Hi All,

We are in the plan for tech refresh for our customer from pa-risc to itanium.Our existing servers are rp 7420.The processors are spread across 2 cells and total number is 6(single core).

We are planning to go for itanium model(rx 8640) .Could you please tell me whether using 3 dual core CPUs or 6 single core CPU is more efficient.Which option will give best performance results

Current CPUs for this system are all dual core (Intel 9000 or 9100 series).

Hello,

Thanks for your reply.My concern is if we use 3*dual core CPUs for replacing the 6 single core CPUs on the existing server.Will it provide equivalent performance from CPU perspoctive

New CPUs are probably much faster than your "old" machine.

Hello,

Let me explain more .My concern is about the number of CPUs/core.Whether three new dualcore processors can replace 6 single core processors.

The number of cores will be the same, the new CPUs will be much faster.

Consider to buy at least 2 cells, otherwise you cannot use all the I/O slots.

hi,

check this links :

PS : the same number of procesors ( or cores ),
will be much powerfull.

Hi All

I am again repeating..Whether 6*single core CPU=3*dual core CPU ????I want 6 CPUs(speed not cosdiering now) in my new machine.Whether I should go with 6 individual processors or 3*dual core processors.

hi,

3 dual core is better solution if you need to upgrade the number of cpu, but if its single core or dual core its doesn;t mather.

mikap

in my opinion you should buy a dual core cpu's

Since you can only buy dual-cores, there is no need to repeat the question again and again ... only dual-cores are available nowadays.
