    Phoronix: ARM Cortex-A15 Quad-Core Linux ODROID-XU Tests

    When the first ARM Cortex-A15 SoCs started rolling out in devices I found the dual-core A15 performance to be crazy fast for ARM and still find the Cortex-A15 performance to be great for low-power devices. Now, however, there's quad-core Cortex-A15 SoCs and even with the big.LITTLE architecture these four A15 cores can be paired with four A7 cores. In this article are our first benchmark results to share of a Samsung Exynos 5 Octa with a 1.6GHz Cortex-A15 configuration paired with a quad-core Cortex-A7 processor...

    Would be great to see this processor compared to the new Snapdragon S4 800

      Looks like it's noticeably better than Odroid-X2 with quad core Exynos, and it's getting close to Sandy Bridge i5 (my benchmarks: http://openbenchmarking.org/result/1...FO-1305102FO57 ). The only problem is that ARMs GPUs doesn't have as nice drivers as Intel ones (+usually Android oriented and not X.org).

        I still have a hard time understanding the purpose of the big.LITTLE architectures, or other similar platforms such as OMAP5.


        Anyway, I own an odroid-U2 and it's a pretty fantastic platform. I wish there was openGL acceleration (rather than OGL ES) but it being a quad core makes up for the performance hit it takes for having the CPU render everything.

          Odroid already published some PTS benchmarks.

          I wonder how much the benchmarks actually stress the hardware, threaded benchmarks should perform better here. Also it will be interesting to see whether the performance jump is significant when the new Heterogenous Multi Processor chips come out that can utilise all 8 cores at the same time.

            I'm very interested in purchasing an ODROID-XU for running a GNU/Linux server on it and potentially even purchasing one for basic desktop use, but I can't find much information about how the PowerVR SGX performs in X.Org? Would anyone here be able to clear up a few things for me?

            I see mention above that the card supports GL ES.

            Are there any drivers (open or closed) that work on a GNU/Linux stack that allow it to do 3D rendering in X.Org? If so, what kind of performance do you get?
            Where do you obtain drivers? (I had a quick search on the PowerVR site and saw nothing of use)
            Can it render 1080p videos fine, and does it support hardware decode of many formats?

            Are there any other Cortex A15 boards that use a GPU from a company that is a little more supportive of open source, or at least has some in-development drivers even if not driven by the company producing the chip? (e.g. like the lima project).

              Pretty cool results, even seeing the Samsung Chromebook beating out the atom d525 when it's half the threads and (I think) a lower frequency.

              I'm getting the impression that those tests were only for the 4 A15 cores, which is still impressive results.

                Odroid-XU vs Odroid-U2

                I own one of the older Odroid boards, the Odroid-X, which was subsequently superseded by the X2 and now the XU.

                Currently, Odroid sells two boards, the XU and U2. The XU is almost twice the price of the U2, and the U2 is super small in size. Also, the XU uses more power and it's even recommended that you install a fan (included with the board).

                My point being that there are some reasons why people are still buying the U2 rather than the XU, though I'm sure both are great. So what I would really like to see is a comparative benchmark showing the XU vs the U2. It would help me make a decision on which one to get (maybe I'll even get both and use them for different purposes).

                  That's what really has me wary of much of this ARM stuff. Getting non-insane drivers is probably like playing Russian roulette. Then you have the chips from third-rate Chinese companies where you have to pray that you can get kernel compatibility.

                  Somewhat ironically, I'm almost ready to think that NVIDIA will end up being the go-to ARM guy for people who want sane drivers. I don't think they're in any dev boards like these though... except maybe that Kayla thingy.

                    Things are rapidly improving though.

                    Sadly there is no fast SoC with things like SATA, a useful GPU _and_ an existing developer community.

                    Without the latter, you're really nowhere.

                      I am looking forward to the quadcore Kabini cpus from amd with 15W or 25W TDP.

                      A comparsion between this 2 would be great. This thing uses a active cooler so the tdp will be also higher than 5W right? So a comparsion in TDP, Price and Speed would be great. But even if there would amd loose slightly the great opensource drivers would be the desiding factor in favor of amd I think.

                      And it would be great if amd could make this boards in this century buyable. Waiting forever... maybe they produce to much garbage ps4 console socs.

                      Where I see potential for such boards but for that it has to much tdp it seems (active cooler) would be tablets... because there you become from amd it seems only 800 dollar 640x480 resolution Windows 8 garbage tablets.

                        Both Mediatek and Rockchip are making equal octacores (not big.LITTLE), composed of eight A7 cores. IIRC Mediatek's one even had a Mali 400.

                        These would be interesting to compare when they come out. Not as performant as A15 per core, but much lower power too.

                          This not the Snapdragon 800's competitor, though. The 1.8 Ghz Exynos 5420 is, with a more powerful GPU. I'm not sure if the Note 3 international has it and if it's been reviewed yet.

                            I'd like to see these compared to Intel's Bay Trail Atoms in terms of performance and driver stability and features. Been wanting UMPCs to make a comeback. I used to have an OQO slider and a Viliv N5 but they weren't Linux friendly.

                            edit:
                            Oh, this needs a fan. What's the power ratings for this board?

                              So far Bay Trail is barely competing with last year's dual dual core Cortex A15 and ARM GPU's:

                              I've stopped buying Intel's BS a long time ago. Wait until the reviews are out instead of believing Intel a year before the release about how their chips about how their new chips will totally destroy ARM chips. When they come out they tend to only be competitive with chips from a year before, in both CPU, and especially in GPU performance.
