AMD Ryzen 7 8840HX VS AMD Ryzen AI 7 350

Both the AMD Ryzen 7 8840HX and the AMD Ryzen AI 7 350 share the same broad positioning — they are designed for both laptop and desktop form factors, include integrated graphics, support 64-bit computing, and top out at the same maximum CPU temperature of 100 °C. These shared traits mean neither chip has a fundamental architectural advantage in terms of platform flexibility or basic capability.

The most significant differentiator in this group is Thermal Design Power (TDP): the 8840HX is rated at 55W, while the Ryzen AI 7 350 comes in at just 28W. In practice, the 8840HX's higher TDP means it can sustain greater performance but demands more robust cooling and draws considerably more power — making it better suited for thicker, high-performance laptops or desktops where thermals are not a constraint. The Ryzen AI 7 350's lower TDP makes it a stronger fit for slim, fanless, or battery-sensitive designs. On the manufacturing side, the Ryzen AI 7 350 is built on a 4 nm process versus the 8840HX's 5 nm, which generally translates to improved transistor density and energy efficiency per operation — reinforcing its efficiency-focused profile.

The 8840HX also supports PCIe 5.0 versus the Ryzen AI 7 350's PCIe 4.0, giving it a meaningful edge for users pairing the chip with next-generation NVMe storage or discrete GPUs that can leverage PCIe 5.0 bandwidth. Overall, the 8840HX holds the advantage for raw, sustained performance workloads and modern I/O throughput, while the Ryzen AI 7 350 has a clear edge in power efficiency and process technology — making the right choice highly dependent on the target use case.

The AMD Ryzen 7 8840HX and AMD Ryzen AI 7 350 differ significantly in several performance aspects.

This means that the Ryzen 7 8840HX potentially has a higher base clock speed, with more cores working at a consistent speed, offering potential for greater parallel processing power.

The Ryzen 7 8840HX also offers a higher turbo clock speed of 5.1 GHz, while the Ryzen AI 7 350 reaches a maximum turbo speed of 5 GHz, so both processors are quite close in terms of peak performance during intensive tasks. However, the Ryzen 7 8840HX has an unlocked multiplier, giving users more flexibility for overclocking, whereas the Ryzen AI 7 350 does not support this feature.

When it comes to cache, the Ryzen 7 8840HX boasts a larger L2 cache of 12 MB and L3 cache of 64 MB, compared to the Ryzen AI 7 350’s 8 MB L2 cache and 16 MB L3 cache. This means the Ryzen 7 8840HX is equipped with more on-chip memory for faster data access. Additionally, the Ryzen AI 7 350 employs big.LITTLE technology, which is not present in the Ryzen 7 8840HX, potentially offering different power efficiency optimizations in multi-core workloads.

When comparing the PassMark benchmark results, the AMD Ryzen 7 8840HX outperforms the Ryzen AI 7 350 in both overall and single-core performance. The Ryzen 7 8840HX has a total PassMark result of 45,268, while the Ryzen AI 7 350 scores 34,459. This indicates a notable performance gap in multi-core workloads between the two processors.

In terms of single-core performance, the difference is smaller, with the Ryzen 7 8840HX scoring 3,862 and the Ryzen AI 7 350 slightly ahead at 3,878. This suggests that the Ryzen AI 7 350 has a marginally better single-core performance in specific tasks, but overall, the Ryzen 7 8840HX leads in multi-core tasks, as reflected in the higher total PassMark result.

Both processors perform well, but the Ryzen 7 8840HX stands out in terms of overall multi-core performance, while the Ryzen AI 7 350 holds a slight edge in single-core tasks.

The integrated graphics of the AMD Ryzen 7 8840HX and AMD Ryzen AI 7 350 show distinct differences in several key areas. Both processors feature a GPU clock speed of 400 MHz, but the GPU turbo speeds differ significantly. The Ryzen 7 8840HX has a turbo speed of 2,200 MHz, while the Ryzen AI 7 350 can boost up to 3,000 MHz, suggesting that the latter may offer better performance during demanding graphics tasks.

In terms of GPU execution units, the Ryzen 7 8840HX has 2 units, while the Ryzen AI 7 350 has 8 units. This larger number of execution units in the Ryzen AI 7 350 may contribute to more parallel processing power for graphics rendering, potentially enhancing performance in certain tasks.

The Ryzen 7 8840HX uses the Radeon 610M GPU, while the Ryzen AI 7 350 is equipped with the Radeon 860M GPU. Both processors support DirectX 12 (with the Ryzen 7 8840HX supporting DirectX 12 Ultimate) and have the same OpenGL version (4.6) and OpenCL version (2.1). The Ryzen AI 7 350 also has more texture mapping units (TMUs) at 32, compared to the Ryzen 7 8840HX’s 8 TMUs, which may result in more detailed texture rendering. Additionally, the Ryzen AI 7 350 has 8 render output units (ROPs), while the Ryzen 7 8840HX has 4, suggesting potentially better output rendering capabilities in the Ryzen AI 7 350.

The AMD Ryzen 7 8840HX and AMD Ryzen AI 7 350 both support DDR5 memory and utilize two memory channels. However, they differ significantly in terms of maximum RAM speed and capacity. The Ryzen 7 8840HX supports a maximum RAM speed of 5,200 MHz, while the Ryzen AI 7 350 can reach up to 8,000 MHz, indicating that the latter can handle faster memory speeds for potentially better performance in memory-intensive tasks.

When it comes to memory capacity, the Ryzen 7 8840HX supports up to 64 GB of memory, whereas the Ryzen AI 7 350 can handle up to 256 GB of memory, offering significantly more headroom for demanding workloads that require large amounts of RAM.

Both processors do not support ECC (Error-Correcting Code) memory, meaning neither offers built-in protection against certain types of memory errors, which might be important for specific professional or high-reliability applications.

The AMD Ryzen 7 8840HX and AMD Ryzen AI 7 350 share identical features when it comes to instruction sets, multithreading support, and the NX bit. Both processors support the same set of instruction sets, including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, which allows them to handle a wide variety of tasks efficiently. Additionally, both processors support multithreading, enabling them to handle multiple tasks simultaneously, enhancing overall performance in multi-core workloads.

Both CPUs also have the NX bit, which is a security feature that helps protect against certain types of malware by preventing the execution of code in certain areas of memory. This feature is common in modern processors and is included in both the Ryzen 7 8840HX and Ryzen AI 7 350, ensuring they both benefit from this security enhancement.

As there are no differences between these two processors in the features listed here, they offer the same capabilities in these areas.
