– Dual-channel RAM dramatically boosts performance: adding a second, identical RAM module enables fast dual-channel memory, increasing overall system bandwidth and responsiveness, especially benefiting integrated graphics.
– Integrated GPU gains are substantial: the AMD Radeon 890M iGPU benefits most from higher memory bandwidth, with smoother gaming, faster frame times, and improved graphics-accelerated app performance.
– CPU gains are notable but variable: Ryzen AI 9 HX 470 shows a measurable, though workload-dependent, 5–15% performance uplift when a second RAM module is present.
RAM will remain an important cost factor when purchasing or upgrading modern PCs and mini PCs in 2026. Fast DDR5 modules in particular are still comparatively expensive compared to previous memory standards, which is why many systems are often only supplied with a single RAM module or are initially used in a smaller configuration. However, this can have a noticeable negative impact on overall performance, especially in compact devices with powerful integrated graphics.
RAM configurations and system performance
Modern processors are increasingly relying on high memory bandwidths to efficiently supply the CPU and integrated GPU. If a system only works in single-channel mode, only part of the possible bandwidth is available. The faster dual-channel mode is only activated with a second memory module. This is particularly beneficial for integrated graphics units that do not have their own video memory and access the main memory directly. At the same time, the general system performance can also improve, for example with multitasking, productive applications, or computing-intensive tasks. The importance of the right RAM configuration for actual performance therefore quickly becomes apparent, especially with powerful mini PCs. Using the recently tested Minisforum AI X1 Pro as an example, we show the influence a second RAM module can have on the overall performance of the system.
Dual-channel gains in practice
The Minisforum AI X1 Pro gains noticeably in performance by installing a second RAM module. Only with two identical memory modules does the system work in fast dual-channel mode, which significantly increases the available memory bandwidth. The integrated graphics unit in particular benefits significantly from this, while the AMD Ryzen AI 9 HX 470 itself also records a small increase in performance. Modern Ryzen CPUs are heavily dependent on a fast memory connection, as data can be transferred faster between the RAM and processor. In practice, this leads to shorter loading times, smoother multitasking, and an overall higher system response. CPU performance can increase by around 5 to 15 percent, depending on the software, particularly with computing-intensive applications. The AI X1 Pro therefore only reaches its maximum performance with a dual-channel RAM configuration, as can be seen from our comparative values.
Impact on graphics and gaming
The integrated AMD Radeon 890M in the Minisforum AI X1 Pro benefits enormously from a second RAM module. Only with two DDR5 memory modules installed does the iGPU have the full memory bandwidth at its disposal. As integrated graphics units do not have their own video memory and instead access the RAM, the higher bandwidth has a direct effect on graphics performance. Games run more smoothly, frame times improve and graphics-accelerated applications also respond noticeably faster. Depending on the title and resolution, performance increases of up to over 100 percent are possible.
