Raspberry Pi 4 Review - Dual displays and upto 4GB of RAM

Vlc does not support hardware decoding and will never support, you need to try it with MPV.

[@thenoseplays2488]

I am almost certain it took you longer to type all this than it would have to simply make a chart in a spreadsheet and show it in the video. That said, thanks anyways.

[@GaryExplains]

@@thenoseplays2488 For sure it did. I just didn't think people wanted such detailed reporting on the performance. I assume most people would be happy with my conclusion that it is 3x faster. The funny thing is that in the past when I included such details there were loads of complaints about why am I including all this synthetic benchmark stuff. I just can't win!

[@soragranda]

Well, three times faster is completely fine, I bet some people were expecting more (I saw some getting really excited for it on Spanish forums, the hype I suppose).

[@jonathanstein6056]

Screaming? Who screams?

[@ecdhe]

For existing Raspberry Pi users, please note that you will need to upgrade more than just the board. First of all, you will need a different case as the ports are slightly different. Likewise, you will need a new power cable (USB-C) and HDMI cable(s) (micro-HDMI)

[@cheaterman49]

Upvote! Might seem obvious, but still useful - I for one didn't consider the case.

[@domby8897]

I can confirm that the Pi 4 does support 4k H265 perfectly, LibraELEC have an image out with Pi4 support. Theres also talk of HDR support on the way. I don't think the versions of Kodi and VLC on Raspian Buster are properly optimised.

[@GaryExplains]

You tested it?

[@domby8897]

Gary Explains Yes, tested it last night and it played perfectly.

[@GaryExplains]

@@domby8897 That is good news. I have read in other places that it still struggles with some H.265 4K files. Let's hope it comes to Raspbian soon.

[@RonLaws]

@@GaryExplains I imagine it's to do with VLC not using the NEON instruction set correctly, even on earlier iterations the pi would struggle to play even 1080p video in 'software mode' but players like omxplayer would run them perfectly fine as they offloaded the video stream to the hardware decoding on the chip.

[@GaryExplains]

@@RonLaws No, not NEON. The SoC has a dedicated video processor for decoding video.

[@KingsPhotographySolutions]

Yay Gary made a Pi4 review. 😁 You just know this is actually going to contain all the useful information we want. 😍 Clicks notification, (spots it's 17min long), (massive smile 😁). Thanks Gary, your the best. 😁 Have a great day, peace. ✌️

[@SuperEvanbaxter]

Yes, yes, yes! SBCs are starting to become really interesting for industrial applications, but 2GB is really a bare minimum, glad the Pi Foundation realized it!

[@cheaterman49]

You didn't get it, 1GB is plenty for hobbyists and most non-commercial headless applications.

[@jeffschroeder4805]

Recent software upgrades have dramatically reduced the overheating problem. Most heavy users will still want to add active cooling or install it in one of the newer heatsink cases. Additional processing power inevitably produces more heat.

[@marius3959]

Informative video. Please do cooling solutions in the future. Would love to see how many degrees it goes down. Thanks!

[@Ben-ry1py]

This is fantastic! Thank You Gary!! The Pi 4 is supposed to decode 4k video in h264 and h265. It's probably a software issue since this is so new.

[@GaryExplains]

@@TecboyJones I tried with both H 264 and H 265. Neither work with the preinstalled version of VLC... so you know, I did check.

[@GaryExplains]

@Z3U5 According to the Raspberry Pi website those are NOT supported for 4K.

[@Oberroxxor]

@@GaryExplains It supports 4k. See here: libreelec.tv/2019/06/libreelec-9-2-alpha1-rpi4b/

[@Oberroxxor]

You can see a test in the video and the developers already work on the RPi4 for 6 months. I guess they know this device. Higher bitrate still doesnt work quite good and the software has a lot of rough edges. I'm waiting to see the results which bitrates the RPi can handle in the end.

[@GaryExplains]

@@Oberroxxor So 1) it is only h.265 in 4K and 2) it doesn't work today on Raspian. I am reporting what I tested, not what is being claimed.

[@mr_beezlebub3985]

I’ll get a couple 4gb versions. One for an emulation machine, and the other just to see how well ARM for desktop use is.

[@rolyantrauts2304]

Don't as its not there are Arm boards available that scrape in the minimum of entry level desktop Pi4 doesn't manage irrespective of what they say. 4k two monitors is a joke when it can not play 1080p in a web browser, which it can not.

[@thanglongliving]

[@nullzero821]

one thing not mentioned here if you're upgrading is that you may need a new case as the board layout / ports have changed

[@francis2k488]

I now have a better understanding of Raspberry Pi. Good teaching is important. Thanks for this explanation

[@triestelondon]

Don't confuse "doesn't do 4k video decoding" (14:26) with this OS not supporting hardware 4K decoding on a Raspberry Pi 4. The pi does do haitch 264 and haitch 265 hardware decoding.

[@GaryExplains]

According to the Raspberry Pi website the hardware does NOT support H.264 at 4K. Also don't confuse "doesn't do" with it "could do if...." At the moment it doesn't do it. Simple.

[@David_Quinn_Photography]

I know these are low power, low profile products, why do we not have mSATA on these boards yet? I dont know much about that from factor but it would be interesting to see these get msata at least for faster load times.

[@jaygames1980]

What's a good heatsink for pi 4?

[@nickdsnik]

I had mine connected to a 4k TV and had problems displaying 4k content in VLC and from youtube in the chrome browser. However I installed Kodi and this was so much better with the 4k content. I believe that there is a known problem with the chrome browser and video at the moment but they are working on it. The Costa Rica 4k video ran on Kodi with the KZbin plug-in with a small amount of tearing and buffering. This may have been my wireless or my internet connection.

[@feedmyintellect]

How about the audio? Previous Raspberry Pis did not have a very decent audio output via the audio jack. People who built audio streaming boxes had to add alternative sound cards. Did the RPi foundation upgrade the audio chip on the RPi 4?

[@rosslomath]

Yeah we are getting a lot of unboxing but not much using of it would be good to see people actually using it and playing back a few vids or something.

[@4.0.4]

Almost certainly not. If you ask one of their engineers about the DAC they'd probably wait for a minute to think what that was and say "oh yeah it does that too, sure!"

[@ninline2000]

If you just want one for tinkering and projects you're better off with the Zero or A+. Much less power usage which is great for battery and solar powered and they are smaller and you're most likely running headless anyway. I know the zero is fine for camera surveillance boards. Now for a router, the 4 would be the thing.

[@richierich8085]

The RPi 4 can be used to supplement the PC for general purpose usages. Nice reviews by the way.

[@swanee]

Should try the alpha libreelec build, pretty sure they have h265 4k video working.

[@GaryExplains]

That is the whole point isn't it, I shouldn't have to "try" anything and especially not alpha software. At the moment using the preinstalled version of VLC it doesn't work.

[@Hybrid330i]

@@GaryExplains But thats the point you said, 'it doesnt do 4k video decoding' which isnt entirely true, Shawn is telling you it does, but you have to use something that supports it. I get your point though and im sure in time when everyone has got hold of these the support will be there.

[@GaryExplains]

@@Hybrid330i My point is that using the default software it doesn't work. Is my task to test the device and tell people what works and what doesn't work, or to make excuses?

[@Hybrid330i]

@@GaryExplains Thanks for your videos, I do enjoy and appreciate them, I guess from a viewers point of view, when you said 'it doesnt do 4k video decoding' I had a heart sink moment as for me (and many others im sure) 4k hardware video decoding is a massive thing. When I read down a bit and saw Shawn said it did, it was a relief.

[@GaryExplains]

@@Hybrid330i I wouldn't get too happy yet. It ONLY supports it for H.265 and it is yet unknown at what bitrates. This means that for other codecs like VP9 or WebM or H.264, it won't work. So it very much depends on the source of your video and the bitrate. Saying it "supports" 4K needs lots of caveats.

Since my desktop is an old AMD Phenom II X4 955 I don't think it would be much of a step down. Mainly all i need to know is if the 4 has enough horsepower to render videos on youtube and that sort of thing. All good wishes! Of course I'm subscribed, and gave you thumbs-up.

[@obsoletepowercorrupts]

1:00 You don't need ventilation? As your heat reference at 15:30 indicates it gets hot. Reviews already with it under a heat camera beg to differ (as in using it under load such as those dual 4k video outputs). It (Pi4) should have come with a heatsink as standard, not a mere option. It is (quote) _"uncomfortably hot"_ when doing any decent work (not even thrashing it - just video like not even a movie duration). Ironic how there is a heatwave when it launches. It is a prebuilt system board with an operating system called "noobs" (or raspbian) indicating it is for people who are learning (noobs), not just experts. The official keyboard mouse case bundle has a case that traps in heat. Personally I think if they were going for a larger board anyway, they could have made it a lot larger and thereby made a case that is bigger with better space to keep it cool. I'd have opted for a 8core or dual quad running lower and underclocked, not largely about making 4k dual video out as a priority. A larger board with it doing 8way parallel processing could have helped students learning about blake2sp and basic polynomials (which some GCSE maths students read about in revision guides between GCSE math and AS or ALevel maths, even if they only wish to do quadratic equations at GCSE). A bigger case and board being twice an old Pi3, like two side by side, like other brands can mean a square fan could have gone on it if desired. The a53 has been described as server class (and a bunch get used). The a72 is described as mobile device class. Dual quad a53 (like a humble parallel server) or octa-core would have made server sense, let alone a computer module breakout edge connector like say the turing board but with over 8 slots, not just 7. Turing (the father of computing) was largely famous when about encryption and blake2sp would have been a good learning situation with 8way parallel. It need not be the fastest board for that. It is about learning. Even if they did not go that route (a53 or octacore), the heat it has and its lack of ventilation in a case they want to get extra revenue from is a poor show when they could have prioritised cooling to be "enough" (i.e. don't make the board hot, and spread it over a different CPU setup and put in a better heatsink). A counterargument some might try to make be that they are selling it at a loss. However some people would rather have a board by a different brand that does the right things and costs more (which they may or may not end up using headless). A dose of plague might be 50p but it does not make the purchase good value. People use clusters of boards too so the board shape and its heat problems on the pi4 might get in the way of that with its a72 dominating the cooling space in a case with its hot a72 spreading heat over the PCB when people have to put in a heatsink. The Pi's website shops (of recommended sellers) has a tiny _"optional heatsink"_ and it will confuse people who will then look fo a bigger one. A good heatsink should have been a standard and supplied (or just us a different chip and do not allude to dual 4k hdmi, Pi). Those hdmi ports will snap like Kofi Annan famously breaking and winding a _OneLaptopPerChild XO_ computer charge handle. And the _"case and keyboard mouse"_ bundle does not give breakout _"mini to female hdmi"_ to convert and keep them safe but foolishly has two hdmi that suggest plugging straight into a monitor. People (kids and gutted parents alike) will plug that Pi4 straight into two HDMI screens to run 4k and then see the thing overheat and fail to understand why bad consequences occur. When little Timmy and Tammy plug in their Pi, tech nerds saying _"you get what you pay for"_ will anger the parents or the silver-surfer. It's not even as if the board currently having more support is an argument as with the Pi3 (which is supported). Debian and BSD and RISCOS (for video issues) and Ubuntu are not "properly" out for Pi4 yet. Or amibian and the media centre stuff.

That's not possible in terms of general use. For specialised tasks like certain simulations that can be run in parallel, combining multiple RP4s is an option, though. General compute tasks (like running desktop applications) cannot share resources like RAM or CPU-cores across multiple machines and thus wouldn't benefit at all from such combination.

Too many variables. It depends on the case, the cooling solutions used. In the high end, you could water/liquid cool the chips, and still keep it portable. On low end, a good heatsink and fan might bring down temps. Too many possible combos and scenarios

[@GaryExplains]

Cooling helps but also there are some firmware updates that also help. I might do a video about the latter if I find time.

I didn't finish this review because a couple of things said at the beginning of the review were (I feel) a bit misleading. You can't say EVERYTHING will be three times faster because that is a huge generalization and doesn't take other things into account. Also, the main reason it can transfer at over 100MBps is because of the USB 3, USB 2 is not capable of that speed, but it wasn't mentioned until after the speed is talked about.

[@GaryExplains]

To answer your points. I have a complete set of benchmarks pinned at the top of the comments. It is indeed a generalization that everything is 3 times faster, because some things are 4 times faster. As for the 100Mbps, you seem to be forgetting thst the Pi 3+ had USB 3 and Gigabit Ethernet, but they couldn't realize their max potential due to the bus designs.

How do these compare to a Mini Zotac

[@desultorilypanacea]

Would heatsink plus fan make big difference? Overclock?

[@4g0tt3nSou1]

I would say while it isn't required, I recommend a fan and heatsink. As for OC, this isn't something you want to over clock... This is a project board used for server applications and custom programs. If you are in need of higher clock speeds, the Pi's are not for you.

inb4 we get gigabit ethernet over usb c

[@flintstone1409]

Well the 4k video playback issue probably comes from the codec. The specification is just mentioning h265, according to your .webm file you probably tested vp9.

[@GaryExplains]

I tested h.265 and h.264.

[@AkhilPOommen]

Just a small correction. 64bit linux kernel can support 32bit userspace applications. So a golang binary compiled for 32bit rpi should run fine on a rpi 4 running 64bit kernel. But the reverse is not true though. If possible, could you share the geekbench scores?

[@GaryExplains]

Why is that a correction?

[@MegaScott]

RPI4b+ should have a connector to directly access the PCI bus. I can see an MMC add on, Video card upgrade...Etc

While I certianly enjoy anything with "coolness factor", it is just a simple question of time and money. In this case, I did a cluster already and there won't be much difference with a Pi 4 cluster. I need to spend my time on other videos.

i assume the gigabit ethernet shares with the 5GBPS from USB3? (as do maybe does other stuff on there that's internally wired to the usb3 bus where they were on the usb2 bus before?) you'll probably mention it somewhere in these 17 minutes also, i'm kind of in the market for a SBC that can sync laptop monitor connection like them 30-pins without bulky converters, i got some laptop screens, and 30-pin connector is pretty standardized, right? i could imagine there is standardized hardware you could program without being specific to 1 panel? 3 times faster you say? i like having rudamentary setups to code some stuff on and play some emulators when i'm visiting friends that have a spare monitor, this will be a very welcome friend.

[@sundhaug92]

The RPi4 is listed as doing h.265 decode at 4k60, could be a software-issue (drivers?)

[@GaryExplains]

If the hardware is as capable as claimed, then yes it is a software issue. But only supporting H.265 and not H.264, VP9 or WebM means that 4K support is limited at best.

It depends on your exact usage, but my guess is that It will still struggle with some of those, specifically KZbin and older games (if they are for Windows).

[@Muscleduck]

The thermal throttling could be the reason why you didn't get 4k decoding to work? I'm fairly sure I've read that 4k decoding should be possible.

[@GaryExplains]

No, it isn't the thottling. 4K is meant to be supported in the hardware for H.265, but not H.264. At the moment it doens't work.

[@Muscleduck]

@@GaryExplains after posting my comment I read some more comments and gathered as much. The Rpi foundation is probably at work trying to fix the issue. Maybe it's a driver/codec issue.

[@GaryExplains]

I am sure the folks there are working on it. My point is that it doesn't work today and I am not a PR representative of the foundation to make excuses about why it doesn't and what might happen in future releases.

@@GaryExplains oh but I agree. It's very unfortunate that this feature isn't supported yet. Some reviewers (like from the media player communities) were probably really looking forward to this.
