Yes, yes its much better. Games very rarely use more than 512mb graphics memory. Thats right, 2gb cards are a total gimmick.
DDR2 is slower than DDR3 due to their difference in bandwidth. DDR3 has a higher bandwidth hence can transfer data at higher speeds than DDR2.
It is not very noticeable if you upgrade your memory on your computer.
DDR3 uses lower voltage
The difference between the memory of the DDR2 RAM and the DDR3 RAM are the capacity that they can hold the DDR3 RAM is more powerful than the DDR2 RAM.
DDR3 runs at higher clocks and lower voltages due to a more complex 90nm manufacturing process than DDR2 Ram. So therefore, DDR3's main difference in comparison to DDR2 is better power usage and higher clock speeds.
DDR2 RAM is SDRAM. It provides double the bandwidth of DDR RAM, but at a higher latency. DDR3 is much better than DDR2 performance-wise, and it uses less voltage.
It depends what you configure them to be on the Dell website. I5 is better than I3, DDR3 ram is better than DDR2, SSD HD's are better than disk drives etc.
DDR3 memory provides a reduction in power consumption of 30% compared to DDR2_SDRAMmodules due to DDR3's 1.5 V supply voltage, compared to DDR2's 1.8 V or DDR's 2.5 V.
Unfortunately, no. DDR RAM will not work in a DDR2 motherboard, and DDR2 RAM will not work on a DDR3 motherboard. There are a few motherboards that have slots for both DDR and DDR2, so it is conceivable that there could be motherboards with slots for both DDR2 and DDR3.
Here's what I found out for you. The DDR3 has 240 pins just like the DDR2, however, they will not be compatible, you will not be able to put a DDR3 into a DDR2 slot. The knotch on the stick of RAM is in a different location so it will not fit. So a new motherboard made for DDR3 will have to be used. They are currently out on the MAC Lite computers but not sure if Microsoft has any on the market yet. The DDR3 will use 1.5V, which is lower than the DDR2 1.8V.
No, DDR2 is quite slower than DDR3. DDR4 was released very recently. DDR4 is currently the fasted SDRAM available.
ddr3 can achive much higher clock rates than ddr2. the highest possible clock speed of ddr2 is 1333MHz while there are already 1800MHz ddr3 sticks being produced. also ddr3 can support twice as much capacity per stick than ddr2. Answer DDR3 in several significant ways: * Higher bandwidth due to increased clock rate * Reduced power consumption due to 90mm fabrication technology * Pre-fetch buffer is doubled to 8 bits to further increase performance
