DDR3 VS DDR3L VS DDR4

Buy new memory, it is recommended that we consider all the parameters, not necessarily the higher the specification parameters that means better performance.

1.

DDR3 VS DDR3L:

DDR3L RAM, which is the same pin as the DDR3 RAM, DDR3L is compatible with DDR3 RAM-enabled CPUs and motherboards, the only difference between the two is that DDR3L RAM can operate at 1.5V and 1.35V while DDR3 RAM remains at 1.5 V.

But in the Haswell platform is not fully compatible with Intel Haswell processor, in order to better Reduce power consumption, which supports only DDR3L memory type, and can not be compatible with DDR3.

(Considering about the cost,compatibility and the breadth of the application,all of our RAM is DDR3L till now and in the near future,any unknown wether change to DDR4 till now.pls keep focusing on us. )

2.

DDR3L VS DDR4:

 

(a)DDR4 RAM looks faster but much expensive than DDR3L.higher transmission rate means that there is more bandwidth, so that more data can be transmitted at one time.

Another memory performance parameter is the memory frequency, which is mainly used to identify the RAM data read and write speed, expressed in MHz (MHz) memory frequency is the number of cycles per second memory can be executed.

Finally, in the discussion of RAM performance must also consider the memory access time required for the delay of CAS Latency.Even if your memory has a very fast clock speed, high latency will also affect RAM performance.

If we compare the four types of pirate ship memory, it is clear that higher clock speeds and higher LC rates of DDR4 memory are not always better performance.

Name Type Clock Speed Delay Result
Corsair Pirate Ship Avenger PRO DDR3L 1600MHz CL9 9 / 1600MHz = 0.0056
Corsair Pirate Ship Avenger LPX DDR4L 2400MHz CL14 14 / 2400MHz = 0.0058
Corsair Pirate Ship Ruler Platinum DDR3 2400MHz CL11 11 / 2400MHz = 0.0045
Corsair Pirate Ship Ruler Platinum DDR4 3200MHz CL16 16 / 3200MHz = 0.0050

 

(b)DDR4 RAM is more expensive.

when DDR4 release first the price is quite high, till now the cost of DDR4 RAM is still high. From the table on the pirate ship memory comparison, DDR4 compared to DDR3 is not necessarily the best price.

 

(c)DDR3L and DDR4 how to choose it?

In fact, the choice of DDR3 or DDR4 memory mainly depends on the other hardware you are currently using, using DDR3L will have better compatibility and performance balance.many computer in the market now do not support DDR4,because DDR4 is not compatible with DDR3’s memory interface,while most computer motherboard design competitive DDR3,On the other hand,the price of DDR3L is more competitive and more tractable than DDR4.

 

Buy new memory,we should consider all the parameters, not necessarily the higher the specification parameters that means better performance.
