NVIDIA RTX 4090 May Yet Get a TGP of 600W with Over 2x More Performance than the RTX 3090, RTX 4070 May Leverage GDDR6X Memory

NVIDIA’s next-gen RTX 40 series graphics cards are hotly anticipated for launch later this year. Based on TSMC’s 4nm process and densely packed dies, rumors have suggested performance gains ranging from 1.75x to 2.5x. The TGB (total graphics power) has been the more widely discussed subject on the topic. Earlier, there were claims suggesting a peak power draw of as much as 900W, but these were eventually debunked by popular insiders.

According to @kopite7kimi, the GeForce RTX 4080 and 4090 will both leverage the PG139 boards suggesting pin compatibility. The former is known as the SKU360 while the latter is the SKU 330. The source has already suggested that the RTX 4090 can have a TGP of 450W, but there’s still a chance that it may be pushed to 600W to reach final performance estimates.

The AD102 die powering the RTX 4090 is reportedly still being optimized. Kimi states that it’ll easily surpass the GA102 (Ampere) by at least 2x, and probably more as it’s fine-tuned. Going back to the TGP, the RTX 4080 can also be pushed to 450W and the RTX 4070 to 400W if paired with GDDR6X memory. If true, this will be the first time a budget video card is paired with it.

Igor’s info seems to confirm the delay in the RTX 40 series launch. The RTX 4090 is now expected to launch in late September or October, followed by the RTX 4080 and the RTX 4070 through consecutive months.

Kimi believes an 800W RTX Titan is also a possibility with crazy levels of raster and ray-tracing performance.
