AMD's Path to Polaris

With the benefit of hindsight, I think in reflection that the 28nm generation started out better for AMD than it ended. The first Graphics Core Next card, Radeon HD 7970, had the advantage of launching more than a quarter before NVIDIA’s competing Kepler cards. And while AMD trailed in power efficiency from the start, at least for a time there they could compete for the top spot in the market with products such as the Radeon HD 7970 GHz Edition, before NVIDIA rolled out their largest Kepler GPUs.

However I think where things really went off of the rails for AMD was mid-cycle, in 2014, when NVIDIA unveiled the Maxwell architecture. Kepler was good, but Maxwell was great; NVIDIA further improved their architectural and energy efficiency (at times immensely so), and this put AMD on the back foot for the rest of the generation. AMD had performant parts from the bottom R7 360 right up to the top Fury X, but they were never in a position to catch Maxwell’s efficiency, a quality that proved to resonate with both reviewers and gamers.

The lessons of the 28nm generation were not lost on AMD. Graphics Core Next was a solid architecture and opened the door to AMD in a number of ways, but the Radeon brand does not exist in a vacuum, and it needs to compete with the more successful NVIDIA. At the same time AMD is nothing if not scrappy, and they can surprise us when we least expect it. But sometimes the only way to learn is the hard way, and for AMD I think the latter half of the 28nm generation was for the Radeon Technologies Group learning the hard way.

So what lessons did AMD learn for Polaris? First and foremost, power efficiency matters. It matters quite a lot in fact. Every vendor – be it AMD, Intel, or NVIDIA – will play up their strongest attributes. But power efficiency caught on with consumers, more so than any other “feature” in the 28nm generation. Though its importance in the desktop market is forum argument fodder to this day, power efficiency and overall performance are two sides of the same coin. There are practical limits for how much power can be dissipated in different card form factors, so the greater the efficiency, the greater the performance at a specific form factor. This aspect is even more important in the notebook space, where GPUs are at the mercy of limited cooling and there is a hard ceiling on heat dissipation.

As a result a significant amount of the work that has gone into Polaris has been into improving power efficiency. To be blunt, AMD has to be able to better compete with NVIDIA here, but AMD’s position is more nuanced than simply beating NVIDIA. AMD largely missed the boat on notebooks in the last generation, and they don’t want to repeat their mistakes. At the same time, starting now with an energy efficient architecture means that when they scale up and scale out with bigger and faster chips, they have a solid base to work from, and ultimately, more chances to achieve better performance.

The other lesson AMD learned for Polaris is that market share matters. This is not an end-user problem – AMD’s market share doesn’t change the performance or value of their cards – but we can’t talk about what led to Polaris without addressing it. AMD’s share of the consumer GPU market is about as low as it ever has been; this translates not only into weaker sales, but it undermines AMD’s position as a whole. Consumers are more likely to buy what’s safe, and OEMs aren’t much different, never mind the psychological aspects of the bandwagon effect.

Consequently, with Polaris AMD made the decision to start with the mainstream market and then work up from there, a significant departure from the traditional top-down GPU rollouts. This means developing chips like Polaris 10 and 11 first, targeting mainstream desktops and laptops, and letting the larger enthusiast class GPUs follow. The potential payoff for AMD here is that this is the opposite of what NVIDIA has done, and that means AMD gets to go after the high volume mainstream market first while NVIDIA builds down. Should everything go according to plan, then this gives AMD the opportunity to grow out their market share, and ultimately shore up their business.

As we dive into Polaris, its abilities, and its performance, it’s these two lessons we’ll see crop up time and time again, as these were some of the guiding lessons in Polaris’s design. AMD has taken the lessons of the 28nm generation to heart and have crafted a plan to move forward with the FinFET generation, charting a different, and hopefully more successful path.

Though with this talk of energy efficiency and mainstream GPUs, let’s be clear here: this isn’t AMD’s small die strategy reborn. AMD has already announced their Vega architecture, which will follow up on the work done by Polaris. Though not explicitly stated by AMD, it has been strongly hinted at that these are the higher performance chips that in past generations we’d see AMD launch with first, offering performance features such as HBM2. AMD will have to live with the fact that for the near future they have no shot at the performance crown – and the halo effect that comes with it – but with any luck, it will put AMD in a better position to strike at the high-end market once Vega’s time does come.

    No Virtual Reality benchmarks? This doesn't sound like AnandTech. That's the main reason I am interested in gpu's nowadays. What a disappointment...

    As you can read in the headline, this was a PREVIEW.

    The VR benchmarking situation is currently poor. I'll have something for the full review, but we don't have any good VR benchmarks like we do standard displays. VR Mark and VRScore should be released soon.

    Any MXGP2 players here?
    What are your thoughts about RX 480 8GB playing MXGP2 at 1440p@60fps?
    Recommended GPUs are GTX 970 and R9 390. But this video shows a GTX 970 in-game already at 100% at 1080p with maxed out settings.
    I'm assembling an X99 based PC. i7-6800K, 32GB 3200MHz DDR4.

    You're "into graphics", yet instead of going for a "mid-end CPU/mid-end GPU" combo, you would rather go for "high-end CPU/Low-end GPU"? If e.g., you went instead with an i5/1070, you would probably be able to down-sample from 3K to 1440p and still have a locked 60FPS.

    He is trying to get "followers" for his youtube channel. Don't even click the link or you will drive up his view count, which will only encourage him to spam comments with more links to his video.

    No worries, I never click on random forum links, unless it is porn, lol. Just kidding.

    Are the reference RX 480 cards going up to other reference cards in this comparison?
    Or were some or all of their competitors equipped with aftermarket coolers and factory overclock?
    What was compared here?
  • sparrowkhx - Thursday, June 30, 2016 - link

    AMD hype again, 2 RX 480s probably beat a single 1070 while consuming twice the power and ultimately being a similar cost... They definitely aren't going to beat a 1080 and I'm even more glad that I purchased an EVGA 1070 FTW for 429.

    Additionally, I haven't been on Anandtech since the 1080 preview, seriously what is the deal with all these previews and missing reviews? I'm more interested in reading the reviews than random articles and other places are actually doing full reviews not previews.
