At the 2019 Flash Memory Summit, Realtek announced a slew of new Flash memory controllers targeting a diversity of devices, spanning from USB flash drives to USB external SSDs, M.2/U.2 NVMe internal SSDs. Leading the pack is the RTS5771, the company's new flagship NVMe SSD controller that features a PCI-Express 4.0 x4 host interface, 8 NAND Flash channels with up to 1,200 MT/s speeds per channel, NVMe 1.3, and DRAM cache. This becomes the third PCIe gen 4.0-capable client-segment NVMe SSD controller after the Phison E16 and the Marvell 88SS132x.

The RTS5765DL is its cost-effective sibling, which has PCI-Express 3.0 x4 host interface, just 4 NAND Flash channels, and is DRAM-less, allowing manufacturers to design cost-effective SSDs. It still has 1,200 MT/s bandwidth per channel, so drives that implement it can offer sequential speeds similar to premium drives from the previous generation. The new RTL9210 is a bridge chip that converts USB 3.1 gen 2 (10 Gbps) to PCI-Express 3.0 x2, ideal for cost-effective external NVMe SSDs. The controller also features an integrated RGB LED logic, so drive designers can bling up their creations.

That's PCIe 3.0.
Yes the Shasta named one is. But scroll down a bit, they have got a PCIe 4.0 one for client and one for enterprise products.

Samsung also has their own pci-e 4.0 drives in work. PM1733 is enterprise drive coming shortly.
