ASRock Industrial has released two new motherboards, 4X4-7735U/D5 and 4X4-7535U/D5, which utilize AMD’s Ryzen 7035 (Rembrandt-R) processor. With its Zen 3+ core and RDNA 2 graphics, the Rembrandt-R is primarily targeted at laptops, but ASRock Industrial has brought his 6nm chip into a more convenient desktop format.
4X4-7735U/D5 and 4X4-7535U/D5 belong to the 4×4 category. With a footprint of 4.09 x 4.02 x 1.4 inches (10.4 x 10.2 x 3.6 cm), it’s slightly larger than the typical Nano-ITX form factor. 4X4-7735U/D5 and 4X4-7535U/D5 have matching specifications and look similar to each other. As you can guess from the model name, the processor choice is the only thing that distinguishes the motherboards.
Considering the timeframe between ASRock’s releases and Simply NUC’s announcements, the 4X4-7735U/D5 and 4X4-7535U/D5 could be the main motherboards for the latter’s Moonstone mini PCs.
The 4X4-7735U/D5 features the Ryzen 7 7735U in an octa-core, 16-thread configuration with clock speeds up to 4.75 GHz. The onboard Radeon 680M features 12 RDNA 2 CUs at up to 2.2 GHz. The 4X4-7535U/D5 is powered by the Ryzen 5 7535U, a hexa-core, 12-thread chip with a 4.55 GHz boost clock. The Radeon 660M incorporates 6 RDNA 2 CUs with a peak clock of 1.9 GHz. Despite the differences, the Ryzen 7 7735U and Ryzen 5 7535U are 28W processors. It’s not as demanding when it comes to heat, but ASRock Industrial still opted for active cooling with his 6nm processor.
A 4×4 motherboard comes with a pair of DDR5 SO-DIMM memory slots. Only DDR5-4800 is supported, but the dual-slot design allows up to 64GB of memory using 32GB DDR5 memory modules. Due to limited space, motherboard storage options are limited. A standard PCIe 4.0 x4 M.2 slot will allow you to use his fast NVMe SSD with 4X4-7735U/D5 or 4X4-7535U/D5. There is also a SATA III port for regular hard drives and SSDs.

With no space for PCIe expansion slots, Rembrandt-R’s integrated RDNA 2 graphics engine drives the 4X4-7735U/D5 and 4X4-7535U/D5 video outputs. This motherboard provides an HDMI 2.1 port supporting up to 7680 x 4320 at 60Hz and DisplayPort 1.4a output at 4096 x 2160 at 60Hz. Users can reuse his two her USB 4.0 Type-C ports for display output and connect up to four monitors.
The 4X4-7735U/D5 and 4X4-7535U/D5 provide two wired Ethernet connections. Realtek RTL8125BG manages 2.5 Gigabit ports and Realtek RTL8111EPV powers standard Gigabit ports with DASH capability. Neither motherboard comes with wireless connectivity, but has an empty M.2 2230 Key E PCIe x1 slot for a wireless card combo.
Motherboards using the Realtek ALC233 audio codec have only one 3.5 mm jack for headphone or microphone. ASRock Industrial put different USB ports on the front and back of the motherboard if the 4X4-7735U/D5 and 4X4-7535U/D5 have such. Nonetheless, the motherboard has two USB 4.0 ports, two USB 3.2 Gen 2 Type-A ports, and two low-speed USB 2.0 ports. Other onboard connectors include DC jacks, USB 2.0 headers, COM headers, and more.
Found by Hardware Detective momomo_us, Newegg already has two motherboards available for pre-order. Retail price for 4X4-7735U/D5 is $6304X4-7535U/D5 is $480. The stated release date for the two motherboards is June 21st, and purchases are limited to one He unit per customer.
