16GB 1333(CAS latency 9) vs 1600(CAS latency 10)?

I'm upgrading ram on my laptop pretty soon. Searched many threads about 1333 vs 1600 and almost make no difference plus the price is similar. Since I'm paying same price, should I get 1333 with 9 CAS or 1600 with 10 CAS)? The 1333 is 9-9-9-27 and 1600 with 10-10-10-27

 

Buy 1600 of course.

I am well known in this and you should know that CL9 1333 and CL10 1600 means totally the same CL measured in milliseconds. BUT the difference in speed still stays 1600 is 30% faster than 1333.

To sum it up. You WILL see a difference between those 2 RAM. But all that tests and benchmark do not show you smth which only your eyes will notice. The system will become much more snappier and smoother.
Trust me. Only if you try faster RAM you can say smth about it. Everyone who bought it understood that it is indeed better.

Absolute BS. The only places where the differences are tangible are in synthetic benchmarks and when playing games on an integrated GPU.

 

I wish I could use a dislike button now. Whatever! I am not going to change your atrophied point of view.

@Infinite24 You can see there 2 links. 1 of which shows changed mind of a guy who I argued with a lot of time about the same question. And he saw a difference in jumping from 1600 to 1866.

Anyway, it is nobrainer if the price is almost similar. But I will always buy 1600 RAM. 1866 is too expensive for now I would say.

 

Have to agree with James D,

especially if the system in question is a newer IB platform.

Don't even need to use it with an igpu, the 'snap' the O/S has with the 1600MHz RAM is noticeable.

 

Actually I have to agree with James D. I was a skeptic at first but, my W110er has unlocked RAM multipliers so I bumped up my 1600mhz CL11 Samsung sticks to 2133mhz CL12. The difference in the UI experience is very subtle, inconsistent and definitely requires an SSD to really become noticeable. To highlight, alt-tabbing is slightly faster, opening small documents is snappier especially if you do several at once and navigation with loads of tabs seems slightly less laggy. Where talking a difference in half a second maybe. I also tried 1866mhz with CL10 and the snappiness wasn't all that different to 1600mhz which leads me to believe Ivy bridge favors high bandwidth vs latency.
The Primary advantage to getting high mhz RAM is a much smoother IGP experience, the HD4000 doesn't get much better FPS wise but the microstutter almost disappears with higher memory BW, AMD's A10-5800K and A8-5600K 'Trinity' APUs reviewed - The Tech Report - Page 1
Definitely get the high mhz RAM if its not that much more expensive (say $10 difference), though to be honest, you'd notice more of a jump from 1600mhz-2133mhz, you probably can't discern 1333mhz vs 1600mhz. My personal order of preference is capacity>speed>latency.

 

In other words, you actually are agreeing with me.

OP, by all means buy the 1600 if it's the same price as the 1333. However, do not go in expecting some sort of game changing difference in performance because you won't see it.

 

I have to agree here, i didn't notice any important difference between my Sandy Bridge desktop with SSD and RAM running at 1333MHz and my M6700 also with a SSD and 1600MHz CL10 RAM. Maybe the difference between 2133MHz RAM and 1333MHz RAM can be felt more, but for the one the OP asked about, i have yet to feel any difference.

 

Same here, didn't notice any difference between 1333mhz and 1600mhz, but that was on a slower Llano notebook. Probably more of a placebo effect thing, imo.

 

Partly, there is definitely a noticeable difference, it would be wrong to suggest its only visible in synthetics but again its very personal, some people like me are very twitchy with my UI so the improvement was immediately noticeable.
I will blind test 1333mhz vs 1600mhz with my gf and report back, In truth I've only noticed the difference in going from 1600mhz and 1866mhz to 2133mhz, it would remove bias by having different machines/operator placebo etc.
For the sake of price, I completely agree with you.

 

you'd see a noticeable difference on memory intensive tasks like virtual machine performance or renderings, gaming as well.

I'd get the faster ram if it's the same price otherwise I'd look into an ssd first before buying faster ram

Yeah, SSD first, then faster RAM. Anyways, i haven't loaded anything really memory intensive on my M6700 yet so i can't comment in those, but for MS Office and Internet, i didn't notice anything. I will soon start running CFD on my M6700 though and i'll keep an eye out to see if i notice anything feeling faster.

I remember G series owners talking about an improvement in minimum framerate in gaming (a few fps, nothing staggering) even with dGPUs with faster RAM installed in their laptops. Given that depending on the laptop, a few fps can make or break a fluid experience, it might be worth it for that alone. I'd still go for a SSD first, it is what will give the most "snap" to your computer. As an example, with a SATA 6Gbps SSD, the MS office splash screens for word and Excel barely show. I can't read the whole text on the splash screen before it loads, i also have no idea what the animation looks like in it's entirety.
