AMD Ryzen AI Max 385

The AMD Ryzen AI Max 385 is a mobile processor built on the Zen 5 architecture, codenamed Strix Halo, and manufactured on TSMC's 4nm process. It features 8 cores and 16 threads, with a base clock of 3.60 GHz and a boost clock of 5.00 GHz, alongside a Radeon 8050S integrated GPU. The data places this chip in the 82nd percentile of all CPUs, with an average benchmark score of 24811, indicating it sits comfortably in the upper-midrange tier of mobile processors.

Benchmark Performance

The Ryzen AI Max 385 delivers a multi-threaded Cinebench R23 score of 15674, which is a strong result for an 8-core mobile part. This score reflects the efficiency of the Zen 5 architecture, translating into a substantial performance cushion for content creation workloads that scale across threads. Single-core performance in Cinebench R23 is 2212, a figure that confirms the chip's capability in lightly-threaded tasks such as web browsing and office productivity. In the older Cinebench R20 suite, the processor scores 6583 in multi-core and 929 in single-core, while in Cinebench R15 it reaches 1579 multi-core and 222 single-core; these results show consistent scaling across different versions of the benchmark.

The Passmark suite provides additional insight into specific workload characteristics. The multi-thread score is 18441, with integer math hitting 54901 and floating-point math at 37490. Data compression is a standout at 224838, indicating strong throughput for archiving and file management tasks. Extended instructions score 19254, and random string sorting reaches 23526, showing balanced performance in memory-intensive sorting operations. The single-thread Passmark score is 2056, while data encryption comes in at 10491 and the physics test at 1429. The find prime numbers test is notably low at 100, which suggests the processor's integer-heavy prime calculation performance is not a relative strength, though this is a narrow workload. The average benchmark score of 24811 places the chip in the 82nd percentile of all CPUs, which contextualizes its performance as above the typical processor.

Comparing to its nearest rivals, the Ryzen AI Max 385 trails the Intel Core i5-12450HX by a negligible -0.1% in average score, effectively a statistical tie. It also sits -0.3% behind the AMD Ryzen 9 6900HX, again within noise. Against the AMD Ryzen 7 5700X3D, it leads by 0.6%, and it is -0.7% behind the Intel Core i7-11850H. These margins are all under one percentage point, meaning the Ryzen AI Max 385 trades blows with these established parts across the aggregate benchmark suite. The Cinebench R23 multi-core score of 15674, however, is a specific data point where the chip can pull ahead or fall behind depending on the rival's own multi-core results, which are not in the provided data.

Platform and Compatibility

The Ryzen AI Max 385 uses the AMD Socket FP11, which is a mobile-specific socket design. It is built on the Zen 5 architecture under the Strix Halo codename, representing the current generation of AMD's high-end mobile lineup. The processor is fabricated on a 4nm process node at TSMC, with a die size consisting of two chiplets at 70.6 mm² each, for a combined silicon area that reflects the integration of both CPU and GPU components. The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and a shared 32 MB of L3 cache, providing a large pool of fast memory for compute-heavy tasks.

Memory support is limited to LPDDR5X, which is a low-power memory standard typically soldered onto the motherboard. The memory bus is quad-channel, offering a total memory bandwidth of 256.0 GB/s, a figure that is particularly important for the integrated Radeon 8050S GPU, as it relies on system memory for graphics data. ECC memory is supported, which is a notable feature for mobile platforms and can be relevant for error-sensitive workloads. The chip provides 16 PCIe Gen 4 lanes from the CPU, which is sufficient for a discrete GPU or high-speed SSDs, though the integrated graphics may reduce the need for a discrete solution in many configurations.

The production status is listed as active, with a release date of January 5, 2025. The multiplier is locked, meaning overclocking via clock multiplier adjustment is not available. The part number is 100-000001424. Since this is a mobile processor, the upgrade path is tied to the motherboard and system design; Socket FP11 is not a user-upgradeable desktop socket, so the chip is typically soldered or permanently mounted in a laptop. The platform's quad-channel LPDDR5X support and high memory bandwidth are distinct advantages for integrated graphics performance, but the lack of a replaceable CPU means the upgrade path is effectively the entire system.

How It Compares

vs. Intel Core i5-12450HX: The Ryzen AI Max 385 scores 24811 on average, which is -0.1% behind the Intel Core i5-12450HX's average of 24842. This is a near-dead heat, indicating that in aggregate multi-threaded and single-threaded workloads, the two processors are virtually indistinguishable. The AMD chip's higher memory bandwidth and integrated GPU may offer advantages in specific graphics or bandwidth-sensitive tasks, but the headline CPU performance is a tie.

vs. AMD Ryzen 9 6900HX: The Ryzen AI Max 385 trails the Ryzen 9 6900HX by -0.3%, with the rival posting an average score of 24897. The 6900HX is a previous-generation high-end part, and the fact that the newer Zen 5 chip lands just behind it by a fraction of a percent suggests that generational improvements are offset by the core count difference. The Ryzen AI Max 385's 8 cores match the 6900HX's core count, and the larger L3 cache and newer architecture keep it competitive.

vs. AMD Ryzen 7 5700X3D: The Ryzen AI Max 385 leads the Ryzen 7 5700X3D by 0.6%, with the rival averaging 24673. The 5700X3D is a desktop part with 3D V-Cache, which typically excels in gaming, but the average benchmark score here favors the mobile Ryzen AI Max 385. This indicates that for general-purpose compute, the Strix Halo chip holds a slight edge, though the 5700X3D's cache advantage could still shine in specific gaming scenarios.

vs. Intel Core i7-11850H: The Ryzen AI Max 385 is -0.7% behind the Intel Core i7-11850H, which averages 24974. The 11850H is an older Tiger Lake H-series part, and the margin here is small enough to be considered a tie. The Ryzen AI Max 385's newer architecture and higher boost clock help it keep pace with an Intel chip that has a higher thermal envelope in many laptop designs.

Power and Thermals

The Ryzen AI Max 385 has a TDP of 55 watts, which classifies it as a high-performance mobile processor that requires a robust cooling solution. A 55W TDP is typical for enthusiast-class laptops, where the chassis must dissipate heat from both the CPU and the integrated Radeon 8050S GPU under sustained loads. This power envelope implies that a laptop equipped with this chip will likely feature dual-fan cooling or a vapor chamber to maintain boost clocks without thermal throttling. The 4nm process node from TSMC helps with power efficiency, allowing the 8-core design to reach a 5.00 GHz boost clock within this thermal budget. The data suggests that the chip's performance is competitive with parts like the Intel Core i7-11850H, which also sits in a similar power class, but the Ryzen AI Max 385's integrated graphics capability means the cooling solution must account for combined CPU and GPU heat output. For users, this translates into a laptop that runs warm under load but should sustain performance in short bursts; for prolonged all-core workloads, the cooling system's quality will be the limiting factor. The 55W TDP is a mid-range figure for gaming and creator laptops, not as extreme as desktop replacement parts but higher than ultraportable chips. Given the 4nm fabrication and the 256.0 GB/s memory bandwidth, the chip's power draw is likely balanced between compute cores and the memory controller feeding the integrated GPU. A capable cooling solution is required to keep the 5.00 GHz boost clock sustainable, as the multi-threaded Cinebench scores suggest the chip can maintain high throughput when thermals permit.
