@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...

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

[meowmmmmm]

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

[NewLynxChannel]

@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 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]

@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]

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

[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?

[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.
