PPC processor in Intel laptop?

Last response: in CPUs

Hi all,
I have a Toshiba NB500 netbook, running Win7, Ubuntu 12.10 and Linux Mint 13.
When running Mint, I saw that the laptop appeared to have 2 processors; one quad core Intel Atom at 1496mHz (@1.5gHz), and one PowerPC 740/750 at something like 280mHz.
Now, I would expect PPC chips in ancient macs, but not in a "new" 2010ish laptop - I had thought that PPC was long dead... maybe I am wrong..

Please could you enlighten me as to what is going on, and WHY it is picking up a PPC processor?
I have some computer knowledge, but am not brilliant! ;-)

Thanks in advance.
Cheers,
Fred

Oh yes.... please let me know if you need any more specs - I'll try my best to find them.

Run CPU-Z for a more accurate description of hardware.

Here is what the testing thing said... it picked up the quad core Atom as a Celeron.

Benchmarks:

1. CPU Blowfish
This Machine 1000 MHz 10.522
Intel(R) Celeron(R) M processor 1.50GHz (null) 26.1876862
PowerPC 740/750 (280.00MHz) (null) 172.816713


2. CPU CryptoHash
This Machine 1000 MHz 86.328


3. CPU Fibonacci
This Machine 1000 MHz 8.791
Intel(R) Celeron(R) M processor 1.50GHz (null) 8.1375674
PowerPC 740/750 (280.00MHz) (null) 58.07682


4. CPU N-Queens
This Machine 1000 MHz 31.437


5. FPU FFT
This Machine 1000 MHz 8.044


6. FPU Raytracing
This Machine 1000 MHz 68.202
Intel(R) Celeron(R) M processor 1.50GHz (null) 40.8816714
PowerPC 740/750 (280.00MHz) (null) 161.312647


So, as you can see, nr.s. 1, 3, and 6, which are all different tests, think that it has a second processor...
I'll try the CPU-Z and get back soon.
:) 
Thanks

"This Machine" is your laptop and that got a rating of 10.522, the two others are references for an intel celeron and a PowerPC. And by the way: Currently the POWER7+ with 5Ghz is the top of the line for ppc processors and everything but dead.

Hang on, these tests were all done on one machine - the Toshiba laptop, so they should all be referencing the same computer... the Celeron is actually an Atom - I know that (the computer says "Atom inside" and on all other OS's it is an Intel Atom).
(You're right about the PPC processor - I know the PPC line is dead... I have a G3 iMac at 400mHz and that's Sloooowwww... ;)  )
I know there's no way that the processor inside can be a Power7 at all! It's a low powered laptop.. but I was wondering what the low powered PPC chip was doing inside it.. - I found out that it is apparently used in printers and such like, but I would have expected that it would not be used in a laptop; it already has a processor, so would not need a second?
Some of my thoughts..
Sorry if I didn't make any sense!
But can anyone tell me why the PPC is in my intel laptop?
Thanks

There is no pps in your laptop! The test results for the celeron and ppc are hardcoded in the benchmark for your reference. Only "This Machine" is dynamic and calculated at runtime.

Okay, Thanks!
While that doesn't explain why it was giving it such good marks, I feel slightly better with the knowledge that it isn't actually there! :D 
Maybe the testing tool sucks, yeah?
