The Verdict

The data points to a straightforward conclusion: the AMD Ryzen 3 7335U is the stronger processor for almost every workload. It wins 14 of 15 benchmarks, and the losses are not close. The 54.8% gap in Cinebench R23 multi-core is decisive for anyone doing rendering, compilation, or other heavily threaded tasks. The 37.5% to 37.6% leads in floating point math and extended instructions matter for scientific computing and media encoding. The 28.8% advantage in encryption is relevant for security-sensitive applications and VPN workloads.

The only scenario where the Ryzen 5 40 wins is the Cinebench R15 single-core test, and that lead is just 8.9%. Anyone running legacy single-threaded applications that rely on that specific benchmark's characteristics might notice a slight edge, but the Ryzen 3 7335U wins the newer Cinebench R23 single-core test by 23.9%, which suggests the newer architecture is better suited to modern software.

For a buyer choosing between these two, the Ryzen 3 7335U is the pick for nearly all use cases. The Ryzen 5 40 makes sense only if the workload is exclusively old single-threaded benchmarks and the system needs the lower TDP. The Ryzen 5 40 is rated at 15 W TDP, while the Ryzen 3 7335U is rated at 28 W. That power difference is the main reason to consider the Ryzen 5 40, but it comes at a large performance cost.

Architecture Differences

The two processors come from different architectural generations. The Ryzen 5 40 uses Zen 2 architecture under the codename Mendocino. The Ryzen 3 7335U uses Zen 3+ architecture under the codename Rembrandt-R. Both are built on a 6 nm process at TSMC, so the manufacturing node is identical. The difference in performance comes from the architectural improvements in Zen 3+.

The die size tells part of the story. The Ryzen 5 40 has a die size of 100 mm², while the Ryzen 3 7335U has a die size of 208 mm². That is more than double the silicon area, which reflects the larger integrated graphics and additional cache in the Ryzen 3 7335U.

Cache configuration differs significantly. Both processors have 64 KB of L1 per core and 512 KB of L2 per core. The difference appears in L3 cache: the Ryzen 5 40 has 4 MB shared, while the Ryzen 3 7335U has 8 MB shared. That is double the L3 capacity, which explains part of the performance advantage in multi-threaded and cache-sensitive workloads.

The integrated graphics differ as well. The Ryzen 5 40 comes with Radeon 610M, while the Ryzen 3 7335U features Radeon 660M. The data does not include graphics benchmarks, but the naming convention and the larger die suggest the Radeon 660M is the more capable part.

Memory support also differs. The Ryzen 5 40 supports LPDDR5 memory, while the Ryzen 3 7335U supports DDR5. Both use dual-channel memory buses. The Ryzen 5 40 has a higher memory bandwidth at 88.0 GB/s, while the Ryzen 3 7335U is rated at 76.8 GB/s. Despite the lower memory bandwidth, the Ryzen 3 7335U still outperforms in the benchmarks, indicating that the architectural improvements in the cores matter more than raw memory throughput.

ECC memory support is another difference. The Ryzen 5 40 does not support ECC, while the Ryzen 3 7335U does. This makes the Ryzen 3 7335U more suitable for workstation or server-like use cases where data integrity is critical.

Specification Differences

The socket types differ. The Ryzen 5 40 uses AMD Socket FT6, while the Ryzen 3 7335U uses AMD Socket FP7. These are not interchangeable, so the motherboard selection will depend on which processor is chosen.

Clock speeds show a mixed picture. The Ryzen 5 40 has a base clock of 2.80 GHz and a boost clock of 4.30 GHz. The Ryzen 3 7335U has a base clock of 3.00 GHz and the same boost clock of 4.30 GHz. The higher base clock on the Ryzen 3 7335U contributes to its better sustained performance in multi-threaded workloads.

TDP ratings differ, with the Ryzen 5 40 at 15 W and the Ryzen 3 7335U at 28 W. The higher TDP on the Ryzen 3 7335U allows it to maintain higher clocks under load, which explains the large multi-core advantages.

PCIe support is different. The Ryzen 5 40 has PCIe Gen 3 with 4 lanes (CPU only). The Ryzen 3 7335U has PCIe Gen 4 with 20 lanes (CPU only). This is a significant difference for storage and expansion. The Ryzen 3 7335U offers more bandwidth and more lanes for NVMe drives, GPUs, or other peripherals.

Both processors have 4 cores and 8 threads, so the thread count is identical. Neither has an unlocked multiplier. The Ryzen 5 40 was released on 2025-09-30, while the Ryzen 3 7335U was released on 2023-01-03. Despite the later release date, the Ryzen 5 40 is based on older architecture.
