macOS 10.13.4 Enables Support for External GPU (engadget.com)

With the latest release of macOS High Sierra, Apple has officially delivered on a couple of items in the works since WWDC 2017 last June. macOS 10.13.4 brings the external GPU (eGPU) support that lets developers, VR users gamers and anyone else in need of some extra oomph to plug in a more powerful graphics card via Thunderbolt 3. From a report: While that may not make every underpowered laptop VR ready, it certainly makes staying macOS-only more palatable for some power users. Another notable addition is Business Chat in Messages for users in the US. Twitter, Facebook, WhatsApp and others have tweaked their services to enable customer service linkups and now Apple has its version available on the desktop. With it, you can interact with business representatives or even make purchases. Other tweaks include waiting for the user to select login fields before autofilling password information in Safari, a smoke cloud wallpaper that had previously been restricted to the iMac Pro and a Safari shortcut for jumping to the rightmost tab by pressing Command-9.

  1. What lag does it have? by Anonymous Coward · · Score: 0

    An external GPU can certainly have the power to do things ... But what delay will it introduce?

    Because the delay of many input devices, plus the horrible lag of most displays, plus the game's lag itself is already too much as it is to feel right, compared to e.g. my gold standard (cabled PS2 or 1000Hz mouse, CRT at 85Hz and Quake 3 Arena ProMode).

    How much difference, in SI units, does the fact of it being external make?
    Surely the protocol must differ, to compensate for a long and flexible cable with an imperfect connector.

      Some benchmarks for alienware's graphics amplifier and Razor's spotted bandwidth limitations with a hit on performance of about 30% or so (compared to an internal PCIe gpu), but not delays. Now, if you're still well better off with that performance hit (intel hd!) or not it's a different matter.

      I've had an akitio node for the past 6 months or so, paired with an asus 501vw laptop and GTX 970; and the external GPU has worked fantastically.

      There's a bit of a performance hit as parent said, but 30% seems a bit high; I think it's largely dependent on your screen resolution and what FPS you're hitting.

      At this point if you're shopping for a new gaming computer; it's probably in your interest cost/benefit wise to go with a desktop. BUT, if you have either a spare video card lying around and want a second gaming computer; or if you only want a single computer and need it to be portable -- eGPU's are good compromise.

      For Apple in particular, this could be a very good idea.

      A big part of Apple's marketing is that "creative people use macs". Certainly a large proportion of artists, musicians, developers and designers I know do, but we are getting increasingly frustrated at the lack of performance in Apple's "pro" offerings. Crucially, most MBPs sold only ever get used for light office work; people buy them because they have the cachet of being the tool "creatives" use, and so if they buy them they will be a creative too... right? So if 90% of their "pro" machines are used by people who don't actually need any performance, it's hardly surprising that Apple have been pushing the features that sector cares about (fancy flashing lights, thinness and portability) over the features actual creatives need (speed, capacity, ports).

      I for one am frequently bottlenecked by this top-of-the-line MBP, but I'm sure that many more people are hoping the 2019 model is even thinner and lighter. If Apple don't follow 90% of their market (pseudo-creative hipsters) they are idiots, but if they continue to cut features that actual creatives need, they'll lose a key USP.

      Yes, I could just use a desktop workstation when I need to, but nobody likes switching back and forth between multiple computers; it's bad for workflows, it means administering and configuring everything twice, and having a robust procedure for syncing data. A standard interface for hot-pluggable external graphics and CPU would mean being able to have a light, low-power machine for carrying around, and be able to plug it in to any workstation rig (home, office, meeting room, a client's site etc) and get down to work.

      If Apple get this right, they go from "coasting on momentum" to "innovative first mover" in the performance workstation space.

  11. Macs should be somewhat faster by SuperKendall · · Score: 1

    From the PCWorld article:

    The proprietary cable itself carries data at x4 PCIe Gen 3 data rates. Thatâ(TM)s about 4GB/s. For comparison, a standard GPU connection on a desktop is a full x16 Gen 3 connection, which carries about 16GB/s.

    The Thunderbolt 3 connection is good for 40 Gbps, or 5GB/s. The iMac Pro has four USB-C ports that have two separate buses, so theoretically you could even do 10GB/s, I'm not sure how Apple's eGPU box is wired up.

    That's of course just the speed from the computer to the card, if you have.a display attached to the card then that does not factor into resolution or monitors supported.

      One addendum to everything you said (which is correct): just because it has 25% as many PCIe channels doesn't mean the performance is 25% what it could have been. In practice, a GTX 1080 will still perform at about 70-75% of its capability when connected via x4 instead of x16. There won't necessarily be any delays, but the raw performance will be less than what the card is capable of.

      One other minor note: Apple isn't selling an Apple-branded eGPU box at this time. It's possible they might when the new Mac Pro debuts later this year or next, since they've talked about going to a more modular design and this change would seem to lay that groundwork, but whether they will or won't remains to be seen.

    A large amount of cooling for games goes into cooling the GPU. So if you are running anything graphic intensive with an eGPU, the system will have a much easier time keeping the processor cool even if you are running it really heavily.

    Also more modern Macs have really good cooling design. The iMac Pro hardly ever spins up fans to where you can hear them, only during gaming - and even then not at max.
