ATI 38**s will be really cheap says Inquirer.

but how will the the 3870 compare to 8800GT?

Dunno, majority seems to think 10-20% slower.

If that's the case, the ~$50 difference would still lead me towards a GT.
 
Damn. 3850 looks like it could be a great deal, if it comes out at that price I might regret getting an 8600GT.
 
THE MARKETEERS OF GRAPHZILLA just got another reason to call Daamit "an unholy alliance". We managed to find out the number of transistors that create chip known under RV670 codename, and the number is quite interesting one.

According to estimates, ATI's R600 chip featured between 700 and 720 million trannies, manufactured in 80nm process over at TSMC. RV670 is just a vastly improved R600 chip, with more precise units, integrated Xilleon decoder, complete UVD video-decoding engine, and comes without a 1024-bit internal, 512-bit external memory controller.

The RV670 has 666 million transistors, manufactured on a 55nm process, once again at TSMC. This only goes to show just how transistor-intensive the 1024-bit RingBus controller was.


666 the Number of the Beast.

When we talk about dies, R600 was around 420mm2 in size, whilethe RV670 is somewhere in the 180mm2 range. This is a massive difference, and proof of what more optimal design and manufacturing process achieved

While Nvidia placed more transistors in its G92 chip (putting the video engine in), ATI was able to cut down the number of transistors by a nice figure. Combine this with 80nm vs. 55nm process, and you can imagine just how much more ATI can lower the prices and offer greater value for the Yuletide shopping frenzy

The number of the beast is HD3800

I think this depends a great deal on whether the price remains close to $300. It is my understanding from earlier posts made around the time of the 8800GT launch that the original target price of the 8800GT/512MB card was supposed to be closer to $200. At that price point, the 3850 is no longer quite the bargain.

I really think we have to wait and see if/when the prices come back down on the 8800GT, after the initial early adoption rush is over. This, in conjunction with how ATI's product launch will further affect pricing, will ultimately determine which board will be the better buy.
 
I'm really wondering why ATI isn't using much higher clockspeeds for the HD 3870. 825MHz or 775MHz, whichever it ends up being, seems a pretty small increase considering a move from 80nm to 55nm. I would think that RV670 should be capable of 900MHz-1GHz on the core considering the chip is less than half as large as R600 and should be much cooler.

With the final clockspeed being only around 800MHz~, I'm hoping RV670 will be a very good overclocker.
 
What is the direct competitor for the 3850? The 8800gt? How fast is it supposed to be?
Faster then the x1950xtx?

never mind ........8800gt Thanks

Yes I know that but look at the prices in the REAL WORLD. Does it look like it's coming down anytime soon? Prices have gone up since the launch.

Probably a little shy of 8800gts 320meg version.

Agreed, but this is not surprising to me. The demand was insane. Capitalism at it's finest. We are still over a week away from ATI's official launch anyway, so I'm willing to wait it out before declaring a winner.
