Processor comparisons


Hi

I have a mixture of servers using various processor combinations

PA-8700 750Mhz & 875Mhz
PA-8800 800Mhz
PA-8900 1Ghz

I'm looking for a definitive processor roadmap and benchmarking so I can compare performance between PA-8700's and PA-8900's for example.

Regards

Andrew

Re: Processor comparisons


Thanks

It seems this is in part some of the information I was after

"Thus, each PA-8900 core will deliver more performance than the PA-8700+ processor"

But if anyone has access to more specific performance comparisons I'd be interested to read them.

With thanks

Andrew

Re: Processor comparisons

Hello,

It depends of the type of server but here are some value :

PA-8700 750Mhz ==> rp5430-2 PA-8700 750 1p 14200 Tpm
PA-8700 875Mhz ==> rp5430-2 PA-8700 875 1p 15506 Tpm
PA-8800 800Mhz ==> rp7420-16 PA-8800 1000 2p/1c 47600 Tpm (23800/cpu)
PA-8900 1Ghz ==> rp7420-16 PA-8900 1100 2p/1c 52900 Tpm (26450/cpu)

Regards
Patrice

Re: Processor comparisons

The PA-8700 CPU is an 750 or 875MHz CPU that has 2.25MB of L1 cache.

The PA-8800 CPU is 2x 800MHz PA-8700 CPUs on one chip that each have a 1.5MB L1 cache & share a 32MB L2 cache

the PA8900 CPU is 2x 1000MHz PA-8700 CPUs on one chip that each have a 1.5MB L1 Cache & share a 64MB L2 Cache.

So they're all the same technology, but they have ramped up the speed & cache as they go along.

The PA-8900 1.1GHZ is likely to be the last PA-RISC chip that HP makes.

Hmmm,

Our PA-8800's are 1Ghz...
