Rumor mill: In line with business assets, Nvidia has shared its reference forums for the flagship RTX 4000-series GPUs, which could be referred to as the RTX 4080, 4080 Ti, 4090, or 4090 Ti, with its OEM companions. It hasn’t delivered the GPUs themselves but, however the forums are geared to eat 600W of energy.
A number of leakers with excellent monitor data have not too long ago stated that they expect the RTX 4080 or 4090 to have a 600W TBP (general board energy). A better-end type, both the RTX 4090 Ti or some particular version card, may eat over 800W. However they have additionally hooked up a number of disclaimers to these numbers, noting that it is too early for actual main points to had been finalized.
Igor’s Lab studies that Nvidia has instructed OEMs to check the reference forums used to lend a hand them design their PCBs and coolers on the complete 600W. No longer each and every 4080 or 4090 will essentially eat 600W out of the field, however no less than some will turbo or overclock into that energy bracket.
Igor’s Lab gained an image of a reference board from a Chinese language OEM and showed its authenticity with two different assets (above). One standout function used to be the twelve slots for reminiscence modules, which point out that the GPU can have both 12 GB or 24 GB of GDDR6X reminiscence, possibly the latter.
It additionally had an excellent 24 voltage converters, up from 20 at the Founder’s Version RTX 3090 PCB (shared between the GPU and reminiscence). It used UPI Semi’s UP9512 controllers able to 8 stages, so 3 controllers in step with section.
All the ones converters and modules are fed through one 12VHPWR connector, often referred to as the PCIe 5.0 energy plug, which will ship 600W by myself. Igor’s Lab notes that OEMs are designing PCBs that use the entire 600W, however, as discussed, that is a ceiling, now not a median. Each and every 12VHPWR connector will include an adaptor with 4 6+2 pin Molex plugs, even if maximum energy provides do not include that many cables.
The insiders be expecting Nvidia to reuse the 3090’s three-slot air cooler for the 4080 and 4090. In the meantime, producers are reportedly getting ready 3.5-slot air coolers and taking into consideration water-cooled answers very similar to what AMD used for the RX 6900 XT LC.
In a possible first, the 3090 Ti and 4080 are allegedly pin-compatible, which means they are able to use the similar PCB designs. Igor’s Lab speculates that OEMs could be the use of the 3090 Ti to check their 4080 coolers and PCBs. So the 3090 Ti and the 4080 may percentage portions.
On the very least, the 3090 Ti is the trial run for the 12VHPWR connector. Rumors point out that the 3090 Ti will eat 400-500W relying at the type, a variety that appears loopy in comparison to the RTX 3000-series however tame in comparison to the rumored figures for the RTX 4080 and 4090.
