Already final week we had been capable of see the PCB of the RTX 3090 in an official video from NVIDIA, the place it detailed its new design method for its GeForce RTX 30 collection graphics playing cards. This PCB is particularly for the RTX 2090, because it contains a complete of 24 sockets for GDDR6X reminiscence die (12 within the again and 12 within the entrance), so it may well solely belong to this mannequin.
RTX 3090: Smaller PCB with 20 Phases
Although the pictures we’ve seen to date of the NVIDIA RTX 30 present us a reasonably large measurement (bigger, in reality, than present fashions), evidently this would be the case due to its large heatsink and never due to the PCB of the graphs is giant. Quite the opposite, the PCB has seen its measurement markedly lowered compared, but NVIDIA has noticeably improved its capabilities.
The PCB options 20 energy chokes, making it an much more ‘premium’ design than present technology top-of-the-line graphics. From what appears in response to its electrical design, the GPU works with 18 phases whereas the remaining two phases can be found to the 24 GB of GDDR6X graphics reminiscence.
Paying a bit of additional consideration to the PCB of this RTX 3090 we are able to glimpse the connection designs for the video outputs, the place we discover three ports DisplayPort 1.4a and a HDMI 2.1. Keep in thoughts that these video outputs are for NVIDIA’s Founders Edition model, however then assemblers will be capable to change this at will and, in reality, we’ve already seen some present two HDMI 2.1 ports and three DisplayPort 1.4a.
Additionally, the Founders Edition playing cards of the GeForce RTX 30 collection will function energy connectors Micro-Fit 3.0 12-pin. These connectors won’t require you to vary the facility provide, because the graphics will embody an adapter as anticipated to make use of two 8-pin PCI-Express connectors on this new kind of connector.
The location of this new 12-pin connector on the PCB can be noteworthy, and it’s as a result of it’s positioned in a vertical place and, judging from the PCB structure, it isn’t tough to see why NVIDIA has determined to modify between connector in these graphs. The PCB could be very compact as we talked about earlier than, they usually have needed to redesign the facility conduit and use this connector as a substitute of two 8-pin ones to save lots of area. However, as traditional this reference design that we’re will almost definitely be overtaken by the customized designs of the assemblers.
The quickest Ampere chart… and costly
As you realize for now we are able to solely speak about assumptions and leaks (though at present we’ll nearly definitely know extra official particulars), however in response to what we all know to date the RTX 3090 would be the quickest graphics of NVIDIA thus far. It has a GA102-300-A1 GPU, with 5248 CUDA cores in 82 SMs. In complete, it has 20% extra cores than the RTX 2080 Ti, and though there isn’t a leak for the time being to verify its working speeds, it isn’t tough to imagine that the efficiency might be significantly larger.
Of course, if the RTX 2080 Ti are already extraordinarily costly graphics and throughout the attain of only a few (even at present their worth is round 1,200 euros), these RTX 3090 of the brand new Ampere structure might be much more so. In the absence of NVIDIA confirming its ultimate worth, in concept they are going to be round 1,400 euros.
