Architecture Differences

Both chips belong to the Krackan Point family and the Ryzen AI 300 (Zen 5 / Zen 5c) generation, but the Ryzen AI 7 PRO 350 is explicitly listed with a Zen 5 architecture, while the Ryzen AI 7 345 does not carry an architecture field in the database. The PRO 350 has 8 cores and 16 threads, while the 345 has 6 cores and 12 threads. That difference is visible throughout the multi-threaded benchmark results.

The process node is identical: 4 nm at TSMC. The PRO 350 has a recorded die size of 195 mm², while the 345 has no die size entry. Both chips support DDR5 and LPDDR5X memory over a dual-channel bus with 89.6 GB/s of bandwidth. The PRO 350 supports ECC memory; the 345 does not.

PCIe connectivity differs. The PRO 350 provides Gen 4 with 16 lanes (CPU only), while the 345 provides Gen 4 with 14 lanes (CPU only). The integrated graphics also differ: the PRO 350 uses the Radeon 860M, while the 345 uses the Radeon 840M.

The boost clock differs as well. The PRO 350 boosts to 5.00 GHz, the 345 to 4.60 GHz. Base clocks are identical at 2.00 GHz. Cache hierarchy is the same per core (80 KB L1, 1 MB L2), but the PRO 350 doubles the L3 from 4 MB to 8 MB. Both parts are locked (multiplier unlocked is false), and both are mobile market segment products.

Head-to-Head Benchmarks

The Ryzen AI 7 PRO 350 wins 12 of the 15 recorded head-to-head comparisons. The Ryzen AI 7 345 wins the remaining 3. The scale of the PRO 350's victories is substantial in compute-heavy tests.

In Cinebench R23 multi-core, the PRO 350 scores 14278.5 against 11461 for the 345, a 19.7% advantage. Cinebench R15 multi-core shows an even larger gap: 2336.5 versus 1712, a 26.7% lead. The PRO 350 also wins Cinebench R23 single-core with 1954 versus 1818, a 7% margin.

PassMark integer math shows the largest percentage gap. The PRO 350 scores 84868, the 345 scores 63475, a 25.2% lead. Prime number finding follows closely: 81 versus 62, a 23.5% advantage. Data compression favors the PRO 350 at 281834 versus 237484, a 15.7% margin. Data encryption shows 14462 versus 11814, an 18.3% lead.

Floating point math results place the PRO 350 at 51639 versus 42621, a 17.5% advantage. Extended instructions go to the PRO 350 at 19955 versus 17003, a 14.8% margin. Random string sorting favors the PRO 350 at 31071 versus 25435, an 18.1% lead. Physics simulation results show 1318 versus 1089, a 17.4% advantage. The PassMark multi-thread score puts the PRO 350 at 23994 versus 19927, a 17% lead.

The Ryzen AI 7 345's wins are narrower but real. Cinebench R15 single-core goes to the 345 at 271 versus 247, a 9.7% margin. The two PassMark single-thread tests are effectively tied, with the 345 at 3875 and the PRO 350 at 3872, a 0.1% edge. These results indicate that in lightly threaded legacy workloads, the 345 can pull ahead despite its lower core count and lower boost clock.

The pattern is consistent: the PRO 350 dominates all heavily threaded workloads and shows a clear single-core improvement in Cinebench R23, while the 345 retains a slim lead in older single-thread tests.

Specification Differences

The two processors differ in several recorded specifications. The Ryzen AI 7 PRO 350 has 8 cores and 16 threads; the Ryzen AI 7 345 has 6 cores and 12 threads. Boost clock: 5.00 GHz for the PRO 350, 4.60 GHz for the 345. Base clock is the same at 2.00 GHz.

L3 cache: 8 MB on the PRO 350, 4 MB on the 345. L1 and L2 are identical per core. ECC memory support is present on the PRO 350, absent on the 345. PCIe lanes differ: 16 on the PRO 350, 14 on the 345, both Gen 4. Integrated graphics: Radeon 860M on the PRO 350, Radeon 840M on the 345.

The die size is recorded as 195 mm² for the PRO 350, with no entry for the 345. The architecture field lists Zen 5 for the PRO 350, while the 345 has no architecture entry. Release dates differ: the 345 launched on 2025-01-14, the PRO 350 on 2025-01-05. Part numbers also differ: 100-000000713 for the PRO 350, 100-000002122 for the 345.

Identical or shared specifications include the socket (AMD Socket FP8), TDP (28 W), process node (4 nm), foundry (TSMC), memory support (DDR5, LPDDR5X), memory bus (dual-channel), and memory bandwidth (89.6 GB/s). Both are mobile segment parts, both active in production, both locked, and neither has a launch MSRP recorded. The codename is Krackan Point for both, and both belong to the Ryzen AI 300 (Zen 5 / Zen 5c) generation lineup.

Where Each One Wins

The Ryzen AI 7 PRO 350 is the stronger processor for multi-threaded and throughput-oriented workloads. Its 8 cores and 16 threads, combined with double the L3 cache and a higher boost clock, produce decisive wins in Cinebench R23 multi-core (19.7% ahead), Cinebench R15 multi-core (26.7% ahead), and PassMark integer math (25.2% ahead). It also leads in data compression, data encryption, floating point math, extended instructions, prime number finding, random string sorting, physics, and the overall PassMark multi-thread score. The PRO 350's average benchmark score of 35719 places it in the 85th percentile, and its nearest rivals include the Intel Core 7 250H and Intel Core Ultra 9 185H, both within 0.1% of its average.

The Ryzen AI 7 345 wins in a narrow set of single-thread scenarios. Its Cinebench R15 single-core score of 271 beats the PRO 350's 247 by 9.7%. Its PassMark single-thread score of 3875 edges the PRO 350's 3872 by 0.1%. These results suggest the 345 retains an advantage in older single-threaded benchmarks, but the margin is small and does not carry over to Cinebench R23 single-core, where the PRO 350 leads by 7%. The 345's average benchmark score of 29461 puts it in the 81st percentile, with nearest rivals including the AMD Ryzen 7 3800X and Intel Core i5-13500HX.

For workloads that scale with core count, cache size, or boost frequency, the PRO 350 is the clear choice. For legacy single-thread benchmarks, the 345 holds a measurable but limited edge. The PRO 350 also adds ECC memory support and more PCIe lanes, which matters for systems requiring those features. The 345 offers the same 28 W TDP and same memory bandwidth, so power and memory characteristics do not differentiate the two. The recorded data shows a consistent performance hierarchy: the PRO 350 occupies a higher tier, while the 345 remains competitive only in narrow single-thread tests.
