New Nvidia GeForce RTX 4080 and 4090 leaks are bad news for our energy bills

New leaks for the Nvidia GeForce RTX 4080 and 4090, Team Green’s next generation of GPUs using the Lovelace architecture, have emerged that suggest these high-end graphics cards could have worrying power demands.

As revealed by Igor’s Lab (opens in a new tab)An image of the supposed PCB (Printed Circuit Board) of the AD102 GPU that these cards will use has emerged, and it looks like these new cards could have a TDP (Thermal Design Power) of up to 600W.

That’s a huge amount of power and eclipses the 350W maximum TDP of the RTX 3090 – once considered a very power-hungry card itself – requires.

Analysis: high energy consumption = bad news

The Nvidia RTX 4080 and RTX 4090 will be cards aimed at enthusiasts, where performance is the most important aspect and power consumption and price don’t matter. But if these future GPUs really require more than 600W to run, that will have big implications for many people.

The obvious problem is that the more energy they need to operate, the more expensive they could be in the long run. Not only will there likely be a high upfront cost, but with our ever-increasing energy bills, using a power-hungry PC could have a noticeable financial impact, and one that many people may have to consider when upgrading or not. .

Power-hungry components also traditionally get very hot when in use, which means these newer GPUs will need heavy cooling solutions to keep them from overheating. That means you’ll probably need a large PC case, as coolers could take up quite a bit of space – and you’ll want to make sure there’s plenty of airflow.

It could also mean that PC gamers may need to replace their PSU (Power Supply Unit) as well, as anything below 1000W likely won’t be able to power those GPUs. and the rest of the PC. Replacing a power supply is an expensive and time-consuming upgrade.

All of which means that if this leak is correct, the RTX 4080 and RTX 4090 will have to be seriously impressive upgrades to justify the price and inconvenience of the upgrade. Worryingly, the new leak from Igor’s lab suggests that the 12 solder slots of GDDR6X memory will mean the RTX 4080 and RTX 4090 will have 12GB and 24GB configurations, the same as the RTX 3080 Ti and RTX 3090.

Although the amount of memory – and its type – is not the main thing when it comes to GPU performance, it certainly plays an important role. And again, if this is correct, it could mean that people will be disappointed with the minimal spec upgrade.
