AMD Ryzen AI 5 330 VS Intel Core Ultra 5 225H

At a high level, both the AMD Ryzen AI 5 330 and the Intel Core Ultra 5 225H share the same 28W TDP, integrated graphics, and 64-bit support — making them broadly comparable in thermal envelope and baseline feature parity. However, several meaningful differences emerge when looking closer at the underlying architecture and connectivity specs.

On process node, Intel holds a slight edge with a 3 nm fabrication versus AMD's 4 nm. A smaller node generally allows for greater transistor density, which can translate to improved power efficiency or performance-per-watt — though real-world gains depend heavily on architectural design. Intel also pulls ahead on connectivity with PCIe 5.0 support, compared to AMD's PCIe 4.0. This matters for users pairing the chip with next-generation NVMe SSDs or discrete GPUs that saturate PCIe 4.0 bandwidth. The Intel chip's higher maximum CPU junction temperature of 110 °C (vs. AMD's 100 °C) gives it slightly more thermal headroom before throttling, which can be an advantage in sustained workloads.

One area where the Ryzen AI 5 330 stands apart is platform flexibility: it is rated for both laptop and desktop use, while the Core Ultra 5 225H is laptop-exclusive. For system builders or OEMs targeting a wider range of form factors, the AMD chip offers a practical advantage. Overall, Intel holds the edge in process technology and I/O bandwidth, while AMD offers broader deployment flexibility at the same power budget.

The AMD Ryzen AI 5 330 and Intel Core Ultra 5 225H differ in their CPU speed configurations. The AMD Ryzen AI 5 330 has a CPU speed of 1 x 2 GHz and 3 x 2 GHz, while the Intel Core Ultra 5 225H features a CPU speed of 4 x 1.7 GHz and 8 x 1.3 GHz. Both processors utilize big.LITTLE technology, which allows them to efficiently manage power and performance by using different types of cores for different tasks.

In terms of CPU threads, the AMD Ryzen AI 5 330 offers 8 threads, while the Intel Core Ultra 5 225H provides 14 threads, offering greater multi-tasking capability. The AMD processor has a turbo clock speed of 4.5 GHz, whereas the Intel processor reaches a slightly higher turbo clock speed of 4.9 GHz, indicating a potential advantage in burst performance.

Both processors feature a locked multiplier, meaning that users cannot overclock them, but the AMD Ryzen AI 5 330 has a clock multiplier of 20, while the Intel Core Ultra 5 225H has a clock multiplier of 17, suggesting differences in how the processors handle clock speeds for specific tasks.

The AMD Ryzen AI 5 330 and Intel Core Ultra 5 225H show significant differences in their benchmark scores. The AMD Ryzen AI 5 330 has a PassMark result of 13,809, with a single-threaded score of 3,816. In comparison, the Intel Core Ultra 5 225H achieves a much higher overall PassMark result of 29,204, with a single-threaded score of 4,365.

These differences in PassMark results indicate that the Intel processor generally outperforms the AMD processor in both multi-threaded and single-threaded tasks, with a notably higher performance in both categories.

Overall, the Intel Core Ultra 5 225H demonstrates a clear lead in benchmark performance, particularly in single-threaded operations, as shown by its higher PassMark scores.

The integrated graphics of the AMD Ryzen AI 5 330 and Intel Core Ultra 5 225H differ in a few key areas. The AMD processor features a GPU turbo speed of 2800 MHz, while the Intel processor has a slightly lower GPU turbo speed of 2200 MHz.

Both processors support DirectX 12, with the Intel processor supporting the more advanced DirectX 12 Ultimate version. They both also support a maximum of four displays and share the same OpenGL version, 4.6. However, the AMD Ryzen AI 5 330 supports OpenCL version 2.1, while the Intel Core Ultra 5 225H supports OpenCL version 3, indicating a potential difference in their capabilities with OpenCL-based applications.

In summary, while both processors offer solid integrated graphics support, the Intel Core Ultra 5 225H has a slight edge in DirectX and OpenCL support, whereas the AMD Ryzen AI 5 330 offers a higher GPU turbo speed.

The AMD Ryzen AI 5 330 and Intel Core Ultra 5 225H have similar memory configurations but with some key differences. Both processors support DDR5 memory and have dual memory channels. However, the maximum RAM speed supported by the AMD Ryzen AI 5 330 is 8000 MHz, while the Intel Core Ultra 5 225H supports a slightly faster 8400 MHz RAM speed.

In terms of maximum memory capacity, the AMD Ryzen AI 5 330 supports up to 256GB of RAM, whereas the Intel Core Ultra 5 225H has a lower maximum memory amount of 128GB. Neither processor supports ECC memory.

Overall, the AMD Ryzen AI 5 330 offers a higher maximum memory capacity, while the Intel Core Ultra 5 225H has a slightly faster RAM speed capability.

The AMD Ryzen AI 5 330 and Intel Core Ultra 5 225H share most of the same instruction sets, including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2. These sets enable both processors to perform a wide range of operations efficiently. However, the key difference in their features is in multithreading support. The AMD Ryzen AI 5 330 uses multithreading, which allows it to handle more tasks simultaneously, while the Intel Core Ultra 5 225H does not support multithreading.

Both processors have the NX bit, which provides additional security by preventing the execution of code from certain regions of memory, a feature that both share.

In summary, the AMD Ryzen AI 5 330 stands out with its multithreading support, while the Intel Core Ultra 5 225H lacks this feature, despite sharing many of the same instruction sets and the NX bit security feature.
