AMD Ryzen AI 9 HX PRO 475 vs Intel Processor U300L Comparison

AMD Ryzen AI 9 HX PRO 475 vs Intel Processor U300L

The AMD Ryzen AI 9 HX PRO 475 and the Intel Processor U300L occupy distinctly different segments of the mobile processor market, with the data showing a clear performance hierarchy. The Ryzen AI 9 HX PRO 475 is a high-end, 12-core part that lands in the 94th percentile of all CPUs in the database, while the Intel Processor U300L is a 5-core entry-level chip sitting at the 50th percentile. The recorded benchmarks for the AMD part are extensive, while the Intel Processor U300L has no benchmark scores recorded in the database, making direct numerical comparisons impossible. However, the specification differences and the AMD chip's percentile ranking provide a clear picture of how these two parts diverge in capability and intended use.

Where Each One Wins

The AMD Ryzen AI 9 HX PRO 475 is designed for demanding multi-threaded workloads where its 12 cores and 24 threads can be fully utilized. Its benchmark scores show strength across a variety of compute-intensive tasks, including a PassMark multi-thread score of 36,487, a floating point math score of 79,887, and an integer math score of 126,829. These results indicate that the AMD part is well-suited for content creation, scientific computing, and any application that can leverage parallel processing. The single-thread score of 4,301 also demonstrates strong per-core performance, meaning it handles everyday responsiveness and lightly-threaded applications with ease. The 94th percentile ranking places it among the top processors in the database, competing closely with desktop-class parts like the AMD Ryzen 9 9950X and the AMD Ryzen 7 PRO 9745, which are only 0.2% and 0.4% ahead respectively.

The Intel Processor U300L, with its 5 cores and 6 threads, is positioned for basic mobile computing tasks such as web browsing, document editing, and media consumption. Its 15-watt TDP and 1.20 GHz base clock suggest a focus on power efficiency rather than raw compute capability. With no benchmark scores recorded, the database shows no direct wins for this part, but its specifications indicate it is capable of handling standard productivity workloads without strain. The 50th percentile ranking places it in the middle of the pack, which is typical for an entry-level mobile processor. The Intel part wins in efficiency metrics, as its 15-watt TDP is significantly lower than the AMD's 28 watts, making it the preferred choice for fanless or ultra-thin designs where battery life is prioritized over performance.

Architecture Differences

The architectural divide between these two processors is substantial. The AMD Ryzen AI 9 HX PRO 475 uses the Zen 5 architecture under the codename "Gorgon Point," built on a 4 nm process by TSMC. This modern node allows for high transistor density and efficiency, contributing to the chip's ability to deliver 12 cores and 24 threads within a 28-watt TDP. The AMD part features a hybrid configuration of Zen 5 and Zen 5c cores, as indicated by its generation label "Ryzen AI PRO 400 (Zen 5 / Zen 5c)." The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and a 16 MB shared L3 cache. The die size is listed at 233 mm², reflecting the complexity of the integrated Radeon 890M graphics and the 16 PCIe Gen 4 lanes.

The Intel Processor U300L relies on the older Raptor Lake architecture, codenamed "Raptor Lake-PS," built on Intel's 10 nm process. This is a more mature node that offers less density compared to AMD's 4 nm process. The Intel part has 5 cores and 6 threads, indicating a hybrid layout of performance and efficiency cores, though the exact core mix is not specified in the data. The cache configuration differs notably: it has 80 KB of L1 per core, but a larger 1.25 MB of L2 per core, and a smaller 8 MB shared L3 cache. The Intel chip uses the Intel Socket 1700, while the AMD chip uses AMD Socket FP8, confirming they are not interchangeable. The Intel part supports both DDR4 and DDR5 memory, whereas the AMD part supports only DDR5 and LPDDR5X, giving Intel a broader compatibility range for older systems.

Head-to-Head Benchmarks

There are no head-to-head benchmark results recorded in the database for these two processors, which limits direct side-by-side comparisons. The AMD Ryzen AI 9 HX PRO 475 has its own set of PassMark scores, but the Intel Processor U300L has none. This absence of data means the comparison must rely on the AMD chip's absolute scores and the percentile rankings of both parts.

The AMD part's multi-thread score of 36,487 is indicative of a processor that can handle substantial parallel workloads. Its data compression score of 461,650 and random string sorting score of 48,894 further confirm its strength in data manipulation tasks. The encryption score of 23,132 and extended instructions score of 31,969 show that the chip is not just about raw core count but also about efficient instruction execution. The physics score of 1,877, while lower in absolute terms, still reflects a capable processor for simulation tasks. The single-thread score of 4,301 is competitive with many desktop processors, ensuring that the AMD chip does not sacrifice responsiveness for multi-core performance.

The Intel Processor U300L, with no recorded scores, cannot be measured against these numbers. However, its 4.40 GHz boost clock is higher than the AMD's 5.20 GHz boost clock, which suggests that in single-threaded scenarios where the workload fits within the Intel part's smaller core count, it could deliver acceptable performance. The Intel part's 15-watt TDP is less than half of the AMD's 28 watts, meaning it will generate less heat and consume less power in sustained loads, but the trade-off is a significant reduction in multi-threaded throughput.
