Performance difference between DDR and DDR2?

[Mithan]

Questions:

1. Is there a real performance difference between DDR1 and DDR2? I have yet to see any comparable reviews between the two.

2. Will DDR2 motherboards use DDR1 memory? (at lower speed of course)

Thanks.

For background, my issue is this:
I have a AMD 64 3400 with Socket 754 and 2 x 512 megs of ram but I want to upgrade it it by sticking in 2 x 1024 Megs now, then next year upgrade to an X2 based CPU and just carry the 2 gigs over, thus saving me memory and giving me the 2 gig benefit now.

However, the new M2 cpu's/motherboards coming out in Q2 of 2006, murks up my plans, because it supports DDR2, so you can see the reason for my line of questioning above.

1. No.
2. DDR2 is DDR2 only. DDR1 is DDR1 only. Some motherboards have both.

DDR2 is the future...... but its still in its.... tinkering stage?

so don't bother buying unless you must ...for some unknown reason...

some unknown reason being that you have a P4? hmmm. anyway, ddr2 memory will be a lot different when m2 comes out. at least that is what amd is hoping. they expect it to have similar latency to ddr now, with ddr2 speeds. therefore, even if you could use ddr2 in your mobo now, it wouldnt be a good idea because ddr2 now sucks compared to how it will be in 6 months.

Early 2006 AMD moves to the 333 DDR2 integrated memory controller. If you look at the latencies and prices of DDR2 they are now dropping close to DDR1 territory and AMD will jump in right when DDR2 has matured to a latency point that makes sense for them.

Not to mention availability and lower prices due to the natural maturation process and crossover of facilities that are making DDR1 to DDR2.
