Well the reason that Adaptive-Sync is cheaper than G-Sync is because it does not require any proprietary hardware.
While it is not "free" because it won't work with just any DisplayPort monitor, the costs should be a fraction of the G-Sync module, and some displays may only need a firmware update to support it.
Eventually I would expect to see it as a standard feature of any monitor with DP, because it will simply be a standard feature of newer display controllers.
But the main issue I have with NVIDIA is not that they did not contribute to the Adaptive-Sync spec or open up G-Sync - though it would have been better for everyone if they did - but that they refuse to support it even though it is now an official VESA spec - not an AMD one.
I believe it was PC Perspective who said that the G-Sync module is apparently costing manufacturers $100 from NVIDIA. That is an
absurd cost, and it means that G-Sync displays will never compete with Adaptive-Sync ones on price. They will always be $200+ more expensive than the equivalent display with Adaptive-Sync, because Adaptive-Sync is using standard display controllers.
And G-Sync modules are even more expensive to integrate with a display if you want them to have multiple inputs and the standard options that we expect to see on monitors these days. G-Sync bypasses all of that, while Adaptive-Sync requires pretty much no internal changes to the display, other than a newer revision of the hardware they were already using.
Not really though.
OK, Intel and AMD are using separate sockets which means that they are not interchangeable.
But they're using standard USB, PCIe, SATA, HDMI, DisplayPort connections etc. for peripheral devices.
They both use standard DDR RAM in a standardised configuration.
They both work with standard ATX power supplies.
They use standardised form-factors for the motherboards so that they fit in a regular case instead of an Intel or an AMD case.
You don't lose access to all your peripherals because you switched from Intel to AMD.
And because they use standardised PCIe connections, there are no problems using an NVIDIA GPU in an AMD system.
They're not doing anything proprietary to block that.
G-Sync is the equivalent of replacing all of those with NVIDIA-specific connections that raise the cost of each component by £100, and making it so that those only work with NVIDIA-certified motherboards.
They are trying to lock people into their "platform" which goes against the openness of the PC platform as a whole.
While you might be happy to, few people are going to spend £600 on a monitor and just swap it out at will.
For most people, spending £600 on a monitor means that they'll be using it for at least 5 years.
And if they can only use all the features of the monitor with an NVIDIA GPU, well they're far more likely to buy an NVIDIA one next, aren't they?
You're missing the point though. This is not AMD vs NVIDIA.
Adaptive-Sync is not "AMD's G-Sync" it's
everyone's G-Sync.
Anyone can support Adaptive-Sync, because it's a part of the DisplayPort spec.
G-Sync only works with NVIDIA cards, and only ever will.
Unlike G-Sync, Adaptive-Sync (FreeSync) should work with
any GPU that has a DP1.2a connection once they add driver support.
AMD is developing open standards that anyone can use (Adaptive-Sync, OpenCL, Mantle/Vulkan, HSA,
HBM, TressFX) while NVIDIA's approach is to lock down features to their own closed-off platform so that once you buy NVIDIA you won't want to switch away. (G-Sync, CUDA, PhysX, TXAA, GameWorks)
You shouldn't support that. And I say this as someone that has only bought Intel/NVIDIA hardware in the last five years.
Locked-down connections for peripheral devices like displays is where I draw the line.
It was different when G-Sync was the only option available, and it would be different if NVIDIA wanted G-Sync to be a competing standard to Adaptive-Sync if they believe that it offers a better experience.
But they are refusing to support open industry standards in favor of their own proprietary locked-down ones, and that's not OK.
What they should have done was support Adaptive-Sync and open up the G-Sync spec so that it could be supported on AMD/Intel GPUs and they still get their $100 or whatever it is on every monitor sold, if people believe that G-Sync offers a superior experience to Adaptive-Sync. But I expect that there won't be many G-Sync displays available a few years from now once everything gets Adaptive-Sync for "free", and NVIDIA will be forced into supporting it.
