Architecture Differences

The AMD Ryzen 5 7400 is built on Zen 4 architecture with the Raphael codename, while the AMD Ryzen AI 7 445 uses Zen 5 architecture under the Gorgon Point codename. This generational difference is visible in the process node: the Ryzen 5 7400 uses a 5 nm process from TSMC, while the Ryzen AI 7 445 moves to TSMC's 4 nm node. Both chips have 6 cores and 12 threads, but they target different segments. The Ryzen 5 7400 is a desktop part for AMD Socket AM5, while the Ryzen AI 7 445 is a mobile chip on AMD Socket FP8.

The cache layouts differ notably. The Ryzen 5 7400 provides 64 KB of L1 cache per core and 1 MB of L2 per core, with 16 MB of shared L3. The Ryzen AI 7 445 offers a larger 80 KB L1 per core and the same 1 MB L2 per core, but its L3 drops to just 4 MB. This reduction in shared cache could impact workloads that depend on large working sets, although the newer architecture may compensate in other ways.

The Ryzen 5 7400 uses a dual-channel DDR5 memory interface with 83.2 GB/s of bandwidth. The Ryzen AI 7 445 also supports dual-channel DDR5 but adds LPDDR5X support, and its memory bandwidth rises to 89.6 GB/s. Both processors support ECC memory, which is relevant for error-sensitive workloads.

PCIe connectivity differs between the two. The Ryzen 5 7400 offers Gen 5 with 24 CPU lanes, while the Ryzen AI 7 445 is limited to Gen 4 with 14 CPU lanes. This gives the desktop part a significant expansion and bandwidth advantage for storage and graphics. Integrated graphics also differ: the Ryzen 5 7400 carries Radeon Graphics, while the Ryzen AI 7 445 uses the Radeon 840M.

The Ryzen 5 7400 has an unlocked multiplier, making it a candidate for overclocking, whereas the Ryzen AI 7 445 is locked. The desktop chip is also larger physically, with a die size of 71 mm² and 6,570 million transistors, while the mobile part's die size and transistor count are not recorded in the database.

Head-to-Head Benchmarks

The head-to-head data shows a clear pattern: the AMD Ryzen 5 7400 wins 9 of the 11 recorded comparisons, while the AMD Ryzen AI 7 445 takes the remaining 2. The desktop chip's biggest victory comes in PassMark data encryption, where its 14865 score beats the Ryzen AI 7 445's 10519 by 41.3%. Prime number finding shows a similar margin, with the Ryzen 5 7400 scoring 79 versus 56, a 41.1% lead.

The Ryzen 5 7400 also dominates in random string sorting, posting 31110 against 23488, a 32.5% advantage. Extended instructions favor the desktop part by 25.9%, with scores of 19924 and 15826. Data compression shows a 21.3% gap, as the Ryzen 5 7400 hits 261749 while the Ryzen AI 7 445 manages 215812. The multithread test confirms this trend: 21712 versus 18115, a 19.9% difference.

Physics and integer math also go to the Ryzen 5 7400, with leads of 17.8% and 11% respectively. The physics score of 1150 beats 976, while integer math comes in at 64733 against 58332. Floating point math is the closest contest among the desktop chip's wins: 40784 versus 39362, a modest 3.6% edge.

The Ryzen AI 7 445's two victories both come in single-thread tests, where its 3591 score is 9.6% higher than the Ryzen 5 7400's 3248. This single-thread advantage reflects the newer Zen 5 architecture and the higher 4.60 GHz boost clock. However, the desktop chip's higher base clock of 3.30 GHz versus 2.00 GHz helps explain its broader multi-thread dominance.

Looking at overall averages, the Ryzen 5 7400 has an average benchmark score of 42055, compared to 26936 for the Ryzen AI 7 445. This places the Ryzen 5 7400 at the 88th percentile of all CPUs in the database, while the Ryzen AI 7 445 sits at the 79th percentile. The Ryzen 5 7400's nearest rivals include the Intel Core i9-12900K at 42335 with a -0.7% delta, and the AMD Ryzen 9 PRO 8945HS at 41963 with a 0.2% delta. The Ryzen AI 7 445, by contrast, trades closely with the Intel Core i9-9900K at 27097 and the AMD Ryzen 7 5700G at 27051.

The Verdict

The data draws a straightforward distinction between these two processors. The AMD Ryzen 5 7400 is the stronger all-around performer, winning 9 of 11 head-to-head benchmarks and holding a 56.2% higher average score (42055 versus 26936). Its advantages are most pronounced in encryption, prime number finding, and string sorting, where it leads by 41.3%, 41.1%, and 32.5% respectively. This makes it the better choice for compute-heavy desktop workloads, particularly those that stress multi-threaded throughput and data processing.

The AMD Ryzen AI 7 445 justifies its existence through efficiency and single-thread capability. Its 28 W TDP is less than half the Ryzen 5 7400's 65 W, making it suitable for thin-and-light mobile designs. Its 9.6% single-thread lead and higher 4.60 GHz boost clock show that the Zen 5 architecture delivers per-core improvements, even if the overall package trails in multi-threaded tests. The mobile chip also supports LPDDR5X memory, which is not available on the desktop part.

For a desktop system where power draw is less constrained, the Ryzen 5 7400 is the clear pick based on benchmark results. It also offers PCIe Gen 5 connectivity with 24 lanes, compared to Gen 4 with 14 lanes on the mobile chip, and a much larger 16 MB L3 cache. The unlocked multiplier adds flexibility for users who want to adjust clocks.

For a laptop or compact mobile platform, the Ryzen AI 7 445's lower TDP and newer architecture make it the sensible option. Its single-thread performance is superior, and its memory bandwidth is slightly higher at 89.6 GB/s versus 83.2 GB/s. The trade-off is significant multi-thread performance: the Ryzen 5 7400 leads by 19.9% in multithread and by 21.3% in data compression, which matters for content creation and productivity tasks.

Neither chip has a recorded launch MSRP in the database, so pricing is not part of this comparison. The production status for both is Active, with the Ryzen 5 7400 released in September 2025 and the Ryzen AI 7 445 dated January 2026.

Specification Differences

The two processors diverge across nearly every core specification.
