3 BIG Z13 eGPU Problems! Thunderbolt or XG Mobile?


There’s absolutely no chance I can recommend a Thunderbolt eGPU configuration with the ASUS Flow Z13. I’ve had 3 significant problems with it, this is what you need to recognize! This ROG Flow Z13 video gaming tablet has Nvidia’s RTX 3050 Ti inside, yet it’s additionally obtained one of the most prospective GPU expansion out of any kind of device until now. Not only does the Z13 have Thunderbolt 4 assistance, so we can affix a desktop graphics card over Thunderbolt, yet ASUS additionally offers their XG Mobile. Basically any kind of laptop with a Type-C thunderbolt 4 port can utilize the desktop computer GPU enclosure, while ASUS’s XG Mobile presently just collaborates with their gadgets that have this custom port. Now this includes their Z13, X13 and X16. Currently a Thunderbolt external graphics enclosure similar to this one undoubtedly offers you much more upgradeability because you can mount whatever desktop computer card you like. I’ve obtained Nvidia’s original RTX 3080 in this one. The XG Mobile I have actually got makes use of a laptop RTX 3080 GPU, so it’s much less effective contrasted to the desktop computer 3080 in terms of the raw specifications. The mobile GPU in the XG Mobile has less CUDA cores and a reduced power limit contrasted to the desktop variation, but it’s also much smaller and also a lot more mobile because of this, though at the expense of much less upgradeability as you would certainly need to change the entire XG Mobile device if you intend to change the GPU.

Interestingly the XG Mobile 3080 has even more VRAM than the desktop computer card, however the desktop card is using quicker GDDR6X memory. One of the largest drawbacks of a Thunderbolt eGPU setup is that it’s restricted to 4 lanes of PCIe Gen 3 over Thunderbolt, and also relying on the tool you’re linking it to, that signal might initially need to go by means of a Thunderbolt controller that’s exterior to the processor. Modern Intel styles have actually that integrated in to the CPU though, which does give a performance enhancement. However still, this is the primary reason why a desktop computer graphics card performs worse in a Thunderbolt eGPU room contrasted to just running it in a desktop computer PC. There’s just more above with Thunderbolt. The XG Mobile on the other hand utilizes 8 lanes of PCIe Gen 3, it’s simply a more straight link with more bandwidth. Alright now below are the 3 major troubles that I had while checking a Thunderbolt eGPU with the Z13. The initial significant issue was whenever I linked my Mantiz Saturn Pro II eGPU unit over right here, the Z13 would certainly blue screen within regarding a min. It would certainly simply rest there in a boot loop until I disconnected the room. Currently I had the ability to work around this by making use of DDU to uninstall the Nvidia drivers after that connect the room and after that reinstall the Nvidia motorists, but that’s not specifically something useful you would certainly intend to do whenever you connect your eGPU to Z13. Currently thankfully ASUS were able to duplicate this a couple of months ago or two and they have given that turned out an upgrade that solutions the trouble via the

MyASUS software program. As much as I’m conscious, that problem is repaired. Yet the second issue I had was just as frustrating. When we attach an external GPU by means of Thunderbolt to the Z13, the Windows operating system sees it as a hardware change. It’s obtained a brand-new GPU. Currently with Windows 11, which is set up on the Z13 by default, Microsoft heavily urges if not pressures you to use an on the internet Microsoft account, and also when it does this it makes it possible for Bitlocker security by default for your protection. There’s just one tiny issue. Whenever Bitlocker sees that equipment has been transformed, it fanatics out and also does not allow you boot the device. Essentially after I had that blue display boot loop issue before, I was presented with a Bitlocker screen. This suggests I needed to utilize a separate tool with Internet accessibility to log in to the Microsoft account to get the 48-digit Bitlocker secret. What a smooth procedure! Don’t have a different gadget with Internet connection? I guess you’re not starting up the Z13. My initial workaround for this was to disable Bitlocker, but once more ASUS have actually stated that they’ve fixed this issue in an update. Linking a brand-new gadget via Thunderbolt shouldn’t sign up as an equipment modification that triggers Bitlocker. Ok so that’s terrific, but I’m actually starting to feel like I’m the BETA tester for this product. Specifically when

the 3rd issue still exists in mid-May 2022. The Z13 is billed with 100 watts over Type-C, and it features an ASUS branded 100 watt Type-C battery charger. Now my eGPU room can use 100 watts of Type-C charging over this single Thunderbolt cord, so I should have the ability to connect this one cable in as well as fully power the Z13 right? Wrong. Obviously the Z13 can only get the complete 100 watt charge with that consisted of ASUS Type-C battery charger. I’ve been informed that the reason for this is that the power gets sent directly to the motherboard, which is meant to be extra efficient. Others evidently send the power first via the battery which acts as a little bit of a buffer. So with this style, if a 3rd party battery charger has any kind of spike in power delivery, it can potentially harm the device. To avoid a third party charger perhaps killing the Z13, it is limited to 65 watts with third event battery chargers, which includes the Thunderbolt room. After that the inquiry becomes, is 65 watts of power shipment sufficient to offer you full performance with the Z13? The response appears to be possibly not. If I simply run a CPU work like Cinebench on loophole, CPU plan power seems to limit to a 30 watt TDP in manual setting, while turbo setting is completely grayed out, which takes place when the battery charger isn’t linked. If I instead connect the 100 watt ASUS charger to the bottom Type-C port and leave the eGPU attached to the Thunderbolt port above, the CPU plan power runs higher at 50 watts. Which is likewise the same limit if we do not have actually the eGPU attached. Generally to get the full power restriction with a Thunderbolt unit linked to the Thunderbolt port, we likewise require to connect the ASUS power adapter to the bottom Type-C

port at the same time. Jarrod Technologies, possibly your eGPU simply sucks? ASUS believed that was an opportunity too, and also they claimed that the Z13 functioned fine on 2 different enclosures based on their screening. I did in fact connect to the Mantiz guys that make this GPU unit to see what they assume, and regarding they knew they could not understand why it would certainly be an issue with their room. I spent more than a month waiting for ASUS to supply me with one of their eGPU units that they examined on the Z13 to verify it for myself, yet it simply really did not wind up taking place for whatever factor. At some point I reached out to Razer and also asked if I might borrow the Core X Chroma, as it’s primarily a first-rate Thunderbolt eGPU enclosure as well as a little bit even more of a name brand name contrasted to the Mantiz unit. Sorry friend … Anyway the exact very same thing occurs with the Razer unit. The CPU TDP obtains limited to 30 watts with only the eGPU linked and the ASUS 100 watt battery charger requires to be linked at the exact same time for it to run up to 50 watts. Ok, so simply run the Z13 with two Type-C cables attached, trouble addressed right? Unfortunately not. Although linking both Type-C cable televisions does improve CPU just performance, game efficiency was still all over the location. Allow’s see exactly how 12 different games do at 1080p, 1440p and 4K resolutions. All game testing was

performed with Razer’s Core X Chroma with both Type-C cable televisions connected to the Z13 unless otherwise specified. Allow’s start with Control, yeah it’s an older video game currently, however it is just one of the only video games out of the 12 where points really look typical and also just how I would certainly anticipate, so it’s a great location to start. I’ve tested making use of the Z13’s display at 1080p, and after that with an outside display connected straight to the eGPU, which must execute a little better due to the fact that the signal does not require to get sent out back from the eGPU to the Z13 and processed by the Z13’s GPU. Anyhow at the lower 1080p resolution, the higher transmission capacity from the XG Mobile provides us greater structure rates. At 1440p as well as 4K however, the Thunderbolt eGPU configuration has the ability to reach greater typical FPS, and this is because the desktop 3080 GPU is more powerful and it can obtain to work. That stated, the dips in performance shown by the 1% lows are very reduced with the Thunderbolt setup, possibly due to the lower data transfer, or maybe the CPU power limitation roguishness. Alright currently below’s Red Dead Redemption 2, as well as excuse me, however what the heck is going on here? There’s plainly some sort of traffic jam from the Thunderbolt eGPU arrangement, since it’s just reaching a little over 30 FPS no matter the resolution tested. I examined this game on both the Mantiz Saturn Pro II and Razer Core X Chroma enclosures as well as obtained the exact same results, so this is not a trouble with a certain Thunderbolt enclosure. Somehow the desktop computer graphics card simply isn’t

running appropriately, it’s going for like 50% application with low power levels, yet I can’t function out why. I get the exact same results whether I run the test with one or both Type-C wires connected. I additionally tried a fresh Windows reset, however this didn’t transform anything either. Just for comparison, last year the X13 with the very same desktop computer GPU was reaching 61 FPS in this examination at 4K, so yeah, there’s an unidentified trouble here. View Dogs Myriad was running like garbage on the Thunderbolt eGPU too. I mean, yeah certain if we lowered the settings down a bit or used DLSS it would execute a little bit much better, yet begin, the XG Mobile has an enormous lead at all resolutions. Also the 1% lows from the XG Mobile were much in advance of the ordinary FPS coming out of the Thunderbolt configuration at 1080p and 1440p, an awkward outcome for Thunderbolt. The numbers coming out of Shadow of the Tomb Raider on the other hand look good. The desktop computer GPU has the ability to take the lead at greater resolutions as expected, however this video game demonstrates yet an additional issue I had with the Thunderbolt unit. It had not been even able to pack the video game up on the Z13’s display, it just maintained crashing, as well as that’s why there’s no information for it. Granted I believe lots of people would most likely use an external display on a Thunderbolt arrangement, however regardless, not an excellent look. The XG Mobile is much more portable so it’s a far better alternative if you’re taking it with you to boost pc gaming performance on the go with the Z13’s display. The Witcher 3 is another older game, but is an additional where the game crashed directly away when loading it up on the Thunderbolt

arrangement on the Z13’s screen, so at least 2 different games that are unplayable unless you’re making use of an outside screen. Cyberpunk 2077 looks alright in terms of average FPS, but the 1% lows coming out of the Thunderbolt arrangement are past a joke. The dips in performance as well as stuttering were more apparent compared to the XG Mobile, despite it having a lower powered laptop GPU. Sure the desktop GPU was providing a greater ordinary FPS at 1440p as well as 4K resolutions once more, yet it simply would not be an excellent experience with those dips. Specifically thinking about just how much money a configuration such as this would cost This had not been the case for all games though, some like Dying Light 2 seemed to be great. The 1% lows weren’t a problem right here. The Thunderbolt arrangement was in advance in all pertains to at the higher 1440p as well as 4K resolutions, which is what I got out of all video games entering into the testing. Assassin’s Creed Valhalla was generally doing much better on the XG Mobile. The Thunderbolt arrangement was only a number of FPS in advance at the highest 4K resolution, and it was only ahead for the ordinary frame rate. The dips in performance, determined by the 1% lows, were lower on the Thunderbolt setup, indicating the XG Mobile is extra consistent with much less stuttering. City Exodus was unusual. The XG Mobile configuration reduced fairly a bit at 1080p when connecting an outside screen. I ‘d love to retest it and validate, yet regrettably ASUS needed it back a few weeks back so I had not been able to dual check. As a result of this suspicious result, the Thunderbolt

enclosure was ahead at 1080p for one of the few times. Microsoft Flight Simulator was usually behind on the Thunderbolt arrangement, unless you’re doing 4K pc gaming where it was reaching a 24% greater ordinary frame rate, but or else at 1080p and also 1440p, the XG Mobile was doing much better. God of War was getting to essentially the same typical FPS at 1440p, yet have a look at the differences in 1% lows, the XG Mobile is merely supplying a much more stable experience. Like numerous other games, the Thunderbolt configuration had the ability to triumph at 4K. Forza Perspective 5 on the other hand was much better on the XG Mobile in all resolutions, and also the dips in the 1% lows from the Thunderbolt arrangement were rather bad compared to what the XG Mobile is using. Typically over all 12 games checked, at the reduced 1080p resolution the XG Mobile was getting to a 42% higher ordinary framework rate. Just one video game, Metro Exodus Enhanced, was offering greater typical FPS with the Thunderbolt configuration, but as mentioned I had not been able to retest that. The XG Mobile winning at 1080p was my expectation entering, because the higher transmission capacity available to the XG Mobile matters more at lower resolutions. That stated, some of the insane results like Red Dead Redemption 2 and also View Dogs Myriad absolutely weren’t anticipated, something is incorrect with the Thunderbolt arrangement there. Tipping up to the greater 1440p resolution and also the XG Mobile was now 24% faster contrasted to the Thunderbolt plus desktop computer graphics card setup. We can see this number is mostly being held up by the top 2 or 3 video games. Then at the greater 4K resolution the Thunderbolt room was lastly able to provide an enhancement. The XG Mobile was now practically 8% slower in terms of average FPS out of the 12 games

examined. This doesn’t consist of 1% lows though because several games examined really did not gauge that, so it’s harder to directly contrast, yet as we saw those could often be far even worse with the Thunderbolt configuration. GPU heavy jobs beyond video gaming are less of a concern though, take 3DMark for instance. The extra powerful desktop graphics card in the Thunderbolt enclosure was in advance no matter the examination being run. In a GPU hefty tension examination, the Thunderbolt system had the ability to utilize substantially even more power, which’s why these GPU hefty jobs have the ability to do far better with the desktop card. It’s just that for whatever factor, whether that be PCIe transmission capacity limitations, power distribution concerns to the CPU, or a few other issue that the XG Mobile frequently does much better in actual video games. This wasn’t always the case though, particularly in content creator work. SPECviewperf was generally much faster on the desktop GPU, yet as we can see this wasn’t always the situation. Blender or food processor was faster on the desktop GPU in the Monster as well as Junkshop tests, but the Class examination was doing much better with the XG Mobile. Possibly it can profit extra from the higher VRAM capacity, I’m simply speculating, I don’t understand sufficient about these specific workloads to state. DaVinci Resolve is typically rather GPU dependent, but the XG Mobile had the ability to regularly score greater despite the Thunderbolt arrangement having the much more powerful desktop computer graphics card. The Thunderbolt arrangement has an even bigger defeat in Adobe Best, and after that a smaller difference in Adobe Photoshop, yet regardless it’s a win for the XG Mobile in these three designer applications. So regardless of the desktop card being more effective theoretically, I just can not suggest this configuration to any person seeking to purchase a Z13. The only exception would be if you’re very severe regarding 4K pc gaming as well as perhaps

you’re playing games that don’t have bad 1% lows. Yet also after that you would certainly still be handling every one of the other negatives stated. I just don’t think it deserves it for anybody. Are ASUS doing this to market even more XG Mobiles? Probably not. I indicate they’re extremely tough to in fact get your hands on for one point. Offering a device similar to this that can use either eGPU setup is an incredibly particular niche product. Is it possible that ASUS can deal with the continuing to be concerns with the Z13 and a Thunderbolt eGPU configuration? Definitely, however at this point I’m not actually as well certain. I’ve invested months of time troubleshooting this things with them and also I’m simply kind of over it, as well as I imply this is hardware that you can buy right currently. The troubles don’t seem to be simply for me either. A participant of my Disharmony server stated that they got the Z13 as well as attempted to utilize it with an RTX 3090 in the Aorus Video Gaming Box, as well as they couldn’t obtain it to operate at all. I believe they wound up returning it, and also that matches my experience as well, all type of arbitrary problems with Thunderbolt. Now that said, the XG Mobile from ASUS functioned perfectly in my own testing. Yeah lengthy tale short, I would most definitely recommend that over a Thunderbolt remedy. So currently that we understand that the XG Mobile is the means to go, ASUS really offer it in both AMD and also Nvidia setups. Discover which is better in this video clip over here following. I have actually contrasted AMD’s best RX 6850M XT versus Nvidia’s RTX 3080, however once more such as this video, there are problems to be aware of, so I’ll see you because one next!.
