I've been wondering recently if there isn't a method of doing this flipping the motherboard and having a custom block which flows the nitrogen under (but still touching) the 'bottom' (now top) of the block ... which is obviously also still cooling the CPU easily.
Or perhaps letting it pool, then tipping slightly for runoff and new nitrogen. Rinse. Repeat. Literally.
This could probably be automated by someone like der8auer and done according to actual maths regarding everything, but also when the nitrogen is shown to be slowing in the cooling ... then the automation empties and refills.
Either way, the 'upside-down' would help a lot with much of the condensation (not all), but also spills, spits, and drips. :-)
---
I suppose the big issue would be heat going the other way ... but if there's a board with minimal important stuff on the other side, perhaps a slow, slim, flow over the 'new top' just to take care of extra shit ... but not to cause too much condensation.

Excellent video as always and glad to see further performance competition which is great for the consumer market. However, Considering the 12900K currently costs 499.99 at Micro Center and the 7950X is expected to cost 699.99, The 7950X processor itself costs approximately 40% more money than the 12900K, So shouldn t this end result be otherwise expected? This is also completely overlooking the fact that the 7950X absolutely requires DDR5 RAM while the 12900K can use either cheaper DDR4 or DDR5 memory. If we are for simplicity sake looking at build cost for a DDR5 setup and saying that the 439.99 Z690 Taichi and the 500+ X670E Taichi motherboards cost the same exact amount to keep things equal for simplicity sake (Which they don t cost the same) and the RAM is shared across both setups for simplicity sake, The AMD build here costs more money and should outperform the cheaper Intel build. Great test and great results, but no surprises here.

So, whats the point of this? Apart from being cool that its a record and all, and in no way is that sarcasm, what does it do for you? Why overclock like that? Because, to be honest, I'm having a hard time as it is just keeping my laptop cool. It gets soooo hot even with a decent cooling fan pad under it and the AC register 3 feet under it blowing right up on it. I cant imagine overclocking this thing as my understanding is it will run even hotter. Ive got an AMD Ryzen 9 5900HX with Radeon 3.30GHz (32GB RAM). When I run MW5 or Roguetech on it it gets HOT. Hell, even upgraded Diablo2 makes it uncomfortably hot to the touch.

As cool as liquid nitrogen looks. I'm a little hard pressed to get my hands on some. I would VERY MUCH like for heat sinks to improve (new material science??) I hear they're doing wonders with carbon nanotubes (eg etc). how bout more cross-fire? or maybe some VRAM unlocking, or exporting some of the inactive background redendering to an SSD through driver tasking? The tech exists, right now we're just having trouble with price points, and RESPECT FOR THE CONSUMER (not so much AMD, but pretty much everybody else).

Looks like the high end is in great shape. That bodes well for the platform overall, at least for performance.
Hoping for more info on the low end eventually. If those have okay price and availability it could really bring the low end back into play with the more minimal iGPU bringing down cost. If AMD really wants to use their silicon for those lower-margin products, that is... I hope so. The low-low-end hasn't seen first-class options since Ryzen 3000 series.

Steve may attest to this, ladies and gents we are living in a time where there are several options to meet multiple needs with several manufacturers. If this is not the time for a company like AMD, with the transparency and idea to experiment, to run roughshod on the general consumer market in both the CPU and GFX sector, then I don't know when it will be. Various options for different price points without the gouging. I've been in since 2700x and I'm mad hype.

I love the way clock speed is making a comeback, I mean I can get 5Ghz all day on my 2600K, especially if I use a modern cooler, I usually have a Dark Rock Pro4 on it, but I have also used a Arctic Freezer II, yet everyone was getting excited when they could get 5Ghz all core on 9th gen. Alder late can get some impressive clock speeds very easily, it's just impossible to cool, but it looks like the next gen from both teams are gong to make 6Ghz the new 5Ghz.

Why do the clickbait like that? New is expected to trump old. Wait for 13th Gen and compare apples to apples So we can get a proper comparison. 12900k is not dead because of new CPU its still a great Chip and will most likely cost less now with 13th and AMDs new offerings. Previous Gen AMD is almost 4 years old if not. So you would expect a massive leap in that time whereas Intel is almost producing a new chip a year with incremental steps in performance.

TBF the only thing I keen to see it home set temps on the 7950x and 13900.
Game wise it will be like last gen, almost neck and neck with Intel slightly better in a few games, and power wise I don't really care because I will be running a 4090, so it's going to be high anyway. But, what will make me swing to either company is how hot the chips run and how that will effect case temps, throttling, and because of layout, gpu temps.

For anyone wondering: it is safe to handle liquid nitrogen with bare hands. It's actually dangerous to wear gloves.
The reason being that when wearing gloves the nitrogen can soak into the glove and burn you. When liquid nitrogen splashes into bare flesh it actually evaporates and forms a protective barrier around the hand which stops more nitrogen from soaking onto the skin and burning you.

Just for comparison, according to hw bot cinebench r20 scores, a 7950x at 5.35ish GHz is 25% faster than a 12900ks at 5.35ish GHz. Don't know how well cinebench R20 scores scale, especially across CPUs but it may show a 25% clock for clock performance lead for AMD. Hopefully 13th gen processors are close to or exceed 25% IPC or clock uplifts to compete against these new AM5 chips

Here is the Hypocrisy, All the tech companies in silicone valley rally for environmentalists yet every generation power efficiency goes out the window for performance . They fund and lobby for politicians that mandate i use less power but want me to buy their products. What the fu k i n Lunacy. AT least a dog smells its own ass and knows it stinks

I don't see any interrest in LN2 cooling for end users. If you're an enterprise you'll do it as it should be. If you're a Uber Geek yeh, there may be an interrest seeing big numbers on screen.. For 1 min !
I personally don't have any interrest in OCed machines that cannot be used and by used I mean compile entire Gentoo/Funtoo in one shot.

Liquid helium would get temps quite lower.... if you can stop it crawling out of the pot that is... I am curious if some quantum weirdness will occur and result in a CERN-level BSOD... but then again, I know little about XOC, so maybe it's been already tried, despite how expensive it would be. At any rate, thanks for covering the nerdy stuff!
