General rule of thumb with technology is that when you try and pair newer technologies with older technologies, the newer technology simply yields to the specifications of the older tech, backwards compatibility; not forward compatibility.

Essentially the older card isn't going to know how to use the new FreeSync timings, and won't know when to produce a signal or not produce a signal. If it has data ready to go, and tries to put it out at a different time than the newer card, you will have problems.

This isn't just about making a display have variable refresh rate, but also getting the GPUs to sync with that and effectively communicate with that feature to make it work. They have to work in step with one another, and if an older card doesn't know how to do that, it isn't going to work.
The displays that are in use that can use it are laptop panels that use eDP, there are no desktop displays that use eDP!

So, yes, new hardware will be required for this to function in the desktop environment. Simply updating firmware isn't going to change the actual connection type being used!

There is no assumption.

The older card isnt displaying anything. I made a specification situation where it will work.

We have years of proof that same cores work no matter the display ports. poke.gif

Laptops, not desktops. And they, as in AMD, confirmed that it's not in desktops.

But it can't do VRR. There's no VRR protocol for DP 1.3 as of yet to my knowledge. DP 1.2a is for VRR at 4k and 60 fps, and you'd likely need bleeding edge hardware to do achieve that (assuming that an eDP or DP 1.2a 4k monitor even exists).

Nvidia isn't going to gain any sort of market penetration anywhere with G-Sync's pricing. How well Freesync does is mostly on AMD's shoulders to push for it with manufacturers.
Gsync pricing isn't steep at all, and compared to the benefit of taking the workload off your GPU, it would likely end up being the cheaper alternative for most enthusiasts (gains from Gsync vs. added Freesync GPU needs, cost in dollars for same results).

Unless Freesync is ridiculously easy and cheap to implement, it'll probably be a "supported feature" in a few gaming monitors, and standard screens won't get it for at least a few years.
Freesync is ridiculously cheap to implement. The VRR protocol has been around for years. This is just the first time is is being added as an optional protocol for DP 1.2a standards. The VRR protocol went unannounced when it was first created, NVidia explored it, and went with Gsync instead.

Edit: Apparently DP 1.3 will support VRR. I'd still be willing to bet Gsync is the cheaper solution. NVidia didn't just choose it to sell proprietary hardware. There is a reason for offloading the work.

I disagree, G-Sync is expensive regardless of the benefits, you will need a new monitor $499+ or a compatible monitor (existing) and $200 G-Sync kit. I would rather put $200-500 towards other components more beneficial in my opinion.

Or manufacturers will just slap a 'gamer' tag on and charge you $700 for a monitor that supports a variable refresh rate to support Freesync.

The really clever part by AMD isn't the implementation, it was using the word 'free' in the nomenclature.

You're going to pay for this feature with either GPU vendor.
Meh

I really can see why people well versed about this matter don't touch the news section with a 10 feet pole.

This is largely due to the premium that goes with anything that early adopters want to buy, and is not inherent to the technology.

As long as the technology remain proprietary there will always been a premium

Nice one AMD, so glad they support all the right software
