Sapphire Gearbox 500 eGFX Enclosure (Thunderbolt 3) with Pulse RX 6600 XT Bundle $699 + Delivery (Was $1099) @ Scorptec

240

Was looking around for Thunderbolt 3 eGPU enclosures for my GPD Win Max 2 and found this gem. This is a pack with both the eGPU enclosure (Which itself is around $500) bundled with a Sapphire Pulse 8GB RX6600 XT (@$400-450).

From the Manufacturer page:
The GearBox 500 PULSE RX 6600 XT Thunderbolt™ 3 eGFX Solution features the low-noise and high performant 8GB PULSE RX 6600 XT graphics card. Powered by the latest AMD RDNA™ 2 architecture, this PULSE RX 6600 XT Thunderbolt™ 3 eGFX Solution delivers a noteworthy boost to professional and gaming applications and also features a lightning quick 40Gbps Thunderbolt™ 3 connecting interface that handles various types of data and is capable of charging a Thunderbolt™ 3 configured device.

Can offload the RX6600XT and basically get a eGPU case for cheap.

    my man, the 6600 xt is regularly $350-$400 now.

      Still good value when you put it against the enclosure

      I mean if you need the enclosure too…. Have a quick look and there is no local gpu enclosure under 400$ I believe

      Hasn't been sub $400 for a while. Been on the lookout for one…

      You are comparing Apples with Androids.

    • Not to pile on, but what do you imagine they will be plugging that card into?

        Not my problem, the comment was made in response to OP's original claim that 6600xts were $650, implying that it was only ~$50-$100 extra for the enclosure. It has been revised since.

    This is a great eGPU for anyone still using a 2019 Intel MacBook Pro 16".

      I am using that MBP. Could you please suggest the best eGPU and enclosure combination I can use? Would really appreciate

        The best GPU you can use is a 6900 XT. You need the XTX model rather than the XTXH model (you have to Google the exact PN to find which one you’ll get). You can change some settings to make the XTXH model come up in Mac OS as an XTX and I don’t think you’ll have any issues. I personally bought a 6900 XT ASUS TUF OC as I knew it would work.

        Then just buy a Razer Core X or similar eGPU enclosure.

        I think a Razer Core X w/ Radeon RX 6900 XT would be the best combo but also pricey.
        Apple support docs has some good info on this topic.

        With the transition to Apple silicone this wouldn't be a good investment though. But should be able get a few years of use anyway and offload the GPU later.

        I have been using a 2019 MBP 16 with a Razer eGPU Enclosure and started with an ASUS Strix RX580. While it was fine, the older fans are noisey and the idle temps are basically clipping the fanstop on and off all the time, which is an issue. The only way to solve this in MacOS is VBIOS flash and have the fans on all the time.

        I have since tried 6800XT and a 6600XT in there and I can tell you now, the 6600XT is the aboslute goods. I mean if you're encoding videos or playing hardcore games the 6800xt is better, but ….. there' a few things you need to consider.

        I want a silent setup, 120hz OSX Desktop with VRR. The 6600XT with desktop duties in MacOS there's basically no fans/noise (sometimes with teams or Google Meet on you would get a spinup but its near silent). Thunderbolt 3 / PCIEx4 - overhead massively gimps your GPU anyway. It's the same limitation no matter what GPU you have, but having a 6800xt in there feels like a complete waste.

        The 6600XT Nitro+ that I have in there rarely turns the fan on, playing some games you still get like 90% of the performance of the card (sometimes you notice the assets loading into VRAM) but you really aren't leaving too much on the table.

        In terms of 6600XT Fan start / stop is the only noise you need to consider. I believe the MSI Gaming X, Colorful Red Devil and XFX 3 Fan variants are basically zero noise. Once the fans on the Nitro+ are spinning you can't hear it.

        Ultimately, it's upto you as to what you want.

        For an awesome OSX desktop with some gaming, an eGPU and a 6600XT all day long.

        If you wanna game primarily, just forget about Mac OS and build a midrange Windows desktop. I have tried it all including Hackintosh (and it works well) but there's alot of energy/frustration to get to that point.

        My only concern with this deal/eGPU (the card inside is fine) would be the 40mm fan on the PSU. Check some YT reviews to see if it's loud?

        One final note, as much as I want the 'single cable life' using USB and Network ports on the eGPU's typically takes bandwidth from the Thunderbolt GPU - just don't use them.

        • Also, only 60W PD from this eGPU which isn't enough for a MBP16 for instance - just keep that in mind.

        • Great inputs. Thanks for that.

          When Intel MBP was mentioned, I thought we are implicitly referring to BootCamp Windows.

          My games run fine (not on max settings which I would like) on Windows. Want to use a eGPU setup (in Windows 11) which

          • allows for max settings at 4-6K (have a 5k and another 6k monitor)
          • future proof
          • can go up to 2-3k if the setup is future proof
          • @thegreatermamba: If using Windows on a MBP16, the combination of the onboard 5500M/5600M causes MASSIVE problems with an AMD eGPU (and AMD Pro drivers, not Adrenalin) - no matter which AMD GPU I used. Error 12 in Windows is the bane of the MBP16. Laptops without a dGPU don't have this problem, but they're pretty average.

            The only way I could get a eGPU with Windows on a MBP16 to work consistenly (and without running a version of windows 2 years old) was to use an NVIDIA GPU - which then wouldn't work in MacOS. NVIDIA in Windows was basically flawless - but again, the performance is gimped.

            Again, remember Thunderbolt 3 is 4x lanes PCIE v3 - 40GBits then take off TB overheads. The GPU's really want/expect 16 lanes which is 4x the bandwidth you're providing with an eGPU enclosure. Then there's also issues with TB3 actually didn't guarantee 40gbit/s (TB4 does), and some TB3 laptops are 20gbit/s etc.

            It's a real shame that eGPU's are kind of ignored in terms of progression and software evolution. It's a great concept, but no-one wants to invest time into it other than end users/tinkerers - and it's an expensive hobby.

            Again, I would highly recommend a Wintel small form factor hidden under the desk for gaming. :)
