for the pure gamer at heart, the 4870 seems to be a steal.

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 could
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.

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).

The real key is what all the prices on these cards are when Nehalem is released.

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.

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 opinion

I wonder where they tested these cards? My 4850 runs between 52C idle and usually never above 65C while under load. I just use ASUS SmartDoctor which allows you to control the fan speed. Before using smartdoctor the fan speed never changed and it did run at 80C under load.

WTF is going on with those locked minimum clock speeds? I'm already pissed off by HD 3870 running at 300/1126 in XP, what a waste of power! Why don't they offer the possibility to manually (in control panel) underclock the card all the way down to 150-200/300-400 MHz is beyond me.

This is because just like underclocking a CPU there is a minimum frequency and a minimum voltage that is needed. Also these are gaming class GPUs aimed at raw power(= more power use + heat)and not really to be energy efficient. Although energy efficiency (usually goes hand in hand with heat output) counts to a certain extent when OCing and higher clock speeds these negatives of lower energy efficiency can be overcome through better HSFs/smaller manufacturing process etc.

Yes, the idle clocks aren't going nearly low enough with the current BIOSs. I've actually seen a BIOS floating around that had the right idle clocks (160/500MHz I think). Hopefully this will be corrected soon.

On a separate note, what's up with RV770 and UE3? I hadn't realized until now that the GeForce cards really pull ahead in those tests. With any other engine it wouldn't be that big a deal, but UE3 is kind of important.

Re 4850/4870 temps at idle and load - FAN SPEED WORKAROUND!

Check This Out!
http://www.techpowerup.com/64398/ATI_Radeon_HD_4850_Fan_Speed_Workaround_Posted.html

AND this!

This was the first info I found re temp/fan controls.

Seems you can dial in a lower temperature by changing the stock fan speed. And you can tweak your preferred noise level. Interesting read. I expect driver updates, as do others. I copied this info, cos I get a feeling it's going to be del'd. (?) Personally, I have not done this, cos I don't have a card :) to do it on! :) But it's a HOT item.
