I'll have to correct you sir, but..

The Cell has 1 main core at 3.2Ghz and 8 SPUs (mini-powerful worker units), 7 of which are usable to the devs and coders since the 8th is dedicated to the XMB. I do believe Sony themselves are only able to access the 8th SPU for system updates and what not.

With all the development that is going into mobile processors now, I've been anticipating the use of CPU clusters for a while. If we go too long without breaking through the bottlenecks in single core processing then it's only a matter of time before they release a chip with a bazillion mobile processors for your desktop.

(Yes I've seen the articles on quantum and optical processors, and they look promising, but until we have them in our hands there is no guarantee anything will come out of it.)

What I read is that they had so much trouble producing good chips that the 8th core was permanently disabled on all units, and the 7th core was reserved as a backup for when one of the others died.

Effectively the Cell (in the PS3 anyway) only has six SPUs to program for.

Actually there is one of the 8 spu available that is deactivated and one for the os so there is 6 available to the developers. The xbox 360 cpu is also based on the cell architecture it's a 3.2ghz triple core hyper-thread so 3 core and 3 other logical cores are available to developers.

...however, many games (especially first-person ones) are inherently not that parallel-able since depend on user real-time input to respond.

See Amdahl's law


Quantum processors will do little for games.

I wish the government spied on us more. Maybe they'd bring down the price of consoles?

Surely terrorists scheme in their living room and hang big blueblue prints up on the wall of their plans.

 

Anyways, 16 cores for a console seems a bit absurd in relation to how games are developed now(or developers WANT to make games) but if they were to make highly threaded games from the get-go I think it could work out pretty well. It had might be harder for individual developers to make their own engines but if they were to use other peoples' engines (which 'they' probably already do) then I don't see where the problem is.

 

The PS3 being especially hard to code for seems like a completely separate issue that didn't have to do with the cores as much.

Definitely possible as Microsoft wanted out-of-order execution for the tri-core Xenon but it wasn't ready in time for a 2005 launch. With that said, a quad-core Power7 isn't hard to believe at all. In certain integer workloads, the tri-core Xenon can easily match a Core i7 quad at the same clock speed.

If they decide to stick with the same volume then yeah. Considering the 360's current volume, their transistor budget proportionate to first generation silicon could easily allow a quad-core Power7 coupled with a modern GPU.

I'm now convinced that It's going to take a lot more than facts, evidence and Amdahl's Law that to dislodge the "lazy devs" fallacy that a lot of people seem to have imprinted inside them.
post #70 of 303
I dont see this being to far fetched considering its slated for a late 2013 release. Considering the AMD rumor in both upcoming consoles..you can get a 16 core amd for $500 right now. Give that a year and some change to drop in price and go onto newer cheaper to make architecture. Seems plausible to me.
