PS5 & Xbox Series X specs: the next-gen console features coming to gaming PCs


With Microsoft asserting the Xbox Sequence X tech spec on Monday, and almost as we teach adopted by a seminar from Sony on the technical minute print of the PlayStation 5, we now enjoy a quantifiable records on these rival companies’ most efficient laid plans and a rough belief of whereabouts their programs will land in phrases of efficiency. What we ingredient in dazzling but, nonetheless, is both Sony and Microsoft’s secret herbs and spices mix – that is to claim, all that custom silicon they’re brandishing.

I’m in a position to’t declare I’m deal surprised that both Sony and Microsoft are throwing the discover ‘custom’ spherical a lot this generation. We’ve identified for some time that the Xbox Sequence X and PS5 specs encompass custom AMD Zen 2 and RDNA 2 silicon. Obvious, the configurations are diversified – the Sequence X will reach with 52 CUs at 1.825GHz to the PS5’s 36 CUs at 2.23GHz – nonetheless the core structure, the core technology and process, are by-and-loyal equivalent. That’s moreover the equivalent tech that is either extant (Zen 2 CPUs) or soon to advance (RDNA 2 GPUs) for our gaming PCs, too.

So when these two goliaths of gaming technology go head-to-head, PS5 vs. Xbox Sequence X, in a battle of tech specs, the focus has shifted faraway from resolutions and frames per 2d and onto custom processors and specialised silicon. But that doesn’t basically point out we received’t survey any of this proprietary tech headed to our gaming PCs within the reach-future – with out a doubt, rather the reverse.

Make a selection, for instance, the Sequence X’s Xbox Prance Structure. This cache-busting technology consists of four elements: an NVMe SSD, a dedicated hardware decompression block, the DirectStorage API, and Sample Solutions Streaming (SFS). Obviously you don’t need me to affirm you that a form of elements is already embedded into the PC ecosystem – NVMe drives are ubiquitous across the most efficient SSDs for gaming at this level.

That DirectStorage API, too, is headed for our PCs. Devour that. As a portion of Microsoft’s bundle of DirectX products, the company will be bringing its redesigned I/O system to Home windows for all to revel in.

“As much as date video games assemble asset streaming within the background to continuously load the following elements of the arena while you play,” an Xbox weblog submit reads, “and DirectStorage can lower the CPU overhead for these I/O operations from extra than one cores to taking dazzling a minute portion of a single core – thereby freeing substantial CPU vitality for the game to use on areas like greater physics or extra NPCs in a scene.

“This most well liked member of the DirectX family is being supplied with the Xbox Sequence X and we conception to assert it to Home windows as wisely.”

DirectStorage will lower the CPU overhead required by I/O operations to a portion of their favorite put a matter to, leaving extra of the Sequence X’s eight Zen 2 cores free to work on diversified initiatives. The same would possibly presumably be said for a gaming PC, too.

Shifting load faraway from the CPU will relieve to steal bottlenecks from an older system, nonetheless the gash worth in overhead will moreover enable developers to program titles to originate greater employ of CPU threads going spare.

Equally, Sampler Solutions Streaming is available on PC on the present time. It’s now a portion of the DirectX 12 Closing API, which changed into as soon as announced dazzling yesterday, and serves to toughen texture streaming (pulling in textures on-put a matter to) and texture-home shading. All of which is precious for rendering at excessive resolutions, in particular 4K. Enhance received’t be limited to AMD RDNA 2, either. Nvidia RTX 20-sequence graphics playing cards constructed on the Turing structure equally possess the necessary hardware to totally-enhance the DX12 U specification, which contains DirectX Raytracing 1.0 and 1.1, sampler suggestions, mesh shaders, and variable price shading. Intel’s moreover touting enhance for some of these aspects in my knowing with Intel Xe – it’s a free-for-all.

So as that Xbox Prance Structure? We’ll be basking in most of these optimisations on PC within the reach-future. It’s most efficient the dedicated hardware decompression chip that we’re lacking, which equally reduces CPU utilization for decompression initiatives by redistributing that operation from the CPU and onto dedicated silicon. That’s fully now not out of the realms of chance for CPUs with on-chip (or chiplet) I/O functionality increasing, nonetheless.

The dedicated hardware decompression chip is a goal stumbled on across both Xbox Sequence X and PS5 blueprints, to this level. Whereas Xbox is using BCPack, Sony’s PS5 is using Kraken decompression technology (from RAD Game Tools) within its system, which affords up to 10% increased compression efficiency for records, and location to be bolstered by dedicated hardware blocks.

Sony’s integrating the custom decompression chip alongside a dedicated DMA controller, two I/O co-processors, coherency engines, and GPU cache scrubbers. That’s quite a lot of proprietary tech, nonetheless that doesn’t basically point out we received’t survey some of Sony’s work filter into our gaming PCs.

“AMD is continuously bettering and revising their tech,” Impress Cerny, lead system architect for PS5, says. “For RDNA 2, their targets enjoy been, roughly talking, to lower vitality consumption by architecting the GPU to build records where it’s wanted, to optimise the GPU for efficiency, and in an effort to add a brand new, extra developed, goal location. But that goal location is malleable, which is to claim we now enjoy our private wants for PlayStation and that can ingredient into what the AMD roadmap turns into.

“So collaboration is fashioned. If we assert ideas to AMD which will seemingly be felt to be widely helpful, then they will even be adopted into RDNA 2 and venerable broadly, including PC GPUs. If the guidelines are sufficiently explicit to what we’re attempting to attain, just like the GPU cache scrubbers I changed into as soon as talking about, then they prove being dazzling for us. In case you survey a equivalent discrete GPU available as a PC card at roughly the equivalent time as we free up our console, which technique our collaboration with AMD succeeded in producing technology in both worlds. It doesn’t point out we simply incorporated a PC portion into our console.”

All that appears to be like like a promise of a truly equivalent discrete graphics card filled with on the least some of the aspects Sony outlined all the tactic thru its tech specs deep dive. And all launching at roughly the equivalent time because the PS5 (anticipated sometime in Q4). Merely steer clear of Sony’s scrubbers, ya hear!?

So many of these vital cache, I/O, and storage applied sciences underpinning both the Xbox Sequence X and PlayStation 5 efficiency later this 300 and sixty five days will originate their technique over to PC gaming. There’s serene that petite topic of whether or now not or now not developers will decide to program for them across platforms – or at all – nonetheless consoles are mighty proposition and a guaranteed viewers, so it’s seemingly extra than dazzling Sony and Microsoft’s first-social gathering studios will try to integrate all the tactic thru these consoles’ lifetimes.

Onwards to audio. 3D audio engines enjoy become a focus for both console producers with this generation, worthy extra so than with the closing. The Xbox Sequence X will goal a dedicated audio block on-chip intended to vitality ‘Venture Acoustics’, which simulates wave effects in advanced geometries to extra precisely painting sounds because it’s a long way also heard by the human ear in terms of nearby objects.

The PS5’s dedicated audio chip has been outlined in a petite of extra detail, and Sony is specializing in “presence and locality” with its onboard ‘Tempest 3D AudioTech’ algorithms and engine. The hardware block element itself is something that would possibly presumably theoretically be applied hasty on PC – even within AMD’s RDNA 2 GPUs. That’s because of Sony’s engine is a re-purposed GPU CU. An RDNA 2 compute unit. There’s nothing rather like a most up-to-date GPU CU to work on a extremely-parallel job.


Attributable to the close collaboration with Sony, we wouldn’t be deal surprised to survey AMD pulling this goal out of the console skunkworks and integrating it into its private discrete GPU product stack with Navi 2X. Cerny changed into as soon as cautious to most efficient name the algorithms Sony’s working with Tempest “proprietary”. But let’s moreover undergo in tips that 3D audio engines and HRTF (Head Connected Switch Aim) processing are now not a brand new to PC gaming, and are in most cases delivered through utility in-sport and processed through CPU thread utilisation. A unusual hardware integration would rather relieve to streak 3D and spatial audio processing and steal CPU load, potentially allowing customers beforehand unable to make employ of deeper audio processing to develop so.

Each and every Xbox and Sony enjoy expressed a desire to enable developers to originate video games and worlds freely and with out peril across their programs. With DX12 U and Vulkan laying the foundations of that promise with near the steel programming across the Xbox Sequence X and PS5 respectively, this console generation would possibly presumably be the most versatile but. That every serves to relieve PC gaming, as developers are in a position to salvage true of entry to a worthy greater, defective-platform, viewers with the one stroke of a brush.

With one foot in AMD RDNA 2, and one other in proprietary hardware blocks, the following-generation consoles from both Sony and Xbox most efficient relieve to lift the bar for gaming efficiency across the board. That’s moreover a boon to our rather scalable gaming rigs. It feels like quite a lot of what’s to reach within the PS5 and Xbox Sequence X is determined for a PC debut at some level or one other – and who knows what else AMD, and Nvidia, enjoy cooking up for the tip of 2020 and heading into 2021.
