Core and thread counts diverge sharply. AMD configures the Ryzen AI Max+ 392 with 12 cores and 24 threads, while Intel provides 5 cores and 6 threads. This 7-core and 18-thread difference explains the massive performance disparity in multi-threaded workloads. The AMD part's simultaneous multithreading doubles its thread count, whereas the Intel part offers only a single extra thread beyond its core count, suggesting limited or no hyperthreading capability on the extra core.

Clock speeds reinforce the performance gap. The AMD processor runs at a 3.20 GHz base clock and boosts to 5.00 GHz. The Intel part operates at 1.20 GHz base and 2.20 GHz boost, figures that are dramatically lower. Even in single-threaded scenarios, where clock speed matters most, the AMD chip's 5.00 GHz boost provides a substantial advantage over Intel's 2.20 GHz ceiling.

Cache hierarchies reveal distinct approaches. Both processors allocate 80 KB of L1 cache per core. The AMD part provides 1 MB of L2 per core, while Intel offers 1.25 MB per core, a slight Intel advantage at this level. The L3 cache, however, heavily favors AMD: 64 MB shared versus 8 MB shared. This 56 MB difference gives the AMD processor a major edge in workloads that benefit from large, fast on-die storage.

Power characteristics differ considerably. The AMD Ryzen AI Max+ 392 carries a 55 W TDP, while the Intel Processor U301L is rated at 15 W. This 40 W gap reflects the AMD part's higher performance ceiling and the Intel part's efficiency-focused design. Thermal and power delivery requirements will accordingly differ, with the AMD chip demanding more substantial cooling and battery capacity.

Memory support also diverges. AMD uses LPDDR5X memory across a quad-channel bus, delivering 256.0 GB/s of bandwidth. Intel supports DDR4 and DDR5 across a dual-channel bus, with no bandwidth figure recorded. The AMD configuration offers four times the memory channels and a memory type optimized for bandwidth, which supports its integrated graphics and compute-heavy workloads. The Intel part also supports ECC memory, a feature absent from the AMD specification.

PCIe connectivity differs as well. The AMD processor provides Gen 4 with 16 lanes, while Intel offers Gen 4 with 8 lanes. This doubles the available I/O bandwidth on the AMD side, benefiting discrete GPUs, NVMe storage, and other peripherals. The integrated graphics also differ: AMD pairs the CPU with Radeon 8060S, while Intel uses UHD Graphics 64EU. Socket compatibility separates the platforms entirely, with AMD using Socket FP11 and Intel using Socket 1700.

Where Each One Wins

The AMD Ryzen AI Max+ 392 wins in nearly every performance category by virtue of its recorded scores. Multi-threaded productivity tasks, content creation workloads, and scientific computing all benefit from the 12-core, 24-thread configuration, the 64 MB L3 cache, and the 256.0 GB/s memory bandwidth. The PassMark multi-thread score of 45,231 confirms that heavily parallel workloads represent the AMD part's natural domain, and the data compression score of 554,760 suggests exceptional capability in archiving, database operations, and similar throughput-heavy applications.

Single-threaded performance also favors AMD. The 3,927 single-thread score, achieved with a 5.00 GHz boost clock, indicates strong responsiveness in everyday applications, legacy software that uses few cores, and lightly threaded workloads. The 96th percentile ranking places this processor among the top 4% of all CPUs in the database, making it suitable for demanding mobile workstations and high-end laptops.

The Intel Processor U301L wins in efficiency-oriented scenarios. Its 15 W TDP, compared to AMD's 55 W, makes it suitable for fanless designs, ultra-portable devices, and applications where battery life takes priority over raw performance. The support for DDR4 memory allows system builders to use lower-cost memory modules, and the dual-channel configuration reduces motherboard complexity. The L2 cache allocation of 1.25 MB per core slightly exceeds AMD's 1 MB per core, which can benefit certain latency-sensitive workloads despite the overall cache deficit.

The Intel part's ECC memory support provides a niche advantage for reliability-focused deployments. The 8 MB L3 cache, while small relative to AMD, remains adequate for the Intel part's lower core count and reduced performance envelope. The 50th percentile ranking places it at the median of all CPUs, indicating competent mainstream performance for basic productivity, web browsing, and office applications.

The AMD part's 16 PCIe Gen 4 lanes support more expansion options than Intel's 8 lanes. This makes the AMD platform better suited for systems with discrete graphics or multiple high-speed storage devices. The Radeon 8060S integrated GPU, combined with quad-channel LPDDR5X memory, provides a graphics solution that exceeds typical integrated offerings, enabling light gaming and GPU-accelerated workloads without a discrete card.
