Sustainability: Is the power consumption of new hardware still up to date?

admin

The new CPU and GPU generations from AMD, Intel and Nvidia are about to be launched or have already been presented and once again entice with even more clock, performance and FPS. But are 450 watts for a GeForce RTX 4090, 251 watts for a Core i9-13900K or 230 watts for a Ryzen 9 7950X still up to date?

Power supplies with 750 watts+ are on the rise

Almost 60 percent of the approximately 9,800 participants in ComputerBase's 2021 hardware and software survey stated in December last year that they were using a power supply unit with more than 500 watts, and almost a quarter even used a PSU with 750 watts and more. A look at the current hardware reveals that this will not change any time soon, at least if high-end components are to be used.

How strong is your power supply?
  • Up to 300 watts – 3.7%, 3.2%, 1.9%, 1.8% 2.1%
  • Above 300 to 500 watts – 35.7%, 30.6%, 24.2%, 19.9% ​​15.5%
  • Over 500 to 750 watts – 51.4%, 56.7%, 62.7%, 62.4% 58.3%
  • More than 750 Watts – 9.2%, 9.5%, 11.2%, 15.9% 24.1%

9,797 participants  +  158 abstentions  •  Final result

A very clear trend has been discernible since 2019, especially for power supplies with 750 watts and more, which has intensified again significantly in 2020 and especially in 2021. Gamers who want to switch to the new CPU generations Intel Raptor Lake or AMD Raphael or the latest graphics cards from the Nvidia Ada Lovelace and AMD RDNA 3 series this year sometimes have no other choice.

The power consumption keeps increasing

TDP, TBP, TGP, PBP, MTP and PPT are increasing again across the board, which is a quick look at the top models of the new and previous generation of the CPUs and GPUs.

Intel Core i-12900K → Intel Core i9-13900K
  • 125 Watt PBT (TDP /PL1) → 150 watts PBT (TDP/PL1)
  • 241 watts MTP (PL2) → 253 watts MTP (PL2)
AMD Ryzen 9 5950X → AMD Ryzen 9 7950X
  • 105 watts TDP → 170 watts TDP
  • 142 watts PPT → 230 watts PPT
Nvidia GeForce RTX 3090 → Nvidia GeForce RTX 4090
  • 350 ​​Watt TDP/TGP → 450 Watt TDP/TGP

The upcoming AMD Radeon RX 7000 based on the RDNA 3 architecture and the Navi 31 graphics processor are said to have a TDP/TGP of up to 350 watts. So the latest CPUs and GPUs can absorb more energy across the board, but do you still think this is up-to-date in times of ecological change and global energy crises?

TDP, TBP, TGP, PBP, MTP and PPT keep increasing

While the editors have already taken a look into the future with the Nvidia GeForce RTX 3090 Ti (test) and its enormous TDP of 450 watts+, showing that cooling the Nvidia GeForce RTX 4000 and AMD Radeon RX 7000 will not be easy, it will be Future scenarios will soon become reality for gamers. But is that still up-to-date these days and is it still justifiable for a hobby?

Is the increasing power consumption still up-to-date today?

how do you see it? More and more performance and the associated ever-increasing power consumption and waste heat at any price, or would you prefer strict limits, a reversal along the way and TDP values ​​falling again in the future?

CPUs with up to 250 watts+ and GPUs with 600 watts+

While desktop CPUs by the end of 2022, thanks to generously chosen TDP, PBP, MTP and PPT limits and OC features, can go up to 250 watts and more, the new 12VHPWR connector and the standards ATX 3.0 and ATX12VO 2.0 will allow up to 660 watts for upcoming custom designs of the GeForce RTX 4000 series.

Where do you draw the limit for the TDP of your CPU and GPU?

Even gamers don't always have to go straight to the spearhead of the latest CPU and GPU generation and can therefore also use hardware with lower power consumption.

Where do you personally draw from the limit for the TDP of your CPU and graphics card?

New CPU + new graphics card = new power supply

Even if Nvidia advertises that the energy efficiency of the GeForce RTX 4000 should be significantly higher than that of Ampere and AMD will also be able to make progress with the Radeon RX 7000 series and the RDNA 3 architecture compared to RDNA 2, a system with a new CPU and GPU will consume even more at peak times than in the previous generation.

Are you considering upgrading your hardware Consideration?

For many users, upgrading to Intel Raptor Lake or AMD Raphael in combination with Nvidia Ada Lovelace or AMD Navi 31 is also tantamount to buying a new power supply, which is why buying a new one should be considered all the better.

How do ComputerBase readers see the current situation? Will you upgrade to Intel Core i-13000, AMD Ryzen 7000, Nvidia GeForce RTX 4000 and AMD Radeon RX 7000?

Are you planning to upgrade your system?
