Nvidia GeForce RTX 4090 FE PCB defined – News235

On Wednesday, Nvidia launched a few of the distinctive options of its new GeForce RTX 4090 graphics card in addition to the printed circuit board (PCB) design. With the intention to guarantee optimum energy provide to the GPU and maximise its overclocking potential, it seems that the enterprise solely reworked the cardboard’s voltage regulating module (VRM) by including a PID controller with a suggestions loop.

The GeForce RTX 4090 Founders Version graphics card from Nvidia is much like its predecessor when totally constructed as a result of it nonetheless has a sturdy dual-fan cooling system with a unibody design. Nonetheless, the brand new product has various noticeable exterior and, extra crucially, inner modifications.

The brand new GeForce RTX 4090 FE, like earlier generations of Founders Version graphics playing cards, utilises a extremely superior but small PCB with a triangular lower on its again that’s meant to extend the effectiveness of Nvidia’s circulation by means of thermal design.

The PCB comprises a single 12+4-pin 12VHPWR further PCIe Gen5 energy connector that may provide as much as 600W of energy to the element, whereas the GeForce RTX 4090 FE from Nvidia is barely able to drawing 450W on the manufacturing facility settings. The board additionally comprises a 20+3-phase VRM (20 phases for the GPU and three phases for reminiscence), which is a modest enchancment over the GeForce RTX 3090/3090 Ti FE’s 18+3-phase energy circuitry.

With the intention to reduce present peaks and valleys, Nvidia put in a PID controller with a suggestions loop, successfully regulating energy supply to its GeForce RTX 4090 Founders Version graphics card, in response to TechPowerUp. With out offering a precise quantity, Nvidia claims that their new VRM supplies a considerably sooner energy administration response time. For stability below heavy masses and overclocked situations, a dependable and clear energy provide is crucial. 

This operate, which the environmentally pleasant enterprise refers to as “energy transient administration,” could also be one of many methods it is ready to overclock the AD102 graphics processor to three GHz with out overvolting it or using aggressive cooling methods.

With the GeForce RTX 4090 FE, Nvidia not solely redesigned energy provide, but in addition improved the cooling system with bigger followers that may transfer as much as 20% extra air. The brand new GDDR6X reminiscence chips used on this card are additionally much less power-hungry. We will solely assume as to how the ability consumption of DRAMs with PAM-4 signalings was decreased, however we suggest that Micron makes these chips utilizing a thinner manufacturing technique, which naturally reduces their energy consumption. Moreover, with cooler reminiscence, the cooling system will be capable to overclock the GPU extra successfully.
