3xCF HD4670 amazing scale with i7 920 LN2 action!

Hello, today i have some event with Gigabyte on Commart2008 event at Gigabyte partner booth and on event we are presentation of ln2 overclocking with i7 920+EX58-UD3P and cheaper card from ati by HD4670CFX :D well after first benched :eek: wow it make me shocked !!!.... so let to see what is make me shocked :D

some pics on event...

Huh... that really good scale from 2xCF and 3xCF for some cheaper gfx from ATI ;)

Thank you GIGABYTE

Heck, those are some great scores form budget cards, never mind the scaling.

Thanks for posting!

Cute cards :p: Can't overclock any higher or just CCC limited?

wow that's amazing! :D
3xCF 4670 FTW! :up:

no 4 card setup ?
come on with scaling like that, it'll be great to see.
vista 32bit or 64 bit ?
I seen hex got really go scaling with 4830's in crossfire.

Wow, scaling is indeed impressive. thanks for sharing Zolkorn!

Yep limited of CCC at 778MHz GPU and 1100MHz Memory :)

UD5P only have 3x picex16 for gfx and it run on Vista 32bit
Thank you :)

yah it very impressive for price and performance too ;)

Nice results ZoLKoRn.:)

I have two of these already and the third one is coming tomorrow, so I'll have some results by the end of the weekend to share.;)

Sounds like it's time to do a bios and vmod ;) I bet 900MHz on air is easily possible.

thx for posting zolkorn

seems quite sweet

now its time to get them under cold with preperation mentioned @ gomeler

Nice, I think you and Shamino are the only guys ever to run tri-fire ;) :D

For those who want an overview:

Performance efficiency of adding a third card, based on these three benchmarks: 63% :eek:

thx for building a overview once again Pieter and ya its quite impressive, thats the scaling we wanna see uh :D

2003 efficiency is great.. I love to see this kind of chepar stuff :D

Thanks Zolkorn:up:

Thanks for make the graph massman :up: well tomorrow i'll testing on single and come to update again for more compared of scaling ;)

little update some pics from event today :D come to see who help me pouring ln2 ! :p:

wow she is beautiful lol :)

so i'm curious, it seems that this card in 3-way Xfire scores almost the same in 06 as three way SLI of the 260? IS this true?? I mean wow, such a difference in price, why would anyone get three 260's when they can get 3 4670's for probably the price of one 260???

Uhh.. Tri-Sli GTX260s would score much more than 24k in 06. Probably looking at ~27.5k with tri-sli and his 965 at those speeds.

i got 26890 with dual 260s and i940 @ 4.2

amazing scaling

could be be something wrong with these drivers maybe cause that's just excellent

i guess we'll see the full picture when you compare single dual and tripple on a graph :up::up:

3damrk06 gained 6,400 points going from 2 to three card it it where that good gin when the 4th was added he'd hit just above 30,000.

It's a little strangetht the 3dmark05 came lower when the third card was added 4,000points

If you want to see real scaling, bench F.E.A.R and you will see almost 100% scaling from single card > SLI > Tri SLI and the same for crossfire.

Why not, this is 3870x2 in single gpu format...depending on clocks, it could be close. If this gpu had 4870's PWM...

update more result from single-card and all new tried 2xCF and 3xCF

:p:

Interesting to see that cpu score in Vantage goes up with multi gpu, and third card 3D score doubles dual card.

Somewhere between 1280 and 1400 shaders becomes optimal for this bench. Quite interesting, that one, so close to # of pxeils in resolution of the bench...;)...seems ati made a good choice for frequency...

That Vantage scaling is simply unbelievable :eek:

Performance scaling over single card:

Crossfire link-up efficiency:

http://i154.photobucket.com/albums/s.../4670-2_wm.png

Understand this graph as follows: if a single card performs at 100%, how does two cards each perform in comparison to a single card. 100% means that the two cards each perform as good as one card, resulting in a score that is twice as high. If a dual card solution has a rating of 50%; it means that Single or CF has no effect on the score; in tri-cf config 33% means no effect.

:shocked: linear increase
that IS AMAZING

massman,
Is there any 3DMark scores for the single Radeon HD4670 on that config? I would like to compare with my Palit Radeon HD4670 Super 512MB graphics card.

I only did the charts, Zolkorn did all the testing. You can find the bare results on page 1.

Well isnt some of this down to the GPU being the absolute bottleneck- especially in single card?

After that, id put some of the scaling down to the 3DM score formulae and coding

The score improvements would be less by moving from 3-4 cards as the balance of power moves closer to equilibrium...maybe even tip the bottleneck back to the CPU?

Having said that, results like these make me quite happy about how ATI have implemented their multi-GPU solution. Good engineering well implemented.....finally!

Here is 3DMark06 score for my Palit Radeon HD4670 Super 512MB graphics card:

SM2.0 Score: 3182
HDR/SM3.0 Score: 3694

http://pic.ipicture.ru/uploads/08112...p4OlUJR4CJ.gif

A little lower comparing to Zolkorn's results due to Windows XP/Server2003 display drivers. I think drivers for Vista have some specific optimisations that increase an overall performnce.

Added:

I have just installed 80mm fan on the bottom side of the graphics card to cool VRAM chips. I have also rise the VRAM frequency up to 1100MHz and GPU clock up to 826MHz. Well, I am actually not impressed with my new 3Dmark06 score:

SM2.0 Score: 3172
HDR/SM3.0 Score: 3854

wow! 3xCF is amazing!

Yes I've seen 8600s do 100% scaling in SLi. GPUs need to get off the PCI-E bus and onto the QPI bus IMHO

woah... gotta think twice about tri - cf now :P

Wow, this is amazing!

I think I have some idea where ATI can go with their next cards now. :D
