AMD Ryzen 5 7400 vs AMD Ryzen 7 PRO 7745 Comparison

Where Each One Wins

The benchmark data presents a clear and consistent picture: the AMD Ryzen 7 PRO 7745 wins every recorded head-to-head comparison against the AMD Ryzen 5 7400. Out of 11 benchmark tests, the Ryzen 7 PRO 7745 takes 11 wins, while the Ryzen 5 7400 records zero wins. This is not a close contest; it is a systematic advantage across every measured workload.

The Ryzen 7 PRO 7745’s largest margins come in compute-heavy tasks. In the PassMark find prime numbers test, it scores 166 versus 79, a 110.1% advantage. This test is highly sensitive to raw integer throughput and core scaling, and the Ryzen 7 PRO 7745 more than doubles the Ryzen 5 7400’s result. Similarly, integer math shows a 59.6% lead (103330 versus 64733), and floating point math shows a 55.3% lead (63332 versus 40784). These are the workloads where the extra two cores and higher boost clock of the Ryzen 7 PRO 7745 translate directly into performance.

The Ryzen 5 7400 does not win any category, but its closest relative performance is in single-threaded work. The passmark single thread score is 3248 versus 3849, a 18.5% deficit. That is still a solid lead for the Ryzen 7 PRO 7745, but it is the smallest gap in the entire dataset. For users running lightly threaded applications, the Ryzen 5 7400 is comparatively less disadvantaged, though it still trails.

For multi-threaded and data-heavy tasks, the Ryzen 7 PRO 7745 is the clear choice. The passmark multithread score is 32733 versus 21712, a 50.8% advantage. Data compression (386829 versus 261749, 47.8% ahead), data encryption (22821 versus 14865, 53.5% ahead), and extended instructions (29216 versus 19924, 46.6% ahead) all show the same pattern. The Ryzen 7 PRO 7745 is built for throughput, and the measurements confirm it.

The Ryzen 5 7400, meanwhile, is not a weak processor in absolute terms. Its average benchmark score of 42055 places it in the 88th percentile of all CPUs in the database, the same percentile as the Ryzen 7 PRO 7745. However, the Ryzen 7 PRO 7745’s average score of 43704 is higher, and the per-test deltas show that the Ryzen 5 7400 cannot match the Ryzen 7 PRO 7745 in any measured scenario.

Head-to-Head Benchmarks

The largest single win for the Ryzen 7 PRO 7745 is in the passmark find prime numbers test, where it scores 166 against 79 for the Ryzen 5 7400. That is a 110.1% delta, meaning the Ryzen 7 PRO 7745 delivers more than double the performance in this specific workload. This test is a strong indicator of pure integer throughput, and the result reflects the combined effect of more cores, higher clocks, and larger L3 cache.

The passmark integer math test shows a 59.6% advantage (103330 versus 64733). This is the second-largest proportional gap. Floating point math follows closely with a 55.3% lead (63332 versus 40784). These three tests represent the core arithmetic capabilities of the processors, and the Ryzen 7 PRO 7745 dominates all of them.

Data encryption shows a 53.5% advantage (22821 versus 14865), which is notable because encryption workloads often scale with both core count and cache size. The Ryzen 7 PRO 7745 has 32 MB of shared L3 cache, while the Ryzen 5 7400 has only 16 MB, and the benchmark results suggest this cache advantage matters. The multithread score of 32733 versus 21712 (50.8% ahead) reinforces the overall throughput picture.

Random string sorting shows a 50.3% lead (46759 versus 31110), and physics simulation shows a 47.7% lead (1699 versus 1150). Data compression is 47.8% ahead (386829 versus 261749), and extended instructions are 46.6% ahead (29216 versus 19924). The single-thread test is the smallest win at 18.5% (3849 versus 3248), but it is still a clear victory.

The consistency of these results is striking. Every single test, from the most compute-intensive to the most memory-dependent, shows the Ryzen 7 PRO 7745 ahead by a substantial margin. The Ryzen 5 7400 never comes within single digits of the Ryzen 7 PRO 7745, and in most tests the gap is 40% or more. The data does not support any scenario where the Ryzen 5 7400 is the faster processor.

Specification Differences

The most fundamental difference is core count. The AMD Ryzen 7 PRO 7745 has 8 cores and 16 threads, while the AMD Ryzen 5 7400 has 6 cores and 12 threads. This two-core, four-thread gap explains the large multi-threaded benchmark deltas.

Clock speeds also differ. The Ryzen 7 PRO 7745 has a base clock of 3.80 GHz and a boost clock of 5.30 GHz. The Ryzen 5 7400 has a base clock of 3.30 GHz and a boost clock of 4.30 GHz. The Ryzen 7 PRO 7745 is 0.50 GHz higher at base and 1.00 GHz higher at boost, which contributes to its single-thread advantage as well as its multi-thread lead.

Cache configuration is another key difference. Both processors have 64 KB of L1 cache per core and 1 MB of L2 cache per core. However, the L3 cache differs: the Ryzen 7 PRO 7745 has 32 MB shared, while the Ryzen 5 7400 has 16 MB shared. This 16 MB difference in L3 cache is significant for workloads that repeatedly access large datasets.

The market segment differs. The Ryzen 7 PRO 7745 is classified as Server/Workstation, while the Ryzen 5 7400 is classified as Desktop. This classification aligns with the Ryzen 7 PRO 7745’s higher core count and larger cache, which are oriented toward professional and server workloads.

The multiplier unlock status also differs. The Ryzen 7 PRO 7745 has a locked multiplier, while the Ryzen 5 7400 has an unlocked multiplier. This means the Ryzen 5 7400 can be overclocked by adjusting the multiplier, whereas the Ryzen 7 PRO 7745 cannot be overclocked through that method.

The release dates differ. The Ryzen 7 PRO 7745 was released on 2023-06-12, while the Ryzen 5 7400 was released on 2025-09-15. Both are currently active in production.

Architecture Differences

Both processors are built on the same Zen 4 architecture with the Raphael codename, and both are manufactured by TSMC on a 5 nm process node. The transistor count is identical at 6,570 million, and the die size is identical at 71 mm². This means the architectural foundation is the same; the differences come from configuration rather than design.

The core count difference is the primary architectural divergence. The Ryzen 7 PRO 7745 uses 8 cores, while the Ryzen 5 7400 uses 6 cores. Both are based on the same Zen 4 core design, but the Ryzen 7 PRO 7745 has two additional cores available for parallel work. The thread count scales accordingly: 16 threads versus 12 threads.

The L3 cache difference is also architectural. The Ryzen 7 PRO 7745 has 32 MB of shared L3 cache, while the Ryzen 5 7400 has 16 MB. This is a 100% increase in the Ryzen 7 PRO 7745’s favor. The L1 and L2 caches are identical on a per-core basis (64 KB and 1 MB respectively), but the total L2 cache is larger on the Ryzen 7 PRO 7745 because it has more cores (8 MB total versus 6 MB total).

Both processors support DDR5 memory with a dual-channel bus and 83.2 GB/s bandwidth. Both support ECC memory. Both use the AMD Socket AM5. Both have integrated Radeon Graphics. Both support PCIe Gen 5 with 24 lanes (CPU only). The memory and I/O architecture is identical.

The part numbers differ (100-000000599 for the Ryzen 7 PRO 7745, 100-000001900 for the Ryzen 5 7400), which is expected given the different configurations. The Ryzen 7 PRO 7745 belongs to the Ryzen 7 generation, while the Ryzen 5 7400 belongs to the Ryzen 5 generation, both under the 7000 series umbrella.

In summary, the architecture is the same Zen 4 design, but the Ryzen 7 PRO 7745 is a higher-tier configuration with more cores, more threads, more L3 cache, and higher clock speeds. The Ryzen 5 7400 is a lower-tier configuration with fewer cores, fewer threads, less L3 cache, and lower clocks, but it offers an unlocked multiplier. The benchmark data is consistent with these architectural differences.
