AMD’s 7000-series GPUs may be its most power-hungry cards yet

Efficiency and power requirements for the upcoming Nvidia RTX 40-series and AMD Radeon 7000 ranges of GPUs have been constantly brought up in rumors surrounding these next-gen boards — and for good reason.

Speculation surrounding the wattage amount for Nvidia’s boards (ranging from 450 watts to an unprecedented 900 watts) has justifiably raised eyebrows, while reports regarding AMD’s Radeon 7000 cards point toward a more efficient powerhouse. But even Team Red has now admitted that we will indeed see a jump in power levels for its cards as well.

As reported by Tom’s Hardware and VideoCardz, the former’s interview with an AMD senior vice president, Sam Naffziger, revealed some interesting tidbits in regard to the power-consumption levels for the Radeon 7000 -series.

For reference, Naffziger is an extremely experienced product technology architect, who was on the AMD team responsible for the company’s chiplet architecture.

He emphasized that as its rivals boost the power consumption requirements for its GPUs, AMD will also follow suit in similar fashion.

“The demand for gaming and compute performance is, if anything, just accelerating, and at the same time, the underlying process technology is slowing down pretty dramatically — and the improvement rate.

So the power levels are just going to keep going up. Now, we’ve got a multiyear road map of very significant efficiency improvements to offset that curve, but the trend is there.

“Performance is king, but even if our designs are more power-efficient, that doesn’t mean you don’t push power levels up if the competition is doing the same thing. It’s just that they’ll have to push them a lot higher than we will.”

Either way, it’s no surprise that we’re in line for a sizable jump in power draw for the Radeon 7000-series — with a purported 130% boost in performance, the thermal design power (TDP) is naturally going to soar as well.

There have been a considerable amount of reports pointing toward how RTX 40-series cards will be among the most power-hungry boards in history. Certain models like the RTX 4090 are said to require 450 watts, while other cards could reach an unheard-of 900 watts.

In any case, regardless of what the actual power consumption level is for Radeon 7000 boards, it’s been heavily rumored that AMD’s cards will, at the very least, be a much more efficient offering compared to the RTX 40 series.

In fact, the company’s engineers are so confident in their upcoming GPUs that they reportedly believe that these cards will “demolish” Nvidia’s entire lineup in efficiency.

What do higher power consumption levels ultimately mean for consumers? Simply put, the lower the power draw, the less amount of electricity it will generate. You don’t want to be paying for a third of your power bill from just using your PC alone solely because of the GPUs in these systems.

AMD’s Radeon 7000 series is expected to become available starting in October 2022, while Nvidia’s RTX 40 lineup should see a similar launch period during the latter stages of this year.

AMD’s overheating GPUs might be worse off than we thought
AMD Radeon RX 7900 XTX hovers over a raging fire.

According to an in-depth analysis by an overclocking expert, the overheating issue that has been plaguing some AMD Radeon RX 7900 XTX graphics cards seems to be affected by the orientation of the card within the computer.

Popular overclocking expert Roman Hartung shared a video on his YouTube channel, der8auer, that delves into this thermal throttling issue, and he found some interesting results. If the RX 7900 XTX is installed with a vertical orientation, the graphics card seems to run 10 degrees to 15 degrees Celsius cooler than the same card laid horizontally.

Bad news: AMD may have launched RDNA 3 before it was quite ready

The new AMD Radeon RX 7900 XTX and RX 7900 XT are already here, but a new claim suggests that perhaps they shouldn't be, at least not just yet.

According to the claim, AMD has decided to ship the GPUs in an unfinished state, and not everything can be fixed by simply updating drivers. Did AMD rush to release the new graphics cards before they were ready?

What power supply do you need for the AMD Radeon RX 7900 XTX?

Upgrading your graphics card can sometimes mean upgrading your power supply too, especially if it's one of the latest generations of flagship cards, like the AMD Radeon RX 7900 XTX. If you want to make sure everything's smooth and stable, it's best to check whether your current PSU can handle the upgrades provided by AMD's new range of GPUs, dubbed RDNA 3 or Radeon RX 7000.

So far, the new GPU range only has two cards: the RX 7900 XTX and the 7900 XT. Out of those two, the RX 7900 XTX is the one that consumes the most power. Even then, it's still fairly conservative when compared to the Nvidia flagship, the RTX 4090. In Nvidia's case, the Founders Edition has a total board power (TBP) of 450 watts and calls for an 850-watt PSU. However, some of Nvidia's board partners that made custom versions of the GPU require a much beefier PSU, reaching as high as 1,200 watts.
