PS4 To Use PS3 Cell Technology - Wii 2 Confirmed

Cell is a single core processor, it has a single general purpose core that acts as a manager for the vector units.

I thought this was already made clear to PS3 users?

[QUOTE="bungie93"]I doubt they would do that considering the Cell has been a complete failure. Multi-core processors are the way of the future.AnnoyedDragon

SPE's aren't vector units. They're fully functional cores capable of operating independently from the PPE. Their only restriction is that they can only directly access data in the local store, and need to DMA data from main memory into the local store if they need to use it.Teufelhuhn

They are not fully functional cores.

I am not a technical expert that knows every term like the back of my hand, but I know the SPE's in Cell are not fully functional like its power PC core.

[QUOTE="StingerVXIII"]I'd liked to point other that this is a RUMOR For all you fanboys gushing from your vaginas because its "based" around cell. That doesn't automatically mean its gonna be a PS3. They could always add more hardware and stuff and upgrade it to a much superior console then PS3. Also to the lems and sheep. You're laughing at Sony now, but do you know Nintendo's and Microsoft's next consoles? Oh I thought so you don't. I wouldn't get excited over a rumor. Nintendo and Microsoft are both casual and MS keeps showing more and more signs of going casual. Don't set yourselves up for a huge self-ownageRiverwolf007

Ermm, eww?

they have their own little cache like regular PC CPUs and with PC cpus they're not directly connected to the memory anyway (exeption of I7s) they go through the northbridge

I'm curious as to what other distinctions you think there are between the SPE and PPE. I already mentioned the big one, that SPE's are cut off from main memory. But I'm not sure what it is you think they can't do functionality-wise.Teufelhuhn

What do you want me to say? I probably look into it more than most PS3 users, but that doesn't mean I'm an expert in hardware architecture. So no I am not clear on the exact limitations, I only know they are specialised in their capabilities after repeatedly reading/hearing about it over the years.

One example of it being said. (1m forward)

So what is someone in my position supposed to think? Stick with what I have heard to be the case since the PS3s launch, something that only seemed to become a problem now. Or call PS3 Cell a 7 core processor when I specifically remember it being debunked at some point.

If it is a 7 core processor then I haven't seen any PS3 games demonstrate that sort of performance, of course that could be the memory bottleneck.

[QUOTE="skektek"] You don't know the terms but you know that its not a fully functional core? Did you read this on the internet or did you hear it from someone?AnnoyedDragon

I said I wasn't a technical expert, like most people here I pick stuff up as I go along.

As long back as I remember people agreed that Cell has a single core processor that acts as a manager for the more specialised SPE's, not a 7 core processor like PS3 users hyped around launch. If vector processors is the wrong term then I will correct to the right one, I only kept using it because no one has had a problem with it until now.

However I will not call it a multicore processor, only one of the cores supports the full range of tasks a processor is expected to do. It is a misleading term, I might as well claim my GPU is a 112 core processor, there is a difference between capabilities of the stream processors in my GPU and the cores in my CPU.

I guess that depends on what "people" you hang around with. In this case these "people" weren't very well educated on the topic at hand. Any one of the SPUs can function independently as a fully functioning core. If you want to witness this first hand simply load Linux on your PS3.skektek

Sorry, as I said I'm not changing my views.

You want to call me uninformed because everything I have seen and read up to this point refers to it as single core/7SPEs? Even Carmack just now referring to it that way (I know, appeal to authority, my bad). Well let's put it this way, time with your claim being demonstrated everywhere is going to do a better job at convincing me; not the pressure of two people on a forum disagreeing with me.

Think of it this way, if you are right then I'll convert to your views eventually anyway.

Great. Thanks Wii.

Xbox 720 will be my main console next gen then.

Cell is a multi-core process, even Carmack said it there. Each unit is a fully functional processor. It's doesn't have all the bells and whistles of the central unit, but that doesn't make it not a core.

What would be correct to say is Cell isn't a symetric multi-core processor, where all the core are essentially identical. Specialization means the cores are good at somethings, lousy at others, making programming more complex that working in the symetrical environment where you can count on each core doing any task assigned to it equally as well as any other core.

[QUOTE="Verge_6"]'Based on' is such a loose term that leaves so many possibilities.dgsag

Even so, if they don't radically upgrade the rest of the hardware, we won't be seeing much more technically advanced games than possible on the PS3.

How much more technically advanced do you want them to be?!

"Specialized" doesn't mean "vector unit", nor does it mean that the SPE's are lacking functionality. It just means they do some things better than other, mainly because of the way memory and local store is set up. It might sound pedantic to you, but when you say "can't" as in "the SPE's can't do certain things", I take that to mean that it mean that it's impossible for them to do those certain things. Sure there's stuff you wouldn't want to do on the SPE's, but that doesn't mean it's impossible.

The reason you don't hear the Cell referred to as a "7-core processor" is because it doesn't have symmetrical, identical cores. It's not like a Core 2 Quad where all cores are the same, and you would have the same performance on any one of them. Instead you have two different kinds of cores with different performance characteristics, and that you have to write different code for. I think this is what Carmack is talking about, in that video: you have to carefully choose where you do your work. Still I don't think "multi-core" is the wrong term, since it's definitely anything but single-core.

BTW I'm not attacking you or anything, and I hope it doesn't sound like I am. I don't expect you to know anything, or to just instantly trust anything I say. In fact you should be skeptical and careful, especially with so much exaggeration and mis-information floating around the Internet. I'm just doing what happens on other technical forums where I hang out: when you see someone claim something you disagree with, you call them out on it and make your case. :P

The only difference between the SPU's Local Memory and traditional CPU cache is that the Local Memory doesn't contain additional logic to increase the speed of some operations.skektek
