New PS3 Model CECH-4301x Certified by the FCC; First Differences With Old Superslim Found

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.

    Guys, I know it’s off topic but… There is a rumour that The Last Guardian has been cancelled: the information comes from russian bloggers. Of course I don’t trust any rumours so let’s wait for Sony E3, only 2 days are left!

      I’ve seen it. It’s as flimsy as toilet paper 😀

      Which is why it’s not reported here.

      • cozomel

        Damn, then get some new toilet paper then cuz thats not good, lol. Hey Giuseppe, i havent been keeping up like i should what surprises do you think we’ll see from Sony at E3. I know you’re on top of this ish.

    • Lemondish

      It’s relayed by Russian bloggers, which is an important distinction. That’s right, two Russian bloggers have said that they heard that the Last Guardian has been canceled.

      That’s not newsworthy one bit.

    Will it have Full PS2 disc playback to??? GOD i have been dreaming about that for YEARS!!! 😀

    • crazyhunter

      Yes there is a model that can play ps2 games!!!!!!!!!!

    I mentioned this earlier… the ps4/vita bundle seems to me picture the controller with longer handles.. idk if this would be the new controller or not but its definitely worth taking a peek and seeing what ya think,,

    • Boerewors

      Great spot, or nice photoshopping 😉 They indeed look way longer. Although I Iike the DS4, it could still use some improvements. My hands are too big to hold it properly, although I’ve been told I’m holding it wrong (like I would hold my Xbox controller, which is a bad thing apparently).
      And for the “new” ps3: I recently saw pics of an odd looking ps4 and DS4. At first I thought the PS4 wad already being remodeled, when it hit me… It’s the PS3 and the DS3 which gets a ps4/ DS4 makeover! So the ps3 is redesigned to match the ps4s look, and rumour has it they are preparing quite a spectacular pricedrop, mainly to give Blu Ray one last boost, which isn’t the big financial succes Sony hoped for.

    Hoping for PS2 backwards compatibility.

    Can anyone clarify if the switch-over in wifi antennas is a good thing in anyway? I’m always interested in understanding tech better, so anyone with insight, pleases share =]

      Hopefully it’s a good thing. You will get a faster internal speed from your router to your PS3/4. This will increases the download speed from PSN. However if your internet at home is slow then this will hardly make a difference. I try to use ethernet on all my devices (PC/PS4) as it is so much faster.
