hey everyone i'm steve from gamers nexus donna and today we're talking about the razor blade stealth core that would be the external GPU enclosure accompanying the razor blade of stealth that we looked at previously on the channel if you want to see more about that hit the channel linked down below but before we get to that all this content is brought to you by our powers revolt to a small form-factor gaming PC the core box is actually pretty interesting compared to the other external GPU enclosures and that is primarily because it is a non-proprietary unit so this could actually use for other devices you don't have to use the razor blade stealth laptop with it and that's different from say alienware is you know that came out last year where you had to use the alienware special connector at a proprietary connector in this case it just uses USB type-c to connect the core to the blade stealth and that's a pretty big deal and that you could use type c with other things not just the laptop that raisers making and the other non proprietary connector is of course thunderbolt version 3 which has a 40 gigabit per second throughput and that is what enables us to do the external GPU at speeds that are somewhat reasonable the speed translation there you're stopping down a pcie x 16 gem 3 slot to about pcie x 4 so you lose a bit of the laning because of the 40 gigabits per second cap on thunderbolt 3 but that translates to about a six percent FPS hit in gaming so it's not a huge real-world performance hit on the rear side of the enclosure there's a Gigabit Ethernet port which will obviously take up about a gigabit of your bandwidth there's also for USB 3.0 ports which operate at somewhere around five gigabits per second 4.8 and with four of those had about five you're running 20 gigabits per second with ethernet at one so saturated and all that Foley which is pretty unlikely you'd be running your GPU at a fairly hamstrung speed it would be suboptimal but because the USB 3.0 ports will almost never be operating at fully saturated speeds unless you're driving a bunch of extra drives off of it it's really not that much of a concern because the pcie x 16 at the 40 gigabits per second USB type-c or Thunderbolt 3 protocol will be plenty for most gaming the razor cores also not they worked with Microsoft with Intel with Andy with NVIDIA on the driver support and the main thing here is that you can disconnect the razor core sort of almost hot-swappable style you can just disconnect it through the interface as you would do with an external hard drive and then reconnect it and just kind of go as needed so the reason that was a challenge is because of Optimus with laptops that do the internal I the igp or the internal GPU on the CPU and the dedicated GPU and run them together with the razor core the drivers are loaded as soon as the GPU is connected and once it's disconnected they're unloaded so that's all done on the fly and that was the most difficult part of developing this unit with all the software support to learn more about the razor blade stealth and core check the previous video we did on the channel where we looked at it at the AMD suite at CES 2016 thanks for watching we'll see you all next time you
