4850x2 ?
- Thread starter etherone
- Start date
lmao, wtf?
So what would be the point of a HD 4850 X2 with only 512 MB of VRAM per GPU?
Do you think it would be much better than GX2? I don't. Not at all.
Doesn't the 4850 crossfire beat the GX2 in most situations? I'm sure there are some that the GX2 wins (thanks to the problems with crossfire and SLI scaling), but I thought the 4850 crossfire was better than the GX2 under most circumstances. I can't remember though, been a while since I've read the reviews.
However, I'm starting to think ATI have dropped the 4850x2. It was supposed to come out early september, we're now approaching mid october and haven't heard anything (that "leaked" performance graph was actually an older graph).

512 MB of framebuffer in a multi-GPU set-up isn't enough in my opinion. Why would one spend 300+ dollars on a HD 4850 X2, anyway? It makes no sense. You may as well get a GX2 for 250.
I just read some of the benchmarks of Crossfire Hd 4850s vs GX2...they are neck and neck.

A 4850X2 is better for many reasons.
-Of course the 4850X2 will be a 1GB per GPU card. The 4850's are using 1GB of VRAM now, why would the more expensive part use less memory (per GPU)?
-A 4850X2 would benefit from the driver optimizations ATI has done for the 4870X2. Nvidia haven't done the same level of optimization for SLI, since their high-end videocards do not depend on SLI scaling, and not causing problems. For Nvidia, SLI is just a gimmick, while Crossfire is an important part of ATI's high-end videocard strategy. If anything, too good SLI support for the GX2 would hurt Nvidia's sales of GTX260/280 cards..
-It wouldn't suffer from micro-stutters either, like the GX2 does. This means better scaling and better performance in most popular games (except Crysis). The GTX280 and GX2 are also neck to neck but it isn't about the raw framerate, it's about having a consistent framerate with no stutters.

ha ha ha ha.
Its like saying 1gb 2900xt would bet a 512mb 4850 because the 2900xt has 512 bus compared to a 4850 with a 256 bus.

weird. i'd rather get a 4870x2 and will at any rate
1. Manufacturers always add more mem to everything. Look at the 8500 1GB or was it 2GB
2. You're a bit oblivious to how Crossfire does not scale well in just as many situations as SLI
3. See above.
I'm well aware that Crossfire doesn't scale well in all games. I started a thread about the poor Crossfire scaling in less popular games at Rage3D and was torn to pieces for it 
But in general, in the most popular games, Crossfire helps where as SLI is terrible most of the time.

List 5 games were the 4850 doesn't scale that good. And crysis and crysis warhead do not count.

ATI is probably waiting for nVidia to make it's next move (rumored to be later this month) before they release the 4850 X2. I guess they don't want to cannibalize their 4870 X2 just yet.
aaawww, well i was hoping it would be sooner rather then later, that way prices have time to drop ^^. Seeing as the 4870x2 is in the $450-550 range $450 Being a GREAT SALE i would hope 4850x2 to be in the 400$ range, and with prices dropping and maybe a sale a 300--350$ 4850 is probabley more then i will need for a WHILE (1680x1050res gaming)

That's not what the reviews are saying. Show me where a 4870 1gb beats a 4850 crossfire setup.
4850s in crossfire are silly fast. The 512mb vram will only hold you back if textures are cranked on Crysis and that don't count lol. Everything else in every other game can be maxed including AA. I want to see some 4850 1gb in crossfire benchmarks.

I'd agree with You if it's GX2 vs GTX 280 (hell even GTX 260), but in this case of 4850x2, even with [H]'s method of real gameplay, not average FPS, 4850 in crossfire setup wins the GOLD award.
Have You read this ?

GTX 280.
- Less heat.
- Less power consumption.
- Newer tech.
- Can be acquired for almost the same price (if you play your cards right).
- Less driver issues.
- No microstuttering issues.

what are some of you guys on about? according to ATI slides the 4850x2 will be 1gb per gpu for 2gb total.

I don't agree with it. I'm not a sheep that listens to everything [H] says. I think multi-GPU set-ups need more than 512 Mb of RAM per GPU to be effective. That's from my experience.
I don't buy the Crossfire > SLI thing...because you read nothing but complaints about Crossfire on various forums, incl. [H]. And i've had SLI...it's okay...but once you start overflowing your 512 MB framebuffer limit with high textures, AA, etc....games start to suffer over a period of hours.
Last I checked the 4850X2 was going to be 2GB of GDDR3, 1GB for each GPU.
Considering 1GB 4850's are ~$180 AR (cheapest I could find), this card would need to be priced at about $350 to be competitive. I don't think there's any way they could keep the 4870 1GB's at ~$300 like they are now. Prices would probably have to drop so that 48701GB's are <$270 and 4870 512MB are <$225 for the whole series to follow a decent price/performance curve.If that's the case...i'm all for it. As long is the price is decent.

every slide from a few weeks ago said it was a 2gb card and the price would be $399. that price doesnt sound all that great now that 4850 has went down so much in price. price will probably be lowered in a week or two after it comes out once the early adopters overpay.If that's the case...i'm all for it. As long is the price is decent.

I guess I'm a sheep.
I agree that with current level of 4850 512 MB performance, it'll need more than 512 MB per GPU.
Personally, I'd stay away from anything other than one-GPU one-card solution, but I don't mind recommending at least 4850 in CF based on [H] review.

You know... Because tech engineering never advances. Because when you go from 70 fps to 141 fps... something's wrong.

Right, if I use Dual-GPU card, then I'm two sheeps.

Which games does the 4850 in crossfire not scale well. And if you say crysis or warhead, you sir are a HW.

Just one fine example :
http://www.xbitlabs.com/articles/video/display/sapphire-radeon-hd4850-cf_10.html#sect1
Unless You call that 25 fps vs 26 fps is scaling well
I don't play Crysis, infact, the newest tittles i played is Mass Effect, that's why I said "personally", do You not get the meaning of the word "personally"?
Well, I don't need You to attack my personal opinion and calling Me HW and no need for Us to continue to hijacking this thread, thank You.

This is a very nice post. I like it, It's just missing an inkiling of proof or linkage to back it up....
1)Proof? Anywhere that the GPU still exists on AMD's road map? and that if it exists it will be using 1GB memory? Just a small reminder that 1GB 48XX parts have only shown up in the wild just recently. And if AMD release a 300$ 4850X2 they rape their own 1GB 4870 parts at the same price point.
2)SLI has been around longer than Crossfire, since it was nvidia's intiative.Crossfire played catch up for the past GEN and has now become a viable solution with the 48XX line.
Also, Nvidia DO NOT TAKE IT AS A GIMICK, do you know why? Because their chipset business is currently based around it. If you notice SLI configurations can only be had on Nvidia Chipset Powered Mobos, and even now that SLI will be available on some X58 mobos they will have to be certified by Nvidia or Drivers won't support them. Does that seem like monkey business to you?
3)BEEP BEEP BEEP, Crossfire also suffers from microstutter on some games, ask anyone who's played COD4 on a crossfire rig. Crossfire has only come into it's own with the 48XX series and even then it doesn't scale at all on some of the biggest titles that need more horsepower.

I did not call you a helmet wearer. I said if you would have listed crysis or warhead for the 4850 cf not scaling well, then you would be considered a helmet wearer. Also that is the worst review I ever saw. They showed the 4870 beating it in most games when that just isn't the case. It looked like they crossfired the 4850 on a sli board lol. Don't trust one review because some sites tend to be bias like inq (hates nvidia) and xbit from what it looks like. I am sorry but something was wrong on their setup when they reviewed it. They had Cod4 not scaling at all when everyone knows that is one of the games the the 4850 cf scales great at. Here is an apples to oranges.
Cod4 2560x1600
http://enthusiast.hardocp.com/article.html?art=MTU1OCw5LCxoZW50aHVzaWFzdA==
goes from 37 (lower settings) to 58 (highest settings)
http://www.xbitlabs.com/articles/video/display/sapphire-radeon-hd4850-cf_5.html#sect1
didn't even test the 4850 by itself, and they had only 33 fps on crossfire.
How is it that [H]ards single card performs on the same pace as xbits crossfire setup. I am not trying to call you out, but I just feel that you were misinformed by a bad source.
What's funny with that X-bit review... HD 4850 Crossfire doesn't scale in COD4, but absolutely smokes COJ.
"The Radeon HD 4850 CrossFire subsystem wins in every tested mode. It is over 50% faster than the GeForce GTX 280 but its bottom speed is no higher than 20fps. It means the game may be jerky and sluggish in complex action-heavy scenes"
This is why I don't like HD 4850 with just 512 MB in Crossfire.

Well when and if it does come out I am willing to bet an arm,( maybe not a leg) that it will be 1Gb per GPU to total 2Gb, just like was done with the 4870x2, along with optimization I am pretty sure it'll be a pretty decent card to say the least, and (dare i say it ) better then the GTX 260 SLI.
If that turns out to be the case GREAT, it will be an awesome card for its price.
Also, 4 weeks after its release if its not at $300 that will be disappointing considering the cost of cross-firing 2 4850s, fine fine i understand the whole 1gb per gpu thing but still the 4870 x2 is at $550 max and its 4870 counter part is at $300 max. So even though it might be a bit suicidal for Ati, "4850x2 at $300 Please."
P.S. loved the sheep thing ^^

You can't compare on what to be obviously different setting and setup, and what was very obvious is the difference of Their AA and [H]'s AA. But COD 4 is not My point, basically I'm telling You about older games (such as WiC) that doesn't benefit from SLI or CF, even when They do, it's just not as well as in the newer tittles (and the one that likely being used by reviewers on Their sites). Unfortunately, I do a lot of My gaming with those older tittles, that's why I called it "personally".
You just missed My point, but thanks
