From an ad: "DDR3 components are twice as fast as today's highest speed DDR2 memory products."

Is this true? I remember reviews comparing the two and finding small improvements, but as DDR2 development is dead DDR3 may have moved ahead since then.

Or is it just hype? 3 is twice as much as 2?

Standard base clock it's really double, but this won't translate in double performance.
Others components will be struggling the performance, so it doesn't matter if u get faster, and faster, and faster memories. The gains are marginal for basic computing.

(If u going to use DDR3 1066 vs DDR3 1600 in a Llano plataform, u will truly have gains in the IGP though)

the ram itself is double the speed, however ram speed is rarely the limiting factor in normal workloads, therefor you get the double speed but only small improvements in benchmarks
