The average benchmark score for the Ryzen AI 5 435 is 28128, placing it in the 80th percentile of all CPUs, while the Ryzen 5 40 averages 15882, which sits in the 70th percentile. This gap of 12246 points in average score indicates that the Ryzen AI 5 435 is not just a minor revision but a substantially more capable part across the board.

Where Each One Wins

The data is unambiguous: the AMD Ryzen AI 5 435 wins every single benchmark category recorded in the database. There are zero wins for the AMD Ryzen 5 40 across the 15 head-to-head tests. The Ryzen AI 5 435’s victories span synthetic render workloads, math operations, encryption, and compression tasks, showing a comprehensive advantage rather than a niche one.

For multi-threaded and heavily parallel workloads, the Ryzen AI 5 435 is the clear choice. In Cinebench R23 multi-core, it scores 11333 against the Ryzen 5 40’s 4841, a delta of 57.3%. The PassMark multithread test shows a similar story, with scores of 19000 and 9341 respectively, a 50.8% gap. The Ryzen AI 5 435 also dominates in floating point math, scoring 40627 versus 15194, a 62.6% lead, and in integer math, scoring 61026 against 31598, a 48.2% advantage. For users running video encoding, 3D rendering, or scientific simulations, the Ryzen AI 5 435 delivers roughly double the throughput in several tests.

Single-thread performance also favors the Ryzen AI 5 435 decisively. In Cinebench R23 single-core, it scores 1816 versus 1150, a 36.7% lead. The PassMark single-thread test shows 3734 against 2477, a 33.7% gap. This means the Ryzen AI 5 435 is faster not only in parallel tasks but also in everyday responsiveness and lightly threaded applications like web browsing, office work, and older games that rely on one or two cores.

The Ryzen AI 5 435’s lead extends to specialized operations. In PassMark extended instructions, it scores 16197 versus 6437, a 60.3% margin, indicating strong SIMD and vector processing capabilities. In data encryption, it scores 11110 against 6646, a 40.2% lead, and in data compression, 225374 versus 141533, a 37.2% advantage. The Ryzen 5 40 cannot claim a single category where it outperforms its rival, so the use-case split is one-sided: the Ryzen AI 5 435 is the superior processor for all measured workloads.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen 5 40 uses the Zen 2 architecture under the Mendocino codename, fabricated on a 6 nm process node at TSMC. It has 4 cores and 8 threads, with a base clock of 2.80 GHz and a boost clock of 4.30 GHz. The Ryzen AI 5 435 uses the newer Zen 5 architecture under the Gorgon Point codename, on a 4 nm process node, also from TSMC. It has 6 cores and 12 threads, with a lower base clock of 2.00 GHz but a higher boost clock of 4.50 GHz.

Cache configurations differ substantially. The Ryzen 5 40 has 64 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The Ryzen AI 5 435 has 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3 cache. The larger per-core L1 and doubled L2 cache on the Ryzen AI 5 435 likely contributes to its strong single-thread performance, despite its lower base clock.

Memory support and platform connectivity also diverge. The Ryzen 5 40 supports LPDDR5 memory on a dual-channel bus with a bandwidth of 88.0 GB/s, and it does not support ECC memory. The Ryzen AI 5 435 supports DDR5 and LPDDR5X memory, also dual-channel, with a slightly higher bandwidth of 89.6 GB/s, and it does support ECC memory. PCIe connectivity differs as well: the Ryzen 5 40 offers Gen 3 with 4 lanes (CPU only), while the Ryzen AI 5 435 offers Gen 4 with 14 lanes (CPU only), a significant upgrade for attached devices.

The integrated graphics are different as well. The Ryzen 5 40 uses the Radeon 610M, while the Ryzen AI 5 435 uses the Radeon 840M. The sockets are not interchangeable: the Ryzen 5 40 uses AMD Socket FT6, and the Ryzen AI 5 435 uses AMD Socket FP8. The thermal design power also differs, with the Ryzen 5 40 rated at 15 W and the Ryzen AI 5 435 rated at 28 W, which reflects the higher core count and performance envelope of the latter.
