New for Mid-2012: “Enduro 5.5” Enhancements

When AMD created the Enduro brand, they were really almost where we wanted them. They had dynamic switching with support for most of the latest games and applications, and when it worked properly it would be difficult to tell if you were using an NVIDIA or an AMD dGPU. The problem was when things didn’t work and you had to go into the drivers, and there were several problems. OpenGL support was totally out, many of the latest games were also missing default profiles (and sometimes wouldn’t let you properly specify the correct GPU), the UI was obtrusive and sometimes hard to use (particularly for power users), and the drivers were dictated by the laptop manufacturers and were usually months old at launch and never updated.

While the UI seems like a minor thing to fix—I would have thought one or two months to improve the UI would have been sufficient—at least prior to the forthcoming update it remained largely unchanged. The lack of AMD-provided driver updates was really the major issue, because everything else could potentially be fixed with new drivers and you would never know. The other areas like OpenGL/OpenCL and support for various games/applications should improve over time as well, provided you can get drivers. That brings us to the upcoming Enduro release, scheduled to come out sometime this month or next. Officially it’s still just Enduro, but to help differentiate between the previous Enduro release and the upcoming release we’ll sometimes refer to the new version as “Enduro 5.5”.

The biggest news with the latest iteration of Enduro is that AMD is planning to make universal reference drivers available for all the Enduro laptops. It’s not clear precisely what that means, but potentially any laptop with Dynamic Switchable Graphics or later (e.g. PX4.0 and later) would be supported by AMD’s “reference” drivers. That’s huge, and if AMD can deliver it will assuage most of our concerns with their hardware/software.  Hopefully none of the OEMs get bent out of shape or refuse to allow support, which is a problem we've seen in the past. We should see the first public release in the next month or two, and then another release somewhere in the November/December timeframe.

Besides the availability of driver updates, the UI also receives a much needed overhaul, providing both regular and power users all the options they’re likely to need as far as control of graphics switching is concerned. Open up the switchable graphics options and the top section remains largely the same, but the bottom now allows you to see all application profiles (or just the profiles for detected applications). There’s also a quick search option that works both on executable name and application/game name (e.g. HL2.exe or Half-Life 2 will both find the profile for Half-Life 2). From either list (recently used apps up top, or all apps at the bottom), you can set the GPU profile.

Where previously there were two settings (three if you count “Not Assigned”), there are now three options. As before, “Power saving” sets an application to run on the integrated graphics while “High performance” sets an application to run on the discrete GPU. The new third option is “Based on power source”, which does precisely what you’d expect: plug the laptop in and the apps with this setting will run on the discrete GPU; switch to battery power and they’ll run on the integrated graphics. For many users, everything could default to “Based on power source” and they would be happy, but certainly there will be times where you’re running on battery power but still want to use the dGPU and the drivers give you that option. Should things get squirrelly, you can also reset applications individually or globally to their default settings. It’s worth noting that the power state aware setting is something that NVIDIA currently does not implement, requiring manual intervention if you wish to override your normal settings—though how often people are using apps that require the dGPU while on battery power is something we could debate.

Besides the individual application profiles, AMD is also adding a new area to their drivers: Switchable Graphics Global Settings. This is something you could sort of get before with some laptops, but previously it involved changing from Dynamic Switchable Graphics to manual switching (i.e. switching based on power source) and then forcing the laptop into High Performance or Power Saving mode if you wanted to be low power while plugged in or high power while unplugged. That was clunky and at least in the case of the Sony VAIO C we tested it caused flickering similar to the old switchable graphics, with the dGPU drivers getting unloaded and iGPU drivers getting loaded (or vice versa), with some work behind the scenes copying context from one GPU to the other. It worked but it wasn’t elegant; perhaps more importantly, Microsoft doesn’t want anyone doing this with Windows 8 and thus new laptops won’t be able to get a Windows 8 sticker if they use this method of switching (which basically means no new laptops will do this). To make up for the loss of this functionality (which some people still prefer), AMD has added a new global settings section.

Unlike the individual application profiles, the global settings gives you four options each for Battery and Plugged In. The top two options are similar in most cases and will generally run most applications on the iGPU, and the same goes for the bottom two modes where you’ll run most apps on the dGPU. The difference is that “Force Power Saving GPU” will run all applications (regardless of what the custom profile says) on the iGPU, essentially disabling the dGPU completely. “Optimize Power Savings” in contrast will run all unknown or “Based on power source” applications on the iGPU while respecting the application profiles where they exist. “Optimize Performance” is sort of the reverse of that, running all “Based on power source” applications on the dGPU while leaving unknown applications on the iGPU. Finally, the “Maximize Performance” option runs all unknown and “Based on power source” applications on the dGPU—but applications specifically set to use the iGPU will continue to do so.

The reason for that last discrepancy (e.g. why you can’t simply run everything on the dGPU and forget about the iGPU) is that certain tools have to run on the iGPU. Intel’s drivers are one example—loading those up on the dGPU would cause problems. Intel’s WiDi is the only other I could find on my particular Clevo notebook. We were told that some of the laptop utilities like an overlay showing percentage of brightness, volume, etc. may also need to run on the iGPU. Besides the few applications that have to run on the iGPU, any applications that are set to Power Saving will continue to use the iGPU—and this makes sense as there are a lot of applications that can be set to run on iGPU/dGPU that have no need of higher performance GPU options (several anti-virus utilities come to mind, where they're starting to create a 3D context for their UI). The net result is that other than a few specific applications where the profile will exist and be locked to the iGPU, with no option to change to dGPU, everything else that uses higher function graphics can be customized to run on a specific GPU, but if you set something to iGPU presumably you want it to always run there—otherwise you would use the “Based on power source” setting.

A full set of screenshots from all the driver screens is available in the gallery below if you’re interested.

One final topic worth discussing is Windows 8. Certainly there are owners of existing laptops with switchable graphics that are wondering if they can upgrade to Windows 8 and what will happen. We’ll have to see how this actually plays out, but it sounds like the earlier versions of PowerXpress (3.0 and earlier) will probably get support with one driver bundled with Windows 8, and that may be it—but there’s always the possibility for the laptop OEMs to release their own updates, or for AMD to roll out additional drivers for older laptops. The potential for PowerXpress 4.0 and later laptops to get regular driver updates (for Windows Vista/7/8) is there, but until we actually start seeing public driver releases AMD hasn’t fully committed to supporting all of those laptops.

    Enduro is not working ok on any Windows. You get much poorer performance on EM-series Clevos with 7970m than with laptops that have the option to turn off Enduro (Alienware for example). At its current state, Enduro is not working properly and it is making gaming experience worse to those who are stuck with it.

    Follow the issue on Notebook Review's Sager/Clevo forums, that has many threads concerning the Enduro issue:

    There is also a Facebook page that has been created to spread the news about the malfunctioning Enduro technology:

    I own a Clevo P170EM and have long hoped for a solution to Enduro issues that would finally fix my currently crippled AMD 7970M.

    I almost wish I hadn't read those links!

    I was happy with gaming performance under Windows 7, in that it ran everything I threw at it quite happily. Knowing now that it should be even faster will annoy me now. Ah well...

    This is the whole point of the article, guys: Enduro is basically not working all that well in the current form and the UI is terrible, but the preview drivers that should be out either this month or next should finally rectify the situation. Last month I would have said anyone buying an Enduro laptop was going to be sorry; now, at least, there's hope. If AMD delivers on their driver updates -- and really, they have to or their mobile GPUs are something no proper technology reviewer could recommend. Reply

    Why recommend something or even give hope without any guarantee? This is just hearsay from you. As a consumer and someone who already spent $500 on a 7970M, the only thing I've heard from AMD is, a tweet, investigating the issue. Investigating? We know what the issue is, the driver for Enduro is broken! And they have known about it since it's inception, but never said anything, it wasn't until we started creating threads on every forum with a section for AMD drivers they tweeted that one small statement.

    Great they said something to you, but they still haven't said anything to us. And you still don't have drivers, preview of it to prove that this new update will even work!

    They're saying something via us, if that helps. They're saying, "We're finally going to start updating the drivers." There were no promises of Enduro drive updates prior to this point, so this is a big step. As for the drivers being poor on release, well, that's hardly a shock for a brand new hardware architecture -- all the more reason to not buy anything without the guarantee of driver updates.

    I'm sorry people purchased Enduro laptops and got burned. I have specifically recommended against doing so in the past. Now I'm saying that AMD is working to correct the problem. Is it corrected now? No. Will it be corrected soon? Maybe. Would I purchase or recommend an HD 7970M laptop right now? Definitely not (unless it doesn't have Enduro).

    I would wait until at least the official public driver release, and probably one more release after that. By then 7970M is ready to be replaced by 7990M or something faster, but I suspect 7970M will be near the top of AMD's mobile GPU stack for at least another nine months. If they want us to recommend it, they need to fix the drivers.

    This is a class action suite in the making. AMD has obtained a huge amount money for product that does not work, and has allowed 75% or more of the product's life cycle to elapse without addressing anything.

    AMD's next driver update is their last chance. If they do not fix it then I will be dumping AMD for NVIDIA period. I also have no problem joining a class action attack on that company. After years of buying AMD I will not just switch to NVIDIA, but I will become an avid enemy combatant.

    I want a fraction of the money paid for the product to be refunded in compensation for this fiasco. If the company thinks its OK to attack us by forcing forums to delete posts, then I say we go on the offensive and attack them back in return, and see how they like it.

    When they have lost a few hundred million dollars in damages, then maybe they will think twice about ever attacking their high paying customers ever gain. Respect us or expect to be attacked.

    This is a bloody warning to AMD. Yes it is a threat. Fix it or die. Corporate arrogance can be punished in ways they have not even begun to think about yet.

    I hope you only mean "corporate death", this really doesnt justify personal harm...
    dont doubt that with or without FIX this issue is costing AMD a big market share, and an even bigger public opinion drop.
    I can even foresee some public TV report on this wich will further sink AMD.
    All this could happen if AMD doesnt sweat the hell fixing this and making people happy again..

    Did I not use the term corporate arrogance? Did I not mention class action suite? What part of that implies personal harm. Mere loss of market share might not be enough for me to address this corporate attack against their highest paying customers. Let them explain to a judge why such an attack was a requisite element towards the fix. Reply

    Once some1 starts the class action - Im on it...

    I agree wholeheartedly with you on this. AMD released an incomplete product line that FAILED to do what it was SUPPOSED to do in it's advertising and marketing of the 7000 series GCN GPUs.
    Unlike Nvidia, AMD has chosen to be very slow in responding to it's customers' requests for driver updates and fixes to it's Enduro mess that it created. Not only slow, but downright rude, to say the least, because it is by it's silence been unresponsive to creating a workable solution for it's customers.
    Both AMD and Sager told me last month that "there is not problem" with the 7970m GPU.
    Nothing wrong with it? Are they kidding?
    I believe this is mainly due to it's lack of care and concern for it's customer base.
    We all bought 7970's and we are all greatly disappointed by what we got and are seeing in our games, and most of us feel that we should take action against AMD in some form or another.
    My action is, I will pay the $800 dollars for the switchover to the Nvidia 680M at my earliest chance- even though I cannot afford it this year, and then I will wash my hands of AMD once and for all. This is how it will hurt AMD- in the wallet, with it's current customer base going elsewhere from now on to it's primary competitor.

    Not to be a "Doubting Thomas" Jarred, but I am pretty much guaranteeing you that AMD won't have this Enduro mess fixed before the end of the year, if not at all.
    I have made this prediction for this year, and I also feel that AMD will just ignore us with more placation and vague promises long enough, so that once their new 8000 series comes out in the Spring of 2013, they will hope that we owners of the 7970M will simply forget about it, and not care anymore.
    I cannot wait for vague ambiguity and rhetoric from them, so I will save my pennies, dimes, and nickles, and spend it on a new 680M from Nvidia. At least I know that THEY care about their customers, unlike AMD which doesn't.
