New iMac

Anonymous
Not applicable
Hi:

The new iMacs finally came out and while a not a huge upgrade it's
time to get a new one.

I plan to get the 27"5k with:

-4.0ghz i7 +$250.00
-Add my own memory ?
-AMD Radeon R9 M395X 4gig video +$250.00

-3tb Fusion +$100.00
OR 512 GB SSD +$200.00

The 1TB SSD is too expensive for me: +700.00

For how ArchiCad works, I really don't know if the Fusion drive is ok, or is the 512 SSD that much better. If I go with the 512GB SSD I would need an external drive which is ok I guess, but since I take it client meetings a lot it would be one more thing to fuss with.

I do mostly custom residential and small commercial. And how much ram to I really need.

thanks!

I would go with the 512 GB SSD and an external drive for older files etc. I just updated my old (2011) MacBook Pro to a 512 GB SSD and I notice a big difference.

I read somewhere that the new Fusion drives on these iMacs have smaller SSD capacity than they used to.

Cheers,
Gerald

I agree with Gerald on the 512 GB SSD + external HDD.
Also, I would add my own RAM to make it 32 GB. That should be plenty for the next several years. (Maybe 16 GB would also be enough but I don't like to be cheap on amount of RAM as that makes the biggest difference if you run out of it).

One other thing about the RAM. According to this article
http://9to5mac.com/2015/10/14/new-27-inch-imac-maximum-ram/
you can get 64 GB of RAM into the 27 inch iMac and Apple will only put in 32 GB. I remember when I got my MacBook Pro that you could only get 8GB installed from Apple but it actually supported 16 GB which I did on my own.

32GB might be all you need but Apple usually charges a premium for RAM so it might pay to order the minimum and upgrade yourself.

Gerald

Hi Gerald and Laszlo:

Thanks for the information! Gerald, I do remember seeing that the ssd had been lowered for the Fusion drives-I have no idea why.

Laszlo and Gerald I think I will as you suggest go with the 512 GB SSD with 32 GB of aftermarket ram. With a 512 drive I can certainly have the client files I need without dragging along another HD.

Now all I need to do, round up my loose change………..

I would also be interested in other peoples experiences with iMacs.
Good and bad!

I have a late 09 iMac and have loved it from the start.
The good: Works great in Archicad and still has plenty of horsepower.
The bad: Not upgradeable. Even though my processor is more than adequate, my video card is not. I will need a new computer soon based on v19 and beyond. (Although 6 years for a computer is not bad).

I have been managing the IT network and been the primary protagonist for maintaining a solid BIM process within our office for the lat 15 years.
We have ranged in size from 8 architects up to our current 15 architects over that time.
For that period we have used a multitude of mac products from the early power macs in 2000, the first iMac, eMac, aluminium cased powermac and for the last few years, since the advent of the 17" white iMac, we have only use iMacs.
Generally specced with 80% upgrade of ram, second best graphics card.
In all that time we only lost 3 machines to 'mechanical failure'.
We are also often taking on staff from a PC background and generally they have all been happy with the general performance of the iMac machines.
Some admittedly are now 4 years old and due for replacement. Especially the 512GB graphics card machines.
monitoring the machines performance, it is typical that machines are not running our of ram as they all typically have 16 to 20 GB each.

I have noticed a marked improvement going to fusion drives of late, but have held back on the retina displays.
Cheers,
Karl Barker.

Hi Karl:

Thanks for the information! So do you think 24 GB ram should be
enough? Need to save wherever I can,

thanks,

Don

Go with SSD and 24 GB RAM You will see the difference and it will serve you well the next 5 years

We're looking into that as well. Most of our office is 2010-2014 iMacs. However, in the last year, most of the Architects have wanted Macbook Pro's. The major drawback there is that Apple has soldered the RAM, and limited these great laptops to 16 GB (same thing with Mac Mini, plus crippled dual-core CPUs). It's ok for now, but I fear needing more in a year or two.

It seems like they are doing this to push people into getting the coffee can Mac Pro, which has seen lukewarm sales. Even though they can upgrade RAM to 128MB, everything else is pretty fixed, and there's no room for storage, more video, etc. Plus, they're expen$$$ive! In general, I think the iMac is a better value.

And don't get me started on using a Mac as a server... none of them fit the bill, and we're starting to put in Windows PCs for BIM Servers!

Hi:

Well I finally got my new 27"iMac Retina 5k, i7 4 ghz, AMD Radeon R9 M395X
512 SSD and 24 gm ram set up and I have to say its slower than I expected.

To a launch a file on my old 27" iMac 2.93, ATI Radeon HD 5750 with 8 gb of ram it takes about 1 min, but the same file on the new iMac takes about 1 min 40 sec. The file is along with AC 18 is installed on both machines.

Worse when I edit things in plan on the new machine, things seem sort of "sticky" that is there very slight delay from I move to an edge of a slab to when it shows in its new position. On the old machine the edit seems to
appear instantaneously. The 3d model appears much faster on the new machine.

Just some first observations, but I would really like to know if anyone has any ideas why the new iMac seems to function slower (in an irritating way) than the old iMac.

Any suggestions? Adjustments?

thanks,

Don

Hi:

Forgot to mention one important thing, the new iMac is El Capitan (10.11.2) and the old is Mountain Lion (10.8.5)!

thanks,

It could be from the OS version and ArchiCAD version, try installing archiCAD 19 if yo have the license for it. It is much faster than the previous version.
It CAN'T be from your hardware.

Thanks for the reply!

I have been waiting to move to AC19, but for the moment I'm still on 18.
Hoping someone else has some ideas.

Hi:

Anyone have any other thoughts on why AC18 would be so slow my new
iMac? See above for the specs,

thanks!

Don,

I recall seeing something about turning the hardware acceleration off to improve 2D draw times with certain machine configurations. You might try that to see if it helps.

Going from 2,5k (I'm assuming the old iMac had a 2560x1440 pix screen) to the 5k is possibly the culprit: to rasterise the vectors of the model requires a lot more calculation on such a high resolution, I suspect.

Try playing with the 2d antialiasing and 2d hardware acceleration settings. The model display in 2D navigation also has quite the influence on the speed.

Thanks for the replies and they did help. I searched for Archicad problems with iMac 5ks (probably what I should have done first) and found that Graphisoft has specific recommendations for AC18 and AC19.

I have AC 9 and will be shifting to that soon, so hopefully things will be better than going to a lower resolution on AC18.

Thanks again
