Sony: PSP Go's 480MHz clock speed reference was for USB, not CPU

We posted a news over the weekend about an FCC report that indicates that the upcoming PSP Go has a potential to max out its internal processor at 480MHz compared to the existing models that can only clock at 333MHz. Well it doesn't.


Engadget Japan contacted Sony Computer Entertainment to clarify the issue and they said that the maximum clock frequency mentioned in the report is for the USB device, not the CPU speed. So I guess the PSP Go will still clock at the usual speed as the other PSP siblings at 333MHz. Oh well.

whats up with the funny lookin psp go in the pic?

» yea

thats not the right pic for a GO

Yes it is a PSP Go. Someone forgot to do their homework!

QJ.NET FAIL

» lol

it's not QJ.net...

it's just the stupid info leaking around the internet.

and it's probably a typo 480MHz on a USB?? doesn't make any sense. whereas, if it's 480Mbp/s, it'll totally make sense since it's the speed of a USB 2.0 ROFL. i think sony or whoever submitted the form failed... or maybe i'm just wrong about the typo thingy. haha

» Well..

If they are transferring one bit per clock cycle then they would need a 480 MHz clock in order to transfer 480MBits/s, right?

» Yup

It's Cartman-shaped

» jax not really

remember the psp's proccesor works differnetly to a computer cpu as it can accive more per clock cycle than a standerd pc cpu

so it stands to reason that it is just an updated verson of the same cpu in current psp's but justs loads faster with the same slock speed (but dont quote me on it)

» bummer

i was really hoping it was a 480mhz cpu

Hah, oh well.

If I got one as a freebie I'd be happy with it, but for now my PSP-2000 is perfect for my needs.

by oblivion40 - 2009-07-06 11:39
» Rawr!

I wish that it was 480mhz, but i will probably get one as my psp2000's screen just broke and it was trashed anyway, so i'll just get a go instead, may be buyin my m8s fat for homebrew needs so ill be sorted in every aspect ^________^

by CityNightRush117 - 2009-07-06 12:19
» hmm

If you look at the variations of Mhz that a CFW PSP can run, then the pattern would raise it to 444Mhz, so I'm not sure why 480Mhz would be mentioned >.>

» damn

I *****ing knew that it was for something else, sony isn't that *****ing stupid to break backwards compatibility in the same generation.

by GreySoul - 2009-07-06 14:08
» Wrong

"Maximum clock frequency: 480MHz" ...what that is in any way related to the USB 2.0 480Mbps?? I think Sony is denying again untill official...

by genesiscopy - 2009-07-06 19:51
» well...

in layman terms the 480 MHz does implicitly implies the baudrate of 480 Mbps, but not necessarily implies bitrate of said rate. It all comes down to the types of signaling (multi-level etc) and the symbol rate as the ones used in the hardware. In digital systems, this may be determined by the rs232 (or any of the variants) baudrate. On the other hand it is quite possible to impy that the core cpu has the speed as the transfer speed, though in some cases the transfer speed may exceeds core cpu speeds (maybe via PISO at the rs232 interface).

» shanky what the hell?

I believe we're talking about the USB, not the CPU.. read the article, ok?

by JaXeRiR - 2009-07-06 21:38
» Right

Like I already commented..



If they are transferring one bit per clock cycle then they would need a 480 MHz clock in order to transfer 480MBits/s.. at least that's how I would imagine it works.
