Super-Pi 32M > i965 v. i680 . . .

[hipro5]

Hello all....

Many of you have asked me to do a comparison in Super-Pi 32M between the i965 chipset and the i680 chipset.....
There you go....

I used the EXACT SAME Hard Disk with the EXACT SAME tweaks....I didn't touch the HD so to be equal.....

I used OBP's timings as for the i680 chipset and the rams that where used in both occasions were the Team extreme 1200s....


ASUS P5B-Deluxe i965 chipset with rams at 2:3 and 600MHz (1200MHz DDR).....





ABIT IN9 32X - MAX i680 chipset with rams at 600MHz (1200MHz DDR).....





Now let's talk a bit about these results.....

Firstly if you put on i680 chipset the tRC = 1 , you gain BULL compared to tRC = 8.....
If you put tRRD = 1 instead of 2, you gain BULL out of it....
SO DON'T tell us that the "secret" of the NVIDIA i680 to get lower scores in Super-Pi is the tRC and tWR bulls.....

When I played the Rams at 618MHz on the i680 chipset instead of 600MHz with the above timings, I gained about 3sec in 32M ~13.22m.....

OVERALL: YES the i680 chipset IS FASTER than the i965 chipset as for Super-pi 32M BUT playing our CPU about 100 - 150MHz MORE .....

Any comments will be appreciated.......PLUS ANY of you who has BOTH platforms, try it YOURSELF TOO and find out how "tricky" can be the tRC etc, etc......compared to i965 chipset.....
Bench BOTH 965 and 680 with the same HD (without Intel inf or NVIDIA drivers) and report here too....

FINAL: DON'T tell us bulls about how faster is the i680 compared to i965 chipset coz you know it's .....just....bulls.....and don't try to "blind us" by showing different tables about ram timings and such things coz these are just for "closing people's eyes" and .....Show us FACTS.....I have a FACT here.....
I hope some others will bench with both platforms too, to comfirm this or not....
I'm talking in general here and not for any particular person....

[VictorWang]

lol....bro u can have 2~3sec faster with 965s and 10~15sec faster with 680i.
all the same timings.

[hipro5]

all the same timings.

I know, but I don't show benches here.....I show comparisons between them with the same config...... Plus this is my 3D HD and I tweaked it a bit for the Super-Pi runs.....

PLUS YOU confirm too by your words that i680 IS slower than i965....


EDIT: Another thing is that in Super-Pi 1M you can get (no matter what platform) the EXACT SAME score by working it in SINGE DDR mode than in DUAL DDR mode.....Also you might get even BETTER resaults coz you can tighter MORE one single stick of DDR..... Try it..... ;o)

[KiD0M4N]

Erm, is it just me, or do i notice the 680i running 360x10 on a quad core? If you want a straight on comparision... run it with exact same parameters. Just try putting the X6800 in the 680i board and setting 400x9.

Just my 2 cents,

OK....Would you like 450MHz fsb and 1200MHz rams on i680 to be a bit "better"....?....

Tried that a while back. Dual was only 0.048 faster compared to single in 1M which is less then i would have thought.

[Gautam]

The quad being a B3 will actually be slightly faster in pi than the B2.

Good test hipro, but I agree that it'd be nice to see 400x9 2:3 on the 680i, just to make things clearer to everyone.

I'm doing it now....

[Yoxxy]

I think to make good comparison, exact settings should be used. Use OPB speed and timings to compare.

[hipro5]

Update......

Now.....WHO can save me about 20 more seconds so to beat and overkill the i965 chipset?....






Now we have an EXACT comparison between two of them.....No?......

Save me now 13 + 7 more seconds MINIMUM to outperform the i965......Anyone?.....

[gandalfone]

I will try with dfi dark and dfi 680LT at 400x9 .....but....for me 965 is faster to 680...

Hipro what's volt mem to timing opb?? My team 1200 at 2.7v with dark go to 505Mhz 3.3.3.9....but that timing(opb timing with 680) not working

[hipro5]

I think to make good comparison, exact settings should be used. Use OPB speed and timings to compare.

First I - personaly - don't think OBP's 32M was done at 5420MHz...... and please don't start...... I compare here the i965 v. the i680...... IF you want to "match" somehow OBP's score and convert it at 3600MHz, you have to show me (in general) a score at 3600MHz with the i680 chipset of about 12.55min and below......About his timings, yes they could be done.....

I feed via a DDR Maximizer these Team Xtreme rams at 2.68Volts and I need about 2.71Volts for 618MHz with the above timmings...
tRC = 1 IS a joke.... tRC = 8 is more stable and performs EXACT THE SAME.... It's like the bug - let's say - the ASUS P5B-Deluxe had with booting at Cas 4 and changing it to Cas 3 within Windows BUT the performance was like it was Cas 4..... Just a bug....and for "show off"..... Also tRRD = 1 is the same.....Doing it = 2 is the same....no gain out of it.... Anyone out there could try that....

[zbogorgon]

try virtualization, it shouldn't be much of a problem

[Yoxxy]

To be honest it is never going to be possible to prove any of this stuff.

Everyone is in a crappy position.

You could have booted CAS 5 from Bios, switched to CAS 4 on 680i (which would do nothing) and booted 965p direct. There is just going to be too many variables. The only way you are going to prove beyond a "shadow of a doubt" is by having everyone DV cam any WR run.

it is quite possible to prove !!!

[Enoc]

it is quite possible to prove !!!

yeap..you should prove it...with your wr core 2 duo extreme...5,420mhz should be a peace of cake with your cpu + a i680 board with 1,200mhzrams...
remember to post a vid at those frequencies ...

Many of you have asked me to do a comparison in Super-Pi 32M between the i965 chipset and the i680 chipset....

nice comparo Hipro5 , but there is no need to throw names..is this a comparo o a pursuit?
and the big thing about superpi32m is TWEAKS and BANDWITH...for you to compare 32M pi you have to have the same tweaks...or ask in the XTreme Pi forum after japan legend Newbettle shared some of his tweaks how many seconds a lot of guys have improved...let me say to you this..ALOT...and you forget OS, HD etc..it helps...
so..if you do a 5420mhz run, same os, same hd , same tweaks...then...you should compare...if not...then you can not compare my friend...

you guys should end this...just reunite, bench and learn from each other ...

this is a chase that has no end my friend...

[jmax_oc]

Thank you Hipro for all these explanations.
I didn't use 680i chipset and this is an other reason to confirm my choice.

For this 680i, I thing that the only way to really improve the RAM benefit is not is tighten timings but in sending more datas before raw or lines changes.
However, I don't know if it's possible to do this in nf680i (burst mode at maximum lenght)

[elmor]

Running 400x9 with 680i just doesn't cut it. Try 420x9 on both platforms (clockgen from 400 on both ofc), because bandwidth scales alot with fsb on 680i.

[K404]

tRRD might be a "dud" timing on 965 and 650/680I...i`m not noticing any effect.

Async Latnecy is also a dead timing on 650/680I, at least on Asus- I dont think they bothered setting up a 100% relevant and unique BIOS for the chipset...too busy adding more boards to their product lineup.

[manu]

what ram do you use?

...and it doesnt with the 965 then? Are you saying that at 420 the 680 would somehow magically be faster? That by boosting the FSB by another 5% things would dramatically change?
By "Bandwidth" what kind of bandwidth are we talking about? SAndra?

[SewerSide]

so..if you do a 5420mhz run, same os, same hd , same tweaks...then...you should compare...if not...then you can not compare my friend...

this is exactly what hipro has done, taken 2 mobo's, using the same ram, hd, os install and run the same tests, and has posted his results.

[eva2000]

maybe tRC = 1 versus higher value depends on motherboard ? on my Asus 680i striker extreme tRC 1 was definitely better than 8.

my last 3600mhz 32M on Striker extreme was

with Team 6400C3



with OCZ PC2-8000 Titanium Alpha VX2



playing with P5K Deluxe now

At certain ram dividers 680i MAY beat 965P since it has unlinked mode though. But anyone knows 965P tweaked at same clock speeds will beat 680i chipset.

[Enoc]

I need to learn how to read!

he cannot compare his results with OPBs cause he needs to run same cpu frequency 5420mhz, same os, same hd , same tweaks as OPB , THEN he can compare...it's all i'm saying...this is not superpi1m...

[dinos22]

hipro you are wasting your time bother ...............can't beat P965 with 680i

LOL elmor what kinda comment is that ... you even woke up macci to give you a slapper ROFL
