no the psp is not stronger than the ps2, it has more megahertz but that doesn't mean it's stronger. just like with amd and intel, or in itel new vs old the new have less gigahertz but are still 2-3 times as fast.

PSP is newer than the PS2, so your argument that it's weaker is no supported by the latter part of you comment.

As for the PSP, it has the same amount of RAM as the PS2, and similar processing speeds. The difference is that the CPU has one vector unit instead of two. This seems like a weakness until you take into account that the vestor units were used for rendering, but would mean greater power consumption. So the PSP transfered half of the rendering to a list of hardware rendering on the GPU. This also includes texture compression, the one thing the PS2 lacked (due to Sony realizing too late the design was incompatible).

Combine that with the same amount of system RAM and VRAM as the PS2, and the PSP is at least as powerul as the PS2. What kept it before was the CPU speed caps, which didn't hinder shading and texturing (as those are generated by the GPU and hardware rendering), but the polygon count, framerate, and draw distance (which are generated largely by the CPU).

Now the only thing making the PSP's power not apparent is the low resoution. Yet upscaled screenshots do show graphics as good as they actually are.


I agree with all the parts mentioned up there , except the Vram ... wanst that 4-2 mb to the PS2 ? I dont know where I read it , but I know that it doesnt matters because the resolution difference . Just wandering seeing that you know more about there hardware spec. than me .


 It's 4+2.It has 4MB of EDRAM, just as the PS2, and another 2MB of hardware rendering, instead of a second vector unit. Plus with texture compression, the texture memory can fit more, and the lower resolution will allow even more with the frame buffer (especially with the CPU cap away).

As far as I can see, the PSP has 4Mb of embedded DRAM, which is split into 2 seperate chunks of 2Mb, one if dedicated to the GPU while the other is dedicated to the Media Engine.  The PSP originally comes with 32Mb in DRAM for the CPU, but can earmark more memory from this 32Mb for the GPU if it needs.  The PS2 has 4Mb of dedicated GPU memory which is double the PSP's and it can also earmark memory from the main onboard 32Mb for graphics processing as well.

The only difference now, is that the PSP Lite comes with 64Mb of main board memory, doubling what it has in the original PSP.  This is supposedly earmarked for game file storage to make games load quicker over the course, but I reckon all this 64Mb can be used for graphics as well.

So theoretically, the PSP can call on more GPU memory than the PS2 if need be.  Also the PS2's video resolution is significantly higher normally than the PSP's.  So effectively, the PSP only need to render graphical information at roughly half the resolution of the PS2, which means it should be able to create more lavish 3d environments compared to the PS2.

 Wow thanks , I never knew this litle bit of info . Also , could you tell me what is the usuall resolution for PS2 games . I know it can go up tp 1024*768 , but seeing how week is GoW2s ,,HD" version Im starting to doubt that any game uses the max resolution . I only want to know this for comparison and nothing more :)

Sony's largest success in gaming is a fairly conservative upgrade over it's previous system. The PS2 was sold on the premise that it would play PS1 game, but look better. Oh and hey, we threw in DVD functionality. Such a tactic might not be a bad choice.

 Typical PS2 resolution is 480p, either in 4:3 or 16:9, same as the Xbox and GC, although the GC had the fewest widescreen games due to having the smallest fremebuffer.

Thanks , than the image has to be much more ~ 4 times the size of a PSP game right ? That gives yet again a huge advantege for the PSP . Unfortunatly the only games that seem to use this are CC and CoO :?

 As I mentioned earlier, the CPU cap did keep some things limited. Also, as with the Wii, developers didn't seem interested in taking advantage of it until recently.

Actually , I find it odd , that few games really look like PS2 games . IMO the PSP has so much potential , to ba dthat piracy keep away potentially great developers :(

Don't forget, the PSP has really only been on the market 3 years this Xmas.  I honestly feel that a large number of the developers for the PSP aren't really tapping into the full power of the handheld.  This will come and there are signs that we are getting closer.  Chains of Olympus is looking twice as good as any other game on the platform at the moment.  Crisis Core is looking damn good as well.

Also, Chains of Olympus is looking as good on the PSP as GOW and GOW2 do on the PS2.  Both these games were released 6 and 8 years respectively into the consoles lifetime.

If the PSP manages to continue for a good few years yet, then I reckon we could very well be in for a treat.

Why would they need to make a psp2? They have firmware updates to make it better, come on it takes pictures!!!

If they do make a psp2, I dont think it will have phone features....(it already does with Go Explore! In Europe whenever that is released(video chat kids!))
