Hi, what memory is faster?

Kingston 4GB DDR3 1333 (PC3 10600) KVR1333D3N9/4G
Timing 9-9-9-24-33
CAS Latency 9

or

G.SKILL Value 4GB DDR3 1600 (PC3 12800) F3-1600C11S-4GNT
Timing 11-11-11-28
CAS Latency 11

Here's a very brief explanation of how timings and frequency work, so you have the info to figure it out for yourself.

The "1333" is the speed in MHz...otherwise known as cycles per second. so it takes 1/1333rd of a second to complete one cycle.

The timings (9-9-9-24) tell you how many cycles it takes to complete each kind of operation.

So to find the "Theoretical" speed of the memory would be 1/(speed in Mhz) multiplied by (CAS Latency timing)...lower is faster. (Again that's a theoretical max limit, some applications respond better to higher frequencies, some to tighter timings).

Thanks a lot for your answers. So if both have the same frequencies but different timings,we opt for the lesser one, correct?

G.SKILL Ripjaws V Series 16GB (2 x 8GB) DDR4 3200 (PC4 25600) F4-3200C14D-16GVK
Timing 14-14-14-34
CAS Latency 14

and

G.SKILL Ripjaws V Series 16GB (2 x 8GB) DDR4 3200 (PC4 25600) F4-3200C16D-16GVK
Timing 16-16-16-36
CAS Latency 16
