Realtek to Join the PCIe 5.0 NVMe SSD Controller Race

Currently, only Phison offers widely available performance PCIe 5.0 NVMe controllers for consumer SSDs, although the competition is heating up and Chinese SSD controller makers MaxioTek and InnoGrit, as well as Taiwanese Silicon Motion either have or will be releasing competing controllers this year. However, it also looks like Taiwanese Realtek will be joining the fray, albeit a tad late, as their upcoming RTS5782 PCIe 5.0 NVMe controller, but the company didn’t reveal a release schedule. Although Realtek is known as a more budget friendly chipmaker, regardless of the product segment, the RTS5782 will be an 8-channel controller with support for 3600 MT/s NAND, and it will have a dedicated DRAM cache using either DDR4, LPDDR3, LPDDR4 or LPDDR4x memory. It’s said to deliver sequential read speeds of up to 14 GB/s and sequential write speeds of up to 12 GB/s, with random read and write IOPS hitting 2500K.

Realtek is also working on a pair of new DRAM-less models, the PCIe 4.0 RTS5776DL and the PCIe r5.0 RTS5781DL, both having support for 4-channel flash, but still supporting NAND speeds of up to 3600 MT/s. Engineering samples of the RTS5776DL are expected to be available before the end of this year, and it’s said to deliver sequential read and write speeds of up to 7400 MB/s and random read and write IOPS of 1200K. The RTS5781DL will enter the engineering sample stage in the beginning of 2025 and will up the sequential read and write performance to 10 GB/s and the random read and write IOPS to 1400K. In addition to the new NVMe controllers, Realtek also had its RTS5736DL on display at Computex, which the company claims is the world’s lowest power DRAM-less SATA SSD controller, that also supports size of up to 8 TB. Realtek claims the RTS5736DL is an ideal solution to pair with a USB 3.x bridge chip for external drives.
