Geekom A9 Max Review: Single Channel iGPU Analysis

The cruelest bottlenecks are the ones you can hold between two fingers. In a mini PC, one lonely memory module can make an integrated GPU feel like it showed up to a bank job with a bicycle getaway. The Geekom A9 Max review cycle is a tidy reminder that AMD’s APU is only half the graphics story, because the iGPU has to drink through the memory straw the system builder gave it. That is the useful hardware lesson hiding under the product chatter. Buyers see Ryzen AI 9, Radeon graphics, compact metal chassis, and a tidy desk footprint, then assume the silicon is the whole plot. It is not. Memory configuration is the getaway driver, the vault code, and occasionally the guy who forgot to cut the alarm wire.

KitGuruTech Found the Trap Door in the A9 Max Upgrade

KitGuruTech framed its 2026 Geekom A9 Max review as a surprise investigation rather than a routine spec bump. According to KitGuruTech, the 2026 model looked similar to the 2025 version, with the main change being a CPU upgrade from AMD Ryzen AI 9 HX 370 to HX 470. The reviewer expected perhaps a 5% boost, but instead found performance was "dramatically worse," then pointed viewers to the root cause and a discussion around the memory situation. That is the part worth underlining with a soldering iron. Integrated GPUs do not have their own big pool of dedicated graphics memory sitting beside them like a discrete card does. They lean on system RAM, so channel count is not a cosmetic line item, it is the width of the road between the GPU and its lunch. Put the iGPU on a single channel and you have built a beautiful little toll booth in front of a very impatient graphics engine. KitGuruTech’s chapter list also says gaming performance was hit hard, while the same review notes Geekom responded and that there were no other design changes beyond another SSD change. That makes the story more useful than a simple faster or slower verdict. If a CPU upgrade coincides with weaker graphics results, the first suspect should not always be AMD’s die. Sometimes the culprit is the memory map, standing in the hallway wearing a fake mustache.

TechPowerUp Shows Why

the Chassis Makes the Miss Easy to Overlook TechPowerUp’s Geekom A9 Max review describes the machine as a compact mini PC with a premium feel, a sturdy metal chassis, and dimensions of 135 x 132 x 46 mm. TechPowerUp also places it around $1,000 and notes Geekom’s broader push in compact desktops, including systems positioned as alternatives to Intel’s discontinued NUC line, which ended in 2023. That is exactly the kind of product where the spec sheet can seduce you before the board layout gets a vote. Small systems are wonderful little thermodynamic kompromat files. Every cubic millimeter has a job, every vent is negotiating with dust, and every upgrade slot is a treaty between performance and packaging. The A9 Max is built to look serious on a desk, but the review lesson is that physical memory population still matters after the marketing photos are cropped. If the RAM arrangement kneecaps the iGPU, the chassis cannot charm its way out of the benchmark. Let’s talk about what they did not mention in the keynote, because this is where APUs live or stall. An iGPU is not merely asking for capacity, it is asking for bandwidth, and channel configuration changes how much traffic can move at once. Capacity is the warehouse. Channel width is the loading dock. A giant warehouse with one loading bay is how you get a forklift traffic jam with RGB lighting.

Notebookcheck and Adamant IT Point to the Buyer’s Real Checklist

Notebookcheck says the A9 Max is launching as a high end mini PC in a 2026 edition based on AMD’s current Gorgon Point platform, with a focus on upgradeability. Adamant IT’s Geekom A9 Max Mini PC Review listing, posted on 8 Jun 2026, also shows AMD HX 370 and HX 470 configurations in the purchase links. Those details matter because a buyer is not just choosing a processor badge. They are choosing a configuration that may decide how much of the iGPU they actually get to use. Upgradeability is the friendly trapdoor in this story. If memory is socketed and accessible, a bad channel configuration can be corrected, but only if the buyer knows to check. For an APU machine, two smaller matched modules can be more valuable than one larger module, because the graphics engine wants parallel access more than it wants a lonely banquet table. The practical move is simple: before buying, confirm not only how much RAM is installed, but how it is populated. This is especially important for small form factor builders, lab users, and anyone eyeing a mini PC as a quiet desktop replacement. A review score may describe one tested configuration, not every possible SKU on a storefront. If one listing says HX 370 and another says HX 470, that still does not answer the memory channel question. The CPU name is the movie poster. The RAM configuration is the plot twist in act three.

KitGuruTech’s Older A9 Max Context Makes the Lesson Stick KitGuruTech’s 2025 A9

Max review described that earlier Geekom system as using AMD’s Ryzen AI 9 HX 370 with Radeon 890M iGPU, 2TB of NVMe storage, and 32GB of DDR5 memory in a metal chassis less than 1L in volume. In the later 2026 review, KitGuruTech says the main shift was the move from HX 370 to HX 470. That comparison is why the memory issue lands so cleanly: the newer silicon label alone did not guarantee better real world graphics behavior. For readers, the takeaway is not that the A9 Max is doomed, or that AMD APUs are secretly fragile. The takeaway is that integrated graphics are systems engineering, not sticker engineering. The memory subsystem, firmware choices, cooling behavior, and SKU configuration all decide whether the iGPU gets a clean runway or a hallway full of folding chairs. So if you are shopping for a mini PC, do the unglamorous thing before the checkout button. Ask whether the RAM is installed in dual channel, look for reviews that state the tested memory configuration, and treat vague listings like a connector with no pinout. The next wave of compact AMD systems will keep getting more interesting, but the old board level truth still applies: bandwidth is not optional, it is the voltage rail of graphics performance.
