Cpu 4k streaming

[apaar123]

Which cpu is available to stream 4k games at 60fps using obs/shadow play? Will ryzen 7 1800x be able to do it?

Yes, if you can afford the 1800x great, if you're short budget you can just get a 1700 and OC it... either will do great, alternatively you could wait Intel's x299 chipset and Skylake-X coming at the end of the month.

Do you think they will be higher cores?

1700 would be best as it OCs pretty much as well as an 1800x.

given that there isnt a service in existence that can actually livestream a game capture at 4k, what's the point ?

My Ryzen 5 1600 can stream 4k just fine, Of course I am also using a Capture card to and Xbox One S so most of the heavy work is already off my hands. I would have to say the i7's and the Ryzen 5 and 7's will all stream 4k.

edit: at least not over the internet anyway, yes i'm aware that you can do LAN streaming at 4K but is anyone actually doing that ?

Yes the i7 7950x will be 12c/24t

i7 7900k 10c/20t

i7 7850k 8c/16t

i7 7800k 8c/16t

 

Since the new mainstream i7's will finally feature 6c/12t

I just read about them. I will wait and see the pricing

Get a 1700, no need for an 1800X or an Ryzen X model (1500X excused) invest the $/£180-200 saving elsewhere in the build, E.G GPU

My prediction is maybe 15-20% better performance at 2-4x the price with expensive motherboards.

Some people are assuming price will be as of extreme cpu

Their pricing will follow X99 (extortionate) + a little extra for skylake IPC and don't forget a $200-300 starting price for motherboards

So I assume they will cross 1000$

No doubt yes

I think Youtube accepts 4k streams.

 

Anyway, Shadowplay does the encoding in the video card, so basically ANY decent processor (let's say a quad core) should be able to play a game in 4K and capture it in 4K using Shadowplay.

With the modern cards in the Polaris series, you can do it with AMD's Relive as well..

For both, the driver overhead (and transferring compressed data from video card to computer memory) will use probably 5-10% of the CPU.

The capture application (OBS for example) only has to format the compressed data into a stream (very little CPU) and push it to a remote server ... so it's just a question of your computer being able to handle uploads in the range of 20 mbps to 50 mbps while you play the game.

 

With a Ryzen 1700x-1800x it should even be possible to do live streaming at 4K 30fps or potentially even 60fps using software encoding, using x264 .. you probably will have to go in settings and set it to ultrafast and then go even futher and disable CABAC maybe (use the lower cpu usage less efficient CAVLC method of compressing bits) and just let it use a ton of bitrate like 30-50 mbps and you should be able to stream 4k just fine.

 

It could depend on the game as well, for example something that's low amount of motion on screen like let's say Heroes of might and magic which is turn based or point and click adventure games like Syberia 3 , would be streamable just fine in 4K hardware encoded or software encoded using x264 because there's not much motion in them so they can use previous frames to reduce the amount of data needed to compress in current frames.

1700 is actually a downclocked 1800X right?

[mariushm]

It's a processor that for whatever reasons, AMD decided to make it in a 65w TDP package and make it slightly less overclock friendly.

 

Whatever reasons could be  one or several cores would use too much power and make too much heat when clocked at 1800/1800x speeds (so they couldn't sell it as a 95w tdp cpu), or one or several cores may not overclock to 4.0-4.1ghz so they could not sell it as 1800x because the cpu wouldn't overclock and look bad , or maybe cache memory fails at too high frequency, or maybe it's simply a good enough die to be sold in only 65w tdp budget

 

edit: changed 4.8-5ghz to 4.0 .. 4.1 ghz, i was thinking of 7700k when i wrote the message

in what terms only 4.0 ghz overclocking effecting the performance of 1800x?
