    Raja Talks Vega Pricing, Perf/$, Perf/Watt & Untapped Hardware Features

    Raja reiterated AMD’s previous statements regarding supply and reinforced the company’s commitment to deliver as many Vegas as possible as soon as possible to retailers worldwide. He went on to briefly touch on all the media buzz that’s been surrounding Vega’s pricing issues. Many pointed the finger at AMD, accusing it of marking Vega chips up over the advertised MSRP, something that Raja emphatically refuted. Saying that doing that would only help the competition.

    All students of economy know that pricing is subject to the forces of supply and demand, and as supply continues to be limited we have little doubt that the drama and blame game – miners gobbling up supply, retailers accusing suppliers of raising prices to take advantage and vice versa – surrounding the current situation will go on until supply normalizes.

    Due to the nature of how Twitter arranges tweets in reverse-chronological order I’d recommend reading the tweets starting from the bottom.

    The Balancing Act Of Power And Performance
    Raja went on to discuss Vega’s performance per dollar and performance per watt. According to Koduri, Vega 10 has the largest performance per watt dynamic range of any GPU. In other words Vega’s design allows it to be setup in a way that makes it extremely frugal and power efficient if desired and the extreme opposite is also true if performance is the only concern, at the expensive of power. Also, according to Raja, Vega has the widest feasible operational power range in either direction of any GPU in existence.

    Raja explains that due to this fact the RTG team had a very flexible range of perf/watt and perf/$ that they can optimize Vega around. They wanted to strike a balance that would please as many users as possible and their research indicated that perf/$ was more important than perf/watt for a larger portion of users than perf/watt. Although in an effort to please everyone, the team implemented three separate operational power modes for Vega. A Power Saver mode, a Balanced mode and a Turbo mode.

    Turbo mode tells the GPU to run as fast as it absolutely can and to hell with power consumption. The Power Saver mode on the other hand makes sure that the GPU sticks to a very efficient power/frequency curve whilst not sacrificing much performance. Balanced mode, as the name suggests, is a middle ground between the two.

    Vega’s power efficiency can only be exposed and truly appreciated in power saver mode. In the RX Vega 64’s case this mode can save up to 120 watts of power, cutting effective power consumption by over 35%, whilst only slashing performance by roughly 4%.

    When pushed for further detail Raja stated that a lot of the growth in transistors/power in Vega was related to the implementation of Infinity Fabric and Vega’s plethora of new features, some of which require further software enablement to be fully leveraged.

    infinity fabric and many of the new features some of which still need software enablement explain most of the delta

    — Raja Koduri (@GFXChipTweeter) August 30, 2017

    AMD Radeon fans have long coined the term “fine wine” to describe the process by which AMD’s GCN based Radeon GPUs mature overtime and often significantly surpass their NVIDIA counterparts in performance. The HD 7950 Boost for example was originally a GTX 660 Ti competitor back when it came out in 2012, but over time we’ve seen it not only outperform the more expensive GTX 670 but also the GTX 680 and even the GTX 770 in many gaming titles as time went by.

    Raja’s comments regarding Vega’s well of untapped hardware potential brings that term to mind, although he emphatically denies that he was referring to “fine wine” in his tweet. So, only time will tell whether the same story will be true for Vega, .

    For me only 1440p, so PUBG is UE4 -> means what it means ;)
    Vega need some UE love tooooo :rolleyes:

    Fortunately for me my UE510 4K monitor does fullscreen 1440p as well, and it's pretty sharp too. Not exactly sure if it's upscaled, or the monitor is running in a 1440p mode. This option makes running my 390 with some titles very doable.

    Onna: once you go 2160p, 1440p seems a bit lol. :)

    My Vega 64 and EKWB will arrive on Tuesday.

    Shall report my results when I get the system back together.

    Sidenote Overclockers UK has the sapphire Vega 64s in stock for 505 USD.

    Will be very interested to see how you get on. I don't think I have seen anyone post there results with some aftermarket cooling.

    Let us know how that worked out. I tried the exact same thing yesterday and my Vega wouldn't boot with the waterblock on. I removed it and fitted the stock cooler again and now it works.
    Is there some kind of restriction due to disconnecting the fan and led pins? It is the only thing I can think of that is different.

    I wonder if something is causing a short.

    I'm using EK FC and backplate, no troubles what so ever here. In fact, this card has been absolutely amazing so far. Not one crash or black screen in weeks.

    Just broke 8k graphics score benching Timespy as well which I'm pretty pleased with. http://www.3dmark.com/spy/2321085

    Grats,
    BTW i can Buy one now :D
    My Shop have Sapphire in-stock, but for 620€ with 2 Games :p
    I will pass (no Hot Head Today) and wait for Good aftermarket XFX Black OC !
