  • Laptop recommendation wanted

    I was looking for recommendations on laptops with the following features:

    1. Decent OpenGL support. Particularly 3.x
    2. OpenCL support
    3. Decent battery life (4+ hours) under Linux

    As for pricing, the less the better. I am looking at some of the AMD Fusion E-350/Radeon 6310 powered notebooks as they seem to offer all the above at a great price but if there are any others that you can think of, that will be great.

    Isn't Intel i3 and i5 better choices than AMD's offerings still? What's the update on laptop hardware these days?

    I think that there's no compatibility with any Nvidia GPU chip combined with Intel i3 - i5 laptops still?

    OP, I think an Intel gpu is probably the best bet for compatibility and the open source offerings with the Intel gpu should give some OpenGL and OpenCL support or development towards it?

    Others in the know are better to say, though. I'm interested to know, myself.

      OpenCL support pretty much rules out all the open drivers, including Intel. And in extension every laptop with switchable graphics, as those can only be used with the open drivers.
      Most modern laptops with nvidia-graphics are Optimus and thus not supported on linux, so that's not an option either.
      So what you want is something with a low-power AMD-GPU, so your Fusion choice definitely makes the most sense.

        Core i5 with GT Nvidia 540M.

        Not sandy bridge, but still an i5.

          Thanks for the clarifications!

            Definitely something AMD. Fusion would be a nice choice. OpenGL 4.1, OpenCL, the works.

              Optimus. You most likely won't be able to use the nVidia-GPU at all. It's just going to sit there and draw power without doing anything.

                Hmm, weird. I read the reviews.. it doesn't say it's an optimus, but it is.

                I wonder how that would work with linux... if you load the nvidia driver would it just use nvidia all the time and ignore the integrated? Since Optimus doesn't work on Linux (right?)

                I have an i7 laptop with nvidia 425m and I love it. It works great with linux and I've been using it to play oilrush on high settings at an avg of 25fps.

                What's the deal with the Definitely something AMD? Why?

                  Because of the way Optimus works (the Intel graphic is connected with the display at all times, the nVidia card renders it's image in the memory of the intel card), you can't even just use the nVidia card and ignore the integrated. You're stuck with the Intel IGP.
                  That's why Optimus really is not an option. And there aren't many not-Optimus notebooks anymore (though evidently there apparently are some as you appear to have one). A not-Optimus notebook with nVidia graphic might be an option, but I doubt there's one which manages to do 4+h battery lifetime.

                    AMD Fusion E-350/Radeon 6310 = super slow and AMD problems in Linux.

                    One positive: good battery life.

                      Optimus is not available in linux and will not be available.
                      AMD video support is absent, except to some extent by catalyst(which itself is not best option on laptop)
                      Get newest intel hardware.

                      If you need power laptop, go with nvidia...
                      But without optimus.

                        Catalyst is okayish. There is really nothing wrong with it, it just isn't the greatest. The AMD graphics are still way faster than the Intel HD graphics. That being said Intel HD graphics are much better than previous generations.

                          Big size, small hardware support frame, bad video acceleration, periodical breakage, not good with wine, some rather not ideally implemented opengl4 extensions(read about it, dont want to tryout even if I have amd card), OpenCL behind nvidia. Now AMD hires people for OpenCL so OpenCL/Stream situation may improve.

                          Yes, they are catching up, but the biggest problem is small hardware support frame, where you will have to buy new card or use opensource drivers that receive way less attention and will have many features missing forever. Id still go with amd driver if there is opensource driver working and absence of video acceleration is not a deal.

                            I haven't ever had a problem with a newer laptop and Catalyst. Pretty much all hardware that Catalyst supports will work in a laptop. The whole wine thing, I honestly have NEVER run into. As for the OpenGL 4.1 extensions, I haven't had a problem with them. It will run Unigine like a champ with tesselation. Honestly, I haven't even found a real linux application that uses OpenCL so I really can't comment. Also, nVidia won't support Optimus. For AMD graphics on Intel iX series laptops support is in the works for switching between them, or so the rumors say.

                              Depending on your preference of course. But I guess it's better to read some reviews before you decide on that matter. As much as I want to actually suggest a particular brand I think you will have an eye for that if you know exactly what you really want and of course your budget.
