Still no pics? Artist renderings?

 

Are there two R4000's or are they just listing the single R4000 as both the CPU and the "Media Engine"? If it's two then that's pretty impressive...wouldn't that be double the PSone?

 

If they can price it right Gameboy is history. Then again, those Gamecube discs would fit in a portable player very nicely...and the Gamecube formfactor could be viewed as an initial manufacturing step toward a future handheld version (the price point is almost low enough to add a screen and additional costs of shrinking the unit a bit further).

And the PowerPC G3 and ATi Mobile GPUs are both very good at power managment.

Interesting...this thing might match (or better) the PS2 in most respects. I looked up some console specs and the PSP seems to have more in common with the PS2 than the PSone.

 

PSone

 

Main Memory: 2MB

Graphics memory: 1MB

CPU: R3000A

CPU Clock: 33.8 Mhz

 

 

PS2

 

Main Memory: 32MB

Graphics memory: 4MB

CPU: Emotion Engine (Modified R4000)

CPU Clock: 300 Mhz

 

 

PSP

 

Main Memory: 8MB

Graphics memory: 2MB

CPU: R4000

CPU Clock: 333 Mhz

 

The RAM does suck but the CPU is no slouch. And if there are really two R4000's in there...whoa! Drop some more RAM in this puppy! (though I doubt such a small screen really requires much RAM)

Specs talk the talk, but whether they walk the walk is a whole other kettle of fish. I'm not saying that the PSP won't possibly be good, there's little history of Sony doing things half-assed, but I don't think we should be slashing off the GBA's market share just yet. Let's actually see it and see it run something. And have a price point.

Ask a minidisc user about how a minidisc player/recorder uploads to a PC. (Hint: it doesn't, or at least only in real-time recording into your PC's line-in jack).

 

I think that when it comes to rights-management in particular, Sony The Electronics Company is more than willing to sell cripplewear to protect Sony The Publisher.
