Processor Speeds - How to compare?
Hi All, I am looking at a new laptop, and I don't really understand how to compare the processor speeds. For example, we bought one last year (about 10 months ago I think) that has a P4 (2.6GHz) processor. One of the ones I am looking at new today has Intel Core Duo T2400 (1.83GHz) processor. On the face of it, the older machine is much faster. But does that 'Duo' thing mean I am getting two 1.83GHz processors = 3.66GHz so the new one would be much faster? This is probably wishful thinking, but is there some way of just comparing the two so that, if the first one is deemed to run at '100' (whatever that may mean), the second one would run at 130 being 30% faster? Is there a website that dumbs it down to that kind of level somewhere out there? I can find lots of review sites, but I would really like to put two options side by side. Thanks!

The key (according to intel) is a cpu should not break the 130watts heat output barrier plus the die size. As the clock speed climbs heat output is a hugh issue...so to get round that they are looking for different ways to give the cpu grunt and since the die size is now so small they can offer 2 and even 4 cores in the CPU. In order to not break the heat limit they wind the clock speed back slightly and as the heat output is a square (or cube) of the clock speed you save heaps of heat, hence 2 cores is easy... > This is probably wishful thinking, but is there some way of just > comparing the two so that, if the first one is deemed to run at '100' > (whatever that may mean), the second one would run at 130 being 30% > faster?

Is the old laptop you have fast enough? if so why worry...the biggest limiter is hard drive speed and ram. Look for the biggest fastest spinning hd and work from there IMHO. Pick a laptop that can hold 2 gig of ram, get the biggest screen you can afford...makes life so much easier. regards Thing |

<thingy@nocommy.commy> saying something like this: >Yes and no. Intel marketing at its finest. Bare in mind AMD's Athlon XP marketing names, 2400XP always reminds me of 2.4GHz, but it's not quite true. -- Cheers, Waylon Kenning. |

AMD has been dropping prices on select CPUs recently (e.g. Athlon64 3500+ has basically dropped 40%-50% in the last few weeks), and AMD are expected to make a couple of official announcemnents at about the same time Conroe is unveiled (my guess is yet another price drop, and reverse-hyperthreading on their AM2 CPUs). You know you have to do something when the competitors mid-range offering obliterates your top-end product. |

The old laptop that this new one is replacing is actually much older (four years old now) the batteries are dead, the CPU is a PII 550MHz. The one I was comparing it to, just hapenned to be the last one we purchased. I am thinking of this for the required specs (I want it to last at least three years - too much hassle changing PCs!): Criteria Requirement Processor (Type) ??? Processor (MHz) ??? PXE? TRUE DEP Compliant TRUE L1 Cache (KB) 32 L2 Cache (KB) 1024 FSB (MHz) 800 RAM (MB) 512 (Upgradeable to 2Mb) HDDs (GB) 160 HDDs (RPM) 7200 HDDs (Type) SATA - Not sure about this? DVD / CD CD-RW / DVD-RW / Dual Layer FDD? TRUE USB Ports 6 Mouse PS2 & USB KeyB PS2 & USB Serial Port?

I posted my current thinking on specs in reply to Thing's post. How would the new Conroe stack up in that context in terms of making a difference compared to the Duo 1.83Ghz?

Basically, Conroe is fast - real fast (and very power friendly). Waiting for Conroe to arrive is a smart move primarily for the sake of the ripple effect (or should that be tsunami effect) it will have on existing CPU pricing, and subsequent OEM products that include them. |
