Some alleged specifications for the first Nvidia GeForce RTX 40 series graphics cards have surfaced online. origin, MEGA Size GPU (opens in new tab), today provided more details about the RTX 4090 reference design. But the biggest surprise was his claim that two of his RTX 4080 reference designs are brewing in Jensen Huang’s green cauldron. Before we go any further, please remember that this rumor may or may not be accurate.Add a pinch of salt to the soup.
Some believe that Nvidia’s Ada Lovelace architecture GPUs for consumers could (officially) hit the general public sometime this month. But first, it’s likely to start with high-end launches and releases, much like the Ampere generation. So it comes as no surprise that the first credible leak of tech specs that emerged via the Twitterverse, other social media, and tech forums involved purported products like the GeForce RTX 4090 and RTX 4080. Not worth it.
MEGAsizeGPU’s claims about the RTX 4090 are pretty simple. According to him, the RTX 4090 is said to feature 24GB of his GDDR6 and a reference design PCB consisting of 14 layers. The Nvidia RTX 3090 Ti FE board featured a 12-layer design he to overview the PCB layer specifications. Still, the most demanding top-end models (such as the K|NGP|N edition) come with a 14-layer PCB to facilitate greater power concentration.
Ada Lovelace’s specs tweet is edgy when it comes to the RTX 4080. MEGAsizeGPU claims that the pipeline already has two “completely different” designs he says. 12GB model with 10 layers PCB and 16GB model with 12 layers PCB. Both use GDDR6X like the RTX 4090. Nvidia has put out a different SKU only (or mostly) in memory quotas from the previous generation, but it might be more logical if this lower spec GPU is his RTX 4070 (Ti). MEGAsizeGPU later added that the 12GB sample has a 192-bit memory interface. It’s too different to market as an RTX 4080, so following the theory that the weakest GPU is the RTX 4070 fits better with previous reports.
If you’re worried that one of the first high-end RTX 40 cards to launch could feature a 192-bit memory interface, just like the previous generation 060 tier cards, the frequently updated Nvidia Ada Lovelace Check out all the features. So, speaking of the memory bus, Nvidia has started using a massive L2 cache on his RTX 40 series cards.
