Would a 4TB SSD be supported?
In the specs only SSDs up to 2TB are mentioned.

Here is my follow up:
The broken trackpad has been repaired by Lenovo and is working ok now.
The camera didn't crash any more on both laptops since I installed Windows 10, i.e. the problems were due to Windows 11.
I like the laptops, because they don't get hot or noisy and the screen is large and has a 16 x 10 ratio. The keyboard could be better (I love the T420 keyboard...). I will keep both T16 AMD laptops.

Thanks for your feedback! Both T16 came with Windows 11 which seems not to be mature yet. I just installed Windows 10 on one of the two laptops and the camera seems to work now! Concerning the broken left trackpad button: I guess I will try to let it be repaired by Lenovo. Fortunately, I have the premium support, where the technician repairs the device on-site. I keep you updated...

Quote from: Thomas957 on February 08, 2023, 23:02:02I just bought two T16 AMD Gen 1 and have a lot of trouble with the camera (freezing after a few seconds) in both devices. And one has the problem described in the article, that the left trackpad button does not trigger correctly. I cannot event use the scrollbar of a website: while moving it, at some point the "mouse down" status is lost and the scrollbar stops moving.

Otherwise, I like the laptops. But the quality control seems to be really bad and I think of returning one or even both...

Anybody else with camera issues?

Contact customer service and ask for a repair, in case it is a hardware issue (trackpad). For the webcam I'd assume a software fix.
If you are still in the period of potentially returning it, I'd send in writing that there is a defect and that you ask to repair. In case they can't repair it, you are eligible to a return or refund or discount, depending in your jurisdiction.

Not to mention the fact that the level of hardware and software developers (like the entire scientific world) is rapidly degrading (including moral and ethical principles), which affects more and more architectural flaws and multiplying security holes (and soon existential threats), like cockroaches on dirty kitchen. Because this requires a quiet life and a comfortable social and economic environment for several (consecutive) generations of people, and now it is being systematically destroyed all over the planet, reversing all the social achievements of mankind and an effective global division of labor and science. Step by step, turning the whole world into "managed" chaos...

Lenovo constantly has problems in other series with mechanical webcam shutters. So it's just another problem in the piggy bank in different parties.

After what happened to the world in 2020 and beyond, forget about quality control from factories and integrity checks. The world has become different...you, as a buyer, have now become a permanent beta (or even alpha) tester...

In this case, your assertions that Intel, and even more so AMD, allegedly cannot make 128-bit controllers with a frequency of 6400 simply do not hold water. Since Apple can provide such super speed in their laptops (although I have never seen such numbers anywhere and first learned them from you, so I still need some official proofs), then for AMD, at least with TSMC, this is not a problem, not to mention for Intel. But we have, in fact, a shameful memory speed in all x86 processors without exception. 10 times worse than Apple in average. That is why both Intel and AMD, as I have already written many times, are desperately increasing L3 cache (which Apple does not really need to do at such a speed)

With what it can be connected? Bad development teams for x86?

it's ofc GByte/s. Our data base has it wrong, wikipedia and the other source have it right. The original Apple screenshot, which is shown in the first link, also says GB/s, not GBit/s.

should be fixed in our database very soon, btw.

So 400Gbit/s or 400Gbyte/s? If 400 Gbit/s, then this is a shameful 50Gbyte/s. And it turns out that Apple has slow memory and Intel is king in the market in terms of its speed with 80GByte/s (640Gbit/s) in Yoga Pro with 12700H and LPDDR5 5200 128 bit bus.

You have some data confusion.

Sure, we have the info in our database, too. It says "fast LPDDR5-6400 unified memory with a 512 bit bus (up to 400 GBit/s)." https://www.notebookcheck.net/Apple-M1-Max-32-Core-GPU-Benchmarks-and-Specs.579797.0.html

I'll link straight to a deeper analysis, which states that the full bandwidth could be reached if CPU, GPU and media engines stress the system at the same time. for cpu loads only the full bandwidth isn't used: "While 243GB/s is massive, and overshadows any other design in the industry, it's still quite far from the 409GB/s the chip is capable of. More importantly for the M1 Max, it's only slightly higher than the 204GB/s limit of the M1 Pro, so from a CPU-only workload perspective, it doesn't appear to make sense to get the Max if one is focused just on CPU bandwidth."
Source: https://www.anandtech.com/show/17024/apple-m1-max-performance-review/2

Wikipedia: "The M1 Pro has 256-bit LPDDR5 SDRAM memory, and the M1 Max has 512-bit LPDDR5 SDRAM memory. While the M1 SoC has 66.67GB/s memory bandwidth, the M1 Pro has 200GB/s bandwidth and the M1 Max has a 400GB/s bandwidth." (https://en.wikipedia.org/wiki/Apple_M1)

Thanks for your Gear explanations!

About Mac, I know too little about unified memory to judge.

Quote from: Marvin Gollor on February 03, 2023, 18:00:17I didn't state that (M1 Max) MacBooks feature 8 times faster memory, I just stated that it's connected to a 512 bit controller and therefore has 8 times higher bandwidth on paper than if conncted to 64 bit. In reality the bandwidth isn't always maxed out, also the case with x86 systems.

But still...You have already done your own work by finding this data and know the sources of this information. Could you provide links to this?

Quote from: Marvin Gollor on February 03, 2023, 18:00:17I guess 5200 is fast enough for intel for now, considering the additional costs.

I know for sure that it isn't. But they just can't seem to get better.

Quote from: Marvin Gollor on February 03, 2023, 18:00:17Just because Apple finds a way for its high-end macbooks, doesn't mean AMD/Intel is able to copy Apple in this regard from a business standpoint.

Don't you find your argument illogical and absurd considering the prices of expensive x86 solutions? Why is there no HBM memory? Or a 512 bit controller? I have already given an example of the new 7945HX, which is simply catastrophically short of memory bandwidth, at least 3 times (and this is purely bad based on my empirical experience and data).

Quote from: Marvin Gollor on February 03, 2023, 18:00:17AIDA says 128 bit

Thank you. Q.E.D. AMD has a shameful memory controller in Zen3+, I can't say anything about Zen4, but as I already noted, for some reason, the younger Phoenix "4nm" chip has 256GB of memory available, and the top 7945HX with 28 pci-e 5.0 lines has only 64GB.

Quote from: RobertJasiek on February 03, 2023, 15:41:06Please explain!

In Gear1 mode, the frequency of the memory controller is equal to the frequency of the memory, i.e. 1:1 ratio in Cpu-Z. In Gear2 mode - the memory controller runs at half the memory frequency, the ratio is 1:2.

The main gain is not in memory bandwidth, but in memory latency. It speeds up by about 20-25% in atomic (no longer divisible into separate operations) operations. This has a significant effect in some software.

DDR4 works well in Gear1 up to 3733. But most laptop manufacturers deliberately include Gear2 because Gear1 consumes more. It doesn't matter from the outlet. But slightly increases the processor heat, enough to make the coolers noisier. For these reasons, Gear2 is used most often (except for workstations). On desktops, this is the first thing on which you can overclock the memory, with good stability.

Quote from: RobertJasiek on February 03, 2023, 15:41:06As to HBM, don't you think that it consumes too much power?

Marvin assures that Macbooks use an analogue of HBM with a 512-bit bus. What do you think - is there a strong growth in consumption or not? And is the battery life of the laptop less or not?

I didn't state that (M1 Max) MacBooks feature 8 times faster memory, I just stated that it's connected to a 512 bit controller and therefore has 8 times higher bandwidth on paper than if conncted to 64 bit. In reality the bandwidth isn't always maxed out, also the case with x86 systems.

Morevover, I didn't say Intel is unable to make a wider mem-controller, I just stated they're just not using 64bit LPDDR5-6400-RAM. I guess 5200 is fast enough for intel for now, considering the additional costs. Yes, AMD doesn't use wider LPDDR5-6400-RAM on most machines to reduce costs or it's too difficult to justify the work, yet. Just because Apple finds a way for its high-end macbooks, doesn't mean AMD/Intel is able to copy Apple in this regard from a business standpoint.

For me the most interesting thing would be if the Steam Deck, which uses LPDDR5-5500 RAM with 32 bit per channel, reaches the advertised bandwidth of ~80-88 GB/s or if it stays below LPDDR5-6400-RAM at ~40-50 GB/s.

If the last is the case, AMDs mem controller really is BS but if the Steam Deck reaches ~80 GB/s, then AMD either uses a different mem controller for the steam deck or wider LPDDR5-RAM. Couldn't find any RAM benchmarks of a Steam Deck, though. We could derive it by the rdna-2-performance while knowing how this gpu scales with additional bandwidth, which is: ~20% more performance with ~30% added mem-bandwidth. And it turns out that the Steam Deck isn't faster in Games than an AMD 6800U+680M Laptop. It may indicate that the LPDDR5-5500 RAM is wider than LPDDR5-6400 on AMD Systems since rdna2 profits from the higher clocks of the last, which could means that the first could feature more bandwidth to compensate and reach same fps in games. But  could be to vague without actual mem-benchmarks.

AIDA says 128 bit but I am not necessarly trusting any software in this regard, as CPU-Z states wrong things as well. Would be extremly odd imho if the actual bandwidth would be 102 GB/s but we're reaching just the exact half of it. From what I read the mem-controller may be 128 bit but the memory itself just features 64 bit in total. But I am not sure at this, because I get too less info out of the net so far.

there is sitll the point, that regular DDR5-4800-RAM ist up to 30% faster in AMD machines than LPDDR5-6400-RAM which would be very odd, too, if both RAM is as wide as the other.

"the mode of operation of the memory relative to the frequency of the memory controller - Gear1 or Gear2."

Please explain!

As to HBM, don't you think that it consumes too much power?
