Is the modern CPU power even a limitation these days unless you're running an ancient system?
Seems like the graphics card is the modern bottleneck....

If things continue on their current trajectory top gaming PCs will have to plug into two phase power in four or five years. There are already 2000W power supplies out and 1200W supplies are the standard now for competitive PC gaming. Right now you can have a dedicated line on a 20A breaker and probably be okay with up to 2000W. If the solution in the future goes back to SLI/Crossfire and top GPUs continue to use over 600W I suspect we will start seeing two-phase power supplies appear.

So much so and right arm! I've known folk who have two power supplies in their gaming rigs, but it is not an easy project and can lead to fried MBs, CPUs, graphics cards, etc., and suchas. It can be done, but I am NOT going to try it!

So at 6 GHz, electrical signals propagating at the speed of light will only travel ~5 cm in one clock cycle. Sounds like the Core i9 dies are about 2.4 cm in the longest dimension. We're going to start bumping into speed-of-light constraints if clock speeds go much higher (and you're definitely not going to get bus speeds this high with the much larger size of the board).

Probably not for a while longer at least. Those are peak outputs for the supplies, not typically what the system draws constantly. Even during gaming on top end graphics cards and systems, the overwhelming majority of people are still going to be <1000 watts.

For real. I just checked. My 5900X with a liquid cooled 6800 XT, with surround sound and 3 monitors plugged into it, in addition to my steering wheel that has a 480W PS, it only draws 680 watts at peak during a race. That's the entirety of my gaming setup, 680W

Right now. When CPU is pulling 300, GPU is pulling 600, the rest of the motherboard is probably eating a combined 100. You will need a 1200W to handle that (and 4090 references are already recommending it). Just add SLI and also add even more power for two more more generations (6090ti) and plain old 110V won't be able to handle it.

Bruh, thosee  recommendations are based on potential peak usage. Here is a screenshot of a 4090 with an i9-12900, drawing 400w.

And my gaming machine that has a 165W TDP CPU, only draws 680 with gobs of other shiat running on the same circuit.

I just don't see it happening any time soon.  I've been tracking my gaming PC power draw for about 15 years now.  The very highest peak was about 12 years back during the heyday of Nvidia's era of SLI, my 2600K+3xGTX580s were drawing 1015w during the worst case gaming scenario as measured by a device sitting between my entire PC (triple monitors and all) and the wall.

Since that point SLI started to die off and each system I had drew less and less, today my single card system caps out at ~650w again with the same device between everything on the power bar and the wall.

Sure this current gen top king-pin GPU from Nvidia is throwing far into moar power land but that's not the trend, it'll get reigned in and nah there aren't gaming desktop CPUs that could draw 300w, and during gaming let's be honest they're barely doing anything compared to the GPU, maaybe 75w draw at most.

SLI ain't coming back either, that ship sailed and as someone who really bought into it for years with many sets of GPUs on my wall to prove it, I just don't see it.

Where I can see that starting to rub up against the limits though is Workstation PCs.  The kind with dual CPUs and Workstation class GPUs, that is still a (rare) application for more then one GPU in play too.

But I still think the 4090 is a one-off Frankenstein that Nvidia pulled out of their asses to fend off AMD clearly eating at their lunch on the top-tier on a watt/performance benefit.  We won't see more of those, at least in pleb-level PCs like gaming applications.

Geez. And I thought I was nuts for going the other direction and underclocking and undervolting things lol. I make those Windows lower power profiles for my desktop (the ones they include buried in Windows for laptops). Use PBO in bios to undervolt my 5900X too, even got my RTX 3060 down to 80-90W peak. Still games great for me, lower noise and heat too. I'm probably under 400W entire system and TV.

My Threadripper 3960 has an RTX3060 and an Intel A750 GPU and if I somehow managed to get EVERYTHING hitting max TDP all at once, it tops out at around 1100W from the wall. Intel is making "mainstream" CPUs that exceed the power draw on workstation products and honestly y'all shouldn't tolerate that. This is not a thing that should exist.

What's the overlay doohicky?  I'd like to know what mine draws (3600/3060)

Looks like MSI Afterburner's UI but there's lots of them.

Meanwhile if you want a hardware solution that can be inserted between the wall and say the powerbar providing all of your system's stuff, these Kill-A-Watt things are great:

It was eye-opening what my various not-PC related devices were drawing vs my perceptions of them for instance.

Except your Threadripper 3960x cores are slower core-for-fore than the i9 stuff Intel's been pumping out lately. Parallelism is where Threadripper shines, not in gaming. Cinebench score for a 12900K is around 1981, and a 3960X is 1296. That's a huge performance gap, and only wider with the 13900.

Sure. And I use my system for photo and video editing, which is why I have the collection of parts I have and where I regularly want 24c/48t for the work I'm doing. But if Intel is putting 350W desktop CPUs on the market, I have to ask what for? Gaming doesn't need or justify that except for the most dick-measuring of benchmarks and most truly compute-heavy tasks are better off being done by a GPU or spread across many CPU cores rather than one or two performance cores. These things seem more like an excuse to waste electricity for bragging rights.

It's apparently NVIDIA native.
