say.. anyone knows what's the difference between DDR2 and DDR3
RAM? as in how much better the performance would be for about 4GB
of it?
Can't really compare because they require a different
connection. Laptops use DDR2 now, if I'm not wrong. PCs use
DDR3.
Performance wise, DDR2 is pretty much 3x slower than DDR3. By
speed I don't mean the 'size' it comes in (ex 512mb, 1gb, 2gb) but
the read, write and response speeds.
But if you're looking to upgrade, there are grades like
DDR2-400, DDR2-533, DDR2-667, DDR2-800, DDR2-1066. 1066 being
fastest.
DDR3-800, DDR3-1066, DDR3-1333, DDR3-1600 for the DDR3
series.
Wiki should have the speeds iirc.
