More PR from AMD...who would have thought ^^

Come Q2 this year, I will go from CRT's to LCD's...my money is on Gsync being the tech that is available..and superior.
So 3 x $$$ from me to the tech that isn't just PR ;)

I hope that G-sync will lessen the strain ;)
I am running low on backup CRT's....only have 2 backups left...time is running out...and nanoCRT's are no where in sight...so I'm am kinda at a crossroad.

I hope that 3 x monitors in WoT/ARMA3 will make up for it *crosses fingers*

I see your point about lessening the strain:thumbsup:,jeez lets hope good quality screens gsync enabled are soonish:).

This is the controller board.

See how the LVDS pinouts have no port? They're not used. Above it is the eDP port, labeled DP OUT.



It's okay. Had to open it up to tape over some spots where backlight was bleeding out in the chassis. It's pretty ghetto, I'll upgrade next year (or this year, on black friday). It doesn't overclock, as I understand it it's limited by the eDP connection. The ones that overclock use dual-LVDS and a different board.

DP. Display Port. There is nothing labeled eDP. At least none that I can make out. The pic is quite blurry.

I don't think resolution really matters for this type of technology. 8K 12K whatever, shouldn't make a diff.

I beg to differ. The higher the resolution, the more of a struggle it is to maintain 60+ fps. In other words, the more likely one's frame rates are to dip to the 45-60fps range where G-Sync is of most benefit

Edit: unless you meant something different?

In an interview with The Tech Report, Tom Petersen (Nvidia executive) stated,

"That said, Nvidia won't enable G-Sync for competing graphics chips because it has invested real time and effort in building a good solution and doesn't intend to "do the work for everyone." If the competition wants to have a similar feature in its products, Petersen said, "They have to do the work. They have to hire the guys to figure it out."

It appears that AMD has decided to give Nvidia a little jab back for that comment in a blog titled,

"Doing the work for everyone". ;)

"In our industry, one of the toughest decisions we continually face is how open we should be with our technology. On the one hand, developing cutting-edge graphics technology requires enormous investments. On the other hand, too much emphasis on keeping technologies proprietary can hinder broad adoption.

It’s a dilemma we face practically every day, which is why we decided some time ago that those decisions would be guided by a basic principle: our goal is to support moving the industry forward as a whole, and that we’re proud to take a leadership position to help achieve that goal.

The latest example of that philosophy is our work with dynamic refresh rates, currently codenamed "Project FreeSync”. Screen tearing is a persistent nuisance for gamers, and vertical synchronization (v-sync) is an imperfect fix. There are a few ways the problem can be solved, but there are very specific reasons why we’re pursuing the route of using industry standards.

The most obvious reason is ease of implementation, both for us from a corporate perspective and also for gamers who face the cost of upgrading their hardware. But the more important reason is that it’s consistent with our philosophy of making sure that the gaming industry keeps marching forward at a steady pace that benefits everyone.

It sometimes takes longer to do things that way — lots of stakeholders need to coordinate their efforts — but we know it’s ultimately the best way forward. This strategy enables technologies to proliferate faster and cost less, and that’s good for everyone.

The same philosophy explains why we’re revealing technology that’s still in the development stage. Now’s our chance to get feedback from industry, media and users, to make sure we develop the right features for the market. That’s what it takes to develop a technology that actually delivers on consumers’ expectations.

And Project FreeSync isn’t the only example of this philosophy and its payoffs. We worked across the industry to first bring GDDR5 memory to graphics cards— an innovation with industry-wide benefits. And when game developers came to us demanding a low-level API, we listened to them and developed Mantle. It’s an innovation that we hope will speed the evolution of industry-standard APIs in the future.

We’re passionate about gaming, and we know that the biggest advancements come when all industry players collaborate. There’s no room for proprietary technologies when you have a mission to accomplish. That’s why we do the work we do, and if we can help move the industry forward we’re proud to do it for everyone."

So AMD's idea of doing work...is to do PR...and hope others pick up the ball :whiste:

Seems like the same PR department that sent Intel a "Valentine" card a few years back showing a bulldozer running over a Sand Bridge. That didn't turn out so well though...

Aha. Mantle is moving the "industry" forward, but G-Sync is not?

Hypocrite.

What you are referring to is the strength of the graphics card aren't you? Because that logic applies right now with say for example the weakest of Kepler cards trying to maintain frame rates above 30 at 1080p. Unless I'm missing your point?

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 ^^

AMD is making a lot of PR these days...to bad they don't seem to follow up with actual products...like "Mantle" that has gone from December...to January...to Q1 now.

I remember AMD talking about OpenCL physics on GPU's too...hasn't come true.

Or like AMD's HD3D...same thing...they needed other to pick up he slack.

The pattern is obvious, so your "no"...seems out of touch with reality...just like AMD's PR ^^

The display controller they would need contains a framebuffer plus PSR.

According to those articles, Freesync uses prediction rather than a frame buffer, hence there is no need. What does PSR stand for?...

And still not delivering the gsync experience. And its certainly not "free". AMD should have called it was it was, R-sync/A-sync or whatever instead of the misleading name.

To make an equally credible statement, Freesync works 100x better than Gsync. Wait, but I haven't tried it you say? Well, that's the problem with making statements like that...

Gsync with ASIC would drive the price down to peanuts and a better solution since we obviously wont get an industrial standard that actually fixes it. Both freesync and gsync are nothing but hotfixes to the actual problem. gsync is just a much better way of doing it.

But why can't we get a standard? Like I mean, why not have a technology that Nvidia and AMD can both use, and monitor makers can implement based on a standard, rather than proprietary tech. I don't think Freesync is going to happen, especially not soon (they obviously just pulled the demo together in a short time) but if I had to choose, I'd rather have Freesync.

I'm not sure how those are equal when G-sync actually exists.

They're 100% equal, he's making a comparison between products which don't exist (and he hasn't tried). It's like saying Maxwell will get 500% more FPS than Hawaii, it's a useless statement since Maxwell isn't even out.

So i guess you don't know that PSR is using a) a frame buffer to store an older image and b) the GPU needs to know what happens next to send the command in the VBLANK time...

PSR is absolutely useless to recreate something like G-Sync.

But why can't we get a standard? Like I mean, why not have a technology that Nvidia and AMD can both use, and monitor makers can implement based on a standard, rather than proprietary tech. I don't think Freesync is going to happen, especially not soon (they obviously just pulled the demo together in a short time) but if I had to choose, I'd rather have Freesync.
You're right. But then why do we need Mantle and TrueAudio?

And because someone mentioned Panel Self Refresh and eDP:
The GPU is still responsible to trigger the PSR method. Which means it's only working with Triple Buffering and so with V-Sync. PSR is not able to trigger the SDP command itself.

/edit: Reading more about eDP and Panel Self Refresh i think nVidia is modifying the DisplayPort stream with the G-Sync. It's not the GPU which put the command in the VBLANK break but the G-Sync module. That's the reason why they dont need additional buffers.

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!)

That's the reason why they dont need additional buffers.

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!)
