Im planning to buy one but i can't choose
Corsair Vengeance Pro (PC3 19200), Kingston HyperX Best/Savage(PC3 12800), or the AMD R9 performance/gaming series (PC3 19200)
First time that im building a pc

Ttake this into consideration: bandwidth, latency, benchmarks.

Bandwidth = the 19200 / 8 = 2400 Mhz. So you can achieve theoretical maximum bandwidth of 2400 MBytes with this Corsair or the AMD R9.
The other factor is CAS latency. Look at the advertisement, the number is usually written right behind the bandwidth.

It is really hard to make a judgement between bandwidth vs latency. Both seem to cancel each other out, and it also depends on your application workload alot. If you simply use alot of ram and you use an application which uses huge amounts of data right in cpu, then a higher bandwidth might be better. However, if you have a gpu and a game which caches lots of data in gpu, then latency might be more worth looking at. That is how i think about it at least.

For your decision, it is really hard to evaluate. I recently went for 19200 stick with CL 10.

Also check for benchmarks (very important!!!)

In general, DDR 3 1600-1866mhz is the sweet spot for gaming, you gain almost nothing appreciable by moving up the chain. DDR 3 2400mhz will show its performance in other types of applications...ie video encoding.

If you're getting the DDR 3 2400mhz at an excellent price point, go for it.

thanks men, i already got it, corsair vengeance pro 1866

 


Bwah? How on earth did you arrive at any of that? Your post is pure nonsense

Higher bandwidth + good memory controller > tight primary latencies
