Despite NVIDIA's strict investigation, but in recent years, the sneaking of ampere game video card is still quite serious, and its credibility is relatively high. The first one is mainly high-end video card, which uses ga102 core, at least RTX 3090, RTX 3080 Ti, RTX 3080 video card. RTX 3090 will replace the former Titan video card.

In terms of specification, all three cards are based on the ga102 core of ampere architecture, and the new generation gddr6x is matched with display memory, which is respectively matched with 384-BIT 24GB, 352-bit 11gb and 320-bit 10GB, and the power consumption of the whole card is respectively 350W and 320W. 320W, the output interface has three displayports, one HDMI, and RTX 3090 also supports nvlink.


In addition, the heat sink of the RTX 30 series public founders edition graphics card will also be greatly changed, and the dual fans with positive and negative rotation will be used, which greatly improves the heat dissipation capacity,This also makes the radiator cost as much as 150 US dollars, about 1000 yuan, very expensive.

The reason why NVIDIA has changed the radiator greatly on the amp game card is that it is related to the power consumption. The performance of the new generation of video card has increased by 50%, and the power consumption has also increased,It is reported that the RTX 3090 graphics card is 350W, much higher than the current 250W.

But is that really the case? According to igorslab website, it may be a misunderstanding that the high power consumption of ampere high-end graphics card is high. This 350W power consumption is TGP power consumption, not TDP power consumption. TGP power consumption includes the power consumption of components on the whole PCB.


For this reason, igorslab calculated the components of 350W power consumption, among which 60W power consumption is needed for 24GB gddr6x video memory, and about 26W power consumption is needed for MOSFET and other power supply components used for GPU power supply, plus other power consumption, fan and PCB losses, the power consumption of GPU is restricted to 230W.

The power consumption of 230W GPU is not high. Don't forget that the TDP power consumption of RTX 2080ti is only 250W. In this way, the power consumption of flagship amp GPU is actually low. In addition, the performance increases by 50%, and the energy efficiency increases by at least 50%.
