Nvidia’s RTX 4080 & 4070 Power is OUT OF CONTROL!

[Gav]

Ok, so first of all, I want to acknowledge that this is my second video in 24 hours, Go check out the other here, I'm sorry, but I saw this info at 2 AM and had to make a video about it. So, Let’s get started with Nvidia, With the release of the RTX 3050 back at CES it looks like Nvidia has completed their GPU lineup for the RTX 3000 series. And with that, it's time to turn our attention to the RTX 4000 series.

So let’s recap what we have real quick. This week, we learned that Ada Lovelace, that’s the architecture for the next-gen graphics, Well it would be based on TSMC’s 4nm process. A process more advanced than what AMD will use for their RDNA 3 graphics. RDNA 3 will be based on TSMC’s 5 and 6nm process nodes.

Something else that has been floating around is the specs of RTX 4000. Specifically, the specs for the highest-end RTX 4090. It would sport the AD102 chip with up to 18 432 Cuda cores. I say up to because it's likely to not use 100% of the chip. Also, since its board design is compatible with the 3090ti, the RTX 4090 could sport up to 24GB of GDDR6X memory. The speed of the memory is faster but we’ll get back to that in a moment.

And with all of those specs comes a HUGE total graphics power draw or TGP of 600W. Oh, and the card would apparently still use the PCIe Gen 4 interface instead of the newer PCIe Gen 5, but that’s not an issue, Gen 4 has enough bandwidth as it is.

So what’s new? Well, legendary leaker, Kopite7Kimi got us some of the specs for the more reasonable RTX 4080 and 4070. As well as a monster that is apparently roaming Nvidia’s test chambers, but we’ll get to that in a moment.

20A circuits are about to go mainstream!

I knew this AX1600i would be useful again after SLi went tits up

Think of all those people who've asked about what power supply to buy. I mean, I guess it's time to up the recommendation heh. Another serious problem is the power draw at the wall. You get 1500w @15amps, and most of the plugs we use in house are shared circuits. The new question on Reddit is: my breaker keeps popping with my 4080ti howdo I fix this.... {Add thousands of responses here}

I know a sparky friend would say you really shouldn't run a sustained 15A load on a 15A breaker and should aim closer to 12A.

Anyways when I had an overclocked 1100T, 3 1080p monitors, two 6990's using the alternate bios + overclock on top of that I could trip the overdraw on my UPS. The next step up was to go to a 20A circuit and a UPS meant for a 20A circuit as there wasn't really any larger 15A models. It isn't that bad when you know an electrician at a minimum you likely need a 20A arc fault breaker if the plug is in a place like a den/bedroom, wiring and an outlet.

Arc faults at the time were a bit more expensive than they are now.

Most older homes only have 10amps or 1200w. AFAIK, only in newer code are the outlets rated to 15amp. That is unless they are in the kitchen.

If your breakers keeps popping then you need to ensure that the circuit is not being overloaded. Plain and simple. One other thing to look at is if the breaker itself is outdated or worn out.

ITs not too bad though. Usually in a room the outlets on different walls run on different circuits, albeit shared with those in another room, so you could balance the load a bit by running a cord to be used on the monitors, etc.

Even so this is getting out of hand with the amount of power needed these days.

My PC use has been decreasing, so unless something changes in life I won't be going for anything this expensive/power hungry. I just want the market to go back to competitive mid-range price wars.

How much $ / hour to game on a highly OC'd system..... who would have thought...but we also know there will be a few that will try 4090Ti SLi just to benchmark.....hello 2000w .....crazy !!!

For sure....see so many questionable psu threads with 3080Ti / 3090Ti already.........you know even psu's you think would likely be fine, but have some sort of inherent issue causing power spikes and killing cards.

Although I know its not a big deal as little gains but PCI-E 5.0 would have been a nice touch on the 40 series, even just to stay inline with current Z690.
