AMD Ryzen AI 5 Pro 340 VS AMD Ryzen AI 7 Pro 350

At the general platform level, the AMD Ryzen AI 5 Pro 340 and AMD Ryzen AI 7 Pro 350 are virtually identical twins. Both processors share the same 4 nm semiconductor process, a 28W TDP, a peak CPU temperature ceiling of 100 °C, PCIe 4.0 support, integrated graphics, and full 64-bit capability. Both are also designed for the same deployment contexts — laptop and desktop platforms — differing only in the order those form factors are listed, which carries no practical significance.

The shared 28W TDP is worth noting: this is a balanced envelope typical of modern thin-and-light business laptops and compact desktops, meaning neither chip is positioned as a high-wattage performance monster nor an ultra-low-power efficiency part. Paired with the 4 nm node, both should deliver competitive performance-per-watt for their class. The 100 °C thermal ceiling is standard for AMD mobile/desktop processors and indicates that the chips can sustain operation up to that point before throttling, putting the burden of differentiation on cooling solutions rather than the silicon itself.

Based strictly on the general info specs provided, these two processors are in a complete tie. There is no differentiator in this group — same process node, same power envelope, same platform support, same thermal limits. Any meaningful distinction between the Ryzen AI 5 Pro 340 and Ryzen AI 7 Pro 350 will need to come from other specification groups such as CPU cores, clock speeds, or AI engine throughput.

The core count gap is the headline story here. The Ryzen AI 7 Pro 350 fields 8 cores and 16 threads against the Ryzen AI 5 Pro 340's 6 cores and 12 threads — a 33% advantage in parallelism that translates directly into faster rendering, better multitasking, and stronger performance in workloads that scale across threads. The Pro 350 also edges ahead on peak single-core burst speed with a 5 GHz turbo clock versus 4.8 GHz on the Pro 340, meaning it is faster in both lightly-threaded and heavily-threaded scenarios simultaneously.

The cache picture is more nuanced and worth unpacking. The Pro 340 carries a larger L3 cache of 16 MB compared to the Pro 350's 8 MB, but the Pro 350 counters with a substantially larger L2 cache of 16 MB versus just 6 MB on the Pro 340. Since L2 cache sits closer to each core and operates at lower latency than L3, the Pro 350's configuration tends to favor workloads with high per-core data locality — such as gaming loops and latency-sensitive compute tasks — while the Pro 340's deeper L3 pool can benefit large working-set workloads like database queries or certain simulation tasks. Neither architecture is universally superior here; the tradeoff depends on use case.

Taking the full picture into account, the Ryzen AI 7 Pro 350 holds a clear performance edge in this group. More cores, higher turbo frequency, and a more aggressive L2 cache make it the stronger chip for the majority of demanding workloads, and no single spec on the Pro 340 is compelling enough to close that gap.

The PassMark results put hard numbers behind what the spec sheet already suggested. In the multi-threaded benchmark, the Ryzen AI 7 Pro 350 scores 24,010 against the Ryzen AI 5 Pro 340's 19,500 — a gap of roughly 23%. In practical terms, that margin is meaningful: users running video exports, compilation jobs, or any parallelized professional workload will notice a consistently faster machine in the Pro 350.

The single-core scores tell a tighter story. The Pro 350 registers 3,941 versus 3,830 for the Pro 340 — a difference of just under 3%. For everyday tasks like browsing, document editing, or launching applications, where only one or two cores are typically engaged, both chips will feel essentially identical. The single-core gap is too narrow to be perceptible in real-world use.

The Ryzen AI 7 Pro 350 is the clear winner in this group. Its multi-threaded advantage is substantial and consistent with its higher core count, while the marginal single-core lead is a bonus rather than a deciding factor. The Pro 340 remains competitive for light workloads, but users whose tasks regularly push multiple cores — and most professional workloads do — will extract meaningfully more throughput from the Pro 350.

Both processors carry Radeon integrated graphics, but they are not the same silicon. The Ryzen AI 7 Pro 350 pairs with the Radeon 860M, while the Ryzen AI 5 Pro 340 gets the Radeon 840M — a step down in AMD's iGPU stack. The most measurable difference in this group is peak GPU clock speed: the 860M boosts to 3,000 MHz versus 2,900 MHz on the 840M, a roughly 3.4% advantage. On its own that gap is modest, but combined with whatever architectural differences exist between the 840M and 860M model tiers, it positions the Pro 350 as the stronger choice for graphics-dependent tasks like light gaming, GPU-accelerated creative apps, and compute workloads offloaded to the iGPU.

Where the two chips are fully identical is in API and display support. Both deliver DirectX 12, OpenGL 4.6, and OpenCL 2.1, ensuring compatibility with the same ecosystem of games, professional applications, and GPU-compute frameworks. Support for up to 4 simultaneous displays is also shared, making either chip a capable foundation for multi-monitor productivity setups without a discrete GPU.

The Ryzen AI 7 Pro 350 holds a narrow but real graphics edge here by virtue of its higher-tier Radeon 860M and faster GPU turbo clock. For users who rely solely on integrated graphics for anything beyond basic desktop tasks, that advantage is worth noting. For pure productivity or display-output use cases, however, both chips are effectively equivalent.

Memory is one area where choosing between these two processors makes absolutely no difference. The Ryzen AI 5 Pro 340 and Ryzen AI 7 Pro 350 share an identical memory specification across every dimension: DDR5 support, a maximum RAM speed of 8,000 MHz, a dual-channel configuration, a ceiling of 256 GB of addressable memory, and full ECC support.

The highlights are worth contextualizing. DDR5 at 8,000 MHz is at the high end of what current platforms support, which benefits both integrated graphics throughput and CPU performance in memory-sensitive workloads. The 256 GB maximum capacity is unusually generous for processors in this class, making either chip viable for memory-intensive professional workloads like large virtual machines, in-memory databases, or extensive data analysis pipelines. ECC support — which detects and corrects single-bit memory errors — signals the Pro-tier business focus of both chips, as this feature matters for environments where data integrity is non-negotiable.

This group is a complete tie. No differentiation exists between the two processors on any memory specification, so this category should have zero influence on a purchase decision. Users should look to the performance and benchmark groups, where the Pro 350 establishes its lead, to guide their choice.

From a feature-set standpoint, the Ryzen AI 5 Pro 340 and Ryzen AI 7 Pro 350 are indistinguishable. Both support the same instruction set extensions — including AVX2 and FMA3, which are the most practically significant on the list — along with multithreading and the NX bit security feature.

The shared AVX2 support is the most meaningful item here for professional users, as it enables wide 256-bit SIMD operations that accelerate workloads like scientific computing, image processing, and certain machine learning inference tasks. AES hardware acceleration is equally relevant for enterprise deployments, ensuring that encryption and decryption operations — ubiquitous in secure business environments — impose minimal CPU overhead. The NX bit, meanwhile, is a foundational hardware security feature that helps prevent a class of memory-based exploits; its presence is expected in any modern business-oriented processor.

This group is a complete tie with no differentiator between the two chips. Software compatibility, security posture, and SIMD acceleration capabilities are identical across both processors, so features alone offer no basis for choosing one over the other. The decision remains anchored in the performance and benchmark groups, where the Pro 350 holds its established lead.
