PSP Go processor more than 40% faster than original

njr - 174 days 3 hours ago

333 mhz on the PSP would chew up the battery fast, I wonder what the battery life would be like if this one is kept at 480 mhz.

The battery time will be the same as the original PSP.

I doubt it'll do 720p (not enough bandwidth, even with 480MHz). But more pixels might be nice. Or more polys and such. Maybe they can do that dynamically in combination with a new SDK ? That way games could do use the faster CPU (and GPU? - I think they all run the same clock, no?) and scale down transparently. Must be a reason why they put a 480Mhz clock in there. Otherwise they would just have made the chip smaller and use less power.

Having 111 extra mhz was able to produce games like GoW: COO, I cant imagine what another 147 would do. Interesting if true.

I remember having a hack for GTA: LCS that let you change the PSP's processor speed to 333mhz. The game ran SOOO MUCH smoother. But at the cost of the batterly life. You would lose 50% in about an hour. But it was fun!

On a more serious note; i wonder if this means there will be PSP GO only games, that use the slightly faster processor.
Or if games will have graphical options that are turned either on or off depending on which PSP you have. Like on the PSP GO of a certain game, textures would be a bit higher quality, and more particle effects and higher overall detail. But still won't change the overall gameplay.

there would probably be the same difference anyway, due to you waitng for the load times on the old PSP and the shortened battery life on the GO.

because its not like their will be psp go only games made to take advantage of the extra power.

Well it makes the price a bit more justified now but in the current economic climate it's still too expensive.

No, all PSPs can do 333MHz. The earlier ones were forced down to 222 or so. Firmware 3.5 enabled 333MHz on all models later. They might have needed more test cycles for the fast mode before they could enable that.

Ju is right. Besides, it's been over 4 years since the PSP has been first release. You can say the same about Nintendo DS except they kind of screw the old and new owners. The old have no camera and larger screen but the new lacks the gba slot for games like guitar hero.

So what you're really trying to say is, it's only bad because its Sony.

In other news, my first gen 360 lacks the quiet experience others have with their newer models. I never asked for a jet engine sounding fan MS.

GOW:COO was the first game to take advantage of the processor's unlocked speed of 333mhz BTW.

Any places in crash mode where it slowed down go crazy fast (the speed it was meant to be at).

Hm, but that CPU is a custom build MIPS core just for the PSP. If they were only after the power efficiency, they would simply have speced it with 333MHz. Fact is, that little thing yields at 480MHz. Maybe its just that nobody can build slower parts any more or it would not cost anything extra. But the spec sheet shows 480MHz, guess there's a clock in there running that, too (even if underclocked to begin with). At some point this could be enabled by SW (that's speculation).

Gamecube:

485Mhz Processor
162MHz GPU clock
43MB total RAM:
- 24MB System
- 16MB Sound and DVD drive buffer
- 3MB 1T-SRAM --> 1MB texture buffer, 2MB frame buffer

--------------------------

PSP-3000

333MHz (480MHz PSPGo) CPU x2(Main CPU + Second CPU block with media decoding hardware and programmable DSP)
64MB Main RAM
4MB Embedded DRAM ---> 2MB for GPU, 2MB for Media Engine (2nd CPU)
166MHz GPU clock

The big difference between the gamecube and the PSPGo would be the cache sizes for the CPU.

GameCube:

64 KiB L1 cache (32 KiB I/32 KiB D). 8-way associative. 256 KiB on-die L2 cache. 2-way associative

PSP:

16 KiB of two-way set associative instruction cache and data cache

BUT, the fact that there's two processors in the PSP definitely helps it out in comparison, especially since 480MHz is the rumored speed of the processor in the PSPGo, potentially matching and even exceeding gamecube visuals.

We'll see.

emulating the ps2 is quite difficult, even the latest most powerful pcs you can purchase have some difficulty, kind of ironic

but if they could it would be cool

It forces desktop processors to emulate very differently-designed, specialized processors.

DrWan - 173 days 22 hours ago

bc the PS3 right now is capable of running in game music but only if the developer wants to.

For me, I really dont use in game music, bc I think a game's full experience needs to be experienced with the music that's provided with the game. If you are turning on your own music during a game, then there is something seriously wrong with that game's music.

Unless it's some portion (online maybe) of the game that do not have much music then I guess it's justifiable. But even then...u will be so concentrated on the gameply u won't notice ur own music in the background anyways

i guess its so people who own a PSP-2000/3000 don't feel as if they got jipped.

I still think Devs are required to use 333mhz of the processor and not over it because of compatibility purposes, unless its for exclusive apps or somethin...

Additional frequency does not help in that regard. This would mess to much with the timing. You wouldn't feed security through your only execution path (well, sure of some sort), but possibly with additional HW or such, not with just a faster CPU.
