Motherboard vendors have been sporadically announcing their new premium- and high-end motherboards based on the AMD X870E and AMD X870 desktop chipsets, however, we've had a hard time finding or ordering these online. It turns out that although AMD allowed its motherboard partners to tease or announce their products based on the new chipset models, their market availability is timed.

Apparently, you should be able to buy these motherboards starting September 30, 2024. In the run-up to their availability, various online retailers have put up these motherboards at fairly high prices. Motherboards based on the cheaper AMD X870 are typically priced above $250, while those based on the top X870E start around $325. It is widely rumored that the mid-range AMD B850 will launch early next year. Until then, you always have the option of older AMD B650 chipset motherboards. If you want to pair these with newer Ryzen 9000 series "Granite Ridge" processors, you can take advantage of the UEFI BIOS Flashback feature.

AMD has reportedly pushed the launch of mid-tier models from its AMD 800-series chipset to early 2025, reports ComputerBase.de. With the Ryzen 9000-series "Zen 5" processors already launched earlier this month, and compatible with existing AMD 600-series chipset motherboards with a BIOS update, motherboard vendors are leisurely announcing their motherboards based on the AMD X870E and AMD X870 chipsets. Motherboards based on both offer drop-in compatibility with Ryzen 9000-series processors, and introduce new connectivity features such as 40 Gbps USB4 and Wi-Fi 7.

The company probably wants the two to have some time in the Sun before they're joined by the more affordable B850, which gamers could be drawn to. The AMD B850 has mostly identical platform I/O to the AMD X870, except Gen 5 support for the PCI-Express x16 slot is optional (motherboard vendors can choose to wire this out as Gen 4). The 40 Gbps USB4 is also optional here. You still get CPU overclocking support. The B840 is an entry-level chipset that's being launched to probably phase out the A620 and A620A, since it features similar I/O features to the A620A, but will probably come with drop-in compatibility for 65 W Socket AM5 processors. A deferred launch of the mid-tier chipset isn't too off character for AMD. It launched its popular B450 and B550 chipsets several months after the X470 and X570, respectively.

Gigabyte's new Stealth series of motherboards has to date only had a single product, the Z690 Aorus Elite Stealth, but now, Gigabyte has added its first Stealth board for AMD CPUs. The B650E Aorus Stealth Ice not only has all of its connectors on the back of the board, but it also has a white/silver PCB with a similarly coloured front and back cover. Apart from the DIMM slots, all connectors are also in somewhat matching colours, although judging by the pictures, the colours don't quite match on all the connectors and slots. That aside, the B650E Aorus Stealth Ice is a pretty competent board, as long as you're not interested in adding anything more than a graphics card and some NVMe SSDs, as it has zero additional PCIe expansion slots. It's a rather bold move by Gigabyte, but at the same time, most gamers and consumers don't tend to add PCIe devices to their computers outside of additional storage these days.

Besides the PCIe 5.0 x16 slot, you get two M.2 sockets wired to the CPU, one PCIe 5.0—with its own, larger heatsink—and one PCIe 4.0, as well as a third PCIe 4.0 M.2 socket via the chipset. There's also support for four SATA 6 Gbps drives if more storage is needed. Gigabyte has also added an internal HDMI 1.4 port that's limited to 1080p30, which is intended to be used with Gigabyte's LCD Edge View display. Other connectivity on the back of the PCB includes a USB 3.2 Gen 2x2 (20 Gbps) port, a USB 3.2 (5 Gbps) pin-header as well as the usual USB 2.0, fan headers and LED headers that you'd expect from a modern motherboard. The VRM design is a 12+2+2 design with a 60 Amp DrMOS configuration for the 12+2 phases for the CPU and GPU.

AMD is debuting its Ryzen 9000 series "Granite Ridge" desktop processors powered by the "Zen 5" microarchitecture later this year. These chips are compatible with existing AMD 600-series chipset motherboards with a simple UEFI firmware update, but the company is also taking the opportunity to launch the AMD 800-series chipset family alongside these chips. The lineup will be led by the AMD X870E, followed by the X870. These two chipsets should launch immediately alongside the new processors, but will later be joined by the AMD B850 and B840. There's no entry-level chipset planned, the AMD A620 will continue to hold the fort for AMD here. There is an interesting new mix of product differentiation, according to a leaked GIGABYTE slide scored by VideoCardz.

If you recall, the X670E and X670 were differentiated by a lack of Gen 5 PCI-Express x16 PEG slots on the X670, which instead was limited to Gen 4 on the PEG slot. The X670 still had Gen 5 NVMe slots attached to the CPU, and had practically the same I/O features as the X670E, including the same counts of downstream PCIe Gen 4 general purpose lanes. Both the X670E and X670 are 2-chip solutions, in that the second chip is a connected to the general purpose PCIe lanes of the first chip, which in turn is connected to the processor. Things are going to change with the 800-series. The top-spec X870E will be a 2-chip solution, with PCIe Gen 4 general purpose lane counts resembling the X670E; but the X870 is a single-chip solution that more closely resembles the B650E in I/O. The X870 (non-E) now gives you Gen 5 PCI-Express x16 PEG, just like the X870E and the B650E, and at least one Gen 5 x4 NVMe slot attached to the CPU, but has fewer downstream Gen 4 general purpose PCIe lanes than the X670. Both the X870E and X870 assure USB4 connectivity, and support CPU overclocking. Things get very interesting in the mid-range.

AMD is readying the new 800-series motherboard chipset to launch alongside its next-generation Ryzen 9000 series "Granite Ridge" desktop processors that implement the "Zen 5" microarchitecture. The chipset family will be led by the AMD X870E, a successor to the current X670E. Since AMD isn't changing the CPU socket, and this is very much the same Socket AM5, the 800-series chipset will support not just "Granite Ridge" at launch, but also the Ryzen 7000 series "Raphael," and Ryzen 8000 series "Hawk Point." Moore's Law is Dead goes into the details of what sets the X870E apart from the current X670E, and it all has to do with USB4.

Apparently, motherboard manufacturers will be mandated to include 40 Gbps USB4 connectivity with AMD X870E, which essentially makes the chipset a 3-chip solution—two Promontory 21 bridge chips, and a discrete ASMedia ASM4242 USB4 host controller; although it's possible that AMD's QVL will allow other brands of USB4 controllers as they become available. The Ryzen 9000 series "Granite Ridge" are chiplet based processors just like the Ryzen 7000 "Raphael," and while the 4 nm "Zen 5" CCDs are new, the 6 nm client I/O die (cIOD) is largely carried over from "Raphael," with a few updates to its memory controller. DDR5-6400 will be the new AMD-recommended "sweetspot" speed; although AMD might get its motherboard vendors to support DDR5-8000 EXPO profiles with an FCLK of 2400 MHz, and a divider.
