The
Inquirer has a comparison of DDR2 and DDR3. As you can see from their
benchmark, DDR3 won over DDR2 between 3% and 19% in the results, more so in the
bandwidth tests - somewhat expected, as after the first word, the rest of the
words in the burst ticks at twice the rate, and shortest burst rate is now 8
transfers, compared to 4 in DDR2. This brings out the DDR3 bandwidth benefit
further. It looks like the DDR3 is beginning to mature - this is still not such
a bad latency, after all, and the results do benefit from it. Now, if just the
price improves downward, as fast as the latency does.
