Without the proper architecture to support it DDR4 RAM is useless and just PR hype from Crucial.
Sometime late Friday a promo landing page appeared on Crucial’s website announcing that the beginning of the DDR4 era would be before us in less than two months time.
DDR4, the successor to the stalwart DDR3 protocol that was first introduced in 2007, promises to use 20 percent less power (1.2 V vs. 1.5 V) while delivering twice the speed and more memory density on boards. While DDR3’s clock frequency theoretically maxes out at 2400MHz (with the majority of DDR3 RAM in mainstream computers clocked around 1066MHz), DDR4’s clock speeds begin at 2133MHz and will likely have a ceiling just north of 3200MHz. DDR4 will support a transfer rate of 2133–4266 million transfers per second, compared to DDR3’s 800 to 2133.
The problem is until 2014 DDR4 will be a stick without a slot. The first chip to support this new memory platform will be Intel’s Haswell-E, which is expected to be released sometime in mid-to-late 2014. AMD doesn’t yet have a platform that is known to support DDR4, which means it will continue to use DDR3 until at least late 2014 or early 2015.
With a platform that supports DDR4 at least six-to-nine months away, there really isn’t a reason to get excited it yet. In all likelihood, Crucial wanted to get marketing materials up and something shipped to channel before its quarter or year ends in order to satisfy the brass of parent company Micron and its investors. After all Micron has its next quarterly report on December 19, and it’s a winning bet that news of being one of the first out on the market with DDR4 RAM will get prominent play.
