iMac 1.8 Ghz G5 Benchmarks

[TheGimp]

Crappy sound card,eh? Take a look at this:

http://developer.apple.com/document...cG5/03_Input-Output/chapter_4_section_15.html

Quote from Apple's Developer Connection:

"The sound circuitry and audio device drivers support audio data in multiple formats. Both digital and analog outputs support PCM audio at 16 and 24 bits with sample rates of 32.000 KHz, 44.100 KHz, 48.000 KHz, 64.000 KHz, 88.200 KHz and 96.000 KHz. In addition, the Digital Output also supports AC3 audio at 16 bits with sample rates of 32.000 KHz, 44.100 KHz, 48.000 KHz, 64.000 KHz, 88.200 KHz and 96.000 KHz."


No Macintosh has ever had 24bit 96Khz capability before. I'd say the iMac was made for audio apps.

You're absolutely right! It looks like the new iMac will be the first consumer machine to be able to take full advantage of virtual instrument libraries like the spectacular 24 bit Eastwest Bosendorfer 290 Grand Piano. I use this all the time on my G5 DP 2.5GB (soon to be 4.5GB), and my girlfriend (who owns a real baby grand) just *dies* everytime she comes over to my place. That app alone will get her to buy an iMac to use with her Yamaha digital piano so that she can go to heaven on a regular basis, if what you say about the 24/96 capabilities of the iMac is true.

Still, the iMacs could have used a *smidgen* more ram. Like I wrote, a little extra on the motherboard, and two empty slots.

HIGHLY inaccurate results

The results of these tests depends GREATLY on what your Energy Star settings are for the CPU. The following are my scores for my new 1.6Ghz iMac. (They were dramatically lower before I set the CPU to High instead of Auto)

[Uragon]

I have indeed, thanks everyone.

So the question that remains to me is, would the matched pair of 512's be an advantage over the unmatched 256 + 1 gig?

would an extra quarter gig be more or less important than the matching issue

I checked with one of Apple's reseller, and he suggested that a pair 512 is better and will be cheaper than 1 gig + 512, though he reminded that this is his personal "opinion" only.

Latency speed

Can someone with a new iMac check the CAS of Apple installed ram in the system profiler for me? Just go open the system profiler, select "memory" on the left pane, and select one of the Apple installed dimms on the right pane. It should say the speed in the lower pane. My iBook, for example, says "Speed: PC133-333" for the aftermarket dimm that I installed, which I think means it has a CAS of 3-3-3. Thanks in advance!

Plan and simple xBench CAN NOT be used as a benchmarking tool. It is an extremely outdated program that in my honest opinion can not accomplish what it is intended for, Benchmarking. It is a toy, not a reliable tool. It clearly does not benchmark G5's correctly. If you further compare the results of the G4 towers, like the DP 1.42 GHz and the G5 Towers you will see very unexpected results in the CPU test. The program clearly does not accuratly benchmark the difference in CPU performance between G5's and G4's and actually favors the G4 processors on the CPU tests. It has been admitted by the programmer in the discission forum that xBench will not test Dual Processor performance, so it can not be used to benchmark performance differences between single and dual processor systems. You will also see in the results comparison site, that it also does nopt benchmark graphics card performance correctly. This opinion is re-iterated on several other sites that commonly post performance results. You will actually see higher scores using a Gforce 4MX than you will with an ATI 9800 Pro in the same persons machine. No other benchmerking tool would give you those results. I've also read people getting lower scores with the ATI 9200 then with an ATI Rage 128. There are many more examples of how poorly xBench actually benchmarks performance on the results comparison site and in the xBench discussion forum, however he usually does not respond to threads regarding the lack of functionality any more. Xbench has not been updated in almost a year, and in my opinion never ran correctly then either. I truely think the programmer has lost interest, however in the thread where he admitted that xBench does not benchmark dual processor performance, he did mention that you could donate money and mark it for upgrading the program. Again xBench CAN NOT be used to benchmark systems as it is. Maybe it would become a useful tool if it ever gets updated. However, I would hold your breath. I really think that xBench is a dead product, and probably will not see an upgrade.

I agree with you on that. Especially the Xbench CPU test sucks. It does well on RAM and HD testing, but the graphics test doesn't do very well either.
The idea is good, but lack of upgrades, probably because lack of money?
I like the graphics test idea, though. It has a separate window that has the same resolution, no matter what your screen resolution is.
Also, the results on the same machine with same specs may vary quite much, I have usually rebooted again to get better results.
Cinebech, then, isn't the best choice either, but is okay in testing CPU speed between different Macs, but it runs faster on PCs, because its been "optimized" more for them, and uses floating point operations, which I've heard P4's are good in. In testing graphics acceleration, it's the best benchmark apart from real world tests out there.
Of course, all this is based on my humble opinions, but this is what i think.

 

[chazmox]

Visited the Apple store today and ran Xbench on a 1.6 iMac G5 with 1 Gig of ram. I got an astondingly low 105-109 ( I ran twice ). I ran Xbench on a 12 inch PB ( 1.33 G4 and 256M of RAM ) and got 95.

I quit all apps but the Apple store usually have stuff running in the background, but I was still surprised at how low the scores were for the iMac G5.

I know that XBench isn't the greatest, but it is the most widely used tool and does split it's scores out so you can see which criteria has the most impact ( FP was very good on the G5 as expected ).

I tried to find any energy setting, but couldn't find one for the processor but the Energy Saver settings offered the same options as I have for my iMac G4...

Based on others' reports, I would say that it safe to assume that if you had turned the processor setting to highest, the iMac would have done much better. The Processor Performance setting is under the Energy Saver preference pane in System Preferences. It is under the "Options" tab. The ability to change the setting is unavailable on the computers in the Apple Stores, however, unless you know the administrator password. You would need to convince an employee to change the setting for you.

 

[mizzman36]

I popped in to my local Apple Store yesterday ran xBench on a DP 2.0G PM G5 with 512 RAM and a 1.8G iMac with 256 RAM.

I shut all running programs and set processor to "Highest". Results were:

PM: 216
iMac: 153

Unfortunately top in OS X doesn't support the F keystroke

Only platform where I have gotten that to work is Linux...

Bugger. Bugger bugger bugger. I posted that when I didn't have access to my PowerBook, so I assumed that what worked for top on one platform would work for top on another. Excuse me whilst I quietly take my foot out of my mouth and check on my PowerBook... *trudge trudge trudge* (five or ten minutes later) Okay, you're right -- it doesn't support the F (or the equivalent O) keystroke. However, if you fire up top with the command "top -o -vsize", the end result is the same.

Nyah.

(man top is your friend. )

 

[IBSNOWEDIN]

Can't wait to get mine still havn't got the e-mail on shipping, but as soon as i get it i'm going to pop 2gb of ram in it that i just got and do a benchmark on it and post it up to see what the imac can do whne it is maxed up.

 

[stevesien]

So we have the iMac G5 scoring 134 with 256MB Ram and the Original single G5 1.8 w Radeon 9800 SE, 1.5GB ram scoring 124.

Based on that info, regardless of Xbench's qualities, we must conclude that the iMac is a very quick machine in comparison.

The ability to change the setting is unavailable on the computers in the Apple Stores, however, unless you know the administrator password. You would need to convince an employee to change the setting for you.

I saw the lock on for admin privledges and knew I couldn't change anything - but I swear I did not see that processor selection pull down - I looked so I could note what the processor performance was set at. Maybe I missed it, but I did look in each tab of energy saver...

My 15" PB G4 at 1.25 gets around 118-120. I've compared a few scores and many places the G5 does better ( memory and drive access the G5 does worse? ) but it still gets a equal or lessor score...

 

[Telomar]

One of the big problems with Xbench is the way it weights things to get its final number. In a lot of respects those weightings don't match with what is most important to performance. I also have some serious questions over some of the subtests. Too much variation in general though for it to be useful.

 

[ki-goi]

wow, the xbench hard drive measurements are very unpredictable. they seem to be the thing that's turning all the numbers upside down. oops has that already been said?

anyway i expected any given imac to have lower relative hard drive performance compared to pro machines. these numbers though are very strange, what does it mean that a single computer's hard drive throughput varies as much as 2x from test to test? activity in the background?

what's good software for hard drive testing... somebody should do that.

[edit] i ran xbench on my 550MHz G4. the brains and graphics results were nearly constant, the random disk test results were nearly constant, and the sequential read tests were all over the place - but, this ATA-33 machine's disk scores beat some of the posted SATA imac scores - 64 overall, 55 sequential, 76 random. why is the imac slower.

 

[mrzippy]

Hard Drive Speed

Maybe I have missed this in this very long thread, but has the poor speed of the hard drive been discussed?

Considering it's supposed to be a Serial ATA drive with an 8mb buffer why are the benchmarks so poor.

I am looking to replace my PM Dual 1.25 (FW800) + 15" TFT with an iMac 20" but the HDD benchmark are really putting me off.

Just done some benchmarks below, they seem to be way lower than the last time I did them, maybe a bug in OS X 10.3.5 ? Otherwise the iMac HDD would seem to be better than mine

hard drive speed - sorry!

i don't want to be accused of FUD - there was only one test quoted in this thread that was worse than my ATA/33 G4:

Disk Test 48.64 - Sequential 46.86 - Random 50.56

the rest of the imac results were around the same place, all scores beating my older computer:

Disk Test 79.19 - Sequential 67.00 - Random 96.82
Disk Test 93.76 - Sequential 86.24 - Random 102.70
Disk Test 92.47 - Sequential 87.38 - Random 98.20
Disk Test 86.15 - Sequential 77.71 - Random 96.65
Disk Test 84.10 - Sequential 98.22 - Random 73.54

i found on my computer that xbench's random test is more reliable, and this seems to be true here, too. for the imac, the range of sequential results (67.00-98.22, tossing the very low one) is more variable than the random results (73.54-102.7, again tossing that low one).

it looks like the new imac will regularly score above 96 on the random test, maybe that's how to use xbench to look at drive performance. it's certainly better than my computer's repeated 76 score.

[edit] i changed some stuff above... none of the numbers... just making it point blank clear.

 

[punkmac]

upgrade a 1.6 combo?

Has anyone thought of upgrading a 1.6 combo model with a dual layer Superdrive and third party 250 gig HD?

I feel Apple knows we are going to ditch the stock RAM anyway so why not keep it at the lowest possible. I would rather throw away 256 not 512.

Just wondering...

G5 iMac 20" vs. New 20" Cinema display

Why do i have the gut feeling that the iMac LCDs are not even close to the new Apple Cinema displays? I'm thinking they are probably either the old 20" or the same ones as the original G4 iMac line.



millions doesn't inspire much confidence for me -_-

**********************************

Well, the dot pitch works out the same for both.

{ {20cos[arctan (10/16)]}•(25.4) } ÷ (1680 ) = 2.58 mm

This is what is also posted for the Cinema 20".

But I could find nothing for iMac's response time to compare with Cinema's 16 ms.

"Ah ha! Thanks. A quick Google reveals this link. So this memory module is made by Crucial:

Thank you! That confirms my suspicion that iMacs are shipping with CL3 memory. Now I can go ahead and order another 512mb CL3 and it should (fingers crossed) be considered a match with the one installed by Apple.

Tested a G5 iMac/1.8/512MB at the Apple Store today!

1) FYI - Cinebench for G5 is beta. Some optimizations missing.
2) I didn't have an admin password to change the Energy Saver from Automatic to Highest Performance on the iMac G5.
3) Aluminum Powerbook is my personal machine tested at home (Energy Save set to Highest Performance)

Any testing with iDVD or DVD SP?

Just curious if anyone's been able to do a non-scientific test with regard to the iMac G5's performance of iDVD encoding: if so,

How long does it take in reference to the length of the movie?

Do the fans spool up and get noisy?

With regard to the displays: Any major problems with burnt or stuck pixels?

Why should someone use such Energy Saver settings in a *desktop* computer anyway?

To do our bit to help save the planet.

Now that i've expressed my dissapointed state, i'd also like to say that other than the GPU, i believe this to be a well priced and zippy consumer level mac. I just can't get over the fact that this can't even run Halo.

Halo blows anyway

Halo blows anyway

It may either suck or blow... dunno, havn't played it

But I'd say the requirements for Halo are WELL BELOW that the iMac G5 so I guess that dude is just trolling....
