    Phoronix: Intel's New Clarkdale IGP On Linux Not So Pleasant

    Last week we shared that Intel Core i3 Linux benchmarks were being worked on at Phoronix with an Intel Core i3 530 "Clarkdale" processor that we had purchased. This recently released Intel Core i3 processor features an integrated graphics processor on the CPU itself...

    Phoronix where writing articles IS the bug report :-$

      Could you guys try to just kill X with ctrl+alt+bcksp instead of rebooting? I'm curious to see what'll happen. You'll need to enable the combo first (at least in Ubuntu).

        P55 motherboard ?
        is not H55 required to use the IGP ?
        or I am messed up with all this new Intel socket/chipset.

          Typo, it's H55. will fix when I get back to my office.

            I'm very interested about i530 performance on Linux as I'm thinking to buy one.
            Tests about performance and also power consumptions would be very welcome.

              GPU hung is not Clarkdale problem, it seems all intel chips affected on 2009Q4. Bug for 965 was recently fixed in kernel, however there's still a bug for gen3 hardware (915-945 chipsets), here it is: http://bugs.freedesktop.org/show_bug.cgi?id=25475

                as i was reading the article i had a strange feeling it was a hardware issue......

                  As somebody already said, this is a driver issue that affects not only Clarkdale. My laptop has an Intel X3100 GPU (using the i915 driver) and I have these same horrid X lockups randomly when closing the lid or suspending, or maybe just sitting idle for a long time (and setting the screen to go blank after some time).

                  I can still SSH into the laptop, and what I see is the /usr/bin/X process eating a whole core. As for the laptop itself, sysrq+reisub is the only thing that physically works.

                  Hope it gets fixed soon, because it is indeed disastrous. I tried the git versions for the intel driver and libdrm, to no avail. So right now I'm stuck with a laptop whose lid can't be closed or which can't go into suspend mode because it's like playing russian roulette.

                    Awww... This is very much like the Wireless screwup Intel's bunch had back about 3 years back. Not good. Guess I'll avoid the front of the source tree for my i945 based devices and hang back a bit on the i3 purchase I was planning on for end of next month.

                      Is this a viable alternative to GT220 + VDPAU for video decode?
                      If not what does it lack in comparison to GT220 + VDPAU?
                      I'm hoping I can mostly get away with it, if not I can always add a GT220.

                      Thanks.

                        jalyst: there's no real usable video decoding acceleration support for intel video adapters yet. libva has some very experimental code for just MPEG format video, but that's all.

                        Having said that, I'd think any Core i* CPU would be more than powerful enough to handle video playback up to 1080P on its own with no real need for assistance from the graphics card. My 'not exactly a speed demon' Intel(R) Pentium(R) Dual CPU E2180 @ 2.00GHz can handle 1080P on a single core quite handily. You only really need hardware-assisted video decoding if you're trying to play some ludicrous quad HD resolution, trying to play video while doing something else very CPU-intensive at the same time, trying to play a lot of video streams together, or using a really weak CPU like an Atom.

                          The thing is, it's also temporarily to be my MythBE & NAS...
                          So there will be other CPU intensive things going on like flagging, transcoding etc.

                          So I was hoping there'd be some freakin hw VA with intel IGP's by now!
                          Sheesh... I guess I have to end up getting a GT220 ?

                            If what AdamW says is right, you'd still have a whole core available. I think that should be plenty enough for a NAS/Mythbackend. Just give them a low priority so they wont interfere (especially when transcoding) and I think you should be fine.

                              Yeah there may well be enough grunt, I'll just have to dive in and see.
                              Any thoughts on what specific makes/models to get for the various parts?

                              Thanks!
