Sony’s PS5 SSD has “raw bandwidth higher than any SSD available for PCs”

Technical particulars about Sony’s next-gen PS5 console have been dribbling out for some time. But, whereas most have centred across the AMD Ryzen-powered APU, and Navi GPU at its coronary heart, a brand new briefing with Sony’s Mark Cerny has delivered some probably stunning data concerning the storage being constructed into the Playstation 5. He’s claiming that it’s not simply any SSD, however an SSD with greater potential bandwidth than something the huumble PC can at present handle.

We already know that the PS5 goes to ship with AMD because the silicon brains of the operation, probably with a Zen 2 CPU part and 7nm AMD Navi graphics half. Indeed the reported Gonzalo APU has been leaked through choose product codes and the technological particulars that they infer.

The customized Navi GPU Sony is utilizing can also be confirmed to be powering the ray tracing efficiency of the brand new PlayStation console, and never only for the visuals both. Cerny additionally means that audio ray tracing can be utilized for detailed, positional sound in games too.

Given that the PS5 APU will seemingly have AMD’s TrueAudio silicon baked into the design, the customized audio processing ought to assist with that. Even if the mid-range Navi GPU itself may battle to actually nail the form of demanding real-time ray tracing that’s bringing something exterior of Nvidia’s RTX cards to their knees. In reality a great deal of these RTX playing cards battle too…

But it’s Mark Cerny’s feedback within the new Wired article concerning the SSD efficiency of the brand new PlayStation 5 that’s the most attention-grabbing factor to come back out of the piece. He calls the PS5’s stable state drive “the key to the next generation.”

That’s fairly a declare, and one seemingly borne out by a side-by-side demo of a PS4 Pro and an early ‘low-speed’ devkit machine with an SSD inside it. Cerny demonstrates the improved load instances utilizing Spider-Man’s fast-travelling system – on the PS4 Pro it takes 15 seconds to load into the brand new space, whereas on the devkit it takes simply 0.eight seconds.

Cerny additionally demonstrates the advantages of an SSD on the subject of loading within the visuals of a brand new space on one thing just like the expansive open world of Spider-Man. Well, as expansive because the Manhattan cityscape will be, in any case.

The Wired piece says Sony hasn’t given any technical particulars concerning the SSD itself, resembling who makes the controller or NAND flash reminiscence, and even whether or not it’s utilizing the PCIe 4.Zero interface, however does say that “it has a raw bandwidth higher than any SSD available for PCs.”

“The raw read speed is important,” says Cerny, “but so are the details of the I/O mechanisms and the software stack that we put on top of them. I got a PlayStation 4 Pro and then I put in a SSD that cost as much as the PlayStation 4 Pro—it might be one-third faster.”

So it’s not only a query of merely slapping an SSD into the system, Sony is claiming that it, presumably alongside AMD, has developed the enter/output system to supply one thing over and above what you’d get from merely dropping some NAND flash right into a console.

Given that the following technology of AMD Ryzen 3000 CPUs, and the upcoming Navi GPUs, are anticipated to each be working on the PCIe 4.Zero interface these claims of Sony’s PS5 SSD providing larger uncooked bandwidth than something on the PC for the time being make sense. Realistically that’s seemingly solely to be a declare it will possibly make till AMD does launch the brand new CPUs and accompanying X570 motherboards with their PCIe 4.Zero help.

The new PCIe interface provides twice the theoretical bandwidth of PCIe 4.0, so the PC received’t be left behind on the subject of uncooked efficiency.

What may influence it, nevertheless, is the truth that PS5 builders will be capable of depend on a sure stage of storage efficiency from their {hardware}. A stage of efficiency that they received’t have skilled on consoles earlier than, and can’t depend on on the subject of PC game improvement both.

That may find yourself in some extremely wealthy, detailed, huge gameworlds, all with none loading screens breaking that sense of immersion. When you’ve nonetheless bought some PC players nonetheless working from anachronistic spinning knowledge platters that’s not essentially one thing that might be matched by default on any subsequent PC port.

That, greater than something the PS5’s AMD GPU or CPU efficiency can provide, may make the next-gen console’s games extra superior than your commonplace PC gaming fare.
