The point was data pins. So that the new standard PSU's can communicate to the card how much power they can supply. Then on top of that someone figured that would it not be better if there was only a single cable.

Some optimistic engineer optimized it to the bone and it was decided that yep, it can handle 600W alright if the stars align just right and the user does not bend the cable in any way within the visual range of the card.

I'd expect consumer protection agencies getting involved and then proceed to tell to the industry consortium which is responsible for these power sockets that it is not OK at all for things to catch fire.

Meaning that after an investigation it is possible that regulators might withdraw CE and its US equivalent markings from any product having one of these sockets on them, making it illegal to sell or even import any of these into US / EU.

Fire hazard is a pretty damn serious issue.

As a short-term fix NVIDIA/AMD, etc would probably issue a driver/firmware update that limits the released cards to max ~400W. The connectors themselves might have to wait a few years until the next hardware gen to get improved somehow.

Too little pins, too many amps and almost no case in use has enough room above the card to leave 35 mm space from the connector until you bend the cable. The 4000 series are already pretty thicc then you plug in there a connector, that is itself some 10-15mm long, then you need 40 mm more plus whatever the bend takes as its not like these cables can be bent easily at sharp 90 degree angle.

I saw this at FIRA last week. Very impressive, 90% weed elimination. The two main problems are it is expensive and lasers are effective when plants are small and very little coverage by crop. Nexus Robotics had a mechanical weed picking robot that has a longer efficacy period. Carbon Robotics is about 1 million per robot Nexus about 50k per season. For the Nexus you might have to follow manually to get to 90+% elimination

>how many large farms do you think uses those?

Depends on the specific setup and weeds they're combating. They're actually quite popular for herbicides. Made up about half at every place I've worked in the past, but nowadays I can see them being used a lot more. That being said, simply being made/derived from plants doesn't make them safe for the environment though.

> No harsh bs chemical

There's a lot of "harsh bs chemicals" that are specifically derived from plants themselves, and don't do much/any long term damage. The issue is plants become resistant towards herbicides, meaning you have to have multiple methods that you cycle throughout seasons. I see no reason why the plants wouldn't adapt to this either.

If this actually works (not just in testing), and is cheaper than chemicals, I can see it being popular.

I don't even know what was wrong with the old pins.

Sure, you would need 4 of them but this leads to the questions why such a high power draw.

The 4090 at 70% of the power limit performance in games on avg 7% below the max power limit. They released a gpu that is stock already past the efficiency limit. Graphs clearly show that. That's usually the OC range. If you up the wattage from stock you gain like 2%. If you go past the efficiency you hit a wall where you need exponentially more power to increase the performance slightly.

It's a waste of energy, hands you just little performance with the risk of burning the power port and cable.

The only reason to do this is that the last few percent might give you the edge over the competition. Still we know if AMD beats them they come up with new gpus.

It's stupid. For casual users it should be right at the end of the efficiency range while past it should be a thing for people that are into OC. There are tons of people who don't touch a thing and run it stock. They won't and often don't even know about the way better efficiency if the simply lower a slider a little bit.

The positive for the consumer is that the coolers are made for the high tdp means if you lower it the gpu runs really cool comparable to undervolting 30 series gpus.
