ZOTAC’s Streaming Mini-PC, the MI553B, with Integrated AVerMedia Capture Cardby Ian Cutress on January 22, 2019 4:00 PM EST
With the advent of streaming video games online being a core market for computer hardware manufacturers, a new initiative was announced at TwitchCon 2018 to develop smaller form factor PCs to function as the streaming hardware, alleviating some of the workload for large gaming machines. One of the first models was on display at Zotac’s CES Booth, with the MI553B featuring a mobile processor and a built-in capture card.
The system doesn’t look too flash if I’m honest, although Zotac said they were going through the stages of the design to make sure it’s sufficiently quiet. But the goal is to make sure the system is out of the way and just works, so it comes pre-loaded with all the relevant software from AVerMedia and Steamlabs' fork of OBS (which is like OBS, but built up from a standard code base by a different company to OBS).
Inside is a Core i5-7300HQ, a quad core 45W mobile chip with a base frequency of 2.50 GHz and a turbo frequency of 3.30 GHz. It uses the integrated graphics of the chip for display, but has a HDMI 4K30 input from the AVerMedia CN311-H M.2 capture card in order to manage the output of the gaming PC. Zotac might sell this unit as a barebones, however the configuration they had was with 8 GB of DDR4 memory and a 120GB M.2 SSD.
Zotac did ask us if using a 4K60 capture card would be preferable for this market, although they did note that AVerMedia’s 4K60 card is a significant price step above the 4K30 card. Any opinions on this in the comments will be passed on to Zotac.
As for this unit, Zotac said that pricing was still being decided, along with the design, although they hope to have it on market in early Q2.

imaheadcase - Tuesday, January 22, 2019 - linkI would think considering the market this is going for, most people will have decent PC to do 4k60 in all but the demanding game. I mean just looking at games being streamed most can do 4k60 right now because not actually demanding games. The market they are going to sell is not going to care if a few hundred more than the 4k30....especially if the price on the 30 is not even known at launch so most thing its a normal price.
jordanclock - Tuesday, January 22, 2019 - linkIf this is aimed at streamers, than 4K anything is overkill. Streaming platforms simply don't offer the bitrates to provide high quality 1080p60, let alone 4K60.
wolrah - Tuesday, January 22, 2019 - linkMany streamers will record a high quality version of their broadcast that they can post to Youtube and/or grab highlights from. I agree that streaming live at more than 1080p30/720p60 is mostly pointless due to bitrate restrictions but it you're at the point of having a dedicated streaming PC you're likely interested in capturing and recording at a higher rate.
XelaChang - Tuesday, January 22, 2019 - linkNot true at all.
I having been watching amazing 1440p60 streams by SaintSam on youtube - https://www.youtube.com/watch?v=bofDEob1h28
Rocket321 - Tuesday, January 22, 2019 - linkI'm assuming the point of this box is to pair it with a separate gaming PC running a dGPU, in which case this whole other PC just captures the video, encodes, and streams. Is a 2nd PC really necessary given the capabilities of QuickSync and other hardware encoders? My skylake i5 is able to transcode bluerays at 1080p at >60fps by using QSV, but the CPU usage is still pretty high 70-90% so that doesn't leave much for playing a game. I would think it makes more sense to buy a suitably powerful gaming PC with enough CPU cores to also handle streaming at the same time.
On the other hand, if 4k60 streaming is a necessity, then a box like this likely becomes necessary, which may be the whole point to begin with.
wolrah - Tuesday, January 22, 2019 - linkThere is still an impact on performance. It's generally low, but it's there.
A separate box has other advantages aside from just performance though. For one, it's input agnostic. Want to stream a console game today? Move a few cords around and go for it.
Another advantage is stability. Games can be buggy and GPU drivers have great power to crash systems. For a streamer trying to make money having the stream go dead because a game crashed the GPU hard is not a good thing. External capture keeps the stream live, showing the crash and your reaction.
A third advantage is compatibility. Some games really don't get along with the way OBS captures video. Workarounds for this are sometimes buggy and almost always cost performance. External capture just works.
zodiacfml - Tuesday, January 22, 2019 - linkLittle idea with streaming but AMD cards can do streaming/recording pretty well. This is definitely for consoles or smartphones
