More and more information about the GeForce RTX 40 video card appears on the Web.
According to all available data, the new cards will be very voracious. Different sources say different things, but in general, top cards are credited with TGP in the range of 450-600 watts. In order to convert the appropriate amount of energy, the new cards will need a very powerful power subsystem. According to recent reports, the AD102 GPU board will have a 28-phase power subsystem!
Higher 3D cards are expected to have either 12GB or 24GB of memory. That is, Nvidia can again make a conditional RTX 4090 Ti with 24 GB of memory, while the RTX 4090 and RTX 4080 will receive only 12 GB each.
Also, very interesting data concerns the not yet released GeForce RTX 3090 Ti. The source says that Nvidia needs this card as a testbed before the release of a new generation, as it will be able to test solutions associated with huge power consumption. Moreover, it is possible that the GA102 and AD102 GPUs will be pin compatible, which will allow video card manufacturers and Nvidia itself to adapt RTX 3090 Ti boards for RTX 4090 and RTX 4080 at minimal cost.
Huge heat dissipation is also expected to cause even Nvidia’s reference top-end adapters to take up three expansion slots, and cards from other manufacturers may be even thicker.
