Disappointingly Inconvenient 9/22/2019 12:54:59 PM

Pros: - Graphics performance
- Numerous display combinations, daisy chained DP with DVI and HDMI
- Handles multiple simultaneous 4k CAD and games contexts well

The performance of the card is fantastic and functions as expected. There are only a few games I needed to step down from 3840x2160 in order to obtain a consistent 45+ fps.

It has no problem keeping up when I have multiple 4k CAD style applications and VM contexts with dedicated allocations of graphics memory displayed simultaneously across multiple displays.

Cons: - Mode switching

The card has major issues when switching display modes.

When switching between resolutions, the card will halt the signal to the display for a relatively long period of time. This period of time is long enough for many display port monitors to enter sleep mode. And unlike DVI/VGA displays, DP devices can be considered "disconnected" when in standby or off. The result of this, for example, if I open a full screen game, the card will stop sending a signal during the resolution change, the monitor will enter standby, which will be interpreted by the card as disconnected, which it or directx will decide to cease the new mode, which results in switching back to the previous mode, allowing the monitor to turn back on with the game either not in focus or without a graphics context. In comparison to my previous card, I was able to start a full screen non-native resolution game within ~300ms. The best workaround is to get the game to use a windowed mode rather than full screen, which is often difficult without first opening the game.

I don't let my computer sleep, but I do let my monitors enter standby when I'm not using them. When waking the card/monitors up, the card behaves oddly.
One scenario is when my DVI display, which has old slow CFL lighting, will show an image before my DP displays, which are all LED backlit and are capable of displaying an image from standby within 500ms. This will often result in waiting 5-30sec before seeing an image on my main displays. What is even more strange, is when this begins to happen, I can swap the DP ports being used on the card, and the DP displays wake up near instant once again, for a period of time.
Another scenario is when my DVI display shows static, seemingly random RGB colors that are constantly changing. And when this occurs, putting my monitors back in standby, and wake them back up resolves the issue.This and numerous other diagnostic approaches confirms this is solely the card.
Another scenario is when I put my monitors into standby, sometimes the DP monitors will all stay on, while displaying a black screen, and the DVI display will turn off correctly. When waking the displays in this state, the DP monitors will enter standby, while the DVI monitor will wake up. Again, rotating the DP connections on the card will often temporarily "fix" this.

Overall Review: I have been a long time ATI, now AMD, consumer, and this is the first high-end card that I cannot recommend. I do not know if the problems are caused by ASUS or AMD in this case, as this is the first ASUS AMD card i have used, and I do not have a different brand vega to test.

For reference, the card I upgraded from was the XFX 290X, which to this day results in flawless, near instant, full-screen mode switching with the same monitor combination I have setup for the vega.

I'm not the type of person to accuse a product of flaws until I have thoroughly eliminated other possibilities. I have devoted a lot of time to diagnosing and attempting to resolve the problems encountered with this card, and have determined that the card is the culprit. I don't know if a driver can can fix it or if there is a hardware limitation, but I've tried numerous driver versions, different displays, and different computers.

Why not AMD? 9/26/2018 5:31:26 PM

Pros: Awesome card. Quality is evident. Fan/cooler design is brilliant. The LED design and control is great. Multiple HDMI outs, if you want to VR you can do so without messing around with cables. The quality of AMD's graphics display is underrated. Benchmark geeks love to do color coded bar graphs showing results of super intensive testing. Real world use: the Vega 64 is at least a match if not outright superior to the nvidea 1080, and nips at the heels of a 1080TI at worst.

Cons: Not a super big deal, but this card is MASSIVE. it is very heavy. i put this into my Ryzen/ ASRock Taichi build, my Taichi mobo has reinforced slots specifically for the purpose of dealing with these modern gigantic heavy GPU cards. If you do not have "steel slots" then make sure you get the screws in nice and snug!
Also a "sort of" con, word is you need to tweek the voltage(in provided software so no biggie) to achieve advertised clock speeds. I mean if you are intent on benchmarking this card and insist on maximum performance, you will need to do this. See other reviews for relevant comments. Out of the box it is more then capable, so don't read to much into that.

Overall Review: At a price(still cringe worthy, but they all are) 2/3 if not less compared to nvidea's 1080 series cards, this card performs on par if not better. I was skeptical at first, but the proof is in the pudding, this card is performing brilliantly for me. Don't get sucked into the OC'ing benchmarker's hype charts. The Vega 64 is a great GPU.

Simply a Masterpiece - Highly Recommended. 8/16/2018 11:26:00 PM

Pros: + Best Looking GPU Cooler on the Market. ASUS continues to impress with their STRIX Design AMD and NVIDIA GPUs.
+ Very Good Temperatures for Both Gaming and Mining. Card Never Exceeds 65' C on the Core and 75' on the Memory, even when Overclocked.
+ Gaming Performance is Impressive Across the Board. Perfect for 1080p High-Refresh Rate Gamers, 1440p Casual Gamers, or even the 4K Enthusiast Crowd.
+ Don't Forget about dat RGB Lighting. Makes this card look unbelievably sexy.

Cons: - Overclocking Performance is Meh, but requires work to achieve. Your Results will vary, but I only got as far as 1550 Mhz on the Core, and 1150 on the Memory, while keeping the voltage at about 1050 mV.
- Fans can be Noisy if you set an Aggressive Profile to achieve stable temps. I have a 60% Fan Speed Profile (About 2300 RPM) and the Fans can be heard.

Overall Review: Running this in my Main System, aka Project Foundation, which uses the following:
CPU: AMD Ryzen 7 1700 (OC to 4.0 Ghz. @ 1.45V)
Motherboard: MSI B350 PC MATE (BIOS Version AE.0)
Memory: 16 GB (2 x 8 GB) Crucial Ballistix Elite DDR4-2666
Storage: 240 GB Corsair Force LE SATA SSD
Storage: 1TB WD Black 2.5" 7200 RPM HDD
Storage: 1TB WD Blue 3.5" 7200 RPM HDD
GPU: ASUS ROG STRIX RX VEGA 64 (The GPU You Are Checking Out Now)
Wi-fi: Gigabyte GC-WB867D-I AC Wi-fi Adapter
Case: Phanteks Eclipse P300 ATX Case
PSU: Thermaltake Smart 650W 80+ Bronze Power Supply
OS: Windows 10 Education 64-Bit
Monitor: Alienware AW2518HF (1080p, 240 hz, 1ms, AMD Freesync)

This Graphics Card is Everything I was Expecting. A Masterpiece of a Graphics Card for all the things I want to do. Gaming? No Problem. Virtual Coin Mining? Absolutely. Video Rendering and Streaming? Depends on the Application, but Yes. With the RX Vega Graphics Cards from AMD, it may not beat NVIDIA's Offerings, but with Reasonable Expectations, it can do just about anything you want to do and thensome. It all depends on your needs.

Hope this review helps you all. You can find me on YouTube @ SoundFX09.

I really am enjoying this monster. 8/5/2018 4:18:46 AM

Pros: -It has serious power
-It's AMD
-See other comments

Cons: -See other comments

Overall Review: The best video card I have ever owned. I am using an LG 34-inch Freesync ultrawide monitor @ 2560x1080. It runs everything I throw at it flawlessly. I have it paired with a Ryzen 7 1700 @ stock settings on an MSI Tomahawk B350 and 16 GB of DDR 4 3000 @ 3000 MHz.
The key things to know in order to enjoy this card from AMD & Asus:
1. You really need a good Power Supply. 650W minimum, 750W or better preferred. I personally went with an EVGA G3 850W. No problems.
2. You absolutely can run it out of the box as is and get great gaming performance without tweaking it. However, you MUST have a quality case with EXCELLENT air flow. It will generate heat, although it does not get nearly as loud as the blower style models.
3. If you simply go into AMD settings and enter Global Wattman, you can easily undervolt most of these Vega cards. Manually set the P6 and P7 state voltage from 1150 & 1200 to 1100 & 1100 respectively. Then, set the power limit from 0 to 50%. This will allow the card to give you the highest clock performance at the lowest temperature, as the card will boost clocks on its own due to the lower voltage and temps. It will get no hotter than 75C under gaming load with fans at 2400 rpm. It will stay at roughly 1590-1610 boost clock depending on your case ventilation. This trick works with both Vega 56 & 64. Vega 56 will run even cooler but roughly 12-15% slower on average. You're welcome.

Last piece to my AMD puzzle!! 7/21/2018 8:18:23 PM

Pros: Its fast for what it is and plays everything and looking good while doing it with a nice RGB Backplate so hope you have a glass case!!
AMD drivers are getting better so the card is getting better.
Best cooling solution you can ask for with 3 fans.
Can make it reach or surpass the GTX 1080.

Cons: No cons for Performance, But should have been 1080Ti better!!!
Overpriced still by $90 Compared to MSRP Thanks to the aftermath of the miners.
Heat- Gets hot but it is a GPU, Can be overcome by extra case fans so it can hit higher clocks.
Watt usage is up there can hit 400 watts if not undervolted.
Heavy- so tighten the PCI bracket screws tightly.
Big- Make sure it will fit, My case has this PCI bracket protector for the PCI Screws, Couldn't put it back on.
Personal sidenote- Bank account still feeling that $600 Burn... LOL

Overall Review: Undervolt- You have to Undervolt to keep it cool so that it can clock higher, Have mine on -100 volts so its at 1.100v and the watt usage is around 280 to 300 underload.
Performance- Its fast and can play everything at decent FPS over 60 FPS. Have mine limited to 130 FPS to keep it from generating unnecessary heat. Its hitting 1700MHz and Mem @980MHz but its HBM so dont need to overclock this much.
Uses Aura to control RBG i like the software, Some have problems so i hear!!
The most expensive and best card i have ever bought but the performance i get doesnt make me regret it!!!

Great 1440p performance! 7/13/2018 10:40:51 AM

Pros: + Great performance
+ Runs cool and quiet
+ Finally priced decently (Maybe a little high still)
+ Well built and solid!

Cons: - Limited overclock potential
- Needs to be undervolted to see true potential
- Power hungry compared to competition

Overall Review: I have been running a Asus ROG Strix GTX 1080 for over a year. Great card. Overclocked to 2025/11000 for everyday use.
However I have two freesync displays that it cannot fully take advantage of, so after seeing a sale on this Asus ROG Strix Vega 64 on another one of NewEgg's stores ($474 after discount code and cash back) I decided to bite.

First off, it looks pretty much exactly like the 1080 version. Super hefty and well constructed. Once powered up, the lighting is the same as well. Looks good with default red lights, if you are into that sort of thing.

Once powered up, I ran some tests at default settings. Testing 3dMark Timespy , Scored 7489 at stock settings. Peak clock rate was 1545 with an average around 1520 sipping 220W peak. Then I overclocked using Wattman, setting state 6/7 to 1632/1692 clocks with 1.0v, HBM to 1050mhz and power limit to 50%. 68C temp target. With those settings, I scored 8270 with peak clocks hitting 1642 and averaging around 1620. Power usage jumped to 250-260W. So about 10% better performance for 20% more power usage. With the temp target setting at 68C, fan speed is generally around 50% which is slightly audible, but still quiet.

The above OC score compares favorably to my OC'd 1080, which scored 8290 in timespy. In real games, frame rate performance between the two is so similar, unless you are measuring it would be impossible to tell the difference. However once you throw in Freesync, the Vega becomes very obvious how much smoother it is. More so at 4k than my 1440p 144hz monitor. At 4k the 1080 would sometimes feel laggy and stutter while the Vega with Freesync active would be very smooth and felt much more responsive.

So in the end, which do I prefer? Both are excellent cards and perform great. If you do not have a Freesync or Gsync monitor it really is a toss up and as long as prices are similar go with whatever you prefer. But if you have a Freesync enabled monitor or plan to get one, the Vega 64 gets the nod in my opinion even if prices are slightly higher (maybe up to 10% as freesync is worth it). Asus has done a good job here with a well made card that runs cool and performs well and does not require a OC. If you are looking for a Vega card, it is a great choice!

She's a Great Ol Chunky Beast 7/3/2018 5:57:05 PM

Pros: -Excellent beefy cooling solution for AMD's flagship, that giant ol heatsink does it wonders.

- Temps never got above 66° under full load at 2560x1080p on any games I ran with a good fan curve. If you set it up right, it should not have to be too audible.

- Was expecting much higher power draw, but was pleasantly suprised at how much it actually needs when you UNDERVOLT IT. (THIS IS CRUCIAL WHEN OVERCLOCKING, DO NOT FORGET TO DO THIS!!!)

-Max Power Draw was on average 255 watts when undervolted and OC'd and under full load.

- Was able to hit a constant 1576 mhz on the GPU Core with 1050 mV, and 1100 mhz on the Memory Clock.

- Excellent Timespy score of 7212 on my OC. Firestrike yielded a graphics score of ~24,500-24,600 on average.

-Overall excellent FPS in my games. Titan Fall 2 reported 130+ FPS on all ultra settings @2560x1080p. Im sure you should be able to get at least 60 FPS 4k if you tweak your settings.

-Dope RGB led's matched up with my build really well. (Case is Corsair 460x in white)

-Great DX 12 support from what I am seeing. AMD's drivers seem to be optimized for DX 12 and have a bit more trouble on DX 11 titles.

-Very impressed overall with this card. Its a great performer AND IF UNDERVOLTED, you will get great results, especially with the aforementioned cooler.

Cons: - I am going to be completely honest and I have only found 2 cons while using this chunky boi.

- 1.) AMD Wattman will take some getting used to. It has a few minor bugs, at least the version I was running at, but they were very minor and I couldn't notice them most of the time. I tried using Asus GPU Tweak II, but its extremely buggy and is really a bad tool. I tried OC'ing with Afterburner as thats what I normally used, but it is pretty buggy too with Vega and won't give you as much control as Wattman does. I highly recommend using Wattman, it will give you a much easier time!!

-2.) Another minor gripe I had was that before undervolting my card, HBM2 would get very hot. This can lead to a few crashed, but DONT WORRY. If you undervolt, you will drastically decrease temperatures and you will stabilize your card!!

-Overall, these cons really dont outweigh the performance and temps that you can achieve. I got this card for a good deal and it honestly does not dissapoint.

Overall Review: As a final note, I'm going to emphasize this for like the 70th time: UNDERVOLT YOUR CARD. Many, and when I say many, I mean M A N Y people have failed to do this in reviews and I see people in comment sections saying its a faliure of a card. If you know what your are doing, you will see results.

When OC'ing, it will take some learning and time. You must be patient and do your research. As mentioned above, Wattman may confuse you at first, it takes time. I spent a good 2 days tweaking my voltages and clocks to find a good OC. Be prepared for crashes, and some possible frustration, as with any type of overclock! If you are patient, you will unlock the full potential of this card!

I recommend using Fire Strike, Time Spy, and a mixture of Unigen benchmarks and games to ensure a stable OC.

This is a great card and I highly recommend it!
