This is the like for like replacement for my mid-2011 iMac -21.5-inch:
Specifications
2.7GHz quad-core Intel Core i5
Turbo Boost up to 3.2GHz
8GB (two 4GB) memory
1TB hard drive
Intel Iris Pro Graphics

Don't forget the HDD is 5400.

This is my current iMac -
Mid-2011
2.5 GHz i5
20 GB 1333 MHz DDR3
AMD Radeon HD 6750M 512 MB
500 gig hard drive - 7200

Have we really moved on that much in 4 years?

Please don't respond with a heap of BTO options or models higher in the range. I am comparing my model with its replacement.

----------



Well I sincerely hope you don't run your own business if you think that philosophy is the right one?

You cannot compare 20GB of RAM and 8GB of RAM. Yours is not a stock, because it only came with 4GB of RAM, but you upgraded it yourself.

The Iris Pro is leaps and bounds ahead of the Radeon 6750M. And so is the Haswell i5, compared to the Ivy Bridge i5. Geekbench scores alone will show that.

With a far faster processor and GPU, it will more than compensate the 5400rpm drive.
 
Why do people make such posts? If you are in business you should be saying - this is my product, this is what I am currently doing, what is it that I could be doing better.

Any company that makes the comparison you make is sure not going to stay in business for long.

I sort of did it to see how far ahead the iMac is compared to AIO competitors, I do see plenty of things that Apple continues to push forward, such as fast SSDs and Retina displays, plus Thunderbolt and now Thunderbolt 2, and soon to be Thunderbolt 3. I assume those are things that they are focusing on.

Apple doesn't make most of the Mac components themselves so they just pick whatever comes out of Intel, AMD, Nvidia, Samsung, etc that year. Granted, computer components these days usually only have single-digit performance gain year-by-year.

If you are content with two steps forward and one back in 4 years then you're more easily pleased than I, it's as simple as that.

----------

Depending on how you set it up you can build an iMac that is MUCH faster then your current iMac.

3.1ghz i7 Haswell is twice as fast in certain Geekbench benchmarks.
Wifi AC 5x-10x faster
USB 3 5x-10x faster
SSD again no comparison
Thunderbolt connection (not sure if yours has that or not)
Not sure what graphics card you have either but its likely slower (just saying).

I think there is a noticeable upgrade to be had.

That would hardly be like for like models which has been the nub of the argument from the get go.

So essentially speed bumps.

For the last time, stop talking like it's been 4 years between releases because it hasn't. The retina models may very well come with Fusion drive on the base model.

Yes, and what's wrong with that?
 
I can never understand why consumers are so hooked up on specs when the differences in real world use for most is not such an issue. My iMac gets the following use - Office work 75%, browsing 20% photos the remaining 5%.
So why are you considering a new iMac then?

I was just stating what the poster was trying to prove.
 
Clearly he's not, otherwise he wouldn't be trying so hard to justify his current hardware.
What is this thread about then?

For his usage scenario his hardware seems pretty perfect.
An ssd wouldn't hurt, but his 20gb RAM might compensate for the slow hdd.

I am missing the OPs point here.
 
I actually think the OP has a point tech since Sandy has been kinda ho hum. The HiDPI thing has been fun to watch but beyond that it's SOSDD.
 
I am missing the OPs point here.

From what I gather that's it, he's just trying to justify not getting an upgrade. If he's happy with his current hardware and it meets his needs that's fine, but that doesn't mean he should be on here complaining about the iMac being "stuck in a rut".

I think that one of the issues is that we see the least amount of improvement year over year in the 21.5" machine vs the 27" machine. It appears that Apple is positioning the two in different tiers based on their base configurations and their BTO options.

I bought my iMac in June 2011, so how long will that be in a few months time err! 4 years! :)

When I go to trade my four year old car in for something new I can't advise the salesmen that as that model wasn't replaced until maybe six months ago it's actually only six months old, or can I?

You have a very bizarre way of looking at things.

Speed bumps and real world performance for someone using their computer for mainly office tasks is hardly likely to make much of a difference is it?

----------

In the main I would agree with that. What Apple needs to recognise is that not everyone has either the space or the need for a 27" machine. I actually bought the 27" model before the one I have now. It was immediately apparent it was simply too big for its situation so I sent it back.

I do think what we currently have is a hiatus in the technology, so for me the way forward in the interim would be to look at ways of improving the form factor.

Quite the opposite - I was actually trying 'to justify' getting a replacement. Sadly after looking at the present model it was impossible to make out a good business case for doing so.

----------

So why are you considering a new iMac then?

Simply because it's four years old and it was struggling. That has now been sorted out, it appears the Parallels .PVM file was the issue. Now I have removed it the machine is back to how it was four years ago, nay better with the 20gigs of RAM.
 
I actually can't if looking at like for like not a different model or BTO. On the Mac side the old gal still performs really well and so it should with 20 gigs of RAM. What has been annoying me is the slow down when using Parallels with my W8.1 VM.


Sorry to dig this up - have you tried Parallels solution to "extremely slow" performance after upgrading to Yosemite?

snip.

Indeed for the price the new models don't necessarily offer a compelling reason to upgrade; this is especially true of the 21.5" where the powerful GPU options are not available. The 750m in the current models is actually pretty similar in real world use to the 6970 in the 2011 27".

Additionally the lack of even RAM upgrade option for after sale is a big deterrent.

Moore's Law doesn't work for desktops anymore. It was great while it lasted :(

Honestly I've had problems figuring out, why so many people found it important to upgrade their old computer frequently, when all they used it for was checking mail and surfing the internet.

Then the iToys came, and nowadays people upgrade their smartphones instead. If they forget to do that, the nice folks at Apple remind them by releasing a new OS, that will make their "hopelessly old" iPhones run very slow.

It's kind of the same with desktops and OSX. The solution could be not to upgrade the OS, but then the nice folks at Apple will kindly remind you by releasing software updates that demands an OS upgrade. Like FCX.

Back in the good old days, gaming was a strong force, keeping Moore's Law at it's pace. It didn't really work on Macs, but some of the technology from the PCs spilled slowly over to the Apple community. Then came the console wars.

Itoys resulted in a need for smaller components, so Apple decided to make the iMac thinner, lacking stuff that could make it run faster. It doesn't really matter how thin it is, but a lot of marketing, combined with people not thinking very well, can always fix that.

Keep your Mac, and don't upgrade the OS any more. Be happy that you're not using it for anything really demanding. There are lots of other things you could spend your $$$ on. SuperFish can help you with that.

In the meantime, we can hope for a new Jobs or Tramiel, but probably "Thomas J. Watson was right", even though he was quoted wrong.

Yes, thanks. I was one of the first to try it and whilst it helped to a degree it really wasn't a long term solution.

What I have also noticed is the noise and heat levels have dropped off a cliff since removing the PVM file. I wouldn't have believed it could have made such a difference.

I have hardly heard the platters since.

How very true and insightful. I made the mistake of upgrading my iPad 2 to iOS 8 and it's never been the same since.

Looking back I also wish I had stuck with SL, as you say though all manufacturers have ways of getting round such 'awkwardness'.

Intel says that Moore's Law will continue through 7nm

http://www.pcworld.com/article/2887275/intel-moores-law-will-continue-through-7nm-chips.html

Moore's law is about transistor count and not necessarily speed.
 
@lowendlinux

Yeah, I'm pretty much not so sure about that ;)

Furthermore more transistors normally equals higher speed.

To me the two quantum leaps in performance was 286>386 (boy, that sped up my Mandelbrot renderings considerably!), and SSD (especially raided).

I've always tried to take my computers to the max. Primarily because I thought it was fun. Nowadays I'm an amateur astronomer, and recently I've worked on something that I call "Crowd Imaging". That is basically combining giant datasets (several Terrabytes), and it's very time consuming (days or even weeks).

Therefore I tried to benchmark my old trusty 2008 Mac Pro, using a real life benchmark built into the astronomy software I use. To my astonishment even a fully spec'ed new cylindrical Mac Pro wasn't that much faster. At least not fast enough to legitimate the price tag. Mine is an 8 core Xeon (no HT), so the next generation was "twice" as fast, but since then things have pretty much been stuck.

I'm exaggerating a bit, but I honestly thought it was time for an upgrade. Instead I bought a USB3 card.

I trust that doing this means that you cannot run your virtual machine unless you keep the PVM file and restore it at a later date?

My 12c/24t 3.06 Westmere HP Z600 is within spitting distance of the newest top of the line MP. The glory days of a new processor meant huge speed improvements is long gone and so is a great deal of my love for tech. I still derive pleasure from reading about it, talking about it, and bench racing a bit but there are no mush have upgrades.
 
I think the OP is just a bored teen looking for an argument or trouble.

This thread is going nowhere. It's better if it's closed and moved off to the wasteland.

IDD, he would start a fight with Ghandi.

The thread is just going round in circles with no new information being contributed which is in breach of forum rules. Where's a mod when you need one?
