The release dates of the next-gen GeForce RTX 40 series graphics cards have yet again churned out of the rumor mill. The top-end RTX 4090 will be the first to launch somewhere between early to mid-October with an announcement slated for next Monday. Based on the AD102 core, it will feature a partially disabled die with 16,384 FP32 cores and 24GB of GDDR6X memory across a 384-bit bus and 72MB of L2 cache.
The RTX 4080, on the other hand, will come in two variants: One with 12GB of GDDR6X memory and the other with 16GB. The former will utilize a 10-layer PCB and the latter will have a 12-layer PCB. Both will leverage the AD103 die alongside a 256-bit bus and 64MB of L2 cache.
The 12GB SKU is expected to have a TGP of 285W and the 16GB part will raise it all the way to 340W. As such, the performance delta between them could very well be over 20%. This is notably larger than the delta between the two variants of the RTX 3080, pretty much putting the latter on a separate price/performance slab.

- NVIDIA GeForce RTX 4060: January (CES 2023)
The RTX 4060 is planned for an early 2023 release/unveil. It’ll offer a more conservative uplift than its brethren but should be one of the more popular parts, nonetheless. You can read more about the RTX 40 series GPUs below:
