What GPU scarcity? AMD and Apple’s attractive new graphics card comes with two

One have a look at the Radeon Professional W6800X Duo and also you may be questioning, what occurred to the chip scarcity? Properly, it is nonetheless ongoing, but it surely appears AMD saved up a stash particularly for this dual-GPU RDNA 2 powerhouse earlier than you immediately. Constructed for Apple’s Mac Professional, the Radeon Professional W6800X Duo comes with two discrete RDNA 2 GPUs tangled along with AMD’s Infinity Material interconnect.

Is that this probably the most gorgeous PCB in PC {hardware} immediately? For me, it is a toss-up between this and the Intel Hades Canyon NUC PCB, which is a mini PC marvel if ever there was one. That additionally featured AMD Radeon graphics, funnily sufficient, however falls far wanting the efficiency on provide from the Radeon Professional W6800X Duo.

Every discrete GPU inside the Radeon Professional W6800X Duo shares its specification with the Radeon RX 6800, so you’ll be able to primarily copy and paste the high-end gaming chip to make up one Radeon Professional W6800X Duo.

One graphics card, two GPUs. Every one that includes 60 RDNA 2 CUs for a complete of three,840 cores per chip. That is 7,680 in complete, which for a little bit perspective is 50% extra cores than the Radeon RX 6900 XT.

The place the Radeon Professional card differs from Radeon gaming playing cards is reminiscence capability, which is commonplace process for a workstation card akin to this. There’s 32GB of GDDR6 reminiscence per GPU on the W6800X Duo, for a complete of 64GB.

All mounted on a single PCB. Which means elements akin to VRM, MOSFETs, capacitors, and all of the traces inside the PCB should even be doubled.

All of which sounds exceptionally sizzling and thirsty, and also you’d in all probability not be flawed. That is why the W6800X Duo is fitted inside Apple’s MPX Module, which is a specially-built unit that slots contained in the Mac Professional and incorporates as much as 500W of energy and Thunderbolt 3. Its top is predominantly made up of a heatsink, which takes benefit of the Mac Professional’s triple-fan design to maintain each chips cool.

Then you definitely get to the really wild bit: Apple will promote you a Mac Professional with two MPX Modules inside it. That is 4 GPUs inside a single machine.

‘Why?’, I hear you ask. The good thing about such a setup isn’t solely uncooked compute energy, but in addition extra bandwidth to match. Every W6800X Duo consists of an Infinity Material connection that straddles its two GPUs—one and the identical with the interconnect used to bridge chiplets inside AMD Ryzen Zen 2 and newer processors. It is the bandwidth on provide with that connection that gives excessive efficiency between the 2 GPUs and can save time when working compute-heavy duties.

Sadly, the times of dual-GPU gaming graphics playing cards have handed. The place as soon as drivers had been constructed to fulfill the wants of customers working both dual-graphics card or dual-GPU techniques, that is not usually the case immediately. In brief, this Radeon Professional Duo is not going to instantly make the Mac Professional a gaming monster. It may be a monster for making video games, no less than.

But that is to not say we cannot see one thing related in our gaming PCs. AMD is rumoured to be producing a graphics card with chiplets, one that may simply blur the traces of what constitutes a single GPU.

If these rumours are true, let’s hope AMD is a bit more beneficiant in relation to pricing than Apple. A Mac Professional with two Radeon Professional W6800X Duo MPX Modules begins out at $15,599—every W6800X Duo racking up $5,000.
