#26690 - 11/20/0209:02 AMG3, G4 vs. the Pentium 4?
Does anybody know if there's a difference between G3 Mhz, G4 Mhz and Pentium Mhz rates?....meaning...is Mhz standard no matter WHAT processor produces the speed?<br><br>I already have a G4 733Mhz desktop at home.<br><br>However, I'm considering getting a laptop...and I'm sorry that I'm asking about a PC comparison here but...it's coming down to:<br><br>- Apple's $999.00 iBook at G3 700 Mhz or <br>- Dell/Gateway's $999.00 Pentium 4 at over 1Ghz.<br><br><br><br><br>----<br>S3V3N<br>Washington, DC USA

Check out the presentation in this link: http://www.apple.com/g4/myth/.<br><br>But basically, the clockspeed (Hz) is the rate at which your car passes through a road per second. As it passes your drive by road signs or instructions, and the RISC or CISC are the types of instructions you read and execute in every pass.<br><br>The G3 & G4 are of the RISC family: Reduced Instruction Set Computing<br>The Pentium & x86 are of the CISC family: Complex Instruction Set Computing.<br><br>RISC is a much more efficient instruction set than CISC, so you're talking about 2 different roads with different road signs.. Did I make it more complex? <br><br>
MHZ are the same on both platforms - however, MHZ is NOT the be-all, end-all of speed. You have to consider back-side cache, IO speed, hard drive speed, RAM speed, video speed, and a host of other factors.<br><br>That being said, the Pentium 4 will be MUCH faster than the iBook - MUCH FASTER!<br><br>For a simple comparison, think of the Apple G3 the same as a Pentium 3, and the Apple G4 the same as the Pentium 4. This is not 100% accurate, but it gives you an idea of what you are comparing. Essentially, you are comparing a G4 Powerbook to a G3 iBook.<br><br>[color:red] Kiss My Banana!</font color=red><br>Visit me here!

That's a P4-M - it won't be that much faster, but it will probably be a bit faster. But will *you* be faster is the real question.<br><br>I find a better analogy is that MHz is more like RPMs or horsepower in a car engine. In different engines/cars/gear ratios, it really doesn't tell you how fast your car will go, or how well you will like driving it. ;-)<br><br>Anyway, go with the iBook, you won't be sorry.<br><br><br>

wars have been fought over this subject matter with tech heads.<br><br>there are many variables that make a system fast and Mhz is one of them. Obviously a 700Mhz G3 will be faster than a 600Mhz G3. <br><br>but... you are comparing a Windows machine to a Mac. If you already have a Mac why not stay with a Mac? Are you happy with the desktop? The iBook will be about the same speed for surfing and desktop applications like Word, Excel, etc. On battery power the iBook is a bit slower, I'm assuming that Jag shut down the disks and stuff to make the battery last longer.<br><br>The difference between G4 and G3 is most felt when using apps like PhotoShop and Final Cut Pro that take advantage of the extra capabilities of the G4 not present in the G3.<br><br><br><br>
Everyone is right.<br><br>Even more simple.<br>Do not compare mhz to machines that have different procs.<br>Macs and PCs = different procs<br>G3 to G4 = different procs<br>Pentium 3 and pentium 4 = different procs<br><br>You can compare a G4 600, 800, 1 gig same proc but a no brainer.<br>Bottom line - You can only compare mhz to chips from the same family.<br><br>Is Cisc or Risc better?<br>Depends on what you do.<br>A company that tested just the chips only - no bus, no ram, no HD, no cach, no software overhead - just the chips alone. They found that the cisc chip multiplied faster and the risc chip added faster and that was by a few nano seconds.<br><br>note; this is not 2+2=4 or 2X2 = 4 its about how the proc views the code in binary.<br><br>Example in graphics = addition - the risc or Mac would be better at that task.<br><br>
if you already have a mac and want to go for ease of use and compatibility you should probably go for the ibook. on the other hand if you want a pc besides your mac, to be more compatible with the rest of the world you might consider the pc. but than i would be quiet about that choice.<br><br>http://raszl.net
