Introduction

A couple weeks back, I contacted AMD to let them know I was working on a notebook review—a Clevo P170EM from AVADirect with HD 7970M graphics. Much to my surprise, when I received the notebook I discovered it used AMD’s Dynamic Switchable Graphics, now rebranded as Enduro. It has been just over a year since my last look at the technology, where things were so bad that I felt most users would be better off if they had only discrete AMD GPUs and no switchable graphics—or they could simply buy NVIDIA Optimus enabled laptops. The short story is that my initial experience with the P170EM was largely the same, only the lack of driver updates was even more damning when looking at a notebook sporting such a high-end GPU. What could be done? AMD scheduled a meeting with me to go over the latest updates, and thankfully things aren’t quite so grim as I first thought.

First, let’s get everyone up to speed. Historically speaking, AMD/ATI has been on the forefront of switchable graphics technology. While the first laptop with switchable graphics tested at AnandTech used NVIDIA’s implementation (the ASUS UL80Vt), Radeon-based alternatives also existed in a similar time frame. The main problems with early switchable graphics solutions is that they required extra hardware on the manufacturer side (muxes), increasing cost, and more importantly you were generally locked in to getting graphics driver updates from the laptop OEM. NVIDIA addressed both problems when they launched Optimus in early 2010, and while there were certainly some teething pains the vast majority of users have been pleased with the result. Where did that leave AMD? Simply put: out of most laptops.

Was it because NVIDIA had superior technology, better drivers, or better marketing? I’d say yes to all three, and it has been painful to watch as the number of laptops with discrete GPUs (at least in the US) has largely shifted to being NVIDIA products. Up until now, if you wanted a laptop with a discrete GPU, the ability to switch off that GPU, and you wanted regular driver updates, your only viable option has been NVIDIA equipped laptops. Perhaps that’s why every major OEM (along with most smaller OEMs/ODMs) ships at least some of their laptops with NVIDIA’s Optimus Technology. With laptop sales now outpacing desktop sales, giving up so much ground to their competitor is a serious problem AMD needs to overcome.

I should note that AMD has other products that actually help get around our concerns with Enduro. The Llano and Trinity APUs for example offer integrated GPU that are as fast (faster in some cases) as discrete GPUs. If you’re looking for a good budget laptop that gets excellent battery life and you don’t want to deal with switchable graphics at all, Llano started the trend of providing a decent GPU with acceptable CPU performance and Trinity continues that trend. Even better: driver updates aren’t a problem as there’s only one AMD GPU to contend with. Trinity/Llano didn’t win any awards for pure performance, but in terms of bang for the buck and creating a well-rounded device, the APUs have proven successful. But we’re not going to worry about Trinity/Llano or other APUs; today’s focus is on discrete GPUs and switching between these high-power, high-performance GPUs and low-power, low-performance integrated graphics.

With that out of the way, let’s look at the history of AMD’s switchable graphics as well as where they intend to go in the near future.

Recap: AMD’s PowerXpress, aka Dynamic Switchable Graphics, aka Enduro

    you DO have a point, i agree with you.

    Maybe this aint the best place for this, lets keep this article a source of help and not an open window to complain, just a thougt...

    The good news is that we won't be deleting anything here, I can guarantee that. You might also consider asking NBR and the other places where threads have been deleted exactly why they did so. If a forum kowtows to the manufacturers and deletes negative posts -- especially posts that are full of data showing the problem with a specific set of hardware -- I'm not sure I'd trust the forums any longer. Actions like that are basically saying, "We want advertising money more than we want members." Reply

    Maybe so, but there is a lot that should be said and was not said. Two issues needed to be differentiated - the fix itself, and corporate shenanigans, and the latter needed some attention. I will try to be silent now. Reply

    Excellent points! Well said. Reply

    The problem with this is, I didn't know about the Enduro mess causing low FPS rates and utilization problems until after the 30 day return policy was up.
    I suspect the same thing can and will be said by others as well.

    Since we all had no idea initially that Enduro was causing all this when we bought our Sagers, it was only starting to snowball downhill with more and more reports coming in about this. Then I got to see it firsthand with the games that I played, and that was after the 30 day return period, so by then, I will stuck with it.

    I contact Sager about it, and they told me that there was no problem with the 7970M, so there was nothing I could do about it, short of swapping out my GPU card for the Nvidia, and that, they said, would cost me $800 dollars to do.
    Obviously, Sager was flat our wrong about it, and that makes things even worse for all of us.

    I find it curious AnandTech's reviewer wasn't more shocked that the 580M performed better than the 7970M in over half the games. If you look at the specs AMD posted, the 7970M is about 2X more powerful than the 580M. The in game results are just incredible, I really hope AnandTech edits the article to be more outraged that a machine that costs $1,500 today performs less than a $1200 machine in half the games. The current 675M is a rebadge of the 580M and costs signifitcantly less. What if the 7970 desktop performed less than last years 580 in over half the games? But I forgot, this is mobile, and us mobile users don't matter.

    On the popular NBR forum, threads are being closed and deleted because AMD has issued legal threats to some OEM/Brands who have been nice enough to try and gather feedback to help us owners. NBR was asked by said OEM, and NBR complied because said OEM, Sager, have been a great supporter of the forum and had great relations. They did this as a favor, so NBR is not to blame, nor is Sager.

    A post from NBR that clarifies that it was in fact AMD that requested the threads to be closed/deleted.

    Please check Rage3D. On Rage3D we've had an advocate on our behalf and AMD continues to ignore his inquiries and it's been 2 months with no results since AMD claimed they were investigating the issue. Clearly for AMD, mobile users are second class and do not deserve the performance they paid for, even though the mobile counterpart to desktop part is nearly 2X in price. The 7970M is a $500 piece of hardware and yet we just get spit in our face.

    I know on NBR, Rage3D and Guru3D, 7970M users are furious. And on this review, I get the sense, it's meh, AMD is working on it. No big deal attitude.

    Sure the article title and the objective of the thread is biased, but I think overtime it will clearly show that mobile gamers right now, in their opinion between the two flagship titans, Nvidia 680 at $300 more is a better value, since it works.

    You are absolutely right about this. For us sorry 7970m owners, it simply amounts to the old saying: "Penny wise, pound foolish", because since Sager said that if I wanted to swap out my 7970m for the FAR BETTER Nvidia 680m, it would cost me a total of $800.
    Gee, what would I rather do- spend an extra $300 now, or $800 later?

    Hmmm....wait...let me think...

    The choice is an easy one for everyone involved- spend the extra $300 for a far better GPU now, or spend A LOT more money later when you realize that what you just bought and supposedly "saved" $300 dollars on with an AMD, isn't what you bargained for.

    Either way you look at it, spending an extra $300 to save $500 makes a lot more sense.

    Take it from a guy who owns a Clevo P170EM with a 7970M built by Malibal. To say I am very disappointed in AMD's negligence in terms of providing support or even just a public statement or some kind of assurance for their non-functional technology, is a huge understatement. The thread we started in the AMD forums was locked because some AMD fanboys who don't own a GPU with Enduro problems (with no understanding of the issues whatsoever) started flaming us. The thread Sager started over at NBR was locked and deleted. The last time @CatalystCreator acknowledged the Enduro issues on Twitter was almost a month ago and hasn't mentioned it since. I've asked a few AMD reps on Twitter about Enduro problems that plague the 7900 series and one of them directed me somewhere else but then sent me a malicious link privately. (I have proof in my email.)

    But look no further than the NBR forums (NotebookReview.com) to see what my fellow 7970M owners have to say. Keep in mind that most of these guys are hardcore AMD bandwagon, fanboys. When the Enduro issues first surfaced, these guys stuck with AMD like they owed AMD something. Now read what their honest opinion is after they've seen and experienced the Enduro issues. It's not in our imagination, but we are getting brushed off while AMD sweeps this one under the rug. After all, why focus your money into fixing this problem or providing a recall when you can use that money and put it into R & D for the next generation of GPUs to rip off even more people?

    I'm not here to hate on a product I paid over $600 for, obviously. If I could defend it and be proud of it, like I hoped I would, I would really much rather do that. But I can't. I'm just a very disappointed customer who put faith and money into AMD's product and in turn was left hanging high to dry.

    My advice to those looking into building a high end custom laptop? Do you research. Don't go to these biased reviews sponsored by AMD. Go to the forums where real owners own the actual product. Watch out videos, logs, tests, etc. THAT'S where you can find FACTS.

    (I reckon my comment will be deleted for whatever fishy reasons, but at least I tried.)
