Rumor mill: Nvidia may be preparing a monstrous GPU that will require two PCIe 5.0 power connectors; possibly a Titan RTX successor based on Ada Lovelace’s architecture. At least so far, rumors are pointing to much more normal specs for the rest of the RTX 4000 series, so there’s still hope that gamers won’t need a small powerhouse to power Team Green’s next-gen GPUs.

With RTX 3090 Ti graphics cards, Nvidia has made the most of the performance of the Ampere architecture by raising the power limit to 450W. Independent testing also disclosed the card is surprisingly efficient when the power limit is set to the more reasonable 300 watts.

Ada Lovelace’s next generation architecture is still shrouded in mystery, but that hasn’t stopped the rumor mill from hinting at what to expect. According to the infamous Twitter leaker @kopite7kimiNvidia may be cooking up a monstrous GPU that will outshine the RTX 3090 Ti in many ways.

In particular, the company is said to be testing a full-fledged AD102 GPU with at least 900W TGP, higher clock speeds, and 48GB of GDDR6X memory. The test board is reported to come with two 16-pin PCIe 5.0 power connectors, unlike the RTX 3090 Ti which comes with a single connector.

This could be the first Nvidia Titan product in years, or simply an indication that transient loads and power spikes on engineering samples are too much to handle with just a single 16-pin power connector. Leaked Layouts for reference RTX 4000 series boards include only one of these and are otherwise very similar to the Ampere reference designs. The worst scenario is the one where it’s ridiculous April fool concept materializes into a real product a year ago.

Kopite7kimi says the rest of the RTX 4000 line will have the same TGP ratings as their Ampere predecessors. But more importantly, the RTX 4080 could have 16GB of GDDR6X memory, while the RTX 4070 could have 12GB of GDDR6. These are only preliminary specs and are therefore subject to change in the future, but it would be a welcome improvement over the RTX 3000 series.

The GeForce RTX 4000 line is expected to launch this fall and could be the first Nvidia-designed GPU with the help of AI. Meanwhile, power supply manufacturers are gearing up for a new generation of power-hungry graphics cards. The only model we have seen in stock is Gigabyte GP-UD1000GM at Newegg for $189.99.
