27" 2013 BTO - Arrived, Performance & Observations

My BTO 2013 Haswell iMac turned up this morning. Love it, here are some performance stats and observations.

27" 2013 iMac
Haswell 3.4Ghz i5
16GB Ram
780m GPU
256SSD





SSD

Black Magic speed test


Boot time to desktop = 14.48s
Shut down to screen off = 6.14s


Geekbench

I only have the tryout version so 32bit only.

Single Core =3493
Multi-core =11042

GB page here : http://browser.primatelabs.com/geekbench3/96605


Cinebench 11.15

CPU = 6.13 pts


GPU =55.36 fps



Power consumption

Amazing, quite unbelievable

Off standby = 1Watt

Idle desktop = 30Watt




Screen bleed

Hardly any, slight bleed from the corners but well within acceptable range, not even noticeable unless you are looking in unrealistic circumstances or very odd angles. I can notice a yellow cast if i put my head on the desktop and look up to the top left. Which is frankly ridiculous

Just over half brightness - which was boosted from auto sensing which put it at just under half brightness.



Pictures taken with 5s so low noise - I think the noise of phone sensors probably exaggerated the issue as noise is colour tinted.


Other observations

Fan made no noticeable change in speed or volume as it was running the benchmarking tests. It is hardly noticeably, it isnt inaudible like my MBA but its still very quiet.


Hope everyone else is happy with their 27" iMacs. I know people are worried about their screens with bleed and casting, mine is showing no concerning signs.

Enjoy!

Sunspider browser benchmarking is indecently quick

Everything feels instant

There is no point trying to benchmark opening programs like iPhoto - its under a second from fully closed.

Thanks guys glad some of you found it useful

SSD is now 5% faster after installing some of my apps

Read : 740MB/Sec
Write : 680MB/Sec

So yes pretty insane!


I noticed that cinebench issue too, perhaps its not correctly reporting the Haswell chips, i tried to get the latest download of it.

Power consumption monitoring is off now but at idle desktop / reading web pages it ranges from 25 watts min screen brightness to 70w max brightness. That is damm impressive.


And yes my screen bleed test did have major reflections, there is a window to the left of the iMac shining on the glossy desk but very pleased with screen.

With most of my apps installed i only used 19GB of space! - i think it would be a different story if i stored my photos on the internal drive of which i have over 200GB. I also have 400GB of music but its all itunes matched now. My photos will live on my external drive when it turns up. I anticipate my Aperture cache and meta data to be around 30GB on the SSD.

Memory : i opted for factory 16GB. I know many of you will install it yourself but its good to know Apple installed 2x 8GB so i'm free to install a further 16GB kit if i wish. So no wasted sticks.

I like the hue those lamps give off in the evening. Nice warm temperature



I am happy to do gaming benches, however do you actually mean in game benches or is there a program i can use?

I dont have bootcamp set up yet, i dont have a copy of windows (it has been a while). But i am planning on setting bootcamp / windows up for some gaming in the near future. I'm sure you will have yours by the time i get around to it.
