So, 1 PE after-all or is this just for GDC 2005 ?

[one]

mmm let see..

the highest feature for the chip produced from toshiba ( the chip in ps3? )

4000 Mbit/sec per pin

and 521 Mbit per chip , 16 bit/bus

let assume a 4 chip 4 channel 16 bit bus configuration , we have a pool o 256 MByte at 32GigaByte/sec

Ok these are the final spec of external ram pool on PS3 , ok ?

What is almost sure now is PS3 uses 256Mbit chips. Then, if the release of PS3 is in early 2006, the speed is 3.2Gtps. Thus

256MB XDR DRAM (3.2Gtps) (256Mbit * 8 @ 128bit) = 51.2GB/s

or

128MB @ 64bit for Cell + 128MB @ 64bit for GPU = 25.6GB/s for Cell + 25.6GB/s for GPU

Now, how much eDRAM is on a CPU and a GPU is another question...

ps2: 32 MB- 3.2 GB/s

GC: 24 -2.4 GB/s

xbox: 64- 6.4 GB/s

speed and size in relationship

iirc GC's 24 MB is 2.6 GB/sec which down from 3.2 GB after the entire system was re-balanced which included, but not limited to, Flipper's downclocking from 202.5 MHz to 162 MHz.

This is my theory.

PS3 Main RAM:

-128 bits per channel.
-1 chip (32MB) for 4 APU (1 channel for APU).
-100GB/seg per chip (25GFLOPS for 4 APU).
-256MB of memory.

PS3 Broadband Engine:

-PUs Running circa the 4Ghz.
-4 PE
-APU running around 1Ghz.
-50 GFLOPS per PE
-200GFLOPS in total system.

this makes little sense to me. if we have 4 PEs thus 32 APUs, and only a total of 200 GFLOPs. when a single PE with 8 APUs is supposed to provide 256 ~ 294 GFLOPs depending on clockspeed (4 to 4.6 GHz). an APU is meant to provide 32 to 36.8 GFLOPs, again depending on clockspeed.

 

[Megadrive1988]

oh yeah, a 512 APU ~ 64 Processor Element CPU with 1 GigaByte EDRAM.

the Bogus Engine

yeah this can be produced on 25 nm / 0.025 micron process for Playstation4
by 2010 @ 10~12 GHz. lots of TFLOPs.
