Setup Notes and Platform Analysis
The video below presents the entire gamut of available options in the BIOS of the 4X4 BOX-7735U/D5. Of particular interest is the 'CPU Operating Mode' under 'Advanced > CPU Configuration'. It is set to 'Normal' by default, corresponding to a TDP of 28W. Altering it to 'Performance' sets the fan speed to maximum irrespective of the actual load, but ekes out extra performance by pushing up the TDP to 42W.
The system is equipped with dual LAN ports backed up by Realtek controllers. Similar to previous 4X4 BOX systems, the 1GbE link comes with DASH support to make it easy for IT departments to deploy and manage the system with an out-of-band management interface. This support is disabled by default.
The block diagram below presents the overall high-speed I/O distribution.
The HDMI 2.1 port is actually driven from one of the DisplayPort outputs of the SoC with a Realtek RTD2175 protocol convertor on the board. The two Type-C ports in the front panel are both USB4 driven from the SoC in the same manner - a Realtek RTS5452E power delivery controller and a Kandou Technologies KB8002 retimer. One of the unfortunate aspects here is that this retimer doesn't support USB 3.2 Gen 2x2 (20 Gbps) operation, but all other interesting modes including full PCIe tunneling are supported. The rest of the platform components (including the network controllers, audio codec, etc.) are similar to the one in the previous 4X4 BOX series.
In today's review, we compare the 4X4 BOX-7735U/D5 and a host of other UCFF systems based on processors with TDPs ranging from 15W to 40W.

Looking at the AMD specs for the CPU, it supports ECC if the platform does. Does the platform support ECC?A fanless variant (possibly with a lower power limit and a larger box) would be nice for the desktop, but (I guess) also for a number of industrial environments.

Disappointed with AV1 decoding.AMD needs to fix that ASAP.

For the benchmarks I could easily reproduce*, the figures for this PC are very similar to those for the (considerably more expensive, and probably much quieter) base-model M2 Pro Mac mini (10 CPU cores, 16 GPU cores, 16GB RAM). The Mac mini is prettier, has more Thunderbolt ports, and does not need a power brick, but has only one 1G ethernet port. ($100 more gets you 10G, which also enables very minimal remote power management.)* Crossmark, Cinebench, Handbrake, Jetstream (Firefox), Speedometer (Firefox), WEBXPRT4 (Firefox), Aztec Ruins, Wild Life (M2 performance notably better on those last two).

Thanks! exactly why i would get this over a mac minimeacupla - Saturday, April 8, 2023 - link
The size of a mac mini is also considerably larger than a NUC with its power brick.sjkpublic@gmail.com - Sunday, April 9, 2023 - link
MAC Mini you buy it that is it. Limited memory and brain damage. The only positive with a MAC mini is China and Twain going to be toast.sjkpublic@gmail.com - Sunday, April 9, 2023 - link
Huh? They announced this 2 months ago on this web site. And now they announce it again? And I still could not buy it. So I bought something else. Way behind the curve!!!!!!!!!!!!!!!!sjkpublic@gmail.com - Sunday, April 9, 2023 - link
I got a 7735HS for $500. That is the current price of a ASROCK 4800U which I also own (great box). My guess is the price for the ASROCK 7735U will be at least $700. ASROCK dropped the ball.sjkpublic@gmail.com - Sunday, April 9, 2023 - link
USB4 seems to only work best with Win11+. When I use the Win10 22h2 or WS2022 the USB4 driver knocks out the other USB gen 3.2 C port. Would like a post by anyone using Linux or WS2022 and having all the USB ports working.Its Toasted - Monday, April 10, 2023 - link
Dear anandtech team,I would like to thank you very much for the detailed and comprehensive Mini-PC tests. Based on your tests I decided to buy the ASRock Industrial 4X4 BOX-5800U and I am very satisfied with it and I am very grateful to you.
Best regards
Its Toasted
