40nm RSX Allows for Lightest, Most Efficient PS3

By - Source: Tom's Hardware US | B 44 comments

PS3's RSX GPU Gets 40nm Die Shrink; Even Lighter.

As part of the usual improvements throughout the console life cycle, Sony has updated the design of its PS3 Slim.

The major change this time wasn't a new feature or a new form factor, but rather a die shrink for its Nvidia-designed RSX GPU. The chip has shrunk from 65nm to 40nm, resulting in a reduction in both weight, heat, and power consumption.

A teardown narrated by Japanese site PocketNews examines the power requirements and updated (and simplified) designs for the cooling system. Compared to the original launch console, the new 40nm RSX-packing model CECH-2100A has a heatsink and fan that weighs nearly half of that from the first PlayStation 3 design.

Perhaps equally remarkable is that the new model's cooler weighs significantly less than even the PS3 Slim model unveiled last fall. The latest simpler cooling hardware weighs 408g, while the PS3 Slim's one that launched last year weighs 545g.

Expectedly, the die shrink has reduced power consumption by around 15 percent – an improvement in all powered-states. When powered off, the console still draws 9W.

Check out PocketNews for all the pictures and translated details.

    The new chip also allows the engine to rev well past 8000rpm thanks to it's K20 technology.

    I honestly would have kept the old heatsink. You can never over cool it. And then even a dirty heatsink will still have the cooling needed.

    I was gonna pick up a slim for the blu ray player and FF7 and Tactics over the PSN. Does anyone know how to tell the diffrence?

    Got a scale handy :p

    Why would I care how much it weighs when for me a die shrink means better performance, or is this G80-G92 all over again?

    408 grams = 0.89948603 pounds? Is that really how light it is? Or did I miss something.

    They mean the heatsink itself. It sounds like they mean the system, but the linked website clearly shows its just the heatsink.

    good thing they added the new intake and headers for more performance from the rsx the chip really unlocks the potential in the k20 engine....

    In this case, it's more related to cost reduction. The chip could be actually more powerful (sometimes more powerful chips are cheaper to make), but it will more than likely run in practice close to the speed of the original model. Lower power requirements means less powerful of a PSU needed meaning Sony saves more cash. If it weighs less, it may mean that it would be cheaper to ship.

    Maybe a possible price drop to $249-279?

    I checked the link, thanks for that. They really worded that poorly. I was sitting there saying to myself "No way, what?" Lol... XD

    Oh don't remind me.. I got sucked in with the idea that my new 9800GTX would be much faster than my 8800gts..

    Oh and normally a die shrink in consoles would not result in more performance mostly because they still have to code the game for the older revisions.

    I'll bet it even runs Linux. Oh, wait...

    now if they could fuse PS2 support into that chip, it would be even better news :-)

    Its been 4 years...not really surprising that its possible. Why not make a ps4?

    Who would have thought back in 2005 that the G70 would be alive long enough to go from 110nm down all the way to 40nm. Then again 24 shader, 8 rop, and only 128 bit MCM package. If any thing besides ram that holds the PS3 back its the RSX while it would be nice to have all the SPEs enabled instead of one electrically dead and another reserved for OS but I can see the PS3 enjoying a few more years of new titles and apps. Linux is a requirement for longer life still but who knows they don't want us Geeks to be learning new things about the Cell or the US military using them for surveillance.

    So does this mean the next gen PS will weigh at 250g? ;)

    is nvidia getting smarter by shrinking they're kids or are they just selling clone stamped C grade material?

    With the improved Bose Audio system, higher lift cams and more compact block design the RSX improves fuel economy by fifteen percent whilst maintaining 210hp at the crank. Unfortunately, in the "reduce weight at all costs" phase, the RSX engineers reduced seating to two persons to save on new cooling requirements.
