AMD Ryzen 5 7400 vs AMD Ryzen AI 5 PRO 435G Comparison

The Verdict

The benchmark data splits this pairing into two very different personalities. The AMD Ryzen 5 7400 wins 8 of the 11 recorded head-to-head tests, while the AMD Ryzen AI 5 PRO 435G takes the remaining 3. For users whose workloads lean on multithreaded throughput, encryption, prime number searches, physics simulation, or sorting tasks, the Ryzen 5 7400 is the clear choice from the database. Its average benchmark score of 42,055 places it at the 88th percentile of all CPUs, and it edges out the nearest rival, the Intel Core i9-12900K, by 0.7% despite that rival having a higher raw score of 42,335. The Ryzen AI 5 PRO 435G, with an average of 40,718 and an 87th percentile ranking, is not far behind overall, but its strengths are concentrated in single-thread performance and floating-point math.

The Ryzen AI 5 PRO 435G is the pick for single-threaded responsiveness and floating-point workloads. It leads the Ryzen 5 7400 by 15.2% in the Passmark single-thread test, scoring 3,829 versus 3,248, and it wins floating-point math by 6.2%, posting 43,494 against 40,784. That makes it the better option for lightly threaded applications, legacy software, or math-heavy tasks that do not scale across cores. However, the Ryzen 5 7400 is the safer all-rounder for mixed productivity, content creation, or any workload that can exploit 12 threads, where its 7% lead in multithread score (21,712 versus 20,285) and 15.1% advantage in physics (1,150 versus 999) show a consistent edge.

The practical verdict: choose the Ryzen 5 7400 for general desktop work, encryption, compression, and anything multithreaded. Choose the Ryzen AI 5 PRO 435G only if single-core speed and floating-point throughput matter more than everything else, or if the newer 4 nm process and integrated Radeon 840M graphics are decisive factors.

Architecture Differences

The architectural split between these two processors is substantial. The AMD Ryzen 5 7400 belongs to the 7000 series and uses the Zen 4 architecture with the Raphael codename. It is built on a 5 nm process at TSMC, with a transistor count of 6,570 million and a die size of 71 mm². The AMD Ryzen AI 5 PRO 435G, by contrast, is part of the Ryzen AI PRO 400 generation, using a hybrid Zen 5 / Zen 5c design with the Gorgon Point codename. It is fabricated on a more advanced 4 nm process, though the database does not list its transistor count or die size.

Cache configurations differ notably. The Ryzen 5 7400 has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Ryzen AI 5 PRO 435G has 80 KB of L1 cache per core, 1 MB of L2 cache per core, but only 4 MB of L3 cache. That 12 MB difference in L3 cache is likely a factor in the Ryzen 5 7400's stronger multithreaded and encryption performance, as larger shared caches reduce memory latency for frequently accessed data.

The integrated graphics also differ. The Ryzen 5 7400 features Radeon Graphics, while the Ryzen AI 5 PRO 435G features the Radeon 840M. The newer Radeon 840M is part of a more modern platform, but the database does not provide direct graphics benchmarks, so the comparison is qualitative. Both CPUs support ECC memory and DDR5, but the Ryzen 5 7400 offers PCIe Gen 5 with 24 lanes (CPU only), while the Ryzen AI 5 PRO 435G is limited to PCIe Gen 4 with 10 lanes (CPU only). That gives the Ryzen 5 7400 a significant interface advantage for high-bandwidth storage or expansion cards.

The Ryzen AI 5 PRO 435G uses a hybrid core design with Zen 5 and Zen 5c cores, which explains its higher boost clock of 4.50 GHz versus 4.30 GHz for the Ryzen 5 7400, and its lower base clock of 2.00 GHz versus 3.30 GHz. The single-thread advantage in the benchmarks (15.2% higher) aligns with the newer Zen 5 architecture's improved IPC, while the smaller L3 cache and lower base clock likely contribute to the Ryzen 5 7400's wins in multithreaded tests.

Specification Differences

Both CPUs share the same core and thread counts: 6 cores and 12 threads. Both have a TDP of 65 watts, use AMD Socket AM5, support DDR5 memory in a dual-channel configuration, and have ECC memory support. Both are active production parts from AMD, and both are desktop market segments.

The differences are where the two diverge. The Ryzen 5 7400 has a base clock of 3.30 GHz and a boost clock of 4.30 GHz, while the Ryzen AI 5 PRO 435G has a base clock of 2.00 GHz and a boost clock of 4.50 GHz. The process node differs: 5 nm for the Ryzen 5 7400 versus 4 nm for the Ryzen AI 5 PRO 435G. Memory bandwidth favors the Ryzen AI 5 PRO 435G at 89.6 GB/s versus 83.2 GB/s.

PCIe support is a major difference. The Ryzen 5 7400 provides PCIe Gen 5 with 24 lanes (CPU only), while the Ryzen AI 5 PRO 435G provides PCIe Gen 4 with 10 lanes (CPU only). L3 cache is 16 MB shared on the Ryzen 5 7400 versus 4 MB on the Ryzen AI 5 PRO 435G, while L1 cache per core is 64 KB versus 80 KB. The integrated graphics differ (Radeon Graphics versus Radeon 840M). The Ryzen 5 7400 has an unlocked multiplier; the Ryzen AI 5 PRO 435G does not. Release dates are also distinct: the Ryzen 5 7400 was released on 2025-09-15, while the Ryzen AI 5 PRO 435G followed on 2026-03-01.

Head-to-Head Benchmarks

The biggest win for the AMD Ryzen 5 7400 is in data encryption, where it scores 14,865 against 12,111, a 22.7% advantage. That is the largest delta in the entire comparison and reflects the Ryzen 5 7400's larger L3 cache and higher base clock. Prime number finding is the second-largest gap: the Ryzen 5 7400 scores 79 versus 55, a 43.6% lead, though the absolute scores are low. Physics simulation also favors the Ryzen 5 7400 by 15.1%, with 1,150 versus 999. Random string sorting goes to the Ryzen 5 7400 by 13.5% (31,110 versus 27,407), and multithread performance is 7% higher (21,712 versus 20,285). Extended instructions favor the Ryzen 5 7400 by 6.6% (19,924 versus 18,697), and integer math is a narrow 1.6% win (64,733 versus 63,707). Data compression also goes to the Ryzen 5 7400 by 3.3% (261,749 versus 253,484).

The AMD Ryzen AI 5 PRO 435G takes three wins. The most significant is single-thread performance, where it scores 3,829 versus 3,248, a 15.2% lead. Floating-point math is its other substantial win, with 43,494 versus 40,784, a 6.2% advantage. The third win is the same single-thread test listed under a duplicate name, passmark_singlethread, with identical scores and delta. The Ryzen AI 5 PRO 435G also has a higher memory bandwidth (89.6 GB/s versus 83.2 GB/s) and a higher boost clock (4.50 GHz versus 4.30 GHz), which likely underpin its floating-point and single-thread successes.

The head-to-head results show a clear pattern: the Ryzen 5 7400 dominates in memory-sensitive and multithreaded workloads, while the Ryzen AI 5 PRO 435G excels in single-thread and floating-point tasks. The Ryzen 5 7400's 8 wins versus 3 wins for the Ryzen AI 5 PRO 435G, combined with its higher average score and 88th percentile ranking, make it the stronger overall processor in the database. The Ryzen AI 5 PRO 435G remains competitive for specific use cases, but the data does not support it as a general-purpose upgrade over the Ryzen 5 7400.
