My Quad Core 27-inch i5 has arrived! (includes pictures and Benchmark)

pcconvert said:
Simple... 4 vs. 8 cores. I7 has 8 virtual cores. Look at other stats at geekbench - 16 cores class of its own, 8 cores too etc. Adjust for clock speed. I am guessing i7 (I have on order:) will be about the same as 2.66 quad 09 MP.

I doubt the 2.8 i7 memory bandwidth will be as good as the 2.66 xeon (twin channel vs triple) but the score should be close (taking into account 200MHz extra and lynnfield architecture on the i7)

I'm quite surprised that the i5 benchmarks posted here are so much lower than my base '09 Mac Pro. I thought the i5 and i7 architecture was basically the same, minus the hyperthreading?

But I don't think we are comparing apples to apples here. You are using the 64-bit app for the Mac Pro score and the i5 is on the 32-bit.

I would assume the i5 64-bit score would be higher?

I am throttling with dual channel (4 modules) on my '09 quad, and my geekbench score in memory performance actually went up. I don't see where there is a negligible difference.
 
Props to the OP for including the venerable 12" Powerbook in the photo!!!

Long live the 12" Powerbook!

:D

I just ran both versions on both computers again, the results weren't even worth posting here. There was only a ~100 point discrepancy, which could have been caused by a host of other things anyway.

Ugh sorry I was so busy opening up every program I had and having too much fun I forgot the fan speed :( I will tell you there was no audible change in the system.

thank you! that is stock intel CPU!!

first stock intel quad core CPU in the iMac (with out any changes for apple)
 
I just ran Geekbench on my Mac Pro without a restart and only in 32-bit mode and I would say these are some impressive iMac's but no Mac Pro.

http://browse.geekbench.ca/geekbench2/view/183105

I hope to see someone post up some info in response to nanofrogs post soon.

Could you run:
iTunes
Quicktime
Flash under Safari

Paying attention to the temps and core % utilizations for each instance?

There's an entire thread on this. These instances (and a few others related to the underlying Quicktime X code) that have caused high temps for low core usage in the Mac Pros.

It's suspected SL is the culprit, and if it is, high temps will show up on the i5 and i7 based iMacs compared to other operations of ~ the same CPU % of utilization. It's not occuring on the non-Nahalem based MP systems. But we're trying to isolate it.

Any assistance in this matter would be truly appreciated. Thanks. :)

Well that was a good question so here is what I tried to test this...
First I opened WoW and put it in windowed mode, next I opened Photoshop and then Itunes and started UP playing in HD. Next I opened up my windows VM session and then started Handbrake and had it start converting a movie...and then i'm like what else can I do so opened a few intense flash sites and started streaming some V on Hulu:) Is that good enough for stress testing? . So I checked Istat and it shows me running at 47 to 50 degrees celsius on CPU. My GPU Diode and and GPU Heatsink hit 75 celsius but everything was running smooth as can be.
Click to expand...

This is just perfect. I'm glad I just spent 2k$ on it.
Super excited... can't wait to get rid of my thinkpad :)
 
These numbers are really making me look forward to my i7. I just ran the number on my 7 year old XP box. 1435 isn't bad for a 7 year old machine but nothing compared to what I expect in the new iMac.

For fun I also ran geekbench against my 1st gen Air. 2207....

that is an impressive benchmark!

yup OP can you please test it for us? (nano's request)

also, are there any screen flickers at all?

I ran both versions on mine and saw a significant difference ~4700 (64-bit) vs. ~4200 (32-bit). 500 points is a significant difference.

Ok ran exactly as you asked for over 20 mins this is what I got.

With all running at the same time:
cpu usage never went over 7%
Temp steady at 47 to 50 celsius
Fan 938 rpm
Itunes on its own uses 23% of the total cpu usage
Crazy heavy flash no effect

Just incase I wasn't understanding correctly even run on their own no apparent change in temps or cpu usage.

I Hope that helps.

hmm. what temperatures would the CPU idle on with nothing happening? something around the 47 to 50 °C? if so, great!. if not - hmmm :(

so flash plays well? what CPU utilisation were you seeing?

we arent load testing, we are checking to see if the iMacs have the similar issue as the latest MPs do when playing music, or anything else that might use the QuickTime framework.

Oh you were looking that bug. Still, I'd like to see a load test.

Is P55 the chipset on these Core i5/i7 iMacs? It should be but I'd like to make sure.
