New RAM in 5G 60GB iPod doubles memory, improves performance

imageThanks to a report by an iLounge reader, additional details on internal differences between the 30GB and 60GB iPods have been discovered. As initially shown through a diagnostic test of the new iPod, the 60GB model actually contains twice as much SDRAM - 64 Megabytes rather than 32 Megabytes. SDRAM typically serves as a buffer for audio and video clips, and additional memory can reduce the number of times an iPod’s hard drive is accessed, thereby further improving battery life.

imageLike the 32MB component, the 64MB chip is a Samsung part, here labeled K4M51163PC. Previous teardowns of the new iPod have not revealed this difference in components, as they have focused on the less expensive 30GB iPod.

imageIn combination with the 60GB’s new hard drive, which is shown to be a Toshiba MK6008GAH, and the unit’s battery (additional pictures of which are shown at Read More below), the additional memory helps the larger iPod to provide nearly six hours of tested audio run time over the smaller one, over two more hours of photo slideshows, more than one hour of additional on-screen video and over two extra hours of on-TV video. As noted in our comprehensive review, this is the first time that component differences between full-sized iPods have been used to create battery performance distinctions between models.

It’s GOOD that something other than HD storage capacity justifies the $100 difference in price between the 30GB and 60GB 5Gs.

Duh!
I predicted this last month because video requires more RAM, and 32 more MB of RAM is much cheaper than a hard drive that can be spun for more hours. It’s just logical. It’s not a suprise.

so what’s making the 60 thicker?  is it the hard drive, the battery, or both?  i’m sure i could find the answer some place, but i’m not going to right at this moment.

This may be off-topic, but if this new 60GB HD is a single platter, could it possibly be retrofitted into a 20GB-sized 4G iPod? It would make for a pretty slim and fairly cheap 60GB colour. Then again, the 60GB 5G is already thinner than the old 20GB-sized 4G.

The 60GB 5G is a dual platter HD and is the reason behind the thickness.

I’m a little confused, so does this mean that the extra battery life for the 60GB is due only to the 64MB of RAM vs. 32MB in the 30GB, or is the battery capacity also higher in the 60GB as initially thought?

Box, the 60 Gig HD in the iPod is 2 30 gig platters, so I dunno if it would fit inside the 20 gig… besides it would be kinda expensive so you might as well just buy a new iPod.

LukeA,

As wise as you think your prediction may have been, the “logic” doesn’t hold up since only the 60GB unit has the upgrade in RAM. Last time I checked both units do video.

My question is, would the additional memory make any difference to audio? I have no interest in video, but I do listen to a lot of audio books. Would the additional memory result generally in the drive having to spin less often without regard to what you were listening to (or watching?)

Pru: The harddrive starts every time you’ve listened through the audio temporarily stored on the RAM. So yes, the 60GB version should start it’s harddrive twice as less as the 30GB.

Also, twice ### less as the older iPods that also had 32 MB RAM, or the old iPod photos that had as little as 15 MB RAM.

Longer battery life comes from not only larger cache memory but also due to a larger battery due to the extra space provided since the case had to be larger for the bigger HDD.

That’s great, but the real question is, will it help the ipod to play an album all the way through without pausing between songs?  I have a 3G iPod, and this problem frustrates me to no end.

After reading this I returned my 30 GB iPod. I wrote about it on my site

No it will not make your songs play with out pause.  The cache has nothing to do witht that.  It has to do with Apples iPod software.

I bought a refurbished 40 GB from “The Store”. Anyone know which battery and what RAM it has?

Go 4 a Rio Karma if u want gapless playback and a superior audio quality too smile

> and a superior audio quality too

In what way is it superior?  From what I can find online, the iPod has a better S/N ratio.  The iPod (3G) been praised by Stereophile magazine for its fine audio performance.

Does the Karma have better frequency response linearity?  Is the THD lower?  Does it suffer from less TIM (Transient InterModulation) distortion?  Is the CODEC in the Karma superior.  Any web pages with specifications to support your claim would be apprecieated.
