ATI Removes NDA on Performance Previews for 4850 (#'s Inside)

Nice card for $200, but unless the 4870 is significantly better, I'm once again disappointed with ATI's lack of a high end card. I absolutely do not accept x2/crossfire as a high end alternative due to microstutter, so I guess I'll be looking at nvidia's gt200 55nm refresh... oh well.

One thing you forgot to mention, as stated in the review (!!!)...:

"Under load the HD 4850 gets quite hot, but not too hot. Actually I prefer this over a card with a noisy fan."

pwnd? grow up :rolleyes:

there has to be compromise between fan noise and heat and 95.5 degrees sure as hell isnt it.
 
Personally, I could give a crap about how hot anything gets. So long as it is within engineered tolerances, I'm fine.

Heat is an enemy. but it is only the enemy if it stops your box from working as it should. Never understood why peeps spend hundreds to go from 60c to 40c with no increase in o/c from the 60c mark.
Ok, so you can keep your system for 10 years, whereas mine will die in 6... pfft.

The 4870x2 GPU's are designed not to be crossfired through the bridge chip.
So the microstuttering issues should be greatly reduced (hopefully eliminated)

Wow, the bold really made me a believer!:rolleyes:

Just like they said the 2900 was a GTX killer?

When I see a qualty review that agrees with that, then I'll believe it. Until then I'll assume the 4870x2 will be plauged with the same microstuttering that the rest of them are.
 
Watching whines and whimpers from NV fanboys trying to justify the 280/260 pricetags is lollerific.
I never understood fanboys having any allegiance to any hardware company, all hardware companies are doing in the end is charging you for hardware and getting free marketing from your fanboyism. Essentially fanboys are paying companies to market their products for them. :rolleyes:

I will buy whichever product delivers the best value, it is almost impossible that to deny that ATI has taken that crown this time.

Then wait until the reviews come out. It's a completely new tech. Why the same old assumptions?
 
The past week, I've heard more about this "microstutter" then I ever have before.. ever. Someone care to explain what exactly it is? And can you actually notice it? From the time I've played with two 8800Ultras, I've never noticed it - nor have I ever read reviews mentioning it.

It only occurs in games that don't scale well with SLI or CrossFire. So it's fairly limited to multi GPU setups, however, it can also occur when there is not enough RAM.

Video of (Micro)Stuttering with RAM: http://www.corsair.com/cinema/movie.aspx?id=507445

The stuttering in that video is more noticeable then the stuttering from multi GPU setups, but this is to give you an idea. Hope this helps!:)

Its what Nvidia fans say to discredit ATIs approach of going multi core ;)
 
I will say that Nvidia fanboys are ten times more vocal.

Just call an AMD card acceptable, no matter the criteria, and they pounce.

It's like a wild eyed zealot foaming mad, I tell ya.

Microstutter is a special-limited-edition-once-in-a-lifetime accessory that you will get if you buy two or more HD 4850s together You will find it in the box together with the Crossfire bridge and the DVI-HDMI adaptor. If you don't want it, you need to pay an extra $250 but you will then get just one card instead :p

It is actually just an excuse to justify the $250 price difference between GTX280 and 2x HD4850s. If you have a 790FX mobo, you can have 3x HD4850s for the price of the GTX280.

that video is such bullshit, it's ridiculous

i've played through the entire game on 2gb and it was perfectly smooth.

Just added the Techreport tests. They seem to run 4xAA and 16xAF in every test so if you're looking for those numbers at 1680x1050, 1920 x 1200, and 2560 x 1600 against all the Nvidia cards, look there:

Heh, they really loved the 4850, since it actually beat the GTX 260 in Assassin's Creed and GRID in this preview. Real-world gameplay sessions too.

Just makes the wait for [H]'s review much worse.

Corsair.com bud, what did you expect?
I also think it's complete bullshit but check the source, what else can you expect...
 
I can't wait for [H]'s review. And if the card is too hot, I'll put an aftermarket cooler on it. Would have done it anyhow. Single slot coolers simply don't cut it.
 
Well good news I guess is that the 3800 and 4800s share the same slot so coolers that worked on the 3800 (cept the full-cover ones for RAM i think) will work on the 4800's.

Can you think of any other games that stress a gpu besides Crysis at a decent resolution?
Click to expand...

No but it is not the be all and end all of benchmarks. Just because the card may perform poorly at Crysis or some other game does not mean it will suck at all others. Not all future games will run off the Crysis engine. You can't take home much from the PCPer preview because they test two games. The reviews that test 7 or 8 games, I would say that the 4850 beats the 9800GTX in the majority of benchmarks.
 
What about people who don't even play Crysis?
I couldn't care less how many frames ANY card gets in that game.
 
I wish [H] would hurry the balls up ><

I'm eager for them to trash all the other reviews then have to deal with the hoards of kids running rampant calling [H] sellouts to nVidia.

:rolleyes:
 
seems thats only thing that nvidia fanboy can do now ignore other reviews and leave in his little world :)
 
Yep added theirs

Also, I want [H] to take their time with their reviews, no need to rush it. If they went to the Monday event, they probably only had a day to play with the cards
 
wow they really did fix AA. sweet. the 4850 is owning the 9800 GTX, thats sweet took. it will be down to $150 in no time plus we get dx 10.1.
 
This card only seems weak in 3D Mark Vantage and Crysis, not the end of the world. :) This might make more sense for me as having a P35 motherbaord I can eventually use CF.
 
Just spoke with some AMD reps, and it seems like the 4850s are going to be released tomorrow. Some are already being sold on Newegg, as well. :)

Will post reviews, benches, and frames soon. :)
 
I have been back and forth on cancelling my order to wait for a 9800GTX when the price drops, but this card is beating the 9800GTX in just about every category. They say its compared to a 8800xxx, but in reality it beats them too.
 
Don't forget (like someone else said) it only uses a single 6-pin while the 9800GTX uses, what, two 6's? Less power, less heat.
:)

They'll have dual-slot 4850's, no doubt, but I bet you won't find the dual-slot necessary.
 
Enjoy the fun fellas... last post for 6 months... off to Iraq :( I'll be looking at the refreshes :)
 
Keep your head down, toddw. (Though, damn, we've got enough warring factions going on right here...)
 
SLI has micro-stutter too - just a point. I have run both types of setups and its not like SLI is a magic bullet.
 
One thing to consider, my 8800GT overclocks 20% whereas the 4850 gets less than 10% so overall the 8800GT is quicker.
Its easy to get a 20% overclock on the GT with a 1.1V Bios mod, some can achieve it anyway :)

I'm waiting for the 4870x2 results!
