External Graphics Over PCIe 3.0? Netstor's NA255A, Reviewed
By

We ran these numbers prior to the launch of Crysis 3. So, we take a look back its predecessor, Crysis 2.

At just 1920x1080, we're not using a high-enough resolution to make three Radeon HD 7970s sweat. Thus, a platform-oriented bottleneck keeps the dual- and triple-card configurations generating similar average frame rates. There's one outlier: two Radeon HD 7970s plugged into the TurboBox. Because three cards in the same enclosure perform as we'd expect, that could have been a configuration problem (we went over several of those on page two).

The dual-card issue rights itself at 5760x1080. However, the TurboBox doesn't scale as aggressively when we step it from two to three Radeon HD 7970s. Fortunately, we have a couple of other demanding apps coming up that can either contest or corroborate these findings.

    Now if only we could get external GPUs via Thunderbolt (or it's future iterations) so that laptops wouldn't be forever gimped, we'd be in business!

    This is a nice article. I wonder if Tom's can do a multi-cpu article as well.

    Whooo whoo, if i had the money to burn, i would get this NA255A, remove the PSU bundle, replace it with a Seasonic 1000 Platinum, slap four GTX Titans, add a custom water-cooling loop, connect it to my main PC and have (if it works) three more NA255A's for each of the PCIe for the main PC with a grand total of 16 GTX Titans for massive GPU computation. All for a grand total of $13,800. Massive electric bill, here i come!

    PCIE signals scale poorly to long wires. So it is a technical achievement to have these signals travel over a meter of wire.

    There are some external GPU cases.

    The only issue is that the cheapest is somewhere slightly less than $400.

    Please explain to me how an aluminum box, a micro-PSU, and a Thunderbolt-to-PCIE adapter adds up to even $200...

    EDIT: And when I meant the cheapest, I meant the ones that are only sufficient for a 7750. Want to pair a 7970 with a ultrabook?

    $400-$500 for a slightly longer box with a slightly more capable PSU.

    Good X79 workstation mobo with 7 PCI-e slots, and 4 K20x-s on each of them. That's a TON of computing power, and if you don't want to deal with high-speed networking multiple boxes, that's nice. Of course only if this thing can actuallty work in pairs or more and in some way circumvent the 15 gpu limit in bios memory mapping. Can this thing be turned on with working machine?

    Mac/Apple users either don't care about or don't under price/performance . My guess, they won't care about the price, just that it doesn't come in pretty colors.

    Would have been nice to see some Nvidia hardware thrown in to see how they get on.

    What additional conclusions could be drawn concerning internal vs external throughput?

    Apple users are a select group of users, alot of high school kids and girls use them. Not trying to be funny just an observation. If you buy into the Apple thing you have to do things their way and on their terms. Apple has always been cost prohibitive and too restrictive for me personally.

    My sister's thoughts when buying a 13" Macbook:

    "If it's light, not battery draining, durable, and works, then it's good enough."

    $13,800? Check your math- I think you forgot a few titans.
    4x NA255A @ $2200 = $8800
    16x Titan @ $1000 = $16000
    4x Seasonic 1000 @ $230 = $920
    Total of $25,720 before adding the custom water loops.

    this box should be 200$ max

    the PLX chips are being used in motherboards long ago , and the whole motherboard with PLX chip is 300$ only .. as a matter of fact the PLX chip is 50$ only

    add 50$ for case and power and 50$ for board and cables and 50$ profit

    what 2200$ ?

    I hope Asrock or Asus make such boxs soon for 200$ and with SLI option as well. ...

    who needs a stupid useless Thunderbolt when u can have native external PCIe 16 ?

    next stop add that port to a notebook .. one to one PCI 16 x no PLX chip... and notebooks will be desktops
