Ten days later - after somebody with a better system that is NOT overclocked, but better components overall that posts a legit time of 2:42 using 64bit software, and almost a minute LESS using 32bit software
So what got upgraded in the past 10 days to get 25 seconds FASTER in 32bit?
or what got degraded to get 10 seconds SLOWER in 64bit?
Or is it just convenient that re-running the tests put you back as the fastest in this FM poll?
You don't have to believe me but if you want a proof, I can post a video if you are willing to make it worth while for me. As for the 10 second gain from 64 bit, well I found that different add noise trials changes the run time. Since add noise is a randomized command, each time u do it, it is slightly different. There is another possible reason. The 4.3Ghz that I am getting is at bclk=206 with multiplier set to 20 with turbo on. This means the multiplier goes to 21x in almost all cases unless your cpu is being overstressed (eg. using Prime95, it goes down to 20x in 2 seconds). With this photoshop benchmark that gained 10 seconds, it could be because the ambient temperature in my room increased enough to cause throttling from 21x down to 20x (although I doubt it cuz i monitored that before and it seemed to stay at 21x).

LDbecker >> There are ways around the "locked" cpu's and they usually come from the motherboard being good. CPU multipliers have been locked for quite some years now except when you pay for the highest end ones. The way to overclock is to overclock the bus clock going into the cpu. So say a 2.0Ghz computer is made from a processor with 20x multiplier and 100Mhz bus from the motherboard. On a high end processor that is "unlocked" you can increase the multiplier. On a "locked" CPU, what you do is increase the 100Mhz bus to say 150Mhz and the cpu till multiplies it by 20x giving you 3.0Ghz overclocked speed. OCforums.com is an excellent resource. I highly suggest it before you overclock.

I certainly don't need proof. But it is obvious that this 'benchmark' is seriously flawed:
A: you've chosen a 'randomized' filter that has varying degrees of time
B: somehow, you're 32bit CS4 runs quite a bit faster than 64bit but not on other boxes.
For a "future proof" bench, it should be 64bit tuned - that is the future of computers and OS and software.
For you to get SLOWER times on a box that is FASTER than Larry's, then either you need to contact Adobe for a crippled version of 64bit software, or your benchmark is memory limited, or the capability of the Extreme processor (cache?) simply walks away on your version of a benchmark.
In ALL other benchmarks that are realistic, there is a VERY LINEAR scale per processor family based clock speed.
So obviously, there is no static benchmark comparison to be had here. It is hardware dependent, software dependent and variable in pattern.

I agree with what you are saying. I just don't see how in the world the 32 bit version runs faster than the 64 bit with a modern system running 64bit operating system. The things that comes to mind are that (a) I screwed up in the install or (b) windows7 64bit is still very much not 64bit optimized yet since it is still a release candidate that I am using.
In terms of using a randomizing function, I thought 64,000,000 pixels were enough to create a distribution that's unique AND about the same difficulty to process with filters. I was expecting a variation of <1% but instead got a variation of a few %.
I wouldn't say that is true at all. Harddrive and memory usage is pretty important. For example, in this benchmark, I scored faster times than the 4.0ghz i7 extreme on all processes that lasted a few seconds or longer, but scored slower times for processes that were short. There was a lack of linearity compared to their times. You have to realized that if you want "realistic" benchmarks as you are saying, then it is indeed supposed to be not just cpu dependent. It needs to be hardware/software dependent and depends on multiple facets of software/hardware. These realistic benchmarks are meant to test what it takes to do a process on a computer that you might actually use. For me, as I've stated above, is for testing noise reduction but since not everyone has noise reduction software, I used this. Unrealistic benchmarks are the ones often referred to as the synthetic benchmarks that are specifically tailored to test a specific hardware or software component (or a specific set of hw or sw components), and be highly independent of the other components. Maybe this is what you were looking for?
Now I kind of feel like going back the the driverheaven benchmark to see how my 32bit times compare with my 64bit times. I'm hoping it's because win7 64 is not optimized yet.
There is no doubt that Larry has a very nice system, but I would think that your 20% higher clock speed should offer more merit on the 64bit side - unless your test really is RAM limited and Larry's 12Gb takes it in stride. But that makes no sense that your 32bit times are faster
But yes, I would think that to get a general basis of how fast a box runs a test, would be more than just one filter. Yes, there are always factors to consider and some tested are tuned to take advantage of certain components. But broadening the spectrum running a realistic set of filters over static images would result in truer results.

Okay, I redid that benchmark using 64bit getting 159 seconds which is perfectly linear this time around. Using 32bit, I got 180 seconds. This makes it even stranger how for the radial blur filter, I was able to achieve a faster time with 32bit CS4.

I had about 16 minutes, maybe 10.5 runs slower or needs more ram?

Ouch. Was still browsing the internet with a couple of browser windows plus has the usual anitvirus, backup software, etc running in the background if that helps. I didn't see that PS used more than 3.5gb of RAM, certainly didn't go to scratch...
