AMD Ryzen AI 9 HX 375

Manufacturer: AMD

The AMD Ryzen AI 9 HX 375 is a mobile and desktop processor built on a 4nm process node, combining 12 cores and 24 threads with hybrid big.LITTLE architecture to handle a range of computing workloads. It operates within a 28W TDP envelope, with a base configuration of 4 cores at 2GHz and 8 cores at 2GHz, scaling up to a turbo frequency of 5.1GHz for demanding tasks.

On the memory side, the HX 375 supports DDR5 RAM at speeds up to 8000MHz across two channels, with a maximum capacity of 256GB. Its integrated Radeon 890M GPU features 1024 shading units, 64 TMUs, and 32 ROPs, with a boost clock reaching 2900MHz and support for DirectX 12 and OpenCL 2.1. The processor also includes a combined 36MB of L2 and L3 cache, PCIe 4.0 connectivity, and instruction set support covering AVX2, AES, FMA3, and related extensions, with benchmark results of 32916 in PassMark multi-core and 13992 in Geekbench 6 multi-core.

Pros

Supports DDR5 memory at speeds up to 8000MHz with a maximum capacity of 256GB, offering substantial headroom for memory-intensive workloads
The integrated Radeon 890M GPU can drive up to 4 displays simultaneously, making it suitable for multi-monitor setups without a dedicated GPU
24 threads across a hybrid big.LITTLE core layout allows the processor to distribute workloads across efficiency and performance cores
A turbo clock of 5.1GHz gives the chip meaningful headroom for single-threaded tasks that benefit from higher frequencies
Broad instruction set support including AVX2, AES, and FMA3 enables compatibility with a wide range of software and hardware-accelerated operations
Built on a 4nm process with a 28W TDP, the chip fits within a compact thermal budget suited for thin laptop designs

Cons

The multiplier is locked, so there is no option to manually adjust clock speeds for overclocking
ECC memory is not supported, limiting its suitability for applications that require error-correcting memory
Base clock speeds for all core groups start at 2GHz, which is relatively modest before turbo frequencies are reached
The integrated GPU base clock of 400MHz is low, relying heavily on its turbo state of 2900MHz for sustained graphics tasks

Who is this for?

This processor is well-suited for users who need a capable all-in-one chip for thin and light laptops or compact desktop builds, where a 28W TDP and 4nm process help manage heat without requiring aggressive cooling. The 24-thread hybrid core layout makes it a practical fit for content creation, multitasking, and productivity workloads that benefit from parallel processing. Users who need to run multiple displays without a dedicated GPU will also find value here, as the Radeon 890M supports up to four outputs with DirectX 12 and a 2900MHz turbo clock.

Who is this NOT for?

Users looking to push clock speeds beyond stock settings will find this chip unsuitable, as the locked multiplier rules out any overclocking. Workloads that depend on ECC memory for data integrity — such as certain server-side or scientific computing tasks — are not supported by this processor. Additionally, users with demanding GPU workloads such as high-resolution gaming or GPU-accelerated rendering at scale may find the integrated graphics insufficient, given its reliance on turbo states rather than a consistently high base clock.
