In terms of cache, both models come with 8 MB of L2 cache and 16 MB of L3 cache, which should provide ample memory for data handling and improved performance. The Ryzen AI 7 H 350 uniquely supports big.LITTLE technology, enabling more efficient power management by using high-performance cores and energy-efficient cores, while the Ryzen 7 H 255 does not include this feature. Additionally, the clock multiplier differs: the Ryzen 7 H 255 has a multiplier of 38, whereas the Ryzen AI 7 H 350 has a multiplier of 20.

When it comes to PassMark benchmark scores, the AMD Ryzen 7 H 255 scores 28,797, while the AMD Ryzen AI 7 H 350 achieves a slightly lower score of 27,316. This indicates that the Ryzen 7 H 255 has a higher overall performance in multi-threaded tasks.

For single-threaded performance, the Ryzen AI 7 H 350 outperforms the Ryzen 7 H 255 with a score of 3,970, compared to the 3,556 achieved by the Ryzen 7 H 255. This suggests that the Ryzen AI 7 H 350 may have an advantage in tasks that rely heavily on single-core speed.

Overall, the two processors have their strengths, with the Ryzen 7 H 255 excelling in multi-threaded performance, while the Ryzen AI 7 H 350 offers better single-core performance.

The integrated graphics of the AMD Ryzen 7 H 255 and AMD Ryzen AI 7 H 350 differ in several key areas. The Ryzen 7 H 255 is equipped with the Radeon 780M GPU, which has a base clock speed of 800 MHz and can turbo up to 2600 MHz. In contrast, the Ryzen AI 7 H 350 features the Radeon 860M GPU, with a lower base clock speed of 600 MHz but a higher turbo clock speed of 3000 MHz.

Both processors support DirectX 12, OpenGL 4.6, and OpenCL 2.1, ensuring compatibility with a wide range of modern applications and games. Both also support up to 4 displays, providing ample connectivity options for multitasking and high-resolution setups.

When it comes to the GPU's architecture, the Ryzen 7 H 255 offers more powerful graphics hardware with 48 texture mapping units (TMUs), 32 render output units (ROPs), and 768 shading units. The Ryzen AI 7 H 350, while featuring a different GPU model, has fewer TMUs (32), fewer ROPs (8), and fewer shading units (512), which suggests the Ryzen 7 H 255 may deliver more graphical performance overall.

Both the AMD Ryzen 7 H 255 and AMD Ryzen AI 7 H 350 support DDR5 memory with a maximum RAM speed of 7500 MHz and 8000 MHz, respectively. This shows a slight advantage in memory speed for the Ryzen AI 7 H 350, though both products are capable of handling high-speed memory for demanding applications.

Both processors are equipped with two memory channels, enabling efficient memory bandwidth. They also both support a maximum memory amount of 256 GB, providing ample capacity for memory-intensive tasks such as video editing or 3D rendering.

Neither product supports ECC (Error-Correcting Code) memory, meaning they are not designed for applications that require error correction in memory, such as certain types of server or mission-critical systems.

Both the AMD Ryzen 7 H 255 and AMD Ryzen AI 7 H 350 support the same set of instruction sets, including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2. These instruction sets enable the processors to handle a wide variety of workloads, from basic operations to advanced multimedia and cryptographic tasks.

Both processors also support multithreading, allowing them to execute multiple threads simultaneously for improved performance in parallel computing tasks. Additionally, both models have the NX bit feature, which enhances security by preventing certain types of malicious code from executing in non-executable memory regions.

Since the specs for both products in this group are identical, there are no differences between the two in terms of features.
