Back in July 2019, when AMD unveiled its X570 chipset for its Ryzen processors, it captivated enthusiasts and PC users as the first desktop chipset to feature PCIe 4.0. This brought many vendors wondering how to keep the chipset cool, and all but one (GIGABYTE X570 Aorus Xtreme) came with some form of active cooling. Fast forward to 2021 and the latest iteration of new models dubbed X570S does away with the chipset fan altogether. In lieu of this, ASRock has announced the new PG Riptide series with both an X570S and B550 model designed for gamers.

Starting with the more premium of the two, the ASRock X570S PG Riptide has dual PCIe 4.0 x4 M.2 (one with SATA support) and six SATA ports with support for RAID 0, 1, and 10 arrays. There are a total of three full-length PCIe 4.0 slots that can operate at x16/x0/+x4 and x8/x8/+4, with three PCIe 4.0 x1 slots sandwiched in between. Other connectivity includes a front panel USB 3.2 G2 Type-C header, two USB 3.2 G1 Type-A headers (four ports), and two USB 2.0 headers (four ports).

Aesthetics on both models are practically identical, with the X570S featuring a larger square chipset heatsink, with the chipset heatsink on the B550 resemblant of a shield. The ASRock B550 PG Riptide has three full-length PCIe slots, with the top slot operating at PCIe 4.0 x16 and the other two operating at PCIe 3.0 x4/x1, with three PCIe 3.0 x1 slots. Regarding storage, the B550 model has one PCIe 4.0 x4 M.2 slot, one PCIe 3.0 x4/SATA slot, and six SATA ports with support for RAID 0, 1, and 10 arrays.

The ASRock X570S PG Riptide supports DDR4-5000, while the B550 PG Riptide supports up to DDR4-4933 out of the box. Both have four memory slots with support for up to 128 GB of capacity. Both models are also advertised to feature a 10-phase power delivery with Dr. MOS power stages. Both models also come supplied with ASRock's patent-pending VGA holder.

The ASRock X570S PG Riptide has one USB 3.2 G2 Type-C, one USB 3.2 G2 Type-A, four USB 3.2 G1 Type-A, and two USB 2.0 ports on the rear panel. In contrast, the B550 PG Riptide includes the same but with two additional USB 3.2 G1 Type-A ports. Both rear panels include a Killer E3100G 2.5 GbE controller, with space through an M.2 Key-E slot for users to add a Wi-Fi module, while both also use a Realtek ALC897 HD audio codec which adds five 3.5 mm audio jacks and a S/PDIF optical output. There's one HDMI 2.1 video output and a PS/2 keyboard and mouse combo port on both models, while the X570S includes a small BIOS flashback button.

At the time of writing, ASRock hasn't said when the new PG Series X570S and B550 will be available or how much either board will cost.

    Hmm, I were kinda hoping that the refreshed boards would bring refreshed audio solutions, akin to the Z590 boards, and not the ALC897. :P

    Then again this is ASRock and clearly not the high end offerings.

    What a joke. 897 audoi on a mid range or higher board in 2021???

    So, for a third year in a row we will be on X570? I was thinking it is time for an update by now.
  • meacupla - Thursday, June 3, 2021 - link

    okay, so what updated features would you want on it?

    DDR5 support is coming with a new "AM5" LGA socket

    I must confess, I'm used to reading about Intel's new chipsets which seem to come every year.

    That being said, I thought that they would optimize the design for lower power usage at the very least. It is said that the x570 chipset is always running at maximum power draw even when not in use.

    It should be more efficient. its how they get rid of the fan.
  • Wereweeb - Thursday, June 3, 2021 - link

    What for?
  • ZoZo - Friday, June 4, 2021 - link

    USB4 maybe?
  • DigitalFreak - Friday, June 4, 2021 - link

    Nah, none of that will come until Zen 4 / x670, unless someone uses a 3rd party controller.

    Would you rather they release new chipsets without any significant changes every year like Intel does? Intel Z170 to Z490 generations are all basically the same with only a few electrical changes to prevent you using the newer chips on older boards.
