Let’s take into consideration this. Disappointing because it may be, we’re not getting a brand new PlayStation or Xbox in 2019. There are a variety of explanation why. (And should you for certain know of a selected motive, you need to DM me, electronic mail me, or tip us safely and securely through SecureDrop.) However I’ve been eager about this fairly a bit, and I feel I’ve found out no less than one superb motive. AMD, Sony, and Microsoft all declined to talk about future merchandise once I requested them about this idea, however simply because they gained’t discuss to me about my idea, doesn’t imply it’s pointless. So what’s my idea? I feel the graphics structure Microsoft and Sony have to construct their consoles simply isn’t prepared but.
Now hear me out. Take a look at what we all know to this point:
1. Sony and Microsoft are utilizing the identical base GPU structure
We all know each consoles are based mostly on the RDNA structure produced by AMD(RDNA is ceaselessly used interchangeably with its inside codename, Navi, nonetheless, AMD has requested that we use RDNA to check with the structure and Navi to precise GPUs).
2. Each consoles will use ray tracing
We all know that each consoles will embrace for assist ray tracing, a elaborate type of lighting 3D modeling that traces every level of sunshine from a supply to the mannequin and creating rather more sensible photos. Sony introduced the assist for ray tracing again in April (whereas additionally detailing that the PS5 may have an 8-core CPU based mostly on AMD’s Zen 2 structure).
Microsoft introduced Mission Scarlett’s assist for ray tracing on Sunday. The corporate has supported ray tracing even longer. It first launched the DirectX Ray API in 2018. That API permits builders to introduce ray tracing into functions for the Xbox, Home windows 10, or each.
3. Ray tracing is absolutely onerous to do
We all know that ray tracing seems very cool however usually requires {hardware} acceleration as a result of this can be very demanding on the GPU. When Nvidia rolled out the Turing structure final 12 months, it insisted ray tracing might solely be finished on client gadgets through {hardware} acceleration. This March, it lastly introduced software-based acceleration for its last-gen GPUs, however that type of ray tracing is extraordinarily restricted in comparison with what {hardware} accelerated GPUs can do. In a single occasion an Nvidia GTZ 1080Ti, which may sometimes do practically 100fps on Metro Exodus, dropped to under 20fps with ray tracing turned on.
It’s unlikely {that a} new console would come with ray tracing that’s software program accelerated.
4. 8K playback is difficult too
We all know that the Scarlett and the PS5 will assist 8K decision, which is extraordinarily demanding on the GPU. That could be a fairly tough process for a contemporary GPU to perform. The present AMD Radeon VII and Nvidia RTX 2080Ti each do between 60 and 70 fps on Far Cry 5 in 4K with max high quality. Double the decision would knock the framerate down considerably.
Now take into account ray tracing. We all know that the RTX 2080Ti can do 80 to 90 frames per second in Battlefield 5 at 4K decision. Turning ray tracing on drops that quantity to 64 frames per second. And that’s the most effective playing cards with ray tracing obtainable proper now! AMD isn’t even doing ray tracing but so we are able to’t choose how a lot the framerate will drop on a RDNA based mostly GPU with ray tracing turned on. We are able to assume it will likely be the same 20 to 30fps drop.
5. A model of RDNA that may do all of it gained’t be obtainable till 2020
We all know that the present technology of RDNA most likely can’t do all of that. Earlier this week I attended a collection of briefings for the press by AMD. It confirmed off the capabilities of RDNA and boasted that it will likely be simply as quick as Nvidia’s Turing whereas utilizing much less vitality and taking over much less area on a board. Notably, the model of RDNA confirmed off doesn’t embrace hardware-based acceleration for ray tracing, which I feel it must deal with ray tracing and the opposite calls for Sony and Microsoft have manufactured from the GPU.
And we all know that the model of RDNA that may theoretically deal with all of it, gained’t be obtainable till 2020. When the corporate outlined its imaginative and prescient for ray tracing, AMD’s David Wang, Senior VP of Engineering, made it very clear that the present technology of RDNA isn’t able to {hardware} acceleration. In line with Wang, that technology of RDNA gained’t even be obtainable till 2020.
This issues! {Hardware} acceleration is significant if a GPU needs to have the ability to keep the opposite taxing options, like 8K or 120fps assist. These consoles are purported to final for years to come back, and in the event that they’re choking on content material out of the gate, they’ll be a depressing set of gaming decisions for any of us to play.
I might be incorrect about all of this. Presumably the PS5 and Mission Scarlett have been in improvement for a while now, as the businesses should construct the customized chips based mostly on AMD structure first, then check them to ensure they work virtually completely, after which create developer kits so recreation builders can really get their fingers on the structure and develop for the rattling issues. That must be taking place proper now if these firms wish to have a bunch of attractive video games prepared by launch in late 2020.
However, as one recreation developer acquainted with growing for a number of platforms informed me (the sources on this story got anonymity as they aren’t licensed to talk with out PR current), “It’s true that video games can’t depend on the {hardware} being obtainable, so non-ray traced fallbacks should be created and maintained.” What they imply is that some stuff should be developed now with the hopes of {hardware} ultimately being obtainable. “[I]t’s simply part of doing enterprise for the time being that it’s a must to write graphics to each ray traced and non-ray traced APIs,” they added.
Which implies that ray tracing model of RDNA might be the factor Sony and Microsoft are ready for, and one of many issues holding their consoles again.
Much less of a working idea is one other AMD declare.: The corporate says that utilizing the identical structure on the PS5, Mission Scarlett, and future PC gaming machines advantages not simply builders but in addition players that play their video games. The declare was a major a part of the story the corporate pushed when briefing me on Zen 2 and RDNA.
AMD hopes that even when its components don’t beat rivals from Intel and Nvidia in fundamental benchmarks, that we’ll put money into them as a result of future video games are being constructed on its structure.
Two totally different recreation builders acquainted programming for a number of platforms informed me that AMD was basically proper. “Sure and no,” stated one. “It’s a spectrum for certain.” The issue is whereas the architectures are the identical, there shall be little quirks to every system. It’s not, for builders, all one system. They nonetheless should code for the PS5, and Mission Scarlett, and the myriad of playing cards and CPUs based mostly on RDNA and Zen 2.

Ray tracing will additional complicate that. If firms wish to implement it, they’ll should do a model for the Nvidia playing cards already supported, and for every next-gen console, and for the playing cards AMD ultimately produces. One developer informed me which means that even when ray tracing comes, it gained’t essentially be as spectacular because the hype claims. “[S]ince not all distributors agree about what number of recursive rays you may depend upon being supported and so on, there’ll nonetheless be some improvement in the direction of a “lowest supplied assist.”
