Mike has already posteded benchmarks for 2 different versions of prime95. However, he isn't really getting a speed boost because (i am assuming) that his P4 is 32bit, and 24.11 only gave a speed boost to 64 bit chips.

Can someone please correct me if I am wrong?

I am a little confused. I don't see a significant speed boost... is there another reason why you like it over 23.8 or am I just reading the numbers wrong?

The difference isn't significant, but version 24 is a TAD faster.

Best time for 512K FFT length: 18.868 ms. vs. 18.406 ms. (0.462 ms better.)
Best time for 1024K FFT length: 36.528 ms. vs. 36.297 ms. (0.231 ms better.)
Best time for 2048K FFT length: 79.702 ms. vs. 78.504 ms. (1.198 ms better.)

I'll take whatever advantage, however slight it is.

Starting with 512K FFT length and finishing with 2048K FFT length he has shown the following improvements:

2.51%
2.00%
0.83%
0.69%
0.64%
0.98%
0.21%
1.04%
1.53%

1. The last FIVE posts would have been better placed under the so-called "perpetual benchmark thread".

2. You will see for example, I ran the new 24.11 client on a 630 machine and posted there not here.

3. If you are running/benchmarking this beta client please say EXACTLY what version of 24.11 you have (ie by date downloaded from the ftp server or subversion number) since it has been through at least FOUR updates already.

4. Yes, the improvement on P4 is only slight but it is a little faster which I welcome.

5. I like 24.11 because of the ability to benchmark trial factoring.

6. I also like it because of the massive performance jump if you are running in 64 bit mode (eg Athlon64 with 64 bit windows beta).

7. I hope that not too long in the future, we can get this for 64-bit Linux eg on Athlon64 or Intel 6xx / 8xx with EM64T.

8. My own opinion is that this thread is best left for feedback of experiences with the beta like bug reports, testing queries etc.

Default EM64T results

I asked on the Aceshardware forum, if someone could test Prime95 21.11 on an EM64T CPU with 64 bit OS. And got results

Default Please display 32 or 64 bit for benchmarking

Just an idea, but now that a 64 bit version exists, from the number of benchmarks getting posted it is not always immediately obvious whether the machine is running in 32 or 64 bit mode.

When the benchmark prints out version number, processor speed etc could it possibly also display 32bit or 64bit which should be readily available to the client as they are distinct executables.

This will standardise where to find this info in a benchmark and save people having to say or ask which it is.

Default Dual Booting with both new 24.11's

Hello,

I'm dual booting now with Windows XP Pro and XP Pro x64 Edition and would like to use the same data files to work on the same numbers between boots. Is this supported with this new version of Prime95 24.11? And if so what would be the best practice.

I have a common drive M that stays the same on both boots, but the C & D drive swap depending what OS I'm in. This shouldn't be a problem though I wouldn't think as long as I can direct the Prime95 clients to work from the data located on the M drive (if I can do that).

Any help would be greatly appreciated. Thanks!

Install Prime95 to your M and it all should be fine. After swaping to the other operating system, manually start Prime again and it should then start again no problem.

Thanks for the quick reply, but the problem is that I want to use the 32bit version of Prime95 on the 32bit OS and the 64bit version under the 64bit OS...

Problem being that they have the same exe name and you can't have them both under the same directory. It's one or the other, not both.
