AMD Ryzen 3 30 vs AMD Ryzen AI 7 345 Comparison

The Verdict

The benchmark database presents a decisive picture: the AMD Ryzen AI 7 345 wins every single head-to-head test recorded, with 11 wins out of 11 comparisons. The Ryzen 3 30 does not claim a single victory in any measured workload. The data indicates that the Ryzen AI 7 345 is the stronger processor across the board, with its smallest advantage being a 36.4% lead in single-thread performance and its largest being a 67.7% lead in prime number calculation.

The Ryzen 3 30, built on the older Zen 2 architecture with 4 cores and 8 threads, cannot match the 6-core, 12-thread Ryzen AI 7 345, which uses the newer Zen 5 / Zen 5c design. The average benchmark score difference is substantial: the Ryzen AI 7 345 records an average score of 29461, while the Ryzen 3 30 sits at 20137. This places the Ryzen AI 7 345 in the 81st percentile of all CPUs, while the Ryzen 3 30 lands in the 74th percentile.

For users selecting between these two mobile processors, the data supports choosing the Ryzen AI 7 345 for any workload where raw performance matters. The Ryzen 3 30, however, does have its place: its 15 W TDP and smaller footprint in the AMD Socket FT6 form factor may appeal to systems prioritizing efficiency over speed, but the benchmark results show no performance scenario where it comes out ahead.

Where Each One Wins

The Ryzen AI 7 345 wins every recorded benchmark category. Its largest margins appear in compute-heavy tasks: prime number finding shows a 67.7% advantage, floating point math shows 66.1%, and extended instructions show 64.3%. These results suggest the Ryzen AI 7 345 is particularly well-suited for scientific computing, encryption, and complex mathematical workloads.

The Ryzen 3 30 has no benchmark wins, so its case rests entirely on non-performance factors. It uses a 15 W TDP compared to the Ryzen AI 7 345's 28 W, and it operates in the AMD Socket FT6 platform, which may correspond to more compact or lower-power system designs. The Ryzen 3 30 also has a lower base clock of 2.40 GHz versus 2.00 GHz, though the Ryzen AI 7 345 boosts higher to 4.60 GHz against the Ryzen 3 30's 4.10 GHz.

For single-threaded responsiveness, the Ryzen AI 7 345 leads by 36.4%, which is its narrowest margin but still a clear win. For multi-threaded work, the gap widens to 54.7%, reflecting the core and thread advantage. The data shows no workload category where the Ryzen 3 30 compensates for its deficits.

Architecture Differences

The two processors come from different architectural generations. The Ryzen 3 30 uses the Zen 2 architecture with the Mendocino codename, fabricated on a 6 nm process by TSMC. The Ryzen AI 7 345 uses the Zen 5 / Zen 5c hybrid design under the Krackan Point codename, built on a 4 nm process, also by TSMC. The newer process node provides a denser transistor layout, which contributes to the Ryzen AI 7 345's higher performance despite its higher power envelope.

Core counts differ significantly: the Ryzen 3 30 has 4 cores and 8 threads, while the Ryzen AI 7 345 has 6 cores and 12 threads. This 50% increase in core count translates directly into multi-threaded performance gains. Cache structures also diverge. The Ryzen 3 30 carries 64 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The Ryzen AI 7 345 uses 80 KB of L1 per core, 1 MB of L2 per core, and also has 4 MB of L3. The larger per-core L2 cache on the Ryzen AI 7 345 likely helps with data-heavy workloads.

Memory support differs as well. The Ryzen 3 30 supports LPDDR5 memory, while the Ryzen AI 7 345 supports both DDR5 and LPDDR5X. Memory bandwidth is close: the Ryzen 3 30 records 88.0 GB/s, and the Ryzen AI 7 345 records 89.6 GB/s, a minor edge. PCIe connectivity also differs: the Ryzen 3 30 uses Gen 3 with 4 CPU lanes, while the Ryzen AI 7 345 uses Gen 4 with 14 CPU lanes, which affects expansion and storage options.

Integrated graphics differ as well. The Ryzen 3 30 includes the Radeon 610M, while the Ryzen AI 7 345 includes the Radeon 840M. The newer Radeon 840M benefits from the same architectural improvements as the CPU cores, though the database does not record separate graphics benchmarks. The Ryzen 3 30 has a die size of 100 mm², while the Ryzen AI 7 345 does not have a recorded die size in the data.

Specification Differences

The core specification table shows several key differences between the two AMD processors. The Ryzen 3 30 has 4 cores and 8 threads, while the Ryzen AI 7 345 has 6 cores and 12 threads. Base clocks differ: the Ryzen 3 30 runs at 2.40 GHz, and the Ryzen AI 7 345 runs at 2.00 GHz. Boost clocks reverse this trend, with the Ryzen 3 30 peaking at 4.10 GHz and the Ryzen AI 7 345 reaching 4.60 GHz.

Thermal design power differs by 13 W. The Ryzen 3 30 has a TDP of 15 W, while the Ryzen AI 7 345 has a TDP of 28 W. This higher power budget allows the Ryzen AI 7 345 to sustain higher clocks and feed more cores.

Socket compatibility separates the pair completely. The Ryzen 3 30 uses AMD Socket FT6, and the Ryzen AI 7 345 uses AMD Socket FP8. These are not interchangeable, meaning system designs must choose one platform or the other.

Cache configurations differ in size and distribution. The Ryzen 3 30 uses 64 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The Ryzen AI 7 345 uses 80 KB of L1 per core, 1 MB of L2 per core, and also 4 MB of shared L3. The Ryzen AI 7 345 doubles the L2 cache per core, which benefits workloads with high cache reuse.

Memory support and bandwidth show modest differences. The Ryzen 3 30 supports LPDDR5 with 88.0 GB/s bandwidth. The Ryzen AI 7 345 supports DDR5 and LPDDR5X with 89.6 GB/s bandwidth. Both use dual-channel memory buses. Neither processor supports ECC memory.

PCIe capabilities differ substantially. The Ryzen 3 30 provides Gen 3 with 4 CPU-only lanes. The Ryzen AI 7 345 provides Gen 4 with 14 CPU-only lanes. This gives the Ryzen AI 7 345 more than three times the PCIe lane count and double the data rate per lane, affecting connectivity for GPUs, NVMe drives, and other peripherals.

Integrated graphics are different models: the Ryzen 3 30 uses Radeon 610M, and the Ryzen AI 7 345 uses Radeon 840M. The process node also differs (6 nm versus 4 nm), and the Ryzen AI 7 345 has a codename of Krackan Point, while the Ryzen 3 30 uses Mendocino. The Ryzen 3 30 has a recorded die size of 100 mm², but the Ryzen AI 7 345 lacks a die size figure in the database. The Ryzen AI 7 345 has a part number of 100-000002122, while the Ryzen 3 30's part number is unknown. Release dates place the Ryzen AI 7 345 earlier in 2025, while the Ryzen 3 30 appeared later in the same year.
