NVIDIA RTX 4090 Ti Specs Leaked: 18,176 FP32 Cores, 48GB GDDR6X Memory and 800W Max Power

The specifications of NVIDIA’s full-fat AD102 die have been finalized, painting a pretty impressive picture of the RTX 4090 Ti which it will supposedly power. Well-reputed tipster @kopite7kimi has shared the board details of the PG137-SKU0 which will be paired with the AD102-450-A1 die (almost fully enabled). The fastest next-gen RTX graphics card will sport 18,176 FP32 cores paired with a whopping 48GB of GDDR6X memory via a 384-bit bus. The GPU core will hover between 2. (martinwater.com) 5GHz and 3GHz, depending on the cooling solution and workload while the memory chips will run at 24Gbps.

The total board power of this monster graphics card will peak at 800W. Compared to the RTX 4090, we’re looking at 11% more cores, twice as much memory, and a total board power of 800W. The RTX 4090 Ti should also feature the entire 96MB L2 cache block and boast a single-precision performance of 100 TFLOPs or more. Other than these two, the RTX 4080 Ti will also leverage the AD102 die.

The launch dates of the RTX 40 series lineup are a bit murky. Most sources believe that the RTX 4090 will be the only Lovelace GPU to hit retail this year. The RTX 4080 should land sometime in early 2023 (possibly CES 2023) alongside the RTX 4070, followed by the RTX 4060 in mid or late 2023.
