Rumor: PSP2 will have quad-core GPU |
Ó
Ah, numbers. Sony's already cleared up that 480MHz figure on the PSP Go, but now we have another rumor bringing up more impressive digits that lay in the PSP's future.Eurogamer.es is claiming to have insider sources who say that the PSP2 (note that this isn't the same as the PSP Go) will have a quad-core graphics chip inside its as-yet-unrevealed structure. This is reportedly a quad-core version of the low-power SGX543MP chip, codenamed "Hydra".
Eurogamer's translation of the original Spanish report notes that the single core version of the chip has been demonstrated at CES running Quake 3 Arena at 30FPS. I can't claim to know a whole lot about hardware, so here's more from Eurogamer:
The obvious difference of course is that the SGX543MP is a multicore processor, available with anything up to 16 cores on tap. According to the original report, PSP2 opts for a quad configuration offering notional specs of 133 million polygons per second, and 4Gpixels/sec fillrate, assuming that Hydra operates at the chip's low-end of 200MHz (higher speed variants are also available, presumably for desktop use). While specs like this are always subject to interpretation, these figures are a ballpark match for the original Xbox. However, PowerVR's tech includes tile-based deferred rendering, which should provide a nice performance boost.
The chip is also described as being able to operate as both graphics processor and CPU, so the PSP2 could conceivably use a single chip for everything, which can save power as well as being more efficient from a programming perspective.

if you want an official statement from sony, here it is: "No comment."

They said the core they had running was playing Quake 3 at 30fps. This makes it roughly as powerful as a Riva TNT2 (cutting edge in like, 1999). 4 Riva TNT2s do not equal one GEForce 7800 (roughly the power of the graphics processor in a PS3).
There is a whole lot more to how powerful something is than just how many cores it has, things like cache, clock speed, and pipelines, ram speed etc. factor in as well. A single core may in fact beat a quad core, like the example I showed above.
I'm assuming when you said CPU you meant GPU XD

On top of that, fabrication processes have shrunk quite a bit since 8 years ago. Even something like a laptop nowadays is smaller and runs cooler than an xbox but still allows for better graphics, despite the Windows overhead.
apex is right on one thing though, no chance in hell of PS2 emulation, they still have trouble with that on quad core PCs and the PS3.

There is no reason why Sony wouldn't.
Even with piracy there making Millions.
There probably making more money do to Homebrew scene.
How many of you got the PSP mostly because of it's capability of running homebrew?
PSP became one of the biggest homebrew platforms in the world.

OTOH no dedicated hardware for gpu? now that's an issue. even ps3 has their own dedicated gpu. it gives too much load for the processor to do too many things at a time, i do know that the architecture has more cores to be spent on, but what about the bus bandwidth issue, like memory controller and the likes.

With this chips poly count per second being 155 million (ps2 being 75 mil) at only 200 mhz we could see some seriously impressive graphics. perhaps if they also increase the clock speeds to 300+ we could even get over 200 mil.
Just cross your fingures...

But having multiple cores brings it closer to home consoles and PCs making multi-platform games easier to develop without sacrificing so much. For example DS versions of games available on other consoles can end up looking and playing totally different, like what's the point?

This is a true statement, because even though piracy may be on a rise and PSP homebrew is technically piracy of a PSP, Sony is still selling tons of these units to fill the demand of users who want to get the system in the first place.

Now unless this PSP has a future, such as hardcore gfx or quality gameplay, there is no need for a new GPU or even a CPU since the current PSP CPU works just fine for everything, it's only a matter of execution that determines how well the hardware performs. An example are current emus on the PSP. I find it rather funny how PSX games can run exceptionally well on the portable whereas the N64 or even the SNES emus barely hold themselves together. The hardware is great as it is, but the coding and creation of these apps to run the things you want, not-so.

A single processor for everything may not be a widely used choice for computing, but it is a possible one, with or without command line.
