I haven't heard of them discontinuing the GDDR 3 version.
It's not so much that there was news that they discontinued it, just that I don't think there was ever any hard evidence that it would be done beyond engineering samples (I could be wrong).
|The 4850 board features 512 MB of GDDR3 memory and is expected to be available in volume at launch.
AMD will follow up in July and launch the Radeon 4870 512 MB GDDR5 and the 4870 X2 1024 MB GDDR5 (R700)
The 4870 includes 512MB GDDR5 memory and surpasses upcoming Nvidia cards in terms of bandwidth. However, if any ATI partner wants to build a 1024 MB GDDR5 board, ATI will not say no, we were told.
It doesn't mention a GDDR3 HD4870 at all, and I'm sure that if AMD was going to launch one alongside the GDDR3 HD4850 they would want to be talking about it. I haven't personally read any article about the launches that mentioned a version of the 4870 with GDDR3, and I don't think one was ever planned. If AMD was going to release a GDDR3 model, why wouldn't info have leaked yet? So far the only card that any significant details have been revealed about is the 4850 w/GDDR3, not even with GDDR5. The lack of info on GDDR5-based cards I think lends credibility to the rumor that the 4870 is being delayed so that it will launch with GDDR5. If they're going to delay it, there's no point in also releasing a GDDR3 version.
Of course, I could be wrong, and the lack of 4870 info is just a coincidence
