TIL that there's such a thing as a 'grandmaster overclocker.'

I also learned that literally pouring liquid nitrogen over a CPU from a cup is a grandmaster overclocker move.

If that's true, how would one rank pumping supercritical liquid nitrogen at high rates through a heatsink? Super-grandmaster?

Seems like the heat flow would be substantially impeded by any boiling of the LN2.

Or, for that matter, simply using a chilled copper ingot as the heat sink? There must be some threshold at which the limiting problem is getting the heat out of the die, not getting the heat out of the chip's package.

They also screwed a cool little tower on top of the CPU and are wearing a Doom helmet. Don't under represent their mastery.

With no gloves, to boot!

Of course, the real grandmaster move is to use liquid helium - its boiling point is about 70C colder than nitrogen :)

TIL processors can actually hit a stable 6.6 GHz if you just pump liquid nitrogen through them…

Cant wait for my 1000hz monitor!

My last CRT Iiyama monitor had quite a refresh rate - 120Hz or more - and the picture looked absolutely gorgeous.

It weighed a tonne and took up quite a lot of desk.

What is interesting, from the screenshot, is that the game is actually CPU bound. Contrary to an often held belief in the high-end video games optimization circles.

You can just lower graphics settings to get more out of the GPU, but there is no CPU equivalent to that like "lowering AI quality".

I’d want motion blur on then for super natural looking motion

No. I just bought a 4k screen only to find out that 12k is coming down the pipe. I do not want to think about what 1000hz 12k screens will cost. Stop this madness now.
[+] smabie|5 years ago|reply
No one is gonna make 12k at 1000hz for decades, at least. And if they do, it would be irrelevant without a comparable GPU.

A RTX 2080 Ti can't even push 144fps on 1440p at max, much less 4k.

Something is always coming down the pipe. Fortunately you have need to walk the treadmill, and if you're only just getting a 4K screen now, then you're probably not the kind of insane early-adopter who is.

12k is possible but it's hardly around the corner. Even 4K has both content and hardware issues around it. 8K is going to be the next mass market push but we're not even done with the 4K party.

Also 4K display devices are available at a modest price point now. The bigger issues are content. We're mostly there with mass-market media, but if you want to drive a AAA video game at 4K resolution you're having to make compromises and spend a lot on the hardware to drive it.

They're going to keep making new things. And the new things are going to have bigger numbers. It's okay.

You aren't obligated to own the highest spec hardware in existence.

Frames per second is not the same thing as your display refresh rate. Further, I'm not aware of any monitor capable of 1000hz operation.
[+] dyingkneepad|5 years ago|reply
12k? Never heard of. Let's go with 8k, which is 7680x4320.

Assuming our current standard of 8 bits per color with no alpha (3 bytes per pixel), which may be too low if you care so much about your monitor, your required bandwidth becomes:

7680 * 4320 * 3 * 1000 = 99532800000

99532800000 / 1024 / 1024 / 1024 = 92 gigabytes per second of bandwidth you will consume just to pump stuff to your monitor. Better not use integrated graphics!

To give a comparison, here's 4k@60hz:

3840 * 2160 * 3 * 60 = 1492992000

1492992000 / 1024 / 1024 = 1423 Mb/s.

Also notice that 8k monitors already employ tactics such as "visually lossless compression" (which means: lossy compression but they think you won't notice) and other stuff aimed at trying to not really submit full frames all the time.

Forget your 12k. It will only be useful to increase your energy bill.

Edit: fix calculations.

At some point, it’s not worth upgrading resolution. I don’t know what that point is for you; but, eyes only have a certain arc-length resolution, beyond which everything additional as far as resolution is meaningless.

For me, that’s a bit more than 1440p at 3 feet at 27”.

Neither your eyes nor your brain would be capable to cope with that.
