If you blinked you would have missed a certain unboxing video, as it was posted before the NDA on the GTX 1660 Ti expired. However, a few sites managed to get some screengrabs before the video was taken down, so we now know a bit more about the card once thought to be mythical.

Specifically, it was an MSI GeForce GTX 1660 TI Gaming X that was revealed to the world and while there were no benchmarks, there now seems to be physical proof that this card exists. It sports a single 8pin PCIe power connector, three DisplayPort 1.4 and a single HDMI 2.0b outputs and not a bit of RTX branding. Instead it contains 1,536 Turing Shaders and a 12 nm process "TU116" chip hidden under the Twin Frozr 7 cooler. The outputs tell us this particular card is not compatible with VirtualLink.
For AMD fans, The Inquirer is reporting that 7nm Ryzen 3 desktop CPUs and Navi GPUs should be announced on 7 July at Computex. We should also see the new X570 chipset, though the rumour is that the current generation of motherboards will support the new Ryzen series with a BIOS update. Sadly, Navi is likely to only be announced as it is likely the release will be delayed until October, though like everything else in this post that is purely speculation based on a variety of sources and may not be accurate.
One thing we do know is that the new flagship Ryzen 9 3800X will have two eight core Zen 2 dies, offering a total of 16 cores and 32 threads. The base clock should be 3.9GHz with a top speed of 4.7GHZ, and a TDP of 125W.
