AMD Ryzen 5 3501U vs AMD Ryzen 5 7400 Comparison

The Verdict

The AMD Ryzen 5 7400 is the dominant processor in every single benchmark recorded in the database. Out of 11 head-to-head tests, it wins all 11, with no contest in any category. The Ryzen 5 3501U, a mobile chip from AMD's 3000 series, is outclassed by the 7400 across the board, from single-thread performance to heavily threaded workloads.

The data shows that the Ryzen 5 7400 delivers roughly 2.9 times the average benchmark score of the 3501U (42055 versus 14320). That gap is not a minor generational tick; it is a full platform leap. The 7400 sits at the 88th percentile of all CPUs in the database, while the 3501U sits at the 69th percentile. For a builder choosing between these two, the 7400 is the clear pick for any desktop workload, especially those that scale with cores, threads, and memory bandwidth.

The Ryzen 5 3501U remains relevant only in its intended mobile context. It is a 15-watt part designed for thin-and-light laptops, and its benchmark profile reflects that efficiency-first design. But if the choice is purely about performance, the 7400 wins every measurable category. The 3501U's only advantage is its power envelope, which is a platform consideration, not a raw performance one.

Architecture Differences

The two processors come from different eras and different design philosophies. The Ryzen 5 3501U is based on the Picasso generation, which uses the Zen+ microarchitecture. It is built on a 12 nm process at GlobalFoundries. The Ryzen 5 7400 uses the Zen 4 architecture, codenamed Raphael, and is manufactured on a 5 nm process at TSMC.

The transistor counts reflect this generational jump. The 3501U packs 4,940 million transistors on a 210 mm² die. The 7400 integrates 6,570 million transistors on a much smaller 71 mm² die. That density difference is a direct result of the process node shrink.

Cache hierarchies also differ significantly. The 3501U uses 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The 7400 uses 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. While the per-core L1 is smaller on the 7400, the L2 is doubled and L3 is quadrupled, which matters for workloads with large working sets.

Memory support is another major divider. The 3501U supports DDR4 memory on a dual-channel bus, with 38.4 GB/s of bandwidth. The 7400 supports DDR5 on a dual-channel bus, with 83.2 GB/s. That is a 2.17 times increase in theoretical memory bandwidth. The 7400 also supports ECC memory, while the 3501U does not.

PCIe connectivity differs as well. The 3501U uses PCIe Gen 3, while the 7400 uses PCIe Gen 5 with 24 lanes from the CPU. The 7400 also has an unlocked multiplier, making overclocking possible, whereas the 3501U is locked.

Head-to-Head Benchmarks

The Ryzen 5 7400 wins every benchmark in the head-to-head set. The largest margin comes in extended instructions, where the 7400 scores 19924 versus 3274, a delta of 83.6 percent in favor of the 7400. This test measures AVX and other extended instruction workloads, and the Zen 4 architecture's newer instruction set support shows clearly.

The smallest margin is in single-thread performance, where the 7400 scores 3248 versus 2136, a 34.2 percent advantage. That is still a substantial lead, but it confirms that the 3501U's Zen+ cores are not completely obsolete on a per-thread basis. The gap in multi-threaded workloads is much larger.

In integer math, the 7400 scores 64733 against 26321, a 59.3 percent lead. Floating-point math shows a 68.8 percent advantage, with 40784 versus 12707. Prime number finding, a test that stresses integer throughput and branch handling, shows the 7400 at 79 versus 21, a 73.4 percent lead.

Data compression is another major win for the 7400, scoring 261749 versus 87380, a 66.6 percent delta. Random string sorting shows a 66.5 percent gap, with 31110 versus 10414. Data encryption shows a 62.5 percent margin, 14865 versus 5580.

The multithread benchmark, which is a composite of several parallel workloads, gives the 7400 a score of 21712 versus 7071, a 67.4 percent lead. Physics simulation shows the 7400 at 1150 versus 483, a 58 percent delta.

The 7400's average benchmark score of 42055 places it close to the AMD Ryzen 9 PRO 8945HS, which averages 41963, a 0.2 percent difference. The Intel Core i9-12900K averages 42335, which is 0.7 percent higher than the 7400. The 3501U, by contrast, averages 14320, which is nearly identical to the AMD Ryzen Embedded V2546 at 14336.

Where Each One Wins

The Ryzen 5 7400 wins in every measured category, so the use-case split is not about choosing one over the other for a specific task. Instead, it is about platform context.

The 7400 is the correct choice for desktop builds where power delivery and cooling are not constrained. Its 65-watt TDP, DDR5 memory support, and PCIe Gen 5 connectivity make it suitable for modern high-throughput workloads. The 16 MB of L3 cache and 12 threads give it strong performance in multi-threaded applications like video encoding, software compilation, and scientific computing. The 88th percentile ranking confirms it is a high-tier desktop part.

The 3501U is a mobile processor with a 15-watt TDP, designed for battery-driven devices. Its 4 cores and 4 threads are sufficient for basic productivity and light multitasking, but the data shows it trails the 7400 by 59 to 84 percent in most compute-heavy tests. Its 69th percentile ranking is respectable for a low-power mobile chip, but it is not competitive with the 7400 in any direct comparison.

The memory bandwidth difference alone, 83.2 GB/s versus 38.4 GB/s, explains much of the gap in bandwidth-sensitive tests like data compression and random string sorting. The 7400's larger L3 cache, 16 MB versus 4 MB, also helps workloads with larger data footprints.

For anyone building a desktop system, the 7400 is the only logical pick from this pair. For anyone choosing a laptop part, the 3501U is the only mobile option in this comparison, and its benchmark scores should be interpreted within that power-constrained context. The data does not support any scenario where the 3501U outperforms the 7400, but it does show that the 3501U is a capable low-power processor for its segment.
