The tech specs for a Microsoft’s arriving Xbox Project Scorpio are here, pleasantness of Digital Foundry, and—on paper on least—Microsoft has hit a 6 teraflops opening idea for a console and afterwards some. If early opening in Forza and contrast by a association is anything to go by, Scorpio will play a good chunk of games during a local 4K fortitude and during 60FPS.
Even softened for gamers with a vast library of existent Xbox One games, the full energy of Scorpio can be “theoretically” be used to give comparison games a opening boost. While this doesn’t meant that comparison games will unexpected run during 4K or 60FPS, games that had issues regulating uniformly a Xbox One are expected to run as dictated on Scorpio.
“We’ve taken a proceed that we do with 360 [games] on Xbox One,” says Microsoft, “where we will never see a ripped frame, since we have adequate opening there to safeguard that.”
More bandwidth than a GTX 1080
At a heart of Project Scorpio is an all-new AMD GPU, that features 40 “customised” Radeon discriminate units (compared to usually 12 on a Xbox One and Xbox One S) clocked during an considerable 1172MHz. That’s a estimable boost over Xbox One GPU’s 853MHz time speeds, and even the PS4 Pro‘s 911MHz. Microsoft has doubled a volume of shader engines and describe back-ends, and quadrupled a GPU L2 cache size, that it claims has boosted a GPU fill-rate by 2.7x. That’s some-more than enough, it says, for local 4K gaming.
The new GPU—which still lives on a same die as a CPU—is interconnected with 12GB of GDDR5 memory, imprinting a pierce divided from a DDR3/ESRAM pairing of a Xbox One towards a one memory pattern lucky by Sony’s PlayStation 4. In theory, latency will be aloft compared to a Xbox One’s ESRAM, though Microsoft says that “in terms of sum performance, a softened bandwidth and softened GPU opening means we don’t strike any issues.”
That memory is divided adult into 12 1GB chips, any of that sports a 32-bit interface to emanate a 384-bit bus. In total, there’s 326GB/s of memory bandwidth, that is almost aloft than a 204GB/s of a Xbox One and a 218GB/s of a PS4 Pro. Indeed, it’s even aloft than AMD’s possess RX 480, and aloft than Nvidia’s top-of-the-line GTX 1080.
While 12GB of memory sounds like a lot, developers will usually have entrance to 8GB. The remaining 4GB will be dedicated to regulating a handling system, that Microsoft says is compulsory to run a dashboard during a local 4K resolution. That’s still 60 percent some-more memory than developers had entrance to in a past (the Xbox One indifferent 3GB for a OS), which—when interconnected with a enclosed 1TB tough expostulate with 50 percent some-more bandwidth—should safeguard 4K games bucket as fast as their HD counterparts according to Microsoft.
Naturally a CPU has been given a strike over a Xbox One too. It’s still an 8-core, X86-based chip, though it now runs during 2.3GHz (compared to 1.75GHz in a Xbox One and 2.1GHz in a PS4 Pro). Unlike a predecessor, that used AMD’s mobile-first “Jaguar” cores, Scorpio uses “custom” X86 cores, that are subsequent from Jaguar though heavily modified. Those awaiting Ryzen might be disappointed, though Microsoft claims a customisation work it undertook with AMD has resulted in cores that are “31 percent faster” than in a Xbox One.
“So, 8 cores, organized as dual clusters with a sum of 4MB of L2 cache. These are singular customised CPUs for Scorpio regulating during 2.3GHz. Alluding behind to a goals, we wanted to contend 100 per cent retrograde harmony with Xbox One and Xbox One S while also pulling a opening envelope,” Microsoft’s Nick Baker told Digital Foundry.
Not usually for 4K
While Scorpio’s energy is mostly directed during 4K gaming, there will be advantages for those with 1080p televisions. Supersampling—that is, digest a diversion during 4K before downsampling to a reduce resolution—will be supported. Microsoft has mandated to all developers that users should have a choice of 4K digest or softened 1080p performance, and that all games should run during a same frame-rate or aloft as on a standard Xbox One.
Dynamic fortitude scaling is mooted for existent games like Doom, Halo 5, Gears of War 4, Battlefield 1, Call of Duty: Infinite Warfare and The Division.
To assistance developers get a many out of Scorpio, Microsoft has changed a GPU authority processor—the hardware that takes instructions from a CPU and funnels them by to a graphics core—over to a DirectX 12-optimised solution. In theory, this will massively urge pull call opening on Scorpio, and cut down on CPU overheads.
“We radically changed Direct3D 12,” Microsoft told Digital Foundry. “We built that into a authority processor of a GPU and what that means is that, for all a high magnitude API invocations that a games do, they’ll all natively implemented in a proof of a authority processor—and what this means is that a communication from a diversion to a GPU is super-efficient.”
Aside from a title spec bumps, Scorpio has few other engaging additions. THere’s a new “spacial surround” feature, that adds a tallness member to an existent 7.1 set-up, that sounds eerily identical to Dolby Atmos. The media encoding hardware retard now supports a HEVC codec for 4K 60FPS recording in Xbox GameDVR, and there’s a new retroactive shade constraint underline that allows users to pierce by captures frame-by-frame to assistance take a best shot but pointing timing.
But what does it demeanour like?
Microsoft hasn’t nonetheless suggested what Scorpio looks like, other than to contend that it’s “trying to aim a compress design.” It has, however, suggested that it’s regulating a effluvium cover feverishness penetrate to keep a total CPU and GPU (APU) cool, identical to that employed by Nvidia in a Founders Edition graphics cards. Inside a feverishness penetrate is ionised strong H2O kept underneath a vacuum. Heat is engrossed into a water, that turns into steam, that afterwards condenses on a feverishness penetrate fans. That feverishness is afterwards diminished by a “custom designed blending centrifugal fan.”
Those disturbed that Scorpio’s additional horsepower would symbol a lapse to a most maligned outmost energy section of a strange Xbox One can rest easy—Scorpio will underline an inner 245W energy supply, finish with a same figure-eight energy hollow as a Xbox One S. While there’s naturally no lapse of a Kinect port, a UHD Blu-ray expostulate returns, as does a HDMI submit (yay?).
Scorpio’s final form cause will be suggested during this year’s E3.
