AMD has confirmed that its subsequent era graphics playing cards will assist DisplayPort 2.0 straight out of the field, for all of your HDR, high-res, excessive refresh charge gaming wants. There was already the suggestion that new graphics playing cards from AMD and Nvidia would assist the brand new commonplace, particularly as Intel has already confirmed its delayed desktop GPUs will do, however that is the primary official affirmation we have had from the pink staff itself.
That got here throughout AMD’s VP of graphics engineering, David Wang’s discuss throughout its monetary analyst day, where he went into some very gentle element in regards to the firm’s graphics tech going ahead.
He gave us the primary hints of what we will count on from the brand new applied sciences being baked into the upcoming RDNA 3 GPUs although did not actually do way more than hit a couple of advertising and marketing bullet factors on his approach down the record. Yes, we’re getting chiplets “to continue to scale performance aggressively without the yield and the cost concerns of large monolithic silicon,” however that is about it.
He additionally touched on some potential modifications to the way in which the revised compute models, or workgroup models, operate and an alteration to the graphics pipeline which may enable it to do hybrid real-time ray tracing with out the efficiency hit you at present get on RDNA 2 silicon.
Though once more, it was obscure and given treasured little element.
What was concrete, nevertheless, was the affirmation of DisplayPort 2.0 assist for RDNA 3 graphics playing cards: “We’ll also augment our display capabilities with the new DisplayPort 2 standard,” says Wang, “to support upcoming HDR displays with high resolutions and refresh rates.”
Why is that vital? Well, arguably it isn’t. Yet. DP 2.0 gaming displays are nonetheless unavailable, and with Samsung already placing its HDR 2000, 240Hz 4K Odyssey Neo G8 up for pre-order with out DisplayPort 2.0 connections, you possibly can say that its potential is proscribed.
The Samsung display makes use of Display Stream Compression to ship a 240Hz 4K expertise, regardless of HDMI 2.1 being theoretically restricted to 144Hz at that decision. According to its proponents it should not end in any lack of color despite the fact that it’s compressed, however having the ability to ship a full uncompressed stream is the actual promise of DisplayPort 2.0.
With a full 80Gbps of bandwidth—in comparison with 48Gbps with HDMI 2.1—you have got simply sufficient bandwidth to deal with the heavy calls for of a real 4K 240Hz sign. That full knowledge stream would require round 72Gbps, nearly on the very limits of even the brand new DP commonplace.
AMD assist for DisplayPort 2.0 was beforehand hinted at in open-source driver particulars, and Nvidia can be extensively anticipated to incorporate the usual in its Lovelace era of GPUs later this 12 months, too. Fingers crossed we truly begin to see some shows which take benefit across the identical time.
