Nice. But is the 3.2GHz for comparison purposes, or will Cell really be clocked that low? Hmmm, I'm disappointed if the latter. PEACE.

With the GPU its going to be 2 teraflops.

If that was hinted at me was the cell would have 1 of the 8 SPEs marked bad, but another would be reserved for the OS. That would give you 6 SPEs. Let's see if that actually pans out.

218 Gflops. ok

 

[Dave Baumann]

Actually, it looks like there are two pools for RAM - one for system/Cell and one for graphics, rather than a single UMA. I wonder how interchangable the data is between them.

if that is true the actual gflop number will fall for what is useable in games would it not

Is that 256MB XDR ram AND 256MB GDDR???? Or am I confusing myself? :?

its both. For a total of 512 megs . We don't know if its 256 that only the cpu can acess and another 256 that only the gpu can acess. Or if they can both access both pools of ram.

 

[Dave Baumann]

No, XDR would be for Cell and GDDR (probably 3) for the graphics. Its beginning to sound like NVIDIA only had time to change the host interface.

 

[nAo]

even if GPU can't access XDR mem CELL CPU can feed it

 

[DemoCoder]

Dave, Why is that, because they didn't use eDRAM? Even if they had all the time in the world, they may have still decided against eDRAM.

 

[Vaan]

Seems obvious that they will use the 8th spe hole to attatch the GS/EE chip.

 

[aaaaa00]

So now it's:

256 XDR + 256 GDDR

vs

512 GDDR + 10MB EDRAM.

Hmm.

 

[Pugger]

Does the 3.2 ghz rating mean that theres more similarity between the PPE in Cell and the cores in the 360? Funny how they are both the same clockspeed. And MS seems to have done a good job to get as close as it did to the Gflop rating of the Cell in PS3. Still adecent advantage mind but lower that most people imagined

 

[persiannight]

Doesn't look all that radically different then 360.. kind of what we all expected no??

Gamespot update 2

"Sony also laid out the technical specs of the device. The PlayStation 3 will feature the much-vaunted Cell processor, which will run at 3.2 Ghz and feature 2.18 teraflops of performance. It will sport 256mb XDR main RAM at 3.2 Ghz, have 256MB of GDDR VRAM at 700mhz, a detachable 2.5 inch HDD slot, six usb 2.0 ports, Memory Stick Duo, a SD slot, a compact flash memory slot, Compact flash slot, 2 hdmi outputs, 1 av multi out, 1 SPDIF optical output, and 1-gigabit Ethernet built in port "

Yes definately

 

[j^aws]

25 GB/s for XDR and 22.4 GB/s GDDR?

Don't bet on it, 8th will be deactived to improve yields.
