27" 2013 BTO - Arrived, Performance & Observations

Maybe an app that tracks the core speed while you are using heavy task will tell us the maximum speed

This would be nice. I did find the following on a forum:

"So to summarize:
MSI GTX 680M: 720MHz Baseclock >> 771MHz Turbo clock.
GTX 780M: 771MHz Baseclock >> 797MHz Turbo clock. 800MHz+ GPU Boost 2.0 clocks."

So from that, I assume that the normal 780m is 771Mhz base, and the 823Mhz that notebookcheck states is the maximum GPU boost 2.0 speed.

If the baseclock of the iMac 780m is 787Mhz, I'd be interested to see what the turboclock, and the Boost2.0 clocks are.

According the Nvidia's site, it's supposed to be clocked at 823 + boost:

Ahh... so according to Nvidia, the iMac version is heavily downclocked?

This seems odd, as the 2012 iMac had an *upgraded* version of the 680mx in the iMac.

So far people have been estimating that the new 780m was about 10% or so better than the 680mx, but I assume that was based on the standard specifications. If the iMac 780 has been downclocked, wouldnt that mean it wasn't any better than the 680?

In fact... wouldnt it mean that there would be very little difference between the 780 and the 775?

Something to test out anyway I'm sure. Hopefully this is all wrong, and the 780 is actually better than that benchmark stated.

Wouldn't it also mean there is more room to over-clock than previously thought?

I ran the test with other things open if they makes a difference.

I dont really understand the tests as such but could the chip be in a low power state as i wasn't gaming or doing anything other than static desktop stuff.

Possibly, this would be a question for the experts, I'd be curious myself.

I dont actually own an iMac yet, I have my money ready and im trying to decide between a hackintosh+monitor or an iMac. iMac is about £500 more, and has less storage, but is a nice all-in-one bit of kit.

Tough decision!

So yeh I'd be curious about how good the new iMac really is, especially the 780m.

Be nice to see some game benchmarks (framerate tests on full settings) to see how the FPS compares to the old 680mx

I was initially surprised by your geekbench score, but then realized you got the i5. I don't understand why anybody wouldn't upgrade to the i7. Last years i5 27" was a 10,643, about 500 less than yours, so that makes sense now.

Last years i7 was a 13,772.

I'm not so sure about this... according to some sources, the clock speed of a standard 780m is 771mhz (with boost up to 797).

BUT
On notebookcheck (and a couple other places) the clock speed is stated as being 823mhz. Which is faster than the iMac one.

Strange?
Click to expand...

NVIDIA doesn't specify clock speed sometimes and many computer manufacturers choose the clock speed themselves.

Apple has a tradition of not following NVIDIA/AMD's suggested frequency. For instance, the GT 650M in the rMBP are slightly overclocked compared to other notebooks.
 
So the new iMac still uses the same screen as the 2012 ones, judging by the yellow top corner glows still evident. I think every screen I've seen of the 2012 iMac had yellow glows on the top corners and some light blue/gray glow on the bottom corners. So is this a feature of an IPS panel? :confused:
 
Mine arrived an hour or so ago - it's amazing!

It's the 27" guy, fully loaded.

Tell you what, it made me awfully nervous dropping in the 16GB of Crucial RAM to make it 32 total - that's an awfully snug fit...

Anyway! No screen bleed as far as I can tell - in a not very brightly lit room - more than good enough for me. Goodness, this thing is gigantic...

Oh yeah, and assembled in USA. :)

+5fps on diablo 3 vs the 680mx.

Though I guess that game doesnt take advantage of the 4gb vram. Still, not much of a leap forward.

"the OctaneRender results for it were slower than the 2012 iMac with the 680MX as well as the 2013 iMac with the 775M".
I think that test or or that iMac had a problem. Maybe the test. Infact the 775 has been the faster. :confused:

Definitely, definitely spend the extra money on the iMac, it's more than worth it. The overall experience of ownership as a whole package is simply unbeatable.

Building a Hackintosh is stressful, running and living with it every day is very, very stressful - you keep having to worrying about software updates completely bricking/ruining your system, will my hardware be compatiable? etc etc.

I made the decision to build a powerful beautiful totally silent at full load Haswell Hackintosh because i couldnt afford the ridiculous apple prices and running great no stress at all you only need some patient and knowledge in the beginning of setup until now never experience a single problem.

I'm not sure how you managed it for much less than "ridiculous prices"...

My haswell hackintosh build, with a gtx 670, priced up at around £1150. And that was without a monitor, so £1600 total if I get a 1440p.

iMac with an i7, 256gb SSD, and a 780m, totals £1960 (i get a discount).

though the hackintosh does have 3tb more storage and a better graphics card for the £300 saving. Also takes up a lot more room though, and has almost zero resale value.

I'm still in the decision stage though. I could always get a smaller, cheaper monitor and save some money.
 
Is anyone else bored with the "My Hackintosh is better than your Mac" posts? Can't we start a new forum section or something so these guys can go talk about how their kit car with the Ferrari sticker on the hood is better than someone's 599?

I mean, I get it. I do. And I'm really happy for you. I really am. But it ruins everyone else's good time. These guys are in this thread to celibrate the arrival of their new iMacs. Then along comes Buzzkillington to tell them they made a bad decision and could have had a Hackintosh if only they were smart enough or technically savvy enough to piece together the perfect machine and then violate Apple's EULA to turn a run of the mill PC into a magical unicorn Hackintosh.

I'm with you here. And this is coming from someone who's played around with (and generally enjoyed the experience of building) a Hackintosh.

Why is that dude?people must know all their options not go buy like sheeps and apple make billions.I am an iMac owner myself i have paid it 2500 euros and still running strong and was the best computer i own but seasons are changing.Have a nice day.
 
I have had mine about 15 hours and it is wonderful. I moved up from a '07 24" 2.8 to the 27" 3.5 and could not be happier. I expect the impression of speed will increase for a while as the Fusion drive "learns".

Great point, especially on the resale value. I think many of the "hackintosh" guys on forums haven't actually built their own machine. I remember when I built my first gaming PC years ago, I was surprised how much it cost, and I did it more for the experience and less to save money anyway. I haven't priced out individual components in quite awhile, but the price difference you mention hardly seems worth the hassle. I get doing it for the sake of doing it, but to act like you're somehow more enlightened and price savvy than people buying an iMac or Mac Pro is ridiculous.
 
Nirurin said:
Whereas my 4 year old iMac can be sold for somewhere between $500 and $1000 (depending on how much effort I want to put in to it.)

I don't think a hackentosh is as cost effective as people think they are unless you need something really outsized like a Mac Pro replacement. I also don't care to have to worry about what software updates might not work right by sticking with a real Mac.

Hard Drives is what makes a computer slow. Fusion drive is not going to fix a mechanical drive getting much slower after a few years.


You have. YOU have to go SSD. I too would have picked i5 and SSD over i7 and Fusion. mechanical harddrives are designed geniusly to become slower gradually and force consumers to go out and buy new computer. ram or cpu does not become slow. A harddrive does.
