It seems some AMD owners are spicing the benchmarks with fake results, for instance :

Phenom 9600 Quad-Core with 0.99 and 1.15 factoring times (the other results are more in 9 second ranges.)

Code:

AMD Athlon 64 3200+ 2210  7.13  7.96  9.90 12.07 14.89 16.80  24.55  30.21  35.81  39.69  2.05
while the other lines are more like
AMD Athlon 64 3200+ 2583 34.53 38.38 48.54 59.48 72.12 80.09 107.96 132.09 163.28 178.01 10.63

The whole benchmark page would need a lot of consolidating work (removing duplicate entries amongst other things...)

Can anyone with a PhenomII please post a benchmark, please?

Phenom 940Blk 3.0GHz (Stock clock, voltages, timings, etc.) on GA-MA78GPM-UD2H with 1066 DDR2 @ 5-5-5-15. Using sideport graphics memory only, Vista Ultimate 64 bit with Aero enabled.

sdbardwick · 2009-04-28, 01:48

I need to do some more investigation regarding the above Phenom II. I have no idea why multithreading scales so badly at lower FFT sizes. It is currently running 1 doublecheck per core quite nicely (27ms/it 1280k FFT on each core).

Medion Akoya MD 97110 (aka P6612) notebook. Didn't fiddle with any BIOS settings yet. Benchmark uses FullBench=1 and AllBench=1.

If you would like your benchmark included on my benchmark or throughput pages, please re-run the benchmark without AllBench set (FullBench is welcome, but my code isn't set up to parse the complex AllBench output)

This time, without AllBench=1...

Maybe some faster Hardware are out there!

I have a small question, is it suppose to look like this or is this usually not happening.

4x1024 Corsair DDR2 @ 4-4-4-12 800 MHz. 2.14 volts

Looks pretty normal to me. Why do you ask?

Where can one find the benchmark applications?

You use Prime95.
(optionally) First, close Prime95, and add FullBench=1 on a new line at the top of prime.txt (in the Prime95 folder). This will make it run on very small (down to 4K, normally 768K) and very large (up to 32M, normally 8M) FFT sizes instead of just the ones you might run into in GIMPS. (end optional)
Choose Options > Benchmark in Prime95, and wait for it to finish (takes several minutes). You have to use Test > Stop to stop any work before running the Benchmark. Needless to say, you should try to keep tasks, even mouse moving, to a minimum during it so that it gives consistent results.
I'm pretty sure that it will communicate the results to the v5 server once it completes (in the next comm., of course, which you can do immediately with Advanced > Manual Communication), if that Prime95 instance is set to use PrimeNet for assignments and such. If not and you want them included, you could probably email the results.txt to

(prior to PrimeNet v5 this was the only way)

Well cause running 4 threads = almost useless. Cause 2 threads will always be faster. Weird.

How come it slower with 3 and 4 threads :(

When only doing 2 threads:
Well I'm currently doing 2 Double-checks of a M21xxxxxxx and they both have around 0.034 sec per iteration (FFT sizes 1280K)

and as soon as I run the 2 Lucas-Lehmer of a M43xxxxxxx with FFT sizes 2560K on the other 2 cores

It becomes:
2 Double-checks of a M21xxxxxxx and they both have around 0.074 sec per iteration (FFT sizes 1280K)
2 Lucas-Lehmer of a M43xxxxxxx will both have around 0.143 sec per iteration (FFT sizes 2560K)

If I only do the 2 LL on 3rd+4th worker they both run around 0.069 sec per iteration (FFT sizes 2560)

How come my 1st+2nd thread become slower as soon as the 3rd+4th thread gets activated.

My CPU should not have any problems with 4 threads.

It can't be the memory bandwith cause thats more than what the Bus speed of my CPU is.

Memory runs a 400 Bus speed (800 MHz. DDR2) with 4-4-4-12. which should be more than enough to feed the CPU with data cause it runs on a 333 Bus speed.

Or should I use the Quad-bumbed bus speed and the DDR2 speed for comparing. (Cause then yes I'm 533 Mhz. short as 800+533=1333 )

It's because of limitation on simultaneous memory accesses by the cores. Prime95 accesses memory faster than almost any other application -- its top speed is usually determined by how fast the memory controller can provide it with all the fetches it requests.

Multicore systems are usually not designed to allow maximum memory access speed to all cores simultaneously, because it's so rare for any application to be able to use that simultaneous maximum effectively.

To achieve maximum performance with your Core2Quad, you should overclock bus speed to 400MHz (1600 effective) and more importantly upgrade memory to at least DDR2-1066. Even then you will encounter memory/bus saturation for tests involving FFT lengths greater than 256k.

Thought I'd post what I'm doing, thought it may interest.

On a core i7, I'm running 1x (P-1), 2x DC, 1x "whatever makes sense" (LL) on mprime (OS=centos 5.4). I'm running only 1x P-1 now, as with running multiple P-1, mprime tends to crash when it allocates memory for p-1 workers (and also crashes other processes on the system).

When running these workers, the per iteration times were:
1280K FFT 0.026 - 0.028sec (double checks)
2560K FFT 0.055 - 0.058sec (1st time LL)

vs single-thread benchmarks of
Best time for 1280K FFT length: 22.735 ms.
Best time for 2560K FFT length: 50.253 ms.

calculated max deviation from benchmark:
1280K FFT +23% (double checks)
2560K FFT +15% (1st time LL)

Code:

How much memory have you given mprime? It shouldn't crash. Try telling it to only use 1/5 of your real memory.

S485122 "Jacob" Sep 2006 Brussels, Belgium 2·3²·5·19 Posts	Fake Benchmarks It seems some AMD owners are spicing the benchmarks with fake results, for instance : Phenom 9600 Quad-Core with 0.99 and 1.15 factoring times (the other results are more in 9 second ranges.) Code: AMD Athlon 64 3200+ 2210 7.13 7.96 9.90 12.07 14.89 16.80 24.55 30.21 35.81 39.69 2.05 while the other lines are more like AMD Athlon 64 3200+ 2583 34.53 38.38 48.54 59.48 72.12 80.09 107.96 132.09 163.28 178.01 10.63 The whole benchmark page would need a lot of consolidating work (removing duplicate entries amongst other things...)

Shinzok Oct 2008 Zevenbergen, NL 6₈ Posts	Well cause running 4 threads = almost useless. Cause 2 threads will always be faster. Weird. How come it slower with 3 and 4 threads :( When only doing 2 threads: Well I'm currently doing 2 Double-checks of a M21xxxxxxx and they both have around 0.034 sec per iteration (FFT sizes 1280K) and as soon as I run the 2 Lucas-Lehmer of a M43xxxxxxx with FFT sizes 2560K on the other 2 cores It becomes: 2 Double-checks of a M21xxxxxxx and they both have around 0.074 sec per iteration (FFT sizes 1280K) 2 Lucas-Lehmer of a M43xxxxxxx will both have around 0.143 sec per iteration (FFT sizes 2560K) If I only do the 2 LL on 3rd+4th worker they both run around 0.069 sec per iteration (FFT sizes 2560) How come my 1st+2nd thread become slower as soon as the 3rd+4th thread gets activated. My CPU should not have any problems with 4 threads. It can't be the memory bandwith cause thats more than what the Bus speed of my CPU is. Memory runs a 400 Bus speed (800 MHz. DDR2) with 4-4-4-12. which should be more than enough to feed the CPU with data cause it runs on a 333 Bus speed. Or should I use the Quad-bumbed bus speed and the DDR2 speed for comparing. (Cause then yes I'm 533 Mhz. short as 800+533=1333 ) Last fiddled with by Shinzok on 2009-08-17 at 20:21

sdbardwick Aug 2002 North San Diego County 5×137 Posts	I need to do some more investigation regarding the above Phenom II. I have no idea why multithreading scales so badly at lower FFT sizes. It is currently running 1 doublecheck per core quite nicely (27ms/it 1280k FFT on each core).
