AMD Ryzen AI 9 H 365 VS Intel Core Ultra 7 255H

Both the AMD Ryzen AI 9 365 and the Intel Core Ultra 7 255H share a 28W TDP and integrated graphics support, placing them in the same thermal envelope and making them direct competitors for thin-and-light laptop designs. Both are fully 64-bit capable, so there are no architectural limitations to consider on that front.

The key differentiators lie in process node, PCIe generation, and thermal headroom. Intel's chip is built on a 3 nm process versus AMD's 4 nm, which in theory gives Intel a slight edge in transistor density and potential power efficiency. More practically significant is the PCIe version: Intel supports PCIe 5 while AMD tops out at PCIe 4 — meaning the Core Ultra 7 255H can take advantage of next-generation NVMe SSDs and GPUs with twice the bandwidth per lane, which matters for future-proofing and high-throughput storage workloads. Intel also has a higher maximum CPU temperature ceiling at 110 °C versus AMD's 100 °C, giving it slightly more thermal headroom before throttling kicks in under sustained load.

One notable AMD advantage: the Ryzen AI 9 365 is listed as compatible with both Laptop and Desktop form factors, while the Core Ultra 7 255H is laptop-only. Overall, Intel holds a modest but real edge in this group thanks to the newer PCIe generation and finer process node, though neither chip is definitively superior across all dimensions.

The AMD Ryzen AI 9 H 365 and Intel Core Ultra 7 255H both offer impressive performance specs, though with some differences in their configurations. The Ryzen AI 9 H 365 features a CPU speed with a combination of 4 cores running at 2 GHz and 6 cores running at 2 GHz, alongside a turbo clock speed of 5 GHz. In contrast, the Intel Core Ultra 7 255H has a CPU speed of 6 cores running at 2 GHz and 8 cores running at 1.5 GHz, with a slightly higher turbo clock speed of 5.1 GHz. Both processors also use big.LITTLE technology to optimize performance and power efficiency.

When it comes to threads, the Ryzen AI 9 H 365 supports 20 threads, while the Intel Core Ultra 7 255H has 16 threads. This means the AMD processor is capable of handling more simultaneous tasks, which could be beneficial for multi-threaded workloads. Both processors come with the same L3 cache size of 24 MB, ensuring efficient data storage for both models.

Neither processor has an unlocked multiplier, which limits the ability to overclock for manual performance tweaks. Both chips also share the same clock multiplier of 20, which is important for determining the relationship between the base clock and CPU speed. Overall, while both processors are well-equipped for high performance, the Ryzen AI 9 H 365 offers more threads, while the Intel Core Ultra 7 255H provides a slightly faster turbo clock speed.

In terms of benchmark performance, the AMD Ryzen AI 9 H 365 and Intel Core Ultra 7 255H have distinct results. The Ryzen AI 9 H 365 scores a total of 29,245 in the PassMark benchmark, while the Intel Core Ultra 7 255H slightly outperforms it with a score of 30,756. This difference suggests that the Intel processor has a slight edge in overall multi-threaded performance.

Looking at single-threaded performance, the Ryzen AI 9 H 365 has a PassMark result of 3,571, while the Intel Core Ultra 7 255H has a higher score of 4,373. This indicates that the Intel chip delivers better performance in tasks that rely heavily on single-core speeds.

Overall, the Intel Core Ultra 7 255H shows higher performance scores both in total benchmarking and single-threaded tasks compared to the AMD Ryzen AI 9 H 365, although both processors perform well in their respective categories.

The integrated graphics of the AMD Ryzen AI 9 H 365 and Intel Core Ultra 7 255H both offer solid visual performance, but with distinct specifications. The Ryzen AI 9 H 365 is equipped with a Radeon 880M GPU, which has a GPU clock speed of 400 MHz and can boost up to 2,900 MHz. In comparison, the Intel Core Ultra 7 255H features an Arc 140T GPU, with a lower base clock speed of 300 MHz but a turbo clock speed of 2,250 MHz.

Both processors support up to 4 displays and have similar OpenGL and DirectX support, with both supporting OpenGL version 4.6 and DirectX 12. However, the Intel Core Ultra 7 255H has a slight advantage in DirectX support, as it supports the more advanced DirectX 12 Ultimate, while the Ryzen AI 9 H 365 only supports the standard DirectX 12.

In terms of hardware specifications, the Ryzen AI 9 H 365 features 48 texture mapping units (TMUs), 16 render output units (ROPs), and 768 shading units. On the other hand, the Intel Core Ultra 7 255H has 64 TMUs, 32 ROPs, and 1,024 shading units. These differences indicate that the Intel graphics have more computational power in terms of texture handling and shading, which may lead to a more powerful overall graphical performance.

The AMD Ryzen AI 9 H 365 and Intel Core Ultra 7 255H offer similar memory specifications in several aspects, but with notable differences. Both processors support DDR5 memory and feature dual memory channels, which is common in modern high-performance processors. The maximum RAM speed supported by the Ryzen AI 9 H 365 is 8000 MHz, while the Intel Core Ultra 7 255H supports a slightly higher maximum RAM speed of 8400 MHz.

When it comes to the maximum amount of supported memory, the AMD Ryzen AI 9 H 365 can handle up to 256 GB, which is double the maximum supported by the Intel Core Ultra 7 255H, which is limited to 128 GB. Both processors do not support ECC (Error-Correcting Code) memory, meaning neither is suited for applications that require error correction to ensure data integrity.

Overall, the key differences in memory support between the two processors are the maximum RAM speed and the total memory capacity, with the Intel Core Ultra 7 255H supporting faster RAM but the Ryzen AI 9 H 365 having a significantly larger memory capacity.

The AMD Ryzen AI 9 H 365 and Intel Core Ultra 7 255H share similar instruction set support, both offering MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2. These instruction sets are common in modern processors and help accelerate various workloads, from cryptography to multimedia processing.

In terms of multithreading support, the Ryzen AI 9 H 365 supports multithreading, which allows it to execute multiple threads per core and improve parallel processing tasks. The Intel Core Ultra 7 255H, however, does not support multithreading, which limits it to a single thread per core for each task.

Both processors include the NX bit, a security feature that helps prevent certain types of malicious software from running on the system, providing an additional layer of protection against attacks like buffer overflows. Overall, while both processors offer similar instruction sets and security features, the key difference lies in the multithreading capability, which is supported by the Ryzen AI 9 H 365 but not by the Intel Core Ultra 7 255H.
