DDR3L 4gb VS DDR3 8gb

celliott5 · Feb 1, 2015

So I have two computers I am looking at and I am trying to do some research of my own but I would like more opinions.

The first two laptops are the main ones I'm looking at the last one is a higher price and I dunno if I would like to spend that much.

I also found that the Asus in the second link has "shared graphics memory"

What is the difference in shared graphics memory and an integrated graphics card. And which one would be better ?

Out of the listed laptops which one would be my best option ??

The main purpose of this laptop would be school and daily tasks. Nothing big.

Thanks for all of your help guys

The 'L' in DDR3L means low-power. It uses a lower voltage RAM, that can help with power consumption, albeit not a huge amount.

Shared graphics memory means that the video is integrated into the CPU and thus requires your system RAM to be shared with your graphics subsystem.

Essentially, it is meaning the same thing.

Only dedicated graphics has its own independent RAM, referred to as GDDR.

I wouldn't recommend RAM below 8GB today, especially if your system is running integrated graphics (sharing system RAM).

As far as those laptops go, the Asus has a larger screen and a better CPU with an inherently better integrated GPU than the first Lenovo (i5-4202y vs i5-4210u) and the third Lenovo has the same i5-4210u.

I would recommend the two latter of the three.

From Wikipedia-
"Integrated graphics solutions, shared graphics solutions, or integrated graphics processors (IGP) utilize a portion of a computer's system RAM rather than dedicated graphics memory. IGPs can be integrated onto the motherboard as part of the chipset, or within the same die as CPU (like AMD APU or Intel HD Graphics)."

The laptops with the SSD will perform faster, quieter, and give better battery life. Screen size is simply personal preference. While I subscribe to the "more ram is better" crowd, if the use is simple tasks and school work, 4 gigs will work.

All three laptops uses DDR3L RAM so there is no difference except for the amount of RAM. DDR3L RAM uses 1.35v as opposed to 1.5v that DDR3 RAM uses which means lower power consumption. All those laptop have integrated graphic cores (iGPU); the Intel HD 4400; which means the graphics core is inside the CPU itself and has no RAM of it's own. Integrated graphics uses system which means the 4GB or 8GB of RAM is being used by both the iGPU and Windows will be sharing the RAM. You cannot upgrade the RAM in any of the laptops. The RAM is soldered into the motherboards so you are stuck with however much they come with.

A SSD will allow the laptop to be more responsive because data can be read from / written to the SSD much faster compared to a hard drive. This means the laptop can boot up faster and programs will load faster. How powerful a laptop is depends on the CPU itself though.
