The Radeon HD 4850 was extremely quiet at idle, but its big brother can’t boast quite the same performance – despite the change to a dual-slot fan, the Radeon HD 4870 tends to be a little less quiet at idle according to the sound-level meter, even if the difference is relatively slight in practice. At 1045 rpm – only 12% of its maximum rotation speed – its fan can still be considered quiet.
Under load, the trend was reversed. While the HD 4870 is clearly not as quiet as the Radeon HD 3870, it’s still tolerable overall (the fan ramps up to 1600 rpm), and a lot quieter than the very noisy GeForce GTX 260.

finally ATI is getting some loveReply
I have the 4950 and it is great
nice review..I wonder why the 4850 can not render race driver : GRIDReply
for the pure gamer at heart, the 4870 seems to be a steal.Reply
however, what are the possibilities for a CUDA like processing environment or handling Physics engines? I think AMD has done a great job making a pure video card, but I believe the future will be with unified technologies of having the GPU assist in other tasks as well.

Would REALLY help alot if there were charts with these new cards and some of the last gen (what's in the desktop charts now) that way I couldReply
see how much I could gain by upgrading. Maybe thats an update to the desktop charts that just hasnt been dont yet? Seems like it would have already been.
Under load, the heat sink did its job and the temperature didn’t rise all that much – at least not as much as the little Radeon HD 4850.Reply
The 4850 went up 6* and the 4870 went up 10*... I think the 4870 went up more, but you (Tom's) said it went up less.
LOL you don't even have your drivers working properly if a 3870 and 3870x2 are matching each other in performance. Crossfire on the card isn't even working properly, check any bench of a 3870x2 vs 3870 in Call of Duty 4 (ATI preferred drivers).Reply
The real key is what all the prices on these cards are when Nehalem is released.Reply
LOTS of enthusiasts are planning a Nehalem build toward the end of the year. I image they will be getting 4850/4870s or GTX260/GTX280s. All depending on where the prices are I imagine.

I agree about the charts. I don't consider buying a 4870 vs an older card like an x1950, but it sure would be nice to see how much it has improved over time.
Thank you ATI. Though I won't be buying your card cause I just bought an 8800 GT maybe this will force nVidia to drop there prices and give me a cheap step up :D.Reply
I loved ati since the rage era, im so glad they are back in the game again, i might even consider trading in my 9800gtx sli for a 4850 crossfire down the line, maybe when i setup to ddr3. But for now best bang for the buck cards are the 9800gtx and the 4850 in my opinionReply
