Which is more powerful - Pentium D or Pentium 4 with HT?

idata — Fri, 14 Jan 2011 20:29:55 GMT

I am setting up a small office network, and just got in some Dell GX320s and GX520s from another location. All units have 3.0Gh cpu's and 1 Gb of ram. I will add ram to some units. One of the units will function as an Internet server running Qbik Wingate and another will be an office-wide application and database server.

The GX320s (so far) have a Pentium D, which I believe is a dual-core cpu (not sure yet whether they are the 800 or 900 series). The GX520s have a Pentium 4 cpu with HT (1 core, 2 threads).

Questions:

1. Which processor is likely to be more 'powerful'?

Or will it make much difference?

2. About the Pentium D, assuming it is a dual-core cpu, do BOTH cores run at 3.0Gh, or is the clock shared/split betweem the two cores? I further assume

that each core has it's own independent cache ram (seems logical anyway).

I will appreciate any info on the above. Thanks in advance for your help.

1. The Pentium D's are more powerfull.

Hyper-Threading Technology allows processors to function more efficiently when running multiple tasks, however a dual-core processor has a second physical core with its own set of dedicated execution resources. Therefore everything else being equal Dual-core processors offer greater performance than single-core processors with Hyper-Threading enabled.

2. Yes both cores run at 3 GHz and Yes each core has its own L2 cache ram. 2x1MB for the 8 series and 2x2MB for the 9 series

Quual, thx for the info.

One thing I forgot to ask - are these processors 32 or 64 bit CPUs?

I've just realized these Dells were reloaded with a 32bit version of XP Pro (2002). Hogwash.

Any help sincerely appreciated.
