NVIDIA Ada flagship RTX 4090 to be announced mid-July

Kopite7kimi has new information on the flagship NVIDIA Ada graphics card.

NVIDIA GeForce RTX 4090 is to feature 126 Streaming Multiprocessors, which gives 16128 CUDA cores in total. That’s a lot less than previously rumored 140-142. As a reminder, the full AD102 GPU features 144, which means 2304 cores will be disabled on the flagship RTX 40 GPU. One should note that RTX 4090 Ti is more than likely to follow later, featuring even more cores.

Furthermore, kopite7kimi provided a new estimate on RTX4090’s TDP. It is no longer 600W, but 450W instead. That said, the 600W spec might refer to the 4090 Ti model, while 450W is exactly the same metric as RTX 3090 Ti, which was considered a ‘test vehicle’ for AD102 GPU. The RTX 3090, to which RTX 4090 is being compared to as ‘twice as fast’ has a TDP of 350W.

Kopite reiterated his claims on RTX 4090 memory specs. The card will feature 24 GB of GDDR6X memory clocked at 21 Gbps. This means 384-bit memory bus and over 1 TB/s bandwidth.

According to the leaker, GeForce RTX 40 series are to launch in mid-July. This is a confirmation to what Kopite posted yesterday and has left some of our readers wondering what exactly did he mean.

It is very likely that in the first wave, RTX 40 series are to include RTX 4090, 4080 and 4070 SKUs. Just remember that those are still rumored specs, and clearly there is a lot changing each week. Of course, we will do our best to confirm those specs as quickly as possible.
