The RTX 4090, which features NVIDIA’s newest Ada Lovelace architecture, can run at clock speeds far greater than earlier architectures. NVIDIA has shown the card operating at 2.85 GHz with ease, which was in its basic configuration. Gamers and overclockers can get much higher clocks with little effort, up to 3.0 GHz during stress testing with Kombustor or even 3.1 GHz during lighter workloads. However, 3.0 GHz seems to be a good speed for most high-end GPUs.
The screenshots shared on Bilibili indicate that the RTX 4090 can operate at either 3.0 GHz and 425.6W or 2.64 GHz and 615.8W. Both outcomes are exceptional for any GPU, but it has been shown that the RTX 4090 can achieve them. It appears that the leaker conducted both tests using MSI Kombustor. The 3.0 GHz clock was performed with the default test called “msi-01”, and 616W has a recorded workload called “Furmark-donut”. The latter is considerably more power-hungry. GPU temperature and memory hot spots were the only things not displayed; the leaker indicated that this was on purpose.
The NVIDIA GeForce RTX 4090 has a TDP of 450W by default, which is also the default setup for most custom models. However, most cards will also have “OC” or “Gaming” versions, with TDP rising well over 500W. In addition, GPUs such as the Founder Edition have a power restriction of up to 600W, which may explain the card utilized in this test.
