AMD Ryzen AI Max PRO 385

The AMD Ryzen AI Max PRO 385 is a mobile processor built on the Zen 5 architecture (codenamed Strix Halo) and fabricated on a 4 nm TSMC process. It features 8 cores and 16 threads, with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. The chip integrates a Radeon 8050S GPU, supports LPDDR5X memory over a quad-channel bus with 256.0 GB/s of bandwidth, and includes ECC memory support. With an average benchmark score of 45260, it sits in the 92nd percentile of all CPUs, placing it firmly in high-performance territory for a mobile part.

How It Compares

The nearest rival in average benchmark score is the Intel Core i9-12900KS, which posts an average score of 45023. The Ryzen AI Max PRO 385 leads by a slim 0.5% margin. This is a desktop flagship-class chip from a previous generation, and the mobile AMD part edges it out in aggregate performance. The delta is tiny enough that real-world differences would be negligible in most workloads, but the result underscores how close modern high-end mobile silicon has come to desktop parts.

The AMD EPYC 4344P is a server processor with an average score of 45586, putting it 0.7% ahead of the Ryzen AI Max PRO 385. That gap is essentially a statistical tie. The EPYC part is designed for data-center throughput, yet the mobile Ryzen chip trades blows with it in the aggregate benchmark suite. This suggests the Ryzen AI Max PRO 385 carries substantial compute headroom for a laptop-class component, even when compared to a dedicated server offering.

Another close competitor is the Intel Core i5-14600, which averages 45594 and also leads by 0.7%. The Core i5 is a mainstream desktop chip, and the Ryzen AI Max PRO 385 trails it by less than a single percentage point. For a mobile processor, that is a striking result — the data shows the AMD part delivers near-desktop-mainstream performance while operating within a mobile power envelope.

The Intel Core i9-13950HX is the only other mobile chip in the rival set, with an average score of 44747. The Ryzen AI Max PRO 385 is 1.1% ahead of it. The 13950HX is a high-core-count HX-series laptop processor, and the AMD chip beats it in aggregate benchmarks despite having fewer cores (8 vs. the Intel part's higher core count). This indicates the Zen 5 architecture's per-core efficiency and memory bandwidth play a significant role in closing the gap.

Power and Thermals

The Ryzen AI Max PRO 385 carries a TDP of 55 watts. This places it in the upper mid-range of mobile processor power classes — not an ultra-low-power part, but also not in the extreme high-TDP tier reserved for desktop-replacement HX chips. A 55 W TDP implies the need for a capable cooling solution, typically a dual-fan laptop design with multiple heat pipes, rather than a slim ultrabook chassis.

Given the 4 nm process node from TSMC, the data suggests this chip can sustain high boost clocks under load without requiring exotic cooling. The 256.0 GB/s of memory bandwidth and integrated Radeon 8050S GPU also contribute to thermal load, as the memory controllers and iGPU share the same die. Laptop designs pairing this processor with the 55 W TDP will likely feature robust thermal modules to maintain sustained multi-core performance.

The quad-channel LPDDR5X memory support adds to the power draw, as higher-bandwidth memory subsystems consume more energy. However, the 55 W TDP remains the defining thermal constraint. For system integrators, this means the Ryzen AI Max PRO 385 fits into performance-focused laptops and mobile workstations, not passively cooled devices. A capable air cooler or a modest liquid-cooling solution would be appropriate for this class of processor.

Who Should Consider It

The Ryzen AI Max PRO 385 is well-suited for content creators and professionals who need strong multi-threaded performance in a mobile package. Its Cinebench R23 multi-core score of 28424 and PassMark multithread score of 33441 indicate it can handle video rendering, 3D modeling, and software compilation with ease. The 92nd percentile ranking reinforces that this is a top-tier mobile CPU for demanding productivity workloads.

Gamers will find the integrated Radeon 8050S GPU paired with 256.0 GB/s of memory bandwidth to be a compelling combination, especially in thin-and-light laptops where discrete GPUs are not an option. While the CPU's single-thread score of 4012 in Cinebench R23 is strong, the real gaming advantage comes from the high memory bandwidth feeding the iGPU. This makes it a viable choice for 1080p gaming on the go, though users seeking maximum frame rates should look elsewhere.

Office and general productivity users are overserved by this chip, as its capabilities far exceed word processing or spreadsheet tasks. The PassMark single-thread score of 4052 and data compression score of 399839 show snappy responsiveness, but the cost and power draw are unjustified for basic office use. This processor is aimed at users who need workstation-level compute in a laptop form factor.

Benchmark Performance

The benchmark data paints a picture of a mobile processor that punches well above its class. The Cinebench R23 multi-core score of 28424 is particularly telling — it places the Ryzen AI Max PRO 385 in the same performance sphere as desktop chips with higher core counts. The PassMark multithread score of 33441 corroborates this, showing strong scaling across the 8 cores and 16 threads. Against the Intel Core i9-13950HX, which scores 44747 on average, the AMD chip is 1.1% ahead — a meaningful edge for a mobile part with fewer cores, attributable to the Zen 5 architecture's efficiency.

Single-thread performance is equally impressive. The Cinebench R23 single-core score of 4012 and PassMark single-thread score of 4052 indicate excellent responsiveness in lightly-threaded applications. These figures help explain why the chip holds its own against the Intel Core i5-14600, which leads by only 0.7% in average score. The 5.00 GHz boost clock is clearly effective in latency-sensitive workloads.

Memory-intensive tasks show the benefit of the 256.0 GB/s bandwidth. The PassMark data encryption score of 19947 and random string sorting score of 41537 are strong, reflecting the quad-channel LPDDR5X subsystem. The floating-point math score of 72648 and integer math score of 108717 further demonstrate the chip's arithmetic throughput. Meanwhile, the extended instructions score of 33915 suggests robust SIMD performance, useful for scientific and engineering workloads.

The aggregate benchmark score of 45260 places the Ryzen AI Max PRO 385 in the 92nd percentile of all CPUs. Its nearest rivals — the Core i9-12900KS, EPYC 4344P, Core i5-14600, and Core i9-13950HX — all sit within a 1.8% band of each other, making this a tightly contested performance cluster. The delta percentages are small, but the AMD chip's position at 45260 shows it leads one desktop flagship, trails two others marginally, and beats the competing mobile HX chip. For a 55 W mobile processor, that is an exceptional result, indicating that Zen 5's IPC gains and the high-bandwidth memory system deliver outsized performance relative to power draw.
