KAMRUI Hyper H1 (Ryzen 7 7735HS)

Published on August 2, 2026

The KAMRUI Hyper H1 is a compact mini PC built around the AMD Ryzen 7 7735HS, an 8-core, 16-thread Zen 3+ chip that carries Radeon 680M graphics with it. KAMRUI pairs that silicon with soldered LPDDR5-5500 memory, two M.2 2280 slots, a 2.5GbE port, and enough display output to drive three 4K screens at once. It shares its name with KAMRUI’s earlier Ryzen 7 6800H model, but this is a different board: the SO-DIMM slots are gone, the second Ethernet jack is gone, and the memory ceiling is fixed at whatever configuration you order.

Generous Ports and Storage Around Memory You Cannot Change

The chassis is roughly 5.08 inches square and just over two inches tall, 129 x 129 x 51mm, on the standard NUC footprint with a little extra height for airflow. The front face carries the power button, a 3.5mm combo jack, two USB-A 3.2 Gen 2 ports at 10Gbps, and a USB-C 3.2 Gen 2 port that also does DisplayPort 1.4 Alt Mode. The rear holds four USB-A 3.2 Gen 1 ports at 5Gbps, HDMI 2.0, DisplayPort 1.4, the 2.5GbE RJ45 jack, and the barrel connector for the 19V power brick. Seven USB ports is generous for a box this size, and splitting them by speed with the fast pair up front suits external drives. A VESA bracket ships in the box, so the whole thing can disappear behind a monitor.

The Ryzen 7 7735HS is AMD’s Rembrandt-R part: 8 cores, 16 threads, a 3.2GHz base and 4.75GHz boost, 16MB of L3, and Radeon 680M graphics with 12 RDNA 2 compute units clocked to 2200MHz. It is the 2022 Ryzen 6000 mobile silicon rebadged for 2023. Michael’s Tinkerings read the BIOS string and found a 28W sustained limit, well under the 35W to 54W envelope AMD specifies for the chip, and measured the consequences: 1966 in Geekbench 6 single-core against 8755 multi-core, with the wall meter showing 8.2W at idle and 55.2W under a sustained load.

The RAM is LPDDR5-5500 soldered to the board in either a 16GB or a 24GB configuration, with no SO-DIMM slots to fall back on. KAMRUI’s own spec sheet lists it as on-board, and the reviewers who opened the chassis found the same thing. Michael’s Tinkerings measured 35.7 GB/s of bandwidth and 124ns of latency, noting the parts are rated for 6400 MT/s but clocked at 5500. Storage stays open: two M.2 2280 slots taking PCIe 3.0 or 4.0 NVMe drives up to 4TB combined, with SATA M.2 drives explicitly unsupported.

Reviewer Insights

Michael’s Tinkerings on the 28W limit

Michael’s Tinkerings published detailed bench numbers for this machine in April 2026, working from a review unit KAMRUI supplied. On memory, the review is blunt: “There are no SO-DIMM slots. 24 GB is what you have, forever.” Geekbench 6 OpenCL came in at 26009 and Unigine Heaven at the Basic preset averaged 100.5 FPS, both well clear of the Intel integrated graphics in the other mini PCs in the same review set, and Blender’s Classroom scene rendered faster on the 680M than on the CPU. As the review puts it, “This is the first mini PC in the review set where rendering on the iGPU is meaningfully faster than the CPU.”

The review tied the 1966 Geekbench 6 single-core result directly to the 28W configuration, calling it “the review’s most uncomfortable number” and observing that the 7430U in the same set landed at 1953. The same power choice pays off thermally. The review reports a peak Tctl of 85.3 °C during its disk benchmark and describes the machine as effectively inaudible at idle, holding a quiet, stable baseline under sustained work with no fan-ramp cycling. Storage measured 3365 MB/s sequential read and 2254 MB/s sequential write via diskspd, which the review characterizes as PCIe Gen 3 class, and it flags the drive as an undocumented SKU with no advertised TBW figure. Our note on SSD endurance ratings explains why that gap is worth a second thought before you load a machine like this with sustained writes.

The teardown at Retro Handhelds

Ban at Retro Handhelds reviewed the H1 in April 2026 and describes where KAMRUI spent the power budget: “rather than put a lot of the performance into the CPU like most i9 mini PC’s, the power for the H1 was put into the GPU.” On the CPU side, the review places the H1 toward the lower end of the pack against the other machines tested, with single-core and multicore scores both beaten by most of the comparison set. On graphics: “The Radeon 680M graphics are still super performant in 2026 and clear everything else in both Geekbench GPU and my 3DMark tests.”

The review calls opening the case straightforward (flip it, pull the feet, remove the screws, pry past the clips), but inside, “the Kamrui H1 only has the SSD slots,” where older KAMRUI systems offered two SSD slots and two RAM slots. The review scores repairability as a “meh” and closes with a narrow recommendation: “If all you care about is a good deal on GPU performance, get the H1.”

NerdTechy’s desktop-replacement run

NerdTechy ran a 24GB unit as a desktop replacement in April 2026, also on a sample KAMRUI provided. The review is enthusiastic about the footprint (“I went from a full ATX tower footprint to something I can slide behind a monitor and barely notice”) and about the graphics, calling the 680M “the best integrated graphics chip available at this price point and size, full stop.” It describes the chassis as aluminum with a matte finish that does not attract fingerprints, and notes that the dual-fan cooling stays inaudible over ambient room noise during everyday work while ramping up under long gaming or encoding sessions.

On the processor: “Compared to more recent mini PCs running newer Intel or AMD chips, single-core and multi-core scores land on the lower end of the competitive field.” On memory, the review is equally direct that the RAM is soldered and cannot be upgraded later, advising readers to buy the higher-capacity configuration up front if they expect to need it. It also passes along that some longer-term owners have reported reboot errors and kernel problems after several months, describing it as not a widespread pattern but worth knowing.

Buy It for the 680M, and Size the Memory Up Front

An 8.2W idle draw, a fan that stays out of the way, 2.5GbE, and a second M.2 slot add up to a capable home server, media machine, or light content-creation desktop, and the 680M gives it headroom for emulation, older titles, and GPU-accelerated rendering that Intel integrated graphics in the same bracket cannot match. Windows 11 Pro ships preinstalled, and the triple 4K60 output makes it a workable multi-monitor productivity desktop.

If you expect to need more than 24GB of memory at any point in this machine’s life, the soldered LPDDR5 rules it out, because there is no slot to add to. If your workload is single-thread bound (interactive development, heavy spreadsheets, application cold starts), the 28W configuration blunts exactly the part of the chip you would be paying for, and a machine with more thermal budget will feel quicker. Current-generation silicon is off the table here too; the 7735HS is a 2022 architecture carrying a 2023 model number. Comparing it side by side in Starry Hope’s Mini PC Comparison Chart is the fastest way to see where it sits.
