AMD “X670E”: An “extreme” chipset for Ryzen 7000 is said to be planned


After the first rumours, there are now more details about a possible X670E chipset for AMD's upcoming desktop processors, which will be launched as the Ryzen 7000 (“Raphael”) on the new socket AM5, circulate. The suffix “E” in the name of the chipset should therefore stand for “Extreme”.

X670E, X670 and B650 for Ryzen 7000


AMD will accompany the release of its Zen 4 CPUs with RNDA 2 GPU not only with an X670 and B650 but also with an X670E chipset at the top of the PCH portfolio. At the end of April, it was already leaked out that the X670 chipset could also use a so-called multi-chiplet design consisting of two chiplets.

How “extremely” the AMD X670E- Ultimate chipset remains unclear, but it is said to bring a guarantee for high-end motherboards that the X670 and B650 cannot offer.

X670E guarantees PCIe 5.0 for GPU and SSD

The X670E, which, like the X670, is to be composed of two chips of the type Promontory 21 from ASMedia, is to guarantee connectivity for graphics cards and SSDs via PCIe 5.0 on any AM5 mainboard, while these can therefore also be used on mainboards with X670 and B650 in combination or may only be offered with PCIe 4.0.

We can now tell you that the X670E will be a special SKU where the E stands for Extreme. Based on the information we've managed to source, it doesn't seem to differ from the X670 chipset in terms of functionality or features.

However, all X670E motherboards must offer PCIe 5.0 connectivity to both the GPU and the M.2 NVMe SSD slot or possibly slots, whereas X670 based motherboards can use PCIe 4.0 instead, if the motherboard makers decide to make a more cost efficient motherboard. The rumor of a dual-chipset setup are also true, with X670E and X670 boards featuring two Promontory 21 chipsets and the B650 boards featuring a single Promontory 21 chipset.


A few days ago, an “X670E” was publicly discussed for the first time, details are expected next Monday. AMD's CEO Lisa Su already tweeted a corresponding picture including Ryzen 7000 CPU, the recording for the keynote should already be finished.

The new AM5 platform for AMD Ryzen 7000 will only support DDR5. There had already been corresponding hints in advance, but in communities there was always hope that cheap DDR4 memory could also be used.

AMD Ryzen 7000 (“Raphael”)

  • Zen 4 is supposed to come in the summer
  • RAMP and EXPO are supposed to accelerate DDR5
  • Ryzen 7000 is said to have up to 256 RDNA-2 shaders
  • Socket AM5 with DDR5 and X670 with two chiplets
  • Zen 4 CPU with integrated RDNA 2 GPU
  • Ryzen 7000 in the BOINC database< /li>

By the end of the year at the latest, AMD Ryzen 7000 and the Core i 13000 series aka Intel Raptor Lake should have the next CPU duel Unsubscribe generation.
