Engineering boards for GPUs are fairly fascinating. We get to see them listed & examined in leaks on a regular basis however solely on a couple of uncommon events will we get to see what they really seem like. Properly, we may be a bit fortunate as we speak as a number of AMD engineering boards that have been used to check and validate its Vega and Polaris GPUs, have appeared on numerous channels.
AMD Engineering Boards For Vega and Polaris GPUs Present Up – Early Validation & Testing Designs For Radeon RX Sequence Graphics Playing cards
There are an entire bunch of AMD GPU engineering boards which were noticed and we will begin off with the newest ones that are the Radeon RX Vega 64 and RX Vega 56 boards. It seems to be just like the Radeon RX Vega 64 engineering board is similar one which AMD used again at a press occasion held previous to the official unveiling of the cardboard at Capsacian & Cream, all the way in which again in February 2017.
You would possibly bear in mind the secondary PCB hooked up to the cardboard which was primarily used for the GPU verification and testing. The engineering board for the Vega 64 additionally featured an 8+6 pin config vs the twin 8-pin config on the ultimate variant. The remainder of the parts structure is precisely the identical as the ultimate variant. Some fascinating issues about this card are that it has a twin BIOS with one BIOS retaining the 300W TDP restrict and the opposite BIOS pushing the utmost TDP of the cardboard to 600W. However that is not helpful in any respect for the reason that card is locked to a default frequency of 1200 MHz. The PCB is listed to be produced in 2016 (twenty eighth week or July 2016).
Shifting on to the second Vega card, we’ve the Radeon RX Vega 56. This engineering board is of no shock because it was pictured some time after the discharge of the RX Vega 56 itself. Surprisingly, a triple fan variant wasn’t launched as a reference design by AMD however the crimson workforce did take some design inspiration of this cooling design for its Radeon VII graphics card.
We get a extra detailed have a look at the cardboard and its inside. Initially, the Radeon RX Vega 56 was meant to supply a a lot smaller PCB footprint than the RX Vega 64. This design would ultimately be adopted by a number of AIB companions of AMD however not AMD themselves. The triple-fan design might look generic however below the hood was a really spectacular heatsink design with a big aluminum fin block which was geared up with 4 thick copper warmth pipes working from the beginning and to the tip of the heatsink block. The GPU and VRAM made direct contact with the copper base.
Subsequent up, we’ve two very related wanting engineering boards for 2 very completely different GPUs. The primary engineering board is the one for AMD’s Vega 12 GPU which has been listed on eBay for $799.99 US and is said to work completely. I would not personally advise anybody to purchase this GPU and for a number of causes. There isn’t any assure if the chip is certainly working completely and engineering boards do not often get the identical stage of driver assist as shopper / retail boards. The opposite factor is that the value is simply approach too excessive in case you’re contemplating this to by some means carry out actual nice which as a matter of truth, it does not.
The AMD Vega 12 GPU was designed solely for cellular platforms and that is the particular board it was examined on. The Vega 12 GPU comes with a single 4 GB HBM2 bundle on the identical interposer. This particular variant is the Vega 12 XLA chip with 1024 stream processors and never the upper finish XTA variant which options 1280 stream processors. As you’ll be able to see from the board itself, even mainstream and low-end GPUs should be examined in numerous environments and that is why take a look at boards akin to this one are geared up with such a high-end cooling design and triple 8-pin energy connectors.

And at last, the final board that we acquired to see is the one for the Radeon RX 560 which has additionally been used for testing out all the way in which from the bottom finish RX 540 (Lexa) GPUs to the highest-end RX 590 (Polaris 30) GPUs. This board would possibly look much like the one for the Radeon RX Vega 12 GPUs however could be very completely different on nearer inspection. The very first thing is the cooling design which is extra toned down in comparison with those for the Vega GPUs. We’re additionally taking a look at two twin 8-pin energy inputs vs 3 on the board for Vega. The PCB itself could be very enormous and has 5 show outputs.
Beneath the principle cooler is a chunk of copper CNC heatsink which makes contact with the VRAM however not all reminiscence dies are making excellent contact with the heatsink. The VRM is a 6+2 part structure with the IR3567B PWM controller. There are 4 reminiscence dies featured on this board that are 7 Gbps Samsung modules (128-bit / 4 GB). This mannequin can be listed at eBay for a price of $650 US.

On the finish of the day, these are some actually fascinating take a look at/engineering boards that present us how GPUs are examined previous to their launch within the shopper market and how much validation processes every chip has to undergo earlier than they find yourself in retail-ready graphics playing cards & discrete options.
