ASRock Brings Zen 2 NUC : 4X4 BOX-4800U Renoir Mini-PC Reviewed
by Ganesh T S on November 25, 2020 11:00 AM ESTHTPC Credentials - I
The ASRock 4X4 BOX-4800U comes with four display outputs. All of them support 4Kp60, with the HDMI port providing support for HDR as well as HDCP 2.2. Unfortunately, UHD Blu-rays can't be played back on the system, though HDCP 2.2 enables other protected content to be displayed at full resolution. The system also supports HD audio bitstreaming over the HDMI port.
Our evaluation of the 4X4 BOX-4800U as a HTPC was done using the native HDMI output connected to a TCL 55P607 4K HDR TV via a Denon AVR-X3400H AV receiver.
We tested out various display refresh rates ranging from 23.976 Hz to 59.94 Hz. Of particular interest is the 23.976 Hz (23p) setting, which Intel used to have trouble with in the pre-Broadwell days.
The gallery below presents screenshots from the other refresh rates that were tested. The system has no trouble maintaining a fairly accurate refresh rate throughout the duration of the video playback.
Our HTPC testing with respect to YouTube had been restricted to playback of a 1080p music video using the native HTML5 player in Firefox. The move to 4K, and the need to evaluate HDR support have made us choose Mystery Box's Peru 8K HDR 60FPS video as our test sample moving forward. On PCs running Windows, it is recommended that HDR streaming videos be viewed using the Microsoft Edge browser after putting the desktop in HDR mode.
The system is supposed to support 4Kp60 VP9 Profile 2 playback, and MS Edge automatically gets the correct encode from the YouTube servers. However, the playback was punctuated by frequent dropped frames as shown in the statistics segment of the above screenshot.
Various metrics of interest such as GPU usage and at-wall power consumption were recorded for the first four minutes of the playback of the above video. The numbers are graphed below.
The GPU and decoder utilization numbers spiking close to 100% in the above graph explains the dropped frames. Interestingly, as we shall see in the next section, local playback fo VP9 Profile 2 videos didn't result in any issues.

I've been drinking, it's 1900 and I've only eaten breakfast today so bear with me.I'm just astonished that we're now using 64GB DDR4 to eliminate any chance bottlenecking. My last system had 24GB DDR3 and I'm now on 16GB DDR4 with no memory concerns.
As for *hic* SFF HTPC use, AMD has driver issues. I once said to a guy who deals in GPGPU stuff that "I don't have enough experience in drivers or coding to be able to say whether AMD's drivers are good or bad" and his response was "that's the same problem AMD have". If I'm using a PC for relaxing, having to debug or troubleshoot is not ideal. It's a shame, as noted in the conclusion here, that QA is often done on Intel systems and AMD don't get a look-in. Hopefully, as AMD become profitable and more performant they'll be able to convince people to QA on their hardware as well.
They definitely need to sort out their drivers and assess the OEM support for other hardware. It's a sad fact that, since I dropped Intel for AMD (both CPU and GPU), I've had more crashes in a month than in years of Intel/Nvidia systems. I've lost more time to lost work than when I was using Windows 98 and CTRL+S after every change is back to being automatic.
A few months ago I was trying to get 4K working on Netflix and their website specified only Nvidia card support or Intel iGPU decode support. Their support staff had never heard of the issue and so I went through the codecs supported by AMD and pointed out at least their hardware spec page should mention AMD once??? The guy couldn't help so he took it as a comment to escalate higher.
/ramble. I need crisps.

Got a secondary AMD rig that is 10+ years old and stays online for weeks at a time without a crash.Still runs games just fine, the more modern titles that are heavier threaded tend to run much better on the old Phenom 2 x6 and paired up with the Radeon RX 580 is a pretty capable 1080P rig.
Will upgrade it when it's useless.

$900 is a bit too rich for my blood.BTW, what happened to the latest RTX 3xxx review? Did you guys give up on it?

Apparently you didn't get the memo.fcth - Friday, November 27, 2020 - link
No explanation as to the delay (originally it was related to the fires in California, but it sounded like they were past that), but Ryan said a couple days ago that they are still getting caught up: https://twitter.com/RyanSmithAT/status/13317467171...damianrobertjones - Wednesday, November 25, 2020 - link
...and Intel's driver support for Intel Nucs is hardly anything to scream about.dontlistentome - Wednesday, November 25, 2020 - link
Took Intel an age (over a year) to fix the BIOS updater on systems with Bitlocker - would fail to suspend the encryption so you'd be left with a machine that wouldn't boot, with a locked drive. Hope you kept the recovery key somewhere accessible.Samus - Thursday, November 26, 2020 - link
OMG I remember that bug, the worst part was there was no way to clone a drive to upgrade the SSD because you couldn't suspend bitlocker so you had to decrypt the drive which takes hours in some cases. 3-4 hour project just to upgrade an SSD...Yorgos - Thursday, November 26, 2020 - link
It took intel 3 or 4 years to fix the N2230 driver on linux.bananaforscale - Thursday, November 26, 2020 - link
I remember when Atoms first came and the NM10 chipset. It had crap support on Linux (didn't support resolutions beyond 800x600 for a while). Then there's Asus Transformer Book that has Intel hardware that's only supported under 32 bit Windows, so no upgrading to 64 bit (even if it would've been a bit silly in that particular case as it only had 2GB RAM). Linux is right out.
