A couple weeks ago we reported about the discovery of a new PS3 model with the code CECH-4306CH certified by the Ministry of Communications and Information Technology of the Republic of Indonesia. The Japanese version of that model, coded CECH-4301x (where the x is a placeholder for the hard disk size code) has been recently certified by the Federal Communications Commission, and the documentation provided brought the first differences under the spotlight.
Here’s the spec sheet of the new model:
The first apparent element when comparing the new model with the older CECH-4201x launched in June 2013 is that the functional stats (clock requency, operating temperatire, size, weight and power supply input/output) are the same. That’s not very surprising, considering that a change of the second digit of the numerical part of the model code indicates internal revisions, and not a full fledged redesign, which would lead to an incremental change of the first digit.
The first change is in the WLAN (the wi-fi, in layman terms) component of the console. The second antenna has been changed from a Planar Inverted-F Antenna (PIFA) to an Inverted-F Antenna (IFA). Interestingly, Sony seems to be moving to IFA antennas for its WLAN components through his whole range of consoles. The same change is found in the newly certified PS4 model and even in the DualShock 4. The reason is currently unknown.
The second change is in the antenna of the bluetooth component, which remains of the PIFA type, but its gain has been changed from a peak of 3.5 dBi to 4.5.
Interestingly enough, the new documentation also lists power supplies made by three different manufacturers: Sony itself, and Taiwan-based Chicony Electronics and Delta Electronics.
Of course we don’t know if there are further changes in the new model, as the FCC certifies only radio communication equipment, so other internal elements of the console aren’t covered by its documentation.
