NVIDIA won’t be refreshing its heatsink design this time around, according to sources familiar with the matter. Like the GPU die, however, it’ll be getting wider and fatter to accommodate the increased TDP and heat dissipation. According to @kopite7kimi, the GeForce RTX 4090 and the 4080 will look much like the RTX 3090 Ti, at least in terms of dimensions. We’re talking about a fat four-slot design aimed at cooling 600W SKUs and not burning down the system in the process.
No necessary now.
RTX 4090 looks like a RTX 3090 Ti, RTX 4080 does that too.

The GeForce RTX 4070, like the RTX 3070 Ti, will be a dual-slot design with a TGP of 350-400W. A bunch of renders of the supposed RTX 4090 Ti has also been shared by Moore’s Law is Dead. While it’s hard to ascertain the existence of the GPU, it’s safe to say that the RTX 4090/4080 will look somewhat similar:
The GeForce RTX 4080 and 4090 are said to come with a TGP of 450-600W, while the 4090 Ti may push it all the way to 800W but that’s debatable. This is despite being based on TSMC’s 5nm N5 node and one of the most advanced graphics architectures.
NVIDIA plans on launching the RTX 40 series GPUs in the last quarter of the year, starting with the RTX 4090 in October, 4080 in November, and finally the 4070 in December.
