database does not include graphics benchmarks for either processor. The Ryzen 9 PRO 8945HS supports ECC memory, which the Ryzen AI 7 345 does not. The PCIe configurations also differ, with 20 lanes on the Ryzen 9 PRO 8945HS and 14 lanes on the Ryzen AI 7 345, both on Gen 4.

The Verdict

The data points to a clear separation in intended use cases. The Ryzen 9 PRO 8945HS is the stronger processor for multi-threaded, compute-heavy, and data-intensive workloads. Its 8 cores, 16 threads, 5.20 GHz boost clock, 16 MB L3 cache, and 45-watt TDP combine to produce benchmark results that are often 50% to 120% ahead of the Ryzen AI 7 345. For tasks like video encoding, 3D rendering, data compression, encryption, and scientific computing, the Ryzen 9 PRO 8945HS is the one that delivers.

The Ryzen AI 7 345 is not without merit. Its single-thread PassMark score sits within 1.2% of the Ryzen 9 PRO 8945HS. Its 28-watt TDP suggests lower power draw, and its support for LPDDR5X memory and newer Radeon 840M integrated graphics point to a design focused on efficiency and mobility. For lighter workloads where single-thread responsiveness matters most, the gap between the two processors is nearly negligible.

The percentile rankings reinforce this. The Ryzen 9 PRO 8945HS at the 88th percentile is positioned among higher-performing desktop and mobile parts. The Ryzen AI 7 345 at the 81st percentile is still a strong performer, but it sits further down the distribution. Its nearest rivals include the AMD Ryzen 7 3800X, a desktop processor from an older generation, and the Intel Core i5-13500HX, both of which bracket its average score.

The choice between these two processors depends on workload priority. For users who need maximum multi-threaded throughput and are willing to accept a 45-watt TDP, the Ryzen 9 PRO 8945HS is the data-backed selection. For users who prioritize efficiency, newer memory support, and a compact Krackan Point design, the Ryzen AI 7 345 offers competitive single-thread performance while giving up significant ground in multi-threaded tasks. The benchmark record is unambiguous: 15 wins for the Ryzen 9 PRO 8945HS, 0 for the Ryzen AI 7 345.
