Have a look at the Radeon Pro W6800X Duo and you may be wondering what happened to the shortage of chips? Well, it’s still underway, but it looks like AMD has saved a specific reservation for this dual-GPU RDNA 2 core before you. Built for Apple’s Mac Pro, the Radeon Pro W6800X Duo comes with two discrete RDNA 2 GPUs tangled with AMD’s Infinity Fabric interconnect.
Is it the most impressive PCB of today's PC hardware? To me, it's a disagreement between that and the Intel Hades Canyon NUC PCB, which is a wonder of the mini PC if it ever existed. It also featured AMD Radeon graphics, in a fun way, but it’s within walking distance of the performance the Radeon Pro W6800X Duo offers.
Each unobtrusive GPU in the Radeon Pro W6800X Duo shares its specifications with the Radeon RX 6800, so you can basically copy and paste the high-end gaming chip to form a Radeon Pro W6800X Duo.
One graphics card, two GPUs. Each includes 60 CU RDNA 2 for a total of 3,840 cores per chip. There are 7,680 in total, which for some perspective means 50% more cores than the Radeon RX 6900 XT.
When the Radeon Pro card differs from Radeon gaming cards it is the memory capacity, which is a standard procedure for a workstation card like this. There is 32GB of GDDR6 memory per GPU in the W6800X Duo, for a total of 64GB.
All mounted on a single PCB. This means that components such as VRM, MOSFET, capacitors and all traces of the PCB must also be duplicated.
This all sounds exceptionally hot and thirsty, and you probably won’t go wrong. That's why the W6800X Duo is part of Apple's MPX module, which is a specially built unit that includes slots inside the Mac Pro and incorporates up to 500 W of power and Thunderbolt 3. Its height consists mainly of a heatsink, which takes advantage of the Mac Pro's triple fan design to keep both chips cool.
Then you get to the really wild look: Apple will sell you a Mac Pro with two MPX modules inside. Of course four GPU inside a single machine.
"Why?" I hear you ask. The advantage of this configuration is not only the raw computing power, but also the most suitable bandwidth. Each W6800X Duo includes an Infinity Fabric connection that straddles its two GPUs, one and the same, with the interconnection used to connect AMD Ryzen Zen 2 chipsets and newer processors. It is the bandwidth that is offered with this connection that offers high performance between the two GPUs and will save time when performing heavy computational tasks.
Unfortunately, the days of dual GPU gaming graphics cards are over. When drivers were once built to meet the needs of users using dual graphics card or dual GPU systems, this is not usually the case today. In short, this Radeon Pro Duo will not suddenly turn the Mac Pro into a gaming monster. It can be a monster to manufacturing games, at least.
Still, that doesn’t mean we won’t see something similar on our gaming computers. It is rumored that AMD is producing a graphics card with chips, which can only blur the lines of what constitutes a single GPU.
If these rumors are true, we expect AMD to be a little more generous in setting prices than Apple. A Mac Pro with two MPX modules Radeon Pro W6800X Duo starts at $ 15,599—Each W6800X Duo accumulates $ 5,000.
