NVIDIA’s next-gen Lovelace flagship has been reportedly spotted for the first time (courtesy of Greymon55). Featuring a triple fan cooler and a rather massive black heatsink, this could be the first Founders Edition (Reference) variant to come with more than two fans. The GeForce RTX 4090 Ti leveraging the fully enabled AD102 die is said to pack as many as 18,432 cores across 84 SMs and 48GB of 24Gbps GDDR6X memory.
The GPU will be paired with a 384-bit bus alongside a 96MB L2 cache, much like AMD’s Infinity Cache. This results in a single-precision throughput of nearly 100 TFLOPs and a TGP of 600 to 800W.

Originally, the RTX 4090 Ti was set to land towards the end of the Lovelace cycle but the latest rumors indicate that it is being prepped for an earlier launch, possibly as early as H1 2023. Personally, this heatsink looks like a prototype, and although the final SKU might feature three fans, the shroud and colors are likely going to be flashier.
