Comparison of processor types

Hi,

I have to put a few lines in a report to management which will explain the difference between PA7000 and PA7200 processors. Nothing too complex but just enough to show that they are indeed different. Anyone point me in the right direction?

Thanks

Thanks for that, it gives me some detail of the PA7200 cpu, however, I still need comparable info on the older PA7000 cpu, particularly why they should not be viewed on a like for like basis.

Re: Comparison of processor types

Hi,

I've found some information on servers that used the PA7000 chip...

Server Speed Mhz Cache Kb
H20 48 128
H30 48 512
H40 64 512

There were also G30, G40, I30 and I40 servers and date from early 1993.

None of the PA7000's appear to have had a floating point co-processor included.

Regards,
John

Re: Comparison of processor types

In addition to above interesting URL:
.. PA7000 is not a part of the PA-RISC family, for example it's not year 2000 compliant!

Re: Comparison of processor types

That's a great start, specifficaly I'm comparing K220 and K380 servers. The floating point and cache size differences seen usefull.

As for Y2K, we haven't found the fault yet!

Re: Comparison of processor types

Alwyn,
Before I start to point out the differences between PA7000 and PA7200??? Are you sure you want to compare those two CPUs? Because the K220 has a PA7200 and the K380 uses a PA8200

T. M. Louah,
Of cause is the PA7000 a member of the PA-RISC family and how can a CPU be not Y2k compliant?

Re: Comparison of processor types

btw. the PA7000 has the codename Mustang or PCX-S. You will find the PCX-S on http://cpus.hp.com

Re: Comparison of processor types

If that's the case then SAM's lying. System properties on the K380 are showing CPU Version 1.0 PA7000.

The servers were bought less than two years ago and there seems to have been some changes to the specified processors for increased speed.

Ideas?

Re: Comparison of processor types

OK, interesting point why SAM shows PA7000, but I assume we can postpone this question ;-)
Major difference between the PA7200 and PA8200 is, that the PA7200 is PA-RISC 1.1 with 32 bit and PA8200 is PA 2.0 standard with 64bit.
You will find some documents about the major differences like: http://cpus.hp.com/technical_references/advperf.shtml

Re: Comparison of processor types

Thanks,

enough buzz words in there to fill several management reports. Could use it for months!
