Do I have a second or sixth generation GPU?

  • According to this wiki page here my "Intel(R) Core(TM) i5-2320 CPU @ 3.00GHz" should have a sixth generation GPU however when I ran the 'lspci' it command it says it's a second generation GPU. Can someone explain to me why so? I'm starting to doubt whether I installed the driver correctly.

     

    Here's some info about my system:

    • OpenGL shading language version string: 1.30 Does this mean I only have opengl 1.30 supported on my GPU?
    • OpenGL core profile shading language version string: 3.30 Does this mean I only have opengl 3.30 supported on my GPU?

    This is so weird the first line match the description of the second generation while the second line match the description of the sixth generation in the wiki page.

     

    The wiki page link I was talking about:

     

    Distro: Ubuntu 15.10

     

    Thanks.

  • Hi - three things to note:

    - AIUI there is more than one thing that gets called 'generation' here, so that's probably not a worry.

    - The 2015-Q3 01.org release didn't update the kernel, so you'd be using the same i915 driver
    whether or not it was installed correctly (so again, nothing to worry about here)

    - The text string identifying the GPU comes from the PCI ID database, and is based on the
    PCI IDs (lspci -vnn will show you these) - which is very unlikely to be broken, and wouldn't
    be affected by the i915 driver anyway.
    The PCI ID has two parts, the vendor (8086 for intel) and the device id - taken together, those
    are what you actually want to look up to identify your GPU (but again, that won't alter no matter
    which drivers you install).
