PAR2-benchmarks for Conroe CPUs?

[vsonerud]

Hi!

Does anyone know of any published benchmarks for PAR2-generation/repair using Conroe CPUs?

Or maybe someone reading this forum who has a Conroe CPU could do a small test?

I am just very curious as to approx. how many MB/sec one is able to achieve for PAR2 generation using various Conroe CPUs, especially in comparison with AMD X2 CPUs

( I am currently considering a system upgrade - and PAR2 benchmarks are important for me as part of that decision-making )

I was just doing a few repairs last night and I was regularly getting 1100MB/s with my E6400@3ghz

OK, I had hoped it should be even faster.

I have seen other reports saying approx. this:

AMD X2 3800+ (stock speed): 750-800 MB/sec
AMD X2 3800+ (2.5 Ghz): 925 MB/sec
AMD X2 4800+ (stock speed): 930 MB/sec

My system - AMD Athlon XP 2200+: 375 MB/sec

I do roughly 1300MB/s.

I've seen higher-clocked ones do 1500MB/s.

For reference, my old X2 was in the 800-850 neighborhood.

On stock? Strange. My memory timings are currently extremely loose, so maybe that's why mine is slower.

 

[Pabster]

No, both of those results are from overclocked machines

Is PAR2 memory bottlenecked? It's only reported around 600MB/s on my E6400. I'm still using 512MB of DDR400 on my ASRock VSTA mobo. For comparison sake, my other 512MB stick is running in my old 3.4 Northwood. That system is reported at 400MB/s

Yes, RAM timing and bandwidth make a big difference. As does disk speed.

You should be doing better than 600MB/s on an E6400, even stock. I suspect the ASRock is holding you back.

What's PAR2?

Just added the 512 stick from the other system and it jumped to 700MB/s. So yeah, definitely memory bandwidth limited.

It's a file verification and recovery system.
