Double data rate type three SDRAM (DDR3 SDRAM) is a type of synchronous dynamic random-access memory (SDRAM) with a high bandwidth ("double data rate") interface, and has been in use since 2007. It is the higher-speed successor to DDR and DDR2 and predecessor to DDR4 synchronous dynamic random-access memory (SDRAM) chips. DDR3 SDRAM is neither forward nor backward compatible with any earlier type of random-access memory (RAM) because of different signaling voltages, timings, and other factors.
DDR3 is a DRAM interface specification. The actual DRAM arrays that store the data are similar to earlier types, with similar performance.
The primary benefit of DDR3 SDRAM over its immediate predecessor, DDR2 SDRAM, is its ability to transfer data at twice the rate (eight times the speed of its internal memory arrays), enabling higher bandwidth or peak data rates. With two transfers per cycle of a quadrupled clock signal, a 64-bit wide DDR3 module may achieve a transfer rate of up to 64 times the memory clock speed megahertz (MHz) in megabytes per second (MB/s). With data being transferred 64 bits at a time per memory module, DDR3 SDRAM gives a transfer rate of (memory clock rate) × 4 (for bus clock multiplier) × 2 (for data rate) × 64 (number of bits transferred) / 8 (number of bits/byte). Thus with a memory clock frequency of 100 MHz, DDR3 SDRAM gives a maximum transfer rate of 6400 MB/s.
DDR4 is a pretty hot discussion topic right now, and we became curious... can you expect to see a tangible performance benefit from running DDR4 compared to DDR3, keeping all other variables as close to the same as possible?

Wondering what's new with DDR4? Linus tells you all that you need to know about 4th generation DDR memory and we do some performance numbers comparing DDR4 to the old spec DDR3 using gaming, synthetic, and real-world application benchmarks.

It started on a Labor Day
A chance for us to get away
Everyone in the house
And year by year things moved around
But everybody still got down in the house
And seldom do we have a plan
But everybody lends a hand
Everyone in the house
Making sure we have our fun
While gettin' done what must be done in the house
Pardon me, did you say something?
What are you looking at?
Tell me, what's your problem?
Are you counting heads?
Are you counting things?
What are you looking for?
Listen there's no problem
'Cause we got them, we already got them
We got family values

Politics and money scams
Endless verbal traffic jams
Keep it out of the house
'Cause you'll get what you give to me
A little r-e-s-p-e-c-t in the house
'Cause you know some of us have been around
And some of us still get around
But we all in the house
So don't get on our evil side
'Cause we like it rough and we're nationwide
Pardon me, did you say something?
We're all entitled to have our own opinion
And you're standing there like you smelled something
But you're entitled to even bad opinions";Many of our generation glamorize

We gonna have a good time everybody
Because the family is all in the house!
