Nvidia might be doing one thing very other with the RTX 5090 Founders Version in comparison to its earlier flagship GPU, and the end result may simply be a thinner graphics card – which might indubitably be a just right factor, given how cumbersome high-end fashions have were given at the moment.
VideoCardz picked up on a couple of items of hypothesis right here, the primary of which is that the video reminiscence configuration of the 5090 can be very other, as claimed via Panzerlied, a leaker on Chiphell (and we’d sprinkle a variety of seasoning in this).
We’re instructed the VRAM (rumored to be GDDR7) can be extra densely packed to facilitate having extra reminiscence – as much as 16 chips in truth (fairly than 12), connected by the use of a 512-bit bus as prior to now rumored.
Panzerlied additional reckons that Nvidia will cut up the RTX 5090 into 3 PCBs or revealed circuit forums.
Any other leaker on X (previously Twitter), Kopite7kimi chimes in right here, backing up this idea, and increasing on it to say that there’ll be one major board (with the core parts, GPU and reminiscence modules), an I/O board (inputs and outputs, show controllers) and a separate board for the PCIe slot. (Thoughts you, the latter could also be tiny – as Kopite7kimi issues out, it would possibly not also be regarded as as a 3rd PCB).
Kopite7kimi additionally elaborates at the GPU, which can it sounds as if be a monolithic chip, however consisting of 2 hooked up GPU clusters. On the other hand, there are not any actual main points on precisely how this may paintings, or if it will have any damaging ramifications for PC gaming – if the RTX 5090 has been designed for extra heavyweight paintings, this is (although you’d hope this wouldn’t be the case).
As you’ll see, the design is rather other, if these kinds of rumors pan out. Definitely there’s been rather a little bit of chatter already that Nvidia will run with a 512-bit reminiscence bus (and GDDR7) at the RTX 5090, and so the brand new hypothesis is smart in that mild.
In idea, with 16 reminiscence modules, if Nvidia sticks to the 2GB dimension, the RTX 5090 may run with 32GB of VRAM if it has the entire supplement of chips. Despite the fact that simply because there’s house for 16 modules doesn’t imply Workforce Inexperienced has to populate all of them.
As to the brand new PCB design, that can have primary implications for cooling. Panzerlied even hinted that Nvidia might be having a look at a twin slot cooling resolution for the RTX 5090, and that may be a significant trade. Briefly, the Blackwell flagship is usually a reasonably trimmer graphics card than the RTX 4090, and that’d be nice information for the ones short of to suit the next-gen GPU in a extra modest PC case.
How the theory of a slimmer RTX 5090 marries with no matter Nvidia’s plans are to ramp up efficiency, via rather some margin possibly – and what kind of wattage the Blackwell best canine may chug down – that we don’t know, however colour us intrigued at this newest twist within the thread of rumors.
The most obvious concern is the possible price of the RTX 5090, after all, if it pushes to 32GB of GDDR7 VRAM and springs with a large efficiency soar as prior to now rumored – however extra eyes could also be at the RTX 5080, thoughts, which would possibly neatly arrive first in any case.
