Hey, that's cool.
A bottleneck might not be gotten rid of in such a linear manner. It's almost like having 1GB of memory versus 512MB.
So many people were clamoring that 1GB was a waste for a HD 4870 compared to 512MB, but I gladly paid extra for 1GB with my 4870.
When I got an X1900XTX on the day it was released, I thought for a long time that it had more than enough memory bandwidth at 1550MHz GDDR3. Overclocking the memory by 100MHz hardly yielded any results at all. However, when an X1950XTX was released with 2000MHz GDDR4 memory (that was proven to have "equal" latencies), it proved the world wrong to the point where people were willing to pay an extra $100 just for 450MHz faster memory alone.
Perhaps the only high-end card that ever had "more than enough" bandwidth was a HD2900XT.
The bottom line here is that as we move forward, we appreciate boosts and increases in technical specifications. A 5870 sported a 100% increase in core specifications but only a 23% increase in memory bandwidth over a 4890. I am one-sided in clamoring for more bandwidth, not just for argument/debate's sake....
I' don't say you're wrong, I just partially dissagree with your stance
Memory bandwith is very important, however a smart and efficient design is much more important in my opinion and this is exactly what ati was aiming for. They tried to increase the calculation productivity while still staying in a certain size, energy consumption and cost frame.
I do believe all the woes with the 5870 are mainly driver/software related. Why else would a pair of HD5770s which theoretically provide the same computational power constantly outperform the single 5870? They do use the same architecture and offer similar bandwith (2x76Gb/s), don't they?
Edit:
I based my asumptions on the Guru3d tests found http://www.guru3d.com/article/radeon-hd-5770-review-test/16 . The 5770 pair's advantage varies, sometimes going up to 25%, but on average they are about 7% faster. When you consider that we don't get a perfect 100% scaling in crossfire, this is indeed a noticable difference isn't it?
