What do mean that gnu is 5850.....on apple website it is clearly stated that is 5750 on 2010 27" iMac i7

What I'm hearing is that Apple "rebranded" it to 5750... its actually the 5850. Don't ask why... :confused:

wait wait i dont really understand. is it that Apple named the chip another name or that we're getting a better GPU than what it says on the website? cause my refurb imac 24 im using right now said 320GB HDD but when it arrived it was 500GB. Same thing going on?
 
I think, according to the benchmarks, that the 2.93 i7 in the iMac is not as good (by about 10%) than the Sandybridge 2.8 i7.

Still, a great deal. Mine comes today. Revised benchmarks below

Well those benchmarks you can preety much throw them out the window. Since OSX is a 64 bit OS. If you want real numbers you have to go 64 bit to get more accurate numbers.

The 32 bit numbers are off, to a great degree.

I own (soon to be shipping back) a 2.8 21.8 i7 2.8 with SSD. I have now a 2.93 27 i7 with SSD.

Here are some numbers for you in 64 bit.

(This is not mine, but I am getting about the same numbers)

i7 2.93 i7 870

http://browse.geekbench.ca/geekbench2/view/428674

10844 in 64bit.

i7 2.8 i7 2600s

(again, not mine but I am getting the same numbers)

http://browse.geekbench.ca/geekbench2/view/422258

11344 in 64 bit.

That is a difference of only 500 geekbench points. What is that, 5 percent?

Yes the 2600S is faster but by very little. And we are not comparing them here right?

imac i5 2500S

http://browse.geekbench.ca/geekbench2/view/428784

8519 Pts.

That is a difference of 2300 Pts. That is a huge difference.

imac i5 2400

http://browse.geekbench.ca/geekbench2/view/427844

9351

difference of 1500 Pts.

That is not huge, but still faster.

Hyperthreading is your friend. :)

For the 2010 iMacs, Apple was using Mobility (laptop) GPUs but calling them by the name of their closest desktop equivalent. (The tight space and limited airflow in the iMacs does not allow for a desktop GPU, which are generally faster but also draw more power and emit more heat.) In this case, the actual GPU in the 2010 iMac was a Radeon Mobility 5850 (or 5850M). Instead of calling it that, Apple called it a Radeon 5750 (not "mobility," thus implying a desktop GPU), which is a close equivalent in performance to the 5850M.

For the 2011 iMacs, Apple is naming the actual GPUs used, which are once again Mobility parts. So the real comparison you want to make is a 6770M 512MB (2011) vs. a 5850M 1GB (2010). From what I can tell, these are roughly similar in performance, though the extra VRAM in the 5850M might be important for some more recent games with large textures.

It's a 5850m, that apple re-badged.
 
Geekbench

Interestingly, my 2009 Corei7 2.8 benches over 10,000 at this point.

I suspect that with the right memory and drive you can easily do 10k with the year after model or better.

My i7 2.93 clocks constantly around 10800 or better. Hit 10900 a couple of times. So it is faster than the 2.8 2009 of coarse and just a hair slower than the i7 2600S with a 500 Pts difference at 11300 pts and the king of the hill 3.4 i7 destroys everything in it's path. At 12500 pts. :eek:

This goes to show that even the i7 2009 model is the third fastest 27 Mac, still. Two years out.

Hyperthreading all the way!:)
 
I sent back a 2010 i5 2.8 (HD too noisy) and was pleased to snap up a 2010 i7 2.93 with 256 GB SSD this week. Set it up today and found happily it came with 2 x 4GB RAM installed to which I added another 2 x 4GB I'd purchased from Crucial for the i5. Both machines refurbs.

The screen is a little yellow. I know I should speak directly to Apple UK but does anyone here know if refurbs are eligible to be sent back for a screen repair/replacement? I don't want to lose this machine.
 
Hi all,

Finally got my new (i mean refurbished) iMac 27" i7 2.93...I simply love this machine....This is my first Mac.

But I am surprised to see that it came with 8GB of RAM where as the one I ordered was 4GB....I don't mind extra RAM:)

But want to check with other people what they are getting in terms of RAM.

Yes, you can send a refurb back for replacement. However, chances are you are going to get another yellow screen seeing as this seems to be the biggest reason people return iMacs and Apple doesn't replace the screens. This is why I won't buy a refurb iMac. I bought one last year and after 2 replacements I gave up and got a refund.

I got my refurbished imac yesterday and I didn't notice any Yellow screen issue.....I played with it last night for few hours and screen looks great.....I will take a closer look again and probably run the screen test as suggested on this forum.

So I am not the only one who received the machine with 8GB of RAM :). I am prety much satisfied with the machine but the DVD drive was making lot of noice when I was trying to install couple of softwares....is this normal :confused:

The second issue i noticed is that it was very hot at the top back side of the screen (the aluminium part)

Other than these two things there was no issuess....atleast so far.;)

I though the DVD drive was quieter than the 2007 24" I have downstairs. Is your "making a lot of noise" in comparison with another machine or simply more than what you had anticipated?

I shouldn't worry about the temperature of the machine's exterior. I add SMC Fan Control to keep an eye on the temp internally - http://www.conscius.de/smcfancontrol_2_2_2.zip

I think once you've grown tired of hugging it, you shouldn't find it an issue any more! [Does the wi-fi signal deteriorate when you squeeze it too hard?] :p

Yes, it is very loud compare to my 3 year old window machine. I will test it today again with other DVDs......do you think I should return this if it is still loud or is this normal with iMacs :(
 
Anyone know if the yellow screen would be replaced/fixed at a local applestore?

Yes they replace the screens. Depends on how bad the yellowing is. Three posters in this thread alone got flawless refurbs and myself also. My 2010 refurb is in better shape than my 27 2011 with SSD model. It has a yellow screen and a few stuck pixels.

My 2.93 i7 27 with SSD is flawless. You are more likely to get a refurb BTO without any issues than a regular refurb. All the refurbs BTO I got up until now were flawless, including my current one. And all were built in the USA. I don't know if that has something to do with it or not. But my current imac 2.93 27 is the most flawless refurb or imac new or not I ever got and I got 16 of them over the last two years most for my business and a few for my home.

You are more likely to get a better refurb without yellowing issues than a new one since the refurbs get checked out more throughly.

Just check the new 2011 imac yellowing screen thread.
 
i think i got a problem machine...my hard drive is also make popcorn (grumbling) sound. A quick google search showed me that I am not the only one, there are lot of other people who have this issue, where they have returned one, two or even three machines without resolving their issue....I am not sure what to do.

Just want to ask if other people who ordered refurbished or even new mac have similar issues.
 
I am probably gonna go ahead and buy a refurb today. I was debating on 2010 top of the line 27" 2.93 i7 refurb or 2011 27" 3.4 i7 with 2gb video ram. Both with 1tb hard drives and applecare.

I have a friend who works at mac and is gonna get me a discount which would be greater on the new imac, but I am trying to budget somewhat so the total price shipped would be $1735 with applecare for the 2010. I think the 2011 was $500+. I don't see much reason to spend that much more.

Just confirming that I am getting what's right for me. I really need to reorganize my photos (around 50000+) via iphoto or aperture and my 1.4ghz G4 macmini is a little too slow for much nowadays (6 years on almost nonstop). I would be able to use a PS3 via the display port on the 2010 I assume also? Not really gonna be gaming much, I will be using it for photos and video editing mostly. My netbook has been my primary computer and I used to sort my photos via iphoto, but now they are just scattered since I have too many.

Any thoughts? I think I am probably good to go.
 
Apple are making me change to i5 3.1Ghz

I had a problematic iMac i5 2.8Ghz end of line purchased early June - Apple wanted the ReSeller to change it, but in the end agreed the problem was theirs.

I tried to swing it to get the 2.93 i7 refurb due to the fact you can play an xBox off it - Apple would have none of this and are exchanging for the i5 3.1Ghz and supplying it with 12G of RAM as per my 2010 model.

What do I do, I already have the i7 3.4Ghz with 2Gig or VRAM - will not upgrade HDD as waiting for 3T prices to fall a bit and then upgrade at Apple Authorised repair centre for about US$25 bucks.

Tempted to go BTO route again though as these machines seem in better working order than the regular off the shelf units - not sure if I really need two i7 27 inchers though - will probably take one back to UK Xmas time, and fingers crossed, get a 2010 refurb or low end 27in 2011 job as its replacement.

I'm stuck on the 27in screen though - much better than the 21.5in late 2009 iMacs I had - hopefully, they'll last a good three to four years, which will give me enough time to save for their replacements - ideally, Apple should bring out a 32in iMac with a TV card and HDMI and really make it both a media centre and high end workstation.
 
What does the imac usually ship with? I may just get an extra 8gb for now. Hoping for a fluke with extra memory or an upgraded hard drive.

I ordered my imac around 230 and got my shipping confirmation by 5.
