CECHJ - 40GB and CECHK - 80GB PS3 consoles must be 65nm RSX

Postby Anthony on Sun Aug 02, 2009 7:48 pm

I am submitting this post as I believe the information on the PS3Secrets blog on the size of graphics chip inside the 40GB CECHJ and CECHK is incorrect.

I own the CECHJ console and have took numerous watt readings and it runs with the same wattages as others have mentioned the CECHM - 65nm 80GB console runs at.

Same goes for the CECHK on my discussion thread someone took their wattages of this console and they are the same as mine too.

Here is the discussion thread where this has been established.

Could you consider correcting your info about these two consoles RSX being 65nm and not 90nm.

Also could I ask how you established the CECHJ - 40GB console was 90nm RSX as originally it was down as 65nm, did you measure the graphics chip (something I would not be willing to do with mine as its still under warranty).

Thanks
Anthony

Thanks for your input. It is appreciated. Sorry about the delay in approving and replying your post (I have quite many things occupying my time)

In regards to your measuring the wattage to obtain the RSX size, there is NO one-to-one correlation at this moment that states a specific wattage equals a specific size. In fact, a lot of the PS3 innards are still secret, and Sony is changing them constantly with each revision. The fan size, heat sink, consolidation of the chips, etc. Sometimes (like the PSP) firmware updates are done with specific measures to protect the security of the system, and no public notice is given on what was changed.

What the webpage PS3 Secrets aims to do is to uncover those secrets. Are there going to be mistakes at certain times? Yes. However, just like a scientific process, with time more and more truths are discovered when more and more people (like you) uncover different aspects of the system. However, your interpretation (one of many) is not as reliable as prying off the cover of the RSX and measuring the size of the chip. That is the only one-to-one correlation (scientific) at this moment that can prove once and for all the size of the RSX in a specific PS3. An even better one is for the scientists responsible for the RSX shrinkage to confirm it publicly (assuming he is not trying to dish out disinformation to confuse the competition).

I notice you have taken it quite personally (since you own a CECHJ) that your PS3 must have a smaller size RSX. Rest assured as more and more people get more and more intimate knowledge about the PS3, someone will finally uncover the truth. And when that happens, the PS3 Secrets page will reflect this truth. With time old thinkings (sun revolves around the earth) gets replaced with better ones (earth revolves around the sun) to even better (each object like the earth and sun revolves around larger gravity/masses around them). So perhaps you can provide a better source? Or you can prove the wattage for your PS3 has a direct linkage to a RSX size reduction (and not some other changes on the motherboard). Note that you may be right, and if you are, then you actually are siding with my original assumptions (before I changed them). Unfortunately, they had to be changed because I could only get confirmed source on the CECHL (a very recently released PS3 in Japan at that time I might add). It was also the ONLY one that was disassembled with PROOF that the RSX (cover lifted) is 65nm and confirmation that the RSX 65nm existed. The figures were changed because a German tech site retracted their claim of 65nm RSX in earlier PS3, and if they (a pretty reputable site) can't back up their claim, I don't think I can either (but the best I can do is back a disassembly and reputable Japanese reporter).

So the PS3 Secrets page is not much different from a scientific process (hypothesis and fact finding). As for the PS4 Secrets, if you look at the top of the page, it is stated that it can't be 100% correct because the PS4 is not released, and it is mostly a prediction and speculation, but a dynamic one that will get closer and closer to a real PS4 when it gets released. I've read your reply at the forum above, and feel sorry you feel so negative about a small section of the PS3 Secrets page. I hope you look on the bright side and see that you probably gained more personally (via knowledge or whatever) from that page than anguish that your specific PS3 model is not listed on that page with a smaller RSX.

This is a long post. I hope it provides answers to future people who want to know how the facts get put into the page. Like science, it is a dynamic page, and it gets updated with better facts as they are uncovered (or discovered). Maybe one day Sony will come out and reveal their secrets, until then this page provides a service for people who want to know the truth.

http://www.edepot.com/forums/viewtopic.php?f=9&t=1532 contains pics of the 65nm RSX (CECHL). Having said all that if someone has lifted the cover of the RSX on the CECHJ and CECHK (it is not a hard procedure, as it is easily lifted, unlike the CELL cover) and simply take a photo, it would provide proof that the first RSX was placed inside before the japanese CECHL.

As an update,

http://www.edepot.com/playstation3.html ... wer_Supply

now contains more information on power supplies in different models of the PS3. Unfortunately, newer models of the power supplies use different amps, which affects wattage used. Some PS3s with the same model number may use different power supplies, which affect the wattage also. In fact the weather may have a bigger effect on wattage than anything else, because the fan will kick in faster for those who live near the equator (hotter).

Also, take a look at:

http://www.edepot.com/playstation3.html#PS3_RSX_GPU

The RSX serial number between the CECHK and CECHL are different, and varies too widely compared to CECHL and CECH-20xx (off by only the suffix letter so they use the same 65nm process). This may not indicate the CECHK is using 90nm, but it does show that CECHK and CECHL are using different RSX chips.
