If, to you, the word "unpredictable" sounds like a positive attribute for a graphics card, ASRock has something you may want. ASRock used words like “unpredictable” and “mysterious” for its new Phantom Gaming official trailer, two adjectives used to describe an upcoming series of AMD Radeon-equipped graphics cards. This is ASRock’s first time entering the graphics card space, where the company’s PCB designers will be faced with new challenges for AMD RX Vega GPUs (and future architectures).
The branding is for “Phantom” graphics cards, and the first-teased card appears to be using a somewhat standard dual-axial fan design with a traditional aluminum finstack and ~6mm heatpipes. Single 8-pin header is shown in the rendered teaser card, but as a render, we’re not sure what the actual product will look like.
AMD’s partner cards have been on hold for review for a while now. We first covered the Vega 64 Strix when we received it, which was around October 8th. The PowerColor card came in before Thanksgiving in the US, and immediately exhibited similar clock reporting and frequency bugginess with older driver revisions. AMD released driver version 17.11.4, though, which solved some of those problems – theoretically, anyway. There are still known issues with clock behavior in 17.11.4, but we wanted to test whether or not the drivers would play nice with the partner cards. For right now, our policy is this: (1) We will review the cards immediately upon consumer availability or pre-order, as that is when people will need to know if they’re any good; (2) we will review the cards when either the manufacturer declares them ready, or at a time when the cards appear to be functioning properly.
This benchmark is looking at the second option: We’re testing whether the ASUS Strix Vega 64 and PowerColor Red Devil 64 are ready for benchmarking, and looking at how they match versus the reference RX Vega 64. Theoretically, the cards should have slightly higher clocks, and therefore should perform better. Now, PowerColor has set clock targets at 1632MHz across the board, but “slightly higher clocks” doesn’t just mean clock target – it also means power budget, which board partners have control over. Either one of these, particularly in combination with superior cooling, should result in higher sustained boost clocks, which would result in higher framerates or scores.
Early reports surrounding Vega GPU packaging indicated minimally two different package processes, though later revealed a potential third. For the two primary forms of Vega GPU packaging, we’re looking at clear, obvious differences in assembly: The silicon (GPU + HBM) is either encased in an epoxy resin (“molded”) or is not encased at all (“resinless”). There is another type of resinless package that has been shown online, but we haven’t yet encountered this third type.
The initial concern indicated that packaging process could impact HBM2 contact to cooler coldplates – something for which, after working on this content, we later discovered new data – and we wanted to test that mounting pressure. Just last night, days after we finalized this content piece, we found another data point that deserves a separate article, so be sure to check back for the follow-up to this piece.
In the meantime, we’re using a chemically reactive contact paper to test various Vega GPUs and vapor chambers or coolers, then swapping coolers between those various GPUs to try and understand if and when differences emerge. Some brief thermal testing also helps us validate whether those differences, which would theoretically be spurred-on by packaging variance, are actually relevant to thermal performance. Today, we’re testing to see the mounting pressure and thermal impact from AMD’s various Vega 56 & 64 GPU packages, with a brief resurrection of the Frontier Edition.
Note: We used torque drivers for the assembly, so that process was controlled for.
AMD-exclusive partner XFX announced its competition to ASUS' still might-be-out-some-day-maybe Vega 64 Strix video card. At this point in time, partner cards still feel something like super cars: Nice to look at, probably won't own it.
But they're coming, so we're told, and the new target time seems to be "sometime in November." AMD partners have largely indicated supply issues of the Vega GPUs as the limiting factor of card presence on the market. The supply should build-up at some point, it's just a matter of if partners can secure a restock date to build confidence with retailers and distributors.
AMD’s newest driver pack should resolve player-reported issues of Destiny 2 crashes with AMD Vega hardware, including RX Vega 56 and RX Vega 64. The crash occurred during specific missions within Destiny 2, including the sixth mission (Exodus) and when nearing Nessus.
We received an email from AMD earlier notifying us of the new drivers, which can be found here.
AMD’s High-Bandwidth Cache Controller protocol is one of the keystones to the Vega architecture, marked by RTG lead Raja Koduri as a personal favorite feature of Vega, and highlighted in previous marketing materials as offering a potential 50% uplift in average FPS when in VRAM-constrained scenarios. With a few driver revisions now behind us, we’re revisiting our Vega 56 hybrid card to benchmark HBCC in A/B fashion, testing in memory-constrained scenarios to determine efficacy in real gaming workloads.
Wolfenstein II: The New Colossus is launching this Friday, and Bethesda have now published the final minimum and recommended specs. Bethesda is touting some PC-focused features like uncapped framerates (as we saw in the Destiny 2 beta, this can also mean “capped above 144”), choice of aspect ratio (4:3, 16:9, 16:10, or 21:9 ultrawide), an FOV slider (70-120), and 4K support.
The New Colossus will use the Vulkan API, following in the footsteps of the notoriously well-optimized DOOM reboot. In our DOOM testing more than a year ago, AMD’s RX 480 benefitted strongly from using Vulkan rather than OpenGL, as did NVIDIA’s 1080 to a lesser degree. Vega is specifically mentioned in this release, and Bethesda claims that with Vulkan they’ve been able to “utilize the power of AMD's Vega graphics chips in ways that were not possible before.” We’ll be publishing GPU tests as soon as possible.
From Bethesda’s site:
Hardware news for the last week includes discussion on an inadvertent NZXT H700i case unveil (with “machine learning,” apparently), Ryzen/Vega APU, Vega partner card availability, and Coffee Lake availability.
Minor news items include the AMD AGESA 188.8.131.52 update to support Raven Ridge & Pinnacle Ridge, Noctua’s Chromax fans, and some VR news – like Oculus dropping its prices – and the Pimax 8K VR configuration.

Following-up our tear-down of the ASUS ROG Strix Vega 64 graphics card, Buildzoid of Actually Hardcore Overclocking now visits the PCB for an in-depth VRM & PCB analysis. The big question was whether ASUS could reasonably outdo AMD's reference design, which is shockingly good for a card with such a bad cooler. "Reasonably," in this sentence, means "within reasonable cost" -- there's not much price-to-performance headroom with Vega, so any custom cards will have to keep MSRP as low as possible while still iterating on the cooler.
The PCB & VRM analysis is below, but we're still on hold for performance testing. As of right now, we are waiting on ASUS to finalize its VBIOS for best compatibility with AMD's drivers. It seems that there is some more discussion between AIB partners and AMD for this generation, which is introducing a bit of latency on launches. For now, here's the PCB analysis -- timestamps are on the left-side of the video:
We’ve already sent off the information contained in this video to Buildzoid, who has produced a PCB & VRM analysis of the ROG Strix Vega 64 by ASUS. That content will go live within the next few days, and will talk about whether the Strix card manages to outmatch AMD’s already-excellent reference PCB design for Vega. Stay tuned for that.
In the meantime, the below is a discussion of the cooling solution and disassembly process for the ASUS ROG Strix Vega 64 card. For cooling, ASUS is using a similar triple-fan solution that we highly praised in its 1080 Ti Strix model (remarkable for its noise-normalized cooling performance), along with similar heatsink layout.
