So the question is, just how powerful is the Cell? Simple: NOT THAT POWERFUL. Lets explore:
The cell = 9 cores, 3.2 GHz
On top of this, the Cell is at this current phase, reliant on the RSX as a backup. In early cell testing, the RSX was used as both a GPU and a backup cell for data processing. Should the cell fill up or fail at any task, the RSX would take over that task and any others necessary until the CPU could stabilize. However, the RSX was in select cases overloading and then the ER protocols would force the data back to the CPU causing system failure and interruption with data streaming.
Also, the Cell only float 2 Teraflops where a sophisticated PC can run anywhere between 4 and 6. Your average supercomputer can hit over 100TB easily.
Furthermore, the Cell and RSX are restrained by minimal PS3 resources from the RAM. The mPS3 has 256MB of Main RAM, about enough for your average PC to run Microsoft office. Of course, the cell allows games to be played at higher speeds with less RAM because of its 9 cores for data processing, but eventually tehre will come a point where 256MB just wont be enough. Even now, games like Oblivion on the PC require 1GB of RAM to be run at max setting and the Xbox 360 with its only 512MB of RAM cant handle the max settings because of it. Its going to be a problem that will limmit the cell.
O yes, the arguement is back and better than ever. You could say, fresh cows revived it
I had some cows trying to convince me I was nuts, that the playstation 3 rivals "supercomputers" (he then proceeded to say orginal supercomputers which rival the processing and graphical power of most current day calculators...nice example cows) Anyways, I decided to check it out a bit more in depth. What I found was that the PS3 is not only an outdated piece of harware, but its farily low tech by "supercomputer" standards.
Below is a lost of the PS3 technical specifications. Keep in mind that much of it is give in take. It plays alot of stuff, but DVD, DVD R, DVD RW and DVD R+ are just fancy names for DVD.

Now I will give you the specs of your state of the art Supercomputer vs the PS3 (SC to the left, PS3 to the right)
Nvidia 7950................RSX (comprable to the Nvidia 7900 in terms of raw power) clocked like a G70
4-6 TF of RAM....................dual 256 MB PCI (256 Main)
Dual/Tri Core 4.0 GHz pentium D celeron with hyperthreading..........1 VMX vector unit per core, 3.2 GHz
250GB-1 TF of System Memory...............80 GB of compact flash storage
Dolby 12.1 surround sound card.................7.1 surround sound output
Floating Performace - 80-100+ teraflops ..........2 teraflops
In terms of performance, the supercomputer can load over 2000 times as fast as the PS3, with superior output for graphics, sound, system cache and so on.
in comparision to this dell http://www.dell.com/content/products/produ...on=specs#tabtop the dell is superior
when compared to this alienware state of the art ALX model gaming PC, the PC is on top by a long shot http://www.alienware.com/product_detail_pa...DEFAULT#pdp-nav
heck, the PS3 is even beaten out by Apple Computer's iMAC:
1.83GHz Intel Core Duo with 2MB shared L2 cache
512MB (single SO-DIMM) 667MHz DDR2 SDRAM
160GB Serial ATA hard drive
Slot-load 8x double-layer SuperDrive
ATI Radeon X1600 graphics with 128MB GDDR3 memory
So point is cows, the PS3 is comprable to a mid range PC, not a high end PC or a gaming PC that was built this year. PCs have advanced beyond PS3 with things like the PhysX Ageia physics card, the Nvidia 7950, Tri Core processing and so on. The PS3 falls into a range with the 400 dollar gateways in terms of sheer performance, which is sad considering atleast 50 bucks of teh gateway is going to pay for the monitor that is thrown in.
Basically, the only thing setting the PS3 above any PC or above the Xbox 360 is the Blu-Ray player. On the flipside, the initial reviews for Blu-Ray were negative, sighting its cost and size as a waste because its quality for the first titles was actually inferior to that of HD DVD, and it was comprable to regualr DVD9. Shame. http://reviews.cnet.com/4520-8900_7-5600201-1.html , http://reviews.cnet.com/Samsung_BD_P1000/4...7-31799185.html
So in a sense you are getting what you are paying for. A supercomputer would set you back 4-6 grand no sweat. The PS3 is costing 600 bucks, but its giving you a bit more than its costing you. Yes its true, from a technical standpoint the PS3 is cheaper than the sum of its parts (but so are most PCs, and so is the Xbox 360). That doesnt make it cheap, it means you arent paying premium so dont expect it.

Making a long story short, the cell is a breakthrough in modern computer science, but not a landmark. You need to understand, the cell was build specifically to run small applications and datastreaming that would not require it to overclock for any reason. It was built originally to run the new GE catscan machines and power Xray machines for medical useage. As far as raw power goes, the Cell is by no means the most pwoerful or the most advanced CPU that exists. It is build for small PCs and devices with less than 9 systems operating on them at low speeds.
keep in mind that nothing is certain or nailed in stone, and that above all, a PC isnt the same as a console. I give you the comparison because I dont ever want to hear the PS3 is a supercomputer arguement again, not because its fair. Also remember that the cell is restricted by the PS3, its maximum potential for speed and processing power as a CPU isnt fulfilled in the PS3 architecture. PS3 plays games and nothing else, so it economiizes to do so, but it isnt the best environment to examine the power of a new CPU or GPU.
