AMD's new Ryzen AI 7 345 laptop processor is now available for pre-order in Europe, but its specs tell a surprising story. The chip carries a Ryzen 7 label yet delivers less CPU performance than the cheaper Ryzen AI 5 340. This naming mismatch could confuse buyers expecting higher performance from a higher-tier model.
Ryzen AI 7 345 has only two Zen 5 cores.
The Ryzen AI 7 345 is part of AMD's latest laptop processor lineup alongside the Ryzen AI 5 340 and Ryzen AI 7 350. All three chips target thin-and-light notebooks, but the 345 sits in an odd position. It has only two Zen 5 cores, compared to three in the Ryzen AI 5 340, and its boost clock is lower.
Spec comparison
| Spec | Ryzen AI 7 345 | Ryzen AI 5 340 | Ryzen AI 7 350 |
|---|---|---|---|
| CPU cores | 2x Zen 5 + 4x Zen 5c | 3x Zen 5 + 4x Zen 5c | 4x Zen 5 + 4x Zen 5c |
| Boost clock (Zen 5) | 4.6 GHz | 4.8 GHz | 5.0 GHz |
| L3 cache | 8 MB | 16 MB | 16 MB |
| PCIe 4.0 lanes | 14 | 20 | 20 |
| iGPU | Radeon 840M (4 CUs) | Radeon 840M (4 CUs) | Radeon 860M (8 CUs) |
Key specs include 2x Zen 5 cores clocked at 4.6 GHz and 4x Zen 5c cores at 3.4 GHz. The L3 cache is halved to 8 MB, and PCIe 4.0 lanes are reduced to 14. The integrated GPU is a Radeon 840M with 4 compute units running at 2.9 GHz, identical to the Ryzen AI 5 340's iGPU.
Laptops with Ryzen AI 7 345 start at 999 EUR.
The Ryzen AI 7 345's CPU performance is reportedly slower than the Ryzen AI 5 340, according to Notebookcheck. The reduced core count, lower cache, and fewer PCIe lanes all contribute to this deficit. The iGPU remains the same, so graphics performance should match the lower-tier chip.
Laptops with the Ryzen AI 7 345 can now be pre-ordered in Europe starting at 999 EUR (about $1,162). Availability begins in June 2025. The pricing places it above the Ryzen AI 5 340, despite the 345 offering less CPU capability.
This launch follows AMD's recent pattern of mixing core architectures within a single product line. The Ryzen AI 7 345 combines Zen 5 and Zen 5c cores, but the lower count of full-size Zen 5 cores limits its performance. Consumers are advised to examine specifications closely instead of trusting model numbers alone.
The Ryzen AI 7 345 is confirmed to ship with the specs listed above. It offers a capable iGPU and modern features, but its CPU performance trails the Ryzen AI 5 340. For optimal CPU performance in this series, the Ryzen AI 5 340 or the higher-tier Ryzen AI 7 350 are recommended.
