Processer Help

by sfig1st / March 5, 2007 6:14 AM PST

Hi, I'm new to computers and I am buying a new computer... I am looking at certain processers and it seems that some processers with a Higher GHZ rate e.g. P4-945 Dual Core 3.4GHZ are nowhere near as good as some processers with a lower GHZ rate e.g. E6700 Dual Core 2.6GHZ.... why is this?

Please Help

The Core 2 Duo gets more done with each clock pulse. Sort of how a person with longer legs may go farther with less steps.

ok, that makes sense but than what does the 3.4 GHz/ 2.6GHz mean than?

Nothing but what clock it runs at.

Ok, Thanks this website helps alot but this website doesnt have most of the processers I was looking at just some. So is there somthing in a processers specs that will determine how good it is compared to another processer?

Thanks

I cheat.

In reply to: Re:

I look for reviews of the machines I'm considering and hope they use the same benchmark for the 2 I want to compare.

To compare just the CPU I can cheat there as well. For instance a Core 2 Duo at 2.2 GHz with the 4MB cache will benchmark 10% faster as the 2.0 GHz model with same 4MB cache. Knowing this I can use that web site and compare CPUs that are not on the menu.

But let me cut to the bottom line. You want the Core 2 Duo.

Thanks, Hopfully this is the ladt question: When I am reading reviews or specs on different processors it will say somthing like Intel P8654 2.5Ghz rated at 4.6Ghz


What does this "rated mean and how can i find it out?


Thanks for you're patience

Sorry, example please.

In reply to: Re4:

I'm sure some marketing weasel will try to flog dual core CPUs such as "Our 2.4GHz Dual Core CPU is just like a 4.3GHz CPU" or other advert rewrite, but it's not as simple as that.

In reply to: Sorry, example please.

Oh, Sorry about that I think I should have asked a question to clarify for myself what I was saying, So. This is the part where I get confused. System requirments for a video game will say e.g. 2.8 GHz prosseor speed. So does this mean that the E6700 Dual Core 2.6GHz will not beable to run this game?

Just forget the other question.

Thanks

It will be fine. Here's why.

In reply to: RE:

The GHz ratings you see on games are for the old Pentium 4 GHz which you've discovered is where the Core 2 Duo machines run just as fast as their old P4 machines at 1/2 the clock rate.

Bob

Ok
by sfig1st / March 5, 2007 7:29 AM PST

So a Dual Core at 2.2GHz and a Pentium 4 at 4.4Ghz would be the same?

No. It's not exactly 2 to 1. Here's another comparison link

.., I don't really know much about processors and clock speed's etc. and I'm starting to get confused. So when I read the comparisons on that site I really don't understand much...

System Requirment

Another Question... when a system requirment for the CPU speed says somthing like 1.7GHz is that the clock speed or somthing else?

"when a system requirment for the CPU speed says somthing like 1.7GHz is that the clock speed or somthing else?"

For now, today, that GHz number applies to P4 clock rates. The Centrino, Core Duo, and Core 2 Duo are more efficient so any known Centrino, Core Duo, and Core 2 Duo will handily meet that number.

Ok, Thanks for all this help. I have one more question and it is quite simple too. I am deciding between the Ati Core2Duo E6600 2.4GHz which has front side bus speed of 1066MHz and a Intel P4-960 Dual Core (which I think is a Pentium D) with a front bus speed of 800 MHz. So ive come to conclusion that the Intel P4-960 is better but should I buy the newer dual core anyway?


Thanks.

That P4 even at 3.6 GHz should be bested by the Core 2 Duo
by R. Proffitt Forum moderator / March 5, 2007 9:43 PM PST
In reply to: Re:

Not only in benchmarks but power consumption. The P4 is mainly for those that want a familiar CPU moniker as I see no reason for it being offered today.

I use the lawnmower analogy

"Another Question... when a system requirment for the CPU speed says somthing like 1.7GHz is that the clock speed or somthing else?"

P4 ANALOGY:

Mowing your lawn with takes a certain amount of time when you walk behind your mower. If you walk faster behind your lawnmower, your lawn gets mowed faster. Intel P4 CPUs started at 1.3GHz and there were faster models produced (1.4, 1.7, 2.0, 3.0, 3.4GHz to name a few). At the time, game makers released their titles based on performance with P4 computers, and they determined that, say, a 1.7GHz P4 is the minimum for a particular game title to work properly.

CORE 2 DUO ANALOGY:

You now mow your lawn with a new mower having a wider cutting deck and longer blade (different CPU core). You can now walk slowly behind your new mower (slower clock speed) yet cut the same amount of grass as if you were running behind your old mower (overall performance is better). On top of that, every time you mow your lawn, your neighbor shows up and walks beside you with his new lawnmower which is the same as yours (two lawnmowers = dual core CPU). You have a great neighbor!

DISCLAIMER: There are no perfect analogies.

Bob had it covered before I jumped in. Being surrounded by snow here, I just had an itch to cut some grass. Happy

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
