Intel don't seem to be hanging around - a leaked roadmap of the processors puts the recently released Haswell processors being "refreshed" half way through 2014.
It won't be long after the refresh that the 14nm Broadwell chips are planned for release, which will of course need a new, dedicated socket...
There seems to have been a leaked roadmap from a Chinese website called VR-Zone, which shows some interesting details about future Haswell-E and Broadwell CPU platforms.
We know that the Ivy Bridge-E CPUs will release in Q3 this year, and will be compatible with the LGA 2011 socket. Even before that release we're hearing information about the Haswell-E CPU's, with an estimated release date of Q3/Q4 2014.
Currently, not much is known about the X99 CPUs, but we can be sure that they will support SATA Express. Also, the X99 Haswell-E CPUs will probably be backwards compatible with the LGA 2011 socket, as well as be compatible with the LGA 2011-3 socket. This new X99 platform is also probably going to be the first set of CPUs to bring DDR4 support to the market.
There are a few possiblities:
1. Intel makes LGA 2011-3 motherboards with DDR4 support; Haswell-E is backwards compatible with LGA 2011, but LGA 2011 won't support DDR4.
2. Haswell-E WON'T be backwards compatible with LGA 2011, but will support DDR4.
3. Haswell-E won't be backwards compatible with LGA 2011 or support DDR4 - this is the worst case scenario, and probably won't happen, but we can't say for sure.
What are your thoughts on the timing of the releases, is Intel rushing the entire process? How much longer can we keep shrinking CPU's? Tell us below!
