Very quick 3 x HD5870 benchmark

Ok, so a few days ago I was testing for an article regarding 5870 multi-card performance scaling. And while I was at it, I noticed the obvious, these puppies need a stronger CPU even when ther run at stock speeds. So I pushed my litle i975 up a little bit, and there you go, some lame, air-cooled, stock clocks VGA results :D

Don't get scared by the old GPU-Z wrong readings of the specs, 0.3.5 didn't work for me with 3 cards under WIN 7 :(

Intel Core i7 975 @ 4900MHz (lame)
Asus P6T7 Supercomputer
3 x 2GB Kingston DDR3 2000 CL8
Asus HD5870 / Gigabyte HD5870 / HIS HD5870 - 850/1200MHz
OCZ EliteXtreme 1000W

Good bench.:up:

Very nice :D

need to push that cpu a bit more ;)

finally some CFX! 03 looks very good on these cards so far - hoping that the low-bug is not that hard on 5870 anymore! looks very promising what you have shown us, now start kicking VGA and damn get that CPU past 5.2 :D :D :D

Yes sir!

I will test a new CPU once I fill my dewars, this is not quite a champ :p

Not much of a gain from 3 HD4890's though.

Not much but you are running 150Mhz more on core :p:
Good to go Monstru:D

Nice start Monstru :up:

wait to see next round from you mate ;)

thanks for sharing finaly CFX
any problem with the cards in general ?

Very nice... scaling looks great... I love this 2003.
Please can you test the CPU scaling? I bet the score will raise huge with higher CPU clocks... we will see :)

THX for sharing...

Nice scores monstru...the cards look great...if you raise the cpu clock i think you'll see a great boost...we're waiting for ln2 results

Monstru

hiwa - no major problems bro, but on the P6T7 they are pretty close to each other, so they get really hot even at stock clocks. This should not be an issue under cold though. Also, the software suport is flimsy yet, they can be overclocked one at the time with AMD GPU Clock Tool or CCC, or even Riva Tuner with edited config, but...it does not feel right yet. I suppose pretty soon this will be solved.

loopy83 - I will test with a different CPU once I fill my LN2 tanks again, and maybe I will get higher clocks on the CPU. Untill now, just to see the scaling with the cpu, I had the following results with the same CPU at 4GHz and WIN 7 32 (results are worse on Vista x64):

2003 - 143677
2005 - 35741
2006 - 28304

sofos1990, crustytheclown, ZoLKoRn - thx guys :D LN2 results will come a little bit later, once I finish with some stuff. Untill then, I will show you guys how 4 cards work, but unfortunately I do not have LN2 for the CPU anymore at the moment, so the scaling will be poor.

;):up: that's cool i'll try 2 of them next week
i kept 2 of my 4890's caz wasn't sure about their power,this is the first CFX result in XS so i tought maybe they have some truble or something was wrong wirh them :D , thanks for your confirm, i'll sell my 4890's and get third video ;)

Well, if I knew I should have posted 2 days ago when I got the results, but I thought they were a little bit to lame, all stock cards and such :)

One funny thing though. It is the FIRST time in my life ever when I put on the system more the one ATI card, and after the drivers are installed and I restart the system, the crossfire is enabled without any problems. Usually I would have to struggle a make it work, now it just works from the first re-boot.

CAN NOT THE KINGDOM OF SALVATION TAKE ME HOME Cliff Burton Solos

Sorry for the off topic, just saw the link in your sig there and thanks for that, Burton was a _god_ on the bass.... Never thought to check out utube for that...

/back on topic...

ahm yea, nice runs ^_^

Cliff Burton was indeed one of the holy names of metal. The good die young :(

Back to our ATI's, what could this be? :)

Give me one hehehe :D

its very tight between the cards.. how is cooling affected on the upper card, from being so close to the lower card?
10-01-2009, 04:12 AM
Monstru

All the cards are affected by this, except the last one. They get pretty hot, so the fan has to be kicked up to 60-70% to keep everything ok, even at stock clocks.

ZoLKoRn - I would bro, but I had to fight an army of AMD ninjas to get these, so I must use them fast, untill they find me:D

Peace...

Wow Nice Qcfx there man
when you can please do some 3d @ 4500 i wanna compare them with 4890 Qcfx :up:
10-01-2009, 04:17 AM
Monstru

Ok, I will try when I get some SS or something cold on this CPU. The ideea is that driver support is probably pretty poor atm, allready I see lower numbers then I saw with 3 cards :(

I don't think we will see so much increase in 3dmark results with 5 ghz core i7...

These vga's are very powerful, there is too much cpu bottleneck.

Monstru can u run a 3dmark vantage gpu test xtreme to show the real gain of 5870 crossfire?

Thanks for the post.
Man those cards are a tight fit.

Looking super powerful!

wow very nice... bit disappointed it's so cpu limited as i was hopin 33k 3dmark06 would be possible with 3x hd5870 with i7 cpu around 4500-4600mhz ht enabled ?
10-01-2009, 07:28 AM
CAUTION

Great setup Monstru and I can't wait for your next run at 3D06. :clap:

.p4nzer - with 3 and 4 cards I have a weird GT1 bug (like I had here). Anyway, I am working like crazy, I hope to publish tomorrow or in 2 days, there are tons of interesting findings and I have to analyse a lot. Weird stuff happen when you put 3 and 4 cards in a set-up. You see all sorts of behaviour, like FarCry2 perfectly scaling while Crysis is just dull, and the freakiest thing - 3 x 5870 on P55 havinf the same performance as 3 x 5870 on X58...Now this is something to sleep on. :)

WOW

nice man
10-01-2009, 01:41 PM
Monstru

Thx man!

That "p55 has the same performance" works only in 3DMark....Mr FarCry 2 does not agree. I will investigate more :D

Uuuuuf, finnaly managed to publish the article.

Here you go gents, HD5870 vs 2 x HD5870 vs 3 x HD 5870 (P55) vs HD5870 vs 2 x HD 5870 vs 3 x H 5870 vs 4 x HD 5870 (X58).

farcry 2 2x/4x aa 2560x1600 numbers look odd?

Thank you for the heads up, it is the other way around (when I did the graphs I used the 2x data for 4x and 4x data for 2x). The graph is updated now.
