[Newegg] 3870x2 w/ GDDR4 spotted.

I don't know how big a news this is considering the 4850 and 4870 are coming out @ the end of the month. Still thought it to be news-worthy tho.

They should've done that from the start, or atleast offered both flavors (GDDR3 and GDDR4).

Agreed. It was the 3870X2 after all and not 3850X2, lol.

There was supposed to be a GDDR4 model soon after the initial launch of the 3870x2. Better late than never eh?

Yup, I actually might have purchased the 3870X2 GDDR4 instead of the 9800GX2 if it had been available when it came out.

Nice find! Interesting cooler on that thing. Three DVI and even an HDMI is a nice upgrade from the reference card. Anyone have an idea how this compares to it's older GDDR3 cousin?

The memory clock speeds the GDDR4 version runs (2250mhz) it would have a memory bandwidth of 144 GB/sec (using GPUReview). The stock GDDR3 version only runs at 1800mhz for the memory clocks which gives it a bandwidth of 115.2 GB/sec.

Slightly Old News for Me

Im Still Trying to Figure Which would get better performance. They Tell me its only good for Benching and not so much gaming.

Btw That Cooler is Fugly and Will Dump tons of Hot air inside the Case

I agree with the cooler on this card. If we're talking about a 6600GT, I don't think it's a big deal whether or not GPU heat is exhausted from the case but this thing is a different beast. The reference cooler with a subtle nudge from RivaTuner's fan control is still the best for these cards.

If that extra memory bandwidth doesn't really do a lot for real-world gaming then could it be as simple as the memory is being bottle-necked by the GPUs themselves? Perhaps the bridge device that links the cores? I wonder what would happen if you upped the core a little...
