D²OL faster on Vista?!

[eXceededgoku]

Yo all, I have been using Vista now for just over a week and its fast in everything that I have done with it... including D²OL, I am almost certain I am pumping out a lot more than I was on XP since I can sit and watch the conformers go up 1 by one in about 10-20seconds... I know they may be easy crunches but it just seems like all my candidates are getting wizzed through. Anyone else using Vista and D²OL?

[bullet2urbrain]

interesting, can you give us some more information,

and are you using DSpy? specifically i'd be interested in teh number of atoms and rotatable bonds per Candidate.

Check out DSpy if you arent using it already.

For Instance

# of Atoms : 27 # of bonds: 7
Time per conformer: ~25 seconds on e6600

[eXceededgoku]

Okay I got that Dspy thing

# of atoms : 33 #of bonds 6
Time per conformer: ~13 seconds on my E6600

Haven't tested on XP, but I will do so later

wow my X2 takes at least twice as much :eek:
but nevertheless this is the first time anybody says vista is faster than xp.
I saw some game benchmark and they looked horrible for vista.
Hmmm maybe I can give it a try when I have a new hard disk, my partitions are full :D

[eXceededgoku]

it's only drivers that are the problem atm... So all benchmarks for Vista are basically bulls**t since the driver support is terrible. But overall Vista is faster at nearly everything and I definitely noticed an increase in candidates/conformers being processed.

[SoF]

how is pi :D ? yeah drivers may cause the most loss of performance...let's hope so ;)

[bullet2urbrain]

yes can we see some Pi or perhaps some Sandra/Everest CPU MM performance, if there is a definitive, it may be worth backing up stuff to try Vista RC2

Thanks in Advance :D

[KaptainBlaZzed]

How about some DBench, since we are talking about D2OL.

[eXceededgoku]

SuperPi seems to be about 1-2seconds slower which is strange...
VISTA RC2 beta, 32 bit edition
Memory results
Memory Read - 7854
Memory Write - 7228 :O

Memory Latency - 66ns

CPU arithmetic - Dhrystone - 28697 MIPS - Whetstone - 20248 MFLOPS

XP 32 bit SP2 fully patched

Not really sure if these are good or not :S. On Everest I was completely owning the stock Memory performance with an X6800. So it seems that even though these benchmarks were not made with Vista in mind, Vista is matching the performance of the XP benchmarks :O, and in some cases even beating them. These results don't really show a drastic difference but I assume that is because Everest and SiSoftware were not designed for Vista. My SuperPi score is slower with Vista which could also point to that, as well as chipset drivers most likely.
All in all performance is up in nearly every application regardless of what benchmarks say :)

[IvanAndreevich]

This wouldn't make much sense.

:stick: Pretty eyecandy confuse you?

Except he's right....in most non-synthetics, performance does go up. Vista, when 3D drivers get sorted out, will be the bencher's choice. On top of that, multitasking performance (not usability, PERFORMANCE) is also very much improved in Vista.

The eye candy may not be your thing, but you can turn that off....and the eye candy certainly doesn't hurt performance, it's done all in-GPU, with a CPU overhead equal to XPSP2's. That said, turning off sidebar does help for SPi with Conroe (for the same reason that closing CPUz does...nothing about the OS ;)).

EDIT: BTW, PCMark05 and BOINC are severely faster....I have little doubt that DBench is as well.

[gearhead]

ok cool, i will try it on my P4.
Better than 2000, has to be:)

2003>vista

isn't it? its just vists with a bit less bloat as far as I know, same base, 2k3 is to vista as 2k is to XP

[Vapor]

No, 2k7 is to Vista as 2k3 is to XP as 2k is to itself. Vista, when it comes down to it....really isn't that bloated. Yes, there are somethings to turn off that might accompany a speed increase, but all memory usage is to INCREASE speed (which it does) and its process manager is incredibly more powerful than XP/2k3's when it comes to multitasking or multithreaded apps.

As for DBench, I can't get it to run on Vista with any compatbility mode....closes when I hit enter :confused:

Anyway, my E6700 does ~28-29 sec per conformer on a 38 atom, 9RB task....42sec/conformer on a 35/10........46sec/conformer on a 38/12.......57sec/conformer on a 31/13......10sec/conformer on a 32/5......6sec/conformer on a 19/4......14sec/conformer on a 18/7.....3sec/conformer on a 24/3.....31sec/conformer on a 38/9......22sec/c on a 29/8......8sec/c on a 26/4......24s/c on a 31/8......26s/c on a 32/8......9s/c on a 29/6.....27s/c on a 32/9......23s/c on a 30/8.....7s/c on a 22/5....6s/c on a 21/4......3s/c on a 24/2......7s/c on a 23/5.....9s/c on a 28/5.....21s/c on a 26/7.....8s/c on a 24/6.....24s/c for a 30/8.....11s/c for a 33/6.....85s/c on a 43/14......okay, enough from me :p:

Haven't played with memory at all with C2D....but considering the prefetching enhances mem latency so that it's better than what an A64 can muster, REGARDLESS of mem timings, I have a feeling memspeed is what we're looking for, akin to every other bench on C2D.
