Siggraph 2008 Passive Head Tracking using Cell processor

[meowmmmmm]

A friend at IBM has confirmed that the PS4 is going to use either a 'Cell Quad - 32' (4 Core, + 32 SPE's), or the 'Cell Oct - 16' (8 Core + 16 SPE's) running at 5.6 GHZ. For PS3 Compatibility, it will even contain the RSX on the same chip. Both processors have been prototyped at 32nm process and have about (1.8 Billion Transistors.) Performance is about 480,000 MIPS. For comparison, the Cell BE in the PS3 is about 45,000 MIPS

@meowmmmmm Nonsense. You can't even be sure Sony will use IBM processors again. And even if they are, there's been many articles around the web about how Sony intends to use a regular multi-core processor on the next console generation to avoid the problems that CBEA caused to the developers with the Playstation 3.

Also, PowerXCell 8i was the last update to Cell lineup. IBM is not going to develop new Cell chips, although they will continue manufacturing and selling the existing ones.

[meowmmmmm]

@NewLynxChannel Wake up. Sony is not going to change the architecture again when developers already know the machine. They are not going to change the CPU and overpay for an Intel chip. Programmers have complained about programming every Playstation every released. To get the same performance from an Intel chip compared to the Cell, it would have to be a Core 2 Extreme. When PS4 comes out, that would have to be a very fast i7. Sony's not going to pay Intel costs & change the system again

[NewLynxChannel]

@meowmmmmm Then search for the articles and see for yourself. There's one easily reachable on Softpedia.

Also, even a Wolfdale chip can already outperform Cell on everything but floating-point operations (because desktop CPUs don't have RISC SIMD units like the SPEs). Cell was a very good processor at the time of release, but it's been five years and now it's a $38 chip. There's only so much it can do compared to what's available today.

[meowmmmmm]

@NewLynxChannel Why would I waste my time, when I know people who work for IBM. You are wrong about E8500. It can outpeform the PPE in the CELL, but not even a single SPU. They contain custom hardware for vector processing, video encoding and more. Even then, the next PS4 CPU is going to be 42 times more powerful than the CELL. The current fastest I7 is not even fast enough. Only the IBM Z196 comes anywhere near close enough, and that costs a fortune.

[NewLynxChannel]

@meowmmmmm The SPEs only outperform desktop CPUs on floating-point operations, exactly because they are structures absent on desktop GPUs. But desktop GPUs, which do have similar structures, easily outperform Cell in that aspect.

Besides, this is nonsense. Sony isn't even planning the next console yet, your claims about its CPU is nothing but completely unbased speculations.

And please! Do you think "I know people who work for IBM" will convince anyone?

[NewLynxChannel]

@NewLynxChannel "Absent on desktop CPUs". My Mistake.

[meowmmmmm]

@NewLynxChannel Wow you copied wiki nearly word for word.  When you actually know about the hardware / software side of Cell processor we can have a conversation, until then, stop paraphrasing crap that was entered by a 5 yr old on Wikipedia.

If the Cell is slower than Desktop PC processors, then why is IBM using it in Super Computers?

For the record, Sony was begging initial development on the PS4 even before the PS3 was even released. The same happens for the 360 and Wii.

[NewLynxChannel]

@meowmmmmm Really? Show me this Wikipedia page that says the same as I just did, I wanna see it.

First, IBM no longer uses Cell on supercomputers, they use the improved PowerXCell 8i. And they use it because supercomputers benefit from the advantage on floating-point operations (like I said, the ONLY area where Cell outperforms most desktop CPUs, since desktop CPUs don't have SPEs). But the single-core Cell with 512 KB of cache is definitely not a good option for home computers.

@meowmmmmm Continued...

And where are your sources for that last statement of your comment? Are you going to tell me "I know people that work for IBM, for Sony, for Microsoft, for Nintendo, for NVIDIA, for ATI, for RAMBUS..." and so on, and expect me to consider that nonsense a good source (or believe that at all)?

[meowmmmmm]

@NewLynxChannel Get a life. I know people who work for IBM CPU department, and I live very close to Microsoft!

[NewLynxChannel]

@meowmmmmm So you're saying you're your own source and you think other people will find that a good idea, right?

[meowmmmmm]

@NewLynxChannel I just reeled that I can count all your braincells on one hand, and that why adding 2+2.at the same time.

Message me again when the PS4 specs are officially released, and you can tell me how wrong you were.

[NewLynxChannel]

@meowmmmmm What, you saw those specs you your crystal ball? Why don't you ask it for some information that makes sense next time?

Also, trying to insult me by saying I have few brain cells? I don't think your age is higher than the number of neurons you say I have...

[RadiantSilvergun3]

They can't release this on PS3. Listen to what he says. It's being done on a QS22 Cell Blade. That thing has around 14 Cells in it. The PS3 only has 6. They could do the Head Tracking (Hell the wIi can do Head Tracking) but they can't do the Ray tracing on a single PS3. Not that well at least.

[Talyis84]

It's still a good display of the PS3's power!

[chunNezumi]

@RadiantSilvergun3 completely wrong. They used 9 blades, meaning it has 9 PowerXCell 8i CPUs. Each PowerXCell CPU has 8 SPEs, compared to the 6 SPEs available on the PS3. This means that they are using 72 SPEs, 12 times the amount in the PS3.

Also, the PowerXCell is more powerful than the Cell in the PS3.

[RadiantSilvergun3]

@chunNezumi I wasn't completely wrong...

[W3iSn00p]

when will they release stuff like these on ps3 publicly??..

this be awesome to play with!

[PS3ddie]

ps3 is the best hands down
