NVIDIA GeForce RTX 30 “GA102” Series PCB to feature ‘over 20 chokes’

Please note that this post is tagged as a rumor.

A new rumor has surfaced in regard to the upcoming GeForce RTX 30 PCB design.

RTX 3080(Ti): up to 20 densely packed capacitors?

Irregular PCB design for the upcoming GeForce RTX 3080 Founders Edition

NVIDIA is about to set the bar even higher; by introducing even more complex power delivery for the upcoming GA102 GPU board design, new rumors suggest.

The company has been upgrading its power delivery design for high-end models with each generation. The last 2 generations have seen a noticeable upgrade in a number of components and their quality. While the number of power stages is often meaningless to casual gamers, those seeking higher clocks are definitely going appreciate the current stability.

A new rumor suggests that the PCB might see yet another upgrade with up to 20 chokes. We are not sure which model the leaker referring to though. The same PCB is expected to be available for RTX TITAN Ampere, RTX 3080 Ti (3090) and RTX 3080. All these cards are supposedly using the same PG133 board design. There is allegedly also PG132, which was designed for board partners, but unlike the 133 it features a regular rectangular shape.

The leaked RTX 3080 PCB revealed that the company has been working on a complex irregular shaped board design with two fans pointing in different directions. Such a design required the components to be squeezed around a V-shaped fan hole. As a result, this has increased the complexity and component density on the graphics card.


Come on, over 20 chokes……


extreme compact

1. So-called 24/20GB 384/320-bit Only right on one point.
1) 3090 is 24GB this is fine, pushing up KatCorgi also confirmed
(2) then in order to high-speed video memory is not used 16Gbit particles, this is a double-sided 2Rx32 specifications, positive and negative a total of 24 stars!
2, 3080 and 3090, although using the same core, but 3080 seems to be to re-sample the PCB, rather than 3090 cut two particles made out of the
3, by the way, 3090 is an interesting arrangement of this particle, there is a particle put to the bottom
4, this time the public version of the power supply luxury is unimaginable, or cooling pressure is unimaginable…. NVIDIA SMX kind of card power supply density you all understand, this time is bound to do a dense, a cylinder solid capacitors are not, instead of all the chip capacitors / tantalum capacitors.
5, is not a shaped PCB I do not know anyway, but NV this PCB layout merit to be honest!

It’s better than Mrs. Su’s HBM card.
