SEGA's next gen arcade board won't be the most powerful anyway.
I agree. Sega's next gen arcade board probably won't be as powerful Xbox2 let alone PS3. PowerVR is providing the graphics hardware again, but this time I doubt PowerVR can come up with a single GPU can can rival what is going into Xbox2, Revolution and PS3. the only way that a PowerVR-based arcade board could rival or surpass nextgen consoles, is if they use like, maybe,
four PowerVR5 GPUs. or even like maybe two overclocked PowerVR5 GPUs with *alot* of RAM. otherwise, I just don't see Sega's new arcade board being as powerful as the new consoles-- the reason is, I doubt Imagination Technologies / the PowerVR team has enough resources to compete with ATI or Nvidia, this time.
It's not like last time, when PowerVR2 could, performance & feature-wise, whip a much smaller Nvidia who had no 3Dfx/Gigapixel and alot less SGI. or an ATI that lacked ArtX/SGI and Real3D. Now that Nvidia and ATI have absorbed a great deal of engineering talent and technology/IP from the rest of the 3D graphics industry, I just do not see how PowerVR can compete anymore, at the highend. unless, PowerVR has also absorbed some additional talent, and comes out with an absolute miracle-chip.
on the otherhand, I am not ruling out a very agressive Sega board with 2-4 PowerVR5 GPUs, plus some additional custom hardware (i.e ELAN in N2) and alot of RAM. ...yeah, i know the new Sega board wouldn't *need* a seperate T&L unit like the N2 did, because PowerVR would have put Vertex Shaders into Series 5, thus making PowerVR5 a real GPU, unlike PowerVR2... So i just gave ELAN T&L as an example of additional hardware for an arcade board that isn't found (seperate) in consoles (Xbox, Cube) or at all (DC, PS2)... now back to what I was saying.... even with two Dreamcast 3D accelerator chips (CLX2) the N2 is able to surpass the PS2 and pretty much rival the Gamecube and Xbox. that's pretty much because of the ELAN unit and the large amount of RAM in N2.
therefore, a new Sega board with, say, 2-4 Series5 GPUs and some other supporting hardware, plus maybe 1 or 2 *very* powerful CPUs, and 512 MB or more RAM, might be able to surpass Xbox2 and perhaps even rival PS3 & Rev in actual in-game visuals.
but that is probably two to three times *more* than what SEGA will have actually gone for in their new board. so more likely, they're coming out with a more modest board with 1 or 2 PowerVR5 GPUs (instead of 2-4) and just 1 fairly fast CPU, *no* addional support hardware (like ELAN was for N2) and just 256-512 MB of RAM. Thus, at best, the new Sega board might come close to Xbox2 performance. or maybe not quite. and certainly *not* close to PS3 and Revolution performance.
well, that's about all i have to say. Sonic did the short version, I did the long version. heh. thats my speculation for tonight on this subject.
