dGPU stays on when it shouldn’t. I’ve posted about it lots before. With hybrid graphics on, try just disabling and then enabling the dGPU in Device Manager and see if that fixes power draw and temps. I have this scripted to happen 2 minutes after I log in to fix Optimus. The dGPU might be on even if the NVIDIA status icon thing is showing gray/off. An easy way to check is with Dell Fan Management. If it is showing a temperature for the dGPU, it is on. If it is off, it will show “—“.

Yeah, so I see "Dynamic Boost" showing enabled, but there should be a separate entry for "Dynamic Boost 2.0", which I am not seeing.

Is your system showing that Dynamic Boost 2.0 is available? Mine is not. (It should be an entirely separate entry in the NVIDIA "System Information" panel... I've seen it in my Precision 7560.)

Ha. Don't get your hopes up. I think Dell thinks that their primary market for these systems (larger businesses) want to see both the power brick and the system chassis becoming smaller, not larger. (They're probably right.)

I think twice the E cores will be fine. Will it work with higher power limits (overall) or clock speeds than Alder Lake / 12th gen? No. Will it be faster, as in, get more work done in the same amount of time overall? For fully multi-threaded loads, likely yes. More cores running at lower power levels (per core) is generally more efficient in terms of performance-per-watt.

Rumored specs showing AD103 as the top GPU for laptops next generation, and NVIDIA could indeed be naming it "GeForce 4090" despite the same 175W limit that we are seeing for this generation. (Top pro 5000-level GPU will likely match specs with whatever the top consumer mobile GPU is.) https://videocardz.com/newz/alleged-nvidia-geforce-rtx-40-laptop-gpu-clock-and-tgp-specs-emerge I'd say that this means that there is not much room for a mid-generation GPU upgrade in the 2024 systems. (I seriously doubt that NVIDIA will try to shove an AD102 GPU into laptops.)

Thanks for the heads up. I updated the OP to reflect this. Coming back to this one... My fans are Delta, not Sunon. (I have not yet had the assembly replaced. Not sure if I will, since I have things working good for now.)

Alder Lake HX also had a 157W upper limit. I think that the power efficiency at lower power levels is not bad, especially with the E cores in play... But, obviously more power = higher performance and competition is forcing Intel to raise power limits in order to stay on top of the performance charts. I suppose they figure you'll buy an Alder Lake "P" or "U" CPU if you want a system that gobbles less power .....? Heck, even the Alder Lake U CPUs have up to 10 cores / 12 threads and can turbo boost to 4.8 GHz. (Dell offers "U" CPUs in the Precision 3000 line.)

AFAIK, no laptop manufacturers are putting MXM cards in current-generation laptops anymore. You can find "standard" Turing and Ampere MXM cards (T1000/T2000/A1000/A2000), but they are more built for small embedded systems and "happen to work" in some older laptops with MXM slots. (They are also hard to find and expensive when they do pop up.) Higher-end cards like A4500 exist but are even more difficult to come by. I don't recall seeing a GeForce MXM card since RTX 2080 and those were wildly out of spec in terms of both size/shape and power requirement. High-end GPUs have moved beyond the MXM spec (it was designed for around 100W TDP max, and it can be pushed a bit higher than that... but Ampere GPUs can pull up to around 175W). A modern standard has not emerged. Laptop manufacturers are happy to either solder GPUs directly onto the motherboard or use proprietary cards.

It says "Raptor Lake" laptops will be available before the end of 2022 (Intel has stated this in the past) but it does not say that about the HX line specifically. I'm sticking with my earlier projection. We'll hear about lots of systems with Raptor Lake H at CES (coming up soon) that will probably be launching throughout first quarter 2023, but Raptor Lake HX will be a few months further out still.

You are right. I missed the desktop-vs-laptop comparison. (Though honestly, we don't know what type of system the CPU was in when it was benchmarked. It could even be in a development board with a desktop-style cooler. We'll have to still wait and see how it performs in various specific laptop models.)

13900HX shows up in Geekbench. 8P+16E (as expected) and about 20% faster than 12900K in a multi-core benchmark. (It looks like the additional E cores are where the boost comes from, because the single-threaded benchmark shows an almost negligible gain.) https://www.tomshardware.com/news/13900hx-outperforms-12900k-geekbench-5

Interesting that the system boots with nothing in the DGFF area. Precision 7X30-7X60 would fail to boot without a dGPU, or the iGPU pass through card. (In these systems, the mDP and HDMI ports were physically on the dGPU card, so the iGPU pass through card was needed to pass those ports to the integrated GPU.) I wonder what the iGPU spacer card actually does in this system…?

Twitter has been profitable before (which makes me seriously question Musk pitching his deep cost cutting as "necessary"). Of course, all of the advertisers that have been leaving the platform probably aren't making things look good for this year and next... Since Twitter is private now, we might not even get to see good numbers. Oh, plus Twitter owes $1 billion per year in interest payments now, that'll surely eat in to any sort of profit they manage to generate...

Because he's doing such a great job of that himself... The new "no linking to other social networks" policy (linked above) has been deleted, as were the "official" tweets announcing that policy change. Now, the Twitter Safety account has taken to posting polls asking about potential changes to the rules... https://twitter.com/TwitterSafety/status/1604657989977260033

This is normal. The DGFF connection between the GPU and the motherboard is just eight lanes. There are not enough pins for 16 lanes. This was also the case for prior-gen Precision 7X60. Some older systems did run at 16 lanes with an extra DGFF data connector. PCIe4×8 has the same bandwidth as PCIe3×16, so I think that Dell took the opportunity to free up some board space rather than increase bandwidth when the PCIe4 upgrade came along. Ampere doesn't really need 16 lanes of PCIe4 to reach full performance (especially when you consider how power-starved the GPU is in this case). This is also normal. Under standard configuration, the PCIe link speed will change dynamically, you won't normally see it running at PCIe4 speed unless the GPU is doing work. (You can override this behavior with Windows advanced power settings... but there's no real reason to.)

Maybe this will be over soon? (Ha.) Elon Musk proposes stepping down as head of Twitter in poll https://www.theverge.com/2022/12/18/23515764/elon-musk-head-twit-poll-tesla-doxxing-moderation Here's the poll. As of now, the vote to remove Musk is ahead at 58% vs 42%. https://twitter.com/elonmusk/status/1604617643973124097 [Edit] Musk also says that they're going to tweak the policy above blocking links to Facebook, etc.; they will only do suspensions when the account's "primary purpose" is promotion of a competitor. https://twitter.com/elonmusk/status/1604615711036407809 [Edit 2] I haven't been following the Tesla side but it looks like he's under pressure to move back over there (at least if he wants to keep his CEO title), so this poll might be the perfect excuse for him to get out...

I don't think the power adapters will be cross-compatible. A1297 has the original MagSafe connector and MacBook Air 15 has MagSafe 2. You don't need install media for macOS. The system BIOS has the capability to pull it down on-demand over the Internet. Hold the "Command" and "R" keys while you power on the system and you will get to a recovery mode where you can reinstall macOS. (You may have to select a Wi-Fi network and enter the password if you do not have the system connected via Ethernet.) https://support.apple.com/en-us/HT204904 Once macOS is installed, you will be free to upgrade it to the latest version supported on the system using the regular online process. (Newer systems are upgraded through the "Software Update" component in system settings, but older ones actually had you pull down the new OS through the App Store.) ...I looked up the model information. A1297 is rather old, that model was released in 2009. The latest officially supported OS is Mac OS X 10.11 "El Capitan", released in 2015. You might be able to upgrade to a later release "unsupported", this site has some information on that. http://dosdude1.com/software.html

It doesn't necessarily run the CPU at maximum power just because it's running at the maximum clock speed. (...Though, it would use less power if it were allowed to clock down.)

Alright, here's some more. Elon Musk is offering the generous opportunity to invest in Twitter at $54.20 https://www.theverge.com/2022/12/16/23513407/elon-musk-equity-investment-sucker-born-every-minute (After admitting that he "obviously" overpaid for Twitter, he is offering up the opportunity for other people to hop in and overpay as well!)
