Architecture Differences

The two processors come from different generations and use different Zen microarchitectures. The AMD Ryzen 5 7400 is a 7000 series desktop part based on Zen 4 with the codename Raphael. The AMD Ryzen AI 7 345 belongs to the Ryzen AI 300 generation and uses a hybrid Zen 5 / Zen 5c configuration with the codename Krackan Point. The process nodes also differ: the Ryzen 5 7400 is built on a 5 nm process at TSMC, while the Ryzen AI 7 345 uses a 4 nm process, also at TSMC. The transistor count and die size are recorded only for the Ryzen 5 7400, at 6,570 million transistors and a 71 mm² die, while those fields are not available for the Ryzen AI 7 345.

Cache layouts differ significantly between the two. The Ryzen 5 7400 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 a larger L1 at 80 KB per core, the same 1 MB of L2 per core, but only 4 MB of L3. This means the desktop part has four times the L3 capacity. The memory support also differs: the Ryzen 5 7400 supports DDR5 only, while the Ryzen AI 7 345 supports both DDR5 and LPDDR5X. Both use a dual-channel memory bus. The Ryzen 5 7400 has an ECC memory capability, while the Ryzen AI 7 345 does not. The PCIe configuration is different as well: the Ryzen 5 7400 offers Gen 5 with 24 lanes (CPU only), whereas the Ryzen AI 7 345 offers Gen 4 with 14 lanes (CPU only).

The integrated graphics differ. The Ryzen 5 7400 uses Radeon Graphics, while the Ryzen AI 7 345 uses the Radeon 840M. The Ryzen 5 7400 has an unlocked multiplier, meaning it is designed for overclocking, while the Ryzen AI 7 345 has a locked multiplier. The sockets are not interchangeable: the Ryzen 5 7400 uses AMD Socket AM5, and the Ryzen AI 7 345 uses AMD Socket FP8. The market segments reflect this, with the Ryzen 5 7400 classified as Desktop and the Ryzen AI 7 345 as Mobile.

Where Each One Wins

The AMD Ryzen 5 7400 is the stronger choice for multi-threaded workloads and for tasks that stress the memory cache hierarchy. Its passmark_multithread score of 21712 is 9 percent ahead of the Ryzen AI 7 345, and it wins passmark_physics by 5.6 percent. The desktop part also holds large leads in integer-heavy and sorting tasks: passmark_integer_math at 64733, passmark_find_prime_numbers at 79, and passmark_random_string_sorting at 31110. The 25.8 percent lead in passmark_data_encryption and the 17.2 percent lead in passmark_extended_instructions suggest the Ryzen 5 7400 is well suited to security-related and specialized instruction workloads. The 16 MB of shared L3, four times the capacity of the Ryzen AI 7 345, likely contributes to these wins in cache-sensitive tasks. Its higher 65 W TDP and unlocked multiplier also indicate a design aimed at sustained desktop performance.

The AMD Ryzen AI 7 345 is the better performer in single-threaded work. Its passmark_single_thread score of 3875 is 16.2 percent above the Ryzen 5 7400’s 3248, and it also wins in floating point math with 42621 versus 40784. The 4.60 GHz boost clock, higher than the 4.30 GHz of the Ryzen 5 7400, aligns with these results. The mobile part also wins on efficiency characteristics: its 28 W TDP is less than half of the 65 W TDP of the desktop chip. The Ryzen AI 7 345 uses the newer 4 nm process and supports both DDR5 and LPDDR5X memory, which makes it suited for mobile platforms where power and memory flexibility matter.

The overall benchmark record gives the Ryzen 5 7400 the edge in total wins, 8 to 3. Its average benchmark score of 42055 is significantly higher than the 29461 of the Ryzen AI 7 345, and its 88th percentile ranking versus 81st confirms the desktop part’s higher overall standing. The single-thread and floating point wins for the Ryzen AI 7 345 show that the mobile chip has clear strengths in those areas, but the breadth of victories for the Ryzen 5 7400 across compression, encryption, integer math, sorting, and multi-threaded tests gives it the wider performance profile.
