The 3.6GHz BTO option for the low-end 27" is only a dual-core but has hyperthreading while the 2.8GHz in the high-end 27" is a quad-core but doesn't have hyperthreading. Both CPUs can execute four threads at once, but which one's faster??

I just got a second Macbook Air that is Rev A SSD (instead of Rev B... But at least screen is flawless...) And since I still have HDD Rev A at hand as well, if anyone is interested in asking me to do some kind of benchmark one wants to try, now is the time. (I usually don't do much of these stuff, so tell me exactly how I can do it.)
I wouldn't be holding the HDD in about 5 days, so, I can only do it in those days.
So far I like the app icon only bounce once for most of the app's initial launch.
I noticed that this hasnt been asked on any thread as everyone is too busy debating on 3.2GHz vs. the 3.3GHz 6 core models.

Barely faster? Twice as fast? 10 times faster? Light years faster?
I couldnt find any tests so if you have input or test links let me know!

View 8 Replies View RelatedI acquired an iMac G5 17" from a friend but it's missing the software. When I turn the computer on it gets stuck at this screen with a folder icon with a blinking question mark in the middle of it. What software originally came with the iMac G5 and is it possible to get that still? Or can I install a newer version of software without additional problems?

My imac will not boot past the blue screen. It crashed whilst loading a new application which I downloaded from the mac website, had to force a shutdown as it wasn't responding, and now it will not boot no matter what I try. I have searched for answers on the forums but my mac will not respond to any keyboard commands even with the installation dvd inserted. I don't get the startup chime anymore either.

All seems fine but when I try to change any settings it comes up with a password box which I obviously dont have and the guy I bought it from is not available. Its got Mac OS X v 10.6 operating system on it. Can anyone tell me how to reset the password without having the original DVD operating system disk.

ive just purchased my first iMac as above for my son as his 1st desktop. im in the process of upgrading the RAM to 2gb and looking into purchasing Leopard 10.5. could anyone advise whether there are any other 'home' upgrades i can carry out to maximise this unit's potential for online use in 2012? and whether these 2 initial upgrades should give noticeable increase in performance to warrant the spend? i do have an iPhone4 and wish to use this unit for connection via iTunes. he currently likes to play online games such as 'Minecraft' and we have found it very slow so far...the unit does have the Airport wireless card installed, no bluetooth though.

Just picked up a 24" iMac on clearance and the Internet seems to hang up and just be a bit slower in general compared to my 4yr old MBP. I can't really get a cable to it so I'm using a Belkin N1 router. Is there anything I can do to see if it's the router or possibly the iMac?

I tried asking in the local Apple store how I could upgrade my OS but the guy said they don't sell the OS upgrade anymore.
Is there anything I can do to upgrade my OS so that I can download newer versions of software like Flash or Firefox?
I have another computer (imac intel) but I really don't want to have to get rid of this one as I like it and apart from the OS issue, it still works fine.
My iMac won't get past grey screen, I've tried holding down c. I've tried holding cmd+s. I've reset my PRAM etc, I've put back in RAM it came with, and when I turn it on I just get grey screen, apple logo and the spinning thing! Updated it to new snow leopard OSX 10.6.6 and it has a DVD in the drive and I can't even get that out! What can I do?
View 12 Replies View RelatedI have put a brand new hard drive in the machine. I took off the plastic bezel to the power cord, to make sure it's plugging in all the way. I turned the computer on while watching the LED's on the logic board. All 3 stayed on, and the 4th never came on.
I have unplugged it, left it unplugged for a few minutes, plugged the cord back in while holding the power, then turned it on (forgot what that was supposed to accomplish). No change.
I have reset the PVRAM (or whatever) 3 times in a row by holding command-option-p-r until I heard 3 chimes after the initial boot. No change.
I can get into open firmware, but have no idea what I could even try in there (other than ejecting the DVD).
I hold down "C" while booting, it chimes, it goes to a blank grey background, then proceeds on to the white screen with the apple. It sits there for a few seconds, then starts spinning the circle for a while, then shuts down. I hear the optical drive spin up, but it does nothing.

I Am very interested in the New 27" Imac quad core-i7...but I'm scared.
I have read threads upon threads about the screen flickering/yellow glow and such and my question to you all is, when to buy my new imac?
I want to buy it without these problems of course.
Does anyone know when Apple will be fixing all these problems? (If they havint already)
I had a 21" 3.6 i5 with ATI 5760 512MB in my cart but they ran out of stock, so anxiously awaiitng the return.
However they also have a 27" 2.66 quad core i5 with ATI 4850 512MB for only $80 more.
I play x-plane 9, a few games in windows 7 boot camp, render videos in handbrake a few times a month.
i am looking at ram upgrade options as i am about to dive in and purchase the 27" quad core imac.i know we need to install in pairs but do the 'pairs' need to match. can i leave the 2mb pair that comes with the computer AND add a pair of 4mb giving a total of 12mb?
View 3 Replies View RelatedEvery few weeks my iMac will suddenly freeze, the screen going black or white or pink etc. The only way I can get the computer back is to hold down the power button to force a shutdown. Then after a restart everything is OK for a few more weeks. Usually it occurs when I am on the internet. I click on something and suddenly the computer is frozen. I am on OS X 10.6.8 and usually use Safari. Ironically when I opened this forum 5 minutes ago there was a similar sounding problem at the top of the list!

iMac, Mac OS X (10.6.8), FCE 4 + FCS 3 . . . Little Knowledge, Many Opinions.
I know there had been some discussions here about the new i7 quad, and before I spend my hard earned cash I wanted some last minute opinions.
I post this here in the Mac Pro forums because I figure there might likely be more FCP users...which is what my main use for my new machine will be.
I have been wanting a new unit for several months now, and have been just waiting to pull the trigger on a Mac Pro. In fact, it has gotten to be a running joke around my house with my wife and I...we can be talking about something totally non-related and I will say "I just have one word for you...OCTO!!!" Anyway, I digress.
While I simply cannot justify (or afford really) a maxed out octo, I have been considering a "fairly" maxed out quad MP. But now that the new iMac has appeared, I am having more trouble.
I am not a pro...meaning I am not paying my bills with FCP. I would characterize myself as prosumer...which describing myself really means consumer who likes nicer equipment. I do want a "respectable" machine that will handle FCP with somewhat ease.
My current video set up is an HMC150 mixed with Canon 7D. Converting to ProRes 422 (not the HQ flavor) and using things like Magic Bullet. Not doing much Motion work...mostly because I have not learned that process yet. I am currently doing it on a maxed out 2008 iMac. And so far it has not been all that bad. Ingesting is not taking long enough to bother me really...and editing is nice and smooth. The only really long times are for rendering and encoding to H.264.
So, given these facts, am I way out in left field here considering a maxed out iMac? I am sure that during the process, the render and encode times will be what taxes the machine the most. And I am not even really sure that those times would be much different on a quad MP. Octo, sure. But even then I am not sure what kind of differences we are talking about. I mean would a similarly configured octo have double performance from the quad? Would a 2 hour render or encode on an octo take 4 hours on a quad?
The other thing I am thinking is this...Even if the iMac turns out to be way less than what I would like, I am thinking I can use it for awhile (as long as I can stand it) then maybe down the road look again at the MP...say after the 6 or 12 core thing plays out. I could always use the iMac as the monitor for a MP down the road. The glossy thing is not a factor for me...it doesn't bother me at all.
In theory, will windows on virtualbox be running best on a quad or duo iMac? Right now I am doing it on a 2008 MacBook and I must say it does put a strain on the computer to the point of being annoying. I ask since in process of upgrading to iMac.

View 24 Replies View RelatedI ordered an I7 Imac, but can't get a definitive idea if the quad core will be utilized or not. If a software program like Final Cut Express is not "Quad Core Aware", is there no advantage over a Core Duo? Why would the encoding be twice as fast, but not the program?
View 2 Replies View RelatedI've decided to jump on the apple band wagon and purchase an iMac.
I'm planning on ordering the 27-inch quad core i5 but I'm wondering whether it's worth upgrading the processor or increasing the RAM - does anyone use FCS 3 and if so, would it be better to increase the RAM to 8GB+ to run more smoothly.. or does the 4GB RAM basic run fine with FCP 7 and the like?
