The RTX 3090 Ti set to 300W: like an RTX 3080 Ti however with much less energy consumption
In transient: Power effectivity is just not the very first thing that involves thoughts when one thinks of the RTX 3090 Ti, but it appears undervolting the cardboard actually could make it much less power-hungry than a few of Nvidia’s and AMD’s greatest whereas sustaining a efficiency benefit.
Igor’s Lab performed a check on the RTX 3090 Ti that concerned undervolting the cardboard, which has a 450W energy consumption, right down to 300W. Igor achieves this by adjusting the ability restrict to 300W utilizing OC instrument MSI Afterburner and adjusting the VF curve. He duplicated the curve of the RTX A6000, which can also be slowed to 300W and options the identical GA102 die—although it makes use of GDDR6 as a substitute of GDDR6X reminiscence.
Igor examined the MSI Suprim X RTX 3090 Ti in opposition to the identical model of RTX 3080 10GB/12GB, RTX 3080 Ti, and RTX 3090 playing cards. He used MSI’S Gaming X variations of the AMD RX 6800 XT and RX 6900 XT.
Looking on the 4K benchmarks, we see that the usual RTX 3090 Ti manages 107.4 fps, dropping simply over ten fps to 96.3 fps at 300W.

The RTX 3090 Ti pulls a most of 314W within the checks, whereas the 3080 Ti reached 409W, but Igor concludes that the 2 playing cards are roughly equal in efficiency. The undervolted card manages to beat the Radeon RX 6900 XT (359W), RTX 3080 12GB (393W), RTX 3080 10GB (351W), and the Radeon 6800XT (319W).
Of course, that is only a demonstration of what is potential with the RTX 3090 Ti. The card prices round $2,000, whereas the RTX 3080 Ti is roughly $1,200+, and it may take a really very long time and a number of use to recoup the $800 distinction through energy saving. Still, it is actually an attention-grabbing experiment.
Make positive to take a look at our assessment of the RTX 3090 Ti, which we known as quick and dumb.
