back to article Nvidia unveils Pascal, its next-gen GPU with hella-fast interconnects and 3D packaging

Nvidia has announced its next-generation GPU, and with it a new interconnect it dubs NVLink that it says will increase the bandwidth among GPUs – and also CPUs, should a processor designer implement it – over that of PCIe by five to twelve times. Nvidia NVLink block diagram String a bunch of GPUs together with NVLink, and …

    But...

    ... will it run Crysis?

    Can I write in Pascal for Pascal?

    Or would that cause an infinite loop of headdesk?

      No, but you can write fortran in any language.

    Heat?

    Don't graphics cards already have enough of a problem with heat? So won't stacking chips just make waste heat harder as there's less surface area? Or are they going to implement some kind of inter-layer heat extraction?

    TSV

    Didn't nVidia have a bit of a problem with through-vias a while ago? Presumably they've got past those issues now. My memories of the bump thing's a bit hazy, anyone else remember details?

      Re: TSV

      Got to wonder what the yields & MTBF (at package level) are going to be like with zillions of TSVs hooking up a bunch of hot dies.

      Best of luck to them. :)

    Volta

    Wasn't the codename Volta the last time they were talking about it?

    Interesting news

    Memory bandwidth (also between CPU and GPU) is a major bottleneck, and designing algorithms to minimize data traffic over these buses is sometimes very difficult. Higher bandwidth should make designing algorithms for these machines less of a hassle.

    randomly connected...

    I did a presentation a few years back on the "commodity version of Anton" (Anton is MD pecial purpose hardware.

    I have a slide which compares the PCIx vs Hypertransport characterisics, and why D.E.Shaw built their own.

    This would seem to be a natural evolution and the reinvention of the Video bus...

    5 to 12x the PCIe bandwidth

    Humongous strides are still being made in the computing space. This is another stepping stone towards more and more computing power available to individual users. I can hardly wait to see this become a reality.

    I wonder what kind of eye-candy future game developers will throw in to make their plotless games look even better. Maybe some kind of mix between Battlefield 6 and Minecraft ? Truly deformable terrain and structures without any scripting ? Bodies and rubble that stay for the duration of the round ? Blood spurting out of severed arteries ?

    Who knows, we might even get a game with an actual plot ?

    As IBM predicted long ago...

    3D packaging, LOTS of interconnects, then a lot of heat to dissipate.

    Here we are finally at the 'Hairy, smoking Golf-ball'.
