AMD Ryzen 9 PRO 8945HS vs AMD Ryzen AI 5 430 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep. The AMD Ryzen 9 PRO 8945HS wins all 15 benchmark comparisons, with margins ranging from modest to massive. The largest gap appears in Cinebench R23 multi-core, where the Ryzen 9 PRO 8945HS scores 25,165 against the Ryzen AI 5 430's 8,130, a 209.5% advantage. This is not a close contest by any measure.

Single-thread performance tells a more nuanced story. In Cinebench R23 single-core, the Ryzen 9 PRO 8945HS posts 3,552 versus 1,797 for the Ryzen AI 5 430, a 97.7% lead. However, in PassMark's single-thread test, the gap narrows dramatically: 3,920 versus 3,683, a delta of just 6.4%. This suggests the newer architecture in the Ryzen AI 5 430 partially compensates for its lower clock speeds in certain workloads, though not enough to overtake the older chip.

The Cinebench R15 results follow the same pattern. Multi-core shows 2,536 versus 1,195, a 112.2% lead for the Ryzen 9 PRO 8945HS. Single-core shows 357 versus 269, a 32.7% advantage. The multi-core gaps are consistently larger than single-core gaps across all Cinebench versions, which aligns with the core count difference: 8 cores versus 4 cores.

PassMark's specialized workloads amplify the multi-core disparity further. Data encryption shows the largest percentage gap of all tests: 21,820 versus 7,591, a 187.4% lead. Integer math follows closely at 103,390 versus 39,637, a 160.8% advantage. Random string sorting shows 44,668 versus 16,623, a 168.7% gap. These are compute-bound tasks that scale heavily with core count and thread count.

Floating point math shows 63,490 versus 27,193, a 133.5% lead. Extended instructions show 27,714 versus 11,455, a 141.9% gap. Data compression shows 368,884 versus 158,912, a 132.1% lead. Prime number finding shows 91 versus 44, a 106.8% gap. Physics simulation shows 1,430 versus 726, a 97% lead. Multi-threaded PassMark shows 30,378 versus 13,320, a 128.1% gap.

The average benchmark score reflects this dominance. The Ryzen 9 PRO 8945HS averages 41,963 across all tests, placing it in the 88th percentile of all CPUs. The Ryzen AI 5 430 averages 19,617, placing it in the 73rd percentile. The Ryzen 9 PRO 8945HS sits slightly above the Intel Core i7-14700T (41,914, delta 0.1%) and slightly below the AMD Ryzen 5 7400 (42,055, delta -0.2%). The Ryzen AI 5 430 sits just above the AMD Ryzen 5 5500 (19,593, delta 0.1%) and just below the Intel Core i5-12500 (19,668, delta -0.3%).

Architecture Differences

The two processors come from different design generations. The Ryzen 9 PRO 8945HS belongs to the 8000 series, using Zen 4 architecture under the Hawk Point codename. It is part of the Ryzen 9 generation, specifically Zen 4 (Hawk Point). The Ryzen AI 5 430 belongs to the Ryzen AI 400 generation, using Zen 5 / Zen 5c architecture under the Gorgon Point codename. This architectural gap explains why the newer chip, despite having half the cores, manages to stay competitive in single-threaded PassMark tests.

Both chips use a 4 nm process from TSMC. The Ryzen 9 PRO 8945HS lists 25,000 million transistors on a 178 mm² die. The Ryzen AI 5 430 does not list transistor count or die size in the database. The Ryzen 9 PRO 8945HS uses AMD Socket FP7, while the Ryzen AI 5 430 uses AMD Socket FP8. These are not interchangeable sockets.

Core configuration differs sharply. The Ryzen 9 PRO 8945HS offers 8 cores and 16 threads, with a base clock of 4.00 GHz and a boost clock of 5.20 GHz. The Ryzen AI 5 430 offers 4 cores and 8 threads, with a base clock of 2.00 GHz and a boost clock of 4.50 GHz. The older chip has both a higher base and higher boost clock, giving it an advantage in both lightly and heavily threaded workloads.

Cache hierarchy also differs. The Ryzen 9 PRO 8945HS has 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The Ryzen AI 5 430 has 80 KB L1 per core, 1 MB L2 per core, and only 4 MB L3. The larger shared L3 cache on the Ryzen 9 PRO 8945HS likely contributes to its strong performance in data compression and encryption workloads.

Memory support shows similarities and differences. Both chips support DDR5 and dual-channel memory, with identical memory bandwidth of 89.6 GB/s. However, the Ryzen AI 5 430 adds LPDDR5X support, which the Ryzen 9 PRO 8945HS does not list. Both support ECC memory.

PCIe lanes differ. The Ryzen 9 PRO 8945HS provides Gen 4 with 20 lanes (CPU only), while the Ryzen AI 5 430 provides Gen 4 with 14 lanes (CPU only). The integrated graphics also differ: the Ryzen 9 PRO 8945HS uses Radeon 780M, while the Ryzen AI 5 430 uses Radeon 840M.

Release dates show the newer chip arrived later. The Ryzen 9 PRO 8945HS released on 2024-04-15, while the Ryzen AI 5 430 released on 2026-01-04. Both remain in active production. Neither chip has a recorded launch MSRP, and neither has an unlocked multiplier.

Where Each One Wins

The Ryzen 9 PRO 8945HS wins every recorded benchmark, so the use-case split is based on the degree of advantage rather than any reversal. The largest wins appear in multi-threaded, compute-heavy workloads. Data encryption shows a 187.4% lead, integer math shows 160.8%, and random string sorting shows 168.7%. These results indicate the Ryzen 9 PRO 8945HS is far better suited for content creation, software compilation, scientific computing, and any workload that can use more than 4 cores.

The Ryzen AI 5 430 shows its best relative performance in single-threaded PassMark, where the 6.4% gap is the smallest of all tests. This suggests it can handle light productivity tasks, web browsing, and office applications with acceptable responsiveness, though still behind the older chip. Its lower TDP of 28 W versus 45 W makes it a lower-power option, though the database does not record actual power consumption figures. Its LPDDR5X support could matter for thin-and-light system designs.

The Ryzen 9 PRO 8945HS also holds advantages in cache and PCIe connectivity. Its 16 MB shared L3 versus 4 MB L3 gives it a substantial edge in cache-sensitive workloads. Its 20 PCIe lanes versus 14 lanes allows more expansion headroom for discrete GPUs or storage devices. Both support ECC memory, which suits workstation-class mobile systems.

For integrated graphics, the Ryzen AI 5 430 uses the newer Radeon 840M, while the Ryzen 9 PRO 8945HS uses the Radeon 780M. The database does not include graphics benchmarks, so no quantitative comparison is possible. The newer Radeon 840M likely benefits from architectural improvements, but the data does not confirm this.

The Verdict

The benchmark data clearly favors the AMD Ryzen 9 PRO 8945HS. It wins all 15 recorded tests, with an average benchmark score of 41,963 versus 19,617 for the Ryzen AI 5 430. The Ryzen 9 PRO 8945HS ranks in the 88th percentile of all CPUs, while the Ryzen AI 5 430 ranks in the 73rd percentile. These are not adjacent performance tiers; they are separated by roughly two years of architectural evolution and a doubling of core count.

The Ryzen 9 PRO 8945HS is the choice for anyone who needs multi-threaded performance. Its 8 cores, 16 threads, 5.20 GHz boost clock, and 16 MB L3 cache deliver a 209.5% lead in Cinebench R23 multi-core and a 128.1% lead in PassMark multi-thread. It also holds a 32.7% single-core lead in Cinebench R15 and a 97.7% lead in Cinebench R23 single-core, meaning it wins even in lightly threaded scenarios.

The Ryzen AI 5 430 is not without merits, but they are narrower. Its single-thread PassMark score of 3,683 versus 3,920 shows it is within 6.4% of the older chip in that specific test. Its LPDDR5X support and newer Zen 5 architecture could offer advantages in memory bandwidth-sensitive tasks, though the database shows identical 89.6 GB/s bandwidth figures. Its 28 W TDP is lower than the 45 W TDP of the Ryzen 9 PRO 8945HS, which may appeal to systems prioritizing energy efficiency.

Data-driven verdict: the Ryzen 9 PRO 8945HS is the superior processor by a wide margin. The Ryzen AI 5 430 trades raw performance for lower power and newer memory options, but the measured benchmarks show no workload where it comes out ahead. Systems using the Ryzen 9 PRO 8945HS will handle demanding multi-threaded tasks far more effectively. Systems using the Ryzen AI 5 430 will use less power and support LPDDR5X, but they will be slower in every recorded test.
