In this review, it seems almost every case of AA/AF turned on the 4850 came out ahead, it was only when they were off, that the 9800gtx nudged ahead..Quote:

Because in 2007 nobody had Crossfire because of prices and because the perfomance was not there. Now every average joe can build a 3850CF system with the money of a single 9800GTX. Again, my question: have you ever tried CF or you're basing your opinion in reviews? I smell a no, so I'll tell you not to speak about something you don't know.Quote:

Another review with a bit of overclocking.
http://www.legitreviews.com/article/731/1/
Seems like a driver issue to me as the 3870X2 is way up there... ...although it has "internal" crossfire... :p:Quote:

They'd better fix that, i fully plan on playing through The Witcher again when my new build is complete :yepp:
Let me get this straight.
The 4850 is as fast or sometimes a bit slower than the 9800GTX without AA, but once you turn on AA the 4850 is noticeably faster. It's beaten by the 9800GTX+ without AA, but with AA it seems to still be faster.
It's like a 9600GT kinda, but with a really good price and better overall performance.
This is just my opinion, BTW.
Hi guys.
Just wanted to let you know that we've done much more extensive testing and published an updated review.
The address is this: http://hwzone.co.il/reviews/4850_preview/
It is also the second review mentioned in the beginning of the thread ("HardwareZone").
We've done some extensive testings which include CF in 8x/8x mode(P35 board) and CF in 16x/16x PCIE 2.0 mode (X48). The results are quite remarkable!
Nice update GGuyz...
I remember only the Ultra pegging the limit of 8x anyway, and since this card 4850 sometimes matches/beats the Ultra, Im not surprised there is an increase in some items when going 16x/16x.
Though Im a little confused about how that all works personally. Crossfire still uses one pcie slot in either 8 or 16 lanes flavors for each card. Since they each use their own, why would crossfire matter? Shouldnt you see the same improvements with one card since they dont share that bandwidth?
What are the differences at 16x/8x?
Wait a minute, does this mean I need to have two 16x pci-e lanes for a HD4850 crossfire setup to perform to its fullest??? :confused:
You are right. we saw similar differences when testing a single card in 8x/16x mode. But there's no real reason to run a single card in 8x mode.Quote:

I think the new P45 boards would be sufficient. Most of them only support 8x/8x mode but allow PCI-E 2.0 bandwidth. It's more or less the same as 16x/16x. Atleast in theory.Quote:

The p45 was testing against the X48 with two 4850s in crossfire.Quote:

Perkam
So I'm SOL with my P35 board? I haven't even had a chance to use it yet for more than 48 hours and now it needs to be replaced? @#$@#$%. Well there's only so much I can complain about the new graphics cards being too fast for my motherboard.
wow!! 56% improvement on fps in crysis is quite remarkable.Quote:

Thats a big dent into price vs performance.
Ok sli motherboard can be had for 65 euro, 2 8800gt can be had for 220 euro or 2 9800gtx+ for 350 euro when released
x48 will cost 160 euro mimimum, 2 HD4850 300 euro ( €185 more than 8800gt sli combo ), sli seems to have better consistency and support, while 8800gt sli is very near HD4850 crossfire performance
Not a fan boy, just pointing out
So the P45 is really no good for Crossfire with 4850's then, is that what you're saying?
No. I bought it in March. I've been working on my water cooling system for that long :). Also it's a uATX board. I'm not sure how easy it is going to be to find a x48 replacement that overclocks well , but I'm going to start looking today.Quote:

Whats wrong with 780i? See sig for details!
The results are impressive but I wouldn't rush to buy a new board. Crysis has the biggest improvement because it's bandwidth hungry. The rest of the games have moderate differences which may make you reconsider your next board, but I wouldn't replace the current board just for that reason.
That's my opinion anyway :)
Wait for the free update to the enhanced edition in September. Gameplay improvements, much improved graphics and character expressiveness, completely redone voice acting with longer scrip, etc.Quote:

Crosslinx helped by using 8x/8x which turn out to be better (back then). I think Tech Report did a review about it if memory serves me correctly (may have been another review site).
oh my god what a difference :eek::eek::eek::eek: nice findQuote:

Same as x35 (mainstream) vs. x38 (performance).
Between x38 and x48 there is no noticeable difference in performance, only some features.
So, buy yourself a Maximus Formula, for instance, and be on top.
Bugger - no P45 Deluxe with 16-phase power for....just the crappy old P5E *cries*
Put ICH10R on the x38 dammit! :(
I'm getting a little confused here. Is there any (theoretical) problem running a 4870x2 with a P35 chipset if you don't plan to do CrossfireX? Is this an issue only if you are doing multi-slot CF?
Nope.Quote:

P45 chipset runs equivalent to 16x/16x (ver 1.0) in xfire mode = faster than P35 @ 8x/8x or 16x/4xQuote:

Thats whats confusing me....surely 8x/8x PCIe 2.0 is enough for CF, its the same as having two 16x PCIe 1.0 slots in terms of bandwidth....are we really needing all 16 lanes of PCIe 2.0 bandwidth per card for CF these days? If so, whats the point of connecting the cards together?
To jas and Kai, you're absolutely right in that you shouldn't be forced to upgrade. However, there is a solution. The SPs on the 4850 should be very bandwith-starved relative to the 4870. If my theory is correct, the performance delta between 2x8 and 2x16 should be smaller with the 4870 than the 4850.
Technically, one could argue that from the money you save from buying two 4850s and ocing them, you can buy the new mobo. Additionally, for those that say that buying the new mobo takes away from the price/performance, that is not true. Because you are paying for more performance for the GPUs and CPUs, it balances out.
The inconvenience stays, however, and users have every right to be mad at AMD/ATI for not addressing this.
Perkam
the P45 and the X38 are the same in price, i'm just annoyed that i find out NOW after having planned for so long to get a P45....i wanted the ICH10R capabilities with the crossfire capability, but crossfire takes precedence, so once i buy another 500gb drive, all my SATA ports on the ICH9R will be tapped out....and you cant get non-raid addin cards!
Still, if someone could benchmark the CF difference between the P45 and the X38 (in english), it would assist me (and likely others) even further.
Check the 4Ghz 4850 Tweaktown preview, they have the comparison there.Quote:

The performance of the X38 isnt in question - its the fact the X38 only has the ICH9R....which has been around so long, i have it on my ancient P5B-E!
Aaah this one, you mean:

You could just keep your current mobo and get a HD4870 X2Quote:

There would be absolutely no point in making if it couldnt do it.
I personally think that tech is much too complex, but if true it should perform better than a 4870 CF... by how much... probably 15 - 25 %
None of that micro stuttering bollix to deal with either

Now, having looked at that review at Tweaktown, i thought...'hmm, i can take a 10% performance hit' and seeing as i have a 1440x900 monitor, the hit was negligible, but once it got to Crysis....ouch - talk about a hit :/
Looks like the X38 is it for me i think....

Getting an x2 for example, will work as well using a p45 chipset.
Since the asus p5q deluxe scale well in fsb and will be good until any upgrade for the nalle from Intel I recon it will do just fine.
As Perkam noted, 4850 might be limited and next week the 4870 might be similiar in performance with p45/x48. They will however scale badly in crysis since the gamemakers with that engine didnt do Crossfire justice.
Great job guys, make a game engine (Crysis) that dont take advantage of the new tech when no machine can run it well, who makes such decisons really?:down:
I bought the P45, I rather get a new tech with fixed old problems than buy the old ones, I might get new problems but that is the gamble ;)
The machine I got is fast enough, but I just enjoy upgrading since it is a hand on job and I just love the smell of new components.
as an advice, I would wait before I make conclusions regarding p45/x48 and crossfire scaling, Internet is to fast that decisions needs to be waited until all info is on the plate.
Bring it on ATI we are all ears.
Excep the minbari ofc.
From the Anandtech 4850 review:
http://www.anandtech.com/video/showdoc.aspx?i=3338&p=13
Below is the performance difference between the GTX260 and HD4850 @1920x1200 resolution:
Crysis 1920x1200 :
GTX260 : 28.6 +19.1%
HD 4850: 24
Call of Duty 1920x1200:
GTX260 : 74.3 +11.8%
HD 4850: 66.5
Quake Wars 1920x1200:
GTX260 : 84.2 +11.6%
HD 4850: 75.4
Assassins Creed 1920x1200:
GTX260 : 50.2 +7.7%
HD 4850: 46.6
Oblivion 1920x1200:
GTX260 : 43 +23.5%
HD 4850: 34.8
The Witcher 1920x1200:
GTX260 : 46.1 +33.6%
HD 4850: 34.5
Bioshock 1920x1200:
GTX260 : 50.4 -10.3%
HD 4850: 55.6
-------------------
Average gain over 4850: +13.8%
HD4850 performance is not bad for a card that costs half the price ($200 vs. $400).
And if we take into account the fact that HD 4870 will be at least 20% faster than the 4850, we can assume it will beat the GTX260 in most cases. It's good for us because this will only mean a price war, and both the GTX260 and HD 4870 should be great cards :yepp:
Looks to me like Crossfire scales fine - see here:
http://images.anandtech.com/graphs/a...5229/17096.png
I'll need to make up my mind as to P45 vs X38 soon - i hope there are more reviews of what this can do in CF and if the tweaktown review was indeed correct in stating that bandwidth heavy games, like Crysis, need more than simple 8x PCIe 2.0 slots. I dont care about the gap over 1920x1200, cause as i said, i have a 1440x900 monitor...
Please clarify your quote, you start off talking about the GTX260 and then the figures you quote are for the 9800GTX....what exactly are you trying to say, that the HD4850 is slower than the 9800GTX, the GTX260, the 9800GX2, the GTX280 - what? BE CLEARER.Quote:

That crysis would be so heavy on the lanes I dont buy into, I bet the game since it uses a different engine than most games out there also has something to do with it.
so 1 game, crysis, isnt up for very high, all the other games works fine using p45, for me the decision is clear, crossfire works just fine on the p45.
I would still wait for the x2, if the rumours are true, ati has a good and real edge there.:clap:
Sorry, those were the GTX260 numbers. Fixed now.Quote:

It will be held back if you don't have X38/X48. You need two PCI-e 2.0 16X lanes to get the full benefit of Crossfire with these cards. The loss in Crossfire with two PCI-e 8X lanes is substantial, at least in my opinion.Quote:

EDIT: OMG some people are stoopid!
for 1 4850 don't think it will matter, maybe not with the 4870, but with 4870x2 yes maybe it would be held backQuote:

Well, the question for me is how much will two 8x pci-e lanes hold a 4850 crossfire setup back in that resolution. It might still be worth getting a second one if the difference isn't that great in games other than Crysis.
this had bin posted b4 but show p45 8x 8x to x48 16x 16x

Guess worrying about anything NDA related is moot.
Just picked up 2 4850's for $300 usd :up:, at best buy of all places haha
they're 149 there? huh?
Since HD4850's are avaliable in stores we were allowed to release performance numbers and talk about retail packages, but we're still bound by the NDA not to release architecture details or clock speeds (despite that information being readily avaliable to the public).Quote:

After speaking to AMD we were told we could release certain pieces of information and not others. Wanting to maintain our good relationship with the company we are abiding by their wishes no matter how we might disagree. Come tuesday we will be unbound from the NDA and the floodgates will open properly :D
We will be using the 680i for SLI and x48 for crossfire numbers.Quote:

hey isn't it possible to get xfire to work on an nvidia chipset with the right drivers? If that's possible then I wouldn't have to upgrade my old 590 sli setup (amd rig, lol 590 sli + conroe = epic fail)
I recently picked two (Visiontek) of these up for some crossfire goodness. You can see my system specs below. I'm not a fan boy and both Nvidia and Ati can kiss my arse. I'll share a few observations. These cards run hot as hell. You will burn your fingers trying to touch these after running for a few minutes. Idles around 78* and loads well over 90*. I have 4 120MM fans blowing on the case side and I encountered numerous lockups at stock speeds. Default fan speeds suck and hopefully rivatuner will allow for adjustments. Crossfire doesn't scale all that well on my current motherboard. I had various lockups and performance wasn't that impressive. Other reviews seemed much better. I loaded updated 8.6 drivers and the Vista X64 hotfix, but nothing really mattered. Ati should drop the price on this thing closer to $130 for this to be a decent deal and use a better cooler. I'm sure others might have better luck with a dual x16 Pci Express board, but I still expected more out of this with my P35 chipset. I think I'm going to stepup to a GTX 260 and trade-in my G92 GTS. However, I would definitely recommend the G92 GTS over the Ati 4850 at current price levels and I would be cautious with crossfire on certain mainboards because YMMV.
Final conclusions: (1) seems slower than a G92 GTS for around the same price and (2) G92 GTS runs cooler and overclocks like a champ
1) Definitely no. I am getting about the same performance as a decently overclocked 8800GTS 512mb.Quote:
Originally Posted by omega1alpha

Putting a VF900 on my 4850, after the stock cooler was idling at 72-74C and loading at 82C, the card now idles at 35-40C depends on fan settings and loads at 50-55C.
If you don't have another cooler to put on it, at least think about replacing the stock thermal paste. A S1 would also be a nice replacement.
Yes it is, but I don't think it will be easy to find those drivers. BTW, it's not the ATI drivers that are restricting CF on an NVIDIA chipset, it's a chipset drivers related limitation AFAIK.Quote:

Crysis is about 5 fps slower with 4850 and Crossfire is slower than with 1 card
All other games (Devil MAy Cry 4, COD4, Mass Effect, etc) seem about the same or a few extra frames going either way.
3dmark06 I'm getting around 14K on single 4850 and about 17.5K on crossfire
GTS card is getting over 15K at stock and 16.2K overclocked to 800/2000/1100
I had poor Overclocking on these 4850 cards. One hit 700/1100 with some instability and the other won't overclock a lick. I'm sure it's because of the poor cooling and low fan speeds at the moment. Overall, I wouldn't recommend this for crossfire on the P35 chipset. A single card 4850 might be slightly faster and/or on par with a GTS G92, but the GTS might be cheaper and it will smoke the 4850 with a decent overclock. I don't like the current overclock on these 4850s with current cooling. That's just my humble opinion. Others might do better with a different mainboard. Good luck guys.

The P5K DLX pcie runs at 16x/4x I think, therefore xfire would be very poor as you have stated. Not all P35 mobos do though.Quote:

That's just my opinion and I hope others have better luck. I know that most reviews have been positive, so I'm not sure what's going on with my rig. My X64 Vista is fully updated and my rig was rock solid with my G92 GTS. Also, I used driver cleaner before I installed the 4850s. I would recommend that you guys make sure that you purchase from vendors that have a flexible return policy. I'm not happy with the heat generated by these things and the drivers seem unstable in my rig.
Good luck to others who venture down the 4850 path.....
Your being much too hasty mate.Quote:

I'm sure you are right, but my biggest concern with these cards is the heat. I'm telling you these things run hot as hell. The crossfire performance is horrible on my mainboard, so these cards aren't for me. I'm sure others might be happy, but keep an eye on the gpu temps. I'm not knocking the product, but just sharing some honest thoughts.Quote:

I ebayed my 9800GTX for $275, right before the price drop, and i picked up 2 4850's for $300, i think i got a good deal for $25 bucks more.
Heh. That was an awesome move on your part :up:Quote:

Anyway, just take off your second 4850 (the one in the 4x slot) and you'll see that a single 4850 beats your "old" G92 GTS.
And don't worry about the temps, these new GPUs are ready for that (8800GTs used to do 105º with the old cooler). The lockups aren't temperature-related, that's for sure.
Really? It's prolly only temporary tough, and prices will go back up :stick:Quote:

A part of me was hoping the crossfire performance would awe me to death and that I might sell my GTS and keep the 4850s. 4850s no go for me. GTX 260 stepup here I come....Quote:
