Is this true?

When the developer has to design for the PS3 he has to use the 1 Core and the SPEs to make the game from the beginning to actually see if the game and its effects are working and there are no bugs unlike in Xbox 360 where the developer can developer for 1 core instead of the other 2 to see the developement of the Game. This would make the Game development on PS3 even though its hardware than Xbox 360 come out in the same timeframe as the Xbox 360 because you work with the SPEs the GPU and the Core all at once from the beginning unlike in the Xbox 360 when you can just use one core and then decide later one if and/or when they move along to the other 2 cores. In other words he has to output the near full potential of the Kit provided to him in PS3 from the beginning compared to starting at a much lesser degree in Xbox 360 then moving up

seeing this another question is if GOW is using 1 core is it using the same core which uses sound? because in the X360 documentation it said the sound, OS, media center and xbox live use 25% of 1 core while the rest is for the other elements of the game. so is GOW using 75% of that one core or is it using a seperate core like for example 1 Core for the game and 25% of other for Sound OS Live or is it 75% game and 25 Sound OS Live on one core

Obviously this can't be true as Heavenly Sword was developed on the one core to begin with Ideally all devs will design with a complete system in mind though, aiming to use all it's resources rather than filling up one core at a time. A dev who writes for one core and then moves code onto another probably won't get as much use of the hardware then a dev who's designed his engines for multicore from the start.

the previous beta kits of Xbox 360 i heard was 2 Cores, and before that 1 core. isnt that a transition?

Of curse you can take code runnig on one core and cut bits out to paste into another. The same can be done XeCPU or Cell. The advantage XeCPU has is the code can be lifted as is onto another core, whereas in Cell any code running on the PPE will likely need to be rethought when moved onto SPE. However good design should be avoiding moving threads. It should be aiming to use them from the off. When writing for PS3 devs will be thinking, one way or another, 'we'll use these SPE's to handle x,y,z, and run such and such on PPE'. I don't know how easy or hard it is to make the conversion to SPE. It'd be nice to hear Deano's talk on the matter.

HS was developed on PC and had only made it onto the PPE the last we heard.

So, erm, what's your point?

No.

Alpha kit = Mac G5 = PowerPC970FX dual-processors

So it's equivalent to dual core processor. It's said that Gears of War had used only 1 core until recently, but what did they do with alpha kit I wonder... wasn't Mac G5 for preparation for multithreaded code or does it just refer to its CPU load?

i was under the impression Mac G5s were to enable developers to get familiar with the IBM CISC/RISC processors

From what i can remember...

the whole one core thing came from GoW is running at 30% of the final hardware talk from E3...

since the 360 = 3 core cpu

most deduced from 30% being one core...

fun stuff

I believe Epic themselves in the last 2 or 3 weeks noted it was running on 1 core. And the Alpha kit comment is moot because GOW was running on a 6800U SLI rig.

Oh yeah!

Thankies for reminding me... I totally forgot abvout that
