Let ’s think about this . dissatisfactory as it might be , we ’re not getting a new PlayStation or Xbox in 2019 . There are a lot of reasons why . ( And if you for indisputable know of a specific ground , you shouldDM me , email me , ortip us safely and firmly via SecureDrop . ) But I ’ve been think about this quite a snatch , and I think I have figured out at least one very estimable reason . AMD , Sony , and Microsoft all declined to speak about future products when I asked them about this hypothesis , but just because they wo n’t talk to me about my possibility , does n’t think of it ’s pointless . So what ’s my theory ? I call up the graphics architecture Microsoft and Sony need to build their consoles just is n’t ready yet .
Now hear me out . Look at what we know so far :
We love both consoles are based on theRDNA architecture produce by AMD(RDNA is frequently used interchangeably with its internal codename , Navi , however , AMD has require that we use RDNA to refer to the computer architecture and Navi to actual GPUs ) .

We know that both consoles willinclude for bread and butter ray tracing , a fancy signifier of lighting 3D modeling that traces each point of light from a author to the modeling and creating much more realistic image . Sony foretell the financial backing for re tracing back in April(while also detailing that the PS5 will have an 8 - core CPU establish on AMD ’s Zen 2 architecture ) .
Microsoft announce Project Scarlett ’s support for ray tracing on Sunday . The company has sustain ray tracing even longer . It first released the DirectX Ray API in 2018 . That API give up developers to insert beam hunt into coating for the Xbox , Windows 10 , or both .
We experience that shaft tracing looks very coolheaded but more often than not requires computer hardware quickening because it is super demanding on the GPU . When Nvidia rolled out the Turing architecture last twelvemonth , it insist ray trace could only be done on consumer equipment via hardware acceleration . This March , it lastly announced software - establish quickening for its last - gen GPUs , but that form of light beam trace is extremely limited liken to what computer hardware speed up GPUs can do . In one instance an Nvidia GTZ 1080Ti , which can typically do nearly 100fps on Metro Exodus , dropped to below 20fps with ray of light trace turned on .

It is unlikely that a new console table would include beam trace that ’s software accelerate .
We live thatthe Scarlettand thePS5 will support 8 K answer , which is extremely demanding on the GPU . That is a pretty hard task for a modern GPU to carry out . The currentAMD Radeon VIIandNvidia RTX 2080Tiboth do between 60 and 70 fps on Far Cry 5 in 4 K with Georgia home boy quality . Double the firmness of purpose would knock the framerate down importantly .
Now consider beam trace . We know that the RTX 2080Ti can do 80 to 90 frames per second in Battlefield 5 at 4 KiB resolution . turn ray tracing on drops that number to 64 frames per second . And that ’s one of the best batting order with beam of light tracing available right now ! AMD is n’t even doing ray of light trace yet so we ca n’t approximate how much the framerate will drop on a RDNA base GPU with ray trace turned on . We can presume it will be a like 20 to 30fps drop .

We know that the current generation of RDNA probably ca n’t do all of that . in the beginning this calendar week I attended a series of briefings for the press by AMD . It bear witness off the capabilities of RDNA and boasted that it will be just as tight as Nvidia ’s Turing while using less Energy Department and taking up less outer space on a board . Notably , the variation of RDNA showed off does n’t let in computer hardware - based acceleration for beam of light trace , which I think it need to handle irradiation trace and the other demand Sony and Microsoft have made of the GPU .
And we know that the version of RDNA that can theoretically handle it all , wo n’t be useable until 2020 . When the company outlined its sight for shaft of light trace , AMD ’s David Wang , fourth-year VP of Engineering , made it very vindicated that the current generation of RDNA is n’t adequate to of hardware acceleration . According to Wang , that generation of RDNA wo n’t even be usable until 2020 .
This topic ! computer hardware acceleration is vital if a GPU wants to be able to maintain the other taxing features , like 8 K or 120fps funding . These consoles are suppose to last for long time to hail , and if they ’re choking on content out of the gate , they ’ll be a miserable set of gaming choices for any of us to play .
I could be incorrect about all of this . Presumably the PS5 and Project Scarlett have been in development for some time now , as the party have to build the customs duty fries based on AMD architecture first , then test them to verify they do work much perfectly , and then create developer kits so game developers can really get their hands on the architecture and explicate for the damn things . That needs to be happening right now if these companies need to have a bunch of gorgeous games ready by launch in tardy 2020 .
But , as one game developer conversant with developing for multiple platforms told me ( the sources in this write up were reach namelessness as they are not authorized to speak without PR present ) , “ It ’s rightful that games ca n’t rely on the hardware being available , so non - ray follow fallbacks have to be create and maintained . ” What they mean is that some stuff will have to be developed now with the hopes of hardware eventually being useable . “ [ I]t ’s just a part of doing business at the moment that you have to write nontextual matter to both ray traced and non - ray line APIs , ” they added .
Which means that electron beam decipher version of RDNA could be the thing Sony and Microsoft are wait for , and one of the things hold up their consoles back .
Less of a working possibility is another AMD claim . : The troupe says that using the same computer architecture on the PS5 , Project Scarlett , and future microcomputer gaming machine benefits not just developer but also gamers that play their games . The claim was a significant part of the story the company agitate when briefing me on Zen 2 and RDNA .
AMD hopes that even when its character do n’t beat rivals from Intel and Nvidia in canonic benchmark , that we will invest in them because future games are being built on its architecture .
Two different game developers familiar programming for multiple weapons platform recite me that AMD was essentially veracious . “ Yes and no , ” suppose one . “ It ’s a spectrum for certain . ” The problem is while the computer architecture are the same , there will be little quirks to each organization . It ’s not , for developer , all one system . They still have to code for the PS5 , and Project Scarlett , and the myriad of card and central processing unit establish on RDNA and Zen 2 .
Ray trace will further rarify that . If company want to implement it , they ’ll have to do a translation for the Nvidia card already stomach , and for each next - gen console , and for the cards AMD eventually produces . One developer tell me this intend that even when irradiation tracing comes , it wo n’t necessarily be as salient as the hoopla claim . “ [ S]ince not all vendors correspond about how many recursive rays you may depend on being supported etc , there will still be some growth towards a “ abject offered supporting . ”
There are likely quite a few reasons these consoles are n’t coming until 2020 , but the indigence for ray trace musical accompaniment , which is clear lacking in the computer architecture we ’ve see so far , seems like at least one very salutary reason while we ’ll have to wait .
