AMD Ryzen 5 40 vs AMD Ryzen AI Max PRO 485 Comparison

Head-to-Head Benchmarks

The AMD Ryzen 5 40 and the AMD Ryzen AI Max PRO 485 represent two very different tiers of AMD's mobile lineup, and the benchmark data confirms a substantial performance gap. The Ryzen AI Max PRO 485, based on the newer Zen 5 architecture, holds the clear advantage on paper, though the database currently contains no direct head-to-head benchmark results between the two chips. The Ryzen 5 40 has recorded benchmark scores across multiple test suites, while the AI Max PRO 485 has no scores listed in the database, leaving its real-world performance to be inferred from its architectural specifications.

For the Ryzen 5 40, the recorded data shows a Cinebench R23 multicore score of 4841 and a single-core score of 1150. In Cinebench R15, it achieves 790 multicore and 165.5 single-core. PassMark results show a multithread score of 9341, a single-thread score of 2477, integer math at 31598, floating point math at 15194, and data compression at 141533. The chip also records 6646 in data encryption, 6437 in extended instructions, 432 in physics, and 20 in find prime numbers. These scores place the Ryzen 5 40 at the 70th percentile of all CPUs, with an average benchmark score of 15882. Its nearest rivals include the AMD EPYC 75F3 with an average score of 15859 (0.1% ahead), the Intel Core Ultra 5 134U with 15910 (0.2% behind), the AMD EPYC 9354P with 15826 (0.4% ahead), and the AMD EPYC 9334 with 15940 (0.4% behind). The Ryzen 5 40 sits within a very tight cluster, no more than 0.4% away from any of these rivals in either direction, indicating that its aggregate performance is squarely in line with these server and mobile parts.

The AI Max PRO 485 has no benchmark entries in the database, and its average benchmark score is recorded as 0. Its percentile ranking is 50, which places it below the Ryzen 5 40's 70th percentile, but this is a function of missing data rather than measured performance. Without recorded scores, direct numerical comparisons between the two chips are not possible from the database. The architectural differences, however, provide strong indicators of expected relative performance, and these are examined in the following section.

Architecture Differences

The two processors differ fundamentally in their underlying designs. The Ryzen 5 40 uses the Zen 2 architecture with the Mendocino codename, while the AI Max PRO 485 uses the Zen 5 architecture with the Gorgon Halo codename. This generational gap spans multiple architecture iterations, with Zen 5 representing a significantly newer design. The process nodes also differ: the Ryzen 5 40 is built on TSMC's 6 nm process, while the AI Max PRO 485 uses a 4 nm process from the same foundry. The smaller process node typically enables higher transistor density and improved power efficiency, though the database does not list transistor counts for either chip.

Core configurations show a clear hierarchy. The Ryzen 5 40 has 4 cores and 8 threads, while the AI Max PRO 485 doubles that to 8 cores and 16 threads. Clock speeds follow suit: the Ryzen 5 40 has a base clock of 2.80 GHz and a boost clock of 4.30 GHz, whereas the AI Max PRO 485 runs at a base of 3.60 GHz and boosts to 5.00 GHz. The AI Max PRO 485 has both a higher base and a higher boost clock, compounding its core-count advantage. Thermal design power reflects this: the Ryzen 5 40 is rated at 15 W, while the AI Max PRO 485 is rated at 55 W, a substantial increase that indicates a much higher power envelope.

Cache hierarchies also differ significantly. 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 AI Max PRO 485 has 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. The L3 cache difference is particularly pronounced: 32 MB versus 4 MB, an eightfold increase. This larger cache can reduce memory latency and improve performance in cache-sensitive workloads.

Memory support and I/O capabilities are another major differentiator. The Ryzen 5 40 supports LPDDR5 memory over a dual-channel bus with a bandwidth of 88.0 GB/s. The AI Max PRO 485 supports LPDDR5X memory over a quad-channel bus with a bandwidth of 273.1 GB/s, more than three times the memory bandwidth. The AI Max PRO 485 also supports ECC memory, while the Ryzen 5 40 does not. PCIe connectivity differs as well: the Ryzen 5 40 has Gen 3 with 4 lanes (CPU only), while the AI Max PRO 485 has Gen 4 with 16 lanes (CPU only), offering both a newer PCIe generation and more lanes.

Integrated graphics are also different. The Ryzen 5 40 pairs with a Radeon 610M, while the AI Max PRO 485 includes a Radeon 8050S. The database does not provide specifications for these iGPUs, so a direct comparison of their capabilities is not possible from the recorded data. Socket types differ: the Ryzen 5 40 uses AMD Socket FT6, while the AI Max PRO 485 uses AMD Socket FP11. Both are mobile sockets, but they are not interchangeable. The die sizes differ as well, with the Ryzen 5 40 at 100 mm² and the AI Max PRO 485 at 70.6 mm². Release dates are also listed, with the Ryzen 5 40 released in 2025 and the AI Max PRO 485 in 2026. Neither chip has a launch MSRP recorded in the database.

The Verdict

Based on the recorded data, the AMD Ryzen AI Max PRO 485 is the more capable processor on paper. It has double the cores and threads, higher clock speeds, a larger cache, more memory bandwidth, and a newer process node. The Ryzen 5 40, by contrast, is a lower-power, lower-specification part designed for efficiency. The 15 W TDP of the Ryzen 5 40 versus the 55 W TDP of the AI Max PRO 485 indicates that the former is intended for lightweight mobile devices, while the latter is positioned for more demanding workloads.

The Ryzen 5 40 does have one advantage in the database: it has recorded benchmark scores and a 70th percentile ranking, while the AI Max PRO 485 has no benchmark data and a 50th percentile placeholder. This does not mean the Ryzen 5 40 is faster; it means the database has more information about its measured performance. The AI Max PRO 485's architectural specifications, particularly the 8-core Zen 5 configuration with 32 MB of L3 cache and 273.1 GB/s memory bandwidth, strongly suggest it will outperform the Ryzen 5 40 in multi-threaded and memory-intensive tasks, but this remains an inference from the specification data rather than a measured result.

Users who prioritize low power consumption and a compact footprint may find the Ryzen 5 40 suitable for basic mobile computing. Users who need higher throughput, more cores, and faster memory will likely prefer the AI Max PRO 485, assuming the workload can justify the higher TDP. The database does not include direct benchmark comparisons, so the verdict rests on architectural analysis rather than measured head-to-head results.

Where Each One Wins

The AMD Ryzen 5 40 wins in the database solely on the availability of measured benchmark results. It has scores across Cinebench R15, Cinebench R23, and multiple PassMark tests, giving it a concrete performance profile. Its 70th percentile ranking and average benchmark score of 15882 place it in a tight cluster with server-class EPYC parts and mobile Ultra chips, all within 0.4% of each other. The Ryzen 5 40 also wins on power efficiency, with a 15 W TDP that is 40 W lower than the AI Max PRO 485. Its smaller die size of 100 mm², while larger than the AI Max PRO 485's 70.6 mm², is paired with a lower power draw, which may be advantageous in thermally constrained devices.

The AMD Ryzen AI Max PRO 485 wins on nearly every architectural specification. It has double the cores and threads, higher base and boost clocks (3.60 GHz and 5.00 GHz versus 2.80 GHz and 4.30 GHz), and a larger cache configuration: 80 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3 versus 64 KB, 512 KB, and 4 MB respectively. It also has significantly more memory bandwidth at 273.1 GB/s versus 88.0 GB/s, supports ECC memory, uses a newer PCIe generation (Gen 4 versus Gen 3) with more lanes (16 versus 4), and is built on a smaller process node (4 nm versus 6 nm). Its integrated graphics, the Radeon 8050S, is a different and likely more capable part than the Radeon 610M, though the database does not provide specifications to quantify the difference.

For workloads that are single-threaded or lightly threaded, the AI Max PRO 485's higher clock speeds (5.00 GHz boost versus 4.30 GHz) give it an expected edge, though no direct measurements exist. For multi-threaded workloads, the core and thread advantage (8 cores versus 4) is decisive. For memory-heavy tasks such as data compression or large dataset manipulation, the quad-channel LPDDR5X with 273.1 GB/s bandwidth provides a substantial theoretical advantage over the dual-channel LPDDR5 at 88.0 GB/s. For applications that require ECC memory, the AI Max PRO 485 is the only option. For devices where power draw is critical, the Ryzen 5 40's 15 W TDP is the clear choice.
