Nvidia responds to AMD’s answer to G-Sync tech

Friday, 10th January 2014 13:25 GMT By Dave Cook

Nvidia’s Tom Petersen has responded to AMD’s answer to his firm’s G-Sync tech, and went so far as to call the competition’s CES 2014 ‘free sync’ demo into question.

We reported that Nvidia’s G-Sync monitors are coming Q2 2014. Hit the link for a full report.

The monitors boast embedded G-Sync chip sets designed to enhance gaming visuals and reduce infidelities such as screen-tearing and lag.

Speaking with TechReport, Petersen underlined AMD’s similar concept as validation of the G-Sync concept, but questioned the company’s use of laptops to showcase its tech at CES.

Petersen stressed that laptops feature a more direct connection between the unit’s GPU and screen, and have a different display architectures to desktops. Therefore, there is greater need for something like G-Sync on desktops to maintain variable refresh and other potential display issues.

This discrepancy between desktops and laptops is why Nvidia came up with the G-Sync unit, says Petersen, which replaces a rig’s scaler ASIC with Nvidia’s bespoke logic. To Peteren’s knowledge no such equivalent exists out there in the market. “We would know,” he said.

The report is very technical, but give it a look if you want to dig deep into the tech behind G-Sync and Peteren’s concerns around AMD’s use of laptops.

What do you make of the above?

    Yeah cry me a river Nvidia. Unlike their proprietary G-Sync, AMD can offer their solution to all monitors that support variable refresh rates.

    Now, what do you think monitor manufacturers will do? Add a proprietary hardware and fatten Nvidias wallet, or add a new monitor feature and pay nothing to anyone? You know the answer.

    Thanks Nvidia, G-Sync was fun while it lasted. Although AMD needs to step-up and show better demos. Nvidias G-Sync presentation created waves since the reveal was done right. AMD can easily kill G-Sync IF it works fast. And all AMD cards and APUs already support this feature. Why should anyone pay for proprietary hardware thing if AMD can offer it free of charge?

    is it me or does Nvidia seem to be sour lately or they boast about themselves

    @1 because it’s AMD proprietary hardware as well?

    Also, he does have a point. Showing the demo on laptops is different than showing them on monitors as the signal is not sent through the same channels.

    I would like to see AMD tech on a monitor before I pass any judgement on it but, at this moment, I think AMD are in the ‘Yeah we got it to’ camp.

    @4,
    You don’t need to buy separate hardware for monitors in AMDs solution.
    Although I agree that AMD needs to show more, as I said earlier. But VBLANK support will only increase after this.
    Is it better to buy a VBLANK supported monitor or G-Sync monitors which will have a cut for Nvidia added in them?

    We will see when both technologies get released which is better.

    If AMD’s option is only on laptops its not worth my time personally so Nvidia’s option would be better even if it did cost money.

    amds option is already part of a vesa standard, so not really proprietary

    amd and nvidia probably could have forced it into the last as well if they wanted to, but:
    - amd mostly has industrial embedded devices and desktop/notebook where the idea of vblank made little sense from the business standpoint
    - nvidia on the other hand is established in the mobile phone/tablet market and you take every watt you can get there

    should not be that hard to make it part of the actual displayport standard so display manufactures have little trouble implementing it

    As I understand it, G-Sync allows for the hardware to respond more or less immediately to software frame renders. I.e., it can vary the sync rate on the fly based on the speed of the software updates to the frame buffer. Can AMD do the same with existing monitor hardware? I find that hard to believe. I can believe that it could optimize the hardware sync rate to the average software fps, but not moment-by-moment changes. Am I wrong?

    AMD didn’t show decent demo compared to Nvidia that proved that technology exists.

    That’s always with AMD technologies. They tell and don’t show. Then they release Broken TressFX and that’s it.
    Where is TressFX now? In the seven depths of hell after Tomb Raider.

    but AMD still have time because I’m not really a fan of announced partners with monitors for next year. Where is my favs like DELL or SAMSUNG.

    The thing nvidea should be worrying about is mantle because if that works.
    No one will buy nvidea cards anymore.

    If a big enough demographic goes for it Nvidia will add to mantle it is afterall open source.

    @12 Mantle is AMD tech not open source it only works with amd graphics core next cards.

    ^Nope. Your info is old.

    Nvidia won’t spit on mantle the only reason this will even partially survive is because of the consoles and probably afew devs linked to AMDs games program
    Pointless api.

    What wasn’t mentioned was that when DP1.3 comes out, it’s already Freesync compatible, so it”ll be a case of free Freesync for all.. G-sync is DOA already.

    You say that like it’s just a software update. It’s not. If, and when, the new Displayport 1.3 (EDP) standard is to be implemented is unknown. i.e. there is no timeframe.

    So, while G-sync is typical Nvidia lock in bullshit they’re still beating ‘Freesync’ to market.

    Either way you will still need a new monitor.

    @17

    Maybe so.. but you won’t be paying extra for it.. plus it’s a standard feature of DP1.3.. it’s not a feature people will have to look for… but most of all..It’s not proprietary. If you buy DP1.3 Freesync you can use ANY gpu, if you buy G-sync you are stuck with Nvidia for as long as you wish to use your monitor….G-sync holds NO advantage over Freesync.

    I’ll never buy a monitor with G-sync, I want to be able to change the brand of my gpu should I want or need to.

    Yes, G-sync will be the betamax of this tech…

    Nvidia fail, no, AMD fail, no PS fail, no, Xbox fail, no Nintendo fail, no PC fail….

    I like pie.
