Tom's Hardware Verdict
Asus did a great job designing a sharp-looking Radeon RX Vega 64 card that performs better than AMD's reference implementation. We would have liked to see the company put a thermal pad between its PCB and backplate, though, to counter high board temperatures under load, along with using slightly higher fan speeds. Regardless, the prices of all Radeon RX Vega 64 models remain a little too high for a recommendation at this time.
Pros
- +
Excellent 1440p performance
- +
Good build quality
- +
Aesthetically pleasing design
Cons
- -
Price is still too high
- -
Temperatures rise in closed cases
- -
Fan speed should be a little higher
- -
Missing a thermal pad between PCB and backplate

Features & Specifications
AMD's Radeon RX Vega 64 is as fast or faster than a GeForce GTX 1080 in our gaming benchmarks. That much is well-established fact. But up until recently, the flagship Vega card was priced well beyond Nvidia's alternative, making it easy for us to recommend the GeForce instead. Now that Vega 64 is becoming more affordable, though, it's getting harder to choose between the two high-end options.
The Asus ROG Strix Radeon RX Vega 64 8GB OC Edition we're reviewing today does cost $70 more than the least expensive Vega 64 model (and $100 more than the cheapest GTX 1080). However, it does add RGB lighting, a big heat sink, quiet fans, a second HDMI port for VR headsets, and high-quality components. In the end, those extras aren't enough to justify such a big mark-up, particularly when the Radeon desperately needs a price break to secure a competitive advantage.

Unboxing, Look, & Feel
Weighing in at 1286 grams, this card lands between Gigabyte's much lighter Radeon RX Vega 64 Gaming OC 8G and the aforementioned behemoth from Sapphire. Asus goes big on the physical dimensions, too. Its ROG Strix Radeon RX Vega 64 8GB OC Edition measures 30.2cm long, 12.7cm tall, and 4.5cm deep.
Three 90mm fans are mounted in 92mm openings. With their special shape, a total of 11 rotor blades per fan provide airflow and turbulence, rather than just static pressure. This should prove beneficial to Asus' thermal performance.
The backplate is embossed with an illuminated ROG logo. That plate doesn't help with cooling at all; it's primarily meant to look good and give the card some rigidity.
Plan for an extra 5mm of clearance (at least) behind the ROG Strix Radeon RX Vega 64 8GB OC Edition. This may cause problems on some motherboards, particularly if the heat sink/backplate intrude on an occupied expansion slot or large CPU cooler.
As we can see from the bottom, Asus employs vertically-oriented fins. At the expense of occupying a third slot with its 2.5-slot design, the company does open up more room for airflow.
The dark plastic shroud covers part of the top, creating room for a back-lit ROG logo. Toward the back, you'll find a pair of eight-pin power connectors that are rotated by 180 degrees and recessed a bit, sitting flush with the PCB.
In addition to five 6mm heat pipes, the board's closed end reveals two PWM-controlled fan connectors able to accommodate optional case fans, an RGB output, and LED headers.
The rear bracket plays host to five display outputs. A pair of HDMI 2.0 interfaces is ideal for anyone with a VR HMD, while two DisplayPort 1.4 connectors make multi-monitor configurations easy. Dual-link DVI ports aren't as pervasive as they once were, but Asus still gives you one. Since the card's cooling fins face up and down, we're not particularly worried about those five outputs interfering with airflow.
Although Asus' official documentation claims a 1590 MHz boost clock, GPU-Z reports 1630 MHz. That specification is mostly wishful thinking though, given a 295W power limit.

darkchazz "Missing a thermal pad between PCB and backplate"Reply
My Strix GTX 1080 I got in July 2016 also has missing several thermal pads on the GDDR5X modules. Many others reported this issue too and I suppose they still haven't fixed it at the production line. -
Kaziel I just bought one for USD599 on June 6th and waiting for all the parts to arrive. I really hope it'll be okay in an NZXT H500 with the 2x stock fans as exhaust and 2x Noctua NF-A14 as intake.Reply
Do you guys think that my EVGA SuperNova 650 P2 will be able to handle an overclocked R5 2600x and this Asus Strix Vega 64? -
milkod2001 @KAZIELReply
That depends how many other components you also plan to connect: Sound Cards, HDDs, Blue Ray Players, etc, ect but i think it would be OK with 1 SSD and 1 HDD. -
Martell1977 It would have been interesting for Tom's to make the modification of adding the thermal pads and show how much of a difference it would really make. I wonder if ASUS felt it was a acceptable trade off between looks and functionality.Reply -

Still waiting on parts to arrive.

Planning on just letting Ryzen Master auto overclock the 2600x. For the Vega 64 I plan to do the widely suggested undervolt, +50% power, and overclock HBM2. I have used the calculators and they basically say it's fine, but then again I left everything at stock. Not sure what the values are yet for going about overclocking the two parts so unsure what to put in the calculator. -

Price had went down a little but still a complete joke of a price. More power and heat than 1080 , cost more, released later. Sry Amd you better figure out better marketing and sale strategies or do better in the tech side of things preferably both. -
alextheblue Wow there's commenters that still don't have a clue about the impact of mining, which lingers on Vega to this day.Reply -
zodiacfml Where the undervolting benchmarks if it is mentioned that it is better for overclocking and the mentioned poor exhaust vents?Reply
I think the critique for most of the Vega 64s are the large PCBs. It deserves smaller PCBs such as found in the Vega 56s to improve cooling. -

Nice review, but some Far Cry 5 benchmark would've been nice.21047101 said:...
Newegg now has this card for $599, which I think is pretty close to MSRP.
