Did you have a chance to try the eGPU?
-
For someone that prefer 17", 18" is the best size for 16:10, as the width of a 17" 16:10 screen is less than a 17" 16:9 screen.

Last post on this topic not to hijack it further, you are right. I didn't really follow what is being released, what is leaked and when and apparently HX was known for a long time. I am also not a gamer, so I check the market mostly only when I need a new computer to be used for software development and only need something that can compile large C++ projects fast enough meaning fast processor and lots of memory, and use an eGPU for seldom gaming. My mistake was thinking that there won't be any further more mainstream high end processor coming this year, otherwise I would wait a bit more and grabbed something like a Titan or Asus 17 SE. I think many people experienced that. Nearly all major gaming brands released a laptop with an HX processor which didn't happen before. This is why I call it messy and unexpected.
-
Firstly, this is the data for Xeon 11855M: As we see, it has a 8+4+4+4 configuration, unlike HX which is just a rebranded desktop processor. For the timing. We just had a "leak" of the RB18 data and at least I don't remember seeing any data for higher end mobile processors that early. Besides, at least for the gaming laptops it was a chaos as many that thought the H series was the limit of the mobile processors, suddenly HX popped up in the highest grade gaming laptops which was never the case before. Many that wanted to invest in a best performing gaming laptop suddenly faced a buyer's remorse.

Well, although it is a good and powerful processor, I think the release planning for the mobile 12th gen was a complete mess. HX processor based workstations are just going public and gaining some traction and we have the 13th gen desktop processors and 13th gen HX data in the market. Also the way they released it... They may have made a deal about PCIe5 but it is just an unused nonsense right now. The 8+8+4 configuration is another mess. How many dual GPU mobile systems do we have? None. Why not a 8+4+4+4 configuration? Because it is actually a desktop processor. I hope they make a better mobile HX next time. USB4.2 / TB5 is now a must for the 2023 lineup.

That Geekbench result is interesting though, especially coming from Razer, a company with a proven hobby of underpowering their high end CPUs. 18"? I for sure will pass if it is 16:9...

Looks like I should just stick to my RB17 for now. The problem is, I bough it as a work laptop and had to go through the Razer RMA and it was horrible. They told me that it will take two weaks and ended up like 6-7 weeks. It was a small issue and would rather not send it if I knew that it would be that long. So I am a bit nervous about it and thinking of having a problem and getting stuck like that. Anyway... I guess I have a really good 12900H chip, as it hits around 90-92°C on a hot summer day with over 4 GHz. The one I made today hit 88°C with Timespy CPU test. Here are my results with my eGPU. And here are the screenshots for temperature. And here are the performance results with my wife's undervolted XPS 17 12900HK with my 3090 eGPU. Although the CPU performance is better (I think dGPU was not disabled), eGPU performace is considerably behind. I will think about what to do on the weekend but the zbook is out of my radar for now now.

My Razer Blade 17 with 12900H and 3090 eGPU: What is interesting is the CPU thermal performance, below 90°C when running over 4 GHz. Of course, repasted with PTM7950 pads. I wish I could unlock the PL1/2, as I have the thermal headroom for it.

OK, I have been away from the PC architectrure for too long time (although I started as direct HW programmer before the 3D cards appeared, I have been doing mostly embedded and DSP programming nearly last 20 years), so I had to go and read about the DMI etc. I thought all PCIe lanes are directly connected to the CPU. Apparently HX series has 16+4 or 8+8+4 (total of 20) lanes, whereas H series has a total of 28 lanes. It is also interesting that, in your configuration they used x16 lanes for the GPU, whereas x8 should have been enough. I wonder what the configuration is for P16 G1. I think 8+8+4 is a weird configuration. Why not 8+4+4+4? Then I had a look at my Razer Blade 17 with 12900H. To my surprise, looks like it too has the TB connected not directly to the CPU.

...and as I was about to check the P1, I saw the Razer Blade 18 with 13900HX. https://www.notebookcheck.net/Next-gen-Razer-Blade-18-specs-leak-out-along-with-impressive-Geekbench-scores-for-Intel-s-i9-13900HX-mobile-CPU.667619.0.html

Ooooh, OK. Then for eGPU the HX processors are not really the best choice. I thought 12950HX has it but I just checked the specifications and integrated TB4 controller is really not there. This is for 12900H: And this is for 12950HX: That also explains the massive differences in Jarrod's video. Even a 1260P + eGPU performs better than 12900HX + eGPU.
-
What is interesting is that, the graphics card can be replaced. I don't have much experience HP laptops, so it is new for me. I wonder if it will work without the graphics card / dGPU.
-
This is sad on a workstation grade laptop.
-
Yes, thank you. A specific one, if you have an eGPU: Does the eGPU stutter on Linux (or on Windows) without turning off the dGPU? If yes, is it possible to turn the dGPU off? On Linux this might be done via ACPI calls. Thank you.
-
Interesting, not much is happening also here. Anyway, anyone using P16 with Linux and eGPU? If yes, any stuttering? If yes, any way to disable the dGPU on Linux via ACPI calls?
-
Interesting. Not many user experience or benchmarking posts. So far the Geekbench scores are not very promising. I wonder 8f they failed the thermals / tuning like the new Dell Precisions.
-
I still didn't order mine, as my mind was shifting between the other options and 7*70. Looks like Lenovo P16 out of the box has a considerably better performance but has no option for no dGPU, has only two nvme slots, and no ethernet. HP Fury G9 also doesn't have no dGPU option. Haven't seen many benchmarks either. I am also not sure if the support from Lenovo and HP is as good as Dell. Also looks like I might be able to completely turn off the dGPU on 7770 even if I go for a dGPU configuration (sometimes it is good to have a basic CUDA processor in the system). Then there is Asus 17 SE but my hand is already burned from depending on a gaming laptop for work. Hmmm... I need to sleep over my thoughts again.
-
The problem is with completely disabling it, as somehow if the dGPU is not completely disabled, the eGPU starts stuttering. I have this issue both on Windows and Linux, and on Windows eGPU stuttering stops if I disable the dGPU. On my Blade 17 and Linux, I couldn't manage to disable it with ACPI calls. This is mainly why I want to switch to a laptop where I can either disable the dGPU or completely remove it out of the equation. 7x70 are the only powerful laptops where I can choose a dGPU'less system.
-
Today I got my offers from two 7770 configurations from the Dell rep that I was in touch with last time I got the XPS17. Not a "US refurbished" price but still better than nothing. 😉 As said, I would like to order with iGPU only. Does it make a big performance drop using only the iGPU (as I guess it will use power from the CPU budget)? And any Linux users that succeeded to disable the dGPU completely?
-
Unfortunately I am in Germany and there are not so many options here. There are no refurbished 7770s, especially at that price. The ones (mostly the 15" variant) are not really cheaper than the new ones. And Dell doesn't seem to be shipping US items to Germany. But thanks for suggestions and help.
-
I play games very seldomly and not too picky with the FPS but with 4x nvme slots, it would be a sin at least not to try it. 🙂Thank you for the detailed information. That is wonderful news. So, it will be 7770, then. I haven't checked how it is in the US but here in Germany 64 GB SO-DIMM costs €300, whereas 64 GB CAMM costs €1000. So I want to order one with 1x8GB and add 2x32 GB myself. Good point, thank you. One more question. Do you think 12950HX makes sense over 12850HX? It is extra €400 which I am not willing to pay for a 3% increase of performance.

Hello all! My first here. 🙂 I would like to get a desktop replacement laptop with an HX processor, mainly for work. I am an eGPU and Linux user, so actually I am not even interested in having any dGPU. 12800HX and 12900HX processors don't have a built-in TB4 controller, so the eGPU performance is quite lower than a lower grade CPU with a built-in TB4 controller. It looks like 12850/12950HX are the only processors in the HX line-up with integrated TB4 controller. That brings me to 7670 and 7770. I guess not having any dGPU would help thermals a bit but still looks like to unlock the full performance a repaste and BIOS unlock is necessary. I was actually thinking of applying PTM7950 pads to the sides of the CPU as a barrier and applying LM to the middle actually most of the surface area - or maybe just 7950 for the whole surface. To my questions: 1. Has anyone tried a 7x70 with an eGPU, especially under Linux can say anything about the performance? I currently have a Razer Blade (RB) and when I use an eGPU, I see some stuttering with eGPU, which is also happening under Windows and can be mitigated only by disabling the dGPU. On RB and Timespy (Windows), I get around 16500 "GPU only" score with a 3090 eGPU, and the 12900H performs around 14300 (CPU only score, optimus disabled). Unfortunately, I couldn't manage to disable the dGPU with acpi_call method so far with RB - which has an awfully limited and non-standart BIOS / ACPI implementation. I would expect Dell to be better in that sense. 2. As I understand from the internal photos 7770 has 4 SSD slots and 7670 has 3. Am I right? 3. I would like to order with SO-DIMM modules. I can only order with two sticks, but does that mean it has only two slots for SO-DIMM configuration? 4. For the thermals, how does 7670 compare to 7770? Does it make sense to order 7770 instead of 7670 only for the thermals? 5. I have the option to order 180W or 240W power supply. I think, without a dGPU I don't think I need a 240W supply. What do you think? Thank you. 🙂
