AMD's next-gen GPUs could embrace DisplayPort 2.0 for 8K HDR play
There is understanding to believe AMD might support the updated DisplayPort 2.0 specification with its next-generation graphics cards supported RDNA 3. If that comes to pass, it could pave the way for uncompressed 8K gaming in HDR, though we'rhenium getting a bit onwards of ourselves.
What's at play here are half a dozen new patches to AMD's open rootage unified graphics number one wood for Linux (AMDGPU). The latest patches (via Phoronix) come from AMD, and they add support for the DisplayPort 2.0 communications protocol.
The Video Electronics Standards Association (VESA) really announced the DisplayPort 2.0 specification a little over two years ago, so followed that up last year by adding an Alternate Mode (or Alt Mode) standard to the mix to furnish "seamless interoperability with the new USB4 specifications published past the USB Implementers Forum (USB-IF)."
Alt Modality essentially enables all of the features of DisplayPort 2.0 through a USB Type-C connector, to split the bandwidth betwixt video recording and information, if desired. And it is the bandwidth hit that is a big deal here.
DisplayPort 2.0 can deliver a maximum payload of up to 77.37 gigabits per second across four lanes (up to 19.34Gbps per lane), versus 48Gbps for HDMI 2.1. Without introducing compression, that's enough to feed up to a 10K closure presentation at 60Hz, or an 8K display at 60Hz with full-color 30 bpp 4:4:4 HDR.
Introducing what's called Display Flow Compaction (DSC) enables symmetric higher resolutions and refresh value combos—in that location's enough bandwidth to drive a 16K display (15360x8460) at 60Hz, too with full-color 30 bpp 4:4:4 HDR.
Both the monitor and graphics card need to underpin DisplayPort 2.0 in order to tap into all this bandwidth. Now, neither exist in the consumer space. Information technology looks like that could change next twelvemonth, though.
Back in January, VESA told our friends at Tom's Hardware that the pandemic postponed the timeline for getting DisplayPort 2.0 products into the wild.
"What's rather created a delay is the Covid-19 situation," explained Craig Wiley, a representative for VESA. "What normally happens is that companies get together and exam hardware among themselves to bridle verboten interoperability between a PC and a video display. As a matter of fact, VESA has test events we call PlugTests, typically two or tercet a year. Only we had none in 2020. This has caused a wait in debugging and developing."
At the time, Wiley said he expects DisplayPort 2.0 products would arrive sometime in the second fractional of this year. If that is the case, it almost unquestionably substance we are looking at DisplayPort 2.0 monitors arriving first, since we're not aware of any star GPU launches regular for this year.
Looking ahead, AMD's next-gen GPUs could support DisplayPort 2.0, and we wouldn't be surprised if Nvidia embraced the common next class besides. Of line, the other incline of the equation is delivering enough GPU horsepower to drive ultra-high resolution gaming.
We've only newly gotten to the point where comfortably gambling at 4K is feasible, though it still requires high-close hardware and/or upsampling routines look-alike Nvidia's DLSS 2.0 and AMD's FidelityFX Super Resolution (Intel volition also implement some kind of supersampling proficiency with its upcoming Alchemist GPUs).
So while DisplayPort 2.0 will provide other way to 8K gambling, IT remains to be seen if next year's GPUs will actually make up equal to the labor.
Paul has been acting PC games and raking his knuckles on computing device hardware since the Commodore 64. He does not bear any tattoos, only thinks information technology would be cool to get one that reads LOAD"*",8,1. In his off clock time, he rides motorcycles and wrestles alligators (only one of those is true).
