At this point, it is pretty much confirmed that RTX 4060Ti is coming out at the end of May. A leaked embargo document by Videocardz says that RTX 4060Ti confirms this. However, the release timeline for RTX 4060 was not known.
The bigger surprise is that RTX 4060Ti will have another variant with 16GB VRAM. According to the leaker @MEGAsizeGPU, the RTX -60 class will be RTX 4060Ti 8GB, RTX 4060Ti 16GB and RTX 4060 8GB. All these three will be announced in May but only RTX 4060Ti 8GB will be released at the time. The RTX 4060Ti 16GB VRAM and RTX 4060 will be available from July.
Beyond memory size, little is currently known regarding the differences between the RTX 4060 Ti’s 8 GB and 16 GB versions. 34 of the 36 streaming multiprocessors (SM) physically present on the 5 nm “AD106” silicon are rumoured to be included in the RTX 4060 Ti 8 GB, giving NVIDIA some potential leeway to enable a few additional shaders.
These 34 equate to 4,352 CUDA cores, but an AD106 with all of its cores unlocked has 4,608. The RTX 4060 is a very different SKU that is built on the most powerful “AD107” and has 30 SM or 3,840 CUDA cores. However, it should be feasible for certain RTX 4060 cards to be built on the AD106, which has been severely scaled back.
RTX 4060Ti with 16GB seems like an overkill and will most probably be priced $50-$100 higher than the “original” RTX 4060Ti with 8GB. This is going in the direction of the RTX 4080 12GB fiasco rather than giving the consumers what they want.
RTX 4050 was earlier reported to come out in June, but it seems like it has been pushed ahead to release later, most probably in Q3.
