Has there been a GPU era with such fiercely debated and rumoured specs as Nvidia’s RTX 40-series (opens in new tab)? I might say no, there hasn’t been. The upcoming lineup of graphics playing cards has shapeshifted far too many instances to rely over the previous 12 months. Nevertheless, with a possible launch window arising quick, we’re starting to see these playing cards’ closing kind—and there might be just a few completely different reminiscence configurations on the way in which.
We’re anticipating the RTX 4090 to guide the cost for the RTX 40-series, which is more likely to function 24GB of GDDR6X reminiscence as commonplace. That is not notably groundbreaking info as the present era RTX 3090/Ti additionally include as a lot.
Nevertheless, it is the RTX 4080 (opens in new tab) that might be a extra fascinating sight at its launch, although when which may come just isn’t fully clear. In keeping with leaker MEGAsizeGPU (opens in new tab) (by way of Videocardz (opens in new tab)), the place we might anticipate a single graphics card, we could discover two. The RTX 4080 is rumoured to reach with two completely different reminiscence configurations: both 12GB GDDR6X or 16GB GDDR6X.
Much more stunning is that these are stated to be essentially completely different graphics playing cards. The 16GB variant is reported to be utilizing a 12-layer PCB and the 12GB variant a 10-layer PCB. And each are stated to be arriving on the similar time.
Nvidia has provided such a cut up previously, although arguably the place it made extra sense within the extra entry-level market with the GTX 1060 6GB/3GB. On the greater finish of the efficiency spectrum, you’d suspect Nvidia to be somewhat extra certain of what is required of its high-end playing cards.
Although competitors will do issues to a graphics card firm, and it would not be fully in contrast to Nvidia to drift the thought of a number of reminiscence configurations and energy limits to make sure that it has all bases coated. AMD is coming in scorching with its RDNA 3 GPUs (opens in new tab) this 12 months, and Nvidia might be eager to see it has a solution to the RX 7000-series at each efficiency degree.

Nvidia just isn’t afraid of testing the waters with a number of reminiscence configurations for its GPUs after which ditching them at a second’s discover. Keep in mind what number of RTX 3080/Ti reminiscence configurations (opens in new tab) have been rumoured earlier than and even after its launch? It was rather a lot, and I heard from one GPU producer on the time of that they have been excruciatingly near finalising their very own design for one in every of these unreleased configurations earlier than it was canned.
We did find yourself seeing one such reminiscence configuration later within the RTX 3080’s life with the 12GB variant (opens in new tab), so such a launch for the RTX 40-series can be completely potential.
I might say the possibilities of these two RTX 4080 variants coming to the market at launch are about pretty much as good as some other rumoured RTX 40-series specification seeing the sunshine of day. Which is to say: we will have to attend and see.
We should not have to attend too lengthy for at the very least some point out of the next-generation GeForce GPUs, nonetheless—Nvidia’s CEO Jensen Huang is internet hosting the keynote of the corporate’s September GTC convention and the next-gen has already been tipped to make an look (opens in new tab) at that occasion.
