On July 1, it was reported that Intel will release the next generation of high-performance desktop processors Arrow Lake-S later this year, switching to a new LGA1851 package, with a new 800 series chipset motherboard, and the flagship model is Z890.

Now netizens have exposed the architecture characteristics of the Arrow Lake-S processor and Z890 chipset, which seems to have not changed much compared to Z790, the most prominent thing is that the memory no longer supports DDR4, only DDR5.
However, it is not clear what the frequency support of DDR5 is, and it is believed that it will definitely be higher than the current DDR5-5600.
You must know that AMD's Ryzen 9000 has supported DDR5-6000 by default, with a maximum DDR5-6400 for 1:1 division, and a maximum of 8000MHz can be plugged in with four strips, and more than 9000MHz with only two plugged in.

In addition, the PCIe expansion lanes continue to improve, of which the PCIe 5.0 of the processor has been increased from 16 to 20, which can be used completely for graphics cards and SSDs at the same time, no longer need to be split, and there are 4 PCIe 4.0 lanes.
The chipset also supports 24 PCIe 4.0 strips, an increase of 4 strips, but no longer offers PCIe 3.0.
In other aspects, the new platform integrates a Thunderbolt 4 controller, supports two interfaces, and is compatible with HDMI 2.1 and DP 2.1.
There is still no native USB4 (after all, there is Thunderbolt 4), and it continues to support USB 3.2 20Gbps, USB 3.1 10Gbps, USB 3.0 5Gbps, as well as 10 Gigabit + 25 Gigabit Ethernet, Wi-Fi 7 wireless network.
