CCR2004-1G-2XS-PCIe is a “router in the form of a network card” released by Mikrotik in early 2022, which is a two-in-one product of a network card and a router.
Regarding the CPU model of CCR2004-1G-2XS-PCIe, Mikrotik’s brochure says AL32400, which is consistent with the models on other CCR2004 series routers. However, the product page on the official website reads AL52400, which is confusing, and the CPU model is not displayed in RouterOS.
The one I ordered just arrived this week. I took it apart and found out that it is indeed AL32400, with a suffix of 1700, which should indicate the 1.7GHz frequency version. Consistent with other CCR2004 series routers, this CPU is also used in a QNAP NAS. Its core specification is 4-core A57 (ARM Cortex-A57 1.7GHz x4). A57 is the previous generation architecture of A72. Unlike A53 and A55, A57 is a high-performance core belonging to the same A7x series. Therefore, it can be considered that the CPU performance of AL32400 is similar to The BCM2711 of the Raspberry Pi 4 is similar, the latter is a 4-core A72, 1.5GHz or 1.8GHz (the new version of arm_boost), and the performance is relatively good for routers.
The following is a detailed disassembly diagram (click the picture to view the original size)
It is said to be dismantling, but in fact this is a PCIe card. After removing the PCIe baffle, unscrew the 5 screws on the back and remove the heat sink to reveal the whole picture:
back:
CPU, or SOC:
Remove the cooling fan, its specification is 12v 0.13A 4 wires, diameter 44mm, hole spacing 39mm, thickness about 1cm:
PCB overview:
It can be seen that its layout is very similar to that of an ordinary high-speed network card. The difference is that the central chip is a SoC instead of a network card chip, and there is memory above it. The memory size is 4GB, but the number of memory particles is 5. Yes there is ECC.
The model and analysis of other accessory chips will be updated here in the future
Regarding its actual use experience, I will publish a new article in the follow-up.
