AMD has confirmed that its next-gen RDNA Three graphics playing cards gained’t use the identical energy adapters employed with the Nvidia RTX 4090, which has hit the headlines not too long ago with some reviews of issues round melting (sure – very unhealthy information certainly).

For many who missed this, these are 12VHPWR energy adapters utilized by of us to attach the RTX 4090 16-pin cable (for ATX 3.0, the most recent PSUs) to an ATX 2.Zero energy provide (that the overwhelming majority of PC house owners nonetheless have).

This was confirmed by AMD’s Scott Herkelman, who tweeted in response to a remark from Kyle Bennett about Navi 31 graphics playing cards rumored to not be utilizing the 12VHPWR adapter (within the circumstances of each Staff Pink’s reference boards and third-party playing cards). Hat tip to VideoCardz (opens in new tab) for recognizing this, by the best way.

Herkelman makes it very clear that no upcoming RDNA Three graphics card will use the adapter, which principally would solely apply to the top-end fashions anyway, that are probably the most power-hungry ones after all. Navi 31 is the chip that shall be used to energy what’ll theoretically be the RX 7900 XT and maybe the 7800 XT, the primary two RDNA Three GPUs that shall be launched by AMD in accordance with the grapevine.

That very a lot stays to be confirmed, after all, however we do now know that they gained’t use the 12VHPWR adapter.

Evaluation: Successful the ability and effectivity battle

What we aren’t advised here’s what AMD will really use – presumably 2 x 8-pin or Three x 8-pin connectors for the flagship (possibly the previous for the 7800 XT, and the latter for the 7900 XT – however that’s simply pure guesswork).

Naturally, we don’t know the way a lot energy that RDNA Three graphics playing cards will chew via, however rumor has it that the GPUs will use significantly lower than Nvidia’s Lovelace vary, and positively the AMD flagship will are available at lower than the calls for of Nvidia’s RTX 4090. Even when wattages are going to be cranked up from AMD’s current-gen playing cards (Staff Pink has mentioned as a lot up to now, after all).

Having this adapter challenge confirmed has definitely induced a sigh of aid to ripple via GPU-related boards on-line, notably in mild of the melting cable incidents (two of them so far with the RTX 4090) talked about on the outset. Nvidia is investigating these occurrences, by the best way, and we’re hoping that quickly we’ll hear one thing extra concrete about precisely what’s happening with these reviews from affected 4090 house owners.

Equally, we’ll quickly know much more about RDNA Three graphics playing cards, as a result of as you may need seen, AMD is formally launching them – or no less than revealing the preliminary GPUs – at an occasion on November 3. Nevertheless, these merchandise could not go on sale till December, if the rumor mill is correct.

Regardless of the case, we’ve already been primed to anticipate a 50% improve in performance-per-watt for RDNA 3 (the identical generational leap made by RDNA 2, the truth is); that means how a lot when it comes to uncooked frames per second avid gamers shall be getting relative to energy utilization. And with energy invoice taking pictures up, that will develop into extra of a consideration, definitely for the budget-conscious.
