[TechPowerUp article] FreeSync explained in more detail

[sontin]

They don't need to modify the "stream", because DP is a packet based connection and allows to send custom packets/commands. (hint, hint, HINT!)

Yes, but unfortunately to setup the display you need to know the future. And for that it's necessary to use additional buffers. But if you able to modify the stream after the GPU sent it then you dont need buffers but only a direct communication to the gpu...

When the VBLANK runs out, they need to display something. They could 1. ask the GPU for the last frame or 2. cache the last frame somewhere (hint, hint, HINT!)

And we know this is only the case when it takes longer than 33,3ms to render the next frame.

Should we just start one permanent vaporware thread?

 

[sushiwarrior]

Do you know how absolutely and completely wrong you are?

Do you think all the previews and reviews of G-sync were just made up of nothing?

Gsync exists, Freesync doesn't, ergo making any conclusions about how one will compare to the other ("Gsync will be better") is a logical fallacy.

I do believe this is far more inflammatory than anything I wrote, and seriously, the last page has been nothing about Freesync. The last couple pages have been nothing but "it doesn't exists, it's PR" and rebuttals.

He wasnt accuseing you of it, he was agreeing with you.

He pointed out it seems like people move from thread to thread, and derail or try to get them locked.

I agree with that sentiment too and I dont believe the mods even care.

It's an effective tactic, unfortunately.

I wasn't talking about your post sorry. I was talking about all the PR nonsense we've been reading for DAYS now.

Gotcha... back on topic.

So who is AMD working with to make eDP monitors for the desktop space?
You know like NVIDIA is doing this:

http://www.geforce.com/hardware/technology/g-sync/where-to-buy

You can get it already..and more are comming...unlike AMD's empty talk ^^

That is not moving the industry forward. That is paying a single monitor manufacturer to produce a single model incorporating G-Sync. Whereas AMD is working with industry as a whole to hopefully bring FreeSync to everybody via DP 1.3, Nvidia included.

Even if it's proprietary, if Gsync drums up enough interest from consumers every panel make will take note and want a piece of the pie.

That was the purpose of AMD's showing Freesync at CES even at such a rudimentary stage. They wanted increase interest in consumers and show display makers there is a market for it.

So your claim is that there will come 1(one) single monitor supporting Gsync (because NVIDIA paid for it?) and that is it?

Did I understand you correctly?

Very true. I do give credit to Nvidia for bringing this problem to the forefront and for designing a solution for it. However, they have chosen to lock this solution to their own hardware.

AMD's answer to screen tearing may or may not end up being quite as effective as Nvidia's, but will have the benefit of working for everybody (Nvidia included). And it will not require any extra hardware to be added to a monitor beyond compliance with DP 1.3 variable refresh rate, unlike G-sync which requires an additional ASIC.

So while G-sync may be first out of the gate, ultimately it would be better for us end users for FreeSync to win out.

As far as I know, there is only one model of monitor from one manufacturer that is currently available with a G-sync module. And that is the Asus VG248QE. Unless there are others out there that I haven't heard about yet.

 

[96Firebird]

Then I guess FreeSync isn't moving the industry forward either, because that is in 0 desktop monitors that I can buy.

Is that what you are saying?

There are actually more than 4 coming to the market, by more than 2 companies. This is one:
http://www.pcper.com/news/General-Tech/CES-2014-ASUS-ROG-SWIFT-PG278Q-120-Hz-G-Sync
http://www.pcper.com/news/General-T...and-27-Inch-Monitors-NVIDIA-G-Sync-Technology
http://www.techspot.com/news/55233-...r-equipped-with-nvidia-g-sync-technology.html

There is also the Asus VG248QE we all know about.

That wasn't what I asked.
Shall I repeat the question?

Oh noes...NVIDIA must soon go bankrupt paying everyone to do everything

I'm pretty sure you know exactly what I'm saying, but I'll spell it out for you anyhow.

Of the two options, one that works on Nvidia only and one that will work for everybody, I believe the one that will work for everybody to be the best overall solution for us, the end consumers.

 

[sontin]

What is the other method which equals G-Sync?
I hope you dont mean FreeSync, because this is the exact opposite of G-Sync...

Unfortunately, AMD's Freesync won't work on Nvidia, at least not until Nvidia changes their cards to support certain features.

Hopefully that changes.

Another thing to consider is that Freesync may not work as well. AMD is trying to utilize existing tech to make this happen, but they may end up compromising a bit in the process. They mentioned that they think they can mimic G-sync with the use of VBlank and triple buffering. If they need triple buffering, that may mean they are introducing latency into the mix. Maybe as a look ahead system.

That is nothing like what you said before, but thanks for clearing it up. :thumbsup:

I personally don't think the FreeSync solution will be as elegant or lag-free as the GSync solution, but we'll see.

You actually believe FreeSync will come to any sort of fruition?

The articles I've read so far say that FreeSync produces similar results to G-sync.

"Dynamic refresh rates would theoretically work like G-Sync by specifying how long the display remained blank on a frame-by-frame basis, providing for smoother total movement."
