AMD Ryzen 7 8745HX VS AMD Ryzen AI 7 350

Both the AMD Ryzen 7 8745HX and the AMD Ryzen AI 7 350 share the same broad platform compatibility, supporting both laptop and desktop deployments, offering integrated graphics, full 64-bit support, and a maximum CPU temperature of 100 °C. These shared traits mean neither chip holds an inherent architectural advantage in terms of basic platform flexibility or thermal ceiling.

The most consequential difference in this group is TDP: the Ryzen 7 8745HX is rated at 55W versus the Ryzen AI 7 350's 28W. In practice, this nearly 2x power gap means the 8745HX is designed for systems with robust cooling solutions — think larger gaming or workstation laptops — while the AI 7 350 targets thinner, more power-efficient designs with longer battery life potential. The AI 7 350 also steps ahead in manufacturing process, using a 4 nm node versus the 8745HX's 5 nm, which generally translates to better transistor density and improved power efficiency at equivalent workloads.

On connectivity, the 8745HX supports PCIe 5.0 while the AI 7 350 is limited to PCIe 4.0. This gives the 8745HX a meaningful edge for users pairing the CPU with the latest NVMe SSDs or discrete GPUs that can leverage Gen 5 bandwidth. Overall, the 8745HX has the advantage for high-performance, thermally unconstrained builds, while the Ryzen AI 7 350 holds the edge in efficiency-focused and compact system designs.

The AMD Ryzen 7 8745HX and the AMD Ryzen AI 7 350 differ in several key performance aspects. The Ryzen 7 8745HX features a CPU speed of 8 x 3.6 GHz with a turbo clock speed of 5.1 GHz, offering a substantial boost in high-demand situations. In contrast, the Ryzen AI 7 350 has a more complex CPU configuration, with 4 cores running at 2 GHz and 4 cores running at 2 GHz, along with a turbo clock speed of 5 GHz. While both processors offer 16 threads, the Ryzen 7 8745HX’s higher base and turbo clock speeds might give it an edge in sustained performance.

When it comes to cache, both processors have 8 MB of L2 cache, but the Ryzen 7 8745HX has a larger L3 cache of 32 MB compared to the Ryzen AI 7 350's 16 MB. This larger L3 cache in the Ryzen 7 8745HX could lead to better performance in tasks that rely on rapid access to a larger amount of data.

Another notable difference is the use of big.LITTLE technology. The Ryzen AI 7 350 utilizes this technology, which can improve energy efficiency by dynamically managing performance across different types of cores. The Ryzen 7 8745HX, however, does not use big.LITTLE technology. Additionally, the Ryzen 7 8745HX has an unlocked multiplier, allowing for overclocking, while the Ryzen AI 7 350 does not support this feature. Finally, the clock multiplier for the Ryzen 7 8745HX is 36, while the Ryzen AI 7 350 has a clock multiplier of 20, reflecting the differences in their base clock speeds and performance potential.

The integrated graphics of the AMD Ryzen 7 8745HX and AMD Ryzen AI 7 350 differ in several key areas. Both processors feature a GPU clock speed of 400 MHz, but the Ryzen 7 8745HX is equipped with a Radeon 610M GPU, while the Ryzen AI 7 350 has a Radeon 860M GPU. The Radeon 860M in the Ryzen AI 7 350 benefits from a higher GPU turbo speed of 3000 MHz, compared to the Ryzen 7 8745HX's 2200 MHz.

In terms of execution units, the Ryzen 7 8745HX has 2 execution units, while the Ryzen AI 7 350 has 8, offering a potentially greater capacity for parallel processing tasks. The Ryzen AI 7 350 also has a significantly higher number of shading units, with 512 compared to the Ryzen 7 8745HX’s 128, which can improve graphical performance in demanding applications.

Both processors support up to 4 displays and are compatible with DirectX 12, OpenGL 4.6, and OpenCL 2.1, so there is no difference between the two in terms of graphics API support. Additionally, both processors feature the same number of render output units (ROPs) at 4 and texture mapping units (TMUs) at 8 for the Ryzen 7 8745HX, compared to 8 ROPs and 32 TMUs in the Ryzen AI 7 350, suggesting more advanced texturing and rendering capabilities in the latter.

The AMD Ryzen 7 8745HX and the AMD Ryzen AI 7 350 offer similar memory configurations, but with some key differences. Both processors support DDR5 memory, with the Ryzen 7 8745HX having a maximum RAM speed of 5200 MHz, while the Ryzen AI 7 350 supports a faster RAM speed of 8000 MHz. This higher memory speed in the Ryzen AI 7 350 can potentially improve overall memory bandwidth and system performance in tasks that require fast data access.

Both processors are equipped with 2 memory channels, which helps in improving memory throughput. In terms of maximum supported memory, the Ryzen 7 8745HX supports up to 64 GB of RAM, while the Ryzen AI 7 350 can handle a significantly higher 256 GB. This difference in maximum memory capacity could make the Ryzen AI 7 350 more suitable for workloads that demand large amounts of memory, such as virtual machines or memory-intensive applications.

Neither processor supports ECC memory, which means they are both designed for general consumer use rather than applications requiring error-correcting code memory for added stability.

The AMD Ryzen 7 8745HX and the AMD Ryzen AI 7 350 share identical features in terms of instruction sets and capabilities. Both processors support a wide range of instruction sets, including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, ensuring compatibility with modern software and providing enhanced performance for multimedia, encryption, and other computational tasks.

Both processors also utilize multithreading, allowing them to handle multiple threads simultaneously for improved multitasking and performance in parallel workloads. Additionally, both processors have the NX bit, which is a security feature that helps protect against certain types of malicious software.

Since all the features are the same for both the Ryzen 7 8745HX and the Ryzen AI 7 350, there are no differences in this spec group between the two products.
