Linksys WRT54G version difference

WRT 54g. This should be
The earliest specification in the route is good, but the hardware version has been updated many times.
(Novice) Note that the hardware configuration may vary depending on the version number, including the PCB sub-shapes.
V1.0: this is the earliest release. The following CPU model is configured: Broadcom 4710 @ 125 MHz flash = 4 m, Ram = 16 m wireless network card uses the minipci card of the Broadcom Chip
V1.1, in addition to the use of Broadcom integrated for wireless modules, and the addition of the JTAG interface, basically no other difference;
V2.0: In V1.1, the CPU is changed to broadcom4712 @ MHz, and the Board has a serial port and a JTAG interface;
V2.2, vswitch chip changed from adm6996l to bcm5325 in V2.0, no other difference;
V3.0, with the same configuration as v2.2;
V3.1, CPU clock speed changed to 216 MHz, and other versions are the same as V3.0;
In v4.0, the CPU is switched to broadcom5352 @ 200 MHz] 5352 @ 200 MHz. The CPU is integrated with the switch chip, which saves the dedicated switch chip, and the remaining are the same as V3.0;
V5.0 and v6.0, flash changed to 2 m, Ram changed to 8 m, and other versions were the same as V3.0; (Note that flash and RAM are both small, which is equivalent to configuration downgrade );
In v7.0, the CPU and wireless modules are different from those in 6.0. The CPU does not contain the switch chip. In addition, an adm6996 is installed, and the wireless module uses the atheros.

-------------------------
WRT54G-CN
This model is not found on Linksys's International website. It is only seen on the Chinese website. From the suffix, it is estimated that it is a model specifically released for the Chinese market. (This version may be available outside China, but the model numbers are different)
There is a saying that the WRT54G-CN is the V4 version of WRT54G.
However, I found many websites that did not find flash and ram of this model, as well as the introduction of CPU.
I also heard a saying that this configuration is made of CPU MHz, flash2m, and ram8m.

In addition, v2.2 and v2 are different.
Version 2.2 uses DDR dual-channel memory, which is twice faster than the original SDR single-channel memory.
The switch chip is broadcom5352.
There is another difference in the specific chip number, although they are all broadcom4712, the actual clock speed of Version 2.2 is 216 m

The following is a comparison of the performance and test of the ultimate version of WRT54G2, the second kill WRT54G/GS Series.

The earliest WRT54G V1 V1.1 is not recommended because the CPU is too slow

WRT54G V1.1 Rom 4 mb ram 16 mb cpu 125 MHz Routing System Linux Max brush DD-WRT STD Version tomato wayos
The following is the recommended WRT54G version.

Wrt54gs v7.0 and v7.2 hardware are Rom 2 mb ram 16 mb cpu 240 MHz Routing System VxWorks top can only brush DD-WRT micro version can not brush tomato wayos and other software

The WRT54G2 version is not recommended.
WRT54G2 Rom 2 mb ram 16 MB routing system before upgrading VxWorks can only brush DD-WRT micro version not brush tomato wayos and other software
