The 4850 doesn’t consume a lot more power than the HD 3870. Will it be as acoustically discreet?

Radeon HD 4850

Excellent news: At idle, the Radeon HD 4850 proved to be the quietest card we tested – it was all but inaudible despite a fan rotation speed of 1490 rpm, thanks to the fan’s size (that rotation speed is only 27% of the maximum speed).

Unfortunately, the same wasn’t true under load, where the noise levels of the HD 3870 are now only a fond memory. The fan ramps up to 3400 rpm, and while not unbearable, it’s definitely audible and a little annoying – subjectively speaking, a little more so than the 9800 GTX +. Admittedly, the single-slot design, with all that that implies (less heat-dissipation area, a thinner fan and the necessity of re-routing the hot air back into the case) is clearly a disadvantage the 4850 has to deal with.

Wow $200 in Best Buy for a HD 4850,
$450 in Best Buy for a GTX 260.
And the 4850 is pretty close to the 280.

Ouu the 4870 is going to give Nvidia a run for there money
for the first time in a while.

Good stuff now we just need some 4870 benchies!

Oced Asus and 4850 instead of 4870 + too many games based on engines favoring nVidia...

P.S. +1000 -> 2222

Florian you put a 1920×1077 image on the Crysis page! :lol:

For Mass Effect the Engine limits the Maximum framerate to 62FPS. You can change this in the BIOENGINE.INI file (in the Documents\BioWare\Mass Effect\Config\ folder on Vista) by changing the value:

MaxSmoothedFrameRate=62 in the Engine.GameEngine section

I can't believe it took nVidia coming out with a new card again to have tom's make a review finally of the 4850.

"it was unavailable due to the sloppy handling of this launch"
Seriously? AMD can't control if their retail partners screwed the pooch on the release date, because they were so anxious to get people this great product. They made sure the product was readily available well before the launch date.

They should be praised for not having a paper launch, not told that it was a sloppy launch, very poor form saying that.

Hell i went to best buy and bought 2 4850's on sunday, when the cards weren't even supposed to be available yet, the guy told me "they have been in stock for over a month in the back, they aren't supposed to be available yet but i can get two for you." Were the AMD police supposed to come and smack best buy on it's hand and keep me from giving them profits?

Sorry if i'm ranting, just put the blame where it belongs.

No offense, Fedy Abi-Chahla and Florian Charpentier, and thanks for the hard work, but I think the article should be revised a bit. First off, this should be a review of graphics cards.. not a burned out overclocked Asus motherboard. If you attribute your 4850 test crashing due to your motherboard.. why throw in results of 0 across the board for the 4850? You just corrupted your data and made the final fps averages meaningless, which is the thing people were generally interested in. Secondly, why in the world are you including tests that don't fit the definition of "playable" on any card in your test lineup (Crysis 2560x1600). It just throws off averages, as people aren't going to run this game at 7fps! If there's no card in the lineup that gets close to 30fps in a certain test, just move on! Save it for the quad crossfire or triple sli tests or something. You're giving high weights to resolutions that only a fraction of a percentage point of dedicated gamers can utilize (and those wouldn't bother with a single GPU). Lastly, please get those annoying gigantonormous screenies out of the review. It makes the review look like it was done by kindergarteners.

I didn't finish reading the whole article yet but was the driver hotfix and the current 8.6 driver applied to the 4850?? It improved performance and stability greatly as i saw, it make the actual clock speed the card is set it run nicely and gives it great overhead to overclock through the CCC

Who wants the Radeon 4800 full revew? (including the 4870, that do better than the GTX 280 in some games!)

http://www.hardware.fr/articles/72 [...] -4850.html

In french, but the graphs talk by themselves. Ho, and if you want a short translation = impressive and incredibly more efficient than Nvidia (if you compare the size of the GPU, yes it's A LOT more efficient)

These reviews are getting better! Although I have seen many benchmarks and tests of the 4850 before this, I still love seeing how the 48x0 line is doing against the green machine! Anandtech.com has a kill 4870 review!

The downside is the 4850 GPU temp! Makes me rethink about buying one...

Great read, I've read up on the 4870 on Anandtech as well and it's pretty much the same deal with completely dominating the new Nvidia cards. Performing like a GTX 280 at $100 cheaper. I love the amount of games benchmarked results can vary so much from game to game especially with CF and SLI. Good read!

This is quite the turnaround for ATI and we haven't even seen R700 yet. Good times!

I'm still waiting to see how the 4870X2 scales in crosfire before I make any decisions. My 8800 GT SLI setup is still beating out the GTX280 and scales better than CrossFire currently. Hopefully by the time the 4870X2 comes out ATI will have fixed the drivers and scaled the crossifre better for more games. What we all know is that obviously the 4870x2 will outperform the GTX280, we must then wait and see if Nvidia goes 260X2 or 280X2 to stay on top of the graphics King of the Hill game.

The next couple of months are going to be interesting.

extremetech.com has numbers up for the 4870.

Absolutely BIAS REVIEW!

The review uses OLD DRIVERS for the ATI cards & gets worse from there.

The drivers used for Nvidia's cards> ForceWare 177.34 beta. Release Date: June 15, 2008
The drivers used for HD4850> Catalyst 8.22 Release Date: July 17, 2006!!!

Oh I see. Because the motherboard can't run GRID, the 4850 gets a score of zero in graphics tests. That makes perfect sense. After all, anyone using this GPU MUST have the same mobo.

HardwareCanucks has a detailed 4870 review also.

mikeinbc > How can you believe that a 2 year-old driver can support a new generation GPU? The 8.22 beta driver was simply the only driver available that supported the 4850 at the time of review. It is more something like a Catalyst 8.7 beta.

Malovane > Unfortunately we needed to review Crysis in 25*16 in order to be able to calculate the average framerates of each board with each resolution, including the 25*16 that is playable on most games. And to show that no board can currently run Crysis in 25*16.

"If you attribute your 4850 test crashing due to your motherboard.. why throw in results of 0 across the board for the 4850?" > No, I attribute the crashing to the Asus Radeon 4850 TOP that we reviewed.

By the way, as I explained again in the review, I didn't include the 0 score of the 4850 with GRID in the sum-up benchmarks.
