Mantiz only has 87w for charging - Question
Common misconception here that even some very prominent Tech-Youtubers made in their early coverage. The battery has ~100Wh of capacity. In other terms, it can deliver 1W for 100 hours, or 100W for 1 hour. The charger rating can theoretically even be something as low as 10W and still charge the battery (even though that would take 10 hours not considering charging efficiency). In reality that does not work though because the MacBook itself is using some of the power from the charger for operation and the battery charging circuit has a cut-off charging current below which it won't charge. All those values, the minimum charging wattage and the peak power consumption of the electronics inside the MacBook Pro are unknown numbers at this point (to my knowledge). But I am very confident, that you can still use the device at maximum load and still charge the battery with an 87W input. It is only going to charger slightly slower than with a 96W charger.
Side note: If anyone that owns the new device (mine will be delivered on Thursday, I'll check then) could provide the average time the device takes to charge while it is powered off and while it is under load those missing values could be roughly estimated but that's just fooling around 😉
Note: This is just a very educated guess on the topic. There might be unaccounted factors like Apple software-locking chargers below 90W or other similar things but given that I was able to charge my 12" MacBook with a 30W nominal charging wattage with a battery bank that provides less than that (charging just takes ages) it is unlikely that the same doesn't apply for the new MBP.
Edit: When my MacBook arrives on Thursday I'll give it a test run with my 60W Type-C PD charger that I bought for the iPad / 12" and report back.
Edit2: I took a look at the spec sheets for various components. The i9-9880H has a TDP of 45W, the 5300M has 50W TGP which together accounts for 95W of theoretical peak power consumption. On top of that you'd have to add parts like the display, speakers and logic board consumption so ~100-110W of absolute peak consumption under full load is a realistic number. BUT that is the theoretical maximum consumption, in reality you won't be able to keep the CPU and/or GPU under peak load for even a second due to thermal system constraints. This combined with the fact that you won't have a sustained full load scenario under normal usage conditions leaves you with a lower average consumption which will very likely be below 87W (the fact that Apple included a 97W charger which is below the theoretical peak consumption of the internals shows that) and leaves some power to spare that goes towards the battery.
What a fantastic reply. Seriously. I sincerely appreciate that. I miss being that good at something.
With that being said, I currently have a Matebook X Pro 2018 w/ the i7 and mx150. So I know it would have zero issues charging and what not here. But IMO, the MBP 16 is leagues beyond what I expected them to deliver. I have been putting off getting a MBP again for quite some time due to the extremely lackluster GPU, keyboard, bezels, heat management, etc. The 5300 and 5500 are dream GPUs in comparison. So I’m looking at Spring time personally. But just wanted to make sure a Mantiz would still do the job. So I very much appreciate your reply.
I’ll also ask a follow on question. Ordered a Mantiz and I currently have a 1660 ti to roll with until I bite in the 5700 XT when I get the MBP. How much real performance loss am I going to see from the internal display on the Matebook X Pro 2018 w/ it’s 2x lanes w/ a 1660 ti? Are we talking downgraded to 1060 performance or worse?
Aww thanks for the kind words!
I’ve sold my 12” three months ago in anticipation of the new 16” but have been indecisive with the very odd rumor mill situation this time. Regardless I totally agree that even though the overhaul isn’t a complete redesign it is what the May 2019 15” was supposed to be. Especially considering the highly improved price-performance ratio in the discrete graphics and storage department.
Regarding your follow up question I can’t really tell you from any personal experience (the 16” + Razer Core + RX5700XT will be my first build) but judging by many benchmarks all over the forums I’d expect the 1660ti (which is roughly 25% above the 1060’s performance) to drop by about 25-30%, if not more due to the loop back to the internal display (since the Thunderbolt bandwidth is being shared between GPU usage and framebuffer transmission back to the laptop instead of going directly to an external display) and regarding the two lanes I’d expect maybe some additional 5-15%? Unfortunately I wasn’t able to find two builds with similar benchmark methods, the same eGPU and one having 2x and the other 4x to base this of off some real world data. Maybe have a look at the Builds table yourself, I bet there is such a combination in there *somewhere* ^^
I appreciate your quick reply and your input. I’ll have a look for these builds. To be honest - I’m not a huge gamer, just in spurts. My jam is usually Stellaris, Civ, or WoW. Everything else just doesn’t catch me anymore sadly. Not sure if it’s the 3 kids and happy marriage, or being 31 years old lol. The whole reason I got into this Egpu realm is because a gaming computer just didn’t make much sense anymore. However, a sleek portable school work and production laptop that can transform into a good time definitely made a little more sense lol. And I’m trying to switch back to Mac. I have a 2007 MBP, and then a 2015 MBP. My 2015 had some severe throttling and heat issues even after a repaste. And with the climate of the butterfly switches and frankly rehash after rehash if the MBP line - I went with a Matebook X Pro. By all accounts the Matebook X Pro has been fantastic, IMO Apple is the ONLY company (maybe razer) that builds better looking laptops.
I can totally relate to games not catching my attention anymore. Used to play a lot - probably too much - which somewhat drowned with my studies and work at the same time. The low amount of free time that comes with that is probably accounting for some part in that equation too ^^
In my eyes eGPU solutions are perfect when your main machine is for work / studies / daily stuff but you still want to game from time to time but not have an extra machine for it (even though the bang for the buck would be superior). At this point I could go on about a rant regarding Razer as a company but I'd rather not. Had some really bad experiences with their device build quality and how the support handled it. Besides I just can't stand Windows if avoidable and for daily usage (apart from software development) where "it just has to work" macOS is just the way to go.
The butterfly switches were definitely a grab in the trash though ... not that they had a bad typing experience but the reliability was just unacceptable which obviously lowered the market value of the machines (The 12" got sold for about half its original price after just two years of usage. My previous MacBook Air just dropped by ~30% after some solid four years of frequent usage).
Apple is just a very meticulous company when it comes to their products and this kind of polish and attention to detail is very rare these days especially in the tech world even more so when looking at software products.
