any one with Core 2 Duo 3.06 Ghz and ATI Radeon HD 4670 256MB post the geekbench score and summary?
You should be able to refer to the previously posted E7600 score. Though if it's based on the 9400M G model the memory scores should be a little lower.

I get about 6100 in Geekbench here under Windows 7. I'll admit I'm running my RAM at really high latencies though.
 
Holy Crap! From the Geekbench site:
The iMac (Late 2009) Intel Core 2 Duo E7600 3.06 GHz (2 cores) = 4297

Yippee!!!! :)

I'm not too sure how seriously I can take geekbench scores.

On the same machine, Windows 7 64 bit running 32 bit geekbench scored 6603.

In OS X, 32 bit geekbench scores 7828. 64 bit scores 8812. This is in 10.5.8.

My hardware is a Q9550 @ 3.71 GHz, 4 GB of DDR2 RAM @ 1156 MHz.

Just strange to me.
 
She can check by just going to System Profiler. the device id of the 4850 mobile card is 0x944a.
 
Hi Carressa! Thanks for sharing with us those great photos and benchmark info! Just a question.

Have you started using your iMac with programs that really works the CPU like browsing flash or watching hi-res video? How is the temperature of your iMac, does it get hot under stress?

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.

great now we need to know the CPU model whether Core i5 750 or not.


It is the Core i5.

Booo bad news. That is not what I hoped for. :( Oh well.
 
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. :)
 
she loaded it up with all sorts of intensive apps at same time and the cpu temp never got above 50 c, so that's very good.

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?

Difference:

Did you happen to notice what the fan speeds were?

The problem is specific to audio/visual based applications though. Everything else is fine. But 1% CPU utilization shouldn't result in 67C. :eek:

100% on all cores, Yes. ;) 67C is the max temp stated by Intel at stock settings. They can actually get hotter than that and survive (100C or so), but it's dangerous to the processor/s. And it's showing up on Single Processor and Dual Processor based '09 MP systems. :(

From the information available, it's software. But we've been waiting for the Nehalem based iMac owners to report in with systems to prove it. So far, Apple's not acknowledged the issue (formally), though it's been reported. We're hoping that if it does what we think (affects all the Nehalem systems), the added weight of the i5 & i7 iMac owners will force Apple to address it.

It's been there from 10.6.0, and 10.6.2 just released. No solution as of yet. :rolleyes: :(

I think my i7 with 8GB should do rather better don't you ;)

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.
