Anandtech Review

At the risk of having my comment unread on the actual review, I just wanted to congratulate Anand and Derek on an extremely well put together review! While I'm not a hardware or software engineer and can only pretend I know all of what you're explaining in the article, what I was able to gather gave some great insights into both the RV770 and GTX200 architectures.

Now, if AMD/ATI can just introduce a 4870X2 at or under the $500 price point, things could get extremely interesting.

Haven't they been talking $449,-??

I don't see how the X2 can cost less than 2x cards unless they cut something *ahem GDDR4*

It's GDDR3 or GDDR5. 4 is a generation that doesn't count... just like DirectX... and Winamp

Why is that? The HD3870 used GDDR4.

While ATI has used GDDR4, the marginal speed increase over high-clocking binned GDDR3 is offset by the higher latencies. GDDR4 usually clocks in the 1000-1200 MHz range on reference designs... That is not uncommon for high-clocked GDDR3, which still retains better latencies (albeit at higher power consumption).

GDDR5 is in effect almost QDDR (900 MHz GDDR5 = 3600 MHz GDDR3 effective speed) while providing a nice reduction in power requirements. Case in point:

HD 3870 @ 1125 MHz GDDR4 = 72 GB/s
HD 4850 @ 1000 MHz GDDR3 = 64 GB/s
HD 4870 @ 900 MHz GDDR5 = 115 GB/s

actually, qdr would be 900mhz=1800mhz, as DDR is doubled already
