Do the new Ryzen processors support 4k Blu Ray playback? (i.e. do they have the DRM instruction sets?)

Greetings,

In order for the new 4k Blu Ray drives to work, the CPU needs a special instruction set.  This instruction set has been available on 7th gen Intel CPUs.  However I am wondering if the new AMD processors (finally) have these instruction sets in order to play back these disks?

Re: Do the new Ryzen processors support 4k Blu Ray playback? (i.e. do they have the DRM instruction sets?)

I'm not sure about the CPU, but the GPU has HDCP 2.2 so regardless of the CPU the graphics card can play it and output it unless you mean vega integrated CPU's what are they called 3200G or something like that?

If you were worried about needing special CPU's to play back 4k content, you actually don't so much, lots of CPU's nowadays have HEVC acceleration or hardware decoding though, especially ones with integrated GPU. For example for years intel only made CPU's and didn't have graphics cards but their CPU's had a 4k decoding option you could enable in your mediaplayer software or something like that. Also it was a concern in the past to use the CPU as a copy protection thing, but that was while they were still working on getting enough "copy protection" to make 4k content a viable option for streaming on the desktop. It mostly concerned Netflix and other services streaming their HQ 4k HDR videos to peoples computers and not wanting them stolen. But since edge browsers been able to stream in 4k for a while now though most other browsers couldn't for the longest time dunno if they're still 720p stereo, theres actually a better solution, using the windows 10 store Netflix app gives you better quality and dolby atmos audio and such. If there exists some sort of new 4k Blu-ray disc ROM drive in your computer I doubt it needs a special CPU because the drives aren't built by the CPU manufacturers and then the drive would be useless as majority of the world have very very not high spec computers. The people who have brand new expensive CPU's are like less than the people who own 4k HDR TV's. You don't expect everyone in china and india to afford a high spec brand new computer every time they wanna put in a hard drive or disc drive do you? that's impractical. what good would having a specific CPU even do for the bluray drive lock it into anticompetitive monopoly?

Actually the movie industry has DRM on 4k Blu Rays which really do need a special CPU instruction set.  This is beyond HDCp 2.2.  When I got my 6800k (x99 system) I was pretty disappointed when it didnt have the special instructions even though technically being a 7th gen processor.

Pioneer Ultra HD Blu-ray burners pack 4K playback, but good luck meeting the PC requirements - Extre...

Re: Do the new Ryzen processors support 4k Blu Ray playback? (i.e. do they have the DRM instruction sets?)

I’m Just going to remind you that article about 4k blu-ray players needing special CPU instruction sets was from 2017, the same year that they said “early this year graphics cards and TV’s will all be hdmi 2.1! any minute now!” then you read an article saying “we’ve finally standardized and agreed on HDMI 2.1 so its now a standard that exists.. and then nobody manufactured any HDMI 2.1 hardware chips or shipped them out for several years. At that point in time 4k HDR Netflix streaming may have been impossible in all the browsers. If you search 4k bluray drives for PC use on sites like amazon, theres USB external ones, since USB can be plugged into many devices not just computers, I think there isn’t any requirement about CPU. Also the fact that all the 4k blu-ray drives for PC do not have a single CPU requirement listed in their product description or they wont work for their intended use indicates that at this point in time someones likely not telling the truth here. But yes its true that Microsoft and Hollywood were trying to implement such features into the CPU’s in the past to better “secure” their content and they may do so if they haven’t already but the thing is, it does not seem to be a requirement at all yet. Maybe in another 5 to 10 years time something like that could happen because 90% of the world would then maybe have a CPU with the special DRM but until that time who the hell would sell a product 90% of the world cant even use.. Currently they’re still trying to get people to buy 4k TV’s when they aren’t broadcasting in 4k and now they’ve got 8k tv’s on sale, when was the last time you saw an 8k movie?

I use Cyberlink which plays CD/DVD/BD/UHD fine.

My CPU, R5 2400G is recent so it has a modern support for what matters to run Windows efficiently

Do you have the Pioneer BDR-211UBK or LG WH16NS60? That's compatibility I'm curious about.

I use the LG drive mostly as they are readily available locally

Re: Do the new Ryzen processors support 4k Blu Ray playback? (i.e. do they have the DRM instruction sets?)

The instruction set (Intel SGX) is still not supported by AMD's current Ryzen 3rd generation CPUs.

I have an AMD Ryzen 9 3950x on a Gigabyte Aorus x570 with an Nvidia GTX 1070 and a Pioneer BDR-211UBK. I can only play up to the standard normal Blu rays, not the 4k UHD Blurays. This is using the accompanying software which is Cyberlink.

User eccentric is not up-to-date with the Intel SGX requirements of UHD drives. It doesn't matter if all your components are HDCP ready as long as your UHD drive is deprived of Intel SGX from not having the right CPU and motherboard it won't play 4k Bluray discs.

I don't believe user hardcoregames above is actually able to play 4k Blurays through his drive either. He may be confused by the difference in UHD and just BD discs or he may be playing the normal Bluray discs that come with the 4k discs (pretty much all the 4k Blurays come with a standard normal Bluray as well in the event the buyer cannot play the 4k disc). The page for the LG drive even mentions you are required to have Intel SGX support from a 7th gen Intel CPU or above, so it is not possible he's using an R5 2400G and bypassing the Intel SGX requirement (unless he's using a certain fox software to bypass DRM which is a hit-or-miss for most discs, especially newer releases).

Re: Do the new Ryzen processors support 4k Blu Ray playback? (i.e. do they have the DRM instruction sets?)

It was my understanding that the graphics card companies and Microsoft themselves developed special security measures to allow 4k 10bit HDR content (hollywoods movies and 4k media AKA Netflix, hulu, amazon) play back 4k 10bit HDR HEVC encoded content on PC with copy protection and content protection built in at the hardware level as well as HDCP. Basically the 4k bluray disc to play back you will need the correct software AND the correct drivers and the correct graphics card (pretty much anything that says hardware HEVC decoding same way TV's work once it detects the hardware decoder chip inside the TV Netflix or whatever app with the HEVC passes it to the Realtek or whatever brand of 4k video decoding media chipset is inside for security/decryption and playback) having all this extra additional nonsense by only intel is rubbish as if it only exists in intels CPU's and certain models of 4k drives then its not a standard and is just a brand exclusive feature. If its not on the HDMI forums Blu-ray website Blu-ray.com then its not required to play back Blu-ray discs.

Its true that two models of Blu-ray disc players for PC require you to have a certain model of an intel integrated graphics mother board and in intel CPU for them to work.. But since Blu-ray.com and HDMI forum do not seem to list it in bold on their website as a requirement or a method of playback it seems doubtful especially since from its time of development the intel platform was highly insecure and has been for the last 20 years or so because its all these different design flaws intel has over the last 20 years when they made the standards that left them vulnerable for the entire last 20 years but people only recently published a few articles about them because the attack methods became known and painfully when intel and Microsoft patched them in software it hurt 4k reads and write performance which is every current operating system as larger HDD's and files nowadays require a minimum of 4k sector size partitions. 

You can see proof here that spectre and meltdown and a bunch of other intel security breaches that are built into the hardware and not entirely patchable or correctable without buying a different brand of computer and since intel makes the x86 standards and microprocessor stuff a number of other CPU's were minimally impacted too like ARM and AMD. So yeah because intel gargle man bean bags your mobile phones security is at risk. Anyway heres some stuff on the Blu-ray.com forums claiming they've proven intels SGX is breachable and not safe to use for protected movie content, probably why theres hardly any drives that support it and only certain mainboards support it. 

GitHub - lsds/spectre-attack-sgx: Spectre attack against SGX enclave 

It was also vulnerable to plundervolt the entire time the SGX software was in development and released and was only recently patched.

https://www.darkreading.com/vulnerabilities---threats/intel-issues-fix-for-plundervolt-sgx-flaw/d/d-... 

However although intel issues fixes because its at a hardware or kernel OS level often times the fixes impact performance and speeds and to be honest they may only partly fix it but not really say that. Lots of spectre and meltdown cant be entirely plugged up theres fixes for it but they don't fix everything because its at the hardware level. 

So yeah the reason why nobody wants to touch their SGX rubbish is maybe because intel wants to sell it to them for high prices or it could just be because who wants to pay for insecure extra security features? I sure don't.

Over the last year or two theres been maybe 10 or more exploits and they just keep coming with intels CPU hardware and stupidly a massive number of businesses run intel hardware so yeah. You don't like AMD CPU's because they wont let you pirate 4k Blu-ray movies when a cheap 2nd hand xbox one S would let you play them back probably in better quality and would get frequent software updates and fixes and patches. Heck an xbox one X would be HDMI 2.1 which no current graphics card is. Sure playing back 4k media on PC with daum potplayer or MPC-HC software and processing the image makes things look better, or using your AMD adrenaline software to crank the saturation slightly and set to video classic cinema profile makes it feel better. But you could always still use your purchased 4k disc drive for what it was designed for, copying larger files to or from larger Blu-ray discs. Those drives aren't popular because to play back a 4k disc you just need a 4k disc player and the drives for PC are meant as storage media. Had you been a filmmaker or photographer you would get amazing use from your 4k drive. 

Check out how large the filesizes are on 4k content. 4kmedia.org has some great HEVC 10bit HDR files for download you can playback with daum potplayer and the windows 10 HEVC extensions codec from the windows 10 app store (may cost $1?). I like the travel with my pet or the red bull experience videos on 4kmedia.org

SGX was trashed by Meltdown and Spectre

I usually get new BD drives when the new model surfaces mostly as firmware updates are uncommon

I use dual drives mostly to handle feed music to iTunes by the pile
