I'm just flabbergasted that Intel has Thunderbolt support integrated into it's mobile chips, but on desktop it's business as usual, left to motherboard vendors to implement Thunderbolt themselves with the normal slew of add-on chips. Super frustrating that desktop users can't expect modern connectivity. It should be on the chip, like mobile. Notably, one can take any old TB4 cable, connect two modern Intel laptops, a…

Is the 20Gbps on Rocket Lake’s integrated USB 3.2 Gen 2x2 “close enough” to TB4’s 40Gbps?

It's not USB4 so it can't connect to other computers. And it's already legacy, with limitations (no sharing mtiple streams on the channel, so no mixed DisplayPort). It's not Thunderbolt so it can't connect to thunderbolt pcie devices.

It's about more than the throughput. It's about usability. TB4 and USB4 both have some great usability leaps over USB3.

> My work desktop died on Wednesday afternoon during the SpaceX SN10 flight. What happened? I’ve never seen a computer die during use.

Spend enough time in front of a specific computer (or little time in front of a lot of different computers) and you'll eventually come across the same thing. In my (around) 20 years in the industry I've had (mostly laptops) die for various of reasons, most often the motherboard and screen giving out, but also the CPU and harddrives. Happened a few time with desktop computers that been 24/7 under stress as well.

Are these related, perhaps? I found the juxtaposition quite humorous.

Rocket Lake was designed for 10nm, but Intel couldn't get 10nm to work, so they backport Rocket Lake to 14nm. https://semiaccurate.com/2020/10/29/intels-palpable-desperat... Just filter out Charlie Demerjian's grudge against Intel. Companies don’t backport because a core is designed for a process. It’s efficiency and architecture is based on the transistors that it will use from the design start, caches are sized bas…

Grudge or not, it's not like he's been wrong the last few years. Turns out all the negativity is well justified...

Well he is also the guy who kept saying that the snapdragon 810 was fine well after everyone knew that it had major thermal issues.

Well USB-C/Thunderbolt rollout and HDMI 2 to laptops has been as glacial as ever. How is it that mobile phones get technology support two years before laptops and desktops?

Where is big money to be made, in laptops and desktops, or in overpriced phones?

You're probably right, but the Android market has it's marketplace pressures just like PC, and while I don't know the margins, I imagine Apple is making good margins on Macs.

It seems there IS a market for high end androids, but not for PCs, which really is an indictment of mainly Windows but also desktop Linux.

OP is implying the i5 was Pareto-optimal in terms of price and performance.

Exactly. In 2020 the 10400f was about 40% more expensive; now Intel is forced to lower the price of their entire lineup to compete against AMD. These days, at most performance tiers, Intel+mobo combo are slightly cheaper than AMD's equivalent. Of course, Intel's CPUs have less PCIE lanes, no ECC support, lessor upgrade path, generates more heat, etc. Finally my old desktop was Intel and I am working on a lot of kerne…

One big + for AMD is their socket system, and keeping it the same for multiple generations via a roadmap so people can plan. Contrast that with intel, who comes up with a new socket every generation forcing you to buy a new motherboard and likely new ram if you want to upgrade. AMD's Socket AM4 was released in 2016 and works with Zen+, Zen 2, Zen 3 and Excavator microarchitectures. If you upgraded every 2 years, that's 3 motherboards and memory sets you would have had to purchase if you went with Intel vs a single motherboard/memory and upgrading only the cpu with AMD. That's quite a premium.

And 104*C without overclocking! Sounds like they’re pushing the envelope.

They should drop in kettle stand as a free gift.

Seriously, it's basically a 700$ barbecue at this point. What's the Tj on this CPU ? 140 ?

> why the downvotes, HN? Your honest account seems more like a series of errors you've invited on yourself. Your motherboard prices are insane. And this litany of spontaneously breaking components make you sound like you're just yeeting the stuff around. Maybe that's all unfair, but it's how it comes across. Now you're comparing the prices of the i9-10900 to the 5900X, when the 5800X's performance more than matches i…

>Not to mention that the 10900 has a 65W TDP vs 105W for the Ryzens.

TDP is lie these days .The 65W intel chips will use over 200W in most motherboards.[1] The 10 core you're using will use even more. The 5900X would use 130W max.

Watch your temps, your passive thermal solution may not be up to the task and your CPUs may be throttling or dying prematurely.

If you had asked me about NVIDIA, since I run Wayland on Linux, I would have probably been much more biased. Regarding the last point, you can learn more about it here: https://wiki.archlinux.org/index.php/Intel_GVT-g Or, on their official GitHub Wiki: https://github.com/intel/gvt-linux/wiki/GVTg_Setup_Guide AMD's similar MxGPU is only available on Radeon Pro and their Workstation graphics: https://www.amd.com/en/gra…

Hello, Intel GVT-g is not supported on Gen11 and Gen12 gen Intel Graphics. It's only supported on Gen9 and earlier. About Intel discrete graphics: https://github.com/intel/gvt-linux/issues/160 > Internally we have some prototype but there is no formal plan to support GVT-g on discrete GPU like DG1 and about integrated later ones: https://github.com/intel/gvt-linux/issues/126 > until now there is no plan on it.

Thanks for clarification.
